Telstra launches NEXT G network

Telstra has launched its new "NEXT G" 3G network with much fanfare today, promising real world speeds of between 550Kbit/s and 1.5Mbit/s to customers nationwide.

"No one else, here or abroad, has built and launched such a far-reaching, high speed, wireless broadband network in less than a year", said Telstra CEO Sol Trujillo. "It is a versatile, high capacity network with head room for higher speeds in the months and years ahead".

Like its competitor Vodafone, Telstra is using High Speed Downlink Packet Access (HSDPA), with theoretical maximum download speeds of 3.6Mbit/s. Telstra claims that in March next year it will be able to offer peak speeds of up to 14.4Mbit/s and in 2009 up to 40Mbit/s. But based on existing disparity between claimed and actual speeds for wireless networks, the real world performance for the end user is likely to be much lower. Telstra admitted that users will initially see speeds of between 550Kbit/s and 1.5Mbit/s.

The emphasis in Telstra's briefing today was on two things — coverage and content. In terms of coverage, Telstra says its network is larger than all the other 3G networks combined, and will reach up to 98% of the population.

In terms of content, Telstra touted all of the traditional mobile products — video calls, mobile TV and music downloads. These are already available from competitors, but Telstra will be hoping that the breadth of its content will be attractive to potential customers.

To use the service for broadband data access, Telstra is offering a "NEXT G turbo card". But pricing looks to be extremely expensive, with initial plans offering 1GB for a whopping $109.95/month.

But there was no mention of ADSL2+ or Fibre to the Node, which was the big news at a similar briefing 12 months ago. AFR claimed yesterday that Telstra will not roll out ADSL2+ until it can get a guarantee "that no competitors will be granted wholesale access to the service...except on what it considers to be commercial terms."

Vendor Market Share: Sony Ericsson the World's Fastest-Growing Mobile Vendor in Q3 2006

Summary

An all-time record 256 million mobile phones were shipped worldwide in Q3 2006, up 22% from a year earlier. Amid further signs that `Razr mania' has peaked, Motorola lost its crown as the world's fastest-growing top-six vendor for the first time since Q1 2005. High demand for the Walkman and CyberShot ranges helped Sony Ericsson to grow quickest, at 43% annually, compared with a slightly lower 39% from Motorola. Meanwhile, Nokia reached its highest mark for 3 years, registering 89 million units for a 35% share. Samsung gained sequentially one point of market share, due to healthy sales of its new Ultra Edition portfolio of slimphones. In contrast, despite the wildly popular Chocolate family, LG registered just 6% annual growth; its slowest rate since our records began. BenQ-Siemens continues its seemingly unstoppable slide toward market exit. Following 716 million units shipped in total globally during the first 9 months, Strategy Analytics maintains its forecast of 1.00 billion units / +22% YoY for the full-year 2006.

Analysis

Nokia surged to 35% global market share, its highest level since Q4 2003. Sales have been driven by soaring demand for entry-tier devices in emerging markets such as Africa. Nokia has, for yet another quarter, impressively continued to hold off ambitious competitors such as Motorola and Sony Ericsson. Following 242M shipments in the first 3 quarters of 2006, Nokia is well on its way to surpassing a record 340M units for the full-year.

Motorola grew shipments at a healthy 39% annual rate during Q3 2006, due in part to stronger sales across major developing markets such as India and China. However, there are emerging signs that `Razr mania' has peaked.
First, Motorola's total shipments were growing at a peak 2.6 times the worldwide industry average in Q3 2005 -- this ratio had slipped to just 1.0 times by Q3 2006. Second, Motorola (39%) has lost its crown to Sony Ericsson (43%) as the world's fastest-growing top-six vendor for the first time since Q1 2005 -- this is illustrated in Exhibit 3. Third, the competition is offering up many alternative choices for mid-range or high-end GSM consumers -- Samsung has an improved slimphone portfolio (e.g. Ultra Edition), while LG has the Chocolate family and Sony Ericsson offers the popular Walkman range. Finally, a recent survey by Strategy Analytics' Advanced Wireless Laboratory (AWL) service in Western Europe and North America found that some end-user segments may be tiring of ultra-slim designs and `just being thin' is no longer a strong selling point. Clearly, the ball is back in Motorola's court and the pressure is growing for it to replace the unique, blockbuster Razr model which has driven its stellar performance over the last 2 years.

Samsung registered a below-average 15% annual growth rate in Q3 2006. However, this was up markedly on the weak 8% rate of Q2 2006, due to surging demand for its range of Ultra Edition slimphones. Samsung sold globally 3 million handsets under the Ultra Edition sub-brand, representing almost 10% of total volumes during the quarter. The 12.9mm D600 slider proved by far the most popular model, accounting for roughly half of all Ultra Edition sales.
Sony Ericsson overtook Motorola as the world's fastest-growing (and most profitable) top-tier brand in Q3 2006.

High demand for the Walkman (5M units sold) and CyberShot (2M units sold) ranges helped Sony Ericsson to grow at 43% annually, compared with a slightly lower 39% from Motorola. Interestingly, Sony Ericsson is also the world's most profitable top-tier vendor -- at 15% operating margin, it now outstrips even Nokia (13%), Motorola (12%), Samsung (11%) and LG (4%). An increasingly confident Sony Ericsson is talking openly about moving eventually into the number three position currently held by Samsung. However, we think this goal is a bit of a stretch in the near-term, given the 55% gap in present volumes (20M vs. 31M).
LG increased volume by a below-average 6% rate year-over-year during Q3 2006. This was its slowest growth rate since our records began. Nonetheless, healthy global demand for its high-end Chocolate range helped operating margins return to a more respectable 4%, from a weak 0% during Q2 2006.

BenQ-Siemens shipped an estimated 6 million units globally during Q3 2006. Testing delays of new products in part held back total volumes. Despite an encouraging pipeline of improved models, such as the EF91, BenQ has opted to withdraw financial support and the outlook for the loss-making Siemens division appears bleak, although its recent major staff cutbacks should help to better balance the firm's supply with its potential demand.

Following 716 million units / +25% YoY in the first 9 months, Strategy Analytics maintains its forecast for 1.00 billion units / +22% YoY over the full-year 2006. None of the top OEMs reported noticeable inventory-build across key markets during the quarter.

Fashion and Style in the Mobile Handset Industry

In developed mobile markets, consumers are becoming more sophisticated in their selection of handset, and this is driving a market for stylish and fashionable mobile phones. In this research report, it shows that there will be sufficient consumer demand to support the sale of 23 million fashion handsets by 2010.

There was a time when companies such as Nike, New Balance and Reebok produced 'running shoes'. Now, these pieces of footwear sell in fashion boutiques, and vintage lines can trade for huge market premiums. The mobile phone is following a similar path, and fashion boutiques have become the point of sale for handsets from Siemens/ESCADA, Nokia/Versace, Vertu and the now defunct Xelibri. In addition, fashion designers such as Kimora Lee Simmons, Diane Von Furstenberg, Anna Sui and Vivienne Westwood have readily extended their design expertise onto handsets from Motorola and Samsung. Will we one day see mobile phones being sold in fashion boutiques? We are already there. In the space of 15 years, the mobile handset has moved from a niche telephony device, to become the most ubiquitous item of personal consumer electronics worldwide. This has made it an obvious tableau for the expression of an individual's fashion tastes and style.

The handset is a fully mobile device: it travels everywhere with its owner and is visible to others. To make a call it is placed to the side of the head. To compose a text, the device is held out in front. It is laid out on tables in office meeting rooms and school canteens, beside you in restaurants, and at the bar. The handset can act as an ideal canvas for an outward and visible statement of the owner's tastes and values.

Fashion is the ever-changing pattern of consumer tastes, driven by a wide range of random events. Events such as war, a shift in house prices, the introduction of a new technology, or the emergence of a new musical sound, can influence the consumer taste curve. In practice, fashion is something more specific. It is a set of seasonally driven colours, styles, and motifs that are combined and mixed in a huge variety of ways by a wide range of parties in order to appeal to targeted consumer demographics. This is not restricted to designers sending dresses down the catwalk, but also includes car manufacturers, furniture producers and mobile handset manufacturers, among many others.

A fashion handset is one where the consumer's purchase decision is based primarily on the aesthetics of the device. The aesthetics include both the styling of the device as well as any brand associated with it. Today, the primary conduit for fashion and style into the handset market are the handset vendors themselves. As a result of the increasingly commoditized conditions in the handset industry, the return on technology innovation is falling. In an age of standardised handset platforms, it is increasingly difficult for Tier One vendors to differentiate theirproducts from that of low-cost, Asian ODMs by simply adding enhanced technology features.

For the consumer faced with a range of seemingly identical devices from a technical perspective, fashion and styling allow a reasoned, value-driven consumption decisions to be made. The aesthetics of a device can generate an emotional response by consumers, to which they will ascribe a value and for which they will pay a premium.

The result is that fashion and styling are playing an increasingly important role in the profitability strategies of the handset manufacturers as they strive to distinguish their products in the market. This has been, and will continue to be, a key driver of fashion into the mobile handset market. The report examines the fashion and style strategies employed by the major handset vendors in the market today. These strategies fall into four groups, consisting of: the incorporation of fashion and styling elements across a handset portfolio; co-branding collaborations with fashion brands; formation of a sub-portfolio of handsets geared specifically at the fashion and style conscious market; and the establishment of independent, fashion focused handset subsidiaries. Nokia is the only vendor adopting all four strategies, while Sony Ericsson employs just one.

Four case studies are presented, analysing fashion and style ventures executed by handset vendors and mobile operators. These include Siemens' Xelibri, the Siemens ESCADA venture, Nokia's Vertu and the Vodafone range of Ferrari handsets. For each, we look at the rational behind the project, the benefits achieved by both the fashion and technology partners, and we provide a critique of these projects' successes and failings.

There are clear benefits for the mobile operators in distributing fashionable and branded handsets through their channel, including opportunities for customer retention, customer acquisition, ARPU growth, enhancement of brand values and subsidy removal. However, there are also a number of difficulties for operators in becoming involved with these devices, and much of these issues revolve around conflicts of brand.

It is the holy-grail for handset manufacturers to sell more than one handset to each mobile subscriber. A user might have a daytime handset for power use, and a sleek evening handset with fewer functions, but a more fashionable form factor. Vertu and Xelibri were more about creating fashionable and stylistic handsets, but multiple handset ownership was the side-effect in some cases. While the mainstream consumer market has not widely demonstrated a desire for multiple handsets, the report examines how fashion handsets will drive the market for secondary phones.

Fashion brands have entered into partnerships with Tier One vendors to produce co-branded fashion handsets, however, none have taken the next step: independently producing their own-designed phones, outside of an operator or vendor collaboration. We contend that the mobile phone market has matured to the extent where a portion of the market will derive 'utility' from the device's styling and branding. This is an audience to which fashion brands can deliver more value than the current handset vendor brands who are tied into their technology and engineering roots. The report outlines the type of fashion, brand and lifestyle companies for which there is a handset opportunity and discusses the factors which will incentivise these companies to enter the market, as well as the barriers which will restrict some of them.

The report presents two specific examples of how fashion and brand companies can leverage themselves within the handset market. We look at two companies, Diesel and Jaguar, providing a background of these companies and details of their brand position. We then present concept designs for handsets which these companies could launch and target at a fashion and brand conscious market. Created by design firm, Ocean Observations, these concept designs are based heavily around themes and idioms closely linked with the brand, and cover the design of both the external form factor and the graphical user interface. A discussion of how these example companies might go about retailing their fashion phones within the market place is also presented.

We believe that the global wrist watch market is an effective example of how the global handset industry could mature. An overview of the watch industry is presented, highlighting the fashion, style and brand components of this market and drawing parallels with the commoditizing handset industry. We believe that consumer behaviour in watch purchasing will be mirrored in handset purchasing when the mobile phone market has matured sufficiently. By mapping the consumer purchasing segmentation of the watch market onto a future, mature, handset market, we determine a measure of future demand for fashion handsets.

As the market matures and consumers' handset tastes become more sophisticated, demand for fashion phones will increase. We estimate that, by 2010, sufficient consumer demand will exist to support the sale of 23 million fashion and luxury fashion handsets. While this will account for just 2% of all handsets shipped worldwide, the sale of these phones will constitute 12% of handset retail revenue.

First 3G Fashion Phone for Nokia


Above from left : Nokia 7360, Nokia 7373 and Nokia 7390.

Europe : Building upon the success of last year's highly popular L'Amour Collection, Nokia has unveiled three new mobile phones to meet the growing demand by stylish consumers the world over. From the elegantly iconic Nokia 7390, Nokia's first 3G fashion phone, to the truly desirable Nokia 7373 and the timeless Nokia 7360, each model from the latest L'Amour Collection draws its design inspiration from tribal art and ethnic decoration. The result - a beautifully designed, intelligently considered and exceptionally crafted range of mobile phones, in a palate of colours and textures to meet every desire.

Finding inspiration in the faded luxury of grand architecture, the models from the L'Amour Collection will be appreciated as much for their exotic design as well as their impressive sophisticated set of features. Forms remain modern, round and pure. An earthy palate of colour and traditional materials, updates the bohemian feel of the earlier collection. Aspects of embroidery, 3D applique, ceramic tiling and other traditional decoration are refined and modernised through a new craftsmanship - resulting in beautifully embossed leather finishes and graphics which are sublime yet eclectic. Further unexpected combinations enhance the splendour of the L'Amour Collection, as does the mix of traditional handcrafts with cutting edge technology. The collection espouses a 'nouveau-ethnic' feel - the muted tonality and bleached colour reflecting fashion's new and sophisticated way of incorporating decoration.

Nokia 7390: Professional elegance with a modern edge

This sleek, elegant fold phone, consummately blends precision technology with groundbreaking design. As Nokia's first 3G fashion phone, the Nokia 7390 combines exquisite materials and design innovation within a fully featured phone. The 3 megapixel camera and WCDMA high-speed connectivity is subtly hidden within ceramic-inspired shell and leather panels. Ideal for a 24/7 lifestyle, the Nokia 7390 is available in two colours, a Bronze Black version provides a masculine feel, echoing cigar parlours and oak-panelled studies of a by-gone era. The Powder Pink model is a daring combination of ceramic white and powder pink, a colour palate currently found on fashion catwalks and furniture fairs.

The estimated retail price of the Nokia 7390 is expected to be approximately EUR 450, excluding taxes and subsidies.

Nokia 7373: Metropolitan style, fluid form

Ethnic patterns and a compact swivel design gives the Nokia 7373 its fresh look and perfect grip. Elaborate tribal markings provide a unique point for contemporary design interpretation, where form and decoration are married seamlessly together. This results in finely tooled surfaces, exquisite detail, embossed finishing and further decoration when the mobile phone is opened, proving that the Nokia 7373 is a veritable treasure chest of reference and culture.

The Nokia 7373 is available in Bronze black, Powder Pink and Black Chrome, with a wide array of complementary graphical themes. The estimated retail price of the Nokia 7373 is expected to be approximately EUR 350, excluding taxes and subsidies.

Nokia 7360: Subtly styled, elegantly compact

The Nokia 7360 is an elegant and compact mobile phone, subtly styled with accents inspired by metal, leather and transparent surfaces. The innovative use of materials gives this mobile phone its unique character, which evokes modern design classics. A tactile inlayed leather effect gently wraps around the phone, meeting smooth ceramic-inspired surfaces and glistening metallic details. The Nokia 7360 comes in two colour options. A chrome and black original that is strong, streamlined and reliable. The Powder Pink girlish, charming and undoubtedly the phone that Lewis Carroll's Alice would have used had she needed to make a call from Wonderland.

The estimated retail price of the Nokia 7360 is expected to be approximately EUR 200, excluding taxes and subsidies.

The renewed L'Amour Collection is a universal journey of romance, a fusion of technology with traditional craft and a union of ancient art with modern communication. Each model from the L'Amour Collection is expected to begin shipping this fall.

Fixed-Mobile Convergence – FMC

UMA-based dual-mode WiFi/cellular:
Positives:
· Is engineered from the ground up around "seamless" handover. This is both a positive and a negative.
· Phones and semiconductors becoming available
· Standardised & now adopted by 3GPP as GAN
· Reasonable range of infrastructure providers
· Relatively cheap to deploy at first
· Possible usage cases for MVNOs
· Good, cellular-grade security and authentication mechanisms. UMA may well be reincarnated as a security technology. Good way for operators to learn about FMC customer experience, marketing proposition, support etc.


Limitations:
· Limited and expensive range of handsets
· Not suitable for large enterprise
· Does not currently support 3G
· In practical deployment, requires operator-provided gateway
· Could be blocked by broadband operator in the network
· Potential for huge customer service & support costs
· Assumes that usage over WLAN should give the same "user experience" as over cellular - ie not intended for "bearer-aware" applicationsDoes not work well with multiple WLAN access points (no standards for connection management software)



IMS / VCC-based dual-mode Wi-Fi/cellular (VCC = voice call continuity):
Positives:
· Based around a clear vision of future IMS-based operator networks
· Significant levels of enthusiasm from major operators
· Exploits growing use of SIP in both handsets and networks
· Wide range of equipment vendors supplying pre-standard convergence solutions
· Some operators already skipping UMA and going straight to pre-IMS dual-mode
· May be flexible enough to allow handset applications to be "bearer aware" Will do "seamless" handover


Limitations:
· No "full IMS" handsets available yet; standardisation will take some time.
· VCC standards incomplete
· Not obvious how interoperability with enterprise IP-PBX systems will work. Mobile IP centrex is not the right answer here.
· May be dependent on uncertain timelines / success of IMS rollout
· Uncertain dependencies on in-home infrastructure (gateway, WLAN, PC etc)
· Hasn't yet got sufficient awareness to drive innovative 3rd-party developers etc. May suffer from UMA failure fallout



Non-IMS SIP-based dual-mode:
Positives:
· Less pre-occupation with "nice to have" seamless handover
· Puts the customer (or a "challenger" service provider) in control
· Takes advantage of the growing number of handsets with "naked SIP" functionality
· Can work in the enterprise with PBX-integrated mobility manager
· Should be suited for "least cost routing" applications
· Works OK in multi-access point environments Good solution for "challenger" operators like VoIP providers, ISPs, broadband firms, foreign mobile operators etc


Limitations:
· WiFi-enabled handsets still tend to be expensive, poor on battery life, limited in numbers & expensive
· Difficult to do low-latency handover
· Installation, configuration & support headaches for using 3rd-party software on phones
· Potential problems with user interface or application blocking on handsets which have been operator-customised or locked
· Requirement for solution provider to focus efforts on handset software development, integration, testing etc
· More difficult distribution / subsidy model for handsets Will work best in markets/segments with low operator involvement in handset supply


Cellular HomeZones (such as O2 Genion and Vodafone ZuHause):
Positives:
· Drives fixed-mobile substitution
· Possible to use dual numbers, fixed- and mobile
· Uses standard mobile numbers Homes still tend to want fixed connection for broadband, and maybe IPTV in future


Limitations:
· Works best in markets with low penetration of mobile outbound calls.
· Low cost" cell radius may be very wide, driving cannibalisation.
· Possible IPR issues
· May mean unacceptably high costs for inbound callers
· May need extra intelligence / infrastructure in the network Opportunity for bundling with "naked DSL" looks attractive if permitted


Cellular Picocells & Femtocells:
Positives:
· Picocells already proven to work in niche usage cases
· Need fewer picocells to cover an area than WLAN APs
· Adds network capacity in-building as well as just coverage
· Use normal cellphones rather than complex dual-mode ones
· Can be backhauled with a cheap IP/ADSL connections rather than a leased line
· Licensed spectrum so less risk of interference than using WiFi
· Proliferating number of picocell vendors, silicon suppliers, VARs / resellers and related switching / application providers
· Given a huge boost by recent Ofcom low-power spectrum auctions in the UK
· May well be driven by requirements for indoor use of HSDPA and UMTS Lots of interesting niche business cases


Limitations:

· Sub-$500 "Femtocells" for residential services still at prototype stage
· Possible complexities around spectrum management & RF planning if there are 1000's of picocells in a city
· Complexity dealing with IT / facilities management personnel on-site
· Security issues - is a picocell "genuine"?
· Enterprise PBX integration with cellular can be difficult at a practical level
· Some signs that operators will need to deploy overlay LANs
· May be problems with roaming agreements outside buildings
· May require end-user to manually re-select networks on handsets
· May be dependent on broadband provider
· Issues around gateway integration, support for residential customers on IT issues etc



Fixed + Mobile service bundling:
Positives:
· Much simpler than many FMC solutions
· Possible to gain good percentage of FMC financial benefits (customer lock-in, new services, family plans etc) with little technical investment
· Various enhancements like closed-user groups (call Family mobiles for free, etc) No need for expensive/complex dual-mode phones or on-handset custom software


Limitations:
· Only really suitable for hybrid fixed+mobile carriers, or MVNOs
· Doesn't improve indoor cellular coverage
· Limitations in future migration path (eg to IMS)
· May add complexity in sales / provisioning (eg transitioning multiple family members from existing services & numbers) Possibly difficult to tie-in prepay subscribers


VoIPo3G or VoIPoWiMAX:
Positives:
· Potential to replicate Skype or similar in the mobile domain
· Decouples access from service provider, improving competition & probably prices
· More spectrum becoming available
· Reduces need for WiFi in handsets
· Future coding schemes will improve radio resource efficiency above circuit-switched voice
· May be used initially as a "second line" eg VoIP for international calls
· Fits well with introduction of SIP-enabled handsets Likely to be embraced by operators in the long term (probably CDMA first with RevA/B)


Limitations:
· Data plans currently mitigate against use, especially when roaming
· Heavily dependent on cell capacity for guaranteed QoS
· Poor indoor coverage, esp for WiMAX >2.5GHz
· Few phone-type devices at present (only PDAs)
· At present, very inefficient way of using radio resource
· May be difficulties with handset integration (eg access to codecs, echo cancellation etc) Very early days in terms of devices, use experience, integration etc

W-CDMA - Terms

RB - Radio Bearer
The service provided by the Layer 2 for the transfer of user data between UE (User Equipment) and UTRAN (UMTS Terrestrial Radio Access Network). Also in page 28, 25.321: “Dynamic radio bearer control is performed by RRC, based on the traffic volume measurements reported by MAC.” Each User Entity may have several RBs. The maximum number of RBs for each User Entity supported at current release is:
1. Maximum=5: e.g. 1 signalling channel + 3 voice channels + 1 data channel;
2. Maximum=32: for all other configurations
RAB - Radio Access Bearer
Term used in UMTS to identify the service the AS (Access Stratum) provides to the NAS (Non Access Stratum) for transfer of user data between the UE (User Equipment) and the CN (Core Network).
CPCH - Common Packet Channel
This is a contention based
UMTS channel used for transmission of bursty data traffic. This channel only exists in FDD (Frequency Division Duplex) mode and only in the uplink direction. The common packet channel is shared by the UE (User Equipment) in a cell and therefore, it is a common resource. The CPCH employs fast power control.

TFI - Transport Format Indicator
The Transport Format Indicator indicates the local
UMTS air interface transport format to be used for the transmission time interval.

TFCI - Transport Format Combination Indicator
This is a representation of the current
TFC (Transport Format Combination) being used. The TFCI is transferred across the air interface and allows the receiving layers to identify the current valid Transport Format Combination and hence, how to decode, de-multiplex and deliver the received data on the appropriate Transport Channels.

TCTF - Target Channel Type Field
The
UMTS air interface uses the Target Channel Type Field to provide identification of the logical channel class on the FACH (Forward Access Channel) and RACH (Random Access Channel) transport channels. TCTF indicates if BCCH (Broadcast Control Channel), CCCH (Common Control Channel), CTCH (Common Traffic Channel), SHCCH (Shared Channel Control Channel) or dedicated logical channel information is being transported.

TB - Transport Block
In
UMTS a TB (Transport Block) is defined as the data accepted by the physical layer to be jointly encoded. The transmission block timing is then tied exactly to this Layer 1 frame timing, e.g. every transmission block is generated precisely every 10ms, or a multiple of 10ms. Also in page 23, 25.321:”The Transport Blocks, shall be transmitted in the order as delivered from RLC. When multiplexing of RLC PDUs from different logical channels is performed on MAC, the order of all Transport Blocks originating from the same logical channel shall be the same as the order of the sequence delivered from RLC. The order of the different logical channels in a TBS is set by the MAC protocol.”
TBS - Transport Block Set
The Transport Block is defined as a set of Transport Blocks, which are exchanged between MAC and L1 at the same time instance using the same transport channel. A high rate transport channel carries more information and therefore potentially carries more transport blocks. Also in page 23, 25.321:”In the uplink, all MAC PDUs delivered to the physical layer within one TTI are defined as TBS. It consists of one or several TBs, each containing one MAC PDU.”

Transport Block Size
The Transport Block Size is the defined number of bits in a Transport Block. The Transport Block Size is always fixed within a given Transport Block Set. That is all Transport Blocks within a Transport Block Set are equally sized.

Transport Block Set Size
The Transport Block Set Size is defined as the number of bits in a
Transport Block Set.

TTI - Transmission Time Interval
This is defined as the inter-arrival time of
TBS (Transport Block Set), and is equal to the periodicity at which a Transport Block Set is transferred by the physical layer on the radio interface. It is always a multiple of the minimum interleaving period (e.g. 10ms, the length of one RF (Radio Frame)). The MAC (Medium Access Control) delivers one Transport Block Set to the physical layer every TTI.

Transport Bearer:
Service provided by the transport layer and used by frame protocol for the delivery of FP PDU

Transport Format
Transport Format is defined as a combination of attributes which include: error protection, timing, interleaving, bit rate and mapping onto physical channels.

TFS - Transport Format Set
The Transport Format Set is the set of different Transport Formats associated to a Transport Channel.

TFCS - Transport Format Combination Set
The Transport Format Combination Set is defined as a set of Transport Format Combinations on a Coded Composite Transport Channel.

CCTrCH (Coded Composite Transport Channel)
A data stream resulting from encoding and multiplexing of one or several transport channels.

TFC - Transport Format Combination
The physical layer multiplexes one or several Transport Channels onto a Coded Composite Transport Channel (CCTrCH). These Transport Channels each have defined transport formats (maybe from a Transport Format Set) which are applicable. However, at a given point of time, not all combinations of transport channels and their associated formats are permitted, hence a subset is defined. The Transport Format Combination is one of the subset, which identifies the transport channels with their chosen format that will make up the Coded Composite Transport Channel.

CFN (Connection Frame Number)
CFN counter. CFN is the frame counter used for the L2/transport channel synchronisation between UE and UTRAN. A CFN value is associated to each TBS and it is passed together the MAC-L1 SAP. CFN provides a common frame reference (at L2) to be used e.g. for synchronised transport channel reconfiguration.
The duration of the CFN cycle is longer than the maximum allowed transport delay between MAC and L1 (in UTRAN side, between SRNC and Node B, because the L1 functions that handle the transport channel synchronisation are in the Node B). Range: from 1 to 255 frames. When used for PCH the range is 0 to 4095 frames.

W-CDMA - Radio Bear Realization

The UTRAN standard does not mandate how to realize radio bearers, i.e. what user plane protocol modes should be selected by RRC for a specific bearer service request. Below some typical realizations are outlined.
Conversational bearers may use PDCP if they originate from the Internet and have headers that should be compressed. For voice services originating from PSTN, PDCP is typically not used. The delay requirements are typically too stringent to allow for retransmission of erroneous data. Therefore unacknowledged RLC is used if segmentation of higher layer data units is required, and otherwise transparent RLC is used, which is the typical case for voice bearer services. The delay requirements typically require that the dedicated MAC mode is used. Streaming bearers with very stringent delay requirements may be realized in the same way as conversational bearers. However, for bearers with looser delay requirements, it is possible to use acknowledged RLC and common/shared MAC, which may yield higher capacity. PDCP usage is not affected by this.

Interactive and Background bearers typically originate from the Internet and hence PDCP is used. The delay requirements allow for acknowledged RLC and common/shared MAC. High priority Interactive bearers could use the dedicated MAC mode.
  • One Physical Control Channel and one or more physical data channels form a single Code Composite Transport Channel (CCTrCh). There can be more than one CCTrCh on a given connection but only one physical layer control channel is transmitted in such a case.
  • Frame Structure of Transport Channels: The UTRA channels use the 10ms radio frame structure. The longer period used in the system frame period. The System Frame Number (SFN) is a 12 –bit number used by several procedures that span more than a single frame. Physical layer procedures, such as the paging procedure or random access procedure, are examples of procedures that need a longer period than 10ms for correct definition.
  • Scrambling code: It is needed to separate terminals or base stations from each other. It would not matter if the actual spreading were done with identical code for several transmitters. The chip rate As the chip rate is already achieved in the spreading by the channelisation codes, the symbol rate is not affected by the scrambling.







SUPL (Secure user plane location)

A standards-based protocol that allows a mobile handset client to communicate with a location server over an IP connection, is a standard promoted by the OMA standards body and supported by location industry leaders. Openwave's SUPL support extends Openwave's established user plane expertise from CDMA and iDen into the GSM and WCDMA network areas.

SUPL is not another positioning procedure, but rather an alternative or complementary positioning architecture based on IP instead of SS7 signalling.

A positioning solution based on the user plane is less dependent on the core network and also reduces the load on the control plane.

In addition to much higher accuracy (positioning of within 5-10 meters), SUPL A-GPS offers the following benefits compared to stand alone GPS:

  • Faster time to first fix of GPS satellite
  • Better coverage
  • Longer battery life
  • Built into the device

Openwave Location Manager gathers a subscriber's location from available sources including cell-ID and Assisted-GPS (A-GPS) to securely deliver information to the requesting application. Providing accurate location information is key to the success and usability of location-intelligent services. A pioneer in SUPL solutions, Openwave deployed the first successful commercial user plane solutions at major wireless operators in several countries.

Openwave Location Manager provides several feature modules, including:

  • Content & Applications to enable its customers to offer state-of-the-art location services from a selection of applications
  • Access Management for application requests, subscriber privacy, and billing and operation systems integration
  • Positioning Management to obtain and/or calculate a subscriber's position using SS7 protocols, IP based technologies and/or handset location solutions
  • User Plane Management to support handset location technologies, including OMA SUPL specifications for A-GPS

Openwave's messaging, location, browsing and content services span all networks and devices. Today, Openwave software is used by more than 100 mobile operators, broadband providers and Mobile Virtual Network Operators (MVNOs) to enable access to data services for more than 500 million consumers around the world.

New Congestion Control System for 3G FOMA Network


From NTT DoCoMo's PR DoCoMo to Unveil New Eight FOMA "9 Series" Phones.


ASIA Japan : NTT DoCoMo said they would separately manage call and data packet transmission congestion over the 3G FOMA™ network to prevent voice traffic congestion control from affecting packet communication traffic and vice versa.

Currently, excessive congestion in either voice or data transmissions can force DoCoMo to limit network usage for both voice and data in order to prevent network breakdown.

One result of the move is the increased ability to successfully transmit text messages via i-mode mail, or to DoCoMo's i-mode™ Disaster Message Board service, even if voice traffic should rise sharply during a major disaster. The i-mode Disaster Message Board service, launched on January 17, 2004, enables i-mode subscribers to post text messages on a special i-mode site.
The new system will initially apply only to selected handsets — D902iS, F902iS, N902iS, P902iS, SH902iS, DOLCE SL, SH702iS, D702iF, N702iS, P702iD, and N902iX HIGH-SPEED.

A similar control system for the 2G mova™ network was implemented in April 2004.
