Rich Communication Suites - a Significant Convergence Initiative
It is almost easier to say what RCS is not than to say what it is: It commonly applications nor a set of services, but rather an enabling framework for services. Furthermore, although the RCS framework is managed rather like a standard, it is based on existing standards and specifications, for example, in the case of presence, it uses the framework of OMA Presence SIMPLE 1.1. RCS is closely bound up with the IMS architecture, which is sometimes offered our IMS, the RCS is intended to be a set of defined IMS-based services which mobile operators implement in a common way, thus making it easier for inter-operablity between them and between different vendor's technology components.

How to win the teltcom carrier's non-zero-sum game int his global economic crisis
Attracted by high ROI, several industries (e.g., Internet, Telecom, Cable/Satellite, and Media) are merging each other; therefore, not only traditional telecom carriers but also new comers (e.g., MSO and MVNO) are able to offer subscribers much abundant services in mobile-broadband markets. This trend obviously conducts tough marketcompetitions and reorganizes the telecom industrial chain. As a result, ‘How can be survived’ is a serious question for all telecom carriers, especially in the current global economic recession. According to analysis from the aspect of GAME theory, it is clear that this type of competition is a non-zerosum game due to uncertain number of players, services and subscribers. This article firstly analyzes the industrial trends and reviews literature resources, then proposes an approach, by which carriers can adopt corresponding strategies and tactics to deal with various market challenges. Finally, case studies are demonstrated as proof of concept.

How to realize software evolution of existing BOSS via ZTE SEEM
Due to long-term construction and accumulation for different purposes, telecom carriers normally have very complex IT environments, especially in BSS/OSS domains. Just like any other software projects, the telecom IT construction is a process always behind the market changes; therefore, ‘how to evolve or replace these legacy systems to support continuously changed market requests’ is a puzzle in telecom CIO/CTO’s mind. To answer this question, we need to know two methodologies (i.e., software maintenance, and software evolution). In this article, we would propose an approach, Software Evolution Enhanced Methodology (SEEM), which essentially is a methodology to evolve a legacy system with minimized pain and cost based on theory of software evolution. This methodology has been utilized in many previous projects successfully.

VDSL2--A Feasible Solution for "Last Mile"
ADSL plus is currently being deployed worldwide as the new mainstream broadband technology for residential and business customers. But at the same time, the industry is gearing up for the next step of the DSL evolution: VDSL . This second version of the very high-speed digital subscriber line (VDSL) standard from ITU-T promises to deliver 100Mbps symmetrical traffic on short copper loops.
The greater bandwidth of VDSL gives telecommunications operators the ability to offer advanced services such as multiple streams of interactive standard and high-definition TV over IP over the existing copper plant. TV services are fast becoming strategically important to telecommunication operators who are competing head-to-head with cable operators launching voice over IP (VoIP) and high-speed internet services.
ITU began drafting its VDSL standard (G.99 . ) in January 004. Consensus for the standard was reached at a meeting in Geneva in May 005. As with ADSL/ /plus, the underlying modulation in the VDSL standard is discrete multitone (DMT). VDSL is based on both the VDSL1-DMT and ADSL /ADSL plus recommendations. Therefore, it is spectrally compatible with existing services and enables multimode operability with ADSL/ /plus. VDSL extend the spectrum to 0MHz and can deliver 00Mbps symmetrical traffic on short copper loops at most.

Intelligent "None" Network Management, Brilliant OAM Helper10G EPON - Unleashing the Bandwidth Potential
The in-depth development of social informatization facilitated by the booming growth of data communications service enables Ethernet switch the key device in broadband network to get outstanding achievements in both quantity and quality. Currently, it is now trying to become more high-speed and intelligent. At the same time, due to the unceasing extension of broadband network, the complicated network environment makes network management even more difficult. Network manageability not only depends on network management solution, but also closely connects with the manageability of each basic network element. By improving the manageability of the switch and making the network management-based switch to provide integrated and smart management mode, it on one hand simplifies network management procedure, releases the conflict between network scale and network manageability, on the other hand helps user effectively reduce the costs in deployment and maintenance.

10G EPON - Unleashing the Bandwidth Potential
For the first time in history, we can now aim to live in "One World", because the 1st century has ushered in a new era in man's ongoing quest for a better life and a better world. Telco industry is passing through a phase of multiservice revolution, with a shift from legacy to next generation networks and the introduction of new and advanced services (e.g. DTV, HDTV, IPTV, VoIP, WiMAX, Mobile TV, etc.). More and more service providers are progressing to triple-play and even quad-play packages in order to provide a one-stop shopping service to customers. IP traffic is growing exponentially and networks evolve to include bandwidth hungry IP-based applications on voice, video and data. A discussion about broadband medium and speed is on everyone's tongue. But still it is under discussion that 'how fast is fast enough". In fact, broadband is not just a speed it is defined as a potential medium that offers a wide variety of applications to users at their premises. This white paper provides a detailed tutorial overview of the IEEE 802.3av 10Gbit/s Ethernet PON (10G EPON) market trends that are driving the requirement of future last mile access networks, standardization advancements, technology infrastructure.

World FTTX Market
ZTE has the advantage to provide both EPON and GPON technologies. Really involved in the evolution of PON technology, ZTE push the development of PON standards and mainly on interoperability issue. The company also participated in the development of the next generation PON technologies - 10GEPON - and has launched the first prototype last October 2008. 10GEPON will be used to provide greater bandwidth to the final used but will be more and more used combined with VDSL2 in a FTTB architecture.

The strategy of ZTE is therefore to continue their commitment in GPON and EPON (10GEPON) standards.

As already mentioned, ZTE is today leading FTTx market. Furthermore the fact that ZTE won the largest share in China Unicom's group purchase in 2009 Q2, is confirming this leadership.

FTTx Solution White Paper
Fiber access is one of the most important technologies in the next generation network. It increases the access layer bandwidth and builds a sustainable-development access layer network. OAN (Optical Access Network) adopts technologies: active point-to-point (P P) Ethernet and passive optical network (PON).

At the earlier stage, P P adopted dual Tx and Rx fibers to the user. The fiber layout in pairs was difficult. With the development of wavelength division multiplexing (WDM), now in the PON technology, one fiber to the user has been realized. In the downstream direction, the wavelength is 1490 nm, and in the upstream direction, the wavelength is 1 10 nm. PON is the optical access technology developed to support P MP (Point-to-Multi-Point) applications.

Great Achievements in a Small World - An Analysis of WiMAX Indoor Coverage Solution
Indoor coverage is the main battlefield for high density and differentiation among operators, especially for WiMAX. On the one hand, because of the spectrum characteristics of WiMAX, where currently in the world, major spectrums of WiMAX include 2.3G , 2.5G and 3.5G, and the fact that the higher the frequency band, the greater the propagation loss and penetration loss of radio wave in the free space, so as compared with 2G/3G network, WiMAX outdoor base stations have greater difficulty in solving indoor coverage. On the other hand, according to the statistics of NTT DoCoMo, although indoor coverage accounts for only 20% of all covered area, over 70% of data service, especially high speed data service, occurs indoor, so indoor coverage is decisive to network quality.

Overview of SDR Market
With the growing number of access technologies and air interfaces, mobile operators are faced with the daunting task of carefully deploying current networks but also maintaining compatibility with future standards that have not yet entered the market. In developed markets in particular, mobile operators may be faced with radio infrastructure lifecycles of a few years, making it extremely hard to secure Return on Investment (ROI) for newly deployed equipment since marketing and user adoption always lags technology upgrades. Nevertheless, mobile operators follow predetermined technology evolution paths － including GSM to WCDMA to HSPA to LTE － but as technologies evolve, existing hardware that has not been designed for future upgrades has to be replaced or additional overlays need to be added. Especially with LTE which aims to change the air interface from CDMA to OFDM, existing equipment may have to be completely replaced.

Electro-optical cross connection "inducing" higher value
As telecoms networks are in the shift to be packetized and broadband-based, All-IP has been the future development trend of service networks. According to prediction, bandwidth is expected to grow at an annual rate of over 30% in the next five years. The two-layer networking mode "IP over WDM" is gradually replacing the traditional three-layer "IP over SDH over WDM" mode at both backbone layer and metro layer, and the flat architecture enabling carriage of IP packets directly over photonic layer has been an inevitable trend. IP over WDM networking architecture poses new requirements for photonic layer WDM equipments, and WDM layer will take over the networking, service grooming and end-to-end circuit monitoring and management functions originally provided by SDH networks.
