Huawei: Winning TD unified platform for the future evolution of the Road
HC communication network "TD's growth rate is unprecedented." This has become a TD builders felt the same way. TD technology continues to change in the spectrum increased period of development, after three of the TD network building process has experienced rapid update TD equipment, network equipment, there is the phenomenon of change too frequently. In this regard, Huawei Wireless China Industry Zhou Jianguo, vice president Marketing, said: "Huawei's current network equipment and 'four' new equipment from the same platform, there is no compatibility issues, also supports smooth evolution to meet the requirements of LTE, it does not exist platform before the change caused by the late replacement of equipment problems. "
Solve problems with channel interference In addition, within the same network for TD-frequency interference, Zhou Jianguo told reporters, Huawei to deliver a total solution can be divided into four categories: first, the physical layer solution for interference suppression class of algorithms, including multi-cell joint inspection and Adaptive power suppression; second, RNC side RRM algorithm solution to avoid interference methods, including DCA and iDCA two, DCA is based on the load cell to load shared equally in the allocation of frequency and time slot resources, IDCA is considering serving cell loads, combined with service residential close adjacent areas corresponding to the load information, a comprehensive compliance assessment; third, interference isolation method that TFFR, is a combination of interference and frequency multiplexing isolation solution; fourth, disturbance approach is the UE has been strong interference, RNC resource adjustment strategies.
Series of innovations to create high-quality TD
China Mobile TD important long-term development of a strategy shall be to encourage innovation, Huawei Group and a number of provinces have also undertaken a series of thematic depth Cooperation . In Sichuan, Sichuan Mobile launched a large-scale cooperation with Huawei, including the GPS clock replacement, F / A / E joint networking, dual-channel indoor coverage, hot spot data service coverage, 2G / 3G Interoperability and network optimization template library to create a number of innovative technologies such as the current network of research and validation, innovation-rich, the first time to the various provinces and cities to share the results significantly, the rapid maturity of the network to promote the TD. Another example is the national network of testing by highly of La Hangzhou, TD network KPI Group challenge-round more than the value of long-term evolution of TD Huawei to support the development of the 1588V2 and IPRAN key technologies such as large-scale network construction is verified that the program security and stability, fully satisfy the networking requirements TD. Enhance the user perception in terms
is re-election to extend the network 2G/3G seriously affect the user perception. Huawei's solution is to wait for the MSC paging, FastReturn, MSCPOOL, a total of LAC, accurate paging, effectively reducing the re-election delay, delay location update and upgrade the switch rate and the paging success rate.
2010, Huawei will continue to cooperate with similar technical innovation. Zhou Jianguo told reporters TD for network expansion project in 2010 on the F / A / E tri-band network and the LTE evolution of requirements, Huawei has launched a broadband technology based on broadband MCPA RRU, simplified form tri-band network equipment to meet are indoor and outdoor multi-frequency network networking scene, and follow-up of dual-mode networking scene, while consuming less power, site problems easier to solve. In particular, dual-channel RRU is Huawei's innovative products, with the dual-channel small Antenna To solve the problem of siting cell depth of coverage. "This year the main focus of innovation to enhance user perceived launched a series of programs, such as coverage increased, the bandwidth upgrade, improve voice quality, 2G/3G integration, in addition to dual-channel RRU Mulch, AUE adaptive uplink enhancement, HSPA control channel 4 times air separation, VQI full drive test statistical quality of the whole network, MOS points to upgrade, Iur-g + fusion. "Zhou Jianguo said.
