【文章內(nèi)容簡介】 84kbps ServicesBesides downlink rate that Huawei HSDPA solution can provide, Huawei also introduces enhanced solution to support 384k in both downlink and uplink, which can support symmetrical services such as high quality video phone, video conference and high speed for upload applications with large traffic, such as ftp and P2P file sharing.第四節(jié) 展臺(tái)設(shè)備介紹 UTRAN for Better Coverage and Higher Performancea) Huawei delivers plete set of NodeB family, meeting different needs of operators. These include the 12TRX/6TRX indoor macro NodeB, the 6TRX outdoor macro NodeB, the allinone Mini NodeB, and the distributed NodeB (Baseband Processing Unit (BBU) and the Remote Radio Unit (RRU))。b) Distributed NodeB, which can greatly reduce OPEX and CAPEX, Separate traditional macro Node B into two parts: BBU and RRU connecting via optical fiber. The interface between RRU and BBU is open, according to CPRI, Huawei is one of the founders of CPRI. For details, please refer to .c) For the initial deployment of 3G network, the coverage is most concerned by operators. With Huawei’s optimal coverage solution, the coverage of UMTS can be as good as that of GSM 900MHz system. These technologies include: power bining with TX diversity, high RX sensitivity of 125dBm, RRU and Tower Mounted Amplifier, 4way RX diversity, AMR Control and DCCC RRM algorithms, etc.d) The efficiency of traditional LPA is 9%, based on FF technology. Huawei developed new PA technology, DP(Digital PreDistortion) plus HPA, which enhance the power efficiency to 18%.e) Huawei has also developed enhanced RTT algorithms that can ensure both coverage and capacity in the future. These include the Smart Antenna, the MultiUser Detection, etc.f) The bearer capability of Huawei NodeB is very remarkable. It can simultaneously support up to 8 connections of 384Kbps on the downlink and 7 connections of 384Kbps on the uplink within one single sectorcarrier.g) Huawei HSDPA can support 15 codes and full rates up to , relies on selfdesigned ASIC chip.

It realizes the separation of carrier and control, featuring smooth evolution, convenient Oamp。M, flexible rollout and control of services.b) Huawei R4 Core Network supports simultaneous access of both UTRAN and GSM BSS, and also has backward patibility with 3GPP Rel99. So we call it a unified core network solution.c) The MSC Server and MGW feature large capacity, high density and highscalability. They both have pact configuration of one single rack, supporting 50,000 subscribers to the minimum. Due to the modular design, they can be expanded all the way to their full capacity, . million subscribers with 3 racks.d) The Video Interworking Gateway (VIG) is a very important network element for the realization of mobile video services. It functions as the interpreter for signaling between systems based on different video standards, . and , enabling the interconnection of video services between UMTS and other tele systems, . NGN, broadband, Internet.e) Huawei adopts enhanced technologies to improve the quality of voice service, including TFO/TrFO, AMR Control, Comfortable Noise Generation, and Loss Packet Compensation.f) Huawei’s CS CN products have been widely deployed in the mercial network of China, Thailand and .
