Still in the exploratory stage to introduce strategies HSPA
As an enhanced version of 3G, HSPA (High Speed Packet Switching Technology) of the mobile communications industry has been subject to wide attention. In the global perspective, there are 123 HSDPA (High Speed Downlink Packet Switching) network in 56 countries and regions have plans to deploy, 70 HSDPA networks have commercially in 39 countries. Currently, HSPA is also sought after by many communications equipment manufacturers, HSPA maturity of technologies and products are often considered to be manufacturers in the 3G field strength evaluation criterion. Recently, in “The Second HSPA technology development strategy will be high-level consultation”, a large number of domestic communication industry experts outlook released HSPA as well as the introduction of HSPA in the Chinese business strategy and environmental analysis.
HSPA access to opportunities in China?
In China, although the issuance of 3G licenses is still in very uncertain times, but the four major domestic carriers are already making active preparations. For example, China Mobile has joined in September of this year in the United Kingdom established NGMN (Next Generation Mobile Communications Network) organization, hopes to combine market insights of next generation network needs to provide clear systemic goals, to the ISO, for each chain standardization of production processes for next generation network to carry out clear guidance. It is understood that the 7 was launched in NGMN operators, China Mobile and outside addition to already have their own 3G networks. China Telecom and China Netcom have also set up a 3G-related research, in actively exploring the introduction of 3G and HSPA strategy.
3G development in China lags behind in the communications industry to bring anxiety, but also gives an opportunity to HSPA.?????????????????????????????????????????G??????????????SPA????????????????????SPA?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????

HSPA network strategy with business change
Strategy on the introduction of HSPA, operators are still at an exploratory stage, did not explicitly propose HSPA position in the 3G era and network formation. This is a technical problem, but it is a market problem. At present, 3G and HSPA network primarily in the hybrid network and each independent network of two ways.
In the hybrid network which, taking into account the existing R99 systems to be compatible with the planning and design, will have the power allocation and code allocation of resources, which is currently the majority of operators in the design and planning of the difficulties to be resolved and priorities.???????????????????????????????????SDPA?????????????????????????????????????????????????????????????????????????????????????????br />
He told reporters that the static power allocation is mainly the corresponding region in advance of the average data throughput for statistical, estimated the number of HS-PDSCH channel and the corresponding power resources, and then in the OMC configuration, you can adjust, but adjust the frequency is not high; and dynamic power allocation as the proportion of current users is difficult to predict, to achieve the precise power ratio is very difficult, in order to avoid irrational use of power configuration lead to waste of power, while the introduction of dynamic allocation of power resources. However, the distribution of power and code resources, relations and also as the two formats investments and earnings per bit set, a more complex process.
Two independent network format is not compatible to consider the problem exists, but due to the different scenarios, the hybrid network also need to create and design model between the business market.???????????????????????????????????????????????????????????????HSDPA??????????????????????????????????????????????????SDPA??99??????????????????????????????????????SDPA??99??????????????????????????????????°?
??????????????????????????????????????????????????G??????????????????????????????????????????????????????????????????????????????HSDPA??????????????????????????????????????????????????????????????????HSDPA??????????????????????????????????????????????????????????????????????????????????????????????????????????????? We must take a different time to introduce a different strategy for HSDPA, the change in the data business to set different frequencies and the introduction of different networks.
Cao Lei to reporters that, the current operating companies to do the work to be done Henduo, ongoing and needs of Jin Xing's experiments and exploration, Zhu Yao You three Fangmian: Complete Yinru HSUPA, HSDPA upgrade for Baokuorenkou Mijishiqu, suburban and other environments in the coverage, throughput, switch, delay and other indoor and outdoor tests; of HSDPA / HSUPA (high speed uplink packet switching technology) technical characteristics and business carrying capacity; of how to deal with HSDPA / HSUPA and R99/R4 networking, such as business hosted differences, the relationship between network coverage, wireless resource allocation.
TD-HSDPA upcoming commercial products
In China, due to the licensing of 3G TD-SCDMA associated with the great, the TD-SCDMA, HSPA technology development has been the concern of many experts. Jian-qiu has said that as TD-SCDMA is very suitable for the unique technical features of the future of limited spectrum resources, network expansion and support of different business, the most important is its strong support by the Chinese government and to adapt to HSPA, so the future 3G development it is very competitive.

During this consultation meeting, Lee Road, also on behalf of Datang Mobile announced to the industry, Datang Mobile will be on November 15 officially released single-carrier based on TD-HSDPA commercial version of the product to be launched next year, based on multi-carrier HSDPA products.??????????????D-HSDPA???1Mbps??????????????????????????2???????????????????????
????????????????????????????????CDMA??DMA2000?????D-SCDMA??D-HSDPA????????????????????????????????Part of the TD-SCDMA operators there is concern reasonable. Wu Xingyao said that operators need to target a mature network, rather than the TD-SCDMA standard to meet or exceed the same network at the same time period indicators. Some experts also pointed out that the current TD-SCDMA commercial networks also need to address a variety of formats to exchange 3G standards in large data exchange scenarios to deal with the details of the upcoming Olympic Games and other major conferences of the communication of unexpected problems.
