Research On Separating The GSM Network Using TD-SCDMA And Enhancing The Utilization Rate Of The Code Resource

With the development of mobile Internet and the popularity of intelligent terminals, mobile data business diversification, data service and data flow are obtained the swift and violent growth. At present, the national average (TD-SCDMA cyber source utilization rate of the index is to determine the network busy degree important basis)(Time Division-Synchronous Code Division Multiple Access) of less than10%, T net to absorb the traffic situation is not ideal, can not effectively share GSM network load, thus causing the GSM network utilization rate rises rapidly, has more than70%warning threshold, the network load increasing. Therefore, the rapid growth of data traffic is on the GSM (Global System of Mobile communication) cyber source caused by the huge influence and the impact.How to reduce the network load, reduce the GSM TD user business flow, improve the proportion of TD network code resource utilization and shunt ratio has become the urgent problem to solve. This article on the TD reflux cause from the operating data,2/3G interoperability parameter settings, TD network coverage, user behavior problems were analyzed, and aimed at these reasons from system mutual operation setting, parameter optimization, terminal and marketing aspects and puts forward the corresponding strategies and solutions.In order to make the T net share g load, we need to improve the TD network" hard cover" and" soft cover " capability, the so-called" hard cover" namely promotion broadcast channel PCCPCH (Primary Common Control Physical Channel)transmit power, effectively increasing the TD network coverage. The so-called" soft cover" that fine adjustment2/3G reselection and switching parameters (focus on the2/3G interoperability frequent region), to promote TD terminal" go back to the late", effective residing in T network. Through the optimization of the network, network parameters more reasonable. At the same time, synchronized resource coordination optimization, each district are equipped with R4and HSDPA (High speed downlink packet access)carrier, to ensure that the two types of carrier ratio is more reasonable, to meet the different needs of voice and data service, data service priority load in HSDPA carrier, to enhance the user’s perception. In the conditions allow, the timely introduction of some new function, ensure that TD shunting effect.To me province Jinzhou as experimental area, by adopting the shunting means, days for units to adjust the effect were compared before and after verification, TD code resource utilization by adjusting the previous6.15%to8.11%, traffic and data traffic is separately from the optimization before3696Erl,23GB to5328Erl,37GB, promotion effect apparent.
