上海移动TD网络目前已经完成了与2G网的初步融合。TD网络的业务尤其是数据业务不断增加,用户也同样处在不断发展的过程中。但TD网络目前与2G网络的质量相比有一定差距,除去终端成熟的因素,网络质量在一定程度上影响了TD用户与业务的发展,尤其TD/2G重选时延长导致用户无法主被叫已成为影响话音业务用户感知最主要的因素。因此TD网络今后工作中的一部分重点在于不断通过各种解决手段来提高网络的质量与能力,推进2G/TD网络的深度融合。本文拟从2G/TD共LAC组网应用探讨以下两方面的研究:1)2G/TD无线网络融合的技术解决手段,Iurg+、TD/2G切换问题;2)探讨随着2G/TD双模终端比例不断提高和两网融合度的不断提升对无线网络资源配置所造成的影响问题。
Shanghai Mobile TD network has now completed a preliminary integration with the 2G network. TD network business, especially data services continue to increase, users are also in the process of continuous development. However, there is a certain gap between the quality of the TD network and that of the 2G network. Apart from the maturity of the terminal, the network quality affects the development of TD users and services to a certain extent. In particular, when the TD / 2G reselection is prolonged, the user can not call the called party Has become the voice of the user experience has become the most important factor. Therefore, TD network in the future part of the focus of work is to continue through various means to improve the quality and ability of the network to promote the depth of 2G / TD network integration. This paper intends to explore the following two aspects from the application of 2G / TD LAC networking: 1) the technical solution of 2G / TD wireless network convergence, Iurg +, TD / 2G handover; 2) The increasing proportion of the network and the continuous improvement of the convergence of the two networks have caused problems of the wireless network resource allocation.
