Description

一种在不同制式网络间进行重选的方法及终端 技术领域
本发明涉及通信技术领域, 尤其涉及一种在不同制式网络间进行重选 的方法及终端。 背景技术
随着第三代(3G, 3rd-Generation )移动通信时代的到来以及 3G 网络 例如时分同步码分多址 (TD-SCDMA, Time Division- Synchronous Code Division Multiple Access )网络的逐渐成熟 , TD-SCDMA的用户数稳步增长, 分组交换 ( PS, Packet Switching ) 业务的需求即将迎来爆发式的增长。 可 是, 3G用户的增加并没有给 TD-SCDMA网络带来大的网络流量, 反而使 得 2G 网络例如全球移动通讯系统 (GSM , Global System of Mobile communication ) 网络的业务负荷几近达到饱和。 究其原因, 是因为目前 TD-SCDMA的网络覆盖还不够完善, 网络建设和终端技术还需要进一步提 高。按照第三代合作伙伴计划( 3GPP, The 3rd Generation Partnership Project ) 的技术标准规范, 终端在选定一个网络后, 业务会在该网络下进行, 然后 根据在异制式的测量结果以及网络的指令做系统间的重选。 由于 TD-SCDMA的网络覆盖不全, 再加上目前的网络和终端对 2G、 3G互操作 的支持性都不太好, 用户在移动过程中, 哪怕是静止状态, 都可能发生频 繁的系统间重选。 这就导致 TD-SCDMA 用户的用户体验非常差。 TD-SCDMA用户选择 3G是希望享受先进通信技术提供的高带宽数据业务, 他们往往都有高速数据业务的需求。 而频繁的 2G、 3G重选后使得数据业 务往往都是在 GSM完成, 有些用户无法忍受 3G的频繁脱网干脆将手机锁 定在 GSM网络。 于是, TD-SCDMA用户增加的大数据流量主要落在了带 宽较小的 GSM网络上,使得 GSM网络负荷基本达到饱和, 而 TD-SCDMA 网络却几乎为空。
由此可见, 现有技术中存在问题主要是 2G、 3G 网络负荷不均衡的问 题。 发明内容

本发明实施例提供的方案, 由于通过终端控制使得高速 PS业务在 3G 网络进行, 实现将高速 PS业务从 2G网络分流到 3G网络、 均衡 2G、 3G 网络负荷的目的。 附图说明
图 1为本发明实施例提供的在不同制式网络间进行重选的方法流程图; 图 2 为本发明实施例提供的在不同制式网络间进行重选的终端的结构 示意图。 具体实施方式
下面结合附图对本发明实施例的技术方案进行详细说明。
为了解决现有技术中 2G、 3G网络负荷不均衡的问题, 本发明实施例, 提供一种在不同制式网络间进行重选的方法,本实施例中以 GSM网络作为 2G的网络的优选方案来进行说明, 以 TD-SCDMA网络作为 3G的网络的 优选方案来进行说明, 当然 2G也可以是码分多址( CDMA, Code Division Multiple Access ) IX网络, 3G网络也可以是宽带码分多址( WCDMA, Wideband Code Division Multiple Access )和 CDMA2000。 为了解决现有技 术中 2G、 3G网络负荷不均衡的问题, 本实施例的方案的基本思想是:
首先终端在驻留在 GSM网络的情况下,判断当前单一业务是否为高速 PS业务; 判定为是时, 终端在 TD-SCDMA网络可用的情况下, 直接重选 到 3G网络进行高速 PS业务处理。
本实施例的方案通过终端控制使得高速 PS业务尽量在 3G网络进行, 实现将高速 PS业务从 2G网络分流到 3G网络、 均衡 2G、 3G网络负荷的 目的。
本实施方案提供的一种在不同制式网络间进行重选的方法, 如图 1 所 示包括:
步驟 101: 开机即优先在 GSM网络驻留。
步驟 102: 接收单一业务请求并判断是否是电路交换 (CS , Circuit Switching )业务请求, 如果是 CS业务请求, 则执行步驟 107; 否则, 执行 步驟 103。 步驟 103: 判断单一业务请求是否为高速 PS业务请求, 如果否, 则确 定有低速 PS业务请求, 执行步驟 108; 如果是, 则执行步驟 104。
步驟 104: 在 TD-SCDMA网络满足业务接入条件的情况下将终端直接 重选到 TD-SCDMA网络。
步驟 105: 在 TD-SCDMA网络进行高速 PS业务处理。
步驟 106: 高速 PS业务结束后忽略网络设定的重选条件, 直接重选到 GSM网络, 之后执行步驟 109。
步驟 107: 按照预定的策略进行相应的 CS业务请求处理, 业务结束后 执行步驟 109。
步驟 108: 按照预定的策略进行相应的低速 PS业务请求处理, 业务结 束后执行步驟 109。
步驟 109: 在 GSM网络下驻留。
在步驟 101中, 终端的应用环境是在 GSM网络中, 当终端开机后, 若 同时发现 GSM网络和 TD-SCDMA网络, 则终端驻留在 GSM网络, 同时 终端还要进行 TD-SCDMA 小区的测量, 以备后续步驟中如果需要重选到 TD-SCDMA小区时, 为是否能重选到 TD-SCDMA小区提供依据。 在本步 驟中终端开机后在待机状态下, 若 GSM网络信号和 TD-SCDMA网络信号 同时存在, 是优先要驻留在 GSM网络。
在步驟 102中, 终端收到单一业务请求后, 先要判断是否是 CS业务请 求, 如果发现当前收到的单一业务请求是 CS业务请求, 执行步驟 107, 终 端会按照预定的策略进行相应的 CS 业务请求处理, 例如选择继续驻留在 GSM网络进行上述的 CS业务, 并在 CS业务完成后执行步驟 109继续在 GSM网络驻留。 CS业务请求可以是准备接听语音呼入、准备进行语音呼出、 准备发送短信或者是准备接收短信中的一种时, 当然本实施例中不对 CS业 务的范围进行限定,即不限定 CS业务仅包括接听语音呼入、进行语音呼出、 发送短信或者是接收短信。
在步驟 103中,终端判断收到的单一业务请求是否是大数据量的 PS业 务, 例如判断是否是 internet网页浏览、 ftp文件传输、 流媒体或视频点播 业务中的一种, 若收到单一业务请求后, 确定不是上述的业务之一, 则确 定是低速 PS, 在 GSM进行。
当然本实施例中不对高速 PS业务的范围进行限定, 即不限定高速 PS 业务仅包括上述的 internet网页浏览、 ftp文件传输、 流媒体、 视频点播业 务,本实施例中的高速 PS业务是相对于低速 PS业务而言的, 高速 PS业务 是仅能在 3G网络中进行处理, 不能在 2G网络中进行处理的 PS业务, 低 速 PS业务是既能在 3G网络中进行处理, 又能在 2G网络中进行处理的 PS 业务, 一般的理解如 GPRS/EDGE是低数据量的 PS业务( 100K左右)。
在步驟 104中, 在有高速 PS业务请求的情况下, 如有 ftp文件传输请 求, 终端会判断当前的 TD-SCDMA网络满足业务接入条件, 例如根据之前 对 TD-SCDMA小区的测量, 当前终端接收的 TD-SCDMA网络信号强度大 于设定的阈值 A, 则确认当前的 TD-SCDMA网络满足业务接入条件, 或者 当前终端接收的 TD-SCDMA网络信号的 QOS大于设定的阈值 B, 则确认 当前的 TD-SCDMA网络满足业务接入条件,当然还可以设定其它的接入条 件, 如终端已经经过 TD-SCDMA网络的预认证等等, 本实施例中不对此进 行限定,具体实施时可以根据具体的应用需求对 TD-SCDMA网络业务接入 条件进行设定。 无论 TD-SCDMA网络业务接入条件是什么, 只要满足该条 件且当前单一业务请求为高速 PS业务请求, 则直接重选到 TD-SCDMA网 络, 此处不必考虑网络设定的重选条件, 如网络设定的重选条件为 TD-SCDMA网络信号强度大于 GSM网络信号强度,此时即使 TD-SCDMA 网络信号强度小于 GSM网络信号强度, 但只要满足 TD-SCDMA网络业务 接入条件则直接进行重选。 通过上面的步驟, 对单一业务请求时的业务处理流程进行了说明, 通 过终端控制使得高速 PS业务在 3G网络进行,使得低速 PS业务和 CS业务 在 2G网络进行, 实现将高速 PS业务从 2G网络分流到 3G网络、 均衡 2G、 3G网络负荷的目的。但实际应用中往往是对高速 PS业务进行处理的同时, 会发起 CS业务,此时高速 PS业务和 CS业务则在 TD-SCDMA网络中并发, 在 TD-SCDMA网络并发的情况下如果 TD-SCDMA网络的信号不好满足预 定的重选条件, 则重选到 GSM网络, 此时 CS业务保持, 释放高速 PS业 务。 在 TD-SCDMA网络并发的情况下, 如果 TD-SCDMA网络的信号一直 良好, 则会一直保持在 TD-SCDMA网络中, 之后如果 PS业务结束则 CS 继续保持在 TD-SCDMA网络, CS业务也释放后直接重选到 GSM网络待机。
本发明实施例还提供了一种在不同制式网络间进行重选的终端,如图 2 所示, 包括: 判决模块 201和处理模块 202; 其中,
判决模块 201 , 用于在驻留在 2G网络的情况下, 判断当前单一业务是 否为高速 PS业务, 将判断结果发送给处理模块 202;
处理模块 202, 用于接收判决模块 201发来的判断结果, 若判断结果是 高速 PS业务, 则终端在 3G网络可用的情况下, 直接重选到 3G网络对所 述高速 PS业务进行处理。
进一步, 判决模块 201 , 还用于判断当前单一业务是否为 CS业务, 若 否, 则判断当前单一业务是否为高速 PS业务。
进一步, 判决模块 201 , 还用于若判断当前单一业务是 CS业务, 则继 续驻留在 2G网络进行 CS业务, 若判断当前单一业务不是高速 PS业务, 则确定是低速 PS业务, 继续驻留在 2G网络进行 CS业务。
进一步, 处理模块 202, 还用于在 3G网络进行高速 PS业务处理的情 况下,如果发起 CS业务, 则在 3G网络进行高速 PS业务和 CS业务并发处 理。 进一步,处理模块 202 ,还用于在 3G网络进行高速 PS业务和 CS业务 并发处理的情况下, 若 3G网络信号满足预定的重选条件, 则重选到 2G网 络保持 CS业务以及释放高速 PS业务。
显然, 本领域的技术人员可以对本发明进行各种改动和变型而不脱离 本发明的精神和范围。 这样, 倘若本发明的这些修改和变型属于本发明权 利要求及其等同技术的范围之内, 则本发明也意图包含这些改动和变型在 内。
