Description
一种实现多制式协同业务分流网络选择的方法及终端
技术领域 本发明涉及无线通信技术,尤指一种实现长期演进( Long Term Evolution, LTE ) 、 无线局域网络(Wireless Local Area Networks, WLAN ) 、 第三代移 动通信( 3rd-Generation, 3G )的多制式协同业务分流网络选择的方法及终端。
背景技术
随着移动网络的不断演进及 WLAN热点的广泛部署, 一方面, 3G (包括 高速分组数据 (High Rate Packet Data, HRPD ) 网络、 通用移动通信系统 (Universal Mobile Telecommunications System, UMTS)等 )、 LTE和 WLAN等 网络在实际应用中长期共存, 无线接入网呈现异构化的发展趋势; 另一方面, 智能终端的普及和发展使移动互联网用户数量和数据流量也相应的不断增 长, 技术进步也使终端具备接入多个接入网的能力。 因此, 确保用户在合适 的时间、 合适的地点使用最合适的接入网, 以保证用户获得最优的网络应用 体验以及保证网络资源的合理利用是需要关注的问题。 在相关技术中, 当 LTE、 3G和 WLAN网络共存时, 终端在 LTE与 3G 之间的 traffic steering和 offloading由 LTE基站或 3G基站触发, 而 LTE与 WLAN, 或者 3G与 WLAN之间的 traffic steering和 offloading由终端自行触 发。 目前, LTE基站触发的 LTE到 3G间 traffic steering和 offloading和 3G基 站触发的 3G到 LTE间 traffic steering和 offloading没有考虑到 WLAN的网络 状态; 而 UE触发的 LTE与 WLAN或 3G与 WLAN之间 traffic steering和 offloading也没有考虑 3G或 LTE的网络状态。 由于进行业务迁移触发属于不 同的控制点及现有的没有多种制式之间的协同处理机制影响了无线网络资源 的有效利用, 无法按照网络资源状况进行最优的网络选择, 影响了用户的网 络访问体验。 以 LTE为主导的 LTE、 3G和 WLAN共存或重叠覆盖的异构网络为例, 当 LTE有卸载需求时, UE的无线访问业务有可能被迁移到 3G或 WLAN。
LTE基站可以配置终端进行 3G测量,如果 3G信号条件和负载情况满足条件, LTE基站可以触发将终端从 LTE 迁移或重定向到 3G; 由于终端同时处于 WLAN覆盖范围, 终端根据 WLAN网络状态(如: 信号、 负载、 资源情况)、 运营商策略(如 ANDSF 策略) 以及用户选择倾向等可自行触发将业务迁移 到 WLAN。图 1为相关技术的分流决策冲突示意图,如图 1所示,由于 WLAN 和 3G的分流决策点不同以及在分流决策时没有考虑其他网络状态, LTE的 分流决策和终端自行的分流决策和分流操作可能造成冲突, 可能导致 LTE触 发的向 3G 的迁移或重定向无法起到卸载或提升用户体验的目的; 如果釆用 UE自行迁移, WLAN网络容量有限,如果大量的 UE涌入, 容易导致 WLAN 用户体验恶化。
基于目前 3G 网络在满足用户普通上网需求方面已经能够提供比较好的 用户体验, 需要一种支持 LTE、 3G、 WLAN的多制式协同的网络选择, 以提 供给用户更优的网络应用体验, 及各科学合理的网络资源使用。 相同的, 当 3G网络有卸载需求时, 业务有可能被卸载到 LTE或者是 WLAN, 影响用户 体验的决策冲突依然存在, 无法提供最优质的无线网络资源。
综上所述, 目前在 3G、 LTE、 WLAN的网络之间进行业务迁移, 缺少一 种多制式协同的网络选择方法,影响了用户充分利用现有环境中的网络资源, 实现无线业务的良好访问。
