Description

一种分流的方法及装置 技术领域
本发明涉及通信技术领域,特别涉及一种分流方法及装置。
背景技术
随着用户需求的增长和通信技术的发展,无线通信技术和相关网络的种类也更多,例如,有可以提供广覆盖的2G/3G/4G移动通信技术及网络、可以提供热点覆盖的Wifi(Wireless Fidelity,无线保真)技术和WLAN(Wireless Local Area Networks,无线局域网)。因此也大量出现了不同的通信网络共存的场景,如2G/3G/4G网络和WLAN共存的场景。
EPS(Evolved Packet System,演进的分组***)***是一个支持多种接入技术和多种接入间移动性的***。在多接入场景下,终端可能处于多个3GPP(3rd Generation Partnership Project,第三代合作伙伴计划)和/或非3GPP接入网络的共同覆盖下。这些接入网络可能使用不同的接入技术,可能属于不同的运营商,也可能提供到不同核心网的接入。UMTS(Universal Mobile Telecommunications System,通用无线通信***)/LTE(Long Term Evolution,长期演进)和WLAN网络共存场景如图1所示,在UMTS/LTE的基站(UMTS中的Node B,LTE中的eNB)覆盖范围内,存在多个WLAN的AP(Access Point,接入点)。接入点的覆盖范围相对基站来说比较小。
在上述场景下,目前已经支持的一种UMTS/LTE和WLAN互操作的网络架构,该架构是基于PDN Gateway(Packet Data Network,分组数据网络网关)和UE之间的S2c接口来实现互操作的。现有技术中,均采用的是基于终端(UE based)的方案来实现UMTS/LTE和WLAN之间的互操作。
随着智能终端以及移动应用的迅速发展,移动数据流量剧增,导致现网越来越难以满足数据流量增长的需求。因此,为了缓解目前3GPP网络的流量负荷,移动运营商希望借助于non-3GPP网络来承载部分3GPP网络的流量。
目前,终端在进行切换时,切换后,目标基站从目标基站下可以进行业务分流的AP中选择出目标AP,并将目标AP的信息发送至终端,由于终端切换后,终端在源基站下的业务中断,目标基站将目标AP的信息发送至终端后,终端才能接入目标AP,恢复业务,业务中断时间较长,这样,就存在业务的连续性较差,业务质量较低的缺陷。
