Description
本申请涉及但不限于通信技术领域。This application relates to, but is not limited to, the field of communication technology.
随着VOWIFI(Voice over Wireless Fidelity)等业务的飞速发展,以往3GPP(3rd Generation Partnership Project,第三代合作伙伴计划)移动网络的一些业务(如语音业务)飞快的扩展到Non-3GPP(非3GPP)网络上来。With the rapid development of services such as VOWIFI (Voice over Wireless Fidelity), some services (such as voice services) of the 3GPP (3rd Generation Partnership Project) mobile network have been rapidly extended to Non-3GPP (non-3GPP). ) The network is coming.
3GPP网络例如包括:LTE(Long Term Evolution,长期演进)、WCDMA(Wideband Code Division Multiple Access,宽带码分多址)、TD-SCDMA(Time Division-Synchronous Code Division Multiple Access,时分同步码分多址)和GSM(Global System for Mobile Communication,全球移动通信***)网络。The 3GPP network includes, for example, LTE (Long Term Evolution), WCDMA (Wideband Code Division Multiple Access), and TD-SCDMA (Time Division-Synchronous Code Division Multiple Access).

Non-3GPP网络例如包括:WLAN(Wireless Local Area Networks,无线局域网)、HRPD(High Rate Packet Data,高速分组数据)和WiMAX(Worldwide Interoperability for Microwave Access,全球微波互联接入)。The Non-3GPP network includes, for example, WLAN (Wireless Local Area Networks), HRPD (High Rate Packet Data), and WiMAX (Worldwide Interoperability for Microwave Access).
相关技术中,s2b接口应用于非授信域网络和EPC(4G核心网络)之间的互通,WLAN网络通过ePDG(evolutionPacket Data Gateway,演进的分组数据网关)接入PDN GW(Packet Data Network Gateway,分组数据网关),通过ePDG以实现非授信域接入网络和EPC的互通。在s2b模式下进行的切换是基于用户设备的切换,核心网侧不对Non-3GPP网络进行测量,用户设备根据预先设定的切换规则或者根据从网络侧获取的网络信号门限值的测量情况,将业务在3GPP和Non-3GPP网络间进行切换。但是对于非可信的Non-3GPP网络,如WLAN等,用户设备只能得到用户设备到ePDG的情况,对于ePDG到核心网侧的链路质量无法获知,这样,用户设备将无法从全局的角度来选择最优的Non-3GPP网络,因此在切换时,切换成功率难以控制,同时无法保证业务的延续性和质量。
In the related art, the s2b interface is applied to the interworking between the non-trusted domain network and the EPC (4G core network), and the WLAN network accesses the PDN GW (Packet Data Network Gateway) through the ePDG (evolutionPacket Data Gateway). Data gateway), through ePDG to achieve interworking between the non-trusted domain access network and the EPC. The handover performed in the s2b mode is based on the handover of the user equipment, and the core network side does not measure the Non-3GPP network, and the user equipment performs measurement according to a preset handover rule or according to a network signal threshold value acquired from the network side. The service is switched between 3GPP and Non-3GPP networks. However, for a non-trusted Non-3GPP network, such as a WLAN, the user equipment can only obtain the user equipment to the ePDG. The quality of the link from the ePDG to the core network cannot be known. Therefore, the user equipment cannot be viewed from a global perspective. In order to select the optimal Non-3GPP network, when switching, the handover success rate is difficult to control, and the continuity and quality of the service cannot be guaranteed.
