WLAN terminal, base station and switching control method from LTE network to WLAN network

Abstract

A WLAN terminal, a base station and a switching control method from an LTE network to a WLAN network are disclosed. The method comprises the following steps of when receiving a switching request sent by a base station, analyzing identification information of user equipment; sending the identification information of the user equipment to an attributive signed user server HSS through an AAA server so that the attributive signed user server HSS carries out authentication on the user equipment so as to generate authentication information of the user equipment, and the AAA server generates corresponding authentication association information based on the authentication information; when the authentication association information sent by the AAA server is received, storing the authentication association information; when user equipment access is determined, sending the authentication association information to the user equipment so that the user equipment uses the authentication association information to access the WLAN network. In the above scheme, time of authentication access in a process of switching from LTE to WLAN can be saved, and a user experience is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a switching control method from a WLAN terminal, a base station and an LTE network to a WLAN network. Background technique [0002] Long Term Evolution (LTE) and wireless local area network (Wireless LAN, WLAN) aggregation (LTE-WLAN Aggregation, LWA), is when the user equipment (ie UE Termination, referred to as UE) is in the radio resource control connected state (RRC Connected) It is configured by the base station to simultaneously use the wireless resources of LTE and WLAN for data transmission. At this time, the user equipment maintains an RRC connection with the base station in LTE, and the base station is responsible for transmitting the non-access stratum signaling of the user equipment (uplink non-access stratum signaling The base station sends the signaling to the core network, and the downlink non-access stratum signaling is sent to the user equipment by ...

AI Technical Summary

Problems solved by technology

The authentication process requires multiple interactions between the UE and the AAA server (including HSS), which will take a long time, resulting in the PDN connection establishment process initiated by the UE in the WLAN (the PDN connection that has been established in LTE) will take a long time. Time, so that the business interruption time is longer, affecting the user experience
