Network access processing method and user equipment

Abstract

The invention provides a network access processing method and user equipment. The method includes that the user equipment (UE) accesses to a first visit public land mobile network (VPLMN) through a first access network and accesses to a second VPLMN through a second access network; the UE finds and selects strategies of a functional entity of an ANDSF (Access Network Discovery And Selection Function) and one of strategies of an ANDSF of a second VPLMN according to an access network of the first VPLMN to determine to initiate a data flow diversion operation; and the UE performs the data flow diversion operation according to the ANDSF strategies of the first VPLMN and the ANDSF strategies which is different from the ANDSF strategies used for determining the initiation of the data flow diversion operation in the ANDSF strategies of the second VPLMN. The network access processing method and the user equipment effectively ensure that the UE can cooperatively achieve the flow diversion operation of the data flow between 3GPP (the 3rd Generation Partnership Project) access networks and WLAN (Wireless Local Area Network) access networks of different VPLMNs according to different ANDSF strategies after receiving the ANDSF strategies sent by different VPLMNs in a roaming scenario, so that the utilization rate of network resources is improved and the network congestion is reduced.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a network access processing method and user equipment. Background technique [0002] With the development of mobile communication network (standardized by the 3rd Generation Partnership Project (3GPP), referred to as 3GPP network) and wireless local area network (Wireless Local Access Network, referred to as: WLAN), the two networks The intercommunication and integration among them are getting more and more attention from operators. In order to realize the intercommunication and integration of 3GPP access network and WLAN access network, the 3GPP standards organization stipulates the standard for the intercommunication between 3GPP access network and WLAN access network, and defines the access network discovery and selection functional entity (Access Network Discovery and Selection Function abbreviation: ANDSF). ANDSF provides the access network discovery ...
