Embodiment Construction

[0055] The basic idea of ​​the present invention is: UE accesses the network, and sends a connection request carrying user location information to ANDSF; ANDSF selects a gateway according to the user location information.

[0056] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0057] The invention provides a method for selecting a gateway, Figure 4 It is a schematic flow diagram of the method for realizing the gateway selection in the present invention, such as Figure 4 As shown, the method includes the following steps:

[0058] In step 401, the UE accesses the network, such as the 3GPP core network, and establishes a connection to the P-GW or PDG or GGSN.

[0059] Step 402, UE sends a connection request carrying user location information to ANDSF;

[0060] Specifically, the UE sends a connection request to the ANDSF to initiate a connection to the ANDSF to obtain WLAN access network ...

Abstract

The invention discloses a method for selecting a gateway. The method comprises the following steps that user equipment (UE) accesses into a network, and transmits a connection request which carries with user location information to an access network discovery and selection function unit (ANDSF); and the ANDSF selects the gateway according to the user location information. The invention also provides a system for selecting gateway. According to the technical scheme disclosed by the invention, the ANDSF can select an access gateway for the UE according to the user location information which is supplied by the UE.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for selecting a gateway. Background technique [0002] An interactive wireless local area network (I-WLAN, Interworking Wireless Local Area Network) refers to a wireless local area network (WLAN, Wireless Local Area Network) access network that interacts with the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) network (AN, Access Network). The I-WLAN is mainly composed of a WLAN, a wireless local area network access gateway (WAG, WLAN Access Gateway), a packet data gateway (PDG, Packet Date Gateway) and other supporting nodes. The purpose of the interaction is to enable the WLAN access technology to cooperate with the 3GPP core network infrastructure to ensure that WLAN users can access the packet services of the 3GPP access network through the WLAN access network. [0003] The general packet radio service (GPRS, General Packet Radio S...
