Embodiment 1

[0071] The scenario of this embodiment is that the WLAN is connected to the EPC network through the ePDG as an untrusted 3GPP, and the S2b interface is used between the ePDG and the P-GW. The specific process of this embodiment is as figure 2 Shown:

[0072]Step 201, when a user terminal accesses through a WLAN which is an untrusted 3GPP access network, it needs to perform access authorization and authentication with the AAA Server of the core network. The role of AAAproxy is to forward the authorization authentication message to the AAA Server. After the access authorization and authentication process, the user is allowed to access the core network through the WLAN.

[0073] Step 202, the user terminal monitors the routing area identity (Routing Area Identity, RAI) or location area identity (Tracking Area Identity, TAI) in the broadcast message of the 3GPP UTRAN or E-UTRAN network covering the same coverage as the WLAN access network.

[0074] In step 203, the user termin...

Embodiment 2

[0089] The scenario of this embodiment is that the WLAN is accessed as an untrusted 3GPP, accesses the EPC network through the ePDG, and uses the S2c interface between the user terminal and the P-GW. The specific process of this embodiment is as image 3 Shown:

[0090] Step 301 , when a user terminal accesses through a WLAN that is an untrusted 3GPP access network, it needs to perform access authorization and authentication with the AAA Server of the core network. The role of AAAproxy is to forward the authorization authentication message to the AAA Server. After the access authorization and authentication process, the user is allowed to access the core network through the WLAN.

[0091] Step 302, the user terminal listens to the RAI or TAI in the broadcast message of the 3GPP UTRAN or E-UTRAN network covering the same coverage as the WLAN access network.

[0092] Step 303, the UE constructs the FQDN for ePDG selection and / or the FQDN for P-GW selection according to the re...

Embodiment 3

[0105] The scenario of this embodiment is that the WLAN is accessed as a trusted 3GPP, and the S2c interface is used between the user terminal and the P-GW. The specific process of this embodiment is as Figure 4 Shown:

[0106] Step 401 , when a user terminal accesses through a WLAN that is an untrusted 3GPP access network, it needs to perform access authorization and authentication with the AAA Server of the core network. The role of the AAA proxy is to forward the authorization authentication message to the AAA Server. After the access authorization and authentication process, the user is allowed to access the core network through the WLAN.

[0107] Step 402, the user terminal listens to the RAI or TAI in the broadcast message of the 3GPP UTRAN or E-UTRAN network covering the same coverage as the WLAN access network.

[0108] Step 403, the user terminal constructs the FQDN used for P-GW selection according to the received RAI or TAI.

[0109] Step 404, the user terminal...

Abstract

The invention discloses a gateway selection method, implementation equipment and system, which are used to solve the technical problem that the gateway selection based on the user location cannot be realized when the mobile network operator moves the data plane gateway downward, thereby realizing WLAN network data distribution . In the present invention, the user terminal constructs the FQDN of the evolved data gateway ePDG and / or the FQDN of the packet data gateway P-GW according to the identification information in the wireless network broadcast message, thereby triggering DNS query of the ePDG and / or P-GW close to the wireless side , thereby realizing the offloading function of data in the WLAN network.

Description

technical field [0001] The present invention relates to the field of mobile communications, in particular to a method for selecting a gateway close to a user side in a wireless local area network (Wirless Local Area Networks, WLAN) network in a user service data offloading scenario, and a device and a system for realizing the method. Background technique [0002] In order to maintain the competitiveness of the third-generation mobile communication system in the communication field, provide users with faster rate, lower delay, and more personalized mobile communication services, and at the same time reduce the operating costs of operators, the third-generation partner A standard working group of a 3rd Generation Partnership Project (3GPP) is working on research on an Evolved Packet System (EPS). figure 1 A schematic diagram showing the structure of an evolved packet domain system, such as figure 1 As shown, the entire EPS system is divided into two parts, the wireless access...
