Problems solved by technology

[0004] The inventors found that in the prior art, when the non-3GPP system is connected to the EPC, the MS / UE request additional PDN process and the implementation subject are not clearly defined in the CMIP (ClientMobile Internet Protocol, Client Mobile Internet Protocol) mode, In fact, according to the description of the existing protocol, it is impossible to realize the selection of MS / UE and additional PDN

Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] This embodiment discloses a method for selecting a packet data network.

[0033] In this embodiment, a scenario in which a WiMAX access network accesses an EPC is taken as an example to describe a method for an MS / UE to select an Additional PDN in CMIPv4 mode. The method is as figure 1 As shown, the specific steps are as follows:

[0034] Step 101, the MS / UE accesses the EPC network through the WiMAX ASN network, establishes a link with the default PDN, and establishes a MIP tunnel between the FA and the PDN GW (PDN GW1 in the figure). The process described is the prior art and will not be repeated here.

[0035] Step 102, FA (foreign agent, foreign agent) sends MIP Adv (MIPAdvertisement, MIP broadcast) message to MS / UE, and t...

Abstract

The embodiment of the invention discloses a method and a device for selecting a packet data network (PDN) to realize selection of new PDNs by a terminal. The method comprises the following steps: receiving the PDN selection information from the terminal; sending the PDN authorization request information to an authentication device; the PDN authorization request information carries the PDN selection information so that the authentication device selects a PDN gateway (GW) for the terminal according to the PDN subscription information and the PDN selection information from the terminal; the above information is stored in the authentication device. The device comprises a receiving module, a storing module and a PDN selection function module.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method and device for selecting a packet data network. Background technique [0002] 3GPP (3rd Generation Partnership Project, third generation partnership project) and 3GPP2 (3rd Generation Partnership Project 2, third generation mobile communication standardization partner project 2), WiMAX (Worldwide Interoperability for Microwave Access, global access microwave interoperability) etc. are the mainstream standards of the existing third-generation communication technology. Intercommunication and service sharing between several standard networks has always been an indispensable branch of technological development. [0003] In the process of accessing from a non-3GPP (non-3rd Generation Partnership Project, non-third generation partnership project) access system to an EPC (Evolved Packet Core, evolved packet system core network), the terminal, usually called M...
