Embodiment Construction

[0037] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] The present invention solves how to notify the HSS of the address information of the PDN GW.

[0039] Such as image 3 As shown, the embodiment of the present invention includes the following steps:

[0040] Step 301, the mobility management node learns that the address information of the PDN GW is not saved in the HSS, or the mobility management node reselects a PDN GW;

[0041] In step 302, the mobility management node notifies the HSS of the address information of the PDN GW for storage.

[0042] The mobility management node may be the MME when accessing the E-RAN, or the SGSN when accessing the GPRS.

[0043] In the step 302, the notification message passed by the mobility management node notifies the HSS of the address information of the PDN GW for storage, and the notification message needs to include a parameter: the address in...

Abstract

The invention discloses a method to inform an attribution user server HSS to protect grouping data net gateway PDN GW address information in the system structure developing. The method comprises the steps that a moving management node learns that the PDN GW address information is not stored in the HSS, or the moving management node afresh selects the PDN GW; the moving management node informs the HSS the address information to store the address information. Though the invention, the HSS can directly gain the PDN GW address information from an MME not through a 3GPP AAA server, and a roaming interface between the PDN GW and the HSS is avoided.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method for notifying HSS (Home Subscriber Server) to store PDN GW (Packet Data Network Gateway) address information in the evolution of system architecture. Background technique [0002] With the sudden emergence of Wimax (World Interoperability for Microwave Access, the third-generation mobile communication system must improve its network performance and reduce network construction and operation in order to maintain its strong competitiveness in the field of mobile communication. cost. Therefore, the standardization working group of 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) is currently working on researching PS Core (Packet Switch Core, packet switching core network) and UTRAN (Universal Mobile Telecommunication System Radio Access Network, The evolution of the Global System for Mobile Communications Radio Access Network), thi...
