Embodiment Construction

[0064] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0065] The present invention carries the IP address capability information of the UE to the core network during the UE attachment process, and the core network judges the IP address capability information of the UE when assigning a PDP address to the UE, and allocates a PDP address of a corresponding IP address type.

[0066] In the first embodiment of the present invention, the realization process of the present invention in the 3GPP network is described.

[0067] Figure 5 The implementation process of user attachment in the 3GPP network in the present invention is shown:

[0068] 1. The UE ini...

Abstract

The present invention provides realizes PDP address assignment method in service accessing. Said method includes A, user equipment carrying supported address ability information to core network in attachment process; B, core network according to said IP address ability information and address information in user subscription data distributing relevant IP type PDP address to user equipment. The present invention can raise UE activating success ratio.

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to a method for allocating PDP addresses to user equipment and a method for realizing user attachment during the service access process of user equipment. Background technique [0002] The existing GPRS (General Package Radio Service, General Packet Radio Service) / UMTS (Universal Mobile Telecommunications System, Universal Mobile Telecommunications System) network structure is as follows: figure 1 As shown, a structure similar to that of the second generation mobile communication system is adopted, including UMTS (Universal Mobile Telecommunications System, universal mobile communication system) terrestrial radio access network (UMTSTerritorial Radio Access Network, UTRAN), GSM / EDGE radio access network ( GSM / EDGE Radio Access Network, GERAN), core network (Core Network, CN) and user terminal (User Equipment, UE). Among them, GERAN / UTRAN is used to implement all wire...
