Embodiment Construction

[0034] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0035] In the embodiment of the present invention, after the target AN starts the A13 handover request process, the source AN transfers the core network data cached by the source AN to the target AN through an A13-SessionInformation Response (A13 handover session information response) message.

[0036] Such as figure 2 As shown, the A13 DataInformation (A13 data information) field is added to the A13-Session Information Response message;

[0037] Such as image 3 As shown, the A13 interface adds the identification value 1AH of the A13 Data Information field; the identifica...

Abstract

Disclosed are a method for transmitting core network (CN) data across access networks (ANs), and an AN. The method comprises: after a source AN of an access terminal (AT) receives an A13 session information request message sent by a target AN of the AT, sending an A13 session information response message to the target AN, the A13 session response message carries the CN data of the AT cached by the source AN. By using the above technical solutions, CN data of non-A24 interfaces can be transmitted across the ANs, simplifying data transmission operations across ANs.

Description

technical field [0001] The invention relates to a mobile communication system, in particular to a method for transmitting core network data between access networks and an access network. Background technique [0002] Such as figure 1 As shown, in the EVDO system that supports the Secondary Colorcode (secondary color code) function, there are multiple AN (Access Network, access network) border base stations (BTS) that are configured with each other's Colorcode ( Color code) is the Secondary Colorcode of the base station. Such as figure 1 As shown in , base station A configures the Colorcode (value 8) of base station B as the secondary colorcode of the base station, and base station B configures the Colorcode (value 7) of base station A as the secondary colorcode of the base station. When the state of the AT (Access Terminal, terminal) in the source AN changes from the active state to the idle state, it moves to the target AN, including: [0003] Step 101: AT moves across ...
