Problems solved by technology

[0009] The current inter-office handover mechanism requires the joint participation of E-interface MAP (Mobile Application Part, mobile application part) signaling and inter-office relay signaling. In DSN (Distributed Service Network), the introduction of dynamic nodes makes mAGCF Signaling interaction no longer depends on No. 7 signaling, and the traditional switching MAP signaling process cannot be realized

Embodiment Construction

[0063] 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.

[0064] figure 2 It is a flow chart of the mAGCF inter-office handover in Embodiment 1 of the present invention, including the following steps:

[0065] Step 201, handover source side RNC-A sends Iu mouth handover request message (Iu-Relocation-Require) to handover source side mAGCF-A;

[0066] Step 202, the handover source side mAGCF-A encapsulates the E interface MAP message (MAP-Prep-Handover Req, ready to handover request message) in the SIP INVITE message, and sends it to the target side mAGCF-B;

[0067] Both the Require (request) and Supported (support) header fields...

Abstract

The present invention provides a switching method and mAGCF in a DSN. The method includes: after receiving a switching request message from the wireless side, the first mAGCF sends a SIP INVITE message to the second mAGCF, and the SIP INVITE message carries an E-port MAP switching request message; after the first mAGCF receives the SIP-encapsulated MAP handover response message of the second mAGCF, establishes an interoffice handover bearer with the second mAGCF; after the first mAGCF receives the SIP-encapsulated MAP ready to handover message of the second mAGCF, The first radio network controller is notified to switch the user to the second radio network controller controlled by the second mAGCF. The present invention can realize the switching process between mAGCF offices in the DSN domain.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method for switching between mAGCF (mobile Access Gateway Control Function, mobile access gateway control function entity) offices in a distributed service network (Distributed Service Network, DSN for short) and the mAGCF. Background technique [0002] Internet Protocol (IP for short) Multimedia Subsystem (IP Multimedia CoreNetwork Subsystem, IMS for short) is an IP-based network architecture proposed by the 3rd Generation Partnership Project (3GPP for short). It provides an open and flexible business environment, supports multimedia applications, and provides users with rich multimedia services. [0003] IMS has nothing to do with the access technology. In addition to providing services for GPRS (General Packet Radio Service, General Packet Radio Service), WLAN (Wireless Local Area Network, Wireless Local Area Network) and other packet (Packet Switching, PS) access...
