Embodiment Construction

[0036] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. 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 with each other.

[0037]In this embodiment, the MGC is taken as an example for illustration, but the MGC here includes network entities and functional modules capable of implementing MGC functions, for example, an Access Gateway Control Function (AGCF for short).

[0038] In this embodiment, a call processing method is provided, Figure 4 is a flowchart of a call processing method according to an embodiment of the present invention, such as Figure 4 As shown, the process includes the following steps:

[0039] Step S402, the MG switches from its registered first MGC to the second MGC;

[0040] Step S404, the MG initiates a call;

[0041] In step S406, the second MGC initiates a registration process of the MG to th...

Abstract

The invention discloses a call processing method and a call processing system. The method comprises the steps of: switching a first media gateway controller (MGC) registered by a media gateway (MG) to a second MGC by the media gateway (MG); initiating a call by the MG; initiating a registration flow of MG to a network element at the upper layer and continuing to connect the call by the second MGC. In the invention, call loss is reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a call processing method and system. Background technique [0002] In the next generation network (Next Generation Network, referred to as NGN) and IP Multimedia Subsystem (IP Multimedia Subsystem, referred to as IMS), by separating the traditional switch into a media gateway controller (Media Gateway Controller, referred to as MGC) and a media gateway ( Media Gateway, referred to as MG), utilizes the characteristics of IP / ATM transmission network, on the one hand, it can realize the interaction of voice, image, and data, and on the other hand, MGC can introduce more services more easily. The MGC can also communicate with traditional Public Switched Telephone Network (PSTN for short) and Public Land Mobile Network (PLMN for short) networks through MG. [0003] In the next generation network, H.248 or Media Gateway Controller Protocol (MGCP for short) (the application scenarios...
