Problems solved by technology

[0012] Due to the theoretically huge number of users connected by AGCF, it takes a long time for MG to re-register. During this registration time, if the MG is called again, it must reject the call because it has not registered on AGCF2. resulting in call loss

Embodiment Construction

[0032] 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.

[0033] 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).

[0034]This embodiment provides a call processing method, Figure 4 It is a flow chart of the call processing method implemented according to the present invention, such as Figure 4 As shown, the process includes the following steps:

[0035] Step S402, after the MG switches from the first MGC it registered to the second MGC, the user on the MG is called (also called MG called);

[0036] Step S404, the upper-layer network element sends the user informat...

Abstract

The invention discloses a calling processing method and a system thereof. The method comprises the following steps: after a media gateway MG is switched to a second media gateway controller (MGC) from a first media gateway (MGC) where the MG is registered, the MG is called; an upper level network element sends user information of the MG to the second MGC; the second MGC initiates a register flow of the MG to the upper level network element, and calling is in continuation. Through the method and the system, 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...
