Problems solved by technology

[0014] (3) There is a possibility of bearer intercommunication between Contexts in a VMGW
The biggest disadvantage of using real bearer for intercommunication is the occupation of actual physical bearer resources, resulting in a significant reduction in the port density of MGW equipment, which may be reduced by about half in extreme cases—for example, MGC occupies two contexts on one MGW for each common call When the way is realized
This is an unacceptable loss of specification for the device
On the other hand, the networking is complex, such as the external loopback TDM trunk mode still needs to configure the corresponding trunk cable, resulting in too many redundant wiring

Embodiment Construction

[0052] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0053] Under the separation architecture, a flexible MGW that can support integrated services and has long-term evolution capabilities can have the following logical structure:

[0054] OAM Units: Provide the operation and maintenance functions of the entire system, such as security management, configuration management, log management, alarm management, performance management, tracking management, etc., and provide interfaces to external operation support systems.

[0055] Narrow Band Units: Provides the interface and protocol processing functions of the device to the narrowband side. Based on the TDM technology, it provides a low-level abstraction of the TDM bearer. Usually, the physical resources (such as the switching network) required by TDM switching are provided here.

[0056] Broad Band Units: provide interfaces and protocol processing functions to the broadb...

Abstract

The invention provides a method for realizing the carrier intercommunication based on the virtual relay, including the following steps: a: the logic function part and logic function controller configure the virtual relay data; b: the logic function part analyzes the topology; c: the logic function part combines the virtual relay end V_T1 involved in the change information of the topology connection from the topology analysis with another virtual relay end V_T2 or true end T1. The invention also provides system for realizing the carrier intercommunication based on the virtual relay. The invention can solve the intercommunication inside the gateway and does not reduce the density of the physical port of the gateway, so it shows its strength in the pure TDM networking application. In addition, its realization is flexible and simple and does not depend on the specific telecom service.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and system for realizing bearer interworking based on a virtual relay. Background technique [0002] Under the separated architecture, the main bodies of the call control plane and the bearer control plane are MGC (Media Gateway Controller) and MGW (Media Gateway) respectively. The MGW accepts the control of the MGC, and the interface protocol is called the media gateway control protocol, which is defined as the H.248 series specification in Itu-t. [0003] The MGW provides specific bearer resources for calls / sessions. In the H.248 protocol model, Context (context) and Termination (endpoint) are the two most important concepts. Among them, Termination is an abstraction of bearer resources on the MGW, and the gateway assigns an Id to identify it. The MGC uses this Id to refer to and operate on the bearer resources on the MGW. A Termination can be used to identify a TD...
