Problems solved by technology

[0008] The inventor found in the actual application process that at least the following problems exist in the prior art: the above-mentioned prior art needs to control the media in real time through range information, which requires that the user and the media provider need to understand the range information representation supported by the other party capabilities, thus creating a need for the exchange of their respective range-related information representation capabilities
At the same time, under the framework where the MGC and MG are separated, sometimes real-time control of the media is also involved, because the user controls the media transmission on the MG through the MGC, so if the real-time control of the media is to be carried out through range information, this needs to be done in the Between the MGC and the MG, it is necessary to provide a corresponding support mechanism for exchanging range information representation capabilities supported by the user and the MG respectively. However, the above-mentioned prior art does not provide a solution for exchanging the range information capabilities between the MGC and the MG.

Embodiment 1

[0054] Embodiment 1. A range information representation capability interaction method, the method flow is as follows figure 1 As shown, it specifically includes the following steps:

[0055] Step 101, MGC sends a request command to MG, and the request command carries extended attributes, such as rfi / ft attributes, and MGC sends a request to MG to support range information indicating capabilities through this attribute. Wherein, when the request command is a command type such as Add, Modify, Move or Subtract, the rfi / ft attribute carried by the request command represents the scope information representation capability that the MGC requests the MG to support.

[0056] Optionally, the MGC sends a request for the range information representation capability supported by the MG through the rfi / ft attribute, and requests the MG to report the supported range information representation capability through the rfi / ft attribute.

[0057] Step 102: The MG determines the supported range in...

Embodiment 2

[0072] Embodiment 2, a kind of media gateway, refer to figure 2 , the media gateway includes:

[0073] The first message transceiving unit 201 is configured to receive a request command sent by the media gateway controller, and send a response command to the media gateway controller;

[0074] The first capability exchanging unit 202 is configured to obtain, from the request command, the range information representation capability requested to be supported, and / or obtain an indication of the range information representation capability requested to be reported to be supported, and determine the supported range information representation capability, and The supported range information representation capability is set in the response command.

[0075] Optionally, the media gateway includes:

[0076] The second message transceiving unit is configured to receive a request command sent by the media gateway controller, and send a response command to the media gateway controller;

...

Embodiment 3

[0078] Embodiment 3, a media gateway controller, refer to image 3 , the media gateway controller includes:

[0079] The third message transceiving unit 301 is configured to send a request command to the media gateway, and receive a response command sent by the media gateway;

[0080] The third capability exchange unit 302 is configured to set the range information representation capability requested to be supported in the request command, and / or request the media gateway to report the indication of the supported range information representation capability, and obtain the supported range information representation capability from the response command Range information representation capabilities.

[0081] Optionally, the media gateway controller includes:

[0082] The fourth message transceiving unit is configured to send a request command to the media gateway, and receive a response command sent by the media gateway;

[0083] The fourth capability exchanging unit is config...

Abstract

The invention relates to the field of radio communication, and discloses a method for interacting with extent information representation capacity, as well as a media gateway and a media gateway controller. The method comprises the following steps: the media gateway receives a request command transmitted by the media gateway controller; the request command is used for issuing the extent information representation capacity supported by a request; and the media gateway determines the extent information representation capacity supported according to the extent information representation capacity supported by the request. The invention can interact with the extent information representation capacity between the media gateway and the media gateway controller.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a range information representation capability interaction method, a media gateway, and a media gateway controller. Background technique [0002] Media Gateway Controller (MGC, Media Gateway Controller) and Media Gateway (MG, Media Gateway) are two important devices under the structure of separation of service control and bearer. MGC is responsible for service control function, and MG is responsible for media bearer function, so that service The separation of the control plane and the media bearer plane enables the full sharing of network resources, simplifies equipment upgrades and service expansion, and reduces development and maintenance costs. [0003] There are two widely used communication protocols between MG and MGC: Gateway Control Protocol (GCP, Gateway Control Protocol) and Media Gateway Control Protocol (MGCP, Media Gateway Control Protocol). The GCP protocol is d...
