Problems solved by technology

Since the MGC does not inform the MG under which network domain the local transport address should be allocated, the terminal of the media gateway in the prior art can only allocate the local transport address in the default or pre-designated network domain of the MGC, and cannot allocate the local transport address in other non-default or non-default network domains. The local transmission address is allocated in the network domain pre-designated by the MGC, so that the terminal cannot communicate with other non-default or non-MGC pre-designated network domains, which reduces the utilization efficiency of the terminal

Embodiment Construction

[0028] In order to make the object, technical solution, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0029] figure 1 The flow of the embodiment of the local transmission address allocation method provided by the present invention is described, including:

[0030] Step 101: Receive an H.248 protocol message; the H.248 protocol message includes local transport address information to be allocated and a domain identifier of a network domain corresponding to the local transport address to be allocated.

[0031]Among them, the H.248 protocol is a media gateway control protocol. The media gateway can assign multiple local transport addresses to the terminal, and the above-mentioned multiple local transport addresses may be located in different network domains, so the H.248 protocol message carries the local transport address information to be allocated and ...

Abstract

The invention relates to the technical field of networks, and discloses a distribution method of a local transport address, a media gateway and a media gateway controller. The distribution method of the local transport address comprises the following steps: receiving a H.248 protocol message, wherein the protocol message comprises a local transport address message required to be distributed and a domain identifier of a network domain corresponding to a local transport address required to be distributed; and distributing the local transport address in the network domain corresponding to the domain identifier, wherein the local transport address distributed is corresponding to the local transport address message. By using the technical scheme provided by the embodiment of the invention, the media gateway can simultaneously distribute the local transport address in a plurality of network domains for a terminal, so that the terminal can be simultaneously communicated with a plurality of networks, thereby improving the utilization efficiency of the terminal.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a local transmission address allocation method, a media gateway and a media gateway controller. Background technique [0002] Next Generation Network (NGN: Next Generation Network) is based on Time Division Multiplexing (TDM: Time Division Multiplex and Multiplexer) Public Switched Telephone Network (PSTN: Public Switched Telephone Network) and Internet Protocol / Asynchronous Transfer Mode (IP / ATM: Internet Protocol / Asynchronous Transfer Mode) packet network fusion product, it makes it possible to realize integrated services such as voice, video and data information on the same network, marking the arrival of a new generation of telecommunication network era. [0003] The existing NGN network mainly includes a media gateway (MGW: Media Gateway) and a media gateway controller (MGC: Media Gateway Controller). Among them, MGC is used to realize the management of call state and the ...
