Background technology
Develop rapidly along with packet network, Media Gateway Controller (Media Gateway Controller, MGC) and media gateway (Media Gateway, MG) two key members in the packet network have been become, wherein MGC is responsible for CCF, MG is responsible for the service bearer function, thereby realizes calling out separating of control plane and service bearer plane.The main agreement of communicating by letter between MGC and the MG is a gateway control protocol, as agreement etc. H.248.In agreement H.248, the various resources on the MG are taken out to being expressed as terminal, and terminal is divided into physical terminal and ephemeral terminations again, and on behalf of some, physical terminal have semi-permanent physical entity, as time division multiplexing (Time Division Multiplex, TDM) etc.; The public resource that on behalf of some provisional application, ephemeral terminations use the back to discharge, for example RTP (Real-time TransportProtocol, RTP) stream etc.
Under MGC and framework that MG separates, MGC and MG exchange the specific resources that will control or operate by terminal iidentification, the minutia of this resource is by MG internal distribution and control, for example: represent plain old telephone service (Plain Old Telephone Service for one, POTS) resource of the physical terminal representative of port can be the 3rd port of the 2nd groove position of the 1st machine frame on this MG hardware device, the 4th time slot of the 3rd relaying of the 2nd trunk group of the 1st office direction that resource of representing the physical terminal representative of TDM passage can be this MG, one is represented the resource of the ephemeral terminations representative of rtp streaming can be the 2nd Digital Signal Processing (Digital SignalProcessing on the 1st interface board, DSP) the 3rd of chip the passage, or the like.Though therefore MGC may know the character of certain terminal, for example is the physical terminal ephemeral terminations, represent the POTS port or represent the TDM passage, but do not understand this terminal details of the specific resources of representative behind.
When MGC need know that MG goes up the resource information of certain terminal representative, operation will be very loaded down with trivial details like this.For example MGC or other operation maintenance system need be understood a terminal fault and represented MG to go up which hardware resource fault so that when safeguarding, just need to obtain from MGC according to fault warning information earlier the terminal iidentification of fault, obtain the resource information of this terminal representative again from MG with this terminal iidentification, such operating process is more loaded down with trivial details, is unfavorable for the raising of system effectiveness.Existing a solution is to add resource information in terminal iidentification, for example identifies the physical terminal of representing the POTS port with " POTS-frame/groove/port " form, makes MGC in this way just can directly know the concrete resource information of a terminal.
In realizing process of the present invention, the inventor finds prior art, and there are the following problems at least: MGC does not need to know the resource information of terminal under many circumstances, add that on each terminal iidentification concrete resource information will strengthen the shared system resource of transmission terminal sign, reduces the efficient of system; And will be originally can take the terminal iidentification of any nomenclature scheme and resource information to bundle, the formation and the length of terminal iidentification constituted influence by MG.But especially when the resource dynamic change of terminal representative, for example certain shared dsp chip passage of ephemeral terminations of representing rtp streaming is when 1 becomes 2, just need change terminal iidentification, this more can bring the complexity of system handles, thereby reduces the efficient of system.
