Background technology
MGCP (Media Gateway Control Protocol is called for short MGCP) is the internet engineering service groups RFC2705 agreement of (The Internet Engineering Task Force is called for short IETF).It comprises two basic agreements, i.e. SGCP (Simple GatewayControl Protocol is called for short SGCP) and IP device control protocol (Internet Protocol DeviceControl is called for short IPDC).
Be illustrated in figure 1 as the soft switchcall server networking diagram of realizing the MGCP agreement in the prior art.Wherein the MGCP agreement has adopted separation gateway thought, and (Core net) is decomposed into two parts with core network: media gateway (Media Gateway is called for short MG) 101 and call proxy server (Call agent is called for short CA) 102.CA and MG are the network elements in the network, finish communication by the MGCP agreement between they are mutual: CA is used for processing signaling, MG is used to handle medium, and the action of CA may command MG, promptly send the order that to carry out to MG by CA, MG is equivalent to main (master) with the information reporting of being collected to CACA, and MG is equivalent to subordinate (slave).Agreement as application layer, the MGCP protocol definition signaling transmission means between CA and the MG, be a kind of based on the transmission mechanism of affairs transmission (Transaction) at MGCP agreement bearer network, the bearer network of this transmission action can be internet or ATM networks (ATM).
MGCP protocol interface message is made up of command messages and response message.Wherein, comprise command header in the command messages, comprise head response in the response message, all comprise Transaction Identifier Transaction ID in command header and the head response, but in the prior art its method of distinguishing is existed following defective:
The MGCP signaling processing entity is preserved it to the response of nearest affairs loopback and the affairs of carrying out at present in memory.After receiving orders, compare,, then do not carry out, retransmit this response if this order was handled with nearest response; Otherwise compare with the current affairs of carrying out: find coupling (RFC2705 judges that according to transaction flag RFC3435 combines domain name and affairs ID come), then return a Temporary Response (Pending) message, expression is carried out; If new affairs are then handled accordingly to this order.
In implementation procedure, if simply rely on the desired Transaction ID of RFC2705 agreement can not distinguish different affairs fully from different media gateway (MG), if distinguish different affairs according to the same media gateway of Transaction ID (MG) domain name in the RFC3435 agreement, influence efficient again greatly.
Proposition of the present invention also overcomes the low efficiency problem of RFC3435 agreement when distinguishing different affairs simultaneously just in order to overcome the defective that can not clearly distinguish different affairs in the RFC2705 agreement.
