[0021] A method for realizing H.248 message compatibility according to the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0022] Figure 1 is a flow chart of MGW registration specified in the H.248 protocol, including the following steps:
[0023] Step 101: The signaling link between the MGW and the MGC is restored;
[0024] Step 102: The MGW actively sends a registration request message to the MGC;
[0025] Step 103: The MGC sends a registration response message to the MGW, and the MGW enters a working state after receiving a positive registration response message.
[0026] Step 104: MGW and MGC use H.248 to carry out normal call flow. At this time, if MGW receives an unrecognized function package, MGW will return an error response to MGC, and the call cannot be carried out.
[0027] Fig. 2 is that the present invention proposes H.248 message compatibility flowchart, comprises the following steps:
[0028] Step 2...
