The recognition results are of two types: if the identification is successful, the returned result is matched, and if the identification is failed, the returned result is not matched; the other is as follows: and displaying the recognition result in a different return code identification mode.
Step 205: the MCIS102 returns a response message to the MMSC101, where the response message includes a content identification result corresponding to the multimedia information.
Here, the MCIS102 returns a response message to the MMSC101, specifically: the MCP-content-process.res response message is replied. The response message should have a response status code field, and the content of the response status code field is different according to the matching result. For example: if MCIS102 successfully completes the identification of the multimedia message, then the response status code field is "OK"; if the recognition fails, the response status code field indicates the reason of the recognition failure, etc.
Step 206: and the MMSC101 performs corresponding operation processing according to the identification result of the multimedia message content returned by the MCIS 102.
For example: after receiving the response message of the MCIS102, the MMSC101 determines the identification result, and if the identification result is "prohibit forwarding", the MMSC101 stops the forwarding process of the multimedia information. For another example, if the MMSC receives the response message of the MCIS102, then the MMSC101 determines the identification result, and if "allow forwarding", then the MMSC may forward the multimedia message to other MMSCs or other mobile terminals.
