The multimedia message arrival notice that S32, reception MMS center send;
S33, resolve the multimedia message arrival notice, obtain the address of multimedia message in the MMS center server according to MMS (Microsoft Media Server) Protocol;
Forward step S35 to if S34 resolves successfully, otherwise forward S48 to;
S35, initialization network settings, configuration access access point (APN);
S36, requesting activation packet data network (PDP, Packet Data Protocol) scene;
S37, judge whether the PDP scene is activated, and is then to forward step S38 to, otherwise forward step S48 to
S38, acquisition Virtual network operator IP address allocated;
S39, initiate TCP as client to WAP gateway and connect, successful then preserve the TCP send window, the size of receive window also forwards step S40 to, and failing then forwards S48 to;
S40, reception MMS packet data;
S41, judgement receive in the buffering area whether also have the MMS packet data, if having, then forward step S42 to, otherwise forward step S40 to;
S42, the data that parsing is received according to MMS (Microsoft Media Server) Protocol;
S43, judge whether to resolve successfully,, otherwise forward step S48 to if success then forwards step S44 to
S44, sender information is outputed to serial ports;
S45, close TCP and connect;
S46, disconnection GPRS connect;
S47, prompting receive successfully prompting, finish whole flow process;
S48, the prompting prompting that takes defeat finish whole flow process.
The present invention is in order to solve the multimedia message service function of GSM/GPRS module, for the user provides complete embedded GSM/GPRS multimedia message service module scheme, the implementation method of the embedded MMS (Microsoft Media Server) Protocol of a kind of GSM/GPRS wireless module (multimedia message protocol) is provided, and corresponding radio data transmission method and radio communication device for this reason: MMS (Microsoft Media Server) Protocol is embedded in the wireless module, communication terminal is by expansion AT command operate wireless module, setting up by the GPRS GPRS network on the basis of wireless connections, receiving and send multimedia message.The user can pass through simple serial communication, realizes the editor and the transmission-receiving function of multimedia message, like this in the taking all factors into consideration of reliability/price/communication efficiency/construction cycle, and can both be even better.
