The communication network includes a core network and UTRAN (Terrestrial Radio Access Network), and the mobile terminal and UTRAN performs wireless communication. Preferably, the mobile terminal is a terminal supporting 2G or 3G voice calls.
[0039] When the mobile terminal and the communication network realize the data interaction of the voice call, if the call needs to be hung up, the mobile terminal needs to send a disconnect signaling (hang up signaling) to the communication network or the communication network sends a disconnect signaling to the mobile terminal. The solution is that only the disconnect signaling needs to be applied when hanging up the call, that is, only the mobile terminal or the communication network needs to send the ...
