Abstract:
1. A method for implementing a radiophone based conference call, when a conference call is required for one or more radiophones, the method comprising the steps at a radiophone serving as a transmitting end of a group: a. selecting a group ID of an intended group and a group ID of an intended temporary conference call through a man-machine interface of the radiophone serving as the transmitting end; b. writing an ID of the transmitting end, the group ID of the intended group and the group ID of the temporary conference call into a preset protocol stack module, and generating a control packet used to set up the temporary conference call in a coding format and via an extensible interface, the coding format and the extensible interface being inherent to the preset protocol stack module; and c. transmitting the control packet for setting up the temporary conference call to a corresponding radiophone serving as a receiving end in a control frame directly; and the method comprising the steps at one or more radiophones serving as receiving ends of the intended group: d. decoding the control frame transmitted from the radiophone serving as the transmitting end; e. determining whether the one or more radiophones serving as the receiving ends are subjects to an operation from the control frame, and if it is determined that the one or more radiophones serving as the receiving ends are subjects to an operation from the control frame, going to step f; otherwise, skipping the control frame and ending; and f. initiating a frequency modification module to modify frequency modification information by adding the group ID of the temporary conference call, so that the temporary conference call between the radiophone serving as the transmitting end and the one or more radiophone serving as the receiving ends is set up.
