Embodiment Construction
[0036] The basic idea of the present invention is: in the voice concurrent data service call establishment stage, the data service frame is preferentially multiplexed on the logical channel, and after the concurrency is successful, the voice frame is preferentially multiplexed on the logical channel to improve the call success rate of the voice concurrent data service .
[0037] The method of the present invention will be described in detail below by taking the logical channel FCH frame format PDU Type1 of the MAC layer as an example. On the FCH, the main service data block multiplexes the voice frame, the secondary service data block multiplexes the data service frame, and the signaling service data block multiplexes the air interface signaling.
[0038] The method for realizing voice concurrent data call provided by the present invention, such as Figure 4 As shown, the method includes the following steps:
[0039] Step 401: the multiplexing sublayer of the SDM judges wh...
