Description
Technical field
The present invention relates to wireless digital intercom private communication technical field, relate in particular to a kind of voice transmission method and system.
Background technology
In the existing dmr voice superframes, except that voice head frame, all carrying identical colour coding and personal information parameter (structure as shown in Figure 1) in each voice bursts.
As shown in Figure 2; Said embedding signaling is arranged on the centre of each voice bursts; In each voice bursts, being provided with when embedding signaling, specifically is to be placed on the two ends that embed signaling parameter with embedding territory content (embedding the territory content specifically comprises: colour coding, personal information, initial termination indication);
According to voice superframes structure shown in Figure 1, receiving terminal is analyzed the information of carrying in the whole voice head frame after obtaining voice head time slot:
At first obtain synchronously.The parameter at synchronous code two ends is resolved in the back synchronously, and whether this this time slot of parameter indication is voice head time slot.
Receive voice head time slot, and extract link Control Parameter in the time slot, confirm whether be voice LC (controlling links) frame;
If confirm it is a voice LC frame, then preceding 98bit in this time slot and back 98bit are carried out unified Analysis (LC controlling links), obtain type of call (confirming that through this type of call this time calling is individual calling or group calling), destination address, obtain source address;
Receive the A time slot, subsynchronous again;
Receive BCDEF time slot data, resolve the same color and the personal information of carrying in each time slot, embed signaling parameter and resolve source address and information such as destination address.
Because identical colour coding and personal information added in each voice bursts in the technology now,, reduce system transmissions efficient so can increase overhead.
The parameter that embeds in the content of territory is positioned over the embedding signaling parameter two ends behind the channel code interleaving after splitting, this kind mode has increased the complexity and the overhead of distinguish of system signaling.
Because voice head time slot contains identical synchronous code with synchronization slot, has increased system's unnecessary spending, has reduced system transmissions efficient.
Because the controlling links signaling of being carried in voice head time slot and the BCDEF time slot is identical; Because the unsteadiness of transmission system and the finiteness of error correcting capability; Under the situation of system's generation error code and correctly error correction; Make this voice bursts of the high level property be not sure of identification professional, can't certainty accomplish the foundation of whole voice call link.For example:
During individual calling: after receiving voice head time slot, receiving terminal can be resolved the controlling links signaling.Can resolve colour coding, source address, destination address in the voice head time slot, receiving terminal can be set up respective receiver system according to these three parameters.Colour coding among the BCDEF, source address, destination address are identical with A; If error code occurs in optional position in colour coding, source address or the destination address; And exceeded the error correction scope; Should identical information dissimilate among a time slot and the BCEDF this moment, thereby make receiver certainty set up voice call link.
