Description
Technical field
The present invention is that application number is 2011101319078, and the applying date is on 05 19th, 2011, and name is called " a kind of voiceTransmission method and system " the divisional application of patent of invention, it relates to wireless digital intercom private communication technical field, especiallyRelate to a kind of voice transmission method.
Background technology
In existing dmr voice superframes, except voice head frame, in each voice bursts, all carrying identical colour coding with privateInformation parameter (structure as shown in Figure 1).
As shown in Figure 2, described embedding signaling is arranged on the centre of each voice bursts, in each voice bursts, embedding is setWhile entering signaling, specifically will embed territory content (embedding territory content specifically comprises: colour coding, personal information, initial termination instruction) and putPut at the two ends that embed signaling parameter;
According to the voice superframes structure shown in Fig. 1, receiving terminal is obtaining after voice head time slot, analyzes the whole voice head of carryingInformation in frame:
First obtain synchronous. The parameter of resolving synchronous code two ends after synchronous, this parameter indicates whether this time slot is voice headTime slot.
Receive voice head time slot, and extract a time slot link control parameter, be confirmed whether into voice LC (link control)Frame;
If be confirmed to be a voice LC frame, the front 98bit in this time slot and rear 98bit are unified point
Analyse (control of LC link), obtain type of call (determining that by this type of call this calling is individual calling or group calling),Destination address, obtain source address;
Receive A time slot, more subsynchronous;
Receive BCDEF time slot data, resolve same color and the personal information of in each time slot, carrying, embed signaling parameter alsoResolve the information such as source address and destination address.
Because in technology, identical colour coding and personal information added in each voice bursts now, so can increase systemSystem expense, reduces system efficiency of transmission.
The parameter embedding in the content of territory is positioned over the embedding signaling parameter two ends after channel code interleaving after splitting, shouldThe mode of kind has increased complexity and the overhead of distinguish of system signaling.
Because voice head time slot contains identical synchronous code with synchronization slot, increase the unnecessary expense of system, reduceSystem efficiency of transmission.
Because voice head time slot is identical with the link control signal carrying in BCDEF time slot, due to transmission system notThe finiteness of stability and error correcting capability, when in the situation of system generation error code and correctly error correction, can not determine high levelProperty is identified this voice bursts business, cannot certainty completes the foundation of whole voice call link. For example:
When individual calling: receive after voice head time slot, receiving terminal can be resolved link control signal. In voice head time slot, can resolveColour coding, source address, destination address, receiving terminal can be set up corresponding reception mechanism according to these three parameters. Colour coding in BCDEF,Source address, destination address are identical with A, if error code occur in colour coding,
Optional position in source address or destination address, and exceeded error correction scope, now should phase in a time slot and BCEDFSame information dissimilates, thereby makes receiver certainty set up voice call link.
