Description
Technical field
The present invention relates to wireless mobile telecommunication technology field, what be specifically related to is a kind of realize the wireless voice of multiple priority levels business and the method for data corresponding.
Background technology
DMR(DigitalMobileRadio) be European Union ETSI standardization body propose professional mobile radio system standard, this standard contains TierI, TierII and TierIII tri-kinds of operating mode, wherein: TierI refers to network-off direct-passing communication pattern; TierII refers to transfer communication pattern; TierIII then refers to trunking communication pattern.
In actual applications, network-off direct-passing and transfer communication are the most frequently used communication patterns, the TDMA technical system of gap when DMR air interface adopts 2, although when terminal works in certain for the moment gap time, it is possible to realized the priority of different business by the backward channel (RC) of gap during another one; But, for 2 channel TDMA technical systems, backward channel then cannot be utilized to select to realize the priority of business when 2 channels are in " doing " state simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is for the implementation method of the voice service of each channel and the multiple priority levels of data service in DMR technological standard, thus propose a kind of to realize the wireless voice of multiple priority levels business and the method for data corresponding, the method takes full advantage of the superframe structure in DMR to realize the multiple priority levels feature of speech and data service, it is thus possible to meet specialty client better to the demand of service priority so that DMR technological standard can be applicable to more application scenario.
The present invention is achieved by the following technical solutions: a kind of realizes the wireless voice of multiple priority levels business and the method for data corresponding, utilize the superframe structure of DMR air interface, just reserve the use of for some time to terminal access every the time of 1 or 2 superframe; Each superframe any " stealing " one frame burst is as the time of other-end access, and will now gap be defined as " during channel access gap ".
A described superframe is 360ms, when there is channel access in it the aerial burst structure of DMR during gap comprise be containing vertical hold burst A, the B that happens suddenly containing gap when embedded signaling and channel access, the C that happens suddenly containing embedded signaling, the D that happens suddenly containing embedded signaling, the E that happens suddenly containing embedded signaling, happen suddenly F containing backward channel signaling; Described removing at burst B location specifies to send beared information, namely outside the normal embedded signaling sent, all the other time closes and launches, so that channel is in idle state, like this, other-end just can initiate channel access request when the service priority finding that priority ratio this locality of ongoing business to be ready initiating is low.
During channel access during described data service, the bit definitions of gap is channel access request time (72bits)-Transmit enable time (26bits)-time slot type (10bits)-embedded signaling (48bits)-time slot type (10bits)-Transmit enable time (26bits)-channel access answering time (72bits).
During channel access during described voice service, the bit definitions of gap is channel access request time (72bits)-Transmit enable time (36bits)-embedded signaling (48bits)-Transmit enable time (36bits)-channel access answering time (72bits).
The implementation method of service priority is, because, in DMR air protocol, the service priority that embedded signaling comprises has 3 grades, and wherein priority 3 has the highest priority; When service priority ongoing in channel is 1, the terminal of priority 2 initiates the time that the timed interval of channel access request is 2 superframes, that is, even if the burst point of each superframe all available free time is used for channel access, but still sends 1 access request every 2 superframe times; It is 1 superframe time that the terminal of priority 3 initiates the timed interval of channel access request, as long as that is, not yet accessing channel, so just sends 1 channel access request every the time of 1 superframe; When service priority ongoing in channel is 2, it is 1 superframe time that the terminal initiation channel of priority 3 connects the timed interval of access request; So on the one hand, when user easy more time prevent too much user from initiating channel access request in the same moment and cause channel block, on the other hand, the method also embodies the preferential concept of business on the channel access timed interval.
The useful effect of the present invention embodies and is: gap when 1, defining channel access based on existing DMR standard agreement; 2, by utilizing channel access time, gap achieves the priority channel right to use of speech and data service.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention will be described in detail.

Embodiment
As shown in Figure 2 to Figure 3, by the definition of gap during channel access it will be seen that first other-end initiates channel access request in gap at this moment, the terminal then communicated can sending channel access response information, to be confirmed whether to accept this channel access request; When voice service is transmitted by superframe structure, if the speech information (speech information of 60ms) of gap when the superframe time of 360ms removes, simultaneously on receiving end uses, the speech information of a 60ms is used as this time gap speech information and delivers to loudspeaker and play, and now voice quality impacts is very little; Therefore, the channel access function realizing other-end by the method for " steal frame " is completely feasible.
As shown in Figure 4, when channel carrying out business and is transmitting, for the business flow process the other-end not participating in this communication.
As shown in Figure 5, for the terminal being in communications status, when receiving the channel access request that other-end is initiated in the gap when channel access, judge the priority information comprised in channel access request, if being greater than local ongoing service priority, the channel access response information then sending confirmation is to requesting party, and gap stops this communication process immediately when the next one.
As shown in Fig. 2, Fig. 3 and Fig. 6, channel access request and channel access response information are 72bits, wherein: that channel access request comprises is the ID(24bits of requesting party) and service priority information (2bits); That channel access response comprises is the ID(24bits of response side) and response content (2bits).
Terminal in the inventive method is when realizing service priority function, need the Transmit enable speed of hardware enough fast, just in the terminal of communication in process of transmitting, need the gap when channel access to realize receiving function, simultaneously when identical, send embedded signaling information and channel access response information in gap. Therefore, it is desired to hardware can support that transmitting-receiving speed is enough fast, should realize Transmit enable within the timed interval of 2.5ms.
