Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The present application is based on the improvement of DMR (Digital Mobile Radio) and PDT (Police Digital Trunking) standards, and for convenience of description, the DMR standard is specifically used for description in the present application.
The DMR standard employs a Time Division Multiple Access (TDMA) frame structure of two Time slots. Fig. 1 is a schematic diagram of a DMR TDMA frame structure in a private network mode. As shown in fig. 1, a DMR TDMA frame includes two time slots (two logical channels), each time slot being 30ms in length. The base station broadcasts a CACH burst between two logical channels when broadcasting signals on the downlink channel.
Currently, the format of CACH signaling based on CACH burst transmission defined in DMR standard is shown in fig. 1, each CACH signaling has 24 bits, and specifically includes 1-bit AT (Access Type) information element, 1-bit TC (TDMA Channel) information element, 2-bit lcs (Link control Start/end) information element, 3-bit FEC (Forward Error Correction) information element, and 17-bit information element for carrying data.
It should be noted that the AT information unit indicates whether the next uplink channel timeslot is busy or free, the TC information unit indicates whether the next uplink and downlink channel burst is channel 1 or channel 2, and the LCs information unit indicates whether an LC (Link Control) signaling Block or a CSBK (Control signaling Block) included in the CACH burst is a start Block, an end Block, or an intermediate Block. Specific definitions can be found in the several tables below.
Table 9.23：Access Type information element content
Table 9.24：TDMA Channel information element content
Table 9.20：LC Start/Stop information element content
Short LC (Link Control) signaling is used to indicate compressed call destination address information and service types carried by TDMA logical channel 1 and logical channel 2, including 28-bit information fields, and currently, an implementation of carrying short LC signaling based on CACH bursts is described in the DMR standard, and is specifically shown in fig. 2. As can be seen from fig. 2, one complete short LC signaling requires 4 CACH bursts to carry.
It can be seen that in the current DMR standard, CACH bursts only support the use of fixed 4 consecutive bursts for carrying 28-bit short LC (Link Control) signaling. If the base station needs to issue the short signaling with less than 28 bits, it also needs to use fixed continuous 4 CACH bursts to carry the short signaling, and if the base station needs to issue the short signaling with more than 28 bits, it cannot be realized based on the CACH bursts, so in the current DMR standard, the use mode of the CACH bursts is not flexible enough.
The inventor of the present application finds, through intensive research, that a manner of selecting different numbers of CACH bursts to be combined and transmitted based on the size of data to be carried can solve the problem that the use manner of CACH bursts is not flexible enough in the current DMR standard.
To achieve the above object, in the present application, a format of CACH signaling based on CACH burst transmission is redefined, please refer to fig. 3, fig. 3 is a schematic diagram of a format of the redefined CACH signaling disclosed in this embodiment of the present application, and as shown in fig. 3, the redefined CACH signaling includes 24 bits, specifically includes a 1-bit AT (Access Type) information unit, a 1-bit TC (TDMA Channel) information unit, a 2-bit lcs (Link Control Start/Stop) information unit, a 3-bit FEC (Forward Error Correction) check information, a 12-bit information unit for carrying data, and a 5-bit check information unit. The 12-bit information unit for carrying Data includes a start stop (StartStop) flag information unit SS, a Multi-combination CACH block number indication information unit Multi-CACH Num Ind and a User Data information unit User Data. The value in the 5-bit check information unit is check information for performing error correction and detection protection on the carried data. In the application, Hamming (17,12,3) coding can be adopted to carry out FEC error correction and detection protection on the carrying data.
It should be noted that, in the newly defined CACH signaling format in the present application, the value of the lcs information element is 0, which is specifically shown in table 1 below.
TABLE 1
In addition, in the newly defined CACH signaling format in the present application, a start-stop flag information unit, a multiple-combination CACH block number indication information unit, and a user data information unit are defined, where a value of the start-stop flag information unit is used to indicate whether the carried data is a start-stop block of all service data to be transmitted, a value of the multiple-combination CACH block number indication information unit is used to indicate arrangement number information of the carried data in all service data to be transmitted, and the user data information unit is used to carry data.
For convenience of understanding, when the value of the start-stop flag information element is 1 and the value of the multi-combination CACH block number indication information element is 0, it indicates that the data carried by the CACH signaling is all of all the service data to be transmitted. When the value of the start-stop flag information unit is 0, it indicates that the data carried by the CACH signaling is the first block of all the service data to be transmitted. When the value of the start-stop mark information unit is 0 and the value of the multi-combination CACH block number indication information unit is not 0, the CACH signaling carried data is the middle block of all service data to be transmitted. When the value of the start-stop mark information unit is 1 and the value of the multi-combination CACH block number indication information unit is not 0, the data carried by the CACH signaling is the last block of all service data to be transmitted.
Based on the redefined CACH signaling format, in the present application, service data of different sizes may be transmitted in a CACH burst combination manner. For example, defining 12-bit information units for carrying data to include a 1-bit start/stop (StartStop) flag information unit, a 3-bit multi-combination CACH block number indication information unit, and an 8-bit user data information unit, it is possible to realize flexible combination of 1 to 8 CACH bursts to transmit different sizes of traffic data.
For convenience of understanding, in the present application, examples of definitions of a start-stop flag information unit, a multi-combination CACH block number indication information unit, and a user data information unit when 1 to 8 CACH bursts are flexibly combined are given, and are specifically shown in table 2. In addition, the application also provides 1 to 8 CACH burst flexible combination modes, which are specifically shown in the following table 3.
TABLE 2
TABLE 3
The shortest sending data combination is combination 1, combination 1 comprises 1 CACH burst, can carry 8-bit effective data information, and can complete sending only by 30 ms; the longest transmission data combination is a combination 8, the combination 8 includes 8 CACH bursts, and can carry 64 bits of effective data information, and the 64 bits are enough to carry important control information such as LC header or data information such as GPS (Global Positioning System), and the transmission can be completed only in 240 ms.
It should be noted that, when it is required to carry data information within 28 bits, for better compatibility, the original DMR standard may be used to fix 4 CACH burst combinations.
It should be further noted that the user may redefine the combination manner according to the customized service, and any combination manner based on the above-mentioned idea transformation of the present application is within the protection scope of the present application.
