At present, the digital trunking communication system mainly applied to command and dispatch still takes a narrow-band private network as a main part, and the narrow-band private network has the advantages of large area system, wide coverage of a single base station, good voice communication and the like, but is limited by a narrow-band technology, and cannot provide multimedia image and video communication functions, whereas the broadband trunking communication can provide multimedia image and video communication functions, so that a wide-band and narrow-band convergence terminal becomes a trend, and the advantages of the wide-band and narrow-band convergence terminal can be mutually complemented and can be suitable for more scenes.
PDT, namely a police digital cluster, is a narrow-band private network technical standard formulated by the lead of the public security department of China. In the past decade, PDT has played a vital role in the business of daily police, security, emergency command, and the like. Pure broadband trunking standards (B-trunk) based on TD-LTE technology are also established in China, and the department of industrial and communication designates 20 megabandwidths (1447-1467 MHz and 1785-1805 MHz) as government broadband private network use frequencies.

Secondly, the implementation mode of the PDT+B-trunk wide and narrow band fusion terminal in the market at present adopts a dual-mode dual-standby single-pass or dual-mode single-standby single-pass mode, namely, PDT or B-trunk mode can only be selected for use at the same time, and wide and narrow bands cannot be used in dual-standby dual-pass mode, so that a plurality of inconveniences are brought to use; and a dual-mode dual-standby dual-pass mode is adopted, but in the concurrent call service of PDT and B-trunk, the excellent fusion conflict processing is not carried out according to the characteristics of trunking call types, and the experience and effect of the actual use of the terminal in the trunking communication process are affected.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
The embodiment provides a realization method for conversation service fusion processing of a broadband fusion terminal, which comprises a narrowband basic supporting part, a broadband basic supporting part, a fusion processing module and a display module, wherein the realization method is shown in figure 1; the broadband base supporting part is interconnected with the narrow-band base supporting part and the fusion processing module, and the fusion processing module is also interconnected with the display module; the narrow-band basic supporting part comprises a PDT radio frequency module, a PDT Modem module and a PDT AT command analysis module which are sequentially connected, and the broadband basic supporting part comprises a B-trunk radio frequency module, a B-trunk Modem module and a B-trunk AT command analysis module which are sequentially connected; by adopting two sets of different radio frequency and Modem modules in PDT narrow band and B-trunk broadband in the terminal, a hardware foundation is provided for dual-mode dual-standby dual-pass of broadband and narrow band service, and a fusion processing module in a software layer is combined, so that dual-mode dual-standby dual-pass of PDT and B-trunk trunking call service is realized.
Specifically, the fusion processing module is interconnected with the PDT AT command analysis module and the B-trunk AT command analysis module and is used for processing the receiving and sending requests of PDT and B-trunk calls and the fusion and unified processing of concurrent services;
The display module is used as a man-machine interaction end and is interconnected with the fusion processing module and used for displaying interfaces of the initiation and the reception of PDT or B-trunk call service and the fusion processing interface of the PDT and B-trunk call concurrent service.
The method of the invention not only ensures the normal condition of single call service of PDT or B-trunk, but also ensures that the conflict of dual-mode dual-standby dual-pass concurrent service is well integrated. The PDT and the B-trunk receive and transmit call requests through respective AT command modules, and the AT commands of different networks are fused together through a wide-narrow band communication service fusion processing module, so that the problem that the AT command systems cannot be uniformly processed is solved, and meanwhile, the problem of call service conflict is solved.
The convergence processing module comprises an AT command interception module, a convergence business conflict processing module and a call service module, as shown in fig. 2; the AT command interception module converts AT call service commands of different network protocols into unified call service commands; the call service module is connected with the converged service conflict processing module and the display module, and is used for processing call service logic of PDT and B-trunk and informing the display module to update the UI; the convergence service conflict processing module is a core module of the broad-narrow band communication service unified processing module and is mainly used for processing service convergence and call conflict logic, the convergence service conflict processing module is connected with the AT command module and the call service module and is used for caching the current network call service, and when the concurrent service encounters a call conflict, the corresponding logic is processed according to a priority mechanism of a call type.
Specifically, the AT command interception module comprises a PDT AT command interception module and a B-trunk AT command interception module, and the PDT AT command interception module converts an AT call service command of a PDT network protocol into a unified call service command and transmits the unified call service command to the fusion service conflict processing module; the B-trunk AT command interception module converts the AT call service command of the B-trunk network protocol into a unified call service command and transmits the unified call service command to the fusion service conflict processing module; the call service module comprises a PDT call service module and a B-trunk call service module, wherein the PDT call service module and the B-trunk call service module are respectively interconnected with the converged service conflict processing module and are also respectively interconnected with the man-machine interaction terminal.
In this implementation scenario, in order to ensure a unified call service command, when the narrowband PDT command analysis module receives an AT command sent by the narrowband Modem module, the AT command is analyzed, then the PDT command interceptor performs filtering, if the AT command is an incoming call command, the AT command is intercepted, and is converted into a unified call service command, and then the call service command is transferred to the converged service conflict processing module for unified processing, and other commands still pass through the original service flow, thereby realizing mutual independence of the original services of the dual-mode dual-standby dual-pass terminal, and simultaneously unifying the call service flow, and providing preconditions for solving the call conflict problem between different networks.
As an implementation scenario, the implementation scenario shows an individual call service processing flow, which specifically includes: after receiving the narrow-band PDT incoming call command, the convergence service conflict processing module judges whether the opposite-end network call is cached currently, if not, the narrow-band PDT call service is cached, PDT call service is created, an incoming call interface is started, and a user waits for answering. And deleting the cached PDT call service after the narrowband PDT call is ended, and recovering to an idle state.
As an implementation scenario, the implementation scenario shows a concurrent call service processing flow, which specifically includes: in the process of narrowband PDT conversation, a broadband B-trunk command analysis module receives an incoming AT command sent by a broadband Modem module, after the AT command is analyzed, the B-trunk command interception module filters the incoming AT command, and intercepts the incoming AT command, converts the AT command of a B-trunk protocol into a unified incoming command and sends the unified incoming command to a fusion service conflict processing module. After receiving the broadband B-trunk incoming call command, the converged service conflict processing module carries out conflict service logic processing when finding that a cache opposite terminal network call exists; therefore, the problem that different AT command systems cannot uniformly judge when the concurrent service is encountered on the basis that the normal operation of the original independent network call service is not affected by the dual-mode dual-standby dual-pass terminal is realized.
The trunking communication comprises a plurality of call types such as voice call, voice group call, video group call, broadcast call, full call, emergency call and the like. A single call is a call established between two terminals; group calling is to initiate a multi-to-multi call in which a plurality of terminals participate by one terminal; an emergency call is a call that a user initiates in an emergency situation. Because the two modes have unsupported call types, such as PDT does not have video call types, for convenience in processing, the embodiment uniformly classifies the calls between the two terminals as single calls according to the call characteristics, wherein the single calls comprise voice single calls and video single calls; the calls participated by a plurality of terminals are grouped into group calls in a unified way, wherein the group calls comprise voice group calls and video group calls, and whole calls and broadcast calls; the emergency call is taken as a single type, and comprises an emergency single call, an emergency group call and the like; in priority ordering, the emergency call > group call > single call, when the system is busy, the high priority call type can preempt the resources of the low priority call type, when the same priority call type of different networks appears, the user can select to answer the call of one network by himself.
The single call and the emergency call are not subdivided in priority, the situation is simple and better to process, but the group call has all calls, broadcast calls and priority calls with different grades, the situation is complex, the calls are not uniformly processed, and the call is difficult to fall to the ground. Therefore, as an implementation scenario, the implementation scenario performs priority limitation on the group call, that is, the priority of the group call is ordered by numbers, the numerical values are arranged from low to high, and the smaller the numerical value is, the higher the priority is;
specifically, the priority ordering of the group call is as follows: full call > broadcast call > priority call > normal group call;
Wherein the priority of the full call is defined as the highest level 0, the priority of the broadcast call is defined as the next highest level 1, the normal call is the lowest priority, and the priority is defined as 65535;
The priority number of the PDT network protocol priority calls is M, and the PDT network protocol priority calls are ordered from high priority to low priority, and the numbers 1-M are taken;
the priority number of the B-trunk network protocol priority calls is N, and the priority numbers are 1 to N according to the priority order from high to low;
The unified priority conversion formula of the PDT network protocol priority call is f (x), wherein x corresponds to the number of the priority, the value range of x is 1-M, 1 is the highest priority, 2 is the next highest priority, and M is the lowest priority;
the unified priority conversion formula of the B-trunk network protocol priority call is g (y), wherein y corresponds to the number of the priority, the value range of y is 1-N, 1 is the highest priority, 2 is the next highest priority, and N is the lowest priority;
the specific group call priority is as follows:
for the above-mentioned M, N cases of correspondence with f (x) and g (y), further explanation is as follows:
1) When m=n=0, it indicates that neither PDT nor B-trunk has priority call, and it is regarded as a normal group call, and its priority conversion values are 65535;
2) When m=0 and n+.0, it indicates that PDT has no priority call (only normal group call), and B-trunk has priority call; then the PDT corresponding priority switch value is 65535 and the b-trunk corresponding priority switch value is constant 2;
3) When M +.0 and n=0, it indicates that there is no priority call for B-trunk when PDT is present (only normal group call); then the PDT corresponding priority switch value is constant at 2 and the b-trunk corresponding priority switch value is 65535;
4) When M is less than or equal to N, namely the PDT priority number is less than or equal to the B-trunk priority number, the PDT corresponding priority conversion value is the priority number plus 1; the corresponding priority conversion value of the B-trunk is divided into two cases, wherein the priority number is added with 1 in the 1-M stage, and the more than M part is always added with 1 in the M stage, and the figure 3 is referred;
5) When M is more than N, namely the number of PDT priorities is more than the number of B-trunk priorities, the priority conversion values corresponding to PDT are divided into two cases, the priority numbers are increased by 1 in the 1-N stages, and the more than N parts are always increased by 1; the corresponding priority conversion value of B-trunk is the priority number plus 1, see FIG. 4;
after unifying call types and priority standards, the PDT and B-trunk wide and narrow-band dual-mode dual-pass terminal has the precondition of fusion processing, and the embodiment designs and formulates the processing criteria of concurrent call in two modes according to the characteristics of the private network cluster communication group call as a main part and high priority and on the premise of ensuring that one call is answered at the same time:
1) Call type priority comparison: emergency call > group call > single call;
2) The user selects to answer the emergency call by himself;
3) Comparing priority with group call: the high priority is higher than the low priority, and the user selects to answer at the same priority;
4) And the user selects answering by himself when the call is singly called.
According to the criterion, all cases of concurrent conversations in two modes can be covered, and processing logic of each case is formulated according to the criteria. The embodiment is mainly described for the incoming call concurrency situation, and the outgoing call concurrency situation can be avoided by the display module, and also can refer to the incoming call situation processing mode, which is not described herein.
When the PDT calls, if there is a B-trunk call, the processing logic is as follows:
When PDT singly calls, B-trunk singly calls, prompts the user, and the user decides whether to answer or not;
When PDT singly calls, B-trunk group calls are called in, PDT singly calls are ended, and B-trunk group calls are responded;
when PDT singly calls, B-trunk emergency call is ended, PDT singly calls are responded, and B-trunk emergency call is responded;
When PDT group call is in progress, B-trunk single call is ended, and missed calls are prompted;
When PDT group call is in communication, B-trunk group call is in, and the B-trunk group call is determined according to the priority;
When PDT group call is communicated, B-trunk emergency call is ended, PDT group call is ended, and B-trunk emergency call is responded;
when PDT emergency call, B-trunk single call is ended, and missed call is prompted;
When PDT emergency call, B-trunk group call is ended, and missed call is prompted;
when PDT emergency call, B-trunk emergency call prompts user, and user decides whether to answer or not.
When the B-trunk calls, if PDT calls in, the processing logic is as follows:
When B-trunk single call is communicated, PDT single call is called in, the user is prompted, and whether answering is carried out or not is determined by the user;
When B-trunk single call is called, PDT group call is called, B-trunk single call is ended, and PDT group call is responded;
when B-trunk single call is communicated, PDT emergency call is ended, B-trunk single call is ended, and PDT emergency call is responded;
When B-trunk group call is in, PDT calls singly are ended, and missed calls are prompted;
when B-trunk group calling is called, PDT group calling is called in, and the PDT group calling is determined according to the priority;
when B-trunk group calling is called, PDT emergency call is ended, B-trunk group calling is ended, and PDT emergency call is responded;
When B-trunk emergency call, PDT calls in, ends PDT calls, prompts missed call;
