Fig. 6 shows the schematic diagram of realizing of single many communication speech of TETRA switch recording arrangement, at this notRepeat again.
Fig. 7 shows communication speech recording system that the embodiment of the present invention provides in the time communicating voice collectingData flow, its situation taking many communication speech of Dual-switch recording arrangement is as example, and for convenience of explanation,Only show part related to the present invention.
As seen from Figure 7, control module is as the core of communication speech recording system, with TETRAAPIServer communicates, and gets the relevant call-information in TETRA system, and according to call-information,In the time that TETRA system produces call event, send corresponding control instruction to voice collecting node. Meanwhile,Voice collecting node collects corresponding communication speech by modes such as E1 special lines from TETRA switch,Communication speech with completion system is recorded work.
In above-mentioned flow process, the call event information of TETRA system can be by (any one in this systemPlatform) TETRAAPI server is delivered in (any one) control module of communication speech recording system,Pass through TETRA switch to communication speech by control module control (any one) voice collecting node againGather, and multiple voice collecting nodes in communication speech recording system all can with one or moreTETRA switch is connected, to complete the work of recording of communication speech. Meanwhile, with the system knot in Fig. 7Structure is example, according to different engineering configuration needs, and when share as main purpose taking traffic, voice collecting jointPoint A and B gather the communication speech being assigned to separately independently, when for security reliability consideration,During taking data backup as main purpose, voice collecting node A and B adopt the communication speech of same contentCollection, to realize two-shipper function for subsequent use. Concrete system architecture and trafficwise taking actual requirement of engineering asBasis, in this no limit.
Fig. 8 shows the communication speech of the communication speech recording system that the embodiment of the present invention provides and records workflowJourney, details are as follows:
1, obtain all call group numbers of TETRA system and have the personal terminal number of individual call right.
2, start TETRA system calling event-monitoring.
3,, in the time having call event to occur, judge that this call event is that group calling is also individual exhaling.
4,, in the time that call event is group calling, according to called party's quantity of group calling, distribute the voice of respective numbersDistribution channel for distribution; In the time that call event is individual exhaling, for calling party and the callee of call event distribute respectively correspondingVoice distribution channel for distribution.
5, send voice collecting instruction.
6, start to communicate voice collecting.
7, send and stop voice collecting instruction.
8, stop communicating voice collecting.
9,, after call event finishes, recover the monitor state to call event
In embodiments of the present invention, above-mentioned steps 8 also can be carried out after step 9, when call event knotShu Hou, then voice collecting node is sent and stops accordingly voice collecting instruction, concrete restriction do not done at this.
In embodiments of the present invention, communication speech recording system, based on computer network, passes through TETRAAPIServer docks with TETRA system, and the call event of whole TETRA system is monitored. WhenWhile having call event to occur, according to the type of call event, the corresponding voice distribution channel for distribution of dynamic assignment is given notSame voice collecting node, realizes and recording for the communication speech of TETRA system whole-network, and control moduleSeparately dispose with voice collecting node, realized the online dilatation of system.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, not all at thisAny amendment of doing within bright spirit and principle, be equal to and replace and improvement etc., all should be included in the present inventionProtection domain within.
