As shown in Figure 2, these many call conversation right schedulings and voice transmission control method comprise following processing:
Step S202, DAS wherein, comprises in the request of many call conversation rights to many call conversation rights request of DCC forwarding from DAC: dispatcher's information, call information tabulation;
Step S204, DCC checks according to dispatcher's information and call information tabulation whether the request of many call conversation rights is legal; If ask illegally, then flow process finishes;
Step S206, under the legal situation of many call conversation rights request, DCC checks the talking state of each calling in the call information tabulation, and is satisfying under the situation of predetermined condition, proceeds to step S208;
Step S208, DCC authorizes the dispatcher with many call conversation rights of all qualified callings; And
Step S210, the incidence relation of partly setting up between dispatcher and all associated call transmitted in the voice of DCC, and DCC transmits voice packet (wherein, when the dispatcher spoke, DAC transmitted part with the voice of the DCC that voice send) from DAC to the voice link of all associated call.
Afterwards, DCC can notify the result of many call conversation rights of DAC request.
In the present invention, at dispatching control center (DCC), according to current conversation scope difference, the talking state of each calling may be in one of following three kinds of states: idle, unitary call is conversed and many call conversations.Idle condition promptly, if current calling nobody speaks, then is idle for there not being the state of conversation; If conversation is only limited in the call coverage, then be the unitary call conversation; If dispatcher's conversation can be crossed over a plurality of callings (a plurality of call coverage), then be many call conversations.The priority of many call conversations is higher than the unitary call conversation, and the request of many call conversations can be tolled breakdown the unitary call conversation.
According to the difference of talking state, DCC can carry out different processing.If state is idle, conversation power can be authorized the dispatcher, and state exchange is unitary call conversation or many call conversations; If state is the unitary call conversation, this call conversation right can not be seized by other unitary call call request, but can be seized by the request of other many call conversations; If state is many call conversations, then this call conversation right can not be seized by other call request, can only wait for that the dispatcher initiatively discharges conversation power.During unmanned speaking, talking state is recovered idle condition.The dispatcher applies for conversation temporary simultaneously to a plurality of callings, and wherein the talking state of any one calling can not be in many call conversations state, otherwise, the application failure.
Therefore, in step S206, predetermined condition is: the talking state of each calling is idle condition or unitary call talking state in the call information tabulation.If have the calling that is in many call conversations state in the call information tabulation, then flow process finishes.And in step S208, be the calling of idle condition, authorize the dispatcher with many call conversation rights, and talking state is become many call conversations state for talking state; For talking state is the calling of unitary call talking state, discharges conversation power by force, authorizes the dispatcher with many call conversation rights, and talking state is become many call conversations state.
As shown in Figure 3, in step S210, DCC transmits being treated to of voice packet:
Step S302 checks whether voice packet is legal; If illegal, then flow process finishes;
Step S304, under the legal situation of voice packet, according to dispatcher's information of information searching correspondences such as IP address and port numbers in the voice packet, and according to all associated call of dispatcher's information searching; If do not find associated call, then flow process finishes;
Step S306 searches all voice links in the associated call; If do not find voice link, then flow process finishes; And
Step S308 transmits voice packet to all voice links that find.
Further, after the dispatcher discharged many call conversation rights, DAC sent to DCC and discharges many call conversation rights request (wherein comprising dispatcher's information), and DCC can carry out relevant treatment to discharging the request of many call conversation rights.
As shown in Figure 4, the DCC relevant treatment of carrying out comprises:
Step S402 checks whether the request of many call conversation rights of release is legal; If illegal, then flow process finishes;
Step S404 is discharging under the legal situation of many call conversation rights request, according to all associated call of dispatcher's information searching; If do not find, then flow process finishes;
Step S406 discharges many call conversation rights of each associated call that finds, and upgrades the talking state of each associated call; And
Step S408, the incidence relation of partly deleting between dispatcher and all associated call transmitted in the notice voice.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
