Specific embodiment

Below with reference to attached drawing, various embodiments of the present invention are further described in detail.

Referring to Fig. 1, in one embodiment, a kind of voice resource distribution method, comprising the following steps:

Step 110, gateway receives voice service request.

Dispatching desk can may also listen for the calling that terminal is carried out with calling terminal, correspondingly, the language initiated by dispatching desk Sound business request includes exhalation request, media monitoring request and signaling monitoring request.

Specifically, exhalation request is dispatching desk request call terminal, media monitoring request is dispatching desk request to terminal Media monitoring is carried out, signaling monitoring request is that dispatching desk request carries out signaling monitoring to terminal.Wherein, calling terminal and to terminal Media monitoring is carried out to need to occupy voice resource.

Terminal can call another terminal, can also be with call scheduling platform, correspondingly, by the voice service request of terminal initiation It is requested including incoming call.

Specifically, needing to occupy voice resource if incoming call request is terminal request call scheduling platform.If incoming call is requested That terminal request calls another terminal, then only when dispatching desk requests to carry out media monitoring to the terminal or another terminal Voice resource can be occupied.

Initiate voice service request in dispatching desk or terminal, and using IP by the voice service request be sent to gateway it Afterwards, gateway is ready to receive arrives voice service request.

Since IP is not limited to voice resource, in synchronization, the voice service request that gateway receives may More than one, i.e. gateway will receive one even more than voice service request.

Step 130, in leisureless voice resource, the type of voice service request is judged, if voice service request is Exhalation request or media monitoring request, then responded by distributing by the voice resource that media monitoring occupies, and return to sound Answer message to dispatching desk.

Wherein, response message is to notify dispatching desk gateway to the response results of voice service request.Specifically, response The content information difference carried in message indicates the different response results of gateway.

For example, if the monitoring rank carried in response message is media monitoring, then it represents that gateway has been media monitoring request It is successfully assigned with voice resource, dispatching desk can realize the media monitoring to terminal by the voice resource.If in response message It has carried and has exhaled error code, then it represents that gateway distributes failure to the voice resource of exhalation request, and dispatching desk is to terminal originated calls Failure.

Should be appreciated that voice resource idle if it exists, then gateway can directly be allocated idle voice resource, And returning response message is to dispatching desk, to respond received voice service request.

And when voice resource is without the free time, in the present embodiment, gateway will be by seizing the voice occupied by media monitoring money Source responds voice service request.

Further, in order to guarantee ongoing voice service before new voice service does not interfere with, not institute Some voice service requests all allow to seize the voice resource occupied by media monitoring, therefore, occupied by media monitoring Voice resource distribution when, gateway will correspondingly seize processing according to the type of voice service request.

It for example, include exhalation request, media monitoring request and signaling prison in the voice service request that gateway receives Listen request.It needs to occupy voice resource due to calling terminal and to terminal progress media monitoring, and signaling monitoring is carried out to terminal It does not need to occupy voice resource, therefore, in leisureless voice resource, gateway will be exhalation request and media monitoring request point With the voice resource occupied by media monitoring, and voice resource authentication is not made to signaling monitoring request, i.e., without any voice The distribution of resource.

It is noted that in the present embodiment, matchmaker that the calling terminal and dispatching desk that dispatching desk is initiated carry out terminal Body monitoring can only be seized to by the occupied voice resource of media monitoring, and cannot be provided to occupied voice is called Source is seized, and guarantees the user experience of voice calls business with this.

Step 150, to be allocated to finish, if returning to carrying there are still the media monitoring not responded request and monitoring rank For signaling monitoring response message to the dispatching desk.

It is assigned in the voice resource occupied by media monitoring, i.e., voice resources all at this time is occupied by calling , for example, being occupied when dispatching desk calling terminal, alternatively, being occupied when terminal call dispatching desk.Due to calling occupied voice money Source can not be preempted, at this point, the voice service request not responded will be unable to be assigned to voice resource.

Based on this, in the present embodiment, when without distributable voice resource, gateway will be by not needing to occupy voice The signaling monitoring of resource further responds the media monitoring request in the voice service request not responded.

Specifically, being requested for exhalation, since without distributable voice resource, gateway return, which has carried, exhales mistake The response message of code is to dispatching desk, to notify the distribution failure of dispatching desk voice resource, correspondingly, the failure of dispatching desk calling terminal.

Media monitoring to be requested, gateway will monitor the adjustment of rank, i.e., signaling monitoring is adjusted to by media monitoring, And monitor rank to carry and as the response message of signaling monitoring be back to dispatching desk, so that the monitoring that dispatching desk carries out terminal is not Voice resource must be occupied again, with this to media monitoring request responded so that user by dispatching desk to terminal into Capable signaling monitoring has still ensured that monitoring of the user to terminal, has avoided although specific call contents can not be listened to The demand of user is unable to satisfy, to improve the experience of user.

Voice service request is still proceeded to respond in no idle speech resource by process as described above, so that with The demand at family is satisfied, and is conducive to user in dispatching desk to the monitored object implementing monitoring such as terminal, to be effectively promoted The experience of user.

In one embodiment, before step 110, method as described above is further comprising the steps of:

Terminal is monitored in dispatching desk request call terminal or request, to be correspondingly formed voice service request, concurrently It send and is formed by voice service request to server, the voice service request received is forwarded to gateway by server.

Wherein, dispatching desk then correspondingly initiates exhalation request to terminal originated calls, and dispatching desk carries out media prison to terminal It listens and then correspondingly initiates media monitoring request, dispatching desk carries out signaling monitoring to terminal and then correspondingly initiates signaling monitoring request.

Referring to Fig. 2, in one embodiment, before step 110, method as described above is further comprising the steps of:

Step 210, server receives the voice service request that dispatching desk issues.

After dispatching desk initiates voice service request, the voice service request will be forwarded by server, in turn It enables the server to receive the voice service request that dispatching desk is initiated.

Step 230, when voice service request is exhalation request, forwarding exhalation request to gateway.

If voice service request is exhalation request, server will directly forward the exhalation to request to gateway, to pass through gateway Exhalation request is responded, as exhalation request distribution voice resource realizes calling that dispatching desk initiates terminal.

Step 250, when voice service request is that media monitoring is requested or signaling monitoring is requested, media monitoring is requested Or signaling monitoring request carries out monitoring pretreatment.

If voice service request is that media monitoring is requested or signaling monitoring is requested, server is before making requests forwarding Request will be monitored to those and carry out monitoring pretreatment, and for example, monitoring pretreatment includes request filtering, avoid dispatching desk from repeating with this Monitoring request is issued to gateway, the treating capacity of gateway is thereby reduced, improves the working efficiency of gateway.

Further, referring to Fig. 3, in one embodiment, step 250 the following steps are included:

Step 251, server judges whether dispatching desk has been monitored terminal according to history monitoring information.

Wherein, terminal is the eavesdropping target of dispatching desk request monitoring in media monitoring request or signaling monitoring request.

Dispatching desk will receive before successfully implementing media monitoring or signaling monitoring to terminal and pass through service by gateway The response message that device returns.Wherein, carrying monitoring rank is the response message of media monitoring to notify dispatching desk to terminal Media monitoring success, carry monitor the response message that rank is signaling monitoring be used to notifying dispatching desk to the signaling monitoring of terminal at Function.

In other words, before dispatching desk receives response message, server will first receive the response message, Jin Ertong Cross memory response message history of forming monitoring information.The history monitoring information is the sound for carrying and monitoring that rank is media monitoring It answers message or carries the response message for monitoring that rank is signaling monitoring.

Based on this, server can know which kind of dispatching desk carried out to which terminal and monitored according to history monitoring information The monitoring of rank, further to realize the monitoring pretreatment to media monitoring request and signaling monitoring request.

If judgement obtains dispatching desk and is monitored terminal, then it represents that gateway need not repeat distribution voice resource, 253 are entered step, with history monitoring information voice responsive service request.

If judgement obtains dispatching desk and do not carry out any monitoring to terminal, 255 are entered step, to distribute voice by gateway Resource is forwarded to the voice service request of gateway to respond.

Certainly, in other application scenarios, server can be combined with monitoring whether priority further judges dispatching desk Terminal is monitored.

Specifically, monitoring priority of the priority higher than signaling monitoring that priority is set as media monitoring.

If the voice service request that dispatching desk newly issues is media monitoring request, and history monitoring information is to carry monitoring Rank is the response message of signaling monitoring, then is considered as dispatching desk and does not monitor the terminal, and then enter step 255, by taking Business device forwarding media monitors request to gateway.

If the voice service request that dispatching desk newly issues is signaling monitoring request, and history monitoring information is to carry monitoring Rank is the response message of media monitoring, then is considered as dispatching desk and is monitored the terminal, and then enter step 253, with History monitoring information responds signaling monitoring request.

Step 253, history monitoring information is returned to dispatching desk.

For example, history monitoring information is to carry the response message for monitoring that rank is signaling monitoring, the history monitoring information It reflects dispatching desk and signaling monitoring has been carried out to a certain terminal, then when server receives dispatching desk request to the terminal again When carrying out the signaling monitoring request of signaling monitoring, dispatching desk directly will be back to the history monitoring information, to respond the signaling Monitor request.

Step 255, to the request of gateway forwards media monitoring or signaling monitoring request.

Referring to Fig. 4, in one embodiment, before step 130, method as described above is further comprising the steps of:

Step 310, gateway judges the calling pair for initiating the terminal of incoming call request when voice service request is that incoming call is requested As if no is dispatching desk.

It should be appreciated that when initiating the call object of terminal of incoming call request is dispatching desk, if gateway has received the end The incoming call request that end is initiated, then it represents that idle voice resource has been allocated into function, and terminal can occupy the voice money of the free time Source initiates to call to dispatching desk, and gateway can terminate voice resource allocation.

And when initiating the call object of terminal of incoming call request is another terminal, only request in dispatching desk to the terminal Or another terminal, when carrying out media monitoring, gateway just needs to carry out voice resource distribution, otherwise will also terminate voice resource Distribution.

Based on this, when the voice service request that gateway receives is that incoming call is requested, in order to know whether to need to carry out down The voice resource of one step distributes, and will judge the call object for the terminal for initiating incoming call request.

If call object is dispatching desk, terminate voice resource allocation, otherwise, if call object is another terminal, into Enter step 330 to make to judge in next step.

Step 330, it when the call object of terminal is another terminal, further determines whether to receive what dispatching desk issued Media monitoring request, media monitoring request are that dispatching desk request carries out media to any terminal in terminal or another terminal What monitoring issued.

If dispatching desk request carries out media monitoring to any terminal in terminal or another terminal, it will issue media prison Listen request to gateway, so that gateway can receive media monitoring request.

Further, it is requested when gateway has received the media monitoring that dispatching desk issues, if it exists idle voice resource, The voice resource of the free time is then directly distributed to respond media monitoring request, conversely, if leisureless voice resource, returns Step 130 is responded to step 150 with the request to the media monitoring.

Referring to Fig. 5, in one embodiment, step 130 the following steps are included:

Step 131, gateway judges whether there is voice resource and is occupied by media monitoring.

Before the voice resource distribution occupied by media monitoring, gateway can sentence the occupant of voice resource It is disconnected, for example, occupant can be calling or media monitoring, the voice resource distribution for being confirmed whether to can be carried out next step with this.

If judging to obtain, there are the occupants of voice resource as media monitoring, enters step 133, carries out by media monitoring The distribution of the voice resource of occupancy.

If judgement is obtained there is no the voice resource occupied by media monitoring, i.e., the occupant of all voice resources is to exhale It cries, then it represents that 150 are entered step, with further without distributable voice resource, i.e. voice resource distribution failure at this time Media monitoring request is responded.

Step 133, cancel media monitoring according to predetermined cancellation rule, to seize the occupied voice money of the media monitoring Source.

How predetermined cancellation rule selects media monitoring to carry out cancellation processing to gateway, and the predetermined rule of cancelling is including taking The longest media monitoring of the listening period that disappears cancels the minimum media monitoring of priority, and certainly, making a reservation for cancel rule can be with It further comprise taking media monitoring the rule cancelled at random.

In the present embodiment, the occupied voice resource of the longest media monitoring of listening period is preferentially preempted, and is guaranteed with this The ongoing voice service of user not will receive the influence that voice resource is seized.

Further, gateway can choose whether to deal with the media monitoring of cancellation, for example, cancelling if not handling Media monitoring directly discharge voice resource, dispatching desk will be interrupted by the monitoring that the media monitoring carries out terminal, conversely, If being handled, the media monitoring of the cancellation can be recorded by server, preferentially to divide in available free voice resource The media monitoring of the dispensing cancellation.

Step 135, the voice resource seized is allocated according to the priority of voice service request, and returning response disappears It ceases to dispatching desk.

The voice service request not responded may be call request, it is also possible to media monitoring request, if gateway is cancelled The longest media monitoring of listening period, then the occupied voice resource of the media monitoring can be distributed to call request or Media monitoring request.

Further, in this embodiment the distribution for the voice resource seized will be according to the preferential grading of voice service request Row, the i.e. high voice service request of priority are preferentially assigned to the voice resource seized.

For example, the priority that call request is arranged in gateway is requested higher than media monitoring, then the voice resource seized Call request preferentially is distributed to, after all call requests not responded have been assigned to voice resource, the voice seized Resource can just be assigned to media monitoring request.

Certainly, in other application scenarios, allocation rule is not limited in carrying out according to the priority of voice service request The distribution for the voice resource seized, can also be and be randomly assigned, alternatively, carrying out according to the sequence that gateway receives voice service request Distribution, i.e., the voice service request that gateway first receives preferentially are assigned to the voice resource seized.

The voice service request for being assigned to voice resource will be by gateway returning response message to dispatching desk, to notify to dispatch The platform gateway success response voice service request.

Further, in one embodiment, method as described above is further comprising the steps of:

Gateway synchronizes the media monitoring of cancellation for signaling monitoring, and returns to synchronous snoop results to server.

In the present embodiment, gateway handles the media monitoring of cancellation, i.e., synchronizes the media monitoring of cancellation for signaling It monitors, so that dispatching desk can continue to be monitored terminal, avoids directly interrupting the experience for monitoring and reducing user.

Further, after the media monitoring of the cancellation is synchronized to signaling monitoring, gateway will be to synchronize snoop results It is back to server.Wherein, synchronous snoop results response message caused by synchronous signaling monitoring forms.

Referring to Fig. 6, in one embodiment, the gateway synchronizes the media monitoring of cancellation for signaling monitoring, and to clothes After the step of business device returns to synchronous snoop results, method as described above is further comprising the steps of:

Step 410, server receives the synchronization snoop results that gateway returns, and is disappeared by extracting response in synchronous snoop results Breath.

It is formed as synchronous snoop results response message caused by the signaling monitoring after synchronizing, at extraction Reason can be signaling prison by synchronizing the monitoring rank carried in the response message for obtaining response message in snoop results, and extracting It listens.

Step 430, by the dispatching desk for obtaining monitoring terminal by the media monitoring of cancellation in history monitoring information, And response message is broadcasted to the dispatching desk.

Since server can know which kind of dispatching desk carried out to which terminal and monitored rank according to history monitoring information Monitoring the dispatching desk monitored by the media monitoring of cancellation terminal therefore can be obtained by history monitoring information.

After obtaining dispatching desk, server can broadcast dispatching desk response message, so that dispatching desk is known The media monitoring of cancellation is synchronized for signaling monitoring, and then carries out subsequent monitoring to terminal in the form of signaling monitoring.

Step 450, history monitoring information is refreshed with response message.

Referring to Fig. 7, in one embodiment, a kind of voice resource distribution method, comprising the following steps:

Step 510, dispatching desk issues voice service request to gateway.

Step 530, the response message that gateway returns is received.

Wherein, response message is gateway in leisureless voice resource, judges the type of voice service request, if voice Service request is exhalation request or media monitoring request, then is responded by distributing by the voice resource that media monitoring occupies It returns.

And/or to be that gateway is to be allocated finish response message, if there are still the media monitoring not responded request, with letter It enables monitoring and response return is carried out to media monitoring request.

In an application scenarios, Fig. 8 to Figure 11 respectively shows signaling monitoring, media in a kind of voice resource distribution method It monitors, the specific implementation process of signaling monitoring and calling interaction, media monitoring and calling interaction.Using MPT wired system as language The limited private network system of sound resource, for dispatching desk 800 issues media monitoring request and signaling monitoring request without repetition, to aforementioned Specific implementation process is illustrated.

It requests as shown in figure 8, dispatching desk 800 sends signaling monitoring to server 900, server 900 is forwarded to MPT gateway 700, it is returned from MPT gateway 700 to dispatching desk 800 and receives success message.
