Abstract
The present invention discloses a method for controlling colony network multiple-path speech, which is characterized in that a PTT server controls reversal receiving authorities and self upload authorities of mobile terminals from intermediate devices coupled by all mobile terminals in a colony network group through a speaking right granting command, a speaking right occupation command and a speaking right idle command. Therefore, the method realizes that in one PTT colony group, only reversal speech data of the mobile terminal granted with the speaking right can be transmitted to a PTT server through the coupled intermediate devices simultaneously. The method can effectively prevent the reversal speech data of the mobile terminal granted with the speaking right from being interfered by reversal speech data of the mobile terminal which is not granted with the speaking right, and the method can solve the problem that users can not listen in share link speech data caused by miscellaneous speech data on a share link.
Description
Technical field
The present invention relates to trunking communicating technology, particularly relate to a kind of method of controlling colony network multipath sound.
Background technology
Trunked communication system is an indispensable branch of wireless communication system, is one of development focus of moving communicating field in recent years.The implication of trunked communication system is: it is shared that whole available channels that system had all can be all users of system, be intrasystem arbitrary user want with system in another user's communication, as long as idle channel is arranged, just can be under the control of central control board, utilize the idle channel communication links, converse.
Press-and-talk (Push to Talk, PTT) technology is a kind of cluster intercommunication technology, the PTT business refers to direct-connected " point-to-point " and " putting multiple spot " Speech Communication in real time.This professional very simple half-duplex operation mode of using, promptly have only a people to talk at one time, so that colony exchanges, the calling party is as long as just can initiate conversation to a people or lineup by a button, need not dialing and wait for the other side's off-hook, particular talk group is set up in the phone demand working rapidly.Be specially adapted between team, working group, the colony collaborative work with exchange.
PTT is based on the characteristics of " press-and-talk ", access delay there be the demand higher than plain old telephone, simultaneously, because the characteristics of " half-duplex " that itself had communication, generally need to adopt dedicated network or on the basis of original telephone network, transform and realize, develop into special-purpose cluster network.
" half-duplex " of group service communication has the advantages that the same time has only a people to talk, in order to realize people speech, the purpose that many people listen to, generally need talker's speech directly to be dealt into the ptt server of special disposal speech, carry out speech by ptt server and be distributed to each obedient person.Therefore, reverse link synchronization from the portable terminal to the ptt server has only 1 portable terminal using, each bar forward link from the ptt server to the portable terminal also all is to send identical content, in order to reach the saving link circuit resource, improve the purpose of power system capacity, general shared terrestrial links, the purpose of raising the efficiency, reducing cost of realizing in network to reach.
Fig. 1 is a structural representation of realizing the cluster network of PTT business, as can be seen from Figure 1, four users is arranged in certain cluster group, respectively corresponding four travelling carriages (MS): MS1, MS2, MS3 and MS4; Four MS are connected with ptt server by wireless access network (RAN), and wherein MS1 and MS2 insert RAN1, and MS3 and MS4 insert RAN2, and RAN1 is connected with ptt server by a shared channel respectively with RAN2.Because RAN can be integrated entity, also can comprise some entities such as base station controller (BSC) and Packet Control Function (PCF) equipment, institute thinks the differentiation both of these case, in Fig. 1, RAN 1 is integrated entity, and RAN2 comprises BSC2 and PCF2, also connects by shared link between BSC2 and the PCF2.
The professional half-duplex operation mode that adopts of PTT, the MS that the user uses need could be talked by after the ptt server mandate, and after speaking right had been authorized certain MS, ptt server will be notified other MS, avoided other MS blindly to initiate talk request.Equally, after speech discharged, ptt server will be notified all MS speaking right free time, so that MS initiates talk request.Its basic signaling has following several:
1, speaking right is authorized (GRANT) signaling: when MS was awarded with speaking right, ptt server sent this signaling to being authorized to MS, and prompting is authorized to MS and can sends reverse speech.
2, speaking right takies (TAKEN) signaling: when MS was awarded with speaking right, ptt server sent this signaling to other MS, pointed out other MS can not send reverse speech, can not initiate the speaking right request.
3, speaking right free time (IDLE) signaling: when speaking right was regained, ptt server sent all MS of this signaling, pointed out all MS can ask speaking right, but can not send reverse speech before the unauthorized.
Cluster speaking right management process generally comprises above-mentioned three basic signalings, after the user asks speech to obtain the ptt server permission, ptt server issues the MS of GRANT signaling to spoken user, point out it can send reverse voice, ptt server issues the TAKEN signaling to other all MS simultaneously, point out other all MS can not send reverse voice, can not initiate the speaking right request.After user's speaking right was regained, ptt server sent the IDLE signaling to all MS, points out all MS can ask speaking right, but can not send reverse voice.By the state of these three basic signaling prompting MS, realize that ptt server oppositely sends the control of voice to MS.
Shared link has been saved Internet resources, and the problem of bringing is the hidden danger that reverse link exists multichannel to converge, though prior art has three its residing states of signaling prompting MS, but does not have the control measure of essence to forbid that undelegated MS sends reverse voice.Like this, may exist a plurality of MS to send reverse speech data via RAN to ptt server simultaneously, also just might cause oppositely to exist multi-path voice to upload simultaneously, cause that shared link section voice data mixes, and causes the user can't monitor these voice.

Embodiment
In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention is further described below in conjunction with the drawings and specific embodiments.
Method of the present invention is to realize controlling reverse multi-path voice by revising three basic signalings, article three, signaling not only is used to point out the state of MS, also to signaling the intermediate equipment of process be provided with, by the control intermediate equipment receive the authority of MS and self on transmit the reverse multi-path voice of control.
Specific embodiment one:
Present embodiment is an example with network configuration shown in Figure 1, and Fig. 2 is the method flow diagram of present embodiment control colony network multipath sound, and as can be seen from Figure 2, this method comprises the steps:
Step 201: the function that three basic signalings in the PTT business are set:
The GRANT signaling: when MS was awarded with speaking right, ptt server sent this signaling to being authorized to MS, and prompting is authorized to MS and can sends reverse speech; Simultaneously, open the reverse reception authority of the intermediate equipment of signaling process, but the upload permissions of this intermediate equipment is not done qualification signaling purpose MS.
The TAKEN signaling: when MS was awarded with speaking right, ptt server sent this signaling to other MS, pointed out other MS can not send reverse speech, can not initiate the speaking right request; Simultaneously, close the reverse reception authority of the intermediate equipment of signaling process, but the upload permissions of this intermediate equipment is not done qualification signaling purpose MS.
The IDLE signaling: when speaking right was regained, ptt server sent all MS of this signaling, pointed out all MS can ask speaking right, but can not send reverse speech before the unauthorized; Simultaneously, close the reverse reception authority of the intermediate equipment of signaling process, but the upload permissions of this intermediate equipment is not done qualification signaling purpose MS.
The method of present embodiment is only controlled the reverse reception authority of intermediate equipment to MS, and does not control the upload permissions of intermediate equipment self.
Step 202: cluster is set up immediately, and before user's speech, ptt server sends the IDLE signaling to the interior all users of group, promptly sends the IDLE signaling to RAN1 and RAN2.
Step 203:RAN1 closes the reverse reception authority to IDLE signaling purpose-MS1 and MS2, and the IDLE signaling is sent to MS1 and MS2; BSC2 among the RAN2 closes the reverse reception authority to IDLE signaling purpose-MS3 and MS4, and BSC2 is sent to MS3 and MS4 with the IDLE signaling.
Step 204:MS1 sends talk request message to RAN1, and RAN1 transmits this talk request message to ptt server.
Step 205:PTT server judges whether the speaking right of this cluster group is idle, if then forward step 207 to; Otherwise, forward step 206 to.
Step 206: send the speaking right request failure message to RAN1, RAN1 transmits this message to MS1, finishes then.
Step 207: send the GRANT signaling to RAN1, send the TAKEN signaling simultaneously to RAN1 and RAN2.
Step 208:RAN1 opens the reverse reception authority to GRANT signaling purpose-MS1, and the GRANT signaling is forwarded to MS1; RAN1 closes the reverse reception authority to TAKEN signaling purpose-MS2, and the TAKEN signaling is forwarded to MS2; BSC2 among the RAN2 closes the reverse reception authority to TAKEN signaling purpose-MS3 and MS4, and the TAKEN signaling is forwarded to MS3 and MS4.
Step 209:MS1 begins speech, and speech data is sent to RAN1 by backward channel, and RAN1 transmits this speech data to ptt server.
Step 210:MS1 speech finishes, and sends the speaking right release message to RAN1, and RAN1 transmits this speaking right release message to ptt server.
Step 211:PTT server sends the IDLE signaling to RAN1 and RAN2.
Step 212:RAN1 closes the reverse reception authority to IDLE signaling purpose-MS1 and MS2, and the IDLE signaling is forwarded to MS1 and MS2; BSC2 among the RAN2 closes the reverse reception authority to IDLE signaling purpose-MS3 and MS4, and the IDLE signaling is forwarded to MS3 and MS4.
Because RAN1 closes the reverse reception authority to MS2, so RAN1 does not receive the reverse speech data of MS2; Because the BSC2 of RAN2 closes the reverse reception authority to MS3 and MS4, so RAN2 does not receive the reverse speech data of MS3 and MS4.Like this, only have the purpose MS of GRANT signaling to be received, and other MS can not be received by intermediate equipment, so avoided the situation of reverse multi-path voice by intermediate equipment.But, in some cases,, also may cause RAN to upload to the ptt server mistake if RAN breaks down, because present embodiment has only limited the reverse reception of RAN, do not limit uploading of RAN, so present embodiment can not be avoided this problem.
Specific embodiment two:
Present embodiment is an example with network configuration shown in Figure 1, and Fig. 3 is the method flow diagram of present embodiment control colony network multipath sound, and as can be seen from Figure 3, this method comprises the steps:
Step 301: the function that three basic signalings in the PTT business are set:
The GRANT signaling: when MS was awarded with speaking right, ptt server sent this signaling to being authorized to MS, and prompting is authorized to MS and can sends reverse speech; Simultaneously, open the upload permissions of the intermediate equipment of signaling process, but do not change the reverse reception authority of this intermediate equipment MS.
The TAKEN signaling: when MS was awarded with speaking right, ptt server sent this signaling to other MS, pointed out other MS can not send reverse speech, can not initiate the speaking right request; Simultaneously, do not change the upload permissions of the intermediate equipment of signaling process, but do not change the reverse reception authority of this intermediate equipment MS.
The IDLE signaling: when speaking right was regained, ptt server sent all MS of this signaling, pointed out all MS can ask speaking right, but can not send reverse speech before the unauthorized; Simultaneously, close the upload permissions of the intermediate equipment of signaling process, but do not change the reverse reception authority of this intermediate equipment MS.
The method of present embodiment is only controlled the upload permissions of intermediate equipment self, and does not control the reverse reception authority of intermediate equipment to MS.
Step 302: cluster is set up immediately, and before user's speech, ptt server sends the IDLE signaling to the interior all users of group, promptly sends the IDLE signaling to RAN1 and RAN2.
Step 303:RAN1 closes upload permissions, and the IDLE signaling is sent to IDLE signaling purpose-MS1 and MS2; RAN2 closes the upload permissions of BSC2 and PCF2, and BSC2 is sent to IDLE signaling purpose-MS3 and MS4 with the IDLE signaling.
Step 304:MS1 sends talk request message to RAN1, and RAN1 transmits this talk request message to ptt server.
Step 305:PTT server judges whether the speaking right of this cluster group is idle, if then forward step 307 to; Otherwise, forward step 306 to.
Step 306: send the speaking right request failure message to RAN1, RAN1 transmits this message to MS1, finishes then.
Step 307: send the GRANT signaling to RAN1, send the TAKEN signaling simultaneously to RAN1 and RAN2.
Step 308:RAN1 opens upload permissions, and the GRANT signaling is forwarded to MS1, and the TAKEN signaling is forwarded to MS2; BSC2 among the RAN2 is forwarded to MS3 and MS4 with the TAKEN signaling.
Step 309:MS 1 begins speech, and speech data is sent to RAN1 by backward channel, and RAN1 transmits this speech data to ptt server.
Step 310:MS1 speech finishes, and sends the speaking right release message to RAN1, and RAN1 transmits this speaking right release message to ptt server.
Step 311:PTT server sends the IDLE signaling to RAN1 and RAN2.
Step 312:RAN1 closes upload permissions, and the IDLE signaling is forwarded to MS1 and MS2; RAN2 closes the upload permissions of BSC2 and PCF2, and BSC2 is forwarded to MS3 and MS4 with the IDLE signaling.
The advantage of present embodiment is and can effectively controls because the fault of RAN itself produces the situation that mistake is uploaded by the upload permissions of control RAN, solved the defective that exists among the embodiment one.And when the cluster group was crossed over a plurality of RAN, the effect of the method for present embodiment was more obvious.But, because RAN2 closes upload permissions, so RAN2 can not upload the speech data that MS3 and MS4 send; RAN1 opens upload permissions, so RAN1 can upload the speech data that MS1 and MS2 send, so the MS that present embodiment can not avoid sharing same intermediate equipment uploads the situation of speech data simultaneously.
Specific embodiment three:
Present embodiment is an example with network configuration shown in Figure 1, and Fig. 4 is the method flow diagram of present embodiment control colony network multipath sound, and as can be seen from Figure 4, this method comprises the steps:
Step 401: the function that three basic signalings in the PTT business are set:
The GRANT signaling: when MS was awarded with speaking right, ptt server sent this signaling to being authorized to MS, and prompting is authorized to MS and can sends reverse speech; Simultaneously, open the reverse reception authority of the intermediate equipment of signaling process, and open the upload permissions of RAN1 signaling purpose MS.
The TAKEN signaling: when MS was awarded with speaking right, ptt server sent this signaling to other MS, pointed out other MS can not send reverse speech, can not initiate the speaking right request; Simultaneously, close the reverse reception authority of the intermediate equipment of signaling process, but do not change the upload permissions of the intermediate equipment of signaling process signaling purpose MS.
The IDLE signaling: when speaking right was regained, ptt server sent all MS of this signaling, pointed out all MS can ask speaking right, but can not send reverse speech before the unauthorized; Simultaneously, close the reverse reception authority of the intermediate equipment of signaling process, and close the upload permissions of the intermediate equipment of signaling process signaling purpose MS.
The method of present embodiment is not only controlled the upload permissions of intermediate equipment self, also controls the reverse reception authority of intermediate equipment to MS.
Step 402: cluster is set up immediately, and before user's speech, ptt server sends the IDLE signaling to the interior all users of group, promptly sends the IDLE signaling to RAN1 and RAN2.
Step 403:RAN1 closes the reverse reception authority to IDLE signaling purpose-MS1 and MS2, and closes upload permissions, then the IDLE signaling is sent to MS1 and MS2; BSC2 among the RAN2 closes the reverse reception authority to IDLE signaling purpose-MS3 and MS4, and the BSC2 among the RAN2 and PCF2 close upload permissions, and BSC2 is sent to MS3 and MS4 with the IDLE signaling then.
Step 404:MS1 sends talk request message to RAN1, and RAN1 transmits this talk request message to ptt server.
Step 405:PTT server judges whether the speaking right of this cluster group is idle, if then forward step 407 to; Otherwise, forward step 406 to.
Step 406: send the speaking right request failure message to RAN1, RAN1 transmits this message to MS1, finishes then.
Step 407: send the GRANT signaling to RAN1, send the TAKEN signaling simultaneously to RAN1 and RAN2.
Step 408:RAN1 opens the reverse reception authority to GRANT signaling purpose-MS1, and opens upload permissions, and the GRANT signaling is forwarded to MS1; RAN1 closes the reverse reception authority to TAKEN signaling purpose-MS2, and the TAKEN signaling is forwarded to MS2; BSC2 among the RAN2 closes the reverse reception authority to TAKEN signaling purpose-MS3 and MS4, and the TAKEN signaling is forwarded to MS3 and MS4.
Step 409:MS1 begins speech, and speech data is sent to RAN1 by backward channel, and RAN1 transmits this speech data to ptt server.
Step 410:MS1 speech finishes, and sends the speaking right release message to RAN1, and RAN1 transmits this speaking right release message to ptt server.
Step 411:PTT server sends the IDLE signaling to RAN1 and RAN2.
Step 412:RAN1 closes the reverse reception authority to IDLE signaling purpose-MS1 and MS2, closes upload permissions, and the IDLE signaling is forwarded to MS1 and MS2; BSC2 among the RAN2 closes the reverse reception authority to IDLE signaling purpose-MS3 and MS4, close the upload permissions of BSC2 and PCF2, and BSC2 is forwarded to MS3 and MS4 with the IDLE signaling.
Because when ptt server mandate MS1 talked, RAN1 opened the reverse reception authority to MS1, and closes the reverse reception authority to MS2, RAN1 opens upload permissions simultaneously; RAN2 closes the reverse reception authority to MS3 and MS4, and simultaneously RAN2 closes upload permissions, so RAN1 can receive and upload the speech data that MS1 sends, can not receive the speech data that MS2 sends, and RAN2 can not receive the speech data that MS3 and MS4 send.The advantage of present embodiment is reception that can be by the control intermediate equipment and uploads that two kinds of authorities are avoided uploads the reverse multi-path voice that causes because MS mistake is uploaded with the RAN mistake.
In three embodiment of the present invention, initiate talk request by MS1, in fact, can initiate talk request by arbitrary MS in the cluster group, for example, can initiate talk request, step and no change that the present invention handles by MS3.
In three embodiment of the present invention, GRANT denoting signaling speaking right is authorized signaling, TAKEN denoting signaling speaking right occupied signaling, the idle signaling of IDLE denoting signaling speaking right, in fact, but speaking right is authorized, is taken and the title of idle signaling is not limited only to GRANT, TAKEN and IDLE, can also adopt other title.
It should be noted that in an embodiment of the present invention the cluster group only comprises two RAN, in fact, the RAN quantity that the cluster group comprises can be one or more, and the MS that each RAN connects also can be one or more.Equally, the RAN in the method according to this invention also is not limited to two kinds of RAN types shown in Figure 1, but can comprise all types of RAN that are applicable to the PTT business.
In concrete implementation process, can carry out suitable improvement, to adapt to the concrete needs of concrete condition to the method according to this invention.Therefore be appreciated that; just play an exemplary role according to the specific embodiment of the present invention; not in order to restriction protection scope of the present invention; for example; the present invention not only can be applied to the situation that backward channel is shared; under the unshared situation of backward channel, also can use the present invention, transmit reverse speech data via intermediate equipment to ptt server to avoid undelegated portable terminal.
