Abstract

The present invention discloses a method to send messages, including the following steps: the mobile exchange center receives messages from the message gateway, and further determines whether the intended service user of the messages belongs to a dialing service user or a despatcher of the group service, if no, determines whether the intended service user signs the group service in the located area, if yes, determines whether the current status of the signed group service is in a state of activation, if yes, the mobile exchange center sends a paging information to the base station controller, to command the base station controller to page the intended service user in the service area of the group service which has been signed and currently is in a state of activation; the base station controller pages the intended service user according to the paging information, and sends the messages.

Description

A kind of sending method of note

Technical field

The present invention relates to the communications field, relate to the sending method of a kind of note in trunked communication system especially.

Background technology

Trunking mobile communication is a kind of less expensive of growing up the seventies in 20th century, than the flexible movement communication system, it is the senior developing stage of traditional dedicated radio scheduling net.Traditional dedicated radio dispatching patcher, integrated planning is poor, and model, standard mix, and it is many to net little attitude, and coverage rate is narrow, and in addition noise jamming is serious, the frequency resource waste.Therefore, a kind of new the radio dispatching technique--trunking mobile communication just arises at the historic moment, and is widely applied to traffic, each specialized departments such as public security, highway, fire-fighting, electric power, railway, flood control, finance.

So-called cluster, promptly being to use a plurality of wireless channels is numerous user's services, working method with the telephone trunk line applies in the radio communications system exactly, limited dynamics of channels ground, automatically, rapidly and best all users that distribute to whole system, so that utilize the frequency resource of the channel of whole system to the full extent, its utilization switching technology and computer technology is for whole users of system provide very strong packet capability.We can say that trunked mobile communication system is a kind of special user's program controlled switch technology.

Voice group call service (Voice group call service, abbreviation VGCS), Voice Broadcast Service (VoiceBroadcast Service, be called for short VBS) and the multipriority that strengthens be three kinds of basic services of trunking mobile communication with conversion power (EnhanceMulti-Level Precedence and Pre-emption is called for short eMLPP).Wherein VGCS is the multi-user speech that is implemented in the VGCS zone, can the understand speech business of (hearer's quantity is unrestricted) of more user.

VGCS adopts semiduplex mode to provide professional, VGCS can set up the broadcast ﹠ call of the one group of service-user that belongs to a certain default service area, any service-user can become the speaker during the calling, but any moment only allows speaker's service-user, and other service-user is hearer's service-user.In the VGCS calling procedure, any service-user all can determine to leave midway, perhaps joins during VGCS calls out midway, and the signatory VGCS user who enters the VGCS zone can reception notification, and can determine to join during VGCS calls out midway.

VBS and VGCS are similar, and in default service area, can there be a plurality of users to add VBS and call out, but in whole calling procedure, all the time the user who has only this initiation VBS to call out just can become the speaker, other all users can only monitor, after speech finishes, and the VBS end of calling.In the VBS calling procedure, any hearer user can determine to leave midway, perhaps joins during VBS calls out midway, and the user who enters the VBS zone can reception notification, and can determine to join during VBS calls out midway.

Because the communication means of short message service is convenient, interchange speed is quick, simultaneously.Compare with voice call and to have more flexibility and privacy confidentiality, therefore short message service becomes a basic service of present communication service with one-tenth, point-to-point note is present general a kind of short message communication mode, and point-to-point note is meant the form of service that sends and receive text message between communication terminal.The form of expression of point-to-point note comprises note, international note etc. between note in the net, net.Point in the point-to-point note independent user means of communication of saying so abstractively, this means of communication may be a mobile phone, it also may be a client software, also may be personal digital assistant (Personal Digital Assistant, be called for short PDA) etc. the communication terminal of any signatory short message service, but no matter what this point is, the most basic purposes of point-to-point note is, realizes the mutual interchange between or the multiple spot at 2.

In the prior art, because each user can only take a service channel (TrafficChannel is called for short TCH) in communication network, and the data packet transmission of point-to-point note is transmitted at TCH.

In VGCS or VBS zone, if under VGCS or VBS state of activation, the TCH channel of promptly participating in the user of VGCS or VBS is taken by VGCS or VBS, so, under this kind situation, need carry out the transmission and the reception of point-to-point note, the flow process that service-user terminal and network side need be achieved as follows according to 3GPP agreement regulation:

At first, speaker's service-user or dispatcher for VGCS or VBS receive point-to-point note, configuration according to network side, need take slow associated control channel (the Slow Associated ControlChannel of group calling, be called for short SACCH) or dedicated channel, when the purpose service-user of note was the speaker's service-user of VGCS or VBS or dispatcher, MSC need not paging, and directly adopts supplementary service message to speaker's service-user or dispatcher's transmitting short message.

For hearer's service-user, if a group calling or hearer's service-user of broadcasting need send point-to-point note, this hearer's service-user need withdraw from current group calling of carrying out or broadcasting so, according to 3GPP TS24.011[15] standard, send note, turn back to the group calling answer mode then, general, the process of getting back to group calling or broadcasting after this withdraws from again is very of short duration, can not influence service terminal user's use experience.Receive point-to-point note for VGCS or VBS hearer's service-user, its receiving course is as follows: at base station controller (the Base Station Controller of network side, be called for short BSC) use the flow process of notification message at the group calling passage, or the fast associated control channel of broadcast channel (Fast Associated Control Channel, be called for short FACCH) to group calling, or the broadcast transmission beep-page message (is called in the 3GPP agreement: Paging Information), initiate paging, beep-page message is clear and definite, and to have carried this paging purpose be to send note, and carried this note and will send to which service-user (being the note destination node).After the service-user that is in group calling passage or broadcast channel receives this paging, can respond or not respond, if service-user is selected the response paging, then this service-user need withdraw from group calling or broadcast reception pattern, receive note, after the reception note, return group calling or broadcast mode.General, the process of getting back to group calling or broadcasting after this withdraws from again is very of short duration, can not influence service terminal user's use experience.

In VGCS or VBS zone, this paging and beep-page message are described this in present 3GPP agreement, and be specific as follows:

(the Mobile Switching Center of mobile switching centre, be called for short MSC) receive note from Short Message Service Gateway, parse the purpose service-user number of this note, at Visited Location Registor (Visited LocationRegister, be called for short VLR), the retrieval user VGCS that whether contracted, or VBS business, the structure beep-page message, and this beep-page message is sent to base station system (Base Station System, be called for short BSS), base station controller among the BSS (Base Station Controller, be called for short BSC) according to beep-page message, set up or insert and eat dishes without rice or wine accordingly to connect, in the paging of service-user end side: if signatory VGCS or VBS, and this purpose service-user is not speaker's service-user or the dispatcher of VGCS or VBS, then all VGCS in this service-user position district or the group calling passage of VBS, or the FACCH of broadcast channel goes up the transmission beep-page message.

The structural representation of the beep-page message that sends to BSS from MSC is as shown in Table 1:

Cell	Sending direction	Type	(unit is length: byte)
				Type of message	From MSC to BSS	Motor-driven	1?
International mobile subscriber identifier	From MSC to BSS	Motor-driven	3 to 10
				Short Mobile Station Identifier	From MSC to BSS	Omissible	6?
Cell identification list	From MSC to BSS	Motor-driven	3 to (3+7n)
				The channel that need take	From MSC to BSS	Omissible	2?
The eMLPP priority	From MSC to BSS	Omissible	2?
				Paging information	From MSC to BSS	Omissible	2?

Table one

Wherein in Table 1, the cell identification list in this cell identification list cell this lane place that to be MSC obtain and fill in according to this service-user position district.

Remarks: in Table 1, if in wave point, international mobile subscriber identifier substitutes under the situation of Short Mobile Station Identifier as address of paging, and the Short Mobile Station Identifier cell can be omitted so; If beep-page message does not carry the channel parameter that need take, the value of this channel cell that need take is " 00 " so; If BSS supports the eMLPP strategy, the BSC that then receives beep-page message should use the entrained parameter of ePLMM priority cell to set up wave point; If BSS does not support the eMLPP strategy, BSC can't discern the entrained parameter of ePLMM priority cell so.

At the paging information cell shown in the table one, comprised that MSC knows about how setting up the information specific of paging, the coding of paging information as shown in Table 2:

Table two

By table two as seen, in first bit of second byte of paging information cell, carried a traffic flag bit, be used to indicate the result of MSC according to whether contracted at the VLR retrieval user VGCS or VBS.This traffic flag bit is carried out value, if not signatory any group calling of this note purpose service-user or broadcasting service, so, this traffic flag value is: 0; If signatory certain group calling of this note purpose service-user or broadcasting service, so, this traffic flag value is: 1.

After BSC receives beep-page message,, carry out the purpose service-user of this note of paging at service-user terminal and network side according to the value of the traffic flag bit of the paging information cell in the beep-page message.

One or more VGCS or VBS if the purpose service-user of this note has been contracted, so the cell identification list that will carry according to this beep-page message of BSC in this purpose service-user position district all VGCS or the VBS zone in carry out the note paging.And no matter this VGCS or VBS that whether the purpose service-user of this note contracts.

And simultaneously, because in VGCS or VBS zone, Fast Associated Control Channel (the Fast Associated Control Channel of BSC in VGCS or VBS zone, abbreviation FACCH), dedicated channel (Dedicated Channel, be called for short DCH) or Fast Associated Control Channel (Slow Associated ControlChannel, be called for short SACCH) go up paging, need take the Radio Resource of VGCS or VBS, can to a certain degree influence VGCS or VBS quality.

By last conspicuous, when note purpose service-user in the MSC coverage, one or more VGCS or VBS have contracted, and, this purpose service-user is current when being not the speaker of VGCS or VBS, all that BSC will be in this purpose service-user position district are in the group calling passage of state of activation or the broadcast channel and carry out the note paging so, and whether signatory these VGCS or VBS of the purpose service-user of this note no matter.This note delivery plan has caused all group callings in the lane place or the voice quality of broadcasting service to reduce.

The present invention has following advantage compared with prior art:

By above first technical scheme as can be seen, because the present invention is under the situation of the signatory group service of note purpose service-user, if the signatory group service of this purpose service-user, and, this purpose service-user the current state of signatory group service be state of activation, so, BSC is only at signatory and the current described purpose service-user of group service area paging that is in state of activation.Rather than under the situation of the signatory group service of note purpose service-user, the current state of activation that whether is in of group service no matter this purpose service-user is contracted, BSC is the described note purpose of all the group service area pagings service-user in this purpose service-user position district all.Thereby adopt technical scheme of the present invention, and can be under the situation of the signatory group service of note purpose service-user, avoid influence to the quality of service of signatory VGCS of this service-user in the lane place or VBS.

Further, the present invention is at the signatory group service of this purpose service-user, and this purpose service-user the current state of signatory group service be under the situation of state of activation, BSC is except the signatory and current described purpose service-user of group service area paging that is in state of activation of this note purpose service-user; Simultaneously,,, still guarantee this purpose service-user is paged to arrive, further guaranteed the correct transmission of note even this purpose service-user leaves under the group service situation of being contracted at the described purpose service-user of paging channel paging.

Further, the present invention is at the not signatory group service of purpose service-user, perhaps, the signatory group service of described purpose service-user, but the current state of the group service of being contracted is under the situation of unactivated state, BSC is only at this purpose service-user of paging channel paging, rather than it is of the prior art, VGCS or VBS as long as this purpose service-user has been contracted, and professional current whether activation that no matter should contract, BSC is all at all group service area pagings in this purpose service-user position district, conspicuous, if VGCS or VBS un-activation that this purpose service-user is signatory, adopt so existing technical scheme not only can not the group service zone in the lane place in paging to this purpose service-user, also with in the impact position district, the speech quality with the irrelevant group service of this purpose service-user causes unnecessary interference.

By above second technical scheme as can be seen, the present invention participates in the message that professional service-user carries the characteristic information of unique identification oneself to mobile switching centre's transmission of network side by in group service but make, and reports the incident of " I am in group calling ".Like this, which user what mobile switching centre just can be real-time knows in group calling or broadcasting, and which user has not suffered in group calling or broadcasting.Thereby further make BSC only be accurate in this purpose service-user position district the described note purpose of the group service area paging service-user that just participated in as hearer's service-user, further can not have influence on other any group services in this lane place.

By the 3rd top technical scheme as can be seen, the present invention is at the signatory group service of described purpose service-user, and, the signatory voice group call service of described purpose service-user, or the current state of Voice Broadcast Service is under the situation of state of activation, the signatory and current service identification that is in the group service of state of activation of this note purpose service-user carries at the beep-page message that is used for paging note purpose service-user that sends to BSC in mobile switching centre, make when BSC receives beep-page message, according to entrained service identification, carrying the described note purpose of the collection district service area paging service-user that sign indicates.Rather than prior art, under the situation of the signatory group service of note purpose service-user, BSC is according to being used for the whether value of the flag bit of signatory group service of identification service user in the beep-page message of the prior art, when value indicated the signatory group service of this user, BSC is the described note purpose of all the group service area pagings service-user in this purpose service-user position district all.Thereby adopt technical scheme of the present invention, can be under the situation of the cluster communication service of signatory VGCS of note purpose service-user or VBS, avoid the paging of purpose service-user,, cause the influence of unnecessary voice call quality the not signatory group service of this service-user in the lane place.

Further, whether signatory the present invention increase in beep-page message and be used for recognition purpose service-user group service, perhaps, whether the current state of the group service of being contracted is the cell of unactivated state, value according to cell, when the not signatory group service of purpose service-user, perhaps, the signatory group service of described purpose service-user, but the current state of the group service of being contracted is under the situation of unactivated state, BSC is only at this purpose service-user of paging channel paging, rather than prior art, under the situation of the cluster communication service of signatory VGCS of note purpose service-user or VBS, BSC is according to being used for the whether value of the flag bit of signatory group service of identification service user in the beep-page message of the prior art, when value indicates signatory VGCS of this user or VBS, BSC is paging in all group service zones in this purpose service-user position district all, conspicuous, if the signatory group service current state of this purpose service-user is unactivated state, adopt existing technical scheme not only can not arrive this purpose service-user so at the group service area paging in this lane place, also with in the impact position district with the quality of service of the irrelevant group service of this purpose service-user, cause unnecessary interference.

By above the 4th technical scheme as can be seen, the present invention is by in group service, participate in professional hearer's service-user sends message from the characteristic information that carries unique identification oneself to the mobile switching centre of network side but make, report the incident of " I am in group calling ", which user mobile switching centre can know in real time in group calling or broadcasting, and which user has not suffered in group calling or broadcasting.After thereby mobile switching centre receives point-to-point note, know the current group service that whether participates in of this note purpose service-user, and the service identification of the group service that is participated in, and in beep-page message, carry the service identification of the group service that this purpose service-user participated in, BSC is accurate to just think that this purpose service-user is current when just participating in group service as hearer's service-user, the described note purpose of the group service area paging service-user that this purpose service-user in this purpose service-user position district is participated in further can not have influence on other any VGCS or the VBS that this purpose service-user in this lane place has neither part nor lot in.

Embodiment

Core concept of the present invention provides a kind of sending method of note, this method realizes by following technical scheme, MSC receives note from Short Message Service Gateway, and the purpose service-user sign of described note is obtained in parsing, whether the purpose service-user of judging described note is the speaker's service-user or the dispatcher of group service, if not, then judge the group service in the whether signatory position district of described purpose service-user, if, whether the current state of judging the group service of being contracted is state of activation, if, mobile switching centre sends beep-page message to base station controller, and the indication base station controller is the described purpose service-user of service area paging of the group service of state of activation in described signatory and current state; Base station controller is according to described beep-page message, the described purpose service-user of paging, and send described note.

Further, whether can know at MSC that this purpose service-user is current participates under the situation of group service as hearer's service-user, participate in group service if described purpose service-user is current as hearer's service-user, then MSC sends beep-page message to BSC, and the indication base station controller is at the described purpose service-user of the group service area paging of the current participation of described purpose service-user; Otherwise MSC sends the note beep-page message to BSC, and BSC is in the paging channel paging in indication.

Figure 1 shows that VGCS logical concept schematic diagram, the voice group call service 1 among the figure, voice group call service 2, voice group call service 3 represent to be predefined in the VGCS in the network respectively; The group id (Group ID) that A, B, C, D are illustrated in the network signatory VGCS is respectively the service-user of a, b, c, d; I, II, III, IV are respectively group call region sign (Group call area ID); W, x, y, z are illustrated respectively in the fixing or mobile subscriber who is identified as dispatcher (Dispatcher) in the network.

Understand for those skilled in the art's VGCS business how of the present invention is had generally, the logical concept of VGCS business done detailed explanation below in conjunction with Fig. 1:

L, VGCS call out to be specially and make a calling subscriber or caller dispatcher can be established to targeted customer's voice group call service.Wherein, VGCS is predefined in the network, by group id and group call region sign unique identification.As above the group id among the figure: a and group call region identify: I has identified voice group call service 1.

2, calling subscriber and targeted customer all can be service-user or dispatcher user.

3, the targeted customer refer to be arranged in the VGCS zone by by service-user of exhaling group id to identify or dispatcher user.Target service user should be come " notice " group calling to take place with group id by network, rather than passes through the mode of " paging "; Target dispatcher user should call out by called identification.After service-user enters the VGCS zone, receive corresponding VGCS notice after, can become the target service user.The target service user who leaves the VGCS zone will stop targeted customer's identity.As the party A-subscriber among the group call region sign I among Fig. 1 is the targeted customer of voice group call service 1, and extra-regional party A-subscriber and other user (B, C etc.) are not the targeted customers of voice group call service 1.

4, VGCS calls out and be based upon (the VGCS zone is pre-configured in the network) in the VGCS zone that is made of the sub-district.When service-user is initiated VGCS when calling out, the VGCS zone will be made a call the sub-district, place by service-user and the group id dialed is unique determines.Initiate the dispatcher that VGCS calls out and to be connected to its corresponding VGCS zone, and whether network should identify according to the dispatcher and verify the dispatcher and can make a call.A dispatcher can be preconfigured in a plurality of VGCS callings by network, the dispatcher determines the VGCS of its initiation by travelling carriage International ISDN comprehensive service digital net number (Mobile StationInternational Integrated Services Digital Network Number the is called for short MSISDN) mode that makes a call that contains the VGCS reference.Behind the VGCS call setup, all dispatchers can be switched on, and a VGCS passage all can be set up in each sub-district in the VGCS zone.The group calling passage is a public passage, and the service-user in the sub-district all can be monitored this passage.In the VGCS zone, have only the service-user mobile phone of storage respective sets ID in the SIM card just can join VGCS.When service-user passes through VGCS passage access network, need not and network interaction message, the speed of access is faster than common point-to-point call paging.

5, the VGCS service call only permit at any time 1 speaker's service-user and at the most 5 dispatchers talk simultaneously.Dispatcher user should be able to hear the speech of other speakers except that own, and hearer's service-user can be heard all speaker users' speech.When the dispatcher talked, speaker's service-user should obtain listening indication.The signaling that the dispatcher can talk at any time and need not to add wishes that the service-user of speech then needs additional signaling to indicate it to think speech.When not having speaker's service-user to exist, hearer's service-user just may become speaker's service-user.Service-user obtains the floor according to the mode that gets earlier first, and need not formation.When ringing off, speaker's service-user determine not have speaker's service-user to exist to network indication or network by mechanism such as timer expiries.

If 6 VGCS have set up success, then network should subscriber call, so that the calling subscriber can talk.System should offer the mechanism that service-user becomes the speaker.

The processing of authentication, encryption can be arranged dispatcher and calling business user during 7, VGCS calls out.

The VGCS that 8, in same VGCS zone, can have a plurality of different group ids simultaneously.In different VGCS zones, also can there be the group calling of a plurality of identical group ids simultaneously.

9, the VGCS calling can be by calling business user, and the dispatcher of mandate or network discharge.The caller dispatcher only taken up after, can discharge VGCS.If no voice timer expiry in the VGCS process, network is call release automatically.Service-user and dispatcher also can leaving group-callings and do not influence remainder and continue conversation.The member who leaves VGCS can also return group calling by the mode of dialing group calling.

If 10 service-users (comprising speaker's service-user and hearer's service-user) leave the VGCS zone, then this service-user should leave VGCS, and is unaffected but VGCS still continues.

11, the VGCS service call can be supported roaming.

12, service-user can activate group id, and the information of activation and group identity information are stored in the service-user terminal SIM card together.If there is the group calling of high priority to take place, then the service-user terminal might stop activating group id and leave VGCS.If dispatcher user is simultaneously as service-user and the same group id of having contracted when then this dispatcher user is in the VGCS zone of correspondence, should activate corresponding group id, to avoid dispatcher's the paging and the conflict of notice (containing group id).

When 13, the VGCS zone surpasses the coverage of a MSC, have a plurality of MSC in this group calling, controlling MSC wherein is Anchor MSC, and other MSC are Relay MSC.Anchor MSC is responsible for whole calling, and the data of management have VGCS cell list in VGCS attribute, dispatcher tabulation, Relay MSC tabulation, the Anchor MSC, VGCS Status Flag (whether ongoing).The data that Relay MSC is in charge of have VGCS cell list in the Relay MSC, Anchor MSC sign, VGCS Status Flag (whether ongoing).During a VGCS calls out, a plurality of Relay MSC can be arranged, also can not have Relay MSC.

The VBS system logic structure is similar to VGCS's, and different is in VBS, can only initiate VBS by service-user and call out, and can not the dispatcher initiate the VBS calling, and service-user is successfully initiated, and set up VBS, take voice channel, till this VBS is released always.Simultaneously, VBS can be by having the dispatcher who discharges service-user VBS authority or initiating the calling business user release of this VBS.

Service-user initiates VGCS or VBS calls out, specifically be on travelling carriage, to import group id number by service-user, select VGCS or VBS COS to initiate VGCS or VBS calling, group call region sign (Group Call Area ID) will be initiated VGCS by service-user or VBS calling place cell ID is determined with the group id of being dialed is unique.Group id and group call region sign constitute group call reference or broadcasting determines that with reference to next unique a VGCS or VBS call out, and be as follows:

The group call region sign

Group id

Wherein, the length range of group id is 1～6; VGCS in the unique marked network of group call region sign or VBS zone.

Group call reference or broadcasting is with reference to being made of group id and group call region sign, VGCS in unique marked network or VBS.

VGCS or VBS carry out in the process at VGCS or VBS after setting up, and Qian Yue service-user both can join VGCS or VBS at any time, also can also withdraw from VGCS or VBS at any time, and can not have any impact to ongoing VGCS or VBS.

When VGCS or VBS were in state of activation, when promptly VGCS or VBS carried out in the process, speaker's service-user took proprietary connection, and all hearer's service-users take group-calling channel jointly.

Better understand content of the present invention for the ease of those skilled in the art, below in conjunction with accompanying drawing and specific embodiment to institute of the present invention further instruction.

Embodiment 1:

Figure 2 shows that the method flow diagram of the embodiment of the invention, as shown, the inventive method may further comprise the steps:

Step S200:MSC receives point-to-point note, resolves and obtains note purpose service-user number.

MSC receives point-to-point note from Short Message Service Gateway, and according to received note, resolves the purpose service-user number that obtains this note.

Whether signatory step S201:MSC inquire about this service-user VGCS or VBS.

According to purpose service-user number, the purpose service-user present position district sign of this note of retrieval in VLR, and this service-user whether contracted VGCS or VBS and other some data relevant with call treatment.

Step S202: if this purpose service-user not signatory any VGCS or VBS, then execution in step S208; Otherwise execution in step S203.

Step S203: if the purpose service-user of this note is not VGCS or VBS speaker service-user or dispatcher, then execution in step S204.

MSC knows in the VLR inquiry whether the purpose service-user of this note is speaker's service-user or the dispatcher of current ongoing VGCS or VBS, if this purpose service-user is not speaker's service-user or the dispatcher of current ongoing VGCS or VBS, then execution in step S204; Otherwise, execution in step S210.

Step S204:MSC obtains signatory VGCS of this purpose service-user or VBS tabulation, and the state of current each VGCS or VBS.

If signatory VGCS of this purpose service-user or VBS, and, be not speaker's service-user or the dispatcher of current ongoing VGCS or VBS, then MSC is further according to this service-user that GCR preserved signatory VGCS or VBS state, obtain signatory VGCS of this purpose service-user or VBS group id and group call region sign, wherein group id and group call region sign constitutes group call reference or the broadcasting reference of unique identification VGCS or VBS together, and the state of current each VGCS or VBS.

Step S205: if the current unactivated state that all is in of VGCS that is contracted or VBS, then execution in step S208; Otherwise, execution in step S206.

If VGCS that this purpose service-user of being preserved among the GCR is signatory or the state of VBS are unactivated state, then execution in step S208; Otherwise, execution in step S206.

Step S206:MSC sends beep-page message to base station controller, the indication base station controller contract at the purpose service-user, the purpose service-user of paging note in the current VGCS that is in state of activation or the VBS zone also.

At this purpose service-user is not under the speaker's service-user of the VGCS that activated or VBS or dispatcher's the condition, if one or more VGCS that this purpose service-user of being preserved among the GCR is signatory or the state of VBS are state of activation, the broadcasting reference that MSC obtains group call reference or the VBS of this VGCS to the GCR inquiry, send the beep-page message that carries this group call reference or broadcasting reference to BSC, the purpose service-user of indication BSC paging note at entrained group call reference or in broadcasting with reference to VGCS that is identified or VBS zone.

That step S207:BSC is contracted at the purpose service-user, and current VGCS that is in state of activation or VBS zone in the purpose service-user of paging note, and send described note according to the response of service-user.

BSC is according to group call reference that carries in the beep-page message or broadcasting reference, paging purpose service-user in " shared channel " channel that cell identified in beep-page message.

If in step S203, retrieving this purpose service-user current in VLR is not speaker's service-user or dispatcher, this purpose service-user may be as hearer's service-user in a certain VGCS or VBS or broadcasting, also may have neither part nor lot among any VGCS or the VBS, under this kind situation, to the shared channel cell value in the beep-page message, and make value sign: the FACCH of VGCS or VBS, promptly BSC group call reference or broadcasting with reference to VGCS that is identified or VBS in this purpose of paging user among the FACCH.

In order to prevent in paging, purpose service-user leaving group-calling or broadcasting, simultaneously, BSC witnesses service-user in the paging channel paging.

Step S208:MSC sends beep-page message to BSC, and the indication base station controller is at the purpose service-user of paging passage paging note.

If not signatory any VGCS or the VBS of this purpose service-user, perhaps, signatory VGCS of this purpose service-user or VBS, but all VGCS or the current unactivated state that is of VBS of being contracted, then MSC sends beep-page message to BSC, to the channel cell value in the beep-page message, make value identification service channel, this Traffic Channel can be thought the Traffic Channel of full rate, can also be the Traffic Channel of half rate, concrete condition is selected to be provided with according to actual business requirement.BSC is at paging channel paging purpose service-user in indication.

The purpose service-user of step S209:BSC paging note on the paging passage, and send described note according to the response of service-user.

Step S210: adopt the supplementary service message transmitting short message.

If speaker's service-user or dispatcher that this purpose service-user is current VGCS or VBS then adopt supplementary service message to this speaker's service-user or dispatcher's transmitting short message.

Below specifically with regard to MSC how according to actual conditions, the structure beep-page message, indication BSC carries out the operation of paging note purpose service-user, makes specific description:

The beep-page message that making for convenience sends to BSC can not be speaker's service-user or the dispatcher of VGCS or VBS at note purpose service-user, and, signatory VGCS of this purpose service-user or VBS, and, that is contracted is professional current under the situation of activated state, indication BSC paging purpose service-user in concrete VGCS or VBS, can work as not signatory VGCS of note purpose service-user or VBS, perhaps, VGCS or VBS though contracted, but that is contracted is professional current when all being in unactivated state, BSC is at paging passage paging note purpose service-user in indication, promptly according to common point-to-point note flow processing, the cell of the beep-page message shown in our his-and-hers watches one: paging information, the expansion of having done makes that MSC can be according to specific circumstances, make BSC to finish different paging operations according to beep-page message, the structure of the paging information cell after the expansion specifically as shown in Table 3:

Table three

In table three, the cell of the 1st byte: source identity, consistent with the effect of the prior art shown in the table one, be used to identify the paging information cell;

The cell of the 2nd byte: Status Flag, the cell that this cell increases newly for the present invention, being used at this note purpose service-user is not under the current VGCS that is in state of activation or VBS speaker service-user or dispatcher's the prerequisite, and whether signatory VGCS or VBS and the current state of service of being contracted all are unactivated states to identify this note purpose service-user.Such as, if in step S202, know not signatory any VGCS or the VBS of this purpose service-user, perhaps, in step S205, though know this purpose service-user contracted VGCS or VBS business, but the current unactivated state that all is in of VGCS that is contracted or VBS, be " 00000000 " with this cell value so, this service-user of paging among VGCS that indication BSC need not in this purpose service-user position district or the VBS, and only need be according to the transmission of common point-to-point note, the paging passage paging purpose service-user in the lane place gets final product; If in step S205, know signatory VGCS of this purpose service-user or VBS, and, this note purpose service-user is not current VGCS or VBS speaker service-user or the dispatcher who is in state of activation, and, have a professional current state of activation that is in of being contracted at least, so, with this cell value be: " 11111111 ", indication BSC paging purpose service-user in VGCS or VBS.What deserves to be explained is, more than to the value of this cell for example, just a kind of scheme of this cell value can adopt other value scheme according to concrete predefine in practice.

The 3rd, 4, the cell of 5 and 6 bytes and later (3+ (n-1) * 3), (4+ (n-1) * 3), the cell of (5+ (n-1) * 3) and (5+ (n-1) * 3) byte is respectively: group call reference or broadcasting are with reference to cell, be used for knowing signatory VGCS of this purpose service-user or VBS as step S205, and, this note purpose service-user is not current VGCS or VBS speaker service-user or the dispatcher who is in state of activation, and, has contracted professional current when being in state of activation at least, carry this current signatory group call reference or broadcasting reference that is in activated state respectively, wherein n is a natural number.Show as table three, preceding 3 bytes of this cell (as the 3rd, 4 and 5 bytes) are used to carry the binary coding of group call reference or broadcasting reference, and the 5th bit of last byte of cell is used for that binary coding that preceding 3 bytes of sign (as the 3rd, 4 and 5 bytes) carry is specially group call reference or for broadcasting reference.The number of this cell is specifically signatory and currently be in the VGCS of state of activation or the number of VBS is determined according to this purpose service-user that is obtained among the step S204, such as, if in step S204, know that signatory also current VGCS or the VBS that is in state of activation of this purpose service-user has only one, to be stored among the GCR so, the group call reference of this VGCS or VBS correspondence or broadcasting is with reference to inserting in the beep-page message, specifically is that the group call reference that constitutes of the 3rd, 4,5 and 6 bytes or broadcasting are with reference to getting final product in the cell.If in step S204, know more than one of signatory and current VGCS that is in state of activation of this purpose service-user or VBS, increase group call reference or broadcasting so with reference to the cell number, make this cell number equal the signatory and current number that is in the VGCS or the VBS of state of activation of other these purpose service-users, and, insert respectively in each cell this VGCS or pairing group call reference of VBS or broadcasting reference.

What deserves to be explained is, if in step S201, know not signatory any VGCS or the VBS of this purpose service-user, perhaps, in step S204, though know this purpose service-user contracted VGCS or VBS business, but the current unactivated state that all is in of VGCS that is contracted or VBS, conspicuous, need not in the paging information cell in beep-page message, carry group call reference or broadcasting with reference to cell.BSC is directly according to the cell of the 2nd byte: the value of Status Flag, know that this purpose service-user is not in the VGCS or VBS of this lane place, therefore directly at this purpose service-user of paging channel paging, and can paging in the VGCS of lane place or VBS.

By on can see, owing to adopted technical scheme of the present invention, for note purpose service-user is not VGCS or VBS speaker service-user or dispatcher, but the situation of signatory VGCS of this purpose service-user or VBS, just think the VGCS that is contracted or VBS is current when having at least a business to be in state of activation, just meeting, and only can be in VGCS that this purpose service-user is contracted or VBS paging purpose service-user, thereby technical solution of the present invention, relative prior art has avoided point-to-point note paging to signatory VGCS of this purpose service-user in this service-user position district or the influence of VBS.

Embodiment 2:

Present embodiment be primarily aimed at MSC can know the purpose service-user whether as hearer's service-user participate in its contract and the situation of current VGCS that is in state of activation or VBS under, use method of the present invention.Figure 3 shows that present embodiment method flow schematic diagram, as shown, the present invention includes following step:

Step S300:MSC receives point-to-point note, resolves and obtains note purpose service-user number.

Whether signatory step S301:MSC inquire about this service-user VGCS or VBS.

More than two steps identical with step S200, step S201 among the embodiment 1.

Step S302: if this purpose service-user not signatory any VGCS or VBS, then execution in step S309; Otherwise execution in step S303.

Step S303: if the purpose service-user of this note is not VGCS or VBS speaker service-user or dispatcher, then execution in step S304; Deny person's execution in step S311.

Step S304:MSC obtains signatory VGCS or VBS tabulation, and the state of current each VGCS or VBS.

Step S305: if the current unactivated state that all is in of VGCS that is contracted or VBS, then execution in step S309; Otherwise, execution in step S306.

Step S306: judge that whether this purpose service-user is the VGCS of the current state that is in activation or hearer's service-user of VBS, if not, execution in step S309 then; Otherwise execution in step S307.

Step S307:MSC sends beep-page message to BSC, the purpose service-user of indication BSC paging note in current VGCS that is just participating in as hearer's service-user of purpose service-user or VBS zone.

The purpose service-user of paging note in current VGCS that is just participating in as hearer's service-user of step S308:BSC purpose service-user or the VBS zone, and send described note according to the response of service-user.

Step S309:MSC sends beep-page message to BSC, and indication BSC is at the purpose service-user of paging passage paging note.

The purpose service-user of step S310:BSC paging note on the paging passage, and send described note according to the response of service-user.

Step S311: adopt the supplementary service message transmitting short message.

Therefore, different is for present embodiment and embodiment 1, the basic step of present embodiment is substantially the same manner as Example 1, different is: in the present embodiment, in step S305, at this purpose service-user under the prerequisite for the speaker's service-user of current VGCS that is in state of activation or VBS or dispatcher, if at least one professional current state of activation that is in of VGCS that this purpose service-user is contracted or VBS, so, MSC further obtains, whether this purpose service-user participates in certain VGCS that is in state of activation or VBS as hearer's service-user, if this purpose service-user is not as hearer's service-user participate any VGCS or VBS, execution in step S310 paging passage paging purpose user, and sends note so; If this purpose service-user has participated in one of them VGCS or VBS (according to the group service characteristic as hearer's service-user, any one service-user can contract a plurality of VGCS or VBS, but at any time, only to participate in its signatory VGCS or VBS), execution in step S307 then, send beep-page message to BSC, the purpose service-user of indication BSC paging note in current VGCS that is just participating in of purpose service-user or VBS zone.

In VGCS or VBS, for speaker's service-user, because taking the special use of group calling or broadcast upstream, speaker's service-user connects, thereby MSC can be known speaker's service-user, and for participating in VGCS or VBS, take hearer's service-user of group calling or broadcast channel jointly, can make MSC know hearer's service-user (hereinafter to be referred as hearer's recognition technology) of current participation VGCS or VBS by following technical scheme:

All hearer's service-users of in MSC covers the lane place all current participation VGCS or VBS, but periodically send the message of the characteristic information that carries unique identification oneself to the MSC of network side, report " I am in group calling or broadcasting " incident, but the characteristic information that wherein is somebody's turn to do unique identification oneself can be the Subscriber Number of this service-user terminal, MSC is according to the Subscriber Number in the received reporting message, can know that this service-user participates in current VGCS or VBS business as hearer's service-user, and store VGCS or the VBS that this service-user number and its are participated in.

Can see by above, owing in VGCS or VBS, adopted technique scheme, MSC can be known the current Subscriber Number that participates in any service-user of certain VGCS or VBS as hearer's service-user, after the MSC Short Message Service Gateway receives point-to-point note, further retrieval is obtained this note purpose service-user and whether has been participated in its signatory VGCS or VBS business as speaker's service-user in step S306, if, then further obtain VGCS or pairing group call reference of VBS or broadcasting reference that this purpose service-user is participated in, and send to BSC and to carry this group call reference, or the beep-page message of broadcasting reference, the purpose service-user of indication BSC this note of paging at this group call reference or in broadcasting with reference to VGCS that is identified or VBS; If in step S306,, know that the purpose service-user of this note is current as any VGCS or the VBS of speaker's service-user participation, then execution in step S309 according to result for retrieval.

Therefore the relative embodiment 1 of present embodiment has more superior technique effect.Make MSC can know the current any service-user that whether participates in VGCS or VBS in real time owing to quoted " hearer's recognition technology " as speaker's service-user, thereby make that the purpose service-user of working as this note is not current the be in VGCS of state of activation or speaker's service-user or the dispatcher of VBS, and under the situation of signatory VGCS or VBS, only paging in the current VGCS that participates in as hearer's service-user of this note purpose service-user in this service-user position district or the VBS zone of BSC, further avoided point-to-point message paging, to the influence of any current VGCS that has neither part nor lot in of this note purpose service-user or VBS.

Therefore, if in VGCS or VBS business, adopted " hearer's recognition technology ", maximum only one of needss of cell that being used in the beep-page message so as shown in Table 3 carried group call reference or broadcasting reference are used to carry the group call reference of current VGCS that participates in as hearer's service-user of this purpose service-user or VBS or broadcast reference.

Embodiment 3:

Be illustrated in figure 4 as the schematic flow sheet of present embodiment method, as shown, this method may further comprise the steps:

Step S400:MSC receives point-to-point note, resolves and obtains note purpose service-user number.

Step S401: if this purpose service-user is not the current VGCS of state of activation or speaker's service-user or the dispatcher of VBS, then the execution in step S402 of being in.

MSC is according to purpose service-user number, and whether the purpose service-user of this note of retrieval is current the be in VGCS of state of activation or speaker's service-user or the dispatcher of VBS in VLR, if not, execution in step S402 then; Otherwise directly adopt the purpose service-user transmitting short message of the mode of supplementary service to note.

Step S402:MSC obtains VGCS or the VBS tabulation that the purpose service-user of this note is contracted, and the current state of VGCS that is contracted or VBS.

Whether MSC is according to purpose service-user number, the purpose service-user present position district sign of this note of retrieval in VLR, and this service-user contracted VGCS or VBS and other some data relevant with call treatment.

If, according to know signatory at least one VGCS of this service-user or VBS at the Query Result of VLR, then VGCS or VBS state that further this purpose service-user of inquiry has been contracted in GCR, and this VGCS or the pairing group call reference of VBS or broadcasting reference.

In the paging information cell of step S403:MSC in beep-page message, increase and to be used to identify this purpose service-user whether signatory VGCS or VBS, and the cell of the current state of VGCS that is contracted or VBS--Status Flag cell.

Step S404: if signatory VGCS of this purpose service-user or VBS, perhaps signatory VGCS or VBS, still the VGCS or the VBS current state of being contracted is unactivated state, then execution in step S405; Otherwise execution in step S406.

The cell of step S405:MSC to increasing newly among the step S403--Status Flag cell value, and execution in step S407.

To the cell that increases newly among the step S403--the Status Flag cell carries out value, make this cell value indicate: not signatory any VGCS or the VBS of this purpose service-user, though perhaps signatory VGCS or VBS, but VGCS that is contracted or VBS current state are unactivated state, after making that BSC receives group calling message, according to this cell value, know: not signatory any VGCS or the VBS of this purpose service-user, though perhaps signatory VGCS or VBS, but VGCS that is contracted or VBS current state are unactivated state, and only at the purpose service-user of paging passage paging note.

Step S406:MSC is to the cell among the step S403--Status Flag cell value, and in beep-page message, carry signatory and current VGCS or pairing group call reference of VBS or the broadcasting reference that is in state of activation of this purpose service-user.

The Status Flag cell is carried out value, make this cell value indicate: signatory at least one VGCS of this purpose service-user or VBS, and VGCS that at least one is contracted or VBS current state are state of activation, and this purpose service-user is not the VGCS that activated or speaker's service-user or the dispatcher of VBS, after making that BSC receives group calling message, according to this cell value, know: signatory at least one VGCS of this purpose service-user or VBS, and VGCS that at least one is contracted or VBS current state are state of activation, and this purpose service-user is not the VGCS that activated or speaker's service-user or the dispatcher of VBS.

Further, in beep-page message, be filled in the group call reference or the broadcasting reference of being obtained among the step S402.If at this purpose service-user under the prerequisite for the speaker's service-user of current VGCS that is in activated state or VBS or dispatcher, this purpose service-user is signatory, and more than one of the current VGCS that is in state of activation or VBS, then insert pairing group call reference of this VGCS or VBS or broadcasting reference respectively.

Step S407:MSC sends beep-page message to BSC.

MSC is sent to BSC with the beep-page message that is obtained, the purpose service-user of indication BSC paging note.

Therefore, if not signatory any VGCS of the purpose service-user of this note or VBS, perhaps, though signatory VGCS or VBS, but the current equal un-activation of VGCS that is contracted or VBS, the paging information cell structure of the beep-page message that is sent in step S406 is as shown in Table 4 so:

Table four

If signatory VGCS of this short message service user or VBS, and this purpose service-user is not current the be in VGCS of activated state or speaker's service-user or the dispatcher of VBS, and the current state of activation that is in of VGCS that at least one is contracted or VBS, the paging information cell structure of the beep-page message that is sent in step S406 as shown in Table 5 so.

In the table five the 3rd, 4,5 and 6 bytes are used for carrying this purpose service-user that step S402 obtained contracts, and current VGCS or pairing group call reference of VBS or the broadcasting reference that is in state of activation.As shown in Table 5, wherein this group call reference or broadcasting are that the type of service sign (as the 5th bit of the 6th byte of table) of group call reference or broadcasting reference constitutes with reference to the binary coding that is used for identifying this group call reference or broadcasting reference by the binary coding (as the 3rd, 4 and 5 bytes in the table) of the group call reference of three bytes or broadcasting reference and bit.

Table five

After the 3rd byte shown in the table five, comprise that the 3rd byte all is used for carrying signatory and current VGCS or pairing group call reference of VBS or the broadcasting reference that is in state of activation of this purpose service-user that step S401 is obtained.The number of entrained group call reference or broadcasting reference is decided according to signatory also current VGCS or the VBS number that is in state of activation of this purpose service-user that is obtained among the step S402.

As seen from the above, according to the situation difference of signatory VGCS of this purpose service-user or VBS, MSC differs also different to the length of the beep-page message paging information cell that BSC sent.Therefore, this group calling message can adopt type lengths values coding (Type Length Value is called for short TLV) structure to encode.

As from the foregoing, owing to adopted above coding method, make that beep-page message can be according to the situation of signatory VGCS of this service-user or VBS, indication BSC carries out corresponding note purpose service-user paging operation, as signatory VGCS of this purpose service-user or VBS, and, this purpose service-user is not current the be in VGCS of activated state or speaker's service-user or the dispatcher of VBS, and the current un-activation of VGCS that at least one is contracted or VBS, BSC is according to the Status Flag that carries in the beep-page message, in beep-page message entrained group call reference or broadcasting the reference VGCS or VBS zone that are identified, paging purpose service-user, avoided point-to-point note paging in this service-user position district with irrelevant VGCS of this purpose service-user or the influence of VBS.

Embodiment 4:

Figure 5 shows that the schematic flow sheet of present embodiment method, as shown, this method may further comprise the steps:

Step S500:MSC receives point-to-point note, resolves and obtains note purpose service-user number.

Step S501: if this purpose service-user is not the current VGCS of state of activation or speaker's service-user or the dispatcher of VBS, then the execution in step S502 of being in.

More than two steps respectively with step S400, the step S401 of 3 kinds of embodiment in like manner.

Step S502:MSC obtains VGCS or the VBS tabulation that the purpose service-user of this note is contracted, and the current state of VGCS that is contracted or VBS, and know that whether this service-user participates in being in the VGCS or the VBS of state of activation as hearer's service-user, and the group call reference of VGCS that is participated in or VBS correspondence or broadcasting reference.

In VGCS or VBS, for participating in VGCS or VBS, take hearer's service-user of group calling or broadcast channel jointly, can make MSC know hearer's service-user (hereinafter to be referred as hearer's recognition technology) of current participation VGCS or VBS by following technical scheme:

All hearer's service-users of in MSC covers the lane place all current participation VGCS or VBS, but periodically send the message of the characteristic information that carries unique identification oneself to the MSC of network side, report " I am in group calling or broadcasting " incident, but the characteristic information that wherein is somebody's turn to do unique identification oneself can be the Subscriber Number of this service-user terminal, MSC is according to the Subscriber Number in the received reporting message, can know VGCS or VBS business that this service-user is participating in as hearer's service-user, and store VGCS or the VBS that this service-user number and its are participated in.

After MSC receives point-to-point note from Short Message Service Gateway, the purpose service-user number of this point-to-point note is obtained in parsing, and according to purpose service-user number, the purpose service-user present position district sign of this note of retrieval in VLR, and this service-user whether contracted VGCS or VBS and other some data relevant with call treatment.

If, according to know signatory at least one VGCS of this service-user or VBS at the Query Result of VLR, VGCS or the VBS that further this purpose service-user of inquiry institute participates in as hearer's service-user in GCR then, and VGCS that this participated in or the pairing group call reference of VBS or broadcast reference.

In the paging information cell of step S503:MSC in beep-page message, increase and to be used to identify current cell--the Status Flag cell that whether participates in VGCS or VBS of this purpose service-user as hearer's service-user.

Step S504: if this purpose service-user does not participate in any VGCS or VBS, then execution in step S505 as hearer's service-user; Otherwise execution in step S506.

The cell of step S505:MSC to increasing newly among the step S503--Status Flag cell value, and execution in step S507.

To the cell that increases newly among the step S503--the Status Flag cell carries out value, make this cell value indicate: not signatory any VGCS or the VBS of this purpose service-user, though perhaps signatory VGCS or VBS, but VGCS that is contracted or VBS current state are unactivated state, perhaps, this purpose service-user does not participate in any its signatory and that be in state of activation VGCS or VBS as hearer's service-user, after making that BSC receives group calling message, according to this cell value, know: this purpose service-user is not at the group calling passage of current any VGCS that has activated or the broadcast channel of VBS.

Step S506:MSC is to the cell among the step S503--Status Flag cell value, and in beep-page message, carry this purpose service-user the VGCS or pairing group call reference of VBS or the broadcasting reference that participate in as hearer's service-user.

The Status Flag cell is carried out value, make this cell value indicate: this purpose service-user participates in VGCS or VBS as hearer's service-user, after making that BSC receives group calling message, according to this cell value, know: this purpose service-user is in VGCS or VBS.
