Description
Technical field
The invention belongs to the trunking communication field, relate in particular to the method that user user outside group in the group calling group in the trunked communication system sends point-to-point short message.
Background technology
Wireless trunking communication system, be called for short group system, be a kind of less expensive of growing up in recent years, command dispatching and communication system more flexibly, be widely used in units such as government bodies, energy traffic, airport harbour, industrial and mining enterprises, fire-fighting police, water conservancy and military affairs, to satisfy the needs of constituent parts intercommunication.
In the present group system, each group comprises a group id ID and group call region, and wherein group call region is defined as the gang sub-district.But these information all are some when opening an account at HLR (Home LocationRegister, attaching position register) and SIM (Subscriber Identity Module, subscriber identification module) fix information of storage in the card, and be unrealized to group calling user's mobile management.
Fig. 1 shows the structure of trunked communication system core net, there is user profile among the HLR, comprise that this user IMSI (International Mobile Subscriber Identity, international mobile subscriber identity), affiliated group ID tabulate (user can belong to 50 groups at most).GMSC (Gateway MobileSwitch Center, gateway mobile switch) links to each other with external network, and GMSC also links to each other with anchor MSC (AnchorMSC).Anchor MSC is in charge of and safeguards a specific VGCS (Voice Group CallService, speech group calls in several business).
Relay MSC (Relay MSC) is when group call region jumps a plurality of MSC, all MSC except that anchor MSC.It between anchor MSC and the relay MSC the tree-shaped relation of one-to-many.VLR (VisitedLocation Register, Visited Location Registor) has the ID tabulation of organizing under user IMSI, this user.When the user roamed, these information copied from HLR and come.
Comprised group ID and group call region among the GCR (Group Call Register, group calls in several register), group call region lumps together with group ID and is called group call reference.Wherein with among the continuous GCR of anchor MSC the dispatcher tabulation relevant, relay MSC tabulation, the directly actuated cell list of anchor MSC have been comprised with this group call reference.The GCR that links to each other with relay MSC has then comprised the anchor MSC address relevant with this group call reference, the cell list that this relay MSC is controlled.
Receive that anchor MSC inquired about this group attribute to the GCR that is connected when request was initiated in group calling.Obtain the cell list under dispatcher's tabulation, relay MSC tabulation and this MSC control.And then call scheduling person, group-calling channel is set up in calling relay MSC and the sub-district under this MSC control, there is group calling to initiate by user in NCH (Notification Channel, the notification channel) group of notifications of each sub-district, and indicates its group-calling channel so that the user monitors in the group.
After relay MSC is received the group calling request of anchor MSC,, in these sub-districts, set up group-calling channel, have group calling to initiate by user in the NCH group of notifications, and indicate its group-calling channel so that the user monitors in the group to the GCR inquiry cell list that is connected.
When initiating a group calling, one group of user in the specific region can join group calling simultaneously and monitor the talker.Can only there be a talker the same time, and after the talker had said, other user can both become the talker by pressing PTT key (Push to talk, press-and-talk).In communication process, Any user can own decision be left midway or join in the group calling midway, and the user who enters group call region can have notice and join midway and lead in the calling.
The speaker can take the uplink group cal channel, monitors descending group-calling channel simultaneously; Network also can distribute an independently up-downgoing dedicated channel separately for the talker.But the hearer can only monitor descending group-calling channel.
Short message is carrier transmission Word message with the No.7 nation-wide Network.The size of the information content is limited in about 70 words (140 bytes).Short message is mainly with portable terminal end-to-end transmission and reception, and the transmission between portable terminal and the Internet and be received as the master.
Short message transmits by radio control channel, finishes storage and preceding rotating function through short message breath service center, and the amount of information of each short message breath is restricted to 140 bytes.The information (plain text) that sends out from transmit leg is stored in short message service center, and then is forwarded to the purpose user terminal.Even because shutdown or other reasons and when can not receive information immediately, system still can preserve information and resend in suitable after a while with regard to meaning when receiving side terminal for this.
In the prior art, be in user among the group calling when network sends SMS message, corresponding processing procedure is as follows:
1, the user who is in the group calling sends SMS message if desired, manually withdraws from this call service group by the user;
2, this user edits and sends SMS message to SC (Service Center, service center);
3, be sent completely when short message,, then manually initiate to add the request of group calling once more, insert call service group again by the user if this user needs.
As from the foregoing, in the prior art, when being in user in the group calling and sending SMS message, the process of the access group calling of need experience from group, to withdraw from, send SMS message, the user initiating again.If the user is the speaker of group calling, this user need at first discharge the group call uplink link or dedicated uplink channels enters group receive mode, and button withdraws from group calling then.Because this user is possible be to have the user that group calling discharges power, the user who has group calling release authority who for example defines among group calling promoter, the GCR, may there be user's the error such as the error of button or menu selection, selected to discharge the option of group calling, cause the complete d/d situation of this group-calling service, have very big group-calling service potential safety hazard.If the user is the hearer, the user will experience and manually withdraw from the group calling and the manual process of access group calling, and this will cause the user will be longer to the time of getting back to call service group from withdrawing from call service group, and promptness is relatively poor.
