By the invention, the group sending short messages can be sent out in case of not establishing the group calling.
Description
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of implementation method of grouped transmitting SMS.
Background technology
Wireless trunking communication system, hereinafter to be referred as 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 trunked communication system, each group comprises a group id (ID) and group call region, and wherein group call region is defined as the gang sub-district, and group call region lumps together with group ID and is called group call reference.These information all be some when opening an account in attaching position register (HLR) and User Identity module (SIM) card the fix information of storage, and be unrealized to group calling user's mobile management.
The group system core network architecture is as shown in Figure 1:
There is user profile in the attaching position register (HLR), comprises this user's international mobile subscriber identification code (IMSI), affiliated group ID tabulation (user can belong to 50 groups at most);
(Gate Mobile Switching Centre's GMSC (gateway mobile switching center) GMSC), links to each other with external network, and also (Anchor MSC's GMSC A-MSC) links to each other, and is in charge of and safeguards a specific group-calling service (VGCS) with anchor mobile switching centre;
Relay MSC (R-MSC) is meant when group call region jumps a plurality of MSC, all MSC except that A-MSC.It between A-MSC and the R-MSC the tree-shaped relation of one-to-many;
(Visitor Location Register VLR) has the ID tabulation of organizing under user IMSI, this user to Visited Location Registor.When the user roamed, these information copied from HLR and come;
Comprised group call reference (group call region and group ID) in the Group Call Register (GCR), wherein with among the continuous GCR of A-MSC comprised the dispatcher tabulation relevant, R-MSC tabulation with this group call reference, and the directly actuated cell list of A-MSC; The GCR that links to each other with R-MSC has then comprised the cell list that the A-MSC address relevant with this group call reference and this R-MSC are controlled.
The group-calling process of group system is:
When A-MSC receives that request is initiated in group calling, A-MSC inquires about this group attribute to the GCR that is connected, obtain dispatcher's tabulation, R-MSC tabulation, and the cell list under this A-MSC control, and then call scheduling person, call out R-MSC, and for setting up group-calling channel in the sub-district under this A-MSC control, A-MSC has group calling to initiate by user in notification channel (NCH) group of notifications of each sub-district, and indicates its group-calling channel parameter so that the user monitors in the group;
After R-MSC receives the group calling request of A-MSC, to the GCR inquiry cell list that is connected, set up group-calling channel in these sub-districts, R-MSC has group calling to initiate by user in the NCH group of notifications of each sub-district, and indicates its group-calling channel parameter so that the user monitors in the group.
When A-MSC initiated 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 be by becoming the talker by PTT (Push to talk) key.In communication process, the Any user in the group 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 in the group calls in several midway.
The talker can take the uplink group cal channel, monitors descending group-calling channel simultaneously; Network also can distribute an independently up-downgoing dedicated channel for the talker is independent, but the hearer can only the descending group-calling channel of intelligent surveillance.
Present radio communication short message realization technology comprises two kinds of situations: point-to-point and point-to-multipoint, and the former receives and dispatches short message and has only a user respectively, and the latter can realize a short message is issued all users of specific region.
It is the mobile subscriber that point-to-point short message has a side at least, can realize the point-to-point message transmission between the user.The transmission of short message is by short message service center (SC) transfer.Short message initiator's content of short message at first is sent to SC, and SC is responsible for the transmission and the preservation of short message.SC is the node that does not belong to Public Land Mobile Nerwork (PLMN), and the user who initiates short message can be that the mobile subscriber also can the Internet (Internet) user.The process that SC sends to the mobile subscriber with short message comprises as shown in Figure 2:
SC at first sends to short message SMS-GMSC (short messaging gateway), the destination address inquiry HLR that SMS-GMSC carries according to short message, obtain mobile subscriber's address, roaming place (being the MSC address at the present place of user), SMS-GMSC mails to above-mentioned address with short message then.After MSC received short message, inquiry VLR obtained user position information, and at the lane place at user place calling user, after user's response, MSC by and user terminal between the slow associated control channel (SDCCH) set up short message is sent to the user.The user successfully receives back feedback acknowledgment message, and local then MSC can feed back to SC with confirmation by SMS-GMSC, and SC deletes the short message of preserving after receiving the message that the user successfully receives.Above-mentioned any step failure, SC can not delete short message.HLR is responsible for following the tracks of the transmission of short message, the user unreachable or in be filled with etc. under the situation, HLR preserves the SC address for short message, when the user can reach again or memory headroom is arranged, HLR notice SC sent SMS message to the user.
The short message process of transmitting of point-to-multipoint is different with above-mentioned point-to-point mode, as shown in Figure 3:
The user at first sends to short message CBC (CBC), and that send the point-to-multipoint short message here generally is not the mobile subscriber.The point-to-multipoint short message carries broadcast cell tabulation, type of message, starting and ending time, plays information such as frequency and use channel.CBC selects base station controller (BSC) to send SMS message according to cell list, and BSC is according to above-mentioned parameter broadcast SMS in the sub-district of regulation.Each BSC can only link to each other with a CBC.(Cell BroadcastChannel CBCH) goes up broadcasting to short message, and the user in all these sub-districts can arrive this channel and receive short message, and the user also can select not receive the wherein short message of some type certainly at the CBCH of BTS.
In the prior art, wish to realize group transmittings short message in the cluster, group transmittings short message belongs to the situation of point-to-multipoint, is to issue certain customers certain zone in but not whole user but difference is group transmittings short message.If group calling is at present set up, the short message process of transmitting is that SC sends to SMS-GMSC with short message so, it is grouped transmitting SMS that SMS-GMSC analyzes this short message according to the destination address of short message, SMS-GMSC inquiry HLR obtains the A-MSC address of group transmittings short message correspondence, then short message is issued this A-MSC, A-MSC is responsible for short message is handed down to all interior users of group at the descending SACCH of group calling (SlowAssociated Control Channel, slow associated control channel) channel.
After SMS-GMSC sent to A-MSC with short message under the situation that group calling does not have to set up, A-MSC returned group calling and does not set up the tabulation of all users in sign and the group and give SMS-GMSC, and SMS-GMSC sends to each user with short message according to point-to-point mode.
In the prior art, bigger to user's short-message sending time delay in all groups according to point-to-point mode under the situation that does not have to set up in group calling, if the user more for a long time in while sub-district, waste of radio resources is bigger, and may cause congested.

Embodiment
Group transmittings short message is a prior art from the process that message sender arrives SC, does not explain at this, and the present invention program only solves the process of from SC to user (MS).
Referring to Fig. 4, be the realization flow schematic diagram of group transmittings short message of the present invention, idiographic flow comprises:
Step 1:SC sends to SMS-GMSC with short message, and carries the subscriber phone number (MSISDN) of purpose group; This MSISDN is made up of with reference to (group ID and group call region) cluster group prefix and group, and this cluster group prefix shows that this is a group transmittings short message;
After step 2:SMS-GMSC receives group transmittings short message, be identified as group transmittings short message according to the Mobile Subscriber International ISDN Number prefix, then inquire about to the internal database (not identifying among the figure) of HLR or SMS-GMSC, obtain the address of corresponding A-MSC, this A-MSC address is the user of current roaming way address in the group;
Step 3:SMS-GMSC sends to this A-MSC with short message;
After step 4:A-MSC receives short message, inquire about the GCR that is attached thereto with corresponding group call reference, if group calling sets up, then A-MSC is according to the process of transmitting of group calling message in the prior art, and group calling message is sent to all users in the group on the descending SACCH channel of group calling; GCR also returns the relevant dispatching desk tabulation of this group call reference to SMS-GMSC, according to point-to-point mode short message is sent to all users in this dispatching desk tabulation by SMS-GMSC;
If behind the inquiry GCR, the discovery group calling is not set up, and then GCR returns group calling to A-MSC and do not set up sign, the directly actuated group call cell tabulation of A-MSC and R-MSC tabulation; After A-MSC receives that sign is not set up in group calling, send the group transmittings short message request of carrying group transmittings short message and arrive the affiliated BSC of directly actuated group call cell, with the R-MSC that links to each other with this A-MSC; After this R-MSC received the group transmittings short message request, the GCR that inquiry connects obtain corresponding group call cell tabulation, and the BSC under whole group call cells sent the group transmittings short message request of carrying group transmittings short message; This group transmittings short message request that sends to BSC is also carried group call reference, is sent number of times, the time interval, initiation user profile and version number information, and the group call cell list information that this BSC administered;
After BSC receives group transmittings short message, for this group transmittings short message distributes wireless channel at each group call cell, this channel parameter information of broadcast transmission in the sub-district, and on this channel, send group transmittings short message; User terminal receives group call reference and oneself signatory group identical group transmittings short message from this channel;
Step 5: in the above-mentioned steps 4, A-MSC to the BSC under the group call cell of its control with after the R-MSC that links to each other with this A-MSC sends short message, no matter success or not all will be returned acknowledge message to SMS-GMSC, and carry the tabulation of all dispatching desks in this group simultaneously; After SMS-GMSC receives the tabulation of this dispatching desk, group transmittings short message is sent to all users in this dispatching desk tabulation according to point-to-point mode;
Step 6:SMS-GMSC according to A-MSC to its affirmation message of returning, to the current state of HLR report short message: if SMS-GMSC receives the send SMS message affirmation message of success of A-MSC, then send successfully to this this short message of HLR report; If SMS-MSC receives the affirmation message that A-MSC sends SMS message and fails, then report that to HLR this short message sends failure, notice HLR preserves the SC address of this group transmittings short message correspondence;
Step 7:SMS-GMSC receives A-MSC after the affirmation message that it returns, and transmits to SC and gives this acknowledge message: if SC receives that short message sends successful acknowledge message, and this group transmittings short message deletion that then will keep; If SC receives short message and sends the affirmation message of failure that it is not deleted then to preserve this group transmittings short message.
In the above-mentioned steps 6, when group transmittings short message sent failure, HLC preserved the SC address of this group transmittings short message correspondence, and periodically required SC to resend this short message, up to certain number of times post command SC this short message was deleted.
In the above-mentioned steps 4, after described BSC receives group transmittings short message, can there be 3 kinds of wireless channels mode that issues that group transmittings short message is sent to the group user: to use CBCH channel, notification channel (Notify Channel, NCH) channel or newly-built multicast channel (Group Broadcast Channel, GBCH), short message is sent to the group user, be illustrated respectively adopting three kinds of channels to send SMS message below.
Mode one: send SMS message by the CBCH channel.
The process that sends SMS message by the CBCH channel is:
1, the BTS of all sub-districts of BSC in tabulation sends the request of group calling short message, carry group transmittings short message and group call reference, go back other information of this group transmittings short message of portability, as initiating user profile and version number information, and necessary transmission condition, as sending the number of times and the time interval;
2, after BTS received this group transmittings short message request, on the CBCH of this sub-district channel, the time interval according to the rules and transmission number of times sent SMS message, and carry group call reference, go back the initiation user profile and the version number information of portability group transmittings short message;
3, all user terminals of this sub-district are monitored CBCH channels, when short message arrives, if the group call reference that short message carries is identical with oneself signatory group, then receive this short message; If user terminal has received the group transmittings short message of identical initiation user and version number, then no longer repeat to receive simultaneously.
Mode two: send SMS message by the NCH channel
The NCH channel is existing notification channel, and the parameter configuration of NCH channel is broadcasted on the BCCH channel, and the mobile subscriber of all starts can be by the configuration parameter of the broadcast reception NCH channel on the BCCH channel.The process that sends SMS message by the NCH channel is:
1, the BTS of all sub-districts of BSC in tabulation sends the request of group calling short message, carry group transmittings short message and group call reference, go back other information of this group transmittings short message of portability, as initiating user profile and version number information, and necessary transmission condition, as sending the number of times and the time interval;
2, after BTS received this group transmittings short message request, on the NCH of this sub-district channel, the time interval according to the rules and transmission number of times sent SMS message, and carry group call reference, go back the initiation user profile and the version number information of portability group transmittings short message;
3, all user terminals of this sub-district are monitored NCH channels, when short message arrives, if the group call reference that short message carries is identical with oneself signatory group, then receive this short message; If user terminal has received the group transmittings short message of identical initiation user and version number, then no longer repeat to receive simultaneously.
Mode three: send SMS message by the GBCH channel
GBCH is exclusively used in signalling of bouquet group short message for the newly-increased system channel of the present invention, uses identical physical channel with SDCCH.The GBCH channel is in deactivated state under the situation that does not have short message to send, when short message sent, BTS can activate this channel.The channel parameter of GBCH is broadcasted on the BCCH channel, and the user of all starts can know the configuration parameter of GBCH by the broadcast on the BCCH channel.The process that sends SMS message by the GBCH channel is:
1, after BSC receives group transmittings short message, at first the BTS of all sub-districts in the tabulation that it carries sends the GBCH channel and activates request, the BTS of all sub-districts in tabulation sends the request of group calling short message then, carry group transmittings short message and group call reference, other information of this group transmittings short message of portability also, as initiate user profile and version number information, and necessary transmission condition, as sending the number of times and the time interval;
2, BTS receives the GBCH channel that activates respective cell after the GBCH channel request, after this group transmittings short message request of reception, use the NCH channel to send the GBCH notification message, carry combined reference, then on the GBCH channel according to the rules the time interval and send number of times and send SMS message, go back this group transmittings short message of portability group call reference, initiate user profile and version number information;
3, user terminal is after receiving the notification message of NCH, if the group call reference that notification message carries is identical with oneself signatory group, then receives the short message that sends on the GBCH channel; If user terminal has received the group transmittings short message of identical initiation user and version number, then no longer repeat to receive simultaneously.
4, BTS at first stops the notification message of NCH channel after distributing to the short message of stipulated number, deactivates the GBCH channel then automatically.
Describe as can be known by above flow process, when group calling was not set up, the BSC of MSC (comprising A-MSC and R-MSC) under the group call cell of this group calling message sent this group calling short message, and carried the tabulation of all group call cells that this BSC administers; BSC is this group transmittings short message allocated channel for each sub-district in the tabulation, and short message is sent to BTS; BTS sends SMS message on this channel; User terminal is monitored this channel, receives group call reference and the identical short message of self contracted user.And the invention provides and use existing CBCH channel, or existing NCH channel, or use the mode of newly-built GBCH channel to send short messages to the group user.Because above-mentioned channel is shared for all users, promptly group transmittings short message sends for all group users at above-mentioned channel, therefore can realize sending fast group transmittings short message, has improved resource utilization effectively.In addition, multiple channel send mode provided by the invention, the flexibility that has improved system.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
