Description
Technical field
The present invention relates to wireless communication field, relate in particular to the group transmittings short message implementation method in a kind of wireless trunking communication system short message service.
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);
GMSC (gateway mobile switching center) (Gate Mobile Switching Centre, GMSC), link to each other with external network, GMSC also with (the Anchor MSC of anchor mobile switching centre, A-MSC) link to each other, be in charge of and safeguard a specific voice group call service (Voice Group Call Service, VGCS);
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.
Note is to be carrier with the No.7 nation-wide Network, the transmission Word message.The general size of the information content is limited in about 70 words (140 bytes).Note is mainly with the transmission and the reception of mobile phone end to end system, and the transmission between mobile phone and the Internet and be received as the master.
The mobile network generally includes voice channel and control channel two large divisions.Though note is the same with speech transmissions and fax, is all the main value-added telecom services that GSM digital mobile cellular telecommunication network provides, note does not take voice channel, has so not only guaranteed the quick of transmission, and has greatly reduced the communication cost.
In the mobile communications network, note is transmitted by radio control channel, finishes storage and preceding rotating function through Short Message Service Center.The information (plain text) that sends out from transmit leg is stored in short message service center (SMS), and then is forwarded to the purpose user terminal.Like this, though receiving side terminal because shutdown or other reasons and when can not receive short message immediately, system still can save short message and resend in suitable after a while.
Short message is realized mainly being present in by the outer user of group user in group and is sent in the group system of the prior art.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 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.
In the group system, short message process of transmitting specific as follows:
1, SC sends to (the Short MessageService-Gateway Mobile Switching Centre of short messaging gateway mobile switching centre with short message, SMS-GMSC), the group call reference that comprises short message reception group in the short message, SC do not keep this short message;
2, SMS-GMSC inquires about HLR or the SMS-GMSC internal database that is attached thereto according to group call reference, obtains the address information of corresponding A-MSC, and short message is sent to this A-MSC;
3, after A-MSC receives short message, inquire about corresponding group calling parameter to corresponding GCR;
4, whether GCR sets up current group calling group and the dispatcher of this group calling group tabulation returns to A-MSC;
5, under the situation that group calling is set up, A-MSC receives the short message that SMS-GMSC sends, and returns the message that the dispatcher tabulates and group calling has been set up to SMS-GMSC, changes step 6 over to, carries out the process of transmitting of short message; Under the situation that does not have to set up in group calling, A-MSC does not receive the short message that SMS-GMSC sends, and return the dispatcher to SMS-GMSC and tabulate and the unfounded message of group calling, the mode that SMS-GMSC sends according to point-to-point standard short message sends short messages to the user in dispatcher's tabulation, and changes step 7 over to;
6, under the situation that group calling has been set up, SMS-GMSC obtains routing iinformation by group call reference, short message is dealt into the MSC (A-MSC or R-MSC) at each user place in the group calling, by corresponding M SC (A-MSC or R-MSC) short message is sent to the user again, after the user receives short message, can not return and receive report.That is, SMS-MSC only sends short message one time, just short message has been deleted then.Said process is that point-to-multipoint sends SMS message, and a short message is issued all users of specific region;
7, under the situation that group calling does not have to set up, SMS-GMSC inquires about external data base, resolve route messages respectively at each user, then short message is sent to the MSC (not having the differentiation of A-MSC, R-MSC) at user place respectively, duplicate many parts of short messages according to number of users, short message is sent to the user by MSC, after the user receives short message, to send and transmit report as acknowledge message, and give SMS-GMSC through MSC, SMS-GMSC will delete this short message.Said process is point-to-point sending SMS message, the transmitting-receiving short message all have only a user respectively.
In the short message transmission flow of existing group system, the short message that the sender of short message will have group call reference sends to SC, SC directly sends to SMS-GMSC with this short message, preserve this short message by SMS-GMSC, inquire about whether group calling foundation and dispatcher's tabulation then to GCR, under the unfounded situation of group calling, follow-up point-to-point short message sends fully to be judged and operation by SMS-GMSC, does not return to any acknowledge message of SC.SC does not do to preserve to short message when sending the group calling short message and handles just as a Signalling Transfer Point as can be seen.
Therefore, when unreachable or user terminal capacity overflowed as the user, the MSC at user place sent error reporting to SC, but because SC does not save short message, HLR will be left in the basket through the error reporting that SMS-GMSC sends to SC, that is to say that short message will be no longer retransmitted.Concerning the user, short message has only sent once, if because the user is unreachable or the user terminal capacity overflows, the user will can not receive this short message again.This situation has greatly been destroyed the validity and the fail safe of short message service.
Summary of the invention
The invention provides the implementation method of group transmittings short message, in order to solve the problem of group transmittings short message transmission poor reliability in the prior art.
One of group transmittings short message implementation method provided by the invention is applied to the situation that the wireless trunking communication system group calling has been set up, comprising:
The SC of short message service center receives described short message and is kept at this locality;

Embodiment
Respectively at group calling foundation and the unfounded situation of group calling, the inventive method is elaborated below.
Referring to Fig. 2, short message sends successful flow chart under the situation for group calling of the present invention is set up, and SC is kept at this locality with this short message after receiving the group transmittings short message of transmit leg, carry out following steps:
The short message that step 1, SC will have group call reference sends to SMS-GMSC;
Step 2, SMS-GMSC according to short message with group call reference inquiry external data base or HLR, find the A-MSC address of this VGCS business; The short message that will have group call reference sends to corresponding A-MSC;
Current attribute and dispatcher's tabulation of this group calling of inquiry in the corresponding GCR of step 3, A-MSC;
Step 4, GCR return to dispatcher's tabulation of state information, R-MSC tabulation and this group calling that this group calling of A-MSC " sets up ";
Step 5, A-MSC receive the short message that SMS-GMSC sends, and short message is sent to all R-MSC at group calling place, and notice R-MSC sends SMS message;
Step 6, A-MSC successfully send to SMS-GMSC report short message after successfully short message being sent to R-MSC, carry dispatcher's tabulation of this group calling;
Step 7, SMS-GMSC successfully send to SC report short message, and SC is with the short message deletion of preserving;
Step 8, A-MSC send to this group calling user under this A-MSC with short message;
Step 9, R-MSC send to this group calling user under this R-MSC with short message.
In the above-mentioned process step 6, after SMS-GMSC receives that the short message that carries dispatcher tabulation sends successfully report, short message is sent to dispatcher all users in tabulating according to point-to-point mode.
In the short message transmission flow after group calling is set up, short message is broadcasted on the group calling down channel, and the user receives short message, does not need to confirm.
Referring to Fig. 3, short message sends the flow chart of failing under the situation for group calling of the present invention is set up, and SC is kept at this locality with this short message after receiving the short message of transmit leg, carry out following steps:
Step 1-3, with the step 1-3 in Fig. 2 flow process;
Step 4, if A-MSC is after sending the group calling status poll to GCR, do not receive response message, then to the SMS-GMSC transmission failure reporting that sends SMS message, the failure cause that carries in the report is whether to set up other irrelevant network failure with group calling, as link failure etc.;
Step 5, SMS-GMSC transmit short message to SC and send failure reporting, and SC sends out the short message transmission flow of setting up under the situation according to group again and sends this short message.
If send failure once more, then repeat above-mentioned steps 1-5; If send successfully, its flow process is with the step 1-9 in Fig. 2 flow process.Reach preset threshold when retransmitting the short message number of times, perhaps the short message of preserving among the SC reaches the short message lifetime, then finishes transmission flow, and with this short message deletion.
Referring to Fig. 4, short message sends successful flow chart under the situation for group calling of the present invention is not set up, and SC is kept at this locality with this short message after receiving the group transmittings short message of transmit leg, carry out following steps:
The short message that step 1, SC will have group call reference sends to SMS-GMSC;
Step 2, SMS-GMSC according to short message with group call reference inquiry external data base or HLR, find the A-MSC address of this VGCS business; The short message that will have group call reference sends to corresponding A-MSC;
Current attribute and dispatcher's tabulation of this group calling of inquiry in the corresponding GCR of step 3, A-MSC;
Step 4, GCR return to dispatcher's tabulation of state information, R-MSC tabulation and this group calling of A-MSC this " group calling is not set up as yet ";
After step 5, A-MSC receive the state information of this " group calling is not set up as yet ", do not receive the short message that SMS-GMSC sends, and send the report of group calling short message failure to SMS-GMSC, carrying failure cause is that identification information is not set up in group calling as yet, and carries dispatcher's tabulation of this group calling;
Step 6, SMS-GMSC send the report that the group calling short message is failed to SC, and the reason of failure is that group calling is set up as yet;
Step 7, takes place simultaneously with step 6, SMS-GMSC inquiry external data base or HLR obtain user profile, owing to will initiate short message service respectively individually at each user, so duplicate this short message for each user.SMS-GMSC comprises MSC or Serving GPRS Support Node (Serving GPRS Support Node, SGSN) address that the user is affiliated to the necessary information that HLR inquires about and obtains sending SMS message;
Step 8, SMS-GMSC send to short message the MSC or the SGSN at the current place of user;
After step 9, MSC receive short message, to Visited Location Registor (Visitor Location Register, VLR) inquiring user receives some authentication informations of short message, guarantees that the user can legal reception short message, SGSN does not need this operation;
Step 10, for validated user, MSC or SGSN send to the user with short message;
After step 11, user terminal successfully receive short message, return short message to affiliated MSC or SGSN and successfully send report;
Step 12, MSC or SGSN send successfully report to the short message that SMS-GMSC returns this user;
Step 13, SMS-GMSC send this user's short message status report to HLR;
After step 14, SMS-GMSC received all users' successful transmission report, sending SMS message to SC sent successfully report, and SC deletes this short message.
In the above-mentioned process step 5, after SMS-GMSC receives that the dispatcher tabulates, short message is sent to all users in the dispatcher tabulation according to point-to-point mode.
Referring to Fig. 5, short message sends the flow chart of failing under the situation for group calling of the present invention is not set up, and SC is kept at this locality with this short message after receiving the group transmittings short message of transmit leg, carry out following steps:
Step 1-10, with the step 1-10 in Fig. 4 flow process;
Step 11, MSC or SGSN do not receive the report of the successful reception short message that the user returns in official hour, think that then short message sends failure; The reason that causes short message to send failure may be that the user terminal capacity overflows, or user terminal is unreachable, or Network Transmission is unusual, and error in data etc.;
Step 12, MSC or SGSN send failure reporting to the short message that SMS-GMSC returns this user; SMS-GMSC transmits short message and sends failure reporting to SC;
Step 13, SMS-GMSC are to the HLR of the user attaching status report that sends SMS message, and saving short message sends the identification information of error reason and this short message, and preserve the SC address etc. of this short message correspondence;
Step 14, SC are dealt into SMS-GMSC with the short message periodicity emphasis of appointment;
Step 15, SMS-GMSC find corresponding MSC or SGSN according to the user profile that receives short message, and short message is sent to this MSC or SGSN;
Step 16, MSC or SGSN send short messages to designated user.
If this user still fails success and receives short message, execution in step 11-16 then is till the user successfully receives this short message; If this user this time successfully receives short message, the step 11-14 in execution graph 4 flow processs then, after all users successfully received short message, this short message that SC will preserve was deleted.Reach preset threshold when retransmitting the short message number of times, perhaps the short message of preserving among the SC reaches the short message lifetime, then finishes transmission flow, and with this short message deletion.
Step 14-16 in the above-mentioned flow process, the retransmission mechanism of SC have two kinds of situations: a kind of SC of being periodicity emphasis short-message sending, till the user successfully receives this short message or reaches the short message lifetime; When a kind of user of being initiated position updating request, HLR sends the user to SC can reach report again, and SC retransmits short message.
In the above-mentioned process step 5, after SMS-GMSC receives that the short message that carries dispatcher tabulation sends failure reporting, short message is sent to all users in dispatcher's tabulation according to point-to-point mode.
In general, when the user sent group transmittings short message, most group-calling service was all set up, and SC can preserve this short message, was directly sent SMS message by SMS-GMSC, and like this, the transmission delay of short message will reduce.
Do not save short message at this SC, under the situation that group calling has been set up, set up according to group calling in the prior art then that the transmission flow of group transmittings short message sends SMS message under the situation; If because network side causes transmission to be failed unusually, then SC can obtain short message again and resends in process of transmitting, its flow process is:
Referring to Fig. 6, short message sends the flow chart of failing under the situation for group calling of the present invention has been set up, and SC does not preserve earlier this short message after receiving the short message of transmit leg, carry out following steps:
The short message that step 1, SC will have group call reference sends to SMS-GMSC;
Step 2, SMS-GMSC according to short message with group call reference inquiry external data base or HLR, find the A-MSC address of this VGCS business; The short message that will have group call reference sends to corresponding A-MSC;
Current attribute and dispatcher's tabulation of this group calling of inquiry in the corresponding GCR of step 3, A-MSC;
Step 4, if A-MSC is after sending the group calling status poll to GCR, do not receive response message, then to the SMS-GMSC transmission failure reporting that sends SMS message, the failure cause that carries in the report is whether to set up other irrelevant network failure with group calling, as link failure etc., and carry the short message of this transmission failure;
Step 5, SMS-GMSC transmit short message to SC and send failure reporting, and SC stores the short message that carries in this failure reporting, and send this short message according to a group short message transmission flow of setting up under the situation again.
If send failure once more, then repeat above-mentioned steps 1-5; If send successfully, its flow process is with the step 1-9 in Fig. 2 flow process.Reach preset threshold when retransmitting the short message number of times, perhaps the short message of preserving among the SC reaches the short message lifetime, then finishes transmission flow, and with this short message deletion.
This SC do not save short message earlier and the unfounded situation of group calling under, then sends successfully and the transmission two kinds of situations of failing:
Referring to Fig. 7, short message sends successful flow chart under the situation for group calling of the present invention is not set up, and SC does not preserve earlier this short message after receiving the short message of transmit leg, carry out following steps:
The short message that step 1, SC will have group call reference sends to SMS-GMSC;
Step 2, SMS-GMSC according to short message with group call reference inquiry external data base or HLR, find the A-MSC address of this VGCS business; The short message that will have group call reference sends to corresponding A-MSC;
Current attribute and dispatcher's tabulation of this group calling of inquiry in the corresponding GCR of step 3, A-MSC;
Step 4, GCR return to dispatcher's tabulation of state information, R-MSC tabulation and this group calling of A-MSC this " group calling is not set up as yet ";
After step 5, A-MSC receive the state information of this " group calling is not set up as yet ", do not receive the short message that SMS-GMSC sends, and send the report of group calling short message failure to SMS-GMSC, carrying failure cause is the still unfounded identification information of group calling, and carries dispatcher's tabulation of this group calling;
Step 6, SMS-GMSC send the report that the group calling short message is failed to SC, and carrying failure cause is the still unfounded identification information of group calling, and returns this content of short message simultaneously, and SC is kept at this locality after receiving this short message;
Step 7, takes place simultaneously with step 6, SMS-GMSC inquiry external data base or HLR obtain user profile, owing to will initiate short message service respectively individually at each user, so duplicate this short message for each user.SMS-GMSC comprises MSC or Serving GPRS Support Node (Serving GPRS Support Node, SGSN) address that the user is affiliated to the necessary information that HLR inquires about and obtains sending SMS message;
Step 8, SMS-GMSC send to short message the MSC or the SGSN at the current place of user;
After step 9, MSC receive short message, to Visited Location Registor (Visitor Location Register, VLR) inquiring user receives some authentication informations of short message, guarantees that the user can legal reception short message, SGSN does not need this operation;
Step 10, for validated user, MSC or SGSN send to the user with short message;
After step 11, user terminal successfully receive short message, return short message to affiliated MSC or SGSN and successfully send report;
Step 12, MSC or SGSN send successfully report to the short message that SMS-GMSC returns this user;
Step 13, SMS-GMSC send this user's short message status report to HLR;
After step 14, SMS-GMSC received all users' successful transmission report, sending SMS message to SC sent successfully report, and SC deletes this short message.
In the above-mentioned process step 5, after SMS-GMSC receives that the dispatcher tabulates, short message is sent to all users in the dispatcher tabulation according to point-to-point mode.
Referring to Fig. 8, short message sends the flow chart of failing under the situation for group calling of the present invention is not set up, and SC does not preserve earlier this short message after receiving the short message of transmit leg, carry out following steps:
Step 1-10, with the step 1-10 in Fig. 7 flow process;
Step 11, MSC or SGSN do not receive the report of the successful reception short message that the user returns in official hour, think that then short message sends failure; The reason that causes short message to send failure may be that the user terminal capacity overflows, or user terminal is unreachable, or Network Transmission is unusual, and error in data etc.;
Step 12, MSC or SGSN send failure reporting to the short message that SMS-GMSC returns this user; SMS-GMSC transmits short message and sends failure reporting to SC;
Step 13, SMS-GMSC are to the HLR of the user attaching status report that sends SMS message, and saving short message sends the identification information of error reason and this short message, and preserve the SC address etc. of this short message correspondence;
Step 14, SC send to SMS-GMSC with the short message of appointment;
Step 15, SMS-GMSC find corresponding MSC or SGSN according to the user profile that receives this short message, and short message is sent to this MSC or SGSN;
Step 16, MSC or SGSN send short messages to designated user.
If this user still fails success and receives short message, execution in step 11-16 then is till the user successfully receives this short message; If this user this time successfully receives short message, the step 11-14 in execution graph 7 flow processs then, after all users successfully received short message, this short message that SC will preserve was deleted.Reach preset threshold when retransmitting the short message number of times, perhaps the short message of preserving among the SC reaches the life time of its existence, then finishes transmission flow, and with this short message deletion.
Step 14-16 in the above-mentioned flow process, the retransmission mechanism of SC have two kinds of situations: a kind of SC of being periodicity emphasis short-message sending, till the user successfully receives this short message or reaches the short message lifetime; Another kind is user when initiating position updating request, and HLR sends the user to SC can reach report again, and SC retransmits short message.
Describe as can be known by above flow process, short message is kept among the SC, under the unfounded situation of group calling, if point-to-point in the user sends SMS message process, the user fails to receive short message, and SC can retransmit short message to this user.Therefore the present invention can guarantee under the unfounded situation of group calling, in the lifetime of short message, all users of short message can both receive short message, have improved the fail safe and the reliability of short message service in the group system, have strengthened the service quality of group system short message service.
Under the situation that group calling is set up, in SC, save short message, when A-MSC when R-MSC sends SMS message failure, SC retransmits this short message, has improved the fail safe and the reliability of short message service in the group system equally.
Because generally group calling is set up in the group-calling service, therefore, SC also can save short message in advance, only when group calling is not set up, send group calling by SMS-GMSC to SC by A-MSCS and do not set up report, carry short message and give SC, SC preserves this short message again, and adopts point to point system to send to the user.Like this, under the situation that group calling is set up, SC can not preserve this short message, directly sends by SMS-GMSC, thereby has reduced the time delay that short message sends.
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.
