Abstract
The present invention discloses a control method for occupying a reversed service channel by a cluster user. The method comprises that A, the priority of a cluster user in a cluster group is arranged in advance; B, when a reversed service channel does not occupy, a cluster service center causes a cluster user first sent a reversed calling request to occupy a reversed channel for communication; when the reversed service channel is occupied, the cluster service center causes the cluster user with high priority to occupy the reversed service channel for communication. The method ensures rapid access when the cluster service with high priority occupies the reversed service channel, and decreases the loads of BSS, and TSC or dispatching desks.
Description
Technical field
The present invention relates to the group service field of Digital Cellular System, particularly a kind of control method of reverse service channel in group user.
Background technology
It is a technological development direction of public mobile communication system that professional scheduling feature is provided on Digital Cellular System, support that the Digital Cellular System of group service is a kind of dispatching communication system of special use, this system can make many cluster users share the wireless channel of negligible amounts automatically, and dynamically uses these wireless channels.The digital cellular group system is compiled the up duration of all wireless channels effectively by the dynamic assignment of frequency, thereby for each cluster user provides maximum available labour time, and the obstruction of channel reduced to minimum.
In order to make Digital Cellular System support group service, must adopt forward traffic channel to share, reverse traffic channel is multiplexing at times by seizing of cluster user in the cluster group, thereby realizes reverse call function.Cluster user carries out the implementation process that reverse traffic channel seizes and is in the cluster group:
A plurality of cluster user buttons with push-to-talk (PTT) in step 1, the cluster group send oppositely seizes request message, and this message sends to cluster service center (TSC) or dispatching desk by base station sub-system (BSS);
Step 2, carry out the reverse conversation of certain cluster user of intrusion or interrupt the operations such as reverse conversation of certain cluster user by force, determine which cluster user can use reverse traffic channel to converse by TSC or dispatching desk;
Step 3, TSC or dispatching desk send the affirmation message that inserts reverse traffic channel message to this cluster user, periodically forbid inserting message to the broadcasting of forward direction Traffic Channel simultaneously by BSS, seize message in order to stop other PTT cluster user in the cluster group to send repeatedly, up to the reverse conversation that finishes this cluster user.
This process exists following shortcoming: shortcoming one, cluster user in the cluster group does not preestablish priority, so the cluster user in the cluster group can not be seized reverse traffic channel according to its priority level, thereby do not realize that the cluster user of high priority preferentially seizes the function of reverse traffic channel; Shortcoming two, because the cluster user quantity in the cluster group is not limit, therefore have a large amount of cluster users and carry out reverse traffic channel simultaneously and seize, therefore have a large amount of reverse call request message all to send to TSC or dispatching desk by BSS, this impact for BSS and TSC or dispatching desk is bigger.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of control method of reverse service channel in group user, this method can not only guarantee the quick access of high priority cluster user when seizing reverse traffic channel, and can reduce the load of BSS and TSC or dispatching desk.

Embodiment
In order to make the purpose, technical solutions and advantages of the present invention clearer, by the following examples and with reference to accompanying drawing, the present invention is described in more detail.
The present invention is that the cluster user in the cluster group distributes priority level, and cluster user is preserved the priority level of this cluster user, and TSC preserves the priority level of all cluster users in this cluster group.
When the present invention seizes reverse traffic channel at cluster user, promptly when the reverse traffic channel free time, when cluster user is initiated reverse call request, cluster user is regardless of priority in the cluster group, but adopts first come first served basis to guarantee to seize the quick access that reverse traffic channel is oppositely conversed.After this reverse traffic channel of end is seized, be that the cluster user of first access is when oppositely conversing, can also initiate reverse call request than the cluster user that this cluster user priority is high, the current cluster user of oppositely conversing is interrupted reverse conversation by force by TSC, and TSC distributes to reverse traffic channel the high cluster user of priority of initiating this reverse call request.
When the present invention takies at reverse traffic channel, have only than the high cluster user of oppositely conversing of cluster user priority and could initiate reverse call request, TSC is after the high reverse call request of each processing priority then, carry this reverse traffic channel of initiating the cluster user priority level of reverse call request by BSS to cluster user broadcasting and take message, make the cluster user that has only higher priority just allow to send reverse call request.
TSC among the present invention is the upper level control centre of BSS in the digital cellular group system, is not limited to concrete physical entity, as: can be integrated in the mobile switching centre (MSC).
Below illustrate the present invention with the cluster user for the PTT cluster user.
As shown in Figure 1, Fig. 1 carries out the flow chart that reverse traffic channel is seized for cluster user of the present invention, suppose that a part of cluster user in this cluster group belongs to BSS 1, belong to BSS1 as cluster user k, cluster user m and cluster user n, another part cluster user belongs to BSS2, the priority authority PR2 of the priority authority PR1 of cluster user k less than cluster user m is set, and the priority authority PR2 of cluster user m is less than the priority authority PR3 of cluster user n, and its detailed process is:
Step 100～102, when reverse traffic channel was idle, TSC was in the message of forward channel periodic broadcasting reverse traffic channel free time (Uplink State Ind (free)), and this message sends to all cluster users in this cluster group by BSS1 and BSS2;
Step 103～105, after cluster user in this cluster group is received this Uplink State Ind (free) message, send push-to-talk request (PTT setup request) message and carry out seizing of reverse traffic channel, the priority of carrying this cluster user in this PTT setup request message;
Step 106～108, when BSS1 receives first PTT setup request message, be assumed to be the PTT setup request message that cluster user k sends, judge whether this BSS1 cluster group lchannel preempting processing sign is true, if it is not true that this BSS1 cluster group lchannel preempting is handled sign, then represent the request of oppositely seizing that BSS1 is not handling, BSS1 cluster group lchannel preempting is handled sign and is set to true, preserve the priority level of cluster user k, transmit reverse call request (PTTuplink request) message of cluster user k to TSC, the follow-up PTTsetup request message that other cluster user of BSS1 under in the cluster group is sent abandons, as abandon the PTT setup request message of cluster user m transmission and abandon the PTT setup request message that cluster user n sends, BSS1 takies (Uplink State Ind (PR1)) message by forward channel periodic broadcasting reverse traffic channel simultaneously, the priority level that this Uplink StateInd (PR1) message is carried cluster user k makes the cluster user that is lower than cluster user k priority level forbid sending PTT setup request message; Be masked as very if BSS1 cluster group lchannel preempting is handled, do not handle the PTT setup request message of any cluster user;
By that analogy, BSS2 does identical processing to this PTT setup request message that the cluster user of affiliated BSS2 sends;
Step 109～112, after TSC receives first PTT uplink request message, judge whether TSC cluster group channel occupancy sign and TSC cluster group lchannel preempting processing sign all is true, suppose that first PTT uplink request message is sent by BSS1, it is not true that TSC cluster group channel occupancy sign and TSC cluster group lchannel preempting are handled sign, handle this PTT uplink request message, be changed to TSC cluster group channel occupancy sign and TSC cluster group lchannel preempting processing sign true, upgrade TSC cluster group information, soon the reverse traffic channel free time in the TSC cluster group information is converted to and takies, and the priority that the cluster user information that will send first PTT uplink request message write down and preserved this cluster user, the information and the priority of promptly preserving cluster user k.Return reverse call request response (PTT uplink ack) message to BSS1, simultaneously, TSC is to BSS1 and BSS2 broadcasting Uplink State Ind (PR1) message, the priority level that this Uplink State Ind (PR1) message is carried cluster user k, after handling PTT uplink request message, TSC cluster group lchannel preempting is handled sign be changed to vacation; If handling, TSC cluster group lchannel preempting is masked as very, then follow-up have other BSS to send PTT uplink request message to TSC, TSC directly responds oppositely conversation refusal (PTT uplink reject) message to this BSS, carrying cause value is TSC cluster group channel occupancy, directly respond PTT uplink reject message as TSC to this BSS2, as: BSS2 receive that TSC sends for PTT uplink reject message the time, check cause value, if cause value is a TSC cluster group channel occupancy, carry Uplink State Ind (PR1) message of cluster user k priority level to the cluster user broadcasting that belongs to BSS2, then BSS2 cluster lchannel preempting is handled sign and be changed to vacation, promptly BSS2 can receive the PTT setup request message of high priority cluster user; If cause value is not a TSC cluster group channel occupancy, then directly BSS2 cluster lchannel preempting is handled sign and be changed to vacation, promptly BSS2 can receive the PTT setup request message of high priority cluster user;
Step 113, when BSS1 receive that TSC sends for PTT uplink ack message the time, upgrade BSS1 cluster group information, promptly record sends the cluster user information of first PTT uplink request message, return reverse conversation to first cluster user k that sends PTT setup request message of affiliated BSS1 and confirm (PTT setup confirm) message, BSS1 cluster group lchannel preempting is handled sign be changed to vacation, promptly BSS1 can receive the PTT setup request message of high priority cluster user;
Step 114 after the cluster user k of first transmission PTT setup request message of affiliated BSS1 receives PTT setup confirm message, enters reverse talking state;
Step 115～117, when BSS1 or BSS2 receive the PTT setup request message that sends than the current cluster user that oppositely the cluster user k priority of conversation is high, as: the PTT setup request message of cluster user m sends to BSS1, BSS1 handles sign with BSS1 cluster group lchannel preempting and is changed to true, send the reverse conversation request of obtaining (the PTT uplink seizerequest) message of this cluster user m to TSC, and carried Uplink State Ind (PR2) message of this cluster user m priority level to the broadcasting of affiliated cluster user, send PTT uplink request message with the cluster user of forbidding being lower than and equal this priority level;
Step 118～120, after TSC receives PTT uplink seize request message, judge whether TSC cluster group lchannel preempting processing sign is true, if not, then this sign of TSC is set to very, send current reverse conversation to BSS1 and discharge (PTT uplink seize release ind (k)) message, the cluster user k of BSS1 interrupts oppositely conversation under making, and carries Uplink State Ind (PR2) message of cluster user m priority level simultaneously to each BSS broadcasting;
Step 121～122, after BSS1 receives PTT uplink seize release ind (k) message, send PTT uplink release message to cluster user k, interrupt the reverse conversation of cluster user k, and send current reverse conversation release affirmation (PTT uplink seize release ack (k)) message to TSC;
Step 123, TSC send oppositely conversation and obtain affirmation (PTT uplink seize ack) message, make cluster user m insert reverse traffic channel by BSS1, and TSC cluster group lchannel preempting is handled sign be changed to vacation, so that the cluster user of higher priority sends PTT setup request message;
Step 124～125, BSS1 upgrades BSS1 cluster group information, be the information of record clustering user m, as the priority of record clustering user m and cell information etc., send PTT setupconfirm message to cluster user m, BSS1 cluster group lchannel preempting is handled sign be changed to vacation, cluster user m enters reverse talking state.
The present invention can directly begin to carry out from step 115 when the current business channel occupancy.
In this process, periodically to terminal broadcasting Uplink State Ind message, indication reverse traffic channel state still takies (busy) for idle (free) for BSS1 and BSS2.When cluster user receive broadcasting be not Uplink State Ind (free) message the time, whether the priority level of judging self is lower than and equals the priority level that Uplink State Ind (priority) message is carried, if, forbid sending PTT setup request message, up to receiving Uplink State Ind (free) message; Otherwise, can continue to send PTT setup request message.When cluster user receive broadcasting when Uplink StateInd (free) message, the cluster user of priority all can send PTT setup request message arbitrarily.
In this process, can also after sending reverse call request message, TSC set regularly time threshold of timer at BSS, BSS judges the affirmation message of whether both not received TSC in time threshold, do not receive the reverse conversation refuse information of TSC yet, be changed to vacation if then BSS cluster group lchannel preempting is handled sign; Otherwise stop this timer timing after receiving wherein any message.
As shown in Figure 2, Fig. 2 carries out the flow chart that reverse traffic channel discharges for cluster user of the present invention, suppose that a part of cluster user in this cluster group belongs to BSS1, belong to BSS1 as cluster user k, cluster user m and cluster user n, another part cluster user belongs to BSS2, the priority authority of the priority authority of cluster user k less than cluster user m is set, and the priority authority of cluster user m is less than the priority authority of cluster user n, and its detailed process is:
Step 200～201 take cluster user that reverse traffic channel oppositely converses and discharge the PTT button and finish reverse talking state, send PTT uplink release request message to its BSS1;
Step 202, BSS1 sends to TSC with this PTT uplink release request message;
Step 203～204, TSC upgrades cluster group state, soon the reverse traffic channel in the TSC cluster group information takies and is converted to the free time, and the cluster user information that will take reverse traffic channel is deleted, to BSS1 and BSS2 broadcasting Uplink State Ind (free) message, TSC cluster group channel occupancy sign is changed to vacation;
Step 205, BSS1 and BSS2 BSS1 cluster group lchannel preempting are handled sign respectively and BSS2 cluster group lchannel preempting processing sign is changed to vacation, to cluster user broadcasting Uplink State Ind (free) message that belongs to BSS1 and BSS2;
Step 206, reverse traffic channel is in idle condition, can carry out seizing of reverse traffic channel once more after the cluster user of priority level is received Uplink State Ind (free) message arbitrarily.
TSC of the present invention can also replace with dispatching desk.
When cluster user was not operated in the PTT pattern, the method that cluster user is seized reverse traffic channel by cluster user of the present invention can also enter the data communication state.
The present invention does not distinguish the priority of cluster user in the cluster group in the reverse traffic channel preemption processes, insert cluster user according to first come first served basis and oppositely converse, and has guaranteed to insert the time delay minimum of reverse traffic passage; The present invention is also in preemption processes, BSS only handles first PTT uplinkrequest message, directly carry out discard processing for follow-up reverse call request, do not transmit subsequent P TT uplink request message to TSC, do not send corresponding response message yet, guaranteed the simple and reliable of BSS, TSC and cluster user processing procedure to cluster user.
The present invention is in the reverse communication process of current cluster user, the cluster user of higher priority can be initiated PTT uplink request message, interrupt the reverse conversation of current cluster user, the cluster user of assurance higher priority is linked into reverse traffic channel immediately and oppositely converses, and makes the cluster user of high priority can preferentially obtain service.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being made within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
