Setting, call parameter in limited time below for call parameter in limited time notify that terminal and group exhale middle call limit
Three aspects that realize of Shi Gongneng are specifically described technical scheme.Following example are with TD-LTE broadband collection
As a example by group communication system, but the design philosophy of the application scheme is not limited to this system, is also applied for various broadbands collection
Group's private network system.
(1), the setting of call time in limited time
The incidence relation of user and group is configured when user contracts, or is set by dynamic reorganization operation
Put.
The call time in limited time can be arranged by cluster core net when group membership contracts, and arranges for each group member
One single right of speech maximum length in time (FloorDuration) parameter indicates this member call in group in limited time.
Under dynamic reorganization scene, if certain user adds in new group by dynamic reorganization, FloorDuration
Parameter issues the dynamic reorganization message informing of cluster core net to cluster core net by dispatching desk, is below existing D
A concrete example of dynamic reorganization message in interface (dispatching desk and cluster core net interface) standard:
D interface signaling plane between dispatching desk and cluster core net (T-CN) uses Session Initiation Protocol, dynamic reorganization
During additions and deletions member, dispatching desk sends SIP (MESSAGE) message, the ptt of this sip message to cluster core net
Extension header carries dynamic reorganization operation mark, XML format extension message body in carry increase or delete
Member/group mark, for each member's number or group number, carries operation mark (operate), if operation
Mark value is Add, and dynamic group member or group are added in instruction；If operation mark value is Delete, then will
Dynamic group member or group are deleted.The embodiment of the present application (includes user for each terminal increased newly in group
Equipment and dispatching desk) record, increase FloorDuration parameter and indicate this terminal single right of speech in this group
Long duration, FloorDuration parameter can be set to different value according to user's significance level in group,
The user that significance level is the highest, its corresponding single right of speech maximum length in time is the longest.If the user while tool in group
There is right of speech priority (TalkPriority), it is preferred that FloorDuration parameter can be the most grading with right of speech
Row association, the terminal that right of speech priority is the highest, its corresponding FloorDuration parameter is the biggest.
Message examples is as follows:
Table 1
In dynamic reorganization MESSAGE message, the concrete meaning of each parameter is as shown in table 1.
(2), call parameter in limited time notifies terminal
If terminal type is subscriber equipment (UE), call parameter in limited time obtains its affiliated group at subscriber equipment
UE is notified during information.Specifically, for TD-LTE broadband cluster private network system, by NAS interface (collection
Group's core net and UE interface) point-to-point group information updating process notifications is to UE.Group information updating process bag
The group letter that after including the group information updating process and dynamic reorganization that after UE succeeds in registration, network side is initiated, network side triggers
Breath renewal process.
The group information updating flow process that the embodiment of the present application provides is as in figure 2 it is shown, comprise the steps:
Step 201: subscriber equipment sends group information updating request message to cluster core net (T-CN).This step
(present invention does not revise the group information updating that UE may initiate to rapid optional step defined in existing NAS standard
Request scene and message).
Step 202: cluster core net sends group information updating order (Group Information to subscriber equipment
Update Command) message.
If scene is UE succeed in registration after network side initiate group information updating, now updating type be complete or collected works more
Newly, this message carries the information of each group belonging to subscriber equipment with tabular form, and each group includes group mark, group
Another names etc., the embodiment of the present application extends FloorDuration cell instruction user in this set for each group
In limited time, the cell comprised in each group is as shown in table 2 in call.By Group Information Update Command
In message, the group under Groups List cell (Group List) increases information (Group Add Information) cell
User's single right of speech maximum duration in this set is notified UE.
If scene is the group information updating process that network side triggers after dynamic reorganization, now UE passes through dynamic reorganization
Operation adds new group to, or deletes from group, or obtains the group letter after the group information after updating, and registration
Breath renewal process compare, now in message, updating type cell value could be arranged to incremental update, only carry with
The group information that this UE incidence relation or group attribute change, Group Information Update Command
Under Group List cell in message, for each group being newly added, Group Add Information cell is taken
Band FloorDuration parameter.
Note: for adapting to increase, delete, revise information about firms in group simultaneously, in existing standard, Group
The group information carried under Group List cell in Information Update Command message, can be to increase
Group information (Group Add Information cell), delete group information (Group Del Information
Cell) and the group information (Group Modify Information cell) of amendment, Group List cell can wrap
Containing 1 to 20 Group Add Information/Group Del Information/Group Modify
Information cell.

Step 203: subscriber equipment returns group information updating response to cluster core net.
After UE receives the Group Information Update Command message that network side sends, carry out group letter
Breath processes, group information new after preserving its affiliated group information or dynamic reorganization, replys Group to network side
Information Update Response message.
If terminal type is dispatching desk, when dispatching desk belongs to group membership, if response of succeeding in registration is carried
Group information belonging to dispatching desk, FloorDuration parameter can be taken in the group information that response of succeeding in registration returns
Band；If not carrying the group information belonging to dispatching desk in described registration response, dispatching desk by inquiring about or can be ordered
The process of readding obtains the group information that it is affiliated, carries FloorDuration parameter in group information.
(3), the realization of call timing function
In group-calling process, call intervalometer, group member in limited time are safeguarded in cluster core-network side and group membership side simultaneously
During for UE, the realization of call timing function is as it is shown on figure 3, comprise the steps:
Step 301: subscriber equipment (UE) is to cluster core net (T-CN) application sending the right words (FLOOR
REQUEST) message application right of speech.
This step is optional step, and network side can actively initiate right of speech licensing process in the case of UE queues up,
Now need not move through the right of speech request process of UE.
Step 302: if right of speech is licensed to this subscriber equipment by cluster core net decision-making, cluster core net is to user
Equipment sends right of speech mandate (Floor Grant) message, and subscriber equipment starts first timer after receiving authorization messages,
The value of this intervalometer is set to user's FloorDuration duration in this set；
Step 303: subscriber equipment sends FLOOR GRANT ACK message to cluster core net and confirms,
Cluster core net starts second timer after receiving this message, and the value of intervalometer is set to FloorDuration duration；
Step 304: during speech, user equipment side and cluster core-network side safeguard first timer and second respectively
Intervalometer, the first timer of user equipment side is mainly used in right of speech timing and points out user, cluster core-network side
Second timer for right of speech control；User talks time-out, stops after the second timer time-out of cluster core net
Only, triggering right of speech release, cluster core net sends right of speech release (FLOOR RELEASE) message to UE,
And release speech right resource；
Step 305:UE side first timer before receiving FLOOR RELEASE message has timed out stopping, receiving
After this message, send right of speech release to cluster core net confirm that (FLOOR RELEASE ACK) message is carried out
Confirm, and release speech right related resource.
Subscriber equipment starts the 3rd intervalometer while first timer time-out, stops after receiving right of speech release message
Only the 3rd intervalometer；If not receiving right of speech release message before the 3rd timer expiry, local release speech right phase
Close resource.This intervalometer is used for abnormal protection, it is ensured that UE side and network side right of speech state consistency under abnormal scene.
This process do not affect normal subscriber equipment initiate right of speech release flow process, under this scene cluster core net and
If user equipment side, during authority, intervalometer all stops after right of speech discharges successfully.
If terminal type is dispatching desk, as shown in Figure 4, dispatching desk (DC) is to cluster core net (T-CN)
Send SIP (re-INVITE) message application right of speech, if right of speech is licensed to DC by T-CN decision-making, to DC
Sending SIP (200OK) message, carry right of speech mandate mark, DC starts first timer and to T-CN after receiving
Sending SIP (ACK) message to confirm, T-CN starts second timer after receiving confirmation message.Conversed
In journey, dispatching desk and cluster core net safeguard that right of speech is prescribed a time limit intervalometer simultaneously, stop after the second timer time-out of T-CN side
Only, triggering right of speech release, send SIP (re-INVITE) message release speech right to DC, DC sends out to T-CN
Sending SIP (200OK) message to respond, T-CN sends SIP (ACK) message authentication right of speech to DC and releases
Put.
Based on inventive concept similar to the above, technical scheme is equally applicable to the call exhaling single group
Time limits.For calling talk timing function, similarly, calling parameter in limited time passes through group information updating
Flow process notifies that subscriber equipment, user equipment side and cluster core net startup group after group exhales foundation exhales timing in limited time
Device, initiates calling release after this timer expiry of cluster core net, this intervalometer of user equipment side is based on calling
Time and prompting user, user equipment side is receiving call release message or is exhaling in limited time after timer expiry one in group
Call release message, local call release is not received in the section time.
The present invention proposes the implementation method of timing function of conversing in the cluster private network system of a kind of broadband, has following
Advantage:
1, can be that each member distributes an independent call and prescribes a time limit time notify terminal in group, it is achieved
Flexible allocation and control to group member's duration of call, user can according to this duration control flexibly speech content and
Rhythm, improves Consumer's Experience；
2, cluster core net and user equipment side safeguard call intervalometer in limited time simultaneously, it is ensured that cluster core-network side
With end side right of speech state consistency；
3, existing flow process and interface message are used, only by message extends cell realization, to system schema
Change less, it is achieved simple.
