Specific embodiment
In order that the purpose of the application, technological means and advantage become more apparent, below in conjunction with accompanying drawing to this Shen
Please be described in further details.
In TD-LTE group systems, pre-occupied priority call is the call business initiated under urgent and material circumstance,
Promoter should possess pre-occupied priority call authority, system can tolling breakdown low level calling by way of preempting resources,
Preferentially ensure the distribution of its resource.Pre-occupied priority call includes that the preferential individual calling of preemption, preferential group of preemption are exhaled.
The authority that existing pre-occupied priority call scheme has network side is pointed out, but lacks the authority prompting of terminal itself,
User operability is poor.Existing pre-occupied priority call scheme is distinguished without the priority clearly with urgent call.It is existing
There is pre-occupied priority call scheme without the difference clearly with emergence call service on called subscriber.Just because of upper
Problem is stated, causes current pre-occupied priority call business ease for use poor, and it is fuzzy with emergence call service difference.
The implementation method of the pre-occupied priority call that the application is provided includes：When colony terminal is registered, colony terminal is received
The authority that cluster core net sends indicates that the authority is indicated for identifying whether the terminal possesses pre-occupied priority call authority；
Colony terminal indicates that activation or restriction user are operated using pre-occupied priority call according to the authority for receiving.When the power for receiving
When limit sign terminal does not possess pre-occupied priority call authority, limit user and operated using pre-occupied priority call；When connecing
The authority sign terminal of receipts possesses pre-occupied priority call authority, and activation user is operated using pre-occupied priority call.
Specifically, before pre-occupied priority call business is initiated, cluster core net informs that user weighs in endpoint registration
Limit is indicated, for identifying whether user possesses preemption limit priority, specifically, the authority is indicated can be by note
Volume response message is carried；Terminal indicates that activation or restriction user use preemption priority service according to authority.Activation
Pre-occupied priority call operation mode can be：Terminal is activated on interface and lights preemption priority service, makes user
The business can be initiated；Limiting the mode of preemption priority call operation can be：Terminal limits drawing ash on interface
Preemption priority service, makes user to initiate the business.Specifically preempting preferential registration operation flow can be such as Fig. 2
It is shown, specifically include：
Step 201, terminal UE booting up attachment；
Step 202, terminal UE initiates cluster login request message；
Step 203, cluster core net TC replys UE cluster registration reply messages, wherein carry preemption preferentially exhaling
Capability identification is, identifies whether the terminal UE has pre-occupied priority call authority；
Step 204, terminal UE activates or limits preemption priority service according to pre-occupied priority call capability identification.
If terminal use possesses the authority, terminal is activated on interface and lights preemption priority service；If terminal
User does not possess the authority, and terminal limits drawing ash preemption priority service on interface.To be preempted preferentially by above-mentioned
Ash is drawn in operation, it is possible to use family cannot be input into pre-occupied priority call instruction, also cannot just carry out pre-occupied priority call.
Or, it is also possible to ash preemption priority service is not drawn, but after the pre-occupied priority call for receiving user is indicated,
Terminal notifying user haves no right to carry out pre-occupied priority call, does not also send pre-occupied priority call to core net and asks.And
For the terminal of activation pre-occupied priority call authority, after the pre-occupied priority call for receiving user is indicated, to core
Heart net sends pre-occupied priority call request.
On the basis of above-mentioned pre-occupied priority call implementation method, it is preferable that can also be to pre-occupied priority call
Priority and call number do further setting, clearly to distinguish its difference with urgent call.
In service priority distribution, group system can be only second to promptly exhale for pre-occupied priority call distribution rank
Business is, higher than other call business in addition to urgent call and pre-occupied priority call.Other business such as common list
Exhale, group is exhaled, generally call, monitor.
On called object, (individual calling number or group are exhaled corresponding to a number to be different from the called number of urgent call
Number), pre-occupied priority call called number can be other any individual callings number (containing dispatching desk number), or
Oneself be located the group number arbitrarily organized.
Specifically, when the user for possessing pre-occupied priority call authority is initiated to certain list on the interface that activation is lighted
When wailing the pre-occupied priority call business of code, if the number user is carrying out emergence call service, because of preemption
Priority Call priority is less than emergence call service, and now terminal refuses this pre-occupied priority call.If this number
Code user carries out other call business less than pre-occupied priority call, and called subscriber will interrupt other calling industry
Business, then accesses this pre-occupied priority call.If the number user is also carrying out pre-occupied priority call, eventually
Hold according to the priority for comparing two callings to determine to answer that pre-occupied priority call.Specifically preempt preferential individual calling
Operation flow as shown in figure 3, including：
Step 301, possesses the terminal UE 1 of pre-occupied priority call authority preferential by preemption that terminal interface is activated
Call operation is initiated the preferential individual calling of preemption and sets up request message；
Step 302, cluster core net TC judges that the terminal possesses after pre-occupied priority call authority, if it is determined that quilt
Cry terminal UE 2 in Idle state, then initiate SR processes, set up the connection of eating dishes without rice or wine of terminal called；
Step 303, cluster core net TC sends the preferential individual calling of preemption and sets up request message to terminal called UE2；
Step 304, terminal called UE2 is received and set up after request message, if carrying out emergence call service
Or the pre-occupied priority call business that priority is same or higher, then refuse this pre-occupied priority call, to cluster core
Heart net and calling terminal answering call set up refuse information, this time pre-occupied priority call service fail；
Step 305, terminal called UE2 is received and set up after request message, if carrying out other call business
Or the pre-occupied priority call business that priority is lower, then call release message is sent to cluster core net, disconnect former
Call business；
Step 306, sends call setup and confirms to disappear to the cluster core net and calling terminal of this pre-occupied priority call
Breath, receives this pre-occupied priority call.
When the user for possessing pre-occupied priority call authority initiates to wail code to certain group on the interface that activation is lighted
When preempting preferential group-calling service, if the group in some number users carrying out emergence call service, now this
A little number users will refuse this time preferential group of preemption and exhale, and this time group calling will not include and these number users
Call session.If some number users carry out other call business less than pre-occupied priority call in the group,
Now these called subscribers will interrupt current sessions business, access and this time preempt in the preferential group of call session exhaled.
If some number users are also carrying out pre-occupied priority call in the group, terminal is excellent according to two callings of comparison
First level is determining to answer that pre-occupied priority call.Preferential group-calling service flow process is specifically preempted as shown in figure 4, bag
Include：
Step 401, possesses the terminal UE 1 of pre-occupied priority call authority preferential by preemption that terminal interface is activated
Preferential group of call operation initiation preemption is exhaled and sets up request message；
Step 402, cluster core net TC judges that the terminal possesses pre-occupied priority call authority；
Step 403, cluster core net TC is set up group call uplink and is carried for caller terminal UE 1；
Step 404, cluster core net TC exhales the foundation of downlink bearing to associated base stations initiation group.Base station each first
Group is set up parallel exhales context；
Machine group-calling beep-page message is initiated in step 405, each base station, wherein comprising pre-occupied priority call priority；
Step 406, each base station initiation group exhales foundation to indicate message；
Step 407, if to carry out the lower preemption of other call business or priority preferential for certain terminal called
Call business, then exit former call business, and receive this time preferential group of preemption and exhale paging；
Step 408, if certain terminal called is carrying out emergence call service or higher pre- of priority level is dominant
First call business, then this time paging is exhaled in preferential group of preemption to refusal.
Step 409, cluster core net TC initiates right of speech notification procedure, notifies that current utterance power owner can be with
Start speech.
The implementation method of pre-occupied priority call is embodied as in above-mentioned as the application.Be embodied as can by above-mentioned
See, in the application, it is to avoid not possess and the brought time is refused by network side after the terminal originated calls of authority
Delay.Terminal registration when be apprised of with preemption limit priority, can activate accordingly or limiting terminal interface on
Preemption priority service, when user runs into urgent or important thing prepares to use pre-occupied priority call, such as sees boundary
Priority service is preempted on face to be prohibited, then abandon using the business, or, terminal is carried after user initiates request
Show that user is inoperable, it is to avoid initiate to refuse brought time delays, terminal interface by network side after calling
Operability is good, improves the use feeling of user.
Further, the preferential implementation method of preemption in the application specify that preemption preferential and urgent call, other
The priority difference of business, specify that the difference of the business with regard to called subscriber of pre-occupied priority call and urgent call.
The user for possessing pre-occupied priority call authority is set to initiate one-level lower than urgent call rank but can be used for the quilt for calling
It is user wider business.In group system, on the one hand such business gives a few users and more provides
Source takes authority and call is free, and on the other hand avoid preemption preferentially affects on the call of emergence call service.
Above-mentioned advantage is optimized for pre-occupied priority call to be more easy to use, more often use, more preferable business.
Presently preferred embodiments of the present invention is the foregoing is only, it is all in the present invention not to limit the present invention
