Embodiment
The dynamic method flow diagram of restructuring in the group system that Fig. 1 provides for one embodiment of the invention.As shown in Figure 1, the method for the present embodiment comprises:
Step 101, switch receive group's CAMEL-Subscription-Information that the user contracting data server sends, and in the unclosed situation of buffering timer timing that has started, will cushion timer and reset.
In specific implementation process, when needs were dynamically recombinated, each terminal can be contracted in advance, and group's CAMEL-Subscription-Information is stored on the user contracting data server.Group's CAMEL-Subscription-Information mainly comprises: the group information that the user contracts, user's information, the authority information of user in group etc.Wherein, user's group information of contracting mainly refers to group name, group identification etc.; User's information spinner will refer to number, user's name, terminal iidentification of the terminal that the user is corresponding etc.; The authority information of user in group is such as being: urgent call authority, ordinary call authority, called authority etc.
For the user contracting data server, when there being new group to set up, perhaps ought exist group information to change, such as having the New Consumers terminal to add or when withdrawing from etc., the user contracting data server will send to vicissitudinous group CAMEL-Subscription-Information the switch in core net.The switch of core net receives group's CAMEL-Subscription-Information that the user contracting data server sends.Wherein, the foundation of new group, exist the operations such as change of group information to be carried out by the keeper, user contracting data server transmission group CAMEL-Subscription-Information can be triggered by the keeper, but is not limited to this.In addition, the keeper can also be responsible for the user contracting data server is safeguarded etc.
When the new foundation of group or change occur when more frequent at short notice, the user contracting data server at short notice will be continually sends group's CAMEL-Subscription-Information to the switch of core net, and this will cause the user contracting data server to send to group's CAMEL-Subscription-Information of switch to concentrate at short notice.In the prior art, in a single day the switch of core net receives group's CAMEL-Subscription-Information, will immediately the group's CAMEL-Subscription-Information that receives be sent to the terminal in group.A plurality of groups have been added simultaneously for a terminal, and a plurality of groups that this terminal adds are when all changing at short notice, the switch of core net will send group's CAMEL-Subscription-Information to this terminal at short notice continually, when acquiring a certain degree, will cause the space interface signaling storm.In order to address this problem, the switch of the present embodiment presets a buffering timer, and preset the timing of buffering timer, and regulation buffering timer just sends to corresponding terminal with the group's CAMEL-Subscription-Information that receives after regularly finishing, and realizes that by the operating characteristic that buffering timer and regulation buffering timer is set the subtend terminal sends the buffering of group's CAMEL-Subscription-Information.Wherein, the timing of buffering timer can arrange according to practical application scene adaptability, and allows to modify.
Wherein, switch starts the buffering timer when starting or when receiving group's CAMEL-Subscription-Information for the first time.
In actual application, switch receives group's CAMEL-Subscription-Information that groups of users subscribed services device sends, if the buffering timer that has started when receiving group's CAMEL-Subscription-Information regularly finishes, will cushion timer and reset, be about to cushion the timer zero clearing, the buffering timer is restarted regularly.When the user contracting data server concentrate to send group's CAMEL-Subscription-Information at short notice, switch will receive group's CAMEL-Subscription-Information frequently like this, and can will cushion the timer replacement continually before the buffering timer regularly finishes.
By as seen above-mentioned, when the user contracting data server is concentrated when sending group's CAMEL-Subscription-Information to switch at short notice, because the buffering timer can just be reset before regularly finishing, make switch and needn't send group's CAMEL-Subscription-Information to terminal frequently immediately in the situation that receive continually group's CAMEL-Subscription-Information, realized the buffering to group's CAMEL-Subscription-Information.
Step 102, when buffering after timer regularly finishes, switch obtains all group CAMEL-Subscription-Information corresponding with each terminal iidentification according to the terminal iidentification in the group's CAMEL-Subscription-Information that receives.
When the buffering timer regularly finishes, illustrate that the user contracting data server did not send group's CAMEL-Subscription-Information again in the timing of buffering timer, show that the user contracting data server centered sends this time operating of group's CAMEL-Subscription-Information and finishes.At this moment, switch can issue the group's CAMEL-Subscription-Information that receives to terminal.
In this step, the terminal iidentification that switch comprises according to each group's CAMEL-Subscription-Information take terminal as according to classifying, obtains all group CAMEL-Subscription-Information corresponding with each terminal with group's CAMEL-Subscription-Information of receiving in during this period of time.Wherein, each terminal iidentification is unique corresponding to a terminal, therefore the group CAMEL-Subscription-Information corresponding with each terminal iidentification is the group CAMEL-Subscription-Information corresponding with each terminal.Each terminal can add a plurality of groups simultaneously.
By aforesaid operations, switch gets all group's CAMEL-Subscription-Information that need to send to each terminal, sends to terminal to lay the foundation all group's CAMEL-Subscription-Information for subsequent step is disposable.
Further, when buffering after timer regularly finishes, the switch buffering timer of need to resetting thinks that follow-up continuation receives and sends group's CAMEL-Subscription-Information and prepares.Wherein, switch can be reset according to the triggering of the group's CAMEL-Subscription-Information that receives again and be cushioned timer.Perhaps switch can also be according to practical situations, and a reboot time interval is set, and the time after the buffering timer regularly finishes resets and cushions timer when reaching the reboot time interval.
All group CAMEL-Subscription-Information corresponding with each terminal iidentification that step 103, switch will obtain send to respectively the terminal corresponding with each terminal iidentification, to realize dynamic restructuring.
A dynamic group set up process, the switch of core net needs the group's CAMEL-Subscription-Information with this dynamic group send to respectively each terminal in this dynamic group, could really realize dynamically restructuring.
For the terminal that adds simultaneously a plurality of groups, switch by with terminal between all group's CAMEL-Subscription-Information of eating dishes without rice or wine once this terminal is corresponding all send to this terminal.Often receive group's CAMEL-Subscription-Information in this send mode and prior art and compare with regard to the mode that sends group's CAMEL-Subscription-Information, significantly reduced by eating dishes without rice or wine to the number of times of terminal transmits information.Solve switch and concentrated at short notice the problem that frequently sends group's CAMEL-Subscription-Information when receiving group's CAMEL-Subscription-Information collection to terminal, and then solved the space interface signaling storm problem that therefore causes.
In the present embodiment, switch in core net is when receiving group's CAMEL-Subscription-Information, to cushion timer resets, only have after the buffering timer regularly finishes, just according to the terminal iidentification in group's CAMEL-Subscription-Information, obtain all group's CAMEL-Subscription-Information corresponding to each terminal from received group's CAMEL-Subscription-Information, then all group's CAMEL-Subscription-Information that each terminal is corresponding once send to each terminal respectively, to realize dynamic restructuring.in the present embodiment, switch is by arranging the buffering timer, just reset when often receiving group's CAMEL-Subscription-Information and cushion timer, and only after regularly finishing, the buffering timer just issues the mode of group's CAMEL-Subscription-Information to terminal, make the user contracting data server concentrate at short notice when sending group's CAMEL-Subscription-Information to switch, switch concentrates the group's CAMEL-Subscription-Information that receives to obtain buffering, solve switch and sent continually the problem of group's CAMEL-Subscription-Information to terminal, thereby avoided sending to terminal the space interface signaling storm that group's CAMEL-Subscription-Information causes continually at short notice because of switch.
Further illustrate, in the present embodiment, after the buffering timer regularly finished, switch issued the process of group's CAMEL-Subscription-Information to terminal, and the process that receives group's CAMEL-Subscription-Information with the switch continuation is separate, does not influence each other.
Further, in order to prevent that the user contracting data server from ceaselessly sending group's CAMEL-Subscription-Information to switch in long-time, cause switch the group's CAMEL-Subscription-Information that receives can't be sent to terminal in long-time, the switch of the present embodiment also is provided with a counter, be used for statistics buffering timer from starting to the number of times that regularly is reset between end, also be provided with simultaneously replacement number of times thresholding.When the replacement number of times of buffering timer reaches replacement number of times thresholding, the group's CAMEL-Subscription-Information that receives some is described, and failed for some time to send group's CAMEL-Subscription-Information to terminal, the old friend changes planes the buffering timer is set to regularly done state by current definition status, regularly finish so that cushion timer, so that send the group's CAMEL-Subscription-Information that receives to terminal.Simultaneously, it is clear 0 that switch will cushion the replacement number of times of timer, so that after the buffering timer is reset or restarts, and the number of times that is reset of count buffer timer again.Afterwards, receive again group's CAMEL-Subscription-Information of user contracting data server transmission when switch after, will cushion timer and reset.
The dynamic method flow diagram of restructuring in the group system that Fig. 2 A provides for another embodiment of the present invention.As shown in Fig. 2 A, the method for the present embodiment comprises:
Step 201, when change occurs in the group that has new group to set up or to exist, the user contracting data server sends group's CAMEL-Subscription-Information to the switch of core net.
Wherein, group's CAMEL-Subscription-Information of described transmission is group's CAMEL-Subscription-Information of newly-established group or group's CAMEL-Subscription-Information that change occurs.
The switch of step 202, core net receives group's CAMEL-Subscription-Information that the user contracting data server sends, and will cushion timer and reset when receiving group's CAMEL-Subscription-Information.
After the buffering timer of resetting, there is again new group to set up or when having existed group that change occurs, the user contracting data server can continue to send group's CAMEL-Subscription-Information of newly-established group or group's CAMEL-Subscription-Information of change occurs to the switch of core net.And exchange opportunity continues to receive group's CAMEL-Subscription-Information.
After the buffering timer regularly finished, switch obtained all group's CAMEL-Subscription-Information corresponding to each terminal, and the download sign of each terminal is set to very, need to issue group's CAMEL-Subscription-Information to these terminals with expression.Simultaneously, after the buffering timer regularly finished, switch was reset and is cushioned timer.
In this process, switch issues group's CAMEL-Subscription-Information to terminal and is independent of each other with the process that receives new group's CAMEL-Subscription-Information.
Step 204, all group's CAMEL-Subscription-Information that switch is corresponding with each terminal iidentification send to the terminal corresponding with each terminal iidentification, to realize dynamic restructuring.
Wherein, according to the state of terminal, switch can send to each terminal with group's CAMEL-Subscription-Information in different ways.
Concrete, when terminal was in connection (Connection) state, switch can pass through Non-Access Stratum (Non-Access Stratum; Referred to as: NAS) flow process sends to corresponding terminal with group's CAMEL-Subscription-Information.Concrete, all group's CAMEL-Subscription-Information that switch is corresponding with terminal send to the base station, and the base station sends download instruction to terminal; After terminal receives the download instruction of base station, download corresponding all group's CAMEL-Subscription-Information from the base station, and return to the base station to download after downloading end and complete message; After message is completed in the download that the base station receives terminal, return to the download end to switch, thereby complete issuing of group's CAMEL-Subscription-Information.
When terminal is in the free time during (Idle) state, switch is initiated paging (PAGING) flow process to terminal, and notification terminal is set up signaling and connected.After switch and terminal were set up signaling and be connected, switch sent to this terminal by NAS message all group's CAMEL-Subscription-Information that terminal is corresponding.
When terminal not online (for example terminal closedown), switch can send to corresponding terminal by NAS message all group's CAMEL-Subscription-Information that terminal is corresponding after terminal is reached the standard grade.
In addition, switch also can be according to the download request of terminal, and all group's CAMEL-Subscription-Information terminal is corresponding by the NAS flow process send to terminal.
In above-mentioned each situation, switch all sends to terminal by the base station with group's CAMEL-Subscription-Information.
wherein, when if group's CAMEL-Subscription-Information that switch receives at short notice relates to great amount of terminals, concerning switch, just need to send respectively group's CAMEL-Subscription-Information to great amount of terminals, send group's CAMEL-Subscription-Information to great amount of terminals simultaneously for fear of switch and cause mass flow discrepancy weighing apparatus and space interface signaling storm, so that can be successfully that each terminal is corresponding all the group's CAMEL-Subscription-Information of switch all success send to each terminal, the present embodiment provides a kind of switch to send the execution mode of its corresponding all group's CAMEL-Subscription-Information to each terminal, be specially: switch presets the transmission cycle, for example sent once every 1 minute, and the terminal number that can send in good each transmission cycle of appointment in advance, for example specify in each transmission cycle and can only send group's CAMEL-Subscription-Information to 20 terminals.Switch can be within the default transmission cycle, to specifying several terminals to send group's CAMEL-Subscription-Information.
Based on above-mentioned execution mode, when terminal is in connection status, switch can start every 1 minute a NAS flow process, and selects from residual terminal and specify several, by the NAS flow process, corresponding all the group's CAMEL-Subscription-Information of each terminal is sent to respectively the terminal of selecting.Wherein, residual terminal refers to the terminal that also group's CAMEL-Subscription-Information do not sent to according to sending the cycle switch.
When terminal was in idle condition, switch sent the process of group's CAMEL-Subscription-Information according to the default transmission cycle as shown in Fig. 2 B to terminal.This execution mode comprises:
Step 2a, when default transmission cycle arrives, the switch of core net sends paging (PAGING) message to the base station that covers terminal.Wherein, the number of the PAGING message that sends in each transmission cycle is the terminal number of appointment, is set to N, and wherein N is the integer more than or equal to 1.As shown in Fig. 2 B, within the current transmission cycle, N the PAGING message that switch sends to the base station is respectively PAGING message to a N PAGING message.
Step 2b, base station are transmitted to N corresponding terminal with PAGING message.
In the present embodiment, corresponding terminal is N.
After step 2c, each terminal receive PAGING message, set up signaling by base station and switch and be connected.
Step 2d, after signaling connect to be set up, all group's CAMEL-Subscription-Information that switch is corresponding with each terminal send to the base station.
All group's CAMEL-Subscription-Information corresponding to each terminal are all group's CAMEL-Subscription-Information corresponding to terminal iidentification of each terminal.
Step 2e, base station send group's CAMEL-Subscription-Information download instruction to each terminal.
Step 2f, each terminal are downloaded from the base station and all group's CAMEL-Subscription-Information that oneself adapt to according to group's CAMEL-Subscription-Information download instruction, and return to the base station to download after downloading end and complete message, finish to inform that the base station is downloaded.
Step 2g, base station send to switch and download end, finish to inform that switch is downloaded.
Switch receives when downloading end, the download sign of this terminal can be set to vacation (False), sends to identify group's CAMEL-Subscription-Information corresponding to this terminal.
Step 2h, when the next one transmission cycle arrives, the switch of core net sends PAGING message to the base station that covers terminal.As shown in Fig. 2 B, within this transmission cycle, N the PAGING message that switch sends to the base station is respectively N+1PAGING message to the 2N PAGING message.
Simultaneously, switch is selected N terminal again according to downloading sign from remaining terminal, be connected to set up signaling by the base station with this N terminal, and group's CAMEL-Subscription-Information is sent to this N terminal.
Because subsequent step is identical with above-mentioned steps 2b-step 2g, no longer repeat to give unnecessary details at this.
In this embodiment, switch is by arranging the transmission cycle, and when the transmission cycle arrives, initiate the paging flow process by the base station to terminal, further only initiate paging to the terminal of specifying number by arranging in each paging, send corresponding all group's CAMEL-Subscription-Information separately to a collection of terminal within each transmission cycle, send corresponding all group's CAMEL-Subscription-Information separately in the next one transmission cycle to another batch terminal, by setting the transmission cycle and specifying number can prevent the space interface signaling storm, also guaranteed the harmony of flow.
Above-mentioned execution mode is mainly switch and initiatively pushes the mode of group's CAMEL-Subscription-Information to terminal.In actual application, the active push mode is mainly used in terminal when just having started shooting; After the terminal card machine, switch normally just initiatively pushes group's CAMEL-Subscription-Information to terminal according to the change of group or when newly-built.And the present embodiment also allows terminal initiatively to initiate to download its corresponding all group's CAMEL-Subscription-Information, and switch is handed down to terminal according to the download request of terminal with corresponding all the group's CAMEL-Subscription-Information of this terminal.As shown in Fig. 2 C, this execution mode mainly comprises:
Step 21, terminal send group's download request to the base station, described download request comprises terminal iidentification.
Step 22, base station receive group's download request, and the group's download request that receives are transmitted to switch.
What step 21 and step 22 were described is that terminal initiatively sends the process of group's download request to switch.
Step 23, switch are according to the terminal iidentification in group's download request, and all group's CAMEL-Subscription-Information that will be corresponding with this terminal send to the base station.
Wherein, after switch receives download request, therefrom obtain the terminal iidentification of the terminal that sends download request.Then, switch from all the group CAMEL-Subscription-Information corresponding with each terminal iidentification that obtain, obtains all group CAMEL-Subscription-Information corresponding with this terminal according to this terminal iidentification, and all group's CAMEL-Subscription-Information that will be corresponding with this terminal send to the base station.
Step 24, base station send group's CAMEL-Subscription-Information download instruction to terminal.
Step 25, terminal are downloaded its corresponding all group's CAMEL-Subscription-Information according to group's CAMEL-Subscription-Information download instruction of base station from the base station, and complete message completing to send to the base station to download after downloading.
After step 26, base station reception are downloaded and completed message, send to switch and download end, download end to inform switch.
Above-mentioned steps 23-step 26 is described is the process that all group's CAMEL-Subscription-Information that switch will be corresponding with terminal send to terminal.
Further, in above-mentioned implementation process, if only there is a small amount of terminal to initiate simultaneously to download the request of corresponding all group's CAMEL-Subscription-Information, switch can respond the request of these terminals simultaneously.If being arranged, great amount of terminals initiates simultaneously to download the request of corresponding all group's CAMEL-Subscription-Information, for fear of the space interface signaling storm, switch can be according to the default transmission cycle, and only send corresponding all group's CAMEL-Subscription-Information to the terminal of specifying number in each transmission cycle, be that switch in the corresponding transmission cycle, sends to terminal with corresponding all the group's CAMEL-Subscription-Information of terminal in terminal.For switch, can preset an end-gate limit value, when the terminal quantity of the request of initiate downloading corresponding all group's CAMEL-Subscription-Information during lower than the end-gate limit value, think that a small amount of terminal initiates to download the request of corresponding all group's CAMEL-Subscription-Information simultaneously, otherwise think that great amount of terminals initiates to download the request of corresponding all group's CAMEL-Subscription-Information simultaneously.Wherein, the end-gate limit value can arrange according to actual conditions, and the present embodiment does not limit its concrete numerical value.
Further, in the present embodiment the various embodiments described above mode, the timing of transmission cycle, appointment number and buffering timer allows tracing section updating flow process (TA), base station or the whole network configurable, to guarantee the dynamically flexibility of restructuring.
In the present embodiment, switch is set the cache-time of group's CAMEL-Subscription-Information, group's CAMEL-Subscription-Information is cached within a certain period of time, prevent same group CAMEL-Subscription-Information from constantly repeating received and cause and repeat to send to terminal problem, having reduced to a certain extent the probability that causes mouthful empty signaling storm.Further, the present embodiment sends to appointment several terminals by the transmission cycle being set and specifying in each transmission cycle, has realized that the timesharing in batches of group's CAMEL-Subscription-Information sends, and has further reduced the probability that the space interface signaling storm occurs.And the configurable flexibility that guarantees dynamic regrouping process of cache-time, transmission cycle and appointment number.
