Description of the drawings
Fig. 1 is the processing procedure that mobile terminal reception group is exhaled in the present invention.
Specific implementation mode
The technology contents of the present invention are described in detail in the following with reference to the drawings and specific embodiments.
The method provided by the present invention for realizing that automatic clawback addition group is exhaled exhales list by setting group, can will fail and
When the call information addition group exhaled of participation group exhale in list.After mobile terminal completes active calls, exhales in list and obtain from group
Higher group of class of call is exhaled.Further according to call information from trend POC server clawback, sends addition group and call for asking, continue to join
With with oneself other relevant group-calling service.In the present invention, one configuration group of each mobile terminal exhales list.The group exhales list
It is related to mobile terminal and without participation group is exhaled in time call information for storing.Including class of call, call reference
The information such as number.The specific implementation process of the present invention is described below.
First, it introduces mobile terminal and handles the multiple groups of processes for calling for asking.
There are multiple groups when the mobile terminal free time when calling for asking, the higher calling of priority level is selected according to class of call
Processing.And when mobile terminal is in during group exhales, and there are other groups to call for asking, need to judge to exhale for current group to exhale with other groups
Class of call, decision exits active calls and is also to continue with active calls, and specific deterministic process may refer to Fig. 1.
Whether mobile terminal has new group to exhale B request additions, judge current in group exhales A：If needing judgement group
A and group is exhaled to exhale the class of call of B；If not in group exhales A, it is added to group and exhales B.When mobile terminal judgement group exhales exhaling for A and B
When being rank, if group exhales the group that is superior to of B to exhale A, exits group and exhale A and exhale the call information of A to be added to group group and exhale
In list, while being added to group and exhaling B.After group exhales B, mobile terminal can then continue to participate in group and exhale A.If group exhales B's
For class of call not higher than the class of call of calling A, then refusal group exhales B, and exhales the call information of B to be saved in group group and exhale list
In.Wait for current group exhale A after, continue to participate in group and exhale B.When calling for asking addition for multiple groups, then repeat above-mentioned to judge
Journey, the multiple groups of callings exhaled for failing to participate in time, which are preserved to group, exhales in list.
Secondly, the disposition that mobile terminal exhales group call information in list is introduced.
When mobile terminal in exhale for current group when, group exhales a certain group in list to exhale and may discharge.
Group, which exhales to save in list, fails to participate in all groups of call informations exhaled.It exhales and has discharged when wherein a certain group
When, mobile terminal is without exhaling continuing to participate in respective sets.In order to avoid subsequent movement terminal continuation clawback, the group is exhaled, then is existed
During group exhales release, respective call information is deleted by POC server proactive notification mobile terminal.Initiation group in POC server
After exhaling, automatically detects and fail to participate in the mobile terminal that the group is exhaled.Group exhales object then to have recorded the information of corresponding mobile terminal.When
POC server terminates a certain group when exhaling, and acquisition group exhales the user number information of the mobile terminal of object record, and is moved to corresponding
Dynamic terminal transmission group exhales release to notify.After mobile terminal reception POC server group exhales release to notify, the calling letter that the group is exhaled is judged
Whether breath, which is stored in group, is exhaled in list.If directly deleting this call information；It is this time discharged if it is not, ignoring
Notice.
After mobile terminal, which terminates current group, exhales, then exhales the call information of list records to continue to participate according to group and fail in time
The group of processing is exhaled.
Mobile terminal is exhaled from group finds out highest group of call reference number exhaled, and exhaled according to group of class of call in list
To POC server clawback, sends and call request is added.And when being exhaled for identical group of class of call, mobile terminal can be arbitrary
One of group is selected to exhale clawback and be added.If the group of mobile terminal clawback is exhaled not already present in POC server, POC
Server can send the feedback message that refusal is added to mobile terminal.Mobile terminal receives refusal feedback message, and by clawback group
The call information exhaled, which is exhaled from group in list, to be deleted, and processing group exhales other groups in list to exhale again.It is still deposited if the group of clawback is exhaled
It is in POC server, POC server sends the message for receiving addition group and exhaling to terminal.After standby communication terminal is added, by the group
The call information exhaled, which is exhaled from group in list, to be deleted.After mobile terminal has handled certain call information that group is exhaled in list, no matter group
Exhale success or not that can all be automatically deleted this information.
In conclusion the present invention solve mobile terminal exit current group exhale after, can not know and exhale industry with oneself relevant group
The problem of business.Exhaled even if mobile terminal cannot participate in all relative groups, but exit current group exhale after can be by automatic
Clawback mode, and currently group related and highest priority to oneself is added and exhales.Therefore present invention effectively prevents because missing certain
A little groups exhale the security risk of initiation, have the safety for being easy to railway transport field, while also improving the work of mobile terminal user
Make efficiency.
