Wherein more preferably, at the end of the group calling in described group calling list, described server is to the mobile terminal transmitting group calling release notice having neither part nor lot in described group calling;
Described mobile terminal receives described group calling release notice, and is deleted by call information corresponding in described group calling list.
The invention solves after mobile terminal exits current group calling, the problem of group-calling service relevant to oneself cannot be known.By method provided by the present invention, even if mobile terminal can not participate in all relative group callings, but can by automatic clawback mode after exiting current group calling, and add current and group calling that priority the highest relevant to oneself.Present invention effectively prevents because missing instruction or information and the security risk caused, having the safety being easy to railway transport field, also improving the operating efficiency of mobile terminal user simultaneously.
Accompanying drawing explanation
Fig. 1 is in the present invention, and mobile terminal receives the processing procedure of group calling.
Embodiment
Below in conjunction with the drawings and specific embodiments, technology contents of the present invention is described in detail.
The automatic clawback of realization provided by the present invention adds the method for group calling by setting group calling list, the call information failing to participate in time group calling can be added in group calling list.After mobile terminal completes active calls, from group calling list, obtain the group calling that class of call is higher.Again according to call information from trend POC server clawback, send and add group calling request, continue to participate in oneself other relevant group-calling service.In the present invention, each mobile terminal one configuration group calling list.This group calling list is for storing relevant to mobile terminal and not participating in the call information of group calling in time.Comprising the information such as class of call, call reference number.Introduce specific embodiment of the invention process below.
First, the process of the multiple group calling request of mobile terminal process is introduced.
When having multiple group calling request when mobile terminal is idle, according to the call treatment that class of call selects priority level higher.And when mobile terminal is in group calling, and when having other group calling requests, need the class of call judging current group calling and other group callings, determine that exiting active calls still continues active calls, concrete deterministic process can see Fig. 1.
Whether mobile terminal has new group calling B to ask to add, judge current in group calling A: if, then need the class of call judging group calling A and group calling B; If not in group calling A, then join group calling B.When mobile terminal judges the class of call of group calling A and B, if group calling B be superior to group calling A, so exit group calling A and the call information of group calling A be added in group calling list, joining group calling B simultaneously.After group calling B terminates, mobile terminal then can continue to participate in group calling A.If the class of call of group calling B not higher than the class of call of calling A, is then refused group calling B, and the call information of group calling B is saved in group calling list.After waiting for that current group calling A terminates, continue to participate in group calling B.Add fashionable for multiple group calling request, then repeat above-mentioned deterministic process, and fail the calling of the multiple group callings participated in time and be saved in group calling list.
Secondly, the disposition of mobile terminal for call information in group calling list is introduced.
When mobile terminal is in current group calling, a certain group calling in group calling list may discharge.
The call information failing to participate in all group callings is saved in group calling list.When wherein a certain group calling discharges, mobile terminal is without the need to participating in corresponding group calling in continuation.In order to avoid subsequent movement terminal continues this group calling of clawback, then in group calling dispose procedure, delete respective call information by POC server proactive notification mobile terminal.After initiating group calling in POC server, the mobile terminal failing to participate in this group calling automatically detected.Group calling object then have recorded the information of corresponding mobile terminal.When POC server terminates a certain group calling, obtain the user number information of the mobile terminal of group calling object record, and to corresponding mobile terminal transmitting group calling release notice.Mobile terminal judges whether the call information of this group calling is kept in group calling list after receiving POC server group calling release notice.If, then directly delete this call information; If no, then ignore and this time discharge notice.
After mobile terminal terminates current group calling, then continue the group calling participating in failing to process in time according to the call information of group calling list records.
Mobile terminal finds out the highest group calling of class of call from group calling list, and according to the call reference number of group calling to POC server clawback, sends and add call request.And during for the group calling that class of call is identical, mobile terminal can be selected arbitrarily one of them group calling clawback and add.If the group calling of mobile terminal clawback has not been present in POC server, POC server can send to mobile terminal the feedback message refusing to add.Mobile terminal receives refusal feedback message, and is deleted from group calling list by the call information of clawback group calling, again processes other group callings in group calling list.If the group calling of clawback is still present in POC server, POC server sends the message accepting to add group calling to terminal.After standby communication terminal adds, the call information of this group calling is deleted from group calling list.After mobile terminal processes certain call information in group calling list, group calling success or not all can delete this information automatically.
In sum, the invention solves after mobile terminal exits current group calling, the problem of group-calling service relevant to oneself cannot be known.Even if mobile terminal can not participate in all relative group callings, but can by automatic clawback mode after exiting current group calling, and add current and group calling that priority the highest relevant to oneself.Therefore present invention effectively prevents the security risk caused because missing some group calling, having the safety being easy to railway transport field, also improving the operating efficiency of mobile terminal user simultaneously.
Above the method that the automatic clawback of realization provided by the present invention adds group calling is described in detail.For one of ordinary skill in the art, to any apparent change that it does under the prerequisite not deviating from connotation of the present invention, all by formation to infringement of patent right of the present invention, corresponding legal liabilities will be born.
