The group information updating method of number cancelling mobile terminal of the present invention, whether number cancelling mobile terminal is had by regular check, when being checked through number cancelling mobile terminal, trigger the group information updating to number cancelling mobile terminal, and carry information signals base controller does not need with mobile switching centre authentication mutual in the paging, when removing already present group identification after paging to number cancelling mobile terminal, after this number cancelling mobile terminal just cannot respond paging, thus reduces the probability of by mistake exhaling.
Fig. 5 is the flow chart of the another kind of embodiment of group information updating method of number cancelling mobile terminal of the present invention.
Step S501, dispatching home location register 42 pairs of mobile terminals 10 carry out cancellation operation, and are labeled as by number cancelling mobile terminal in cluster user database 43 and need to carry out group information updating.
Step S502, dispatching control center 41 timing sends request to dispatching home location register 42, to inquire about the information of number cancelling mobile terminal.In the present embodiment, in order to realize regular check, checking module 410 can according to the time interval of the synchro timer configuration in trunking dispatching subsystem 40, and dispatching control center 41 asks the information of number cancelling mobile terminal to dispatching home location register 42.This time interval can be set to fixing duration, also can arrange certain duration scope for configuration.
Step S503, after dispatching home location register 42 receives request, inquires about the information of number cancelling mobile terminal, and returns response to dispatching control center 41 from cluster user database 43.This response carries the information of number cancelling mobile terminal, and the information of this number cancelling mobile terminal at least comprises the positional information of number cancelling mobile terminal, certainly can also comprise international mobile subscriber identity or Electronic Serial Number.
Step S504, after dispatching control center 41 receives response, sends paging to base station controller 22.In this paging, carry information does not carry out authentication alternately to indicate base station controller 22 with mobile switching centre 31, and direct paging number cancelling mobile terminal.
Step S505, base station controller 22 pairs of number cancelling mobile terminals carry out paging.In the present embodiment, base station controller 22 is the positional information paging number cancelling mobile terminals by number cancelling mobile terminal.In addition base station controller 22 can also with the mode paging number cancelling mobile terminal of region-wide paging.Cannot accurately paging to be to number cancelling mobile terminal to avoid the positional information of the number cancelling mobile terminal owing to storing in cluster user database 43 inaccurate, region-wide paging refers to all band of position paging cancellation users in base station controller 22 pairs of coverages.
Step S506, the paging of number cancelling mobile terminal response base station controller 22.
Step S507, after dispatching control center 41 upgrades the group information on number cancelling mobile terminal, sends to dispatching home location register 42 and upgrades result, represents the group information updating success of number cancelling mobile terminal.
Step S508, the cancellation user in cluster user database 43 is labeled as and does not need to carry out group information updating after receiving and upgrading result by dispatching home location register 42.
Step S509, dispatching control center 41 discharges number cancelling mobile terminal.
The group information updating method of number cancelling mobile terminal of the present invention, whether number cancelling mobile terminal is had by regular check, when being checked through number cancelling mobile terminal, trigger the group information updating to number cancelling mobile terminal, and carry information signals base controller does not need with mobile switching centre authentication mutual in the paging, when removing already present group identification after paging to number cancelling mobile terminal, after this number cancelling mobile terminal just cannot respond paging, thus reduces the probability of by mistake exhaling.In addition, also by the mode of region-wide paging to avoid the positional information of the number cancelling mobile terminal owing to storing in cluster user database inaccurate cannot accurately paging to number cancelling mobile terminal.
These are only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
