Description
Technical field
The present invention relates to the group-calling service technical field, particularly a kind of group call region information determines and method of adjustment.
Background technology
Group-calling service is a kind of call business that allows group user to be established to one group of user of a certain given area and a certain group of ID.Wherein, group ID is used for the different group of sign, and the given area is commonly referred to group call region, comprises the cluster residential quarter, is used for limiting the call coverage of group calling.
Corresponding relation between the ID of preservation group in advance of system and the group call region information, described group call region information generally include the sign of each residential quarter in the group call region and the sign of the base station under the difference of each residential quarter.When certain group user is initiated group calling, system finds corresponding group call region information according to the group ID of this group user correspondence, and each base station in the notice group calling area information is that subordinate residential quarter (appearing at the residential quarter in the group call region information) allocation of downlink is shared Radio Resource, and broadcasting group calling notification message, each group user is described according to the downlink radio resource of carrying in the group calling notification message that receives and is added group calling, finish group call establishment process, the descending shared Radio Resource that distributes can be maintained to this group calling to be finished.
In the prior art, can carry out statistical analysis by the conventional scope of activities to each group user in a certain group, for group determines a fixing group call region, and in system the group call region information of the determined group call region of human configuration; When the scope of activities of this group changes, the group call region information that disposes before revising by manual operation again.
But there is certain limitation in actual applications in this mode, namely is only applicable to the situation that the group user distribution is concentrated relatively and scope of activities is relatively fixing.If the scope of activities of group user is big and often change, such as, group user is stochastic activity in the entire city scope in certain city, so then need entire city is defined as group call region, and correspondingly dispose group call region information, in actual applications, when group calling is set up, group user may just be distributed in certain interior several residential quarter of entire city scope, and system needs to be the descending shared Radio Resource of each cell allocation in the entire city scope, and this can cause the serious waste of system resource undoubtedly.
In view of the above problems, proposing again in the prior art to be that a group sets a plurality of group call regions according to different application scenarioss, correspondingly, disposes multiple group call region information; Group user can be according to the selected group call region of current application scenarios, when application scenarios changes, group user is changed group call region by mode reporting systems such as note or voice, is about to the group call region that previous selected group call region is replaced by current application scene correspondence.This mode is applicable under the situation that group user is relatively concentrated and the variation of scope of activities is relatively determined more, such as, group user according to the different distributions of executing the task in different zones.
Though this mode can reduce to a certain extent to resource waste, but this mode needs group user proactive notification system conversion group call region, and need all group user before group call region is changed, all to transfer in the new group call region, the user who not only influences group user to a certain extent experiences, and the scope of activities of group user limited have relatively high expectations, for the user has brought inconvenience.
For this reason, propose again in the prior art, can dynamically adjust group call region information, specifically, system can generate group call region information according to the positional information that each group user reports, follow-up, each group user can initiatively report the positional information after self changing, and perhaps, system is paging group user initiatively also, require it to report current position information, a kind of mode before adopting usually; System compares the positional information in the positional information that receives and the group call region information of preserving in advance, if change, then utilizes the group call region information of preserving before the updating location information that receives, thereby reaches the purpose of dynamic adjustment.
The waste system resource of having mentioned before this mode has solved and influence problem such as user experience, and have stronger real-time and flexibility, but also brought new problem: such as, based on time-division Long Term Evolution (TD-LTE, Time Division-Long Term Evolution) in the wideband digital trunked communication system of technology, for the group user that is in connection status, when its positional information changes, can initiatively report system, and for the group user that is in idle condition, when it moves in the minizone, be position information when changing, can initiatively do not report usually, have only when periodically updating timer expiry, just can initiate position updating process, report current position information.That is to say, variation has taken place in positional information that might group user, but because it does not report, so system does not also know, like this, if after the positional information of group user changes, but also do not initiate position updating process (periodically updating timer expiry) before, a certain group user has been initiated group calling, the group call region information that will preserve according to self of system is the descending shared Radio Resource of each cell allocation so, like this, the residential quarter that is in the current place of group user of idle condition may not have allocation of downlink to share Radio Resource, thereby the group user that causes being in idle condition can't receive broadcasting group calling notification message, and then can't join in the group calling.
