Embodiment
In order to solve the problems of the technologies described above, the invention provides a kind of call-establishing method that is used for digital cluster system.This method may further comprise the steps:
A) work the person of exhaling and select a group to make a call, work exhale that terminal sends rise to call for to ask through base station sub-system and send to network side, this is called for to ask and carries user position information.
B) dispatching home location register is carried out authentication to this terminal, and authenticating result is notified to dispatch server.When dispatch server receives authentication responses, judged and exhaled the user position outside the group scheduling district, and group restricted type is not strict limited, sends group calling paging request to working zone (sub-district or scheduling district) and all base station controllers of group scheduling service area of exhaling the terminal place.
C) after base station controller is received the paging request, notify its following all transceivers to set up corresponding forward traffic channel and reverse traffic channel, and the cluster data link is shared in the special use between foundation and the dispatch server.
D) base station controller is set up successfully back notice dispatch server at wireless channel, and send beep-page message rising on the paging channel exhale zone and group scheduling district, the terminal that belongs to this group is the upright Traffic Channel of this establishment according to the information capture in the beep-page message, in the access group calling.
E) after message was finished in the foundation of dispatch server As-received station control transmission, the call setup success entered talking state.After group call was set up, the scheduling district of group comprised the zone that all set up call resources.
F) when the terminal in the conversation is left the dispatcher-controlled territory of limited group, terminal sends handoff request to base station controller, base station controller is set up the wireless communication resource according to the method for calling and the constrained type of group, base station controller sends handover acknowledge message to terminal, this message is carried new traffic channel information, terminal is received response message, finishes Traffic Channel and switches.When judging according to the method for calling base station controller needs dispatch server of group whether the user can step out the scheduling district, base station controller sends user's handoff completion message to dispatch server.After dispatch server was received handoff completion message, when judging that this group user can be stepped out the scheduling district, dispatch server was not responded and is answered, and gives tacit consent to this user's switching and finishes.When judging that this group user cannot be stepped out the scheduling district, send the operation information of removing this customer call to base station controller, base station controller is received tear down message, sends to the user and withdraws from call command, removes this user's wireless communication resource simultaneously.
Wherein, the method for calling of group comprises: press group identification and set up the user ID foundation calling of calling out and pressing each user in the group.The constrained type of group comprises: strict limited group, and the outer PoC (Push To Talk is called for short PTT) of not supporting in scheduling district is called out; Limited group, outer the rising in scheduling district exhaled the talking connection that goes out the scheduling district with call terminal.
Wherein, press the calling that group identification is set up, base station controller is directly preserved the constrained type of call group; By the calling that the user ID of each user in the group is set up, preserve the constrained type of call group by dispatch server.When the user goes up switching message, base station controller judges that this calling is the calling of setting up according to group identification, check the local call group constrained type of preserving of base station controller, when group is not strict limited (strictness is limited can not to go out the scheduling district fully), base station controller is set up the wireless communication resource of group, send handover acknowledge message to the user then, the user switches under the new zone.When the user goes up switching message, base station controller judges that this calling is when setting up calling by each user in the group, base station controller is set up the wireless communication resource of member terminal, send handover acknowledge message to the user then, the user switches under the new zone, base station controller judges according to the constrained type of call group whether the user can step out the scheduling district by dispatch server by sending handoff completion message to dispatch server.Dispatch the district when judging that this group user can be stepped out, dispatch server is not responded and is answered, and gives tacit consent to this user's switching and finishes.Dispatch the district when judging that this group user cannot be stepped out, send the operation information of removing this customer call to base station controller.
G) calling of setting up according to group identification, group's wireless communication resource of under the group scheduling zone, distributing, base station controller can obtain whether each sub-district also has excited users under this zone by the inquiry of timed sending User Status, when not having excited users, group's wireless communication resource of no excited users sub-district under this zone will be removed in the base station.Set up the user radio conversation resource of calling by each user in the group, when long-time user does not have reverse empty frame, base station controller will be removed this regional user radio resource of conversing.
Wherein, in step a) to e) in, dispatch server exhales the user outside the group scheduling district by having judged, exhales the zone to send paging by having given separately, sets up the wireless communication resource, allows exhale the user to set up group calling outside the limited group calling scheduling district.Behind the call setup, the scheduling district of group comprises the zone that all set up call resources.In step f)～g), call terminal leaves the group scheduling district, and by switching message, base station controller distributes new wireless communication resource, by judging that group restricted type chooses, allow the call terminal of limited group obtain continuing that the wireless communication resource keeps calling out.The recovery of radio channel resource is safeguarded according to the mode of calling out in the base station, removes the wireless communication resource that does not have under the excited users zone.
Below with reference to accompanying drawing, describe the specific embodiment of the present invention in detail.
Fig. 1 is the network structure of application according to the digital cluster system of the call-establishing method of the embodiment of the invention.As shown in Figure 1, this digital cluster system comprises:
Colony terminal: also abbreviating terminal as, is the terminal equipment of group services such as response of judgement, the group calling paging of the storage that can support user profile and group information, dispatcher-controlled territory.
Base station sub-system: comprise the transceiver (BTS) of supporting trunked call, base station controller (BSC) and with the mutual dispatching client (PDC) of network side.
Dispatch server: realize the calling control and the right of speech management of trunked call.
Dispatching home location register: preserve the log-on message and the positional information of cluster user and group, realize authentication, mandate and billing function, and the position is upgraded and group management function to cluster user.
Wherein, dispatch server and dispatching home location register are referred to as network side or dispatching patcher.System side has then comprised base station sub-system and dispatching patcher.
Fig. 2 is the flow chart according to the call-establishing method of the embodiment of the invention.Wherein, the reciprocal process of network side and base station side may further comprise the steps:
S202, working the person of exhaling selects group to make a call, rise and to exhale terminal to send to call for to base station sub-system to ask, the scheduling district that base station sub-system will work the person of exhaling zone correspondence attaches calling for and gives dispatch server in asking, and dispatch server has sent to dispatching home location register and exhaled authentication request.
S204, dispatching home location register has been received and has been exhaled authentication request, has handled and has exhaled authentication, sends authentication responses to dispatch server, response message is carried authentication informations such as group call mode, group restricted type, group scheduling district.
S206, after dispatch server is received the authenticating result that dispatching home location register returns, judged that the scheduling district of exhaling the user is not in the group scheduling district, when the constrained type of group is that limited group is (strict limited, dispatch server will be refused this and call out) and the method for calling of group be to set up when calling out by each user in the group, send the paging request of being with caller information to the BSC that works the person of exhaling place, to all non-called paging requests of exhaling BSC to send group member (can pack) in this group scheduling service area to the member.When the method for calling of group is to set up when calling out by group identification, send the group calling paging request of band caller information to the BSC that works the person of exhaling place, exhale BSC to send not group calling paging request to all in this group scheduling service area non-with caller information.When the method for calling of group is to set up when calling out by group identification, carry the constrained type of group in the paging request.Whole process is limited group paging.
S208, after BSC receives the group calling paging of dispatch server transmission, set up this call-specific to the dispatch server request on the one hand and share cluster data link (STDL), dispatch server has responded the STDL link setup request of exhaling BSC, sets up the special use of this calling and shares the cluster data link.
Wherein, sharing the cluster data link is the carrying that voice are transmitted in the CDMA mode cluster system, and its life cycle is identical with current calling, and just this STDL finishes just can be released in group calling.If the situation of unusual release is arranged, base station side and network side can be monitored at any time, rebuild.
On the other hand, BSC notifies its relevant down BTS (having comprised the BTS that exhales under the zone) to set up radio channel resource.When method of calling is set up calling for pressing group identification, set up forward direction and the reverse traffic channel shared, timed sending group calling beep-page message on paging channel, base station sub-system is preserved the constrained type information of group simultaneously.When method of calling was called out for setting up by each user in the group, BTS set up forward direction and reverse traffic channel to the terminal of each page response.
When method of calling is set up calling for pressing group identification, after the BTS wireless channel under the BSC is set up successfully, finish the message informing dispatch server by foundation.Group calling beep-page message on the calling and called terminal paging receiving channel, the Traffic Channel of access assignment enters talking state; When method of calling is called out for each user in by group sets up, rise and exhale user and at least one called subscriber all to accept page response, after inserting forward direction and reverse traffic channel separately, the calling and called user radio channel of group is set up successfully, finishes the message informing dispatch server by foundation.
S210, message is finished in the foundation of dispatch server As-received station control, and the call setup success enters talking state, and dispatch server notice dispatching home location register begins to charge.
By above-mentioned steps as seen, the network controls of call setup is earlier to judge that by dispatch server group restricted type accepts the outer user in scheduling district and rise and exhale, set up the wireless communication resource (foundation of resource is distinguished to some extent according to method of calling) of exhaling in zone and the group scheduling zone by base station sub-system, the user can initiate group calling and set up successfully outside the scheduling district.
Fig. 3 is the flow chart according to talking connection outside the scheduling district of the embodiment of the invention.As shown in Figure 3, the reciprocal process of network side and base station side may further comprise the steps:
S302, terminal is left scheduling district (searching stronger district pilots signal), sends handoff request by reverse traffic channel to base station sub-system, carries the cell information that will stride into.
S304, after base station sub-system is received and is switched message, when the method for calling of group is set up calling for pressing group identification, base station sub-system reads the constrained type of local call group of preserving, it is (strict when limited when group is limited group, resource is not set up in the base station, reply and switch message and carry the user and release order, the user receives and withdraws from calling), base station sub-system sets up shared wireless communication resource for new sub-district, comprise shared forward direction and reverse traffic channel, timed sending group calling beep-page message on paging channel.The base station sub-system terminal sends handover acknowledge message, carries the newly assigned traffic channel message in to be switched sub-district.Terminal is received handover acknowledge message, cuts the Traffic Channel in the new sub-district.Wireless communication resource when the group identification of under new sub-district, setting up, other group members in this new sub-district also can insert calling simultaneously, this mode of calling out by group identification foundation can move with the user, the scope of the dispatcher-controlled territory of call group can enlarge, for preventing from infinitely to stride greatly, the resource that the back has the sub-district not have excited users is handled.
Base station sub-system is received switching message, when the method for calling of group is called out for each user in by group sets up, base station sub-system is set up member's wireless communication resource in new sub-district, comprise forward direction and reverse traffic channel, the base station sub-system terminal sends handover acknowledge message, carries the newly assigned traffic channel message in to be switched sub-district.Terminal is received handover acknowledge message, cuts the Traffic Channel in the new sub-district.
S306, after base station sub-system determined that terminal is cut new sub-district, when the method for calling of group was called out for each user in by group sets up, base station sub-system sends to switch to dispatch server finished notification message.When the method for calling of group was set up calling for pressing group identification, this locality had been judged limited situation, does not send this notification message.
S308, dispatch server receive to switch and finish notification message, judge the constrained type of this group, and when group is limited group, dispatch server is not responded and answered, and default base station is finished the switching of this user terminal.When judging that this group is strict limited group, the user cannot step out the scheduling district, sends the operation information of removing this customer call to base station sub-system, discharges this user's unlimited conversation resource.
S310, base station sub-system is during to the calling of setting up according to group identification, can be in the scheduling district of call group regularly sends user status query message in the shared forward traffic channel of sub-district.User under the dispatcher-controlled territory receives the User Status inquiry, replys in reverse traffic channel status poll last time, informs that base station sub-system has excited users to exist.When base station sub-system sends User Status inquiry no response, judge the following no excited users in certain sub-district in this zone, then discharge group's wireless communication resource of certain sub-district.
When base station sub-system was set up calling by each user in the group, the member terminal under call group scheduling district did not have under the situation of reverse empty frame in the given time, and this user radio conversation resource in this zone will be removed in the base station.This process is the inner determination flow of base station sub-system, and does not have Signalling exchange between the terminal.
By above-mentioned steps as seen, when the user of limited group leaves the scheduling district, by switching the message informing base station sub-system, base station sub-system is according to the difference of group call mode, judge that the user can step out the scheduling district of group, set up the conversation resource to the user, user terminal switches to this zone, finishes continuing of conversation.
In sum, the present invention proposes a kind of call-establishing method in the digital cluster system of realizing based on the CDMA2000 technology, this method is suitable for the calling control of limited group outside the scheduling district, solve the circumscribed problem of user moving range in the limited group, met growing trunking communication demand.
The above is embodiments of the invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within the claim scope of the present invention.
