Abstract
The invention relates to a method for separating and interpolating the CDMA digit group system and distribution area, wherein when the terminal M is used, obtains present DLA information from system; POS separates the terminal M at Call_1 and interpolates Call_2, to send separate information to the terminal M with DSA information of Call_2; terminal M receives said information, judges if its DL is in the DSA of Call_2, if it is, moves back from the Call_1 and responds allow message to the PDS; the distributing server receives message and sends page message of Call_2 to the terminal M; terminal M receives Call_2, separates and interpolates successfully; if the terminal's DLA is not in the DSA of Call_2, it sends reject message to the PDS, the distributing server will not send page message. The invention can avoid failed interpolation when the separation is successful.
Description
Technical field
The present invention relates to moving communicating field, relate in particular in digital cluster system forced releasing and forced interposing control user terminal.
Background technology
Mobile communication technology has developed into the third generation, and wherein trunking communication becomes a kind of indispensable communication traffic day by day.Trunking communication is meant a kind of dispatching communication mode of special use, comprises special-purpose commander and dispatching communication, and in use cluster user can add calling simultaneously, and conversation is carried out with single worker or half-duplex mode.
Trunking communication has been experienced simple intercom system to single base station mini system, arrive the development course of big capacity multizone system again, after experienced again from the simulation cluster to the leap of Digital Clustering, make trunking communication all can adopt more reliable digital processing mode at the aspects such as multi-access mode, speech coding, modulation-demodulation technique, simultaneous techniques, error-detection error-correction and diversity technique of signalling coding, employing.Two kinds of digital cluster systems of extensive use at present are based on TDMA (Time Division Multiple Access, time division multiple access) iDEN of technology (integrated Digital Enhanced Network, Integrated Digital Enhanced Network) and TETRA (Terrestrial Trunked Radio, land trunked radio), these system applies all belong to special-purpose cluster in specific department and unit, for promoting the sizable application of digital cluster system, further boost the efficiency of frequency resources utilization simultaneously, trunked communication system a new application trend occurred on using, the unification that exactly a plurality of digital cluster systems combined is used and is managed, thereby be able to share channel and channel, share the overlay area, communication service, carry on a shoulder pole the purpose of expense altogether, cluster application realizes the common network operation from developing into towards indivedual professional users towards a plurality of group users the most at last.
Trunking communication has promoted existing GSM (Global System forMobile Communications by private network to the development of common network, global system for mobile communications), realize the research of Clustering on CDMA (Code Division MultipleAccess, the code division multiple access) network.
Call out in group system and be limited in certain territorial scope usually, if colony terminal (also abbreviating terminal in the literary composition as) exceeds this limited field, system will not provide trunked call service, and this limited field is called dispatcher-controlled territory.Can be according to the actual needs of the network planning, the overlay network of system is divided into some dispatch location area (DLA, Dispatch Location Area), dispatch location area can be whole network, it also can be the part of network, with the cellular cell in the wireless communication field is least unit, the designated dispatch service of trunked call zone (DSA, Dispatch Service Area), the dispatch service zone is the set (see figure 1) of dispatch location area, when trunked call exceeded the dispatch service zone of system's appointment, system no longer provided service for it.Dispatch service zone/dispatch location area of the present invention/sub-district schematic diagram such as Fig. 1 is described as follows:
Cellular cell 101: be called for short the sub-district, the unit area that signal covers in the radio communication is as example Cell_1 to Cell_7;

Above-mentioned base station sub-system BSS, dispatch server PDS and dispatching home location register PHR are referred to as system side.
In the CDMA digital cluster system, two kinds of different resource allocation mode are arranged, the dispatch server under a kind of pattern can be realized the control to terminal.Another kind then can only control to base station sub-system, does not preserve the present residing dispatch location area of terminal (DLA) information under the system side normal condition.The inventive method all can be suitable for these two kinds of patterns.
The flow process of the limited calling forced releasing and forced interposing in present embodiment scheduling district may further comprise the steps as shown in Figure 3:
Terminal is got its present place DLA information from system side reed generally is when carrying out location registers, notifies terminal by system side in response message.Switch if stride DLA under talking state, system side can be informed the change of its present dispatch location area of terminal by handover acknowledge message, perhaps, and by the forward traffic channel periodic broadcast DLA information of sharing, by the current DLA value of terminal.It should be noted that the present invention is not limited to obtain DLA information by above mode.
Under the situation shown in Figure 1, terminal MS _ 1 its current DLA value DLA_1 of storage, terminal MS _ 2 its current DLA value DLA_3 of storage.
In another embodiment, also can be that the dispatcher directly sends the forced interposing and forced releasing instruction to dispatch server by dispatching desk, as long as this dispatcher's identity is legal, just may carry out the forced interposing and forced releasing operation.
Processing in the time of can not tolling breakdown is not a discussion scope of the present invention.
This beep-page message can be sent out repeatedly, also can send out once, under situation about sending out once, if terminal M confiscates this time message, also can insert by the beep-page message that receives the calling Call_2 that the base station periodically sends.
After step 190, dispatch server are received and disagreed with the response message of being tolled breakdown, no longer send the beep-page message of calling out Call_2 to terminal M, flow process finishes.
Cooperate Fig. 1 that an application example is described below.
Terminal MS _ 1 and MS_2 are in respectively and call out among the Call_1, and MS_1 is in dispatch location area DLA_1, and MS_2 is in dispatch location area DLA_3; At this moment, another user Call_2 that makes a call, terminal MS _ 1 and MS_2 belong to the group of this calling, the dispatch service zone of Call_2 is DSA_1, and it is urgent call that Call_2 is called out in supposition, and calling Call_1 is ordinary call, and the priority of calling out Call_2 is higher than calls out Call_1;
Dispatching control center is received the request of calling out Call_2 and is learnt terminal MS _ 1 that its request adds and MS_2 in current calling Call_1 the time, condition judgment should be tolled breakdown terminal M from call out Call_1 and intrusion goes into to call out Call_2 according to tolling breakdown, then send and toll breakdown notice, comprise the group information of calling out Call_2 and the information of dispatch service region D SA_1 to MS_1 and MS_2;
After MS_1 has received and tolled breakdown notice, judge its present place DLA_1 and belong to the dispatch service region D SA_1 that calls out Call_2, then return the response message that agreement is tolled breakdown, and withdraw from and call out Call_1 to dispatch server; Dispatch server sends the beep-page message of calling out Call_2 by BSS in its limited range DSA_1, the paging of terminal MS _ 1 response Call_2 inserts Call_2, to the forced releasing and forced interposing success of MS_1.
After MS_2 has received and has tolled breakdown notice, judge its present place DLA_3 and do not belong to the dispatch service region D SA_1 that calls out Call_2, then return and disagree with the response message of being tolled breakdown to dispatch server, and organized the information that Call_2 called out in interface display, after dispatch server receives that MS_2 disagrees with the response message of being tolled breakdown, no longer carry out the intrusion operation.
In sum, the invention provides and a kind ofly in the CDMA2000 Digital Clustering, initiatively participate in tolling breakdown flow process and carry out careful tolling breakdown by terminal, avoid dispatching that the district is limited contingently when calling out tolls breakdown success and the method for the unsuccessful situation of intrusion, satisfied group user carries out forced releasing and forced interposing control according to the priority policy of formulating in advance in the scheduling district that group administers to user terminal in this group needs.
The present invention can also have various conversion on the basis of the foregoing description, these conversion should belong to protection scope of the present invention.
For example: in another embodiment, terminal receive dispatch server toll breakdown the notice or position enquiring message after, can start a waiting timer, because the response message that terminal is returned may be lost because of the signaling collision, if dispatch server is not also received response message at timer then, can directly carry out intrusion, by new call page terminal, in order to avoid miss important call.
