Description
Technical field
The present invention relates to digital cluster system, terminal independently realizes the method that cross-dispatching client switches in particularly a kind of CDMA standard Digital Clustering.
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 (the Global System forMobile Communications at existing GSM 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.
The Digital Clustering of realizing based on the CDMA2000 technology mainly contains two kinds by channel resource allocation mode branch at present:
A kind of is the enhanced group calling:
Application number is the control method that discloses a kind of CDMA2000 digital cluster system calling procedure in the Chinese patent application of CN200410027538, and its calling procedure comprises: (1) terminal sends call setup request message, requires to activate group; (2) system handles the setup requests of terminal; (3) group enters talking state, and promptly group activates, and perhaps access success is set up, and the terminal of successful paging this moment can be applied for right to speak; (4) demanding terminal finishes conversation, sends the end of conversation request, requires system to discharge all resources of this calling, and putting group is non-activation; (5) system handles the end of conversation request.
This method is when carrying out trunked call, for each cluster user terminal is distributed air traffic channel separately, user terminal is by the paging mode by existing CDMA2000 1X normal voice calls, promptly press IMSI (International Mobile Subscriber Identity, international travelling carriage identification code) paging goes into to call out, and what be that the terminal distribution channel also adopts when terminal insert to be called out is the channel allocation mode of normal voice calls, this like this trunked call even can break through geological restraint to realize roaming in the mode of independent allocated channel, show differently, be referred to as the enhanced group calling in the literary composition with existing professional trunked call;
Another kind is a traditional group call:
Publication number is a kind of trunking communication method that discloses the CDMA2000 mobile communcations system in the PCT international application of WO2004/110085A1, by base station system is public forward traffic channel of same group allocation under same sub-district, group's terminal uses public Long Code Mask to monitor public forward traffic channel, is oppositely adopting a shared channel to provide the reverse traffic support by the mode of scheduling for group's terminal.It is to set up forward direction and reversed shared channel between terminal and the base station that this patent emphasis has been illustrated in wireless side, and the capture terminal forward shared channel inserts the mode of calling out.Because performance when this kind means of communication are used (as: group calling of certain region a large number of users etc.) is similar with existing professional cluster and for being different from the enhanced group calling mode that has the CDMA mode cluster system now, in the literary composition method of calling of the present invention is called traditional group call;
China Patent No. is CN200410027639, denomination of invention has realized the direct-cut operation function for the patent of invention of " realizing the method for direct-cut operation in the code division multiple access mode cluster system " on the enhanced call basis in existing CDMA Digital Clustering, mainly refer to the cross-dispatching client direct-cut operation, the described mode of this patent only is fit to the enhanced group calling, but be not suitable for the switching under the traditional type Channel Sharing situation, because:
This mode belongs to direct-cut operation, and terminal is inevitable to need system side (comprising base station side and network side) to participate in when each the switching, and the resource that will occupy alternately of signaling causes system loading;
When the cross-dispatching client direct-cut operation, cause voice quality problem owing to reliability and success rate;
This in addition switching mode also needs the equipment of non-group system---and it is that channel is monopolized in the terminal foundation that switches that mobile switching centre participates in Target cell.
China Patent No. is CN200310100481, denomination of invention has proposed the autonomous switching of the same group calling forward shared channel between different cellular cells of the terminal under the service condition in trunked call for the patent of invention of " being in the method for the colony terminal switching that receives service condition ", this mode has been considered the situation of shared channel, but it has the following disadvantages:
Its handover triggering condition is the threshold value that signal strength signal intensity reaches cell-of-origin and Target cell, if but the jitter of eating dishes without rice or wine like this may cause terminal frequently to be switched;
Describe this terminal according to it and after reaching signal strength threshold, also will obtain the current group number of paging channel broadcasting and the forward shared channel information of this cluster group, and terminal can't be obtained paging channel information in business state in CDMA technology, and promptly this method is not suitable for the CDMA digital cluster system;
This patent hypothetical target side has shared channel resources, do not consider that target side do not have the situation of channel resource, and in actual call is set up, there is not the user if judge this zone, improve utilization rate of air interface resource in order to save interface-free resources, will discharge the resource of this calling, this patent just can't be finished and switch like this;
At last, this patent has only considered that switching influences the influence of but not considering dispatching client to eating dishes without rice or wine.
The patent No. is WO03055245A1, denomination of invention realizes the thought that cross base station controller (BSC) switches for " BASE INITIATED CDMA SOFTHANDOFF FOR GROUP CALL " proposed colony terminal in calling, wherein end objectives local resource information will be notified by target cell base station, and will be terminal distribution exclusive resource (an individual inbound link), but it is not suitable for the needs of traditional group call in the CDMA Digital Clustering at present, at first the CDMA Digital Clustering has developed into the mode that shared channel is set up resource, secondly neighboring BS information changes, relative, by its described method, information notice terminals again that these are different when each switching takes place can expend system resource and time.
