Abstract

A realization method based on location routing in digital cluster calling divides scheduling region in the covering area of network according to need; subordinated dispatchers of dispatching station can be divided according to jurisdiction position region, corresponding relations between dispatching station/dispatcher/position region can be established and the corresponding relations can be stored in PHR; when a terminal calls the dispatching station, PHR (scheduling attribution register) analyzes that the called party is the scheduling station, then PDS sends the instruction of paging the called scheduling station to DAS after authentication passes, and the paging instruction carries position information of the calling party; the scheduling station chooses particular dispatcher to complete the call. The invention guides the call to the nearest dispatcher and a plurality of dispatchers share a unified dispatching station number, which can facilitate resource deployment and deal with calling issue.

Description

The implementation method of position-based route in a kind of digital cluster call

Technical field

The present invention relates to the digital cluster communication field, be specifically related to colony terminal call scheduling platform technology.

Background technology

Mobile communication technology has developed into the third generation, and wherein trunking communication also 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 with simplex mode work.In broad terms, comprise that the various wireless communication systems with dispatching communication function of wireless intercom system all can include the category of trunked communication system in.

Trunking communication has been experienced simple intercom system (intercommunication form one to one) to single base station mini system (joining common-frequency simplex network construction form, alien frequencies list (two) worker network construction form, the single channel form of getting ready to go into action in hundreds, band selective call form, the multichannel form that dials automatically), arrive the development course of big capacity multizone system (the multichannel user shares form) again, after experienced again from the simulation cluster to the leap of Digital Clustering, this leap makes trunking communication at signalling coding, the multi-access mode that adopts, speech coding, modulation-demodulation technique, simultaneous techniques, aspect such as error-detection error-correction and diversity technique all can adopt more reliable digital processing mode.Two kinds of digital cluster systems of extensive use at present are based on the iDEN (integrated Digital Enhanced Network) and the TETRA (Terrestrial Trunked Radio) of TDMA multiple access technology, in order to promote 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 been promoted to go up the research that realizes Clustering at existing public network (GSM, CDMA) by the development of private network to common network.

During colony terminal call scheduling platform in the digital cluster communication field, when cluster user was dialed special number (generally being dispatching desk number or call treatment center), system determined the route of destination address according to the positional information at calling subscriber place.For example, the dispatcher of different regions shares same dispatching desk number, scheduling authority between each dispatcher is divided according to the band of position, during the customer call dispatching desk, system selects corresponding dispatcher to insert nearby according to zone, caller position, to make things convenient for allocate resource, improve call handling capacity.

During existing colony terminal call scheduling platform, generally carry out route according to terminal position district, cellular cell or region longitude and latitude, restriction can incoming call or the user list of exhalation.Relevant patent such as US6724882, CN03157508 and CN03148343 etc.These patents have a common characteristic, all be to judge in the MSC side, the mapping relations of setting up between lane place and the number screening catalogue realize, with CN03157508 is example, it has introduced a kind of in wireless dispatch system, locate in GMSC (gateway mobile switching center)/visit ground mobile switching centre (GMSC/VMSC), set up between dispatcher's termination number and area distribution MSC/VLR number and its dispatcher-controlled territory and be distributed in corresponding relation between the cell id of this VMSC, when the dispatcher makes a call, arbitrate herein, to realize the method for dispatcher's call blocking.

Prior art generally needs the cooperation of Positioning System (GPS), mobile switching centre (MSC) or packet-switched services node (PDSN), sets up local path and the corresponding relation that transmits ground area code (LATA).

Summary of the invention

The technical problem to be solved in the present invention is at the problem that prior art exists, to propose a kind of group system in-house facility that relies on and can realize the method for colony terminal calling at the dispatching desk of zones of different.

The present invention includes following steps:

1.1 in network coverage, divide dispatcher-controlled territory (sub-district, area or deployment position district) as required;

1.2 dispatching desk subordinate's dispatcher is divided according to the administration band of position, sets up the corresponding relation between dispatching desk/dispatcher/band of position, and this corresponding relation is kept among the PHR;

1.3 when the terminal call dispatching desk, it is dispatching desk that PHR (dispatching home location register) analyzes called, after authentication was passed through, PDS (dispatch server) sent the called dispatching desk instruction of paging to DAS (dispatching desk server), carried the positional information of caller in the paging instructions; Dispatching desk is selected specific dispatcher, finishes this calling.

In such scheme, DAS searches available dispatcher according to calling subscriber's positional information, if available dispatcher is arranged, then call request is notified to these dispatchers; If there is not available dispatcher, the default dispatcher of paging then; The dispatcher responds paging, the call setup success; The dispatcher does not respond, call denial.

Available dispatcher's condition is: dispatching desk is current to exist exercisable dispatcher, and this dispatcher's compass of competency comprises the band of position at caller place, and this dispatcher has the authority to calling subscriber's scheduling.When a plurality of available dispatcher, the foundation of response is earlier called out, and authority is replied in other automatic cancellation.

The positional information of the caller among the present invention can be sub-district, area or deployment position district in logic physically.

Difference with the prior art of the present invention is, it or not restriction call, but direct the call to the dispatcher of nearest service, share unified dispatching desk number between a plurality of dispatchers, when the user dials in different geographical position, system inserts nearest dispatcher automatically, can make things convenient for allocate resource, handles the problem of calling out.Only rely on the group system in-house facility to realize.

Embodiment

Be described in further detail below in conjunction with the enforcement of accompanying drawing technical scheme:

The network structure of Digital Clustering such as Fig. 1, each part is described as follows:

MS: colony terminal, can support storing subscriber information, group information, dispatch location area is judged, the terminal equipment of group services such as response paging;

BSS: 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;

PDS: dispatch server, functions such as the calling control of realization trunked call, right of speech management;

PHR: dispatching home location register, preserve cluster user and group log-on message and positional information, comprise the mapping relations between dispatching desk/dispatcher/band of position, realization is to authentication, mandate and the billing function of cluster user, and the position is upgraded and group management function;

PHR Agent: handling desk can directly manage group, group and user, as distributing authority etc.;

DAS: the dispatching desk server, handle the service request that the dispatching desk client is sent;

DAC: the dispatching desk client, comprise dispatching desk and turnkey console, dispatching desk carries out scheduling operation by the dispatcher, comprises making a call query State, recording etc.; Turnkey console by the keeper carry out to the group division, bookkeepings such as user right; Dispatching desk and dispatcher's position-based route is in the turnkey console setting.

Fig. 2 is a deployment position district exemplary plot, is described as follows:

DLA:Dispatch Location Area deployment position district, deployment position district are logical concept, are made of one or more sub-districts.Operator is according to the actual needs of the network planning, and the overlay network of system is divided into several dispatch location area.

The present invention at first will go out the band of position according to the system call demand planning, and the band of position can be divided according to sub-district, area or dispatch location area principle.The deployment position district is individual notion in logic, and least unit is that the sub-district also can be the set of a plurality of sub-districts.With Fig. 2 is example, and DLA200 is the set that sub-district 201, sub-district 202 and sub-district 203 are formed together.

The present invention proposes deployment position district in logic, more meet the group system service characteristics.But, can further one or more dispatch location area be constituted the dispatch service zone in order to limit the service range of cluster service.

The present invention will divide dispatching desk subordinate's dispatcher according to the administration band of position, set up the mapping relations between dispatching desk/dispatcher/band of position, and this corresponding relation is kept among the PHR;

In network coverage, dividing dispatcher-controlled territory (sub-district, area or deployment position district) as required, and dispatching desk subordinate's dispatcher divided according to the administration band of position, set up the corresponding relation between dispatching desk/dispatcher/band of position, and this corresponding relation is kept under the prerequisite among the PHR, the step when colony terminal is called out the degree of regulation platform is as follows:

301: colony terminal is initiated the calling to dispatching desk;

302:PDS sends the Access-Request message to PHR, to ask calling/called subscription authentication.It is dispatching desk that PHR analyzes called, and after authentication was passed through, PDS sent the instruction of call scheduling platform to DAS, carries the caller location relevant information in the instruction.

303:DAS judges further whether this dispatching desk exists qualified dispatcher, and Rule of judgment is: there is exercisable dispatcher in the current scheduling platform; The schedulable band of position of this dispatcher scope has comprised the band of position at caller place, and the dispatcher has the authority to user's scheduling.These conditions satisfy simultaneously, are qualified dispatcher.

304: if there is the dispatcher satisfy condition, the DAS dispatcher that notifies all to satisfy condition beep-page message then.Because of the dispatcher who satisfies condition simultaneously has a plurality ofly, system takes whole notices, and a dispatcher responds earlier, other dispatchers just automatically cancellation reply the principle of authority.

305: the dispatcher who if there is no satisfies condition, then DAS notifies default dispatcher with beep-page message.

306: as the dispatcher reply timer to before responded the paging request, then call setup success.As the dispatcher reply overtime, reject response call failure then.
