Abstract

The method comprises: dividing the UEs in the group into two types -enhanced members and traditional members; during the call, PDS saves the dispatch location area (DLA) where the called terminal locates at, gets the members' type of each terminal and the DSA of the group from the authentication confirmation message returned from PHR; if the PDS judges the calling terminal is traditional terminal and is not at DSA of the group, then it rejects the call; otherwise, it sends the paging message to each enhanced member, and sends traditional group paging message to all BSS in DSA; after BSS receives the paging message, it establishes STDL with PDS, and allocates resources for users' terminal, and returns the message of competing the establishment; after the {DS receives the message of completing the establishment from terminal or BSS, the call establishment succeeds.

Description

CDMA digital packet formula and enhanced are called out fusion method

Technology neck city

The present invention relates to moving communicating field, relate in particular to the control method of trunked call process in CDMA (code division multiple access access) digital cluster system.

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, it distributes air traffic channel separately for each cluster user terminal when carrying out trunked call, 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 different with existing professional trunked call, so be called the enhanced group calling;

Another kind is a traditional group call, its all users when trunked call share all forward direction and backward channels, capture terminal forward direction shared service channel inserts to be called out, like this as long as user terminal just can insert calling in the range of transmission of trunked call forward shared channel, also just realized single sub-district limitless volumes, this calling performance is similar with existing professional trunked call, so be called traditional group call, certainly be subjected to signal power limitations, this calling can't resemble enhanced allows user terminal break through geological restraint calling out.Flow process and resource distribution mode about traditional group call can be 200510134219.1 with further reference to application number, name is called the patent application of " call setup of CDMA traditional packet digital calling and calling-control method ", and application number is 200510134220.4 and is called the patent application of " a kind of implementation method of CDMA traditional packet digital calling talk process ".

Call out in group system and be limited in certain territorial scope usually, if colony terminal 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 is illustrated to be described as follows as Fig. 1:

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;

Dispatch location area 102: dispatch location area (DLA, Dispatch Location Area) is the least unit of limited range in the CDMA standard digital cluster call, it is the set of sub-district, as example DLA_1 to DLA3, dispatch location area may diminish to and includes only a sub-district, and DLA_1 includes only Cell_2 as example, and DLA_3 includes only Cell_5, also a plurality of sub-districts be can comprise, Cell_3 and Cell_6 comprised as example DLA_2.

Dispatch service zone 103:, dispatch service zone (DSA, Dispatch Service Area) be the set of dispatch location area, as example DSA_1 to DSA_2, the group in the trunked call can be distributed in this dispatch service zone, limit the scope of this group trunked call service, DSA_1 comprises DLA_1 as example, DLA_2 and DLA_3.

It is the fusion that enhanced and traditional type are realized in the basis that the present invention mainly discusses in the CDMA2000 digital cluster system with the traditional type calling, traditional type is called out under the situation of Channel Sharing in the prior art, consider the signal power problem, be actually and dispatched region limits, call initiator must make a call in specifying the dispatch service zone, and exhaled terminal also can only in specifying the dispatch service zone, receive voice and forward direction message, yet in the actual use of group system, have such situation, the user wishes that initiation can held a large number of users to calling and this group of a group in certain zone outside the dispatch service zone, be that the user initiates traditional type and calls out outside the dispatch service zone, even wish in traditional type is called out, can also comprise that not user terminal in the dispatch service zone and roaming user terminal are as being exhaled terminal.Like this, no matter to be that enhanced is called out or the traditional type calling all can't be met consumers' demand.

Summary of the invention

The technical problem to be solved in the present invention provides a kind of in CDMA2000 digital cluster system traditional type and enhanced calling fusion method, realized promptly that traditional type is called out in certain area contents and received the needs of a large number of users, satisfied again and exhaled terminal and exhaled terminal not to be subjected to the needs of this group scheduling coverage restriction.

Design of the present invention is: utilize the enhanced group calling that user terminal is set up the characteristics of channel separately, can realize that with the traditional type shared channel characteristics of sub-district, appointed area limitless volumes merge, to solve the problems of the technologies described above.This method claims not to be subjected in the group enhancement mode member of the user terminal of this group scheduling coverage restriction for group for convenience of explanation, and the base station is set up channel separately to it in call establishment; Claim to be dispatched in the group the traditional member of the user terminal of coverage restriction for group, access base station is for setting up upright shared channel in call establishment.

In order to solve the problems of the technologies described above, the invention provides a kind of CDMA digital cluster system traditional type and enhanced and call out fusion method, comprise call establishment, this process may further comprise the steps:

(a) user terminal that group is comprised is divided enhancement mode member and traditional member two classes, and the information of this member's classification is kept at dispatching home location register;

(b) in the call establishment, dispatch server is preserved rising of comprising in the call request and is exhaled terminal place dispatch location area information, and knows the member's classification under this group scheduling coverage and each terminal from the authentication responses message that dispatching home location register is returned;

(c) to exhale terminal be traditional member and not in this group scheduling coverage to this dispatch server as having judged, then refusal is called out, finish, otherwise, each enhancement mode member in this group sends independent beep-page message, and all base station sub-systems are sent out the traditional group call beep-page message in the dispatch service zone;

(d) base station sub-system is received by described independent beep-page message or/and behind the traditional group call beep-page message, shared cluster data link between foundation and the dispatch server, be the user terminal Resources allocation, and finish message to the foundation that the foundation that dispatch server returns traditional member is finished message or transmitted the enhancement mode member;

(e) this dispatch server receives the foundation that the enhancement mode member returns and finishes message or/and message is finished in the foundation that base station sub-system is returned in the coverage, the call setup success.

Further, said method also can have following characteristics: in the described step (d), each base station sub-system and dispatch server are only set up a shared cluster data link in call establishment, be used to transmit the business datum of all enhancement mode members and traditional member under this base station sub-system.

Further, said method also can have following characteristics: in the described step (c), roam into the coverage of another dispatch server if any user terminal as the enhancement mode member, then this dispatch server sends the paging request to the roaming place dispatch server earlier, is forwarded to the user terminal of this roaming again by this roaming place dispatch server.

Further, said method also can have following characteristics: the described described independent beep-page message that sends to the enhancement mode member is meant the beep-page message of the normal voice calls that sends by international travelling carriage identification code, base station sub-system also is to adopt the channel allocation mode of normal voice calls to distribute independent channel when being this user terminal allocated channel, returns to set up after enhancement mode member inserts and finishes message.

Further, said method also can have following characteristics: after described step (d) base station sub-system is received the traditional group call paging, set up the shared service channel resource of eating dishes without rice or wine, and to its control range intercycle transmission broadcast channel assigned message, this is organized traditional member and catches the shared service channel for this call setup of base station sub-system in this zone according to the parameter of carrying in this message, independently inserts this calling.

Further, said method also can have following characteristics: also comprise the voice repeating process, this process may further comprise the steps:

(f) terminal of acquisition right of speech sends reverse speech frame to base station sub-system, is the enhancement mode member as this terminal, then send by independent reverse traffic channel to its distribution, if traditional member, then by being the upright shared reverse traffic channel transmission of this establishment;

(g) described base station sub-system is by between itself and dispatch server be the shared cluster data link speech frames described dispatch server extremely of this call setup; Described dispatch server is transmitted speech frame to call out all shared cluster data link of being set up for this;

(h) after the base station sub-system of every shared cluster data link opposite end is received speech frame, by for its forward traffic channel of setting up separately sends speech frame separately, is simultaneously that the traditional member's of this call setup forward direction shared service channel sends speech frame to the non-member of speaking of enhancement mode under described base station sub-system.

Further, said method also can have following characteristics: after dispatch server is received the speech frame that base station sub-system sends in the described step (g), if roaming user terminal is arranged, then transmit speech frame, pass through the shared cluster data link of foundation to the base station sub-system speech frames by this roaming place dispatch server again to the dispatch server of its roaming place.

Further, said method also can have following characteristics: also comprise the calling dispose procedure, this process may further comprise the steps:

(i) enhancement mode member or traditional member initiate to discharge the request of group calling to dispatch server;

(j) dispatch server is received all enhancement mode members in this group of this request back search, sends release command by international travelling carriage identification code separately to these members, and all base station sub-systems transmission traditional type release commands that relate to this calling;

(k) the enhancement mode member receives after the release command to return to dispatch server and withdraws from this behind the Release complete and call out, and receives that the base station sub-system of release command is released to the shared service channel of this call setup, returns Release complete to dispatch server then.

As from the foregoing, the present invention has realized traditional type call origination terminal and has been exhaled terminal not limited by this group scheduling coverage, even can roam at the CDMA2000 digital cluster system.Can satisfy the growing function needs of cluster user variation.

Embodiment

Traditional type of the present invention and enhanced fusion method are based on the CDMA2000 digital cluster system, its network diagram such as Fig. 1, and each part is described as follows:

Colony terminal (MS): the terminal equipment that can support group services such as storing subscriber information, group information, dispatcher-controlled territory judgement, response, group calling paging.

Base station sub-system (BSS): comprise the transceiver (BTS) of supporting trunked call, base station controller (BSC) and with the mutual dispatching client (PDC) of network side.

Dispatch server (PDS): realize the calling control and the right of speech management of trunked call.

Dispatching home location register (PHR), the log-on message and the positional information of preservation cluster user and group realize authentication, mandate and billing function to cluster user, and the position is upgraded and group management function;

Share cluster data link (STDL, Shared Trunking Data Link), it is the carrying that voice are transmitted between base station sub-system and the dispatch server, between setting up in the process by PDC and PDS, consults trunked call to set up, be used to transmit all forward directions or the reverse traffic data (voice flow) of calling, talker's voice by the BSS that eats dishes without rice or wine after, send to PDS by BSS by the STDL that between PDC and PDS, sets up again, PDS is at the voice of calling out all related STDL forwarding talkers to this, and STDL discharges when calling out release.

Below in conjunction with accompanying drawing embodiments of the invention are described in further detail.Also will be in explanation embodiment step in conjunction with an application example.Please refer to Fig. 1, suppose existing 3 terminals, MS_1, MS_2, MS_3 are dispensed in dispatching home location register in the same traditional type group, are called Group_1, and the dispatch service zone of Group_1 is made as DSA_1.These 3 user terminals are authorized different authorities respectively as the member of same Group_1, represent dissimilar group memberships, and MS_1 represents traditional member, and are limited in Group_1 dispatch service zone; MS_2, MS_3 represent the enhancement mode member not limited in Group_1 dispatch service zone, wherein the MS_2 representative makes a call, the user terminal that obtains right of speech or make a call and discharge, MS_3 then represents other all enhancement mode member, comprises the enhancement mode member that roaming takes place.Since before need setting up separately the enhancement mode member/and backward channel, take very much interface-free resources, so need that in same group the enhancement mode member is had quantitative control, this quantity can be configured according to the existing network capacity.

As shown in Figure 1,3 terminals distribute as follows: MS_1 belongs to the DSA_1 of Group_1 at DLA_1; MS_2 belongs to the DSA_1 of Group_1 at DLA_3; MS_3 does not belong to the DSA_1 of Group_1 at Cell_7.Application example will initiate rising of Group_1 exhaled by MS_2, and the voice that MS_2 obtains after the right of speech send, and MS_2 initiates to setting up three processes of release that Group_1 group Group_1 exhales the respective streams journey to be described.

Fig. 2 is the call setup flow chart of present embodiment, and this flow process may further comprise the steps:

Step 201, the user makes a call, rise exhale terminal call request through base station sub-system (BSS), dispatch server (PDS) sends to dispatching home location register (PHR) and carries out authentication, needs to have carried in call request to exhale the present place of terminal dispatch location area (DLA);

As follows in conjunction with Fig. 1 example, MS_2 initiates the calling to Grroup_1, and this calling is called Call_1 for the ease of following discussion spy, wherein carries the current place of MS_2 dispatch location area DLA_3 in the call request message.

Step 202, dispatching home location register is carried out authentication to call request, mainly be to judge that this user terminal has a call right of unmatchful group etc., then the group id (GID, Group ID) that will organize of dispatching home location register, dispatch service zone, rise exhale user terminal whether have in enhancement mode member, the group those Called Subscriber terminals (called) and whether information such as enhancement mode member exhale the response message of authentication request to send to dispatch server by rising;

Group id (GID) is the unique identification number giving the group fixed allocation of the whole network in dispatching patcher.In example, the information that dispatching home location register feeds back to this calling of dispatch server comprises: GID, dispatch service region D SA_1, work that to exhale user terminal be to have two classes called in enhancement mode member, the group, the enhancement mode member of the traditional member of MS_1 representative and MS_2 representative etc.

Step 203, dispatch server is received and has been judged whether enhancement mode member of the person of exhaling after the authentication responses, if the enhancement mode member then no longer further judges the scheduling district, directly send by the paging of IMSI or be called paging to the enhancement mode caller (caller rise exactly the person of exhaling/rise and exhale terminal) caller, if traditional member judges that then it is whether in the dispatch service zone that group is set, if not in the dispatch service zone then exhale terminal to send call rejection message to rising, Reason For Denial is " exceeding the dispatch service district ", finishes; If in the dispatch service zone, then rise and exhale flow process to send the traditional group call paging to the corresponding base station subsystem by traditional group call;

So far, just can realize allowing to exist in the traditional group call enhancement mode member, can allow these enhancement mode member do not dispatched the coverage restriction and initiate traditional group call by this method.

In conjunction with example of the present invention: terminal MS _ 2nd, the enhancement mode member of Group_1 is so dispatch server directly sends the paging (to enhancement mode caller paging) of pressing IMSI to it.

Step 204, the paging by IMSI of having issued the person of exhaling will be earlier through base station sub-system, base station sub-system judges it is a new group calling according to GID, then sends cluster data link (STDL) the foundation request of sharing by dispatching client (PDC) to dispatch server (PDS);

Corresponding base station may be received enhanced user by the paging of IMSI with to the traditional group call paging of base station, receive which kind of paging request PDC only sets up a STDL for same group current calling to the PDS request, if set up one then no longer send the STDL request of setting up to PDS, no matter be enhancement mode or traditional member, all reverse voice all send to PDS by same STDL.So just realized voice are transmitted the fusion of carrying STDL.

Step 205, dispatch server are distributed the STDL request of setting up of response scheduling client after the STDL resource of this time calling, send STDL to dispatching client and set up and reply;

Step 206, dispatch server are judged when comprising enhancement mode called in the authentication responses, are sent the paging request of pressing IMSI to these terminal calleds;

In the example, MS_3 do not belong to the dispatch service region D SA_1 of Group_1, but it is the enhancement mode member at Cell_7 in Group_1, so still can send the paging request to it.MS_3 even can represent the terminal that roams into other dispatch server compass of competency is transmitted to roaming terminal by it as long as send the paging request to the dispatch server of its roaming place.

So just can solve in the traditional type calling the called problem that can not dispatched the coverage restriction even have roaming condition.

All related in the dispatch service zone that step 207, dispatch server are returned in authentication responses base station sub-systems send the traditional group call paging;

Purpose is in order to allow all base station sub-systems in this group scheduling coverage scope set up shared service channel resource to traditional member in its control range.

Step 208 after the base station sub-system of receiving the traditional group call paging is set up the shared service channel resource of eating dishes without rice or wine, to its control range intercycle transmission broadcast channel assigned message, is mainly carried GID, DSA, Wash sign indicating number, information such as Long Code Mask;

If this organizes traditional member in its dispatch service zone, then can receive broadcast channel assigned message, and catch the shared service channel of base station sub-system in this zone for this call setup according to the relevant parameter that this message is carried, independently insert this calling.As example, MS_1 receives the shared service channel to traditional member of the autonomous Call_1 of access behind the broadcast channel assigned message of base station sub-system.

Step 209 rises and exhales enhancement mode member (caller) time foundation to finish message;

In the example, MS_2 responds its paging, returns to set up and finishes message.

Step 210, enhancement mode member's (called) returns to set up and finishes message;

In the example, MS_3 responds its paging, returns to set up and finishes message.

Step 211, base station sub-system are received its traditional group call paging and message is finished in the foundation of having returned base station sub-system to dispatch server after having set up interface-free resources;

Step 212, dispatch server are received caller (enhancement mode member), and this group of judgement was set up the notice dispatching home location register after message was finished in the foundation of called (enhancement mode member) and base station sub-system.

It should be noted that in the above-mentioned flow process, to the unfixing order of the step of multiple called paging, and the permanent order that also do not have of the response of each time paging.Only example shown in the figure.

From top flow process as can be seen, establishment after traditional type and enhanced merge is upright will no longer to be that judgement or simple traditional group call judgement are set up in simple enhanced group calling, this determination strategy can be formulated according to concrete needs, but consider that the enhancement mode member can return foundation separately and finish message, and traditional member just unifies back the situation that message is finished in a foundation by base station sub-system, finishes foundation that quilt that message adds any one enhancement mode member recalls such as: the foundation of returning with enhancement mode member's caller and finishes message or finish message with the foundation that enhancement mode member's caller is returned and add the foundation that any one base station sub-system returns and finish the sign that message is set up as group calling.

Fig. 3 is the voice forwarding process figure under traditional type and the enhanced fusion situation, may further comprise the steps:

Step 301, the terminal that obtains right of speech sends reverse speech frame by eating dishes without rice or wine to base station sub-system, as terminal be the enhancement mode member then it sends by the independent reverse traffic channel to its distribution eating dishes without rice or wine, if traditional member then needs by the upright shared reverse traffic channel transmission of this establishments;

In the example, MS_2 is the enhancement mode member and has obtained right of speech that in this calling Call_1 then this terminal sends speech frame by independent reverse traffic channel to its distribution to base station side.

Step 302, base station sub-system is by being the STDL of this call setup between itself and the dispatch server, speech frames is to dispatch server;

Step 303, dispatch server is transmitted speech frame to call out all STDL that set up for this, if roaming user terminal is arranged, then transmit speech frame to the dispatch server of its roaming place of control, pass through the STDL of foundation to the BSS speech frames by this roaming place dispatch server again;

Step 304, the opposite end base station sub-system of every STDL are received behind the speech frame that dispatch server transmits according to the group that is kept in its database and user profile to the non-member of speaking of enhancement mode by sending speech frame separately for its forward traffic channel of setting up separately;

As Fig. 2: base station sub-system sends speech frame separately to MS_3.

Step 305, base station sub-system sends speech frame at the forward direction shared service channel that is the traditional member of this call setup when the enhancement mode member sends speech frame separately under it.

Fig. 4 is that the calling under present embodiment traditional type and the enhanced fusion situation discharges flow chart, may further comprise the steps:

Step 401, user terminal initiates to discharge the request of group calling, no matter is that enhancement mode member or traditional member all can initiate to discharge request;

In the example, initiate release request as the enhancement mode member to Call_1 in conjunction with Fig. 1 example and Fig. 4: MS_2.

Step 402, dispatch server are received after the release group calling request of certain terminal all enhancement mode members in this group of search, to these members transmission release command of pressing IMSI separately;

In the example, as Fig. 4: base station sub-system is to MS_2, and MS_3 sends release command.

Step 403, except sending release command separately to the enhancement mode member, dispatch server also will send the traditional type release command to all base station sub-systems that this calling relates to;

The traditional type release command with the enhancement mode member is that by the release command main difference that IMSI sends it is not with the IMSI information at concrete member.

Step 404, enhancement mode member withdraws from this calling after receiving after the release command and returning Release complete to dispatch server;

In the example, receive that as Fig. 4: MS_2, MS_3 responding Release complete after the release command withdraws from Call_1 then;

Step 405 receives that the base station sub-system of release command is released to the shared service channel of this call setup, returns Release complete to dispatch server then;

After interface-free resources was released, the traditional member who inserts this calling shared channel caught less than shared channel resources and just withdraws from automatically.

In the example, catch less than withdrawing from Call_1 behind the forward shared channel of Call_1 automatically as Fig. 4: MS_1;

In sum, the present invention proposes a kind of method of not dispatched coverage limited subscriber terminal problem that may exist when traditional type is called out that in the CDMA2000 Digital Clustering, solves, comprised exhaling not being subjected to this group scheduling coverage restriction and the called coverage of can not dispatched to limit even can roam, finally satisfied the diversified growing functional requirement of cluster user.
