Description

A kind of implementation method of flexible ringing business

Technical field

The present invention relates to implementation method professional in code division multiple access (CDMA) communication system, the implementation method that particularly a kind of flexible alerting (FA) is professional.

Background technology

At present, in cdma communication system, can realize the FA business.So-called FA business, promptly the user dials a number, the ring simultaneously of a plurality of terminals, this number that the user dialled is a guide number, the terminal of a plurality of while rings is referred to as the member.If a member among the FA group replys, then abandon other member's calling branch.A plurality of users can be initiated to the calling of the guide number of FA simultaneously.Guide number may be the number of a member in the group, also may be a virtual number.Member among the FA group does not have the branch of priority, both can be PSTN (PSTN) user, can be the mobile subscriber in this ownership district and non-ownership district yet.

The structure of cdma network is referring to Fig. 1, and Fig. 1 is the structure diagram of cdma network.Wherein, comprise:

Portable terminal (MS) 106 can be CDMA mobile phone, vehicle-mounted travelling carriage etc.

Attaching position register (HLR) 101, the central database of cdma system is stored mobile subscriber's the relevant information of all existence of this HLR control, and the essential information when comprising the user and opening an account comprises the relevant information of the signatory miscellaneous service of user.

VLR Visitor Location Register (VLR) 102 is being deposited the information of mobile user of all visits in its control area among the VLR, the needed total data of management that these information contain MS foundation and call release and roaming and supplementary service are provided.

Service Control Point 105, the business datum of inquiring user provides the processing of miscellaneous service logic for calling.

Mobile switching centre/operation exchange node (MSC/SSP) 103, moving exchanging center MSC is a whole C DMA server, coordinate with control whole C DMA network in each functional entity, be the control centre that realizes user call proceeding, calls out basic functions such as control and business realizing.The service switching point is integrated among the MSC, accepts the service logic control of SCP, finishes the triggering of miscellaneous service idiographic flow and the migration of execution and call state.

Base station sub-system (BSS) 104 directly links to each other with travelling carriage by wave point, is responsible for the management of wireless transmission reception and Radio Resource.Link to each other by the A interface with MSC, realize communicating to connect transfer system information and user profile etc. between the mobile subscriber or between mobile subscriber and the fixed network user.

MS 106 can be in HLR 101 signatory FA business.This business is a kind of general service in the agreement, and this professional realization flow is referring to Fig. 2, and Fig. 2 is the realization flow figure of prior art FA business.Normal flow-non-group user dials the FA guide number, and the FA group among Fig. 2 is PSTN users by three member: FA-DN1, and two other is the mobile phone users MIN1 and the MIN2 in this ownership district, in same MSC service area.Non-group user described in this specification is meant this user not in its FA group who dials, and this user and its FA group who dials be in same MSC, and its flow process may further comprise the steps:

Step 201, non-group user makes a call to originating MS C, and called number is the FA guide number.

Step 202, originating MS C analyzing called number, the result is a mobile number.Originating MS C sends position requests (LOCREQ) to HLR according to called number.

Step 203-206, HLR analyze the guide number that called number is FA, and two mobile member MIN1 and MIN2 register at same service area, and then HLR sends two route requests (ROUTREQ) to VLR, VLR with these two forwards to service MSC.

Step 207-210 after service MSC receives ROUTREQ, for the user distributes two roaming numbers (TLDN), turns back to VLR by route response (routreq) message, and VLR arrives HLR with this forwards.

Step 211, after HLR received all routreq, home position request response (locreq) message was to originating MS C.The routing iinformation that comprises each FA member in the TERMLIST parameter of this message.

Step 212-214, originating MS C receive after the locreq, make a call to FA-DN1, TLDN1 and TLDN2 simultaneously according to above-mentioned routing iinformation.

Step 215, TLDN1 replys, and originating MS C couples together caller and TLDN1, promptly connects mobile phone users MIN1.

Step 216, originating MS C is discharged into the calling of TLDN2.

Step 217, originating MS C is discharged into the calling of FA-DN1.

From above-mentioned process as seen, the scheme in the agreement can realize basic service, though the Call Forwarding No Reply of description situation is arranged in the agreement, other preceding commentaries on classics situations all do not have to describe, and do not describe the interaction relationship of FA and various supplementary services in the agreement.According to the implementation in the agreement, the FA Member Users can not be an intelligent service users, can not be other supplementary services user who removes the Call Forwarding No Reply business.For example: the basic process of IN service is referring to Fig. 3, and Fig. 3 is the simple called trigger trigger process of intelligent service users, and it may further comprise the steps:

Step 301, MSC/SSP sends position request information to HLR.

Step 302, HLR takes back this user's intelligent contactor tabulation to MSC/SSP with position request response information.

Step 303, MSC/SSP tabulates according to intelligent contactor, triggers the initial terminal trigger to SCP.

Step 304, SCP returns the response of initial terminal trigger to MSC/SSP.

Step 305, MSC/SSP sends position requests to HLR.

Step 306, HLR returns the position request response that comprises the TERMLIST parameter to MSC/SSP.

Step 307, MSC/SSP triggers called route can get trigger to SCP.

Step 308, SCP returns called route to MSC/SSP can get the trigger response.

Shown in Figure 3 is a simple process, also comprises other trigger process in practice, does not illustrate among Fig. 3.In this process, MSC/SSP must obtain called subscriber's intelligent contactor tabulation, just might realize IN service; And the realization flow of FA business shown in Figure 2, HLR returns to the routing iinformation that only comprises each FA member in the TERMLIST parameter of position request response (locreq) of originating MS C in the step 211, the specifying information that does not comprise each FA member, that is to say that HLR can't bring back to SSP with the list of triggers on each calling branch, the pre-payment IN services such as (PPC) if the member in this sample ownership district has contracted, MSC/SSP can't trigger the relative trigger device to SCP, cause IN service inoperative.

For the Call Forwarding No Reply service-user of describing in the agreement, the position requests (LOCREQ) that is triggered by the FA guide number is behind HLR, HLR takes back in the request response of position is number rather than former FA member's number information after the preceding commentaries on classics, such problem can appear at MSC: after HLR triggers Call Forwarding Unconditional and divert when busy not to former called information of chargeing, can not be to former called the charging.

This shows that prior art can not be supported FA Member Users's supplementary service and IN service, this makes the FA business not to be widely used.

Summary of the invention

In view of this, the object of the present invention is to provide the professional implementation method of a kind of flexible alerting (FA), can make the FA business be widely used with supplementary service user, intelligent service users as the professional member of FA.

Step 401, non-group user makes a call to originating MS C, and called number is the FA guide number.

Step 402, originating MS C analyzing called number, the result is a mobile number.Originating MS C sends position requests (LOCREQ) to HLR according to called number.

Step 403, HLR is to MSC home position request response (locreq), and wherein HLR directly takes back user 1,2 number to originating MS C by the TERMLIST parameter in locreq.Step 404,405, MSC receives that locreq detects when being the FA business, user 1 and user 2 are triggered new LOCREQ respectively send to HLR, triggering type (TRIGTYPE) value among the LOCREQ is with for the first time different, it is an expanding value, be 254 in the present embodiment, it is defined as FA member's dedicated location request trigger.This trigger represents that this LOCREQ is the LOCREQ at the FA Member Users, can avoid HLR once more user 1 to be used as guide number and trigger the FA calling, loop nesting occurs.

Step 406,407, to judge this LOCREQ be LOCREQ at the FA Member Users to HLR by detecting the TRIGTYPE value, and send route requests (ROUTREQ) for user 1,2 respectively to VLR.

Step 408,409, VLR transmits above-mentioned two ROUTREQ respectively to service MSC.

Step 410,411, service MSC returns two route responses (routreq) to VLR.

Step 412,413, VLR transmits above-mentioned two routreq respectively to HLR.

Step 414,415, HLR returns user 1,2 locreq respectively to originating MS C.

Step 416,417, MSC makes a call to user 1,2 respectively.

Step 418, user 1 replys to set up with caller and is connected, and carries out the required operation flow of caller; If user 2 replys, then user 2 sets up with caller and is connected, and carries out the required operation flow of caller.

Step 419, MSC is discharged into user 2 and calls out.

Embodiment 2:

Comprised two members among the FA group of present embodiment: the mobile subscriber 1,2, and user 1 number is a guide number, and it is in HLR1, and user 2 is in HLR2; And user 1,2 is in same MSC service area.

Referring to Fig. 5, Fig. 5 is the realization flow figure of the FA business of second preferred embodiment of the present invention.The flow process of present embodiment may further comprise the steps:

Step 501, non-group user makes a call to originating MS C, and called number is the FA guide number.

Step 502, originating MS C analyzing called number, the result is a mobile number.Originating MS C sends position requests (LOCREQ) to HLR1 according to called number.

Step 503, HLR1 is to MSC home position request response (locreq), and wherein HLR directly takes back user 1,2 number to originating MS C by the TERMLIST parameter in locreq.

Step 504, MSC receives that locreq detects when being the FA business, triggers new LOCREQ to user 1 and sends to HLR1.

Step 505, MSC triggers new LOCREQ to user 2 and sends to HLR2.

Step 506, to judge this LOCREQ be LOCREQ at the FA Member Users to HLR1 by detecting TRIGTYPE value, and be that user 1 is to VLR transmission route requests (ROUTREQ).

Step 507, to judge this LOCREQ be LOCREQ at the FA Member Users to HLR2 by detecting TRIGTYPE value, and be that user 2 is to VLR transmission route requests (ROUTREQ).

Step 508,509, VLR transmits above-mentioned two ROUTREQ respectively to service MSC.

Step 510,511, service MSC returns two route responses (routreq) to VLR.

Step 512, VLR is to the routreq of HLR1 forwarding to user 1.

Step 513, VLR is to the routreq of HLR2 forwarding to user 2.

Step 514, HLR1 returns user 1 locreq to originating MS C.

Step 515, HLR2 returns user 2 locreq to originating MS C.

Step 516,517, MSC makes a call to user 1,2 respectively.

Step 518, user 1 replys to set up with caller and is connected, and carries out the required operation flow of caller; If user 2 replys, then user 2 sets up with caller and is connected, and carries out the required operation flow of caller.

Step 519, MSC is discharged into user 2 and calls out.

In above-mentioned two embodiment flow processs, increased the process that judges whether at FA Member Users's LOCREQ in the step 406 (506), its subsequent step is all identical with the ordinary call flow process, as seen, called FA member whether same HLR neutralization whether in same MSC the present invention all be suitable for.In addition, for calling subscriber and the called situation of FA member in same MSC, the present invention is suitable equally.

In above-mentioned two embodiment, FA member's intelligent contactor tabulation can be in step 414 (514), 415 (515), locreq with FA member is issued to originating MS C, originating MS C carries out the relative trigger device according to this list of triggers to be installed and triggers, and flow process and common IN service are just the same.

Simultaneously, above-mentioned two embodiment can also well support FA Member Users's various preceding the commentaries on classics: Call Forwarding Unconditional, divert when busy, Call Forwarding No Reply etc.; Can avoid after MSC appears at HLR to trigger Call Forwarding Unconditional and divert when busy not to former called information of chargeing, because according to the protocol in prior art implementation, the position requests (LOCREQ) that is triggered by the FA guide number is behind HLR, and HLR takes back in position request response is number rather than former FA member's number information after the preceding commentaries on classics.And among the present invention, in the position request response by the triggering of FA guide number, HLR can turn back to originating MS C with all FA member's numbers, this moment, originating MS C just had FA member's raw information, can correctly charge, originating MS C does the processing that continues accordingly according to each member's number of FA more then, and for example: HLR etc. is arrived in the trigger position request once more, and flow process and common forward-shifting service are just the same.

In a word, for originating MS C, the above-mentioned step that each Member Users is continued: step 406 (506)-417 (517), with this Member Users do common when called flow process identical, and when forward-shifting service, IN service or other supplementary services took place this user, handling process was also all by the ordinary call flow processing.

This shows that the implementation method that this flexible alerting of the present invention (FA) is professional can be with supplementary service user and intelligent service users as the professional member of FA, make the FA business be widely used, and this method realizes simple, does not run counter to the agreement regulation, the general thought of protocol compliant.
