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.
