Fig. 2 is a call flow diagram of the present invention.
Embodiment
As shown in Figure 1, be the basic block diagram of intelligent network, also be a system configuration schematic diagram of the present invention, wherein SCP plays a part control and handles IN service in whole intelligent net system; SSP mainly finishes Service Switching Function and CCF; HLR mainly is the essential information that is used to preserve mobile phone, comprises the signing service information that is used for intelligent call, and when mobile phone location upgraded (mobile phone power-on or mobile phone location change), HLR sent to VLR with these information.
The present invention solves CDMA called subscriber " caller identification " by the following method can't display of calling user cornet problem:
Suppose to have two CDMA user A and user B, they are VPN users of same group.The VPN trombone of user A is 13305190001 (short codes that group distributes is 2001), and the VPN trombone of user B is 13305190002 (short codes that group distributes is 2002), and user A dials user B.In order to simplify flow process, the current same MSC/SSP (for cdma network, general MSC and SSP unify, and are designated hereinafter simply as MSC) that is in of user A and user B in the present embodiment.
In the actual application, the calling subscriber can be the user of any type, can be the GSM mobile subscriber, CDMA mobile subscriber or fixed telephone subscriber, this programme is under these different VPN calling subscriber's situations, so long as on-net call has all been realized " caller identification " display of calling VPN user's cornet.
Below how we describe by flow process and realize " caller identification " display of calling cornet function by existing CDMA net and integrated intelligent network.
Because this programme has made full use of the signaling standard that standard agreement is formulated, can guarantee existing cdma network is not had the influence of signaling conflict aspect, can whether support this number of changing mode to determine whether issuing the DisplayText parameter according to the current MSC of configuration simultaneously, guarantee professional forward compatibility.Fig. 2 is that we have done corresponding expansion to the parameter that uses in the former flow process here with reference to the called basic procedure of CDMA VPN (concrete signaling process can with reference to the standard agreement " PN-4287 " of CDMA), and a detailed process process of present embodiment is as follows:
A, calling user dials is called and call proceeding, user A dials user B, the number of being dialed is the cornet 2002 (user A also can directly dial the trombone 13305190002 of user B) of user B here, the MSC of Calling Side and SCP translate into corresponding called number trombone 13305190002 with called number cornet 2002, obtain the MSC at called subscriber place from HLR, just can be with call proceeding to called.Selective analysis MSC handles called operation flow (because this programme is not made any modification to calling procedure, describe the process of revising calling number for emphasis, just be not described in detail calling procedure here) now.
B, called subscriber trigger intelligent call, it is a CDMA mobile subscriber number that MSC judges this called number, and triggered the Mobile_Termination trigger, MSC sends a LOCREQ message to HLR, major parameter in the message has: TRANSCAP (disposal ability of system is provided with the triggering address list TRIGADDRLIST parameter that cost MSC can handle); WINCAP (WIN0 ability, the trigger of indicating this MSC to support); TRIGTYPE (trigger type is arranged to the trigger Mobile_Termination of this triggering); BILLID (in the signaling relevant, this called subscriber of unique identification) with called subscriber B.
C, HLR return called subscriber's intelligent characteristic, HLR returns locreq message, and the major parameter that comprises has: (trigger address list, the trigger of configuration has TRIGADDRLIST: Initial_Termination, Location, Called_Routing_Address_Available).
D, called subscriber's trigger intelligent business are to SCP, MSC detects in the TRIGADDRLIST parameter of locreq message and has comprised the Initial_Termination trigger, send ANLYZD message to SCP, major parameter in the message has: (trigger type is set to Initial_Termination to TRIGTYPE; CallingPartyNumberDigits (calling number); MDN (called number).
E, SCP are to called subscriber's authentication and analyze called display mode, and SCP is to called subscriber's authentication, if failed authentication, the suspension of service, calling is cut off.If authentication success, then analyze the VPN user that the calling and called user is same group according to calling number that comprises in the ANLYZD message (CallingPartyNumberDigits) and called number (MDN), this time calling is on-net call (being the calling of same group internal).Judge " caller identification " mode of user B, if " caller identification " mode of user B is a display of calling number trombone, then by original flow processing, return the anlyzd response message to the mobile switching centre/Service Switching Point that triggers called service, parameter does not need to do any variation; Mode is a display of calling number cornet if the user is B " caller identification ", Query Database then, find corresponding cornet (2001) by calling number trombone (13305190001), this cornet is deposited in the DisplayText parameter of anlyzd message, send to MSC.Have the DisplayText parameter in the anlyzd message that MSC finds to receive, and analyze and be caller cornet 2001, then preserve this caller cornet.
F, MSC inquire about called routing iinformation to HLR, MSC analyzes the current Location trigger that triggered, send LOCREQ message to HLR, to obtain the current position of called subscriber, the major parameter that comprises has: TRIGTYPE (trigger type, the trigger of being arranged to this triggering is Location).
G, HLR return called routing iinformation to MSC, and HLR returns locreq message, and the major parameter that comprises has: MSCID (identification number of visited MSC, the identification number of the MSC at the current place of expression called subscriber).
H, called subscriber trigger " called routing address can be used " trigger, MSC detects the Called_Routing_Address_Available trigger of indicating in the TRIGADDRLIST parameter, send ANLYZD message to SCP, the major parameter that comprises has: TRIGTYPE (trigger type is arranged to Called_Routing_Address_Available here).
I, SCP are to being called further authentication, and this authentication is mainly analyzed the parameter information that can't obtain in the last ANLYZD message, and determine the rate of this calling, and SCP returns the anlyzd response message.
J, call proceeding be to called, called terminal ringing, and MSC sends alert (ring) message to mobile phone, and the cornet 2001 with the calling subscriber that preserves above in this message sends to mobile phone, and mobile phone just can the display of calling cornet.
K, follow-up handling process are identical with the normal handling flow process, repeat no more here.
