Embodiment
Consult shown in Figure 4ly, CDMA belongs to ansi standard, therefore, the present invention is based on wireless intelligent network (WIN) agreement, and its bearing bed is ANSITCAP.Mutual annexation still adopts existing UI interactive interface in the existing WIN standard between SCP and the IP, and the UIScript interactive interface meets existing connection mechanism.
The perfect UIScript interaction mechanism that provides in the INAP standard is provided in the present invention, can improve the reliability of interface so on the one hand, equipment (SCP and IP) is supported also than being easier to simultaneously, if this equipment can be supported fixed network and C net simultaneously, then code can finely be reused, and finally makes UIScript interactive interface compliant as far as possible.
Main flow process of the present invention following (consulting the Digital ID among Fig. 4):
1, the user dials access code, calls out to be linked into MSC/SSP.
2, MSC/SSP finds it is the calling of intelligent subscriber, and calling is reported SCP.
3, trigger the service logic of SCP, need to be initiated to the mutual request of IP in IN service, instruct MS C/SSP is connected to the IP of appointment.
4, MSC/SSP is according to the indication foundation of SCP and the link between the IP.
5, IP is behind the link between foundation and the SSP, and the message that the transmission connection has been set up is to SCP.
6, SCP indication IP carries out the script of appointment.
7, the VocieIE of IP obtains corresponding ICP (Internet Content Provider, Internet Content Provider) according to the information among the UIScript to PortalServer, judges whether whether this ICP register at PortalServer.
8, PortalServer feeds back the log-on message of corresponding ICP.
9, the ICP of the message of appointment script to correspondence obtained in the IP transmission.
10, ICP returns the VXML page of appointment.
11, Voice IE explains and carries out Voice XML flow process script, and control IP-SP and telephone subscriber carry out alternately, as: playback notice, playback also collect the digits.
In the present invention, definition UIScript interactive interface is four operations: script operation (ScriptRun), script event (ScriptEvent), script information (ScriptInfo) and script are closed (ScriptClose), and other are operating as the WIN standard and define.
Can there be repeatedly ScriptInfo and ScriptEvent mutual between SCP and the IP, the two hockets, a ScriptInfo is promptly arranged, must have a ScritptEvent corresponding with it, one has a try, and keeps mutual continuing, how many times is mutual as for carrying out, depend on business norms, script and IN service are corresponding, and both sides are consistent.
The signaling protocol stack of ANSI shown in Fig. 5 A, more than four operations be in the WIN standard, to expand, bearing bed is ANSI TCAP, has interface between application layer WIN and the bearing bed ANSI TCAP.
UIScript based on CDMA is mutual, and the carrying of ANSI TCAP layer need meet the treatment mechanism of ANSI TCAP.Realization of the present invention is shown in Fig. 5 B, and ScriptRun operates in bearing bed and carries away (abbreviation that TC_CWNP is Transaction Capabilities_CONVERSATION WITH PERMISSION) by TC_CWNP+TC_INVOKE message.ScriptClose operation, ScriptEvent operation and ScriptInfo operate in bearing bed and carry away (TC_CWP is Transaction Capabilities_CONVERSATION WITHOUTPERMISSION abbreviation) by TC_CWP+TC_INVOKE message.(in detail interface definition is referring to ITUT Q1228E standard, and Chinese standard is referring to " China can just collect the Intelligent Network Application Protocol (INAP) in 2 stages ").
In specific implementation, the command code of four operations is defined as follows:
opcode-scriptInfo Code::＝local:108
opcode-scriptEvent Code::＝local:109
opcode-scriptRun Code::＝local:110
opcode-scriptClose Code::＝local:111
Consult shown in Figure 6ly, the mutual handling process of UIScript is as follows between SCP and the IP:
1, SCP sends the IP of SEIZERESOURCE to appointment, obtains resource.
2, IP returns the result who obtains resource and gives SCP.
3, SCP sends CONNECTRESOURCE to SSP, allow SSP continue and IP between link so that the ability of interactive voice is provided for follow-up reciprocal process.
4, IP set up and SSP between link after, send INSTRUCTIONREQUEST to SCP, tell SCP that link is set up, SCP can finish follow-up mutual.
5, SCP issues script operation (ScriptRun) indication and gives IP, and the script that indication IP calls ICP to be provided is also carried out.
6, IP reports the result of execution by ScriptEvent.
7, SCP receive IP report behind the Script result, if also need and IP between other information interactions are arranged, then send ScriptInfo to IP.
8, IP continues to carry out script after receiving the ScriptIndo of SCP, reports ScriptEvent once more when the trigger condition of the ScriptEvent that reports arrives, and repeats 6), 7) and 8).
9, after script executing finished, IP reported last ScriptEvent (whether have among the ScriptEvnt is the Warning Mark of last Event).
10, SCP issues ScriptClose indication IP to SCP and closes script after receiving last Event of IP.
11, SCP issue that DISCONNECTRESOURCE splits off and IP between link, SSP after the DISCONNECT indication that receives SCP, remove and IP between link.
12, after SCP issues insteuctrequest, the indication IP discharge the mutual resource of this UISceipt, as the dialogue etc.IP discharges resource after receiving indication.
Because the mutual implementation time of user's script between SCP and the IP is longer, for guarantee both sides synchronously, need activate test, the treatment mechanism that activates test as shown in Figure 7:
1, SCP activates test (activating test) intervalometer issuing to be provided with after ScriptRun issues.
2, SCP removes the AT operation timer after receiving ScriptEvent, resets the AT intervalometer.(annotating: if be last ScriptEvent, and be to allow IP to take out stitches, then do not reset timer)
3, SCP resets the AT intervalometer after issuing ScriptInfo.
4, SCP removes AT intervalometer and operation timer after issuing ScriptClose.
Operation timer is defined as follows:
| Action name | Timer | Timer value |
| Close script | Tcl | 5s |
| Script information | Tinf | 5s |
| Script event | Tre | 5s |
| Run Script | Tru | 300s |
Below provide the audible ringing tone service in the C net described said method as application example:
The user can pass through the service provider, and (Service Provider SP) goes up the WEB page and revises ring-back tone, and the ring-back tone confession user that operator or SP place characteristic in the website in the WEB website selects, or the user uploads oneself ring-back tone is provided.The user also can be by the ring-back tone of phone flow custom oneself simultaneously, its essence is still called the modification process of SP, be to pass through phone only at this moment, triggering intelligent network service, intelligent network business by and IP between the UIScrip interactive interface, call the script that SP provides, concrete flow process is referring to shown in Figure 8:
(1) user dials the ring-back tone access code, and MSC reports ORIGINATIONREQUEST to give SCP.
(2) SCP detects this user's CAMEL-Subscription-Information and user's remaining sum, detects by issuing originationreauest and gives MSC, and indicating call continues.
(3) MSC detects called number and prepares routing call, triggers trigger again and reports AnalyzedInfomation to give SCP.
(4) SCP captures resource to the IP of appointment, the result that the IP report is captured.
(5) SCP sets up link between MSC and the IP to MSC request, and MSC sends the IP that IAM (Initial Address Message, initial address message) gives appointment after receiving this request, ask to set up link.
(6) IP reports INSTRUCTIONREQUEST to set up to SCP indication link, and reports ACM simultaneously (Address Complete Message, the address is complete).
(7) SCP issues ScriptRun and gives IP, and the ring-back tone that indication IP calls SP to be provided is revised script, and carries out and reported result.
(8) SCP issues ScriptClose and gives IP after receiving last Event of IP, and indication IP closes script.
(9) SCP issue DISCONNECTRESOURCE to MSC indication remove with IP between be connected.
(10) MSC issues REL (Release discharges) and discharges link to IP after the request that receives SCP; IP reports RLC (Radio Link Control, Radio Link control) to give MSC to MSC after discharging resource.
(11) SCP issues instructionrequest and gives IP, and indication discharges relevant dialogue resource, and issues anlyzeinformation simultaneously to MSC, end of conversation.
