Description

Method and system for triggering multiple intelligent services

TECHNICAL FIELD The present invention relates to the field of mobile communication technologies, and more particularly to a method of multi-intelligent service triggering in a CDMA2000 network system.

Background technique

In the traditional CDMA2000 communication system, as shown in FIG. 1, the intelligent service mainly involves a mobile switching center (MSC), a home location register (HLR), and a service control point of the interconnected core network ( Service Control Point (SCP), in which the MSC and SCP, and the HLR and SCP comply with the Wireless Intelligent Network (WIN) protocol. Users sign up for various smart business triggers in the HLR. When the user initiates or receives a call, the MSC obtains a trigger list of the user subscription from the HLR, and triggers the intelligent service trigger to the SCP according to the trigger of the subscription at each trigger point in the call connection process, and the specific service logic control is completed by the SCP. And instruct the MSC how to proceed to the next step. A typical intelligent service triggering process is shown in Figure 2. The primary and called users are mobile intelligent users, and are currently in the same MSC. The calling party initiates a call, and the MSC loads a series of intelligent service triggers that the user subscribes to. Each calling side triggers a control point, and the MSC queries the smart service trigger of the calling party, and if the trigger type corresponding to the triggering control point is included, the MSC sends a trigger message to the calling party SCP1, such as The type of the trigger corresponding to the trigger control point is not processed, and the MSC processes the called party related data and service information to the HLR to which the called user belongs, and the HLR returns the trigger list of the called subscription. The MSC loads a series of intelligent service triggers called by the called party according to the trigger list, and the call is processed to each called side triggering control point, and the MSC queries the smart service trigger of the called subscription, if the trigger is included in the called The trigger type corresponding to the control point sends a trigger message to the called SCP2, otherwise, according to the normal business process Line processing, when connecting the called, which belongs to the called MSC HLR location information of the called request. In this smart service trigger mode, if a user subscribes to multiple smart services, due to existing The technology cannot send trigger messages to different SCPs or Application Servers (ASs) multiple times at the same trigger control point. It is impossible to enable the same user to subscribe to different services in multiple SCPs or ASs, so it must be in an SCP or AS. All the intelligent services of the user are implemented, which is not conducive to service expansion and network maintenance. When an operator wants to add an intelligent service, all SCPs or ASs on the entire network need to be modified. In order to solve this problem, a method of triggering multiple intelligent services by means of an IP Multimedia Subsystem (IMS) network has been proposed. As shown in FIG. 3, the connection between the MSC and the IMS network is established, and the IMS network is connected to multiple AS servers, and the AS server provides corresponding service processing. For users who need to sign up for multiple intelligent services, only the traditional SCP is contracted to guide the service, and the multiple intelligent services are contracted on the IMS network. The guiding service refers to the manner in which the MSC modifies the call to the IMS network of the user's home location by modifying the routing address through the SCP. Under the direction of the SCP, the CDMA2000 network routes the call to the IMS network, and the IMS network device interacts with multiple AS servers to implement superposition processing of multiple intelligent services, and then routes the call back to the traditional CDMA2000 network to connect the called party. As shown in FIG. 4, when the calling and called users are located in different MSCs and the calling party subscribes to multiple intelligent services, the triggering process includes the following steps: Step 401: The mobile user initiates a call, when the MSC is located (referred to as the main When the MSC) saves the data and service information of the calling user, it identifies the smart user according to the subscription information therein, and loads a series of intelligent service triggers signed by the calling user (only need to sign a trigger to the SCP) Step 402: The call is processed to a certain calling side trigger control point, and the calling party MSC loads the smart service trigger of the calling user, and if the trigger type corresponding to the trigger control point is included, the calling MSC Sending a trigger message to the SCP that is signed by the calling user; Step 403: The SCP identifies that the calling user registers the guiding service, and instructs the calling MSC to modify the routing address to the IMS network to which the user belongs; Step 404: The calling MSC according to the SCP Instructing to route the call to the IMS network to which the user belongs; Steps 405~407: The IMS network interacts with multiple ASs in turn according to the subscription information of the calling user. Control of business; Step 408: The IMS network analyzes the called number, and reroutes the call back to the traditional CDMA2000 network to the MSC where the called party is located (referred to as the called MSC); if the IMS network reroutes the call back to the traditional CDMA2000 network, it needs After being routed to the called MSC through the tandem network, the connected MSC is connected through the tandem network. Step 409: The called MSC connects the called user. When the called party rings, the called MSC reversely transmits a ringing message to the IMS network in the link through which the call passes; Steps 410-412: The IMS network according to the calling party The user's subscription information, in turn, interacts with multiple ASs to perform control of multiple services; Step 413: The IMS network device reversely transmits a ringing message to the calling MSC of the traditional CDMA2000 network in the link through which the call passes; When the called party answers, the called MSC reversely transmits the response message to the IMS network in the link through which the call passes; Steps 415 to 417: The IMS network interacts with multiple ASs in turn according to the subscription information of the calling user. Performing control of multiple services; Step 418: The IMS network reversely transmits a response message to the calling MSC of the calling traditional CDMA2000 network in the link through which the call passes; Step 419: The calling party and the called user enter the call state; Step 420: The called user hangs up and releases the call. The called MSC reversely delivers the release message to the IMS network in the link through which the call passes. Steps 421 to 423: The IMS network sequentially and multiple ASs according to the subscription information of the calling user. Interacting, controlling multiple services; Step 424: The IMS network reversely delivers the release message to the calling MSC of the legacy CDMA2000 network in the link through which the call passes. If the calling and called users are located under the same MSC, they are processed in the same way. The inventor has found that: although the foregoing process implements the multi-intelligent service of the calling user, when the multi-intelligent service solution of the called user is also routed to the IMS network in the same manner, when When the call is routed from the IMS network back to the traditional CDMA2000 network, the MSC that the called party is located will analyze the called number, and then obtain the trigger list of the called subscription from the HLR again, and send the same trigger information to the SCP to trigger the guiding service. Once again routed to the IMS network, resulting in repeated triggering and call routing loops. As shown in Figure 5, the calling and calling parties are in the same MSC and belong to the same IMS network. When the call is routed from the IMS network to the traditional CDMA2000 network, the MSC analyzes the called number and obtains it from the HLR again. The triggered trigger list of the called party sends the same trigger information to the SCP, triggering the pilot service to be routed to the IMS network again, resulting in repeated triggering and call routing loops. The same problem occurs when the calling party is in a different MSC and belongs to the same or different IMS network. Therefore, there is a need to provide a method for enabling a called user to provide multiple intelligent services by multiple SCPs or ASs at the same trigger control point using an IMS network.

The IMS network includes multiple application servers (ASs). The AS is configured to: perform trigger control on one or more called intelligent services. After the processing is completed, the called number is re-numbered (such as adding a prefix before the called number). And then route the call to the MSC where the called party is located in the traditional mobile communication network; the traditional mobile communication network includes the SCP, the HLR and the MSC, wherein the SCP and the HLR and the SCP and the MSC both comply with the WIN protocol. The HLR is the same as the prior art, and the HLR is set to: sign the data and industry of the called user. Information. When the MSC is used as the called MSC, after receiving the call routed back from the IMS network, the MSC is used to trigger the service to the SCP according to the modified called number of the IMS. The SCP is set to: when receiving the request of the MSC, if the trigger type is the initial of the called, the guiding service flow is performed, and the MSC is instructed to route the call to the IMS network; if the trigger type is a special number, the MSC is sent to the MSC. The trigger list of the user configured on the SCP, including a location request (Loca- tionRequest) trigger, does not include the mobile called terminal (Mobile- Termination) triggers the crying port, and the HLR is set to: sign the service information registered by the called user. The user triggers the service trigger list to include the called initial trigger; the MSC is configured to: identify a prefix added by the IMS network before the called number, and trigger the use of the special number trigger to the SCP according to the modified number of the IMS; And receiving the guiding service indication of the SCP, routing the call to the IMS network, receiving the intelligent service indication of the SCP, triggering the location request trigger, and requesting the HLR to request the location information of the called user.

Preferably, the mobile switching center is further configured to: receive a call routed by the IMS network, identify that the called number in the call is a modified called number, trigger to the SCP, and the trigger type is a special number trigger. Receiving, by the SCP, a request for triggering an intelligent service by the mobile switching center, and if the trigger type is a special number trigger, the trigger list of the mobile user saved locally to the SCP returned by the mobile switching center, wherein Include a location request trigger, not including moving the called terminal trigger; and performing call control according to the trigger list, triggering a location trigger according to the modified called number, acquiring location information of the called party from the HLR, and continuing to be call. Or, preferably, the mobile switching center is further configured to: receive a call routed by the IMS network, identify that the called number in the call is a modified called number, and trigger a location request according to the modified called number The trigger requests the called location information from the location home register (HLR) to continue the called party. The mobile switching center is further configured to: receive a ringing message, a reply message, or a release message of the called user, and reversely transmit the corresponding ringing message, response message, or release message to the link through which the call passes. The IMS network, after the IMS network receives the ringing message, the response message, or the release message, according to the subscription information of the called user, sequentially subscribes to the user for one or more of the called intelligent services. The application server (AS) interacts to perform control of the corresponding multiple intelligent services, and then the ringing message and the response The message or release message is passed back to the network where the calling user is located in the link through which the call passes.

The traditional mobile communication network of this embodiment takes a CDMA2000 network as an example, and multiple types of called intelligent services of a user are subscribed to multiple SCPs or AS servers of the IMS network. In the process of triggering one or more intelligent industries of the called user by using the IMS network, the called number is modified by the IMS network, for example, adding a prefix before the called number, and configuring the modified number of the called number on the MSC. The data is analyzed, so that the MSC triggers the special number trigger according to the modified called number to send a message to the SCP to request the called information, and then connects the called party through the instruction of the SCP, without performing the guiding business process. In this embodiment, the called user that subscribes to the multi-intelligent service receives the call request accessed through the Gateway Mobile Switching Centre (GMSC) as an example. When the called GMSC receives the incoming call request, the multi-intelligent service is received. The processing flow is as shown in FIG. 6 (for the sake of clarity, the AS in the IMS network is separately shown), and the following steps are included: Step 601: The called GMSC receives the incoming call request, and analyzes the called number. Step 602: The GMSC identifies that the called user is a mobile user, and requests the called HLR to the HLR to which the called user belongs. According to the 3GPP2 N.S0013 protocol, the GMSC sends a LocationRequest message to the HLR. The type is Mobile Terminal (Mobile- Termination). Step 603: The HLR identifies that the called user is a smart user, and returns a list of triggers signed by the called user to the GMSC. The GMSC loads a series of smart service triggers signed by the called user according to the instruction of the HLR. Step 604: Call processing to a certain A called side triggers a control point, and the intelligent service trigger of the called user loaded by the GMSC, if the trigger type corresponding to the trigger control point is included, the GMSC sends a trigger message to the SCP that is called by the called user; The 3GPP2 N.S0004 protocol specifies that the GMSC sends an analysis message (AnalyzedlnformationRequest), and the trigger type is Initial- Termination. Step 605: The SCP determines that the user subscribes to the guiding service, and instructs the GMSC to modify the routing address to the IMS network to which the called user belongs. Step 606: The GMSC routes the call to the IMS network to which the called user belongs according to the indication of the SCP. Steps 607-609: The IMS network interacts with multiple ASs in sequence according to the subscription information of the user, and performs control of multiple services. 610: After the multiple services are processed, the IMS network reroutes the call back to the traditional

The CDMA2000 network, and modifying the called number, such as adding a prefix before the called number; in this embodiment, the IMS network reroutes the call back to the GMSC in the traditional CDMA2000 network. According to the actual networking situation, the call can also be routed to the MSC where the called party is located in the traditional CDMA2000 network. Step 611: The GMSC analyzes the modified called number, such as analyzing the prefix of the called number, triggering the special number trigger according to the modified called number (prefix) to trigger the intelligent service to the SCP, and the trigger type is filled in as Special number trigger; According to the 3GPP2 N.S0004 protocol, the GMSC sends an analysis message (AnalyzedlnformationRequest), and the trigger type is Special-Caled-Party- Digit-String. Step 612: The SCP determines, by identifying the trigger type in the analysis message as a special number trigger, to return a list of triggers of the called user saved on the SCP to the GMSC, including a location request trigger, but does not include the mobile Calling the terminal trigger; modifying the called number through the IMS network, the GMSC triggers the intelligent service to the SCP by using the special number trigger, and the SCP determines that the current service is not the guiding service according to the trigger type, and no longer indicates that the GMSC is routed to the IMS network. Thereby repeated triggering of the guided service and round-robin routing to the IMS network are avoided. Step 613: The GMSC triggers each trigger according to the trigger list returned by the SCP, and when triggered to the location request trigger, requests the called location information from the HLR; according to the 3GPP2 N.S0013 protocol, the GMSC sends a location request (LocationRequest). Message, the trigger type is location (Location^ Step 614: HLR returns the location information of the called party; Step 615: The GMSC connects the called party according to the location information of the called party, and routes the call to the user MSC; Step 616: The MSC pages and continues to be called, when the called ringing, the MSC forwards the ringing message to the GMSC in reverse; Step 617: The GMSC reversely transmits the ringing message to the IMS network; Steps 618-620: The IMS network interacts with multiple ASs in sequence to perform control of multiple services according to the subscription information of the called user. Step 621: The IMS network reversely transmits the ringing message to the GMSC. Step 622: GMSC The network where the calling user is located transmits the ringing message; Step 623: The called party answers, the called MSC forwards the response message to the GMSC; Step 624: The GMSC delivers the response message to the IMS network; Steps 625-627: The IMS network is based on The subscription information of the called user is in turn interacted with multiple ASs to perform control of multiple services; Step 628: The IMS network delivers the response message to the GMSC; Step 629: The GMSC delivers the response message to the network where the calling party is located; 630: The calling party and the called user enter the call state; Step 631: The calling user hangs up, and the GMSC receives the release message sent by the calling party's network; Step 632: The GMSC delivers the release message to the IMS network; Steps 633~635: IMS The network subscription information of the called user, and a plurality of sequentially AS interaction, a plurality of service control; Step 636: IMS network to the GMSC transmitting the release message; Step 637: GMSC of the release message is transmitted to the called MSC. The above process only takes the example of calling the intelligent mobile subscriber of the local network for the other network user in the CDMA2000 network. When the primary and called users are on the same network, are in the same MSC for intra-office calls, or are in different MSCs for inter-office calls, the called MSC In this embodiment, the GMSC processes the called multi-intelligent service in the same manner, and so on. In other cases, such as roaming, the MSC also processes in the same manner, and the method is also applicable to other traditional mobile communication networks. The devices used in the MSC, GMSC, and other networks for performing mobile switching processing are collectively referred to as mobile switching centers.

In the foregoing steps 611 and 612, the MSC analyzes the modified number, triggers the smart service to the SCP according to the modified called number, and retrieves the trigger list of the user saved on the SCP, where the location request trigger is included, instead of Including the mobile called terminal trigger, the nested trigger of the called user's multi-intelligent service can be realized only by modifying the data configuration on the mobile switching center, the SCP and the IMS network, and the device does not need to be upgraded. In another embodiment, the called user's trigger list (including the location request trigger, the called initial trigger, etc.) is configured only on the HLR, and the software function of the mobile switching center needs to be modified. In step 611, the MSC identifies After the modified number in the call routed by the IMS network, the location request trigger is triggered, and the called location information is directly requested from the HLR, and the called information is not sent to the SCP. Then, step 614 is directly executed, and the HLR is directly modified according to step 614. The data of the called number returns the location information of the called party. The other steps are the same as in the above embodiment, and it is also possible to prevent repeated triggering and round-trip routing of the bootstrap service to the IMS. One of ordinary skill in the art will appreciate that all or a portion of the steps above may be accomplished by a program to instruct the associated hardware, such as a read-only memory, a magnetic disk, or an optical disk. Alternatively, all or part of the steps of the above embodiments may also be implemented using one or more integrated circuits. Correspondingly, each module/unit in the above embodiment may be implemented in the form of hardware or in the form of a software function module. The invention is not limited to any specific form of combination of hardware and software.
