Description

Method and system for adding special-purpose numbers for users

technical field

The invention relates to the technical field of telecommunication network value-added services, in particular to a method and system for adding special-purpose numbers for users.

Background technique

SIM (Subscriber Identity Module) card is sometimes also called smart card, subscriber identification card, and GSM (Global System for Mobile Communications) digital mobile phones must be equipped with this card to be able to use normally. There is a microcircuit chip in the SIM card, which stores the IMSI (International Mobile Subscriber Identity) information, encryption key and other contents of the digital mobile phone customer. The IMSI information on a common SIM card uniquely identifies a customer. When the user turns on the phone, updates the location, etc., the relevant information in the SIM is sent to the MSC (Mobile Service Switching Center) to which the user currently belongs in the communication network through the mobile phone, and the MSC contacts the corresponding HLR according to the IMSI number (saved in the HLR) information corresponding to the IMSI number, such as authentication information, mobile station international integrated services digital network number MSISDN information), and obtain the corresponding MSISDN number. When the user initiates a call, the number displayed externally is the number, which is convenient for other users to call back. The MSISDN number is the user's outgoing contact number. Normally, one IMSI corresponds to one MSISDN number.

As shown in Figure 1, when the calling user calls the MSISDN of the user to the calling MSC (Mobile Services Switching Center) or GMSC (Ingress Mobile Switching Center), the calling MSC or GMSC will go to the corresponding HLR according to the MSISDN Inquire about the actual roaming location of the called party on the (Home Location Register), and the HLR returns a MSRN (Mobile Subscriber Roaming Number) representing the user's current location. In this way, the MSC or GMSC on the calling side can connect to the location of the called user.

The intelligent network is an additional network structure set up on the basis of the existing basic network structure of switching and transmission to provide new telecommunications services (or value-added services) quickly, conveniently and economically. It introduces intelligent functions into the communication network An entity, a network that implements intelligent call control. As the high-level service network of the communication network, the intelligent network can quickly, conveniently, flexibly, economically and effectively generate and realize various new services for the communication network, so that customers can obtain the required information conveniently and flexibly. The most important feature of the intelligent network is to separate the switching function of the network from the service control function, with the support of signaling control capabilities and flexible and powerful software and hardware systems, it can complete flexible business logic processing and instruct the switch to complete the necessary intelligent calls deal with.

Instructing switches to perform routing is one of the most basic functions in an intelligent network. The intelligent network can not only instruct the exchange to continue the original route of this call, but also modify the routing information of this call according to the needs of the business, so that the call can achieve a special route and connect to a specific destination, so as to realize the required value-added business.

The processing method of intelligent network call routing control can be briefly described as shown in Figure 2:

User A calls user B (step a), and user B may belong to the original called office (such as mobile MSC, fixed exchange). Due to the intervention of the intelligent service, when a call occurs or is in progress, the calling office notifies the intelligent network through a trigger message (step b), and the intelligent network determines service processing according to various information, including setting subsequent routes. According to service needs, the intelligent network can modify the routing number of the call, for example, modify it to the called user as C, or directly modify it to a new called office address. In this way, the current call is routed to user C, realizing routing to a specific destination.

In real life, people often need to communicate with various industries or scenarios. At this time, they are always worried that their mobile phone number (MSISDN) will be leaked and will be maliciously harassed in the future. Therefore, they often hope to use the original mobile phone MSISDN number ( Based on the primary MSISDN number), there is another (or multiple) numbers (called secondary MSISDN numbers) for contact on these occasions. From the perspective of portability, users want to use a mobile phone These functions can be accomplished without carrying two or more mobile phones.

In order to realize that one mobile phone of a user can represent multiple numbers at the same time, the following two solutions are generally adopted in the prior art:

1. The method of SIM card integration realizes providing users with multiple MSISDN numbers on a mobile phone, that is, loading the information in multiple SIM cards to a special large-capacity SIM card. From the network point of view, the SIM card The multiple sets of information on the network are still independent of each other, for example, multiple independent IMSIs are required. At the same time, a corresponding menu is provided, so that the user can select a set of information on the SIM card as the currently used information through the mobile phone, thereby providing the user with different external contact numbers.

In this way, only one number can be selected as the currently available number to register to the network for communication, and the rest of the numbers are in the shutdown state. When other users call these currently unavailable numbers, they will hear information such as user downtime. If the user wants to receive these calls, he needs to adopt methods such as voice mailbox, power off call transfer to the main number, etc. At this time, while paying the called fee, the user also needs to pay other fees such as forwarding and voice mailbox service fees. And when the user needs to choose to use another number to initiate a call, he needs to operate the mobile phone to switch. This switching is actually a process of turning off the existing number on the network side and then turning on the new number, so it takes a long time and is very inconvenient for users, especially when frequent switching is required. Moreover, when other users call the secondary number, there is no authentication mechanism. If the number is spread maliciously, the problem of being harassed is still unavoidable.

2. Use a common SIM card and store a set of unique information on the SIM card. When the MSC obtains the MSISDN from the HLR, the HLR obtains different MSISDNs for the same IMSI under different circumstances. This implementation needs to transform the HLR equipment, or place a special device at the front end of the HLR equipment to complete the work. During implementation, different number rules are often generated according to different MSCs that initiate the request, and different numbers may be returned for different time periods. When the calling party initiates a call, this number is used as the calling number. When other users call each number of the user and request the called MSRN, the HLR or special equipment can map it to the MSRN number of the user's primary MSISDN number, so that multiple MSISDNs can be transferred at the same time without setting call forwarding and other functions. Functions that can be accessed.

In this way, since the current external contact number can only be generated for the user according to a fixed rule (such as the MSC or time period where the user is currently located), it is difficult to provide the user with sufficient flexibility to deal with and cope with the problem. Provide different numbers for different people and scenarios. Moreover, the HLR or the previous signaling processing equipment needs to identify the MSISDN information in each corresponding request from all relevant MSCs, and judge whether to provide the service for it, which will greatly affect its processing capability. In this way, when other users call the secondary number, there is also no authentication mechanism. If the number is spread maliciously, the problem of being harassed is still unavoidable.

Contents of the invention

The purpose of the present invention is to provide a method for adding a special-purpose number for the user, to overcome the lack of flexibility in the way the user obtains one or more secondary MSISDN numbers in the prior art, and the lack of authentication when the other party calls the user's secondary number The shortcomings of the mechanism enable users to use the secondary MSISDN number to initiate calls simply and conveniently, and realize the authentication of users who call the user's secondary number, so that the called user is free from harassment, and the operator can provide users with more value-added services .

Another object of the present invention is to provide a system for adding special-purpose numbers for users, so as to enhance the service capability of the existing intelligent network, provide users with more value-added services, and meet various needs of users.

For this reason, the present invention provides following technical scheme:

A method for adding a special-purpose number for a user, the method comprising:

Set one or more secondary numbers and dialing methods corresponding to each secondary number for the user;

When the user initiates a call, the secondary number corresponding to the dialing method will be displayed to the called party, and if the user uses the dialing method corresponding to the secondary number to call the called party for the first time, an initial call will be created for the called party. Authorization information, so as to realize the authorization to the called party;

When other users call the user's secondary number, authenticate the other users to determine whether the other users are permitted authorized users;

After passing the authentication, connect according to the primary number corresponding to the secondary number.

The steps of creating initial authorization information for the called party include:

Record the called number and generate a digital password at the same time;

Send the generated digital password to the user by SMS or voice;

The generated digital password is sent to the called party in the form of a short message.

Preferably, when generating the digital password, an allowed number of incoming calls is also generated.

Optionally, the allowed number of incoming calls is generated according to preset settings.

Optionally, voice prompt information is sent to the user, and the number of allowed incoming calls is generated according to the user's voice prompt input.

The steps of authenticating other calling users include:

Play a prompt tone requiring password input to the other users;

If the password input by the other user is correct, enter the follow-up process;

If the wrong password input by the other user is received, the call is released.

judging whether the number of incoming calls allowed by the other users has been exhausted before playing a prompt tone requiring password input to the other users;

If it has been used up, the call is released.

The method further comprises:

Preferably, when another user calls the user's secondary number and passes the authentication, the "access code" + "calling number" is displayed on the user's phone.

The dialing method corresponding to each secondary number is specifically: "access code" + "called number".

The user applies for the secondary number by telephone, or WWW web page, or short message, or WAP/GPRS method.

A system for adding special-purpose numbers for users, including: a mobile phone network and/or a fixed phone network, a mobile terminal and/or a fixed network terminal, and also includes:

The "one machine with multiple numbers" service platform, database, and authentication server arranged in the mobile phone network and/or the fixed phone network and connected to each other, wherein,

The service platform is the core control device of the service, which communicates and interacts with the switch or service switching point in the mobile telephone network or fixed telephone network through inter-office signaling, so that when the service user answers an incoming call or initiates a service call, pick up the call;

The database is used to store the landline main number or PHS main number or mobile phone MSISDN number of the service user and the corresponding secondary numbers, user registration information, and setting information of the calling number for querying of relevant information and numbers and conversion;

The authentication server is used to authenticate the user who calls the secondary number of the service user;

The service platform and database are integrated in the service control point SCP of the intelligent network of the mobile phone network. When the service user uses the access code to initiate a call for the first time, the SCP issues a secondary number, so as to display the secondary number to the called party and perform authorization processing on the called party.

The SCP authorizing the called party includes: enabling the system to automatically generate a password corresponding to the called party and the number of incoming calls allowed; or performing voice interaction with the service user to realize information customization with user participation .

The mobile telephone network and/or fixed telephone network at least include: Global System for Mobile Communications GSM network, Code Division Multiple Access CDMA network, PHS network and Public Switched Telephone Network PSTN.

As can be seen from the above technical solutions provided by the present invention, the present invention can be implemented on a mobile phone without changing the SIM card of the user by means of the conversion of the intelligent network by setting one or more secondary numbers for the user. Provides users with the ability to have multiple MSISDN numbers. According to various situations and scenarios, users can choose a number as the current external contact number at any time when initiating a call, without being limited by time and space; and the process of user selection is simple and fast, without the need for network switching and complicated menu operations , which can cope with frequent switching situations. At any moment, all the numbers of the user (primary number and secondary number) are in the state of being able to receive incoming calls, and there is no need to use services such as forwarding, voice mail, and the resulting additional fees.

In addition, for the operator, the user needs to apply for this service from the operator, so that the operator can flexibly control and provide the ability to provide additional services. For example, the operator can combine the main number and the secondary number to provide special discount bundles, charge monthly service fees, and set the default selection of the secondary number according to the calling location.

Furthermore, when the user who uses the secondary number calls the other party for the first time, he creates initial authorization information for the called party, and when the authorized user calls the secondary number, the process of authenticating it completes the system authentication mechanism, thereby It prevents the user number information from being maliciously disseminated and receiving a lot of harassment.

Only the call of the user who has applied for this service will trigger the intelligent network, so the additional network overhead is small.

Detailed ways

The core of the present invention is to set one or more secondary numbers for the user and correspond to different dialing modes respectively, and realize providing multiple MSISDN numbers for the user on a mobile phone by means of the conversion of the intelligent network. When the user initiates a call, The system will display the number corresponding to the dialing method to the called party, and when other users call the user's secondary number, the system will continue according to the primary number corresponding to the secondary number, and add an access code before the calling number. .In order to further protect the user from malicious harassment, when other users call the user's secondary number, the system authenticates the calling user.

In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

With reference to Fig. 3, Fig. 3 has shown the realization process of the first embodiment of the method of the present invention, comprises the following steps:

Step 301: Set one or more secondary numbers and dialing methods corresponding to each secondary number for the user.

When the service operator provides this service for the user, the user can apply by telephone, or WWW web page, or short message, or wireless application protocol/general packet radio service, etc., and the number of secondary numbers can also be based on the user's Need to set.

Step 302: When the user initiates a call, the user displays the number corresponding to the dialing method to the called party.

Users using this service can determine the calling number to be displayed to the other party through different dialing methods when initiating a call. Using the dialing method of "access code" + "called number", a secondary number corresponding to the dialing method will be displayed on the called party, and the dialing method of directly dialing the "called number" will be displayed on the called party. The user's primary number.

The call triggers the intelligent network, and the intelligent network selects the corresponding number from the database according to the access code before the called number, and modifies the calling number displayed externally through signaling.

For example, the user's main number is 11111, the two secondary numbers are 22222 and 33333 respectively, and the corresponding access codes are 95 and 96 respectively. When the user calls with his familiar friends, he can use the main number, which is the same as the existing normal dialing process; when the user communicates with certain industries, he can use the secondary number 22222, and dial 96 before the called number when dialing At this time, the system makes the other party's mobile phone or PHS or a fixed-line terminal with caller ID display the user's secondary number 22222.

Step 303: When other users call the user's secondary number, connect according to the primary number corresponding to the secondary number, and add an access code display before the calling number displayed on the user's phone.

According to the information stored in the database, the intelligent network judges whether the caller is the main number or the secondary number of the user. If it is the main number, the intelligent network instructs the switch to connect directly, and the switch can follow the normal process to use the number to the user's HLR (home location). Register) address to MSRN (Mobile Subscriber Roaming Number) for connection. If it is a secondary number, the intelligent network will query the user's primary number according to the information stored in the database, instruct the exchange to connect according to the primary number, and at the same time add an access code before the calling number to indicate that the other party is calling the secondary number. Number. The exchange can follow the normal process to address the user's HLR with the main number to MSRN for connection, and the caller can know that the other party is calling a secondary number through the access code before the caller ID, so that the user can handle the call flexibly .

The telephone call flow in the present invention will be described below by taking a mobile telephone network with intelligent network capability as an example.

When the service user is the calling party, if the user uses the main number to make a call, its MSISDN number will be sent to the called user and displayed on the called user's terminal. This call does not require the participation of the intelligent network, and it is the same as the outgoing process of a traditional mobile phone. If the user uses any secondary number to dial the called user, the call flow is as follows:

(1) Business user A dials local phone user B in the way of "access code" + "called number" and dials "9512345", where "95" is the access code corresponding to the secondary number "22222" and "12345" is the actual phone number of user B.

(2) The MSC (Mobile Switching Center) reports the call to the SCP according to the access code "95".

(3) The SCP queries its database to check whether the calling user A is a registered user of the service. If it is a non-registered user, it sends a voice prompt message to the calling user and releases the call; Obtain the secondary number currently used by user A, instruct MSC to connect to called user B, and send the secondary number "22222" of user A to MSC as the calling number.

(4) The MSC connects to the called user B according to the new calling number, and connects the call. The calling number displayed on the terminal of the called user B is "22222".

When the service user is called, if there is an incoming call, the call processing process when other user C dials the main number of the service user A is the same as the traditional mobile phone process, and will not be described in detail here. Assuming that user B dials the secondary number "22222" of user A in this service, the call flow is as follows:

(1) MSC/VLR/SSP (Mobile Switching Center/Visitor Location Register/Service Switching Point) sends inquiry information to SCP after receiving a call initiated by a PSTN (Public Switched Telephone Network) user or a mobile user.

(2) After the SCP receives the query information, it queries the user information stored in the database according to the secondary number, returns the MSISDN of the primary number corresponding to the number, and sends a connection message to the MSC/VLR/SSP at the same time.

(3) The MSC connects according to the traditional call flow of the mobile network.

(4) After the call ends, either the calling party or the called party hangs up, and the MSC/VLR/SSP reports the hang-up event and the charging report to the SCP.

(5) The SCP instructs the MSC/VLR/SSP to play the message "Called Power Off" to the calling party.

In a fixed telephone network with intelligent network capabilities, the telephone call flow of the present invention is similar to the above, and will not be described in detail here.

In order to effectively avoid unnecessary harassment for users, the user who calls the secondary number can also be authenticated.

With reference to the implementation process of the second embodiment of the inventive method shown in Figure 4:

Step 401: Set one or more secondary numbers and dialing methods corresponding to each secondary number for the user.

By applying for multiple numbers, the user can make his phone terminal have the function of "one machine with multiple numbers". For mobile phone terminals, when using different numbers to call, it is no longer necessary to replace the SIM card, the information of the user's main number and each auxiliary code All are stored in the system database that provides this service to users. The way to apply for this service has been described in detail above, and will not be repeated here.

Step 402: When the user initiates a call, the user displays the number corresponding to the dialing method to the called party.

The service user can use the main number to call out, so that when the user calls out, the main number will be sent to the called user and displayed on the called user's terminal. This call is the same as the usual phone call out process. At the same time, users of this service can also use any secondary number to dial the called party, that is, use the dialing method of "access code" + "called number" mentioned above to realize the call out. The call triggers the intelligent network, and the intelligent network selects the corresponding number from the database according to the access code before the called number, and modifies the calling number displayed externally through signaling.

Users may need to prevent their phone numbers from being maliciously spread, so as not to be disturbed too much. At this time, when the user uses the dialing method corresponding to the secondary number to call the called party for the first time, the system can create initial authorization information for the called party:

The system automatically records the called number and generates a digital password at the same time, at this time the other party's phone can see the secondary number. The system can send the generated digital password to the service user by text message or voice. After the call is connected, the user will inform the called party of the received password information; The generated digital password is sent to the called party, so as to realize the authorization of the other party.

In order to further prevent the password and the service user number from being maliciously spread together, the system can simultaneously generate a limit on the number of incoming calls allowed for the password. The number of allowed incoming calls can be generated by the system according to preset settings; it can also be set by the user, that is, the system sends voice prompt information to the service user, and the user inputs according to the voice prompt. When other users who call the number of this service user use up the number of incoming calls due to reasons such as password input errors, the password will automatically become invalid.

In this way, the authorization to other users is realized, and for unauthorized users, the number cannot be dialed.

Step 403: When other users call the user's secondary number, authenticate the calling user.

When other users call a certain secondary number of the user, the intelligent network queries the internal database, and if the number has been in contact with the user for many times (for example, a minimum number of times can be set in advance), it is determined that the calling number of the other party is the original user. The other party's number at the time of authorization can decide not to require further password prompt authentication, and directly enter the subsequent connection process. If the incoming call number is an unfamiliar number, or even an authorized number requires password authentication (for example, the user has only kept in touch with the authorized user temporarily), at this time, the system will play a prompt tone that requires password input to the other party, and according to The password entered by the other party to determine whether it is an authorized authorized user. If the system receives that the password input by the calling user is correct, it enters the subsequent connection process; otherwise, it releases the call.

If a limit on the number of allowed incoming calls is set, before the system plays a prompt tone requiring a password to the calling user, it needs to determine whether the number of allowed incoming calls of the calling user has been used up, and if it has been used up, it must be released. This call.

Step 404: After passing the authentication, connect according to the primary number corresponding to the secondary number.

In order for the service user to know clearly whether the other party is calling the user's primary number or the secondary number, after other users call the user's secondary number and pass the authentication, the user's phone will display "access code" + " calling number".

With reference to Fig. 5, Fig. 5 is the structural representation of system of the present invention:

The system that the present invention adds the special-purpose number for the user comprises:

The mobile phone network and/or the fixed phone network S0 and the "one machine with multiple numbers" service platform S1, database S2, authentication server S3, mobile terminal S4 and/or fixed network terminal S5 set up in the network and connected to each other, and the home location Register S6. Among them, the service platform is the core control device of the service, which communicates and interacts with the switch or service switching point in the network through inter-office signaling, so that when the service user answers an incoming call or initiates a service call, it connects the call; the database It is used to store the landline main number or PHS main number or mobile phone MSISDN number of the service user and the corresponding secondary numbers, user registration information, and setting information of the calling number for query and conversion of relevant information and numbers ; The authentication server is used to authenticate the user who calls the secondary number of the service user.

The mobile telephone network and/or the fixed telephone network may be a Global System for Mobile Communications GSM network, a Code Division Multiple Access CDMA network, a PHS network, and a public switched telephone network PSTN, etc.

At present, because most of the communication networks have intelligent functions, the system of the present invention can be set in the existing intelligent communication network, so that the service platform and the database can be integrated in the service control point SCP of the intelligent network, and the SCP and The inter-office signaling for the service switching point SSP of the intelligent network or the switch of the non-intelligent network to communicate and interact is the intelligent network application protocol INAP or the CAMEL (client application of mobile network enhanced logic) application protocol CAP or the wireless intelligent network protocol WIN.

In the following, the service call flow will be further described in detail in combination with the cooperation between the system and the GSM/WCDMA (Global System for Mobile Communications/Wideband Code Division Multiple Access) network (using the CAMEL smart protocol).

Refer to the flow chart of the service user initiating an outbound call shown in Figure 6:

1. The mechanism that HLR and VLR cooperate to maintain the MSISDN of each mobile subscriber remains unchanged at ordinary times. When the user (the calling party and the called party are the same) turns on the phone and updates the location, the VLR of the current network obtains the MSISDN from the HLR, and the HLR records the user's current network location and returns the MSISDN, which is stored in the VLR.

2. The calling user initiates a call, uses the access code to call the called party, and hopes to display his secondary number to the other party.

3. The network pre-registers the CSI (CAMEL subscription information) that marks the user's intelligent service, or triggers the information of the intelligent network according to the specified access code. According to the CSI data or access code trigger data of the calling user, the calling office switch learns that the calling user uses the intelligent service, then the calling office switch sends an IDP ( Initial detection point) message, triggering the intelligent process to the intelligent network; thereby establishing the control relationship between the calling office switch and the intelligent network, wherein the IDP message sent by the calling office switch contains the calling user applying for the intelligent service Number (main number and secondary number) and called party number information. After processing and receiving the IDP message, the SCP queries the intelligent service information related to the intelligent service applied by the calling user according to the calling user number and called user number applying for the intelligent service in the IDP message and the database information registered in the SCP. Then run the corresponding smart business logic according to the obtained smart business information.

4. If the intelligent network also wants the calling office exchange to report various events encountered in the call connection process (such as the called party is busy, the routing connection fails, the calling party abandons the event, etc.), so that the calling office exchange can When performing routing connection processing (such as the calling user releases the call and performs rerouting, etc.), RRBE (request report BCSM event, basic call state model event request report) can be sent to the SCP in sequence. By sending the RRBE message, the intelligent network configures items that the calling office switch is expected to report corresponding events.

5. Intelligent business logic judges that if this is the first call to the called user, and because there is an access code, the secondary number needs to be displayed externally, and it may be necessary (according to the information set by the user or operator in the intelligent network) to call The incoming call of the secondary number is authenticated, and then authorization processing is performed. The system automatically generates the corresponding password and the number of times allowed to call in, or sends CTR (ConnectToResource) as shown in the figure to start voice interaction with the user to realize information customization with user participation.

6. The intelligent network system issues P&C (PromptAndCollectUserInformation), plays the corresponding voice and prompts the user to input information. The switch collects user input and reports (P&C ack, not listed in the figure) to the intelligent network SCP. Through the interaction between the intelligent network and the user, the user can set whether to perform incoming call authentication on the called party, assign a password and the number of times the password can be used, and so on. Multiple interactions are possible.

7. The SCP in the intelligent network sends a connect message, wherein the connect message includes the called number and the calling number. According to the access code dialed by the caller, the SCP fills in the corresponding secondary number information in the caller number information in the message, removes the prefix from the called number dialed by the caller, and fills in the called number information in the message In the calling number, it is convenient for the network to route correctly and display the customized calling number. It can be seen that compared with the existing network processing, the present invention adds the process of changing the calling number and completes the function of displaying the secondary number to the outside.

8. The switch performs routing connection according to the above information. If the called number is the mobile number of this network, it needs to be obtained from the called HLR according to the normal process.

9. Obtain the called MSRN.

10. Use MSRN for routing connection, and the two parties talk.

11. When an abnormal event occurs during the call continuation process or a call end event occurs (such as when the calling party hangs up the event), if the intelligent network configures this event in the RRBE message, the calling office switch will report the ERB (Basic Call state model event) message to the SCP, so as to report the relevant events encountered to the intelligent network SCP.

12. After receiving the ERB message reported by the calling office switch, the SCP judges that the call has ended, sends a Release Call (ReleaseCall) message, and notifies the calling office switch to release the current call control with the intelligent network.

Refer to the flow chart of other users calling this service user as shown in Figure 7:

1. Normally, the mechanism of HLR and VLR cooperating to maintain the MSISDN of each mobile user remains unchanged. However, it is necessary to trigger the information of the intelligent network when registering the CSI information of the intelligent service for the secondary number applied by the user in the HLR in advance, or registering the secondary number of the specified number range in the MSC. This process is equivalent to the process of configuring subscription information for an independent user on the live network. Refer to Figure 6 for this step, which is not shown in this figure.

2. When the calling user initiates a call, the calling office switch first learns that the called user applies for an intelligent service based on the CSI data of the called secondary number, or that the secondary number belongs to the range that needs to trigger the intelligent network. Then the calling office exchange sends an IDP (initial detection point) message to the service control point SCP to which the called secondary number belongs according to the intelligent call processing flow, triggering the intelligent process to the intelligent network; thereby establishing a connection between the calling office exchange and the intelligent network. control relationship between them. The IDP message sent by the calling office exchange includes the calling party number of the incoming call and the secondary number information of the called party who has applied for the intelligent service.

When the SCP processes the received IDP message, it queries the smart service information related to the smart service applied by the called user according to the secondary number and caller number in the IDP message and the database information registered in the SCP, and then according to The obtained smart business information runs the corresponding smart business logic.

3. If the intelligent network also wants the calling office switch to report various events encountered in the call connection process (such as the called party is busy, the routing connection fails, the calling party abandons the event, etc.), so that the calling office switch can When performing routing connection processing (such as the calling user releases the call and performs rerouting, etc.), RRBE (request report BCSM event, basic call state model event request report) can be sent to the SCP in sequence. By sending the RRBE message, the intelligent network configures items that the calling office switch is expected to report corresponding events.

The processing process of the above step 1 to step 3 is the same as the processing process of the live network.

4. Intelligent service logic judges that if this is a call to a secondary number, and possibly (according to the information set by the user or operator in the intelligent network) the incoming call needs to be authenticated, then authentication processing is performed. By comparing the identification of the calling number with the previously set authorization information, it is decided whether to perform password authentication. If password authentication is required, the system sends (CTR, ConnetToResource) to start voice interaction with the user to realize the interaction with the calling user. This is to realize the function of avoiding malicious harassment of secondary numbers.

5. The intelligent network system issues (P&C, PromptAndCollectUserInformation), plays the corresponding voice and prompts the calling user to input information.

6. The switch collects the caller's input and reports (P&C ack) to the intelligent network SCP. The intelligent network matches the password and checks the corresponding number of calls, and if it succeeds, it enters the follow-up process. Otherwise, go to step 9 below to release the call.

7. The SCP sends a connect message. According to the secondary number dialed by the calling party, the SCP fills in the corresponding access code in the calling number information in the message, and replaces the called number dialed by the calling party with the main number of the called user, so that the network can correctly Routing and display of customized calling numbers.

8. The switch performs routing connection according to the above information. Since the called party is a mobile number of the local network, it is necessary to obtain the called MSRN from the called HLR first according to the normal process, and then perform routing connection.

9. When an abnormal event occurs in the call continuation process or a call end event occurs (such as when the calling party hangs up the event), if the above-mentioned intelligent network configures this event in the RRBE message, the calling office switch will report the ERB (Basic Call state model event) message to the calling office switch to report the relevant events encountered to the intelligent network SCP.

10. The SCP sends a release call (ReleaseCall) message to notify the calling office switch to release the call. If the call is not allowed to be connected due to authentication failure, the corresponding reason value is filled in the message to instruct the network to play the specified error prompt tone.

Above-mentioned with the example of GSM/WCDMA network and corresponding CAMEL agreement, the call flow in the system of the present invention has been described in detail, the present invention is not limited to the network in this embodiment, is equally applicable to all can sign up for the user intelligent service information, or The number that can specify the number segment triggers the intelligent network network of the intelligent network, including the circuit domain, the packet domain, and the IMS (International Mobile Subscriber) network. The system of the present invention can provide multiple external contact numbers for a user number, can authorize and authenticate incoming calls, and can enable the service user to know which number the other party uses to call his related services.

While the invention has been described by way of example, those skilled in the art will appreciate that there are many variations and changes to the invention without departing from the spirit of the invention, and it is intended that the appended claims cover such variations and changes without departing from the spirit of the invention.
