Description

System and method for realizing calling by using value-added service access code and virtual number

technical field

The present invention relates to a system and method for a telecommunication user to realize a call by using a virtual number composed of a value-added service access code and a virtual number. Specifically, it relates to a mobile or fixed telecommunication network. (For example, mobile station international ISDN number MSISDN (Mobile Station International ISDN Number) of mobile phone users or landline numbers of landline telephones, etc.) Telecom users provide multiple virtual numbers, and users can use these virtual numbers to answer incoming calls or use a certain virtual number A method and system for calling other users. At this time, the caller number displayed by the called user is a certain virtual number or original directory number set by the calling user; it belongs to the technical field of value-added services in telecommunication networks.

Background technique

At present, in the existing telecommunication network, a terminal device usually has only one directory telephone number, including mobile phones, landline telephones and Xiaoling telephones that are only equipped with a Subscriber Identity Module (SIM, Subscriber Identity Module) commonly used now. So; that is to say, there is only one calling number displayed when answering an incoming call as a called party or dialing out a call.

For a user who has a mobile phone with a SIM card, if he (or she) wants to have multiple numbers at the same time, he or she must buy multiple SIM cards, or even need to buy a mobile phone that can insert multiple SIM cards at the same time. Adopt the method for changing SIM card to make a call, use very inconvenient; And purchase new-type mobile phone, invest expensive again.

At present, there have been some technical solutions of "one phone with multiple numbers" for mobile users in the market, all of which can realize the business function of "only need one SIM card, and have multiple phone numbers at the same time"; the technical means adopted are roughly There are two categories, but both have some limitations. The following are brief descriptions respectively:

Solution 1: Using the mobile intelligent network technology, after corresponding conversion of the calling or called MSISDN, instruct the service switching node SSP (Service Switching Point) to complete the subsequent service processing. This solution requires corresponding technical transformation of the current network equipment. For example, the home location register HLR (Home Location Register) needs to add the record of the new MSISDN number, and the service implementation period is long.

Solution 2: Intercept the original MSISDN number of the calling or called from the mobile switching center MSC, then judge and translate the number in the number service system, and then forward it to the HLR. This solution will involve all calls, the operation is cumbersome, and the connection time is long; even the calls of non-service users need to be intercepted and judged from the switch.

In addition, the above two solutions will occupy MSISDN number resources, which will affect the original MSISDN numbering plan. And, for fixed network or PHS user, still do not have " one machine multiple numbers " realization method at present.

(2) The newly added virtual number does not involve functions such as access authentication, roaming location management, cell switching, and call control of the same mobile phone user, and all these mobile phone functions are still maintained and realized through the user's original MSISDN number; and, With the system's number management function, users can activate or deactivate any number.

(3) All numbers of the user (including original directory numbers and newly added virtual numbers) can be used at the same time. When the call is made, the user can select the calling number by voice prompt or other methods, so that the selected calling number will be displayed on the called user's mobile phone.

(4) Flexible billing: For different numbers of the user, the user can choose to bill separately or charge the bill on one number, such as the original number of the user.

The realization of the present invention will bring win-win for telecommunication users and telecommunication network operators, wherein the benefit to telecommunication is: telecommunication users can use existing terminal equipment, needn't buy new telephone set or SIM card; Different phone numbers of a virtual number can tell different groups of people, such as: colleagues, customers, friends, family members, etc.; you can also choose and set the time to receive calls from different groups of people. Benefits for network operators: Once they have multiple numbers, telecom users will be more willing to tell others their numbers, and they can keep their phones on all the time. This will naturally increase the traffic volume and bring more benefits to the network operator. Enterprises are more willing to equip employees with mobile phones because they can bill the original number and the additional virtual number separately. This will also increase the traffic volume and bring higher benefits to network operators.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

The system for telecommunication users to use virtual numbers based on value-added service access codes to make calls in the present invention consists of a mobile telephone network and/or a fixed telephone network and a service support device for "telecom users use virtual numbers to realize calls" set in the network system , mobile terminal and/or fixed network terminal, the service support device is composed of a "one machine with multiple numbers" service platform, database and billing server connected to each other as the core control device of the service; The inter-office signaling TUP or ISUP or INAP/CAP or WIN communicates with the switch or service switching point in the network, so that when the service user answers an incoming call or initiates a call, it connects the call and generates a call data record CDR; The database is used to store the original directory number of the landline or PHS or mobile phone MSISDN number of the service user and the setting information of each corresponding virtual number, user registration and calling number for query and conversion of relevant information and numbers . Therefore, the present invention realizes the system of "one machine with multiple numbers" service, and does not need to carry out technical improvement or upgrading for each network element equipment of the existing telephone network, and realizes quickly.

The present invention also provides a method for a telecommunication user to use a virtual number based on a value-added service access code to realize a call, which is characterized in that it includes the following steps:

(1) Application and number allocation during use: When a telecom user applies for and registers with the network operator for the service of "realizing calls based on a virtual number based on a value-added service access code" by telephone, text message, WWW web page or in the business hall, he only needs to inform his landline Or PHS or the original directory phone number of the mobile phone, you can complete the business registration and the application of multiple virtual numbers. The operator assigns each virtual number applied for to the service user, and records these numbers in the database of the service support device; the virtual number is composed of the "access code" + "virtual number" of the telecom value-added service.

(2) Activation and deactivation of services: users of this service use telephones, or WWW webpages, or short messages, or WAP/GPRS methods to access the service management system of "realizing calls based on virtual numbers of value-added service access codes", for each The time interval for activation or deactivation of the virtual numbers is set separately, and when any one of the virtual numbers is activated or deactivated, there is no need to shut down the phone; when the call is connected, the switch will analyze the number of the access code dialed in by the calling user to trigger the service. Upgrade the SSP capability of the switching equipment on the network side, which greatly facilitates the deployment and promotion of services.

(3) Incoming call: Other users dial the service user by dialing "access code" + "virtual number" to realize the call; if the virtual number dialed by other users has been closed, the system will play the corresponding message to the user Voice prompts;

(4) Outgoing calls: When making outgoing calls, users of this service can use the method of dialing "access code" + "called number" or set any number including the original directory number and each virtual number as the default The calling number is connected to the user, so that the calling number is displayed as "access code" + "virtual number" or the default calling number, and the called user can directly call back the displayed number;

(5) Flexible billing: when the service user is calling, various fees are charged uniformly according to the original directory number; when the service user is called, the service user can be charged according to the original directory number, or can be charged separately according to each virtual number .

(6) Call screening; users of this service can set black/white lists for their own virtual numbers respectively, where the black list is the area code of the incoming call that is not allowed to call in, and only allows incoming calls from other areas; the white list is the area code that allows call area code of incoming calls, and block incoming calls from other regions to limit or filter incoming calls.

The structural components and implementation methods of the present invention in different telecommunication networks are respectively introduced below.

Referring to Fig. 1, if the existing telecommunication network (fixed telephone network or mobile network) does not have intelligent network conditions, the MSC or switch 4 in it can be connected to the service platform 1, and the scheme of "virtual number + service platform" can be used. The interoffice signaling between platform 1 and MSC or switch 4 is TUP or ISUP. In the figure, 2 is a database, 3 is a billing server, 5 is a mobile terminal and/or a fixed-line network terminal of the service of the present invention, and 6 is other communication terminals.

Taking the telecommunication network shown in Figure 2 as an example, the implementation method of using "virtual number + service platform" in a telecommunication network without intelligent network conditions is introduced. At this time, if there is an incoming call, when other mobile phone terminal user B or fixed-line terminal user C dials the original directory number MSISDN of the service user A, the call processing process is the same as the traditional call-in process:

(a) User B or user C dials the original directory number MSISDN of mobile user A for the "one machine with multiple numbers" service;

(b) Mobile switching center MSC or switch obtains the current roaming number of user A from the user's HLR;

(c) The MSC or switch connects the call to the MSC where user A is currently located according to the roaming number, and connects to user A's mobile phone.

User A in Figure 2 is a "one machine with multiple numbers" service user, and the multiple virtual numbers he owns are: family number 95xxx-11111, friend number 95xxx-22222, and business number 95xxx-33333; assuming that the business number has been closure. The method that other mobile phone terminal user B of the present invention or fixed-line terminal user C calls user A is as follows:

(1) User B dials the official number of user A;

(2) MSC or exchange learns that called A is a service user by identifying the access code "95xxx", and reports the call to the "one machine with multiple numbers" service platform;

(3) The service platform queries the user information stored in the database, and obtains that the current state of the official number of user A is closed;

(4) The service system instructs the MSC or switch to release the call;

(5) Call release. (This kind of call signaling flow that the virtual number of the local incoming call is closed or invalid can be referred to in Fig. 3 - when the inter-office signaling of the mobile network or the fixed-line network uses TUP, or Fig. 4 - when the inter-office signaling of the mobile network or the fixed-line network When ISUP is used for inter-office signaling)

(6) User C dials user A's home number;

(7) MSC or switch learns that the called user is a service user by identifying the access code, and reports the call to the "one machine with multiple numbers" service platform;

(8) The service platform queries the user information stored in the database, and obtains that the current state of the family number of user A is active;

(9) The service platform returns the original directory number MSISDN of user A's mobile phone or the original directory number of the landline or PHS to the MSC or switch, and instructs the MSC or switch to connect the call to "one machine with multiple numbers" according to the number User A's mobile phone or landline or PHS;

(10) MSC or exchange carries out connection according to the above-mentioned traditional call flow of mobile network (i.e. the aforementioned steps a, b, c) or the traditional call flow of fixed-line network, and the call is connected (the signaling flow of this successful call can be found in Figure 5 - when the inter-office signaling of the mobile network or the fixed-line network uses TUP, or Figure 6 - when the inter-office signaling of the mobile network or the fixed-line network uses ISUP).

"One machine with multiple numbers" service users can use the original phone number to make calls, that is, choose to set the original directory number MSISDN or the original directory number of the landline or PHS as the default number, so that when the user calls out, the original directory number will be sent to the called user and displayed on the called user's terminal. This call does not need to be controlled and processed by the service platform in the system of the present invention, which is the same as the usual outgoing call process. At the same time, the service user of the present invention can also use any virtual number to dial the called party, that is, dial out by dialing "access code" + "called number". The call flow is as follows:

(1) Service user A (whose virtual number is "95xxx-11111/22222/33333") dials local telephone user B in the way of "access code" + "called number", where "95xxx" is the receiving number of the service Enter the code, "62281000" is the actual phone number of user B;

(2) MSC or exchange reports the call to the "one machine with multiple numbers" service platform according to the access code "95xxx";

(3) The service platform inquires its database to check whether the calling user A is a registered user of the service, and if it is a non-registered user, then send the voice message of "no right to use this service" to the calling user; if it is a registered user, Then obtain the virtual number currently designated by the user A from the database, instruct the MSC or switch to connect the called user B, and send the service access code + the virtual number of the user A (such as 95xxx-11111) as the calling number to the MSC or switch;

(4) The MSC or the exchange connects 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 95xxx-11111.

The above-mentioned "one machine with multiple numbers" business local outgoing calls and the signaling process of displaying virtual numbers can be referred to Figure 7 (when the inter-office signaling of the mobile network or the fixed line network uses TUP) or Figure 8 (when When the inter-office signaling of the mobile network or the fixed-line network uses ISUP).

If the existing telecommunication network (mobile network or fixed line network) possesses the ability of the intelligent network, that is, when its switch has the service switching point SSP function of the intelligent network, the system of the present invention then uses the scheme of "virtual number+intelligent network" (see Fig. 9 and Fig. 12), that is to say, the "one machine with multiple numbers" service platform 1 and database 2 in the above-mentioned service support device are built in the service control point SCP, and the inter-office signaling for communication and interaction between the SCP and the SSP of the intelligent network They are INAP (for fixed PSTN or PHS network) or CAP (for GSM mobile network) or WIN (for CDMA mobile network). In the figure, PLMN (Public Land MobileTelecommunication Network) is the public land mobile network, HPLMN (Home PLMN) is the home public land mobile network, VPLMN (Visit PLMN) is the visiting public land mobile network, and MSC (Mobile-service Switching Center) is the mobile Switch, GMS C (Gateway MSC) is the mobile switch gateway, HLR (Home Location Register) is the home location register, VLR (VisitorLocation Register) is the visitor location register, SSP is the service exchange point, SCP is the service control point, PSTN is the public exchange telephone network.

Introduce below at first in the mobile phone network that provides intelligent network capability, the telephone call implementation method of " one machine multiple numbers " service of the present invention. At this time, if there is an incoming call, the call processing process when other user B or C dials the original MSISDN number of the service user A is the same as the traditional mobile phone incoming call process;

(a) User B dials the number of mobile user A of the "one machine with multiple numbers" service;

(b) Mobile switching center MSC obtains the current roaming number of user A from the HLR of user A;

(c) The MSC connects the call to the MSC where user A is currently located according to the roaming number, and connects to user A's mobile phone.

In addition, the method of the present invention can realize that the caller dials any virtual number to call the service user of "one machine with multiple numbers". Referring to Fig. 10, it introduces the signaling process of the "one machine with multiple numbers" service call-in in the GSM mobile network, that is, the flow of other users calling a certain virtual number of the "one machine with multiple numbers" service user; assuming that the GSM network already supports mobile The CAMEL (CustomizedApplication for Mobile network Enhanced Logic) capability of the mobile network of the intelligent network is enhanced.

(1) After MSCb/VLR/SSP receives a call initiated by a PSTN user or an ordinary mobile user, and knows that the called user is a service user according to the access code, it sends an IDP message to the SCP of the "one machine with multiple numbers" service.

(2) After the SCP receives the IDP message, it queries the user information stored in the database according to the virtual number in the called number, and judges whether the current state of the virtual number is closed or active. If the current state of the virtual number is off, directly jump to step (6), if the current state of the virtual number is active, perform subsequent steps.

(3) The SCP returns the original directory number MSISDN corresponding to the number, and at the same time sends a connection message to the MSCb/VLR/SSP.

(4) MSCb connects according to the traditional call flow of the mobile network (same as steps a, b, and c above), and the call is connected.

(5) The call stops, and either the calling party or the called party hangs up, and the MSC/VLR/SSP reports the on-hook event and the charging report to the SCP.

(6) The SCP instructs the MSCb/VLR/SSP to play the message "Called off" to the calling party, and hang up.

The user of the "one machine with multiple numbers" service of the present invention can use the original phone number to call out, that is, choose to set the original MSISDN number as the default number, so that when the user calls out, the MSISDN number will be sent to the called user and displayed on the on the terminal of the called user. This kind of call does not need the control and processing of the intelligent network, and it is the same as the outgoing process of the traditional mobile phone. At the same time, the service user of the present invention can also use any virtual number to call the called user, that is, to realize the call out by dialing "access code" + "called number". Taking the GSM network as an example again, assuming that the GSM network has supported the CAMEL capability of the mobile intelligent network, its call flow is illustrated as follows (see Figure 11):

(1) Service user A (whose virtual number is "95xxx-11111/22222/33333") dials local telephone user B in the form of "access code" + "called number", where "95xxx" is the receiving number of the service Enter the code, "136xxxxxxxx" is the actual phone number of user B;

(2) The MSC reports the call to the SCP according to the access code 95xxx;

(3) 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 the voice message of "no right to use this service" to the calling user; Obtain the virtual number currently specified by user A, instruct MSC to connect to called user B, and send the service access code + virtual number of user A (such as 95xxx-11111) 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 95xxx-11111.

Introduce now, in the fixed telephone network that provides intelligent network capability, the telephone call realization method of " one machine multiple numbers " service of the present invention. At this time, if there is an incoming call, the call processing process when other user B or C dials the original directory number of the service user A's landline is the same as the traditional fixed mobile phone incoming call process:

(a) User B dials the original directory number of the landline of fixed user A of the "one machine with multiple numbers" service;

(b) The exchange where user A is located connects the call to user A; user A talks to user B.

In addition, the method of the present invention can realize that the caller dials any virtual number to call the service user of "one machine with multiple numbers". Referring to Fig. 13, it introduces the signaling flow of the "one machine with multiple numbers" business user's incoming call in the fixed-line intelligent network. Number" users have "Family Number" and "Other Numbers". On weekends, turn off "Other Numbers" and turn on "Family Numbers"; the method for other users B and C to call the "one machine with multiple numbers" service user A is as follows:

(1) User B dials the "other number" of user A's landline: 95xxx-22222;

(2) The exchange learns that the called party is a service user by identifying the access code, and reports the call to the SCP;

(3) SCP queries the user information stored in the database, and learns that the current status of the number 95xxx-22222 is closed;

(4) The SCP instructs the exchange to release the call;

(5) Call release.

(6) User C dials the "family number" of user A's landline: 95xxx-11111;

(7) The exchange learns that the called party is a service user by identifying the access code, and reports the call to the SCP;

(8) SCP queries the user information stored in the database, and obtains that the current status of the number 95xxx-11111 is active;

(9) The SCP returns the original directory telephone number of user A's landline obtained through translation to the exchange, and instructs the exchange to connect the call to the landline of user A of "one machine with multiple numbers" according to the number;

(10) The exchange performs connection according to the traditional call flow in the fixed-line network (same as steps a and b above), and the call is connected.

In the present invention, the "one machine with multiple numbers" service user can select the original directory number of the landline to be displayed on the called phone, so that the service user can directly dial the "called number" to call out, and at this time, the control and processing of the intelligent network are not required. Its calling process is the same as that of ordinary landline telephones. At the same time, the service user of the present invention can also use any virtual number to dial the called party, that is, dial out by dialing "access code" + "called number". Assuming that the fixed telephone network already supports the intelligent network capability, the call flow is illustrated as follows (see Figure 14):

(1) Service user A (whose virtual number is "95xxx-11111/22222") dials local telephone user B by means of "access code" + "called number", where "95xxx" is the service access code , "62281000" is the actual phone number of user B;

(2) The MSC reports the call to the SCP according to the access code 95xxx;

(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 message of "no right to use this service" to the calling user; if it is a registered user, then Obtain the virtual number currently designated by the user A from the database, instruct the MSC to connect to the called user B, and send the service access code + the virtual number of the user A (such as 95xxx-11111) to the 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 95xxx-11111.

An innovative feature of the present invention is that different "calling number" displays can be set according to the user's subjective wishes: any number including the original directory telephone number or each virtual number can be designated as the default calling number. When the "one phone with multiple numbers" user calls out, the default number will be sent and displayed on the called user's mobile phone or landline. It is also possible to set different numbers respectively according to different time periods as the calling number, for example, select an official number as the calling number during working hours, and select a family or friend number as the calling number during off-duty hours. It is also possible to set different numbers respectively according to different called numbers as the calling number. For example, when calling a colleague, the official number is selected as the calling number, and when calling a friend, the friend's number is selected as the calling number.

In the present invention, the calling number is set by the service platform or SCP instructing the exchange or MSC to play voice navigation prompts for the service user to select the calling number when calling out, and the specific steps are as follows:

(1) When the service user uses the method of "access code" + "called number" to make a call, the exchange or MSC reports the call to the service platform or SCP according to the access code;

(2) The service platform or SCP instructs the exchange or MSC to play a prompt tone to the calling user, asking the user to select the calling number to make a call;

(3) The service platform or SCP returns the corresponding virtual number as the calling number to the exchange or MSC according to the calling user's choice;

(4) The exchange or MSC takes the virtual number returned by the service platform or SCP as the calling number, connects the call to the called user, and displays the virtual number selected by the calling user on the called terminal.

In the present invention, the setting of the calling number can also be made by the service user through the telephone or WWW web page or short message or WAP/GPRS access operator's "virtual number based on value-added service access code to realize the call" service platform, pre-selected setting Set the calling number sent by it; the selection method is the default setting, or setting according to the time interval, or setting according to the called number. The following are brief descriptions respectively.
