Description

Method and device for displaying communication number

technical field

The invention relates to communication technology, in particular to a method and device for displaying communication numbers.

Background technique

At present, with the intelligentization of terminals and switches, mobile communication terminals have the service of displaying the number of the sender. This service is used to prevent illegal violence and harassing calls generated by the phone, and has information to protect the sender, that is, to hide the sender. The function of the number, this service is to give the recipient a priority service. That is to say, usually when making a call, your own phone number is displayed on the recipient terminal, but when dialing, attach a specific identification code (for example: *23#) The sender's number is not displayed on the machine. In other words, before entering the recipient's phone number (example: 019-491-3118) on the standby screen of the terminal, you can make a call by entering a specific identification code (example: *23#) in advance, and you can hide the transmission. party number.

However, the above method is only applicable when the sender remembers the receiver's phone number. In the case that most users dial after inquiring the telephone directory, in order to hide the sender's number, they must also write down the above-mentioned telephone number that has been inquired before inputting, so there is inconvenience; otherwise, in the telephone directory After querying the receiver's phone number on the Internet and dialing directly, there is a problem that the sender's number cannot be hidden.

In addition, from the point of view of the recipient of the call, the terminal itself does not have a method of refusing to answer the call that does not display the number of the sender, and in fact it only relies on the service of the carrier. That is, the terminal itself cannot display the phone number of the sender, because there is no way to induce the display of the number of the sender, so there is a disadvantage that all calls that do not display the number of the sender must be answered.

In addition, the number hiding service has been disclosed in the standard supplementary service, that is, the user does not need to display the number on the called terminal when calling. This is set by whether the caller ID service of a mobile station international ISDN number (ie MSISDN, Mobile Station international ISDN number) is opened in the home location register (HLR, Home Location Register); if the "caller ID" is opened, then The calling party's phone number can be displayed, but the calling party's number cannot be hidden; if the "Caller ID" is not enabled on the HLR, although the calling party's number can be hidden, but because the called party cannot see the calling party's incoming call number, you cannot call back based on the caller ID.

It can be known from the technical solution disclosed above that although the method can hide the calling user's number by setting the HLR, since the called party cannot see the calling party's caller ID, it cannot call back according to the caller ID. Therefore, The calling party still needs to announce its own number to be called. That is, when answering or making a call, one cannot effectively hide one's own phone number.

Contents of the invention

The technical problem solved by the present invention is to provide a method and device for displaying communication numbers, so as to solve the problem that users cannot hide their real numbers when dialing and answering calls in the current technology.

In order to solve the above problems, the present invention provides a method for displaying a communication number, the method comprising the steps of:

A. Set the corresponding relationship between the real number of the SIM card and the virtual number at the service control point;

B. The service control point automatically hides or converts the user's calling number into a virtual number according to the way the user dials the called number, and then connects, specifically including: when the user dials the called number by <called number>*n , if multiple virtual numbers are set, the service control point obtains the virtual number corresponding to the user by analyzing the dialed called number, and connects it as the calling number, wherein the <called number >*n means that the user wants to use the virtual number n as the calling number to call the called number to be dialed.

The corresponding relationship is: one real number corresponds to one or more virtual numbers.

The corresponding relationship between the virtual number and the called number is also set at the service control point, and the one virtual number corresponds to one or more called numbers.

The corresponding processing of the calling number specifically includes: displaying different caller IDs for the called real number according to the difference of the virtual number dialed by the calling number.

The service control point sends the connection operation, and carries the hidden or converted real calling number through the general number parameter.

Step A also includes: setting different connection processing modes for each called virtual number in the service control point, and performing call control processing according to the different connection processing modes.

The different connection processing methods of the called virtual number include: normal connection, direct release of the call, playing busy tone and playing fixed-value voice prompts.

If the virtual number is the international ISDN number of the mobile station normally allocated by the operator, the mobile switching office triggers the intelligent network service control point by configuring the user application user subscription information data of the mobile network enhancement logic;

If the virtual number is an international ISDN number of the mobile station abnormally allocated by the operator, the service control point converts the calling number into a virtual number and adds an access code prefix before the virtual number when the user uses the virtual number as a calling party;

If the virtual number is an abnormal mobile phone number, it is necessary to make an access code at the mobile switching office to trigger the trigger data of the intelligent network service control point.

The method also includes the steps of:

C. When the user uses the virtual number as the called number to call back, the service control point retrieves the corresponding relationship between the received virtual number and the real number, obtains the real number and continues the call, and calls The number is processed accordingly.

If the called user uses the virtual number prefixed with the access code to call back, the mobile switching office will use the access code to trigger the service control point of the intelligent network.

In addition, the present invention also provides a device for hiding the network calling number, the device comprising:

The setting unit is used to set the corresponding relationship between the real number and the virtual number of the SIM card, and one real number corresponds to one or more virtual numbers;

The conversion unit is connected with the setting unit, and is used to convert the user’s calling number into a corresponding virtual number or hide it according to the way the user dials the called number, specifically including: when the user passes the <called number> *When dialing the called number in n mode, if there are multiple virtual numbers, the virtual number corresponding to the user is obtained by analyzing the dialed called number, and connected as the calling number, wherein the < Called number>*n indicates that the user wants to use the virtual number n as the calling number to call the called number to be dialed.

The device also includes:

The retrieval processing unit is connected with the conversion unit, and is used to retrieve the corresponding relationship between the virtual number dialed back by the called user and the real number, to continue the call after obtaining the real number, and to perform corresponding processing on the calling number.

The setting unit also includes:

The virtual number setting subunit is used to set the corresponding relationship between the virtual number and the called number, and one virtual number corresponds to one or more called numbers;

The call control processing subunit is connected with the virtual number setting subunit, and is used to set different connection processing methods according to each called virtual number, and perform corresponding call control processing according to the different connection methods of each virtual number.

The different connection processing methods of the called virtual number include: normal connection, direct release of the call, playing busy tone and playing fixed-value voice prompts.

It can be known from the technical solutions disclosed above that the present invention provides privacy protection for user numbers by hiding or changing the user's identity, so that the user will not disclose his own number when making and receiving calls. That is to say, the calling user can hide the real number from the called party, and display different calling number IDs to different called parties. When being called, the caller ID can indicate which number the caller is dialing, and the call can be handled differently according to different called numbers. In addition, it is also possible to set different connection processing methods for the called number, such as: setting an empty number, playing a busy tone, playing customized voice prompts or connection, etc. The scheme of the invention changes the user's number, hides the real number of the user, and can provide enhanced value-added services of the non-disturbing type to big customers.

Detailed ways

The core of the present invention is: use the call control capability of the service control point (SCP, Service Control Point), hide or convert the calling number, and display the converted virtual number to the called; and identify the called number, correctly Connect to the real mobile station international ISDN number (ie MSISDN, Mobile Station international ISDN number) or mobile phone number corresponding to the virtual number. In addition, the present invention can also utilize the call control capability of the SCP to identify calls after number hiding/converting, and perform value-added service control on such calls. For example, customized processing (such as connection, announcement prompt, direct cut-off, etc.) is performed on calls dialed from different virtual numbers; different virtual calling numbers are displayed according to the called number. In this way, privacy protection is provided for user numbers, so that users will not disclose their own phone numbers when making or answering calls.

In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings.

Please refer to FIG. 1 , which is a flow chart of the method for displaying communication numbers in the present invention. The method comprises the steps of:

Step S11: setting the corresponding relationship between the real number and the virtual number of the SIM card at the service control point;

Step S12: The service control point automatically hides or converts the user's calling number into a virtual number according to the way the user dials the called number, and then connects.

The method may also include:

Step S13: When the user uses the virtual number as the called number to call back, the service control point retrieves the corresponding relationship between the received virtual number and the real number, obtains the real number and continues the call, and checks the calling number Deal with it accordingly.

The scheme of the present invention is to bind a Subscriber Identity Module (SIM, Subscriber Identity Module) card with the original mobile phone number, and then bind one or more other numbers through the intelligent network, wherein the number can be The mobile phone number can also be a virtual number, etc.; users can use different numbers in different occasions according to their needs, especially after the participation of the intelligent network, it can realize the functions of prohibiting the connection of some numbers in specific scenarios and displaying different prompt information on the user terminal. When the user makes a call, he can log in to the portal website (Portal) through various means in advance to set the number hiding/changing principle, and can also enable number hiding/changing for a single call through a special dialing method. When the user is called, that is, when other users dial the converted virtual number, the user can still get through after the SCP number is converted, but the special caller ID is used to distinguish, and the user can choose whether to answer or not. Specifies the default handling of calls dialed to the converted number. For example, report empty number, play busy tone and connect, etc. That is, according to the system configuration, different virtual numbers can be used for different called numbers; it is also possible to know which virtual number the calling user is dialing according to the difference in the calling number of the caller ID. Its specific implementation process is:

In step S11, the user can set the corresponding relationship between the real mobile station international ISDN number (MSISDN) of the user SIM card and the virtual number at the service control point SCP, and a real MSISDN can correspond to one or more virtual numbers; The relationship between the virtual number and the called number can be set in the SCP through a portal (Portal), and one virtual number can correspond to one or more called numbers.

And in step S12, the service control point automatically hides the calling number of the user or converts the virtual number according to the way the user dials the called number, and then connects. Wherein, the way that the user dials the called number mainly includes two kinds: one is, when the user directly dials the called number, if only a virtual number is set, the service control point SCP automatically converts the calling number into The corresponding virtual number may be hidden and then connected; the other is that when the user dials the called number through a special dialing method, if multiple virtual numbers are set, the service control point SCP analyzes the dialed called number , obtain the virtual number corresponding to the user, and connect it as the calling number. That is to say, the user can enable different virtual numbers as the calling party through a special dialing method. For example, the user dials <called number>*n, if n is 1, it means that the user requests to use virtual number 1 Call the called number he wants to dial as the calling number; when the SCP analyzes the called number dialed by the user, obtains the virtual number corresponding to the called number of the user is No. 1, and then uses the virtual number 1 as the calling number The number is connected to the called party. That is, the calling party's number displayed on the called party is virtual number 1. However, the present invention is not limited to the two disclosed methods, and may also include other methods of dialing the called user.

Wherein, in the above conversion or hiding process, when the user dials the comparison number, the MSC of the mobile end office sends the user's calling number to the service control point SCP by initiating a detection point (IDS) request message; the SCP receives the After the request message, by analyzing the virtual number corresponding to the called number dialed by the user, the Connect operation signaling is issued. The content of the signaling includes: calling number parameters and called number parameters, as shown in Table 1.

Table 1

The SCP hides or converts the real number of the caller by modifying the Generic Numbers (calling number) parameter; Put it in the Generic Numbers parameter and send it to the MSC, and the MSC will display the calling number of the caller ID as the number in the Generic Numbers. In the connect operation, the Destination Routing Address parameter is the called number. The specific sequence diagram of its realization process is shown in Fig. 2 .

When other users use the virtual number as the called number to call back, the virtual number triggers the SCP, and the SCP retrieves the corresponding relationship between the virtual number and the real number in the database, obtains the real number, connects the call, and checks the calling number Processing is performed, that is, different caller IDs are displayed for the called real number according to the difference of the virtual number dialed by the calling number. For example, when a user dials <virtual number 1>, the SCP first retrieves the real number corresponding to the virtual number 1, and after obtaining the real number, performs number conversion, and displays the caller ID to the called party as: <calling number>*1 , indicating that the calling party dials the first virtual number of the called party to make a call (step S13).

In addition, the present invention can also set different connection processing methods for each called virtual number at the service control point SCP through the portal website Portal. When a user calls, the SCP can perform call control processing according to the different connection methods of each virtual number . Among them, the different connection processing methods of the called virtual number usually include: 1. Normal connection; 2. Direct release of the call; 3. Playing busy tone; 4. Playing customized voice prompts, etc., but not limited to the currently disclosed ones, Other connection processing methods may also be included. For easy understanding, please refer to the following example: Assuming that the user sets the connection processing method of the virtual number 1 in the SCP as "4. Play customized voice prompts", then when the calling user dials the virtual number, the SCP will make an error according to the setting. The call is connected, but a voice prompt or playback is given to the caller (the content of the playback is provided by a voice file and can be recorded).

In the implementation process of the present invention, the virtual number refers to the normal MSISDN number assigned by the operator, that is, the SCP that can trigger the intelligent network. However, if the virtual number is a non-MSISDN number allocated by the operator (such as a fixed network PSTN number), the SCP needs to add an access code prefix when converting or hiding the number, so that the fixed network PSTN uses the access code to trigger the intelligent network. The service control point SCP. When the called party uses this number to call back, the mobile switching center (MSC, mobile switching center) will use the prefix of the number to trigger the SCP of the intelligent network through the access code. The following process is the same as the present invention, and will not be repeated here. .

In addition, the present invention also provides a communication number display device, which can be located in the service control point or in other places. The schematic diagram of the structure of the device is shown in Figure 3. The device includes: a setting unit 11 , a conversion unit 12 and/or a retrieval processing unit 13 . Wherein said setting unit 11 is used to set the corresponding relationship between the real mobile station international ISDN number and the virtual number of the SIM card and the virtual number and the called number; the conversion unit 12 is connected with the setting unit 11 for use After converting the user's calling number into a corresponding virtual number or hiding it according to the way the user dials the called number, the connection is carried out; the retrieval processing unit 13 is connected with the conversion unit 12, and is used to retrieve the call-back information of the called user. The corresponding relationship between the virtual number and the real number, after obtaining the real number, the call is continued, and the calling number is processed accordingly.

Wherein, the setting unit 11 also includes: a call control processing subunit 111 and a virtual number setting subunit 112, the virtual number setting subunit 112 is used to set the corresponding relationship between the virtual number and the called number, a virtual number Corresponding to one or more called numbers; the call control processing subunit 111 is connected to the virtual number setting subunit 112, and is used to set different connection processing methods according to each called virtual number, and to set different connection processing methods according to each virtual number. corresponding call control processing. The different connection processing methods of the called virtual number include: normal connection, direct release of the call, playing busy tone and playing fixed-value voice prompts. However, it is not limited to these disclosed connection processing methods, and other methods may also be included.

Please refer to the implementation process of the above-mentioned method for the implementation functions of each unit of the above-mentioned device, and details will not be repeated here.

Now combine an application example to better illustrate the present invention.

Please refer to FIG. 4A and FIG. 4B. FIG. 4A is a schematic diagram of the calling party choosing to hide or change the number according to the present invention, and FIG. 4B is a schematic diagram of the present invention to connect the called call through the converted number. Its specific implementation process is:

As shown in FIG. 4A , it includes a calling terminal and a called terminal, and the calling terminal and the called terminal are connected through the Internet. The calling terminal includes: a user terminal (such as a mobile phone), and a mobile switching center MSC; the called terminal includes: a visited mobile services switching center (VMSC, visited mobile services switching centre), and a called terminal (such as a mobile phone). When a user at the calling end (such as the calling number: 13901012345) dials the called number (such as: 13601013579), the mobile switching office sends the called number of the user to the service control point SCP through CAP signaling, that is, an IDP request message, By analyzing the called number dialed by the user, the SCP hides or converts the calling number according to the preset principle of hiding or converting (that is, converting into a virtual number), and uses it as the calling number to call the called number. To connect, that is, the calling number displayed on the called party is the converted virtual number (for example, 13901067890). It can be seen that this process provides effective privacy protection for the calling number when the user makes a call, that is, the user does not disclose his own number when making a call.

Similarly, when other users dial the changed number (that is, when calling back the virtual number), after the SCP number is also changed, the corresponding virtual number is placed in the Generic Numbers ( calling number) parameter and send it to MSC. The user can still connect to the callback call of the called user. But it can be distinguished through the special caller ID, whether the number is the call that the user wants to answer, if so, it can be answered, otherwise, it can not be answered. In addition, it is also possible to set the default processing method for dialing the converted number (such as setting an empty number, playing a busy tone or continuing). The specific implementation process is shown in Figure 4B, and will not be described in detail here.

In the embodiments of the present invention, the virtual numbers described in the present invention are not limited to MSISDN (i.e. mobile phone numbers), and are also applicable to fixed network PSTN numbers; for fixed network PSTN numbers, SCP needs to use the pair when converting virtual numbers. The method of adding an access code prefix to the virtual number is adapted to use the access code of the fixed network PSTN to trigger the intelligent network service SCP. That is to say, if the virtual number is the international ISDN number of the mobile station normally allocated by the operator, the mobile switching office triggers the intelligent network service control point; if the virtual number is an international ISDN number of the mobile station abnormally allocated by the operator, the service control point will convert the calling number into a virtual number and add Access code prefix; if the virtual number is an abnormal mobile phone number, it is necessary to make an access code at the mobile switching office to trigger the trigger data of the intelligent network service control point. The specific implementation process is described above in detail, and will not be repeated here.

In addition, the technical scheme of the present invention is also applicable to the calling party and the called party simultaneously opening the concealment or conversion service. If both the calling party and the called party open the technical scheme of the communication number display of the present invention, then the number of the calling party/called party can be hidden or converted at the same time, that is, the number displayed at the called party is the number displayed by the calling party. The number is hidden or transformed into a virtual number. At the same time, when the called party calls back, the number displayed on the calling party is also the hidden or transformed number of the called party. Its specific implementation process is the same as the technical solution of the present invention, and will not be described in detail here.

The above is only a preferred embodiment of the present invention, it should be pointed out that, for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications can also be made. It should be regarded as the protection scope of the present invention.
