Description

Service triggering method based on original called number information

Technical field

The present invention relates to a called party identification technology of a called terminal in the communication field, and particularly relates to a service triggering method based on original called number information. Background of the invention

Currently, with the rapid development of communication technology and business applications, virtual number services have appeared. In the virtual number service, the operator sets a personal number for the user, and the user associates the personal number with the user's home terminal number, such as a fixed telephone at home; an office terminal number, such as an office fixed telephone; and a mobile terminal number, such as a mobile phone Wait for the list of called terminal numbers to be associated, and store this association in the personal number server. The user can also set the order of these called terminal numbers in the list, for example: the first number is the user's office terminal number, the second number is the user's home terminal number, and the third number is the user's Mobile terminal number.

When the personal number is called, the communication system obtains the stored called terminal number list associated with the personal number from the personal number server, and calls the numbers stored in the list one by one according to the set order. For example: The communication system first calls the user's office terminal number. If the office terminal is not answered or the call is busy within the set time threshold, the user's home terminal number is called. When the terminal in the home is still not answered or the call is busy within the threshold, the mobile terminal number of the user is finally called. During the sequential call of the entire communication system, if any of the called terminals of the user is connected because of the call ringing, such as: the user's office terminal is connected, the call is successfully connected even if the call is successfully connected, The system no longer calls subsequent terminal numbers. The communication system may not care about the order of the called terminal numbers set by the user in the called terminal number list corresponding to a personal number. At this time, when the personal number is called, the communication system obtains the corresponding actual called terminal number from the list according to the personal number and simultaneously calls all corresponding actual called terminals. A user with the personal number can answer any one of them. The called terminal with an incoming call alert completes a simultaneous ringing call.

When the communication system uses a personal number to call a plurality of preset terminals set by the user, there may be a truncation due to the called terminal being mistakenly connected: when the communication system calls the user's preset plurality of called terminals through the personal number When the terminal is called, the called terminal may be cut off by other users by mistake and terminate the call. For example, when a communication system calls a user's office fixed terminal through a personal number, the fixed terminal may be answered by a colleague of the user, and the user is not in the office at this time, which causes the communication system to stop calling in a sequential call. Subsequent called terminal numbers or other called terminals in a simultaneous ringing call end the call and stop ringing, so that the user does not receive the incoming call that should belong to him; when the communication system calls the user's home fixed terminal When the called terminal may be answered by the user ’s family and the user is not at home, the communication system no longer calls the subsequent called terminal number during a sequential call or the user owns the call during a simultaneous ringing call. The other called terminal ends the call and stops ringing, so that the user does not answer the call. The situation where the called terminal is cut off due to a misconnection in the virtual number service will not only cause the calling user to recall the personal number of the called user, but also spend extra calls, and leak privacy due to the misconnection of other users. . Summary of the invention

In view of this, the object of the present invention is to provide a service triggering method based on the original called number information, which can solve the problem that the called terminal call is cut off due to misconnection in the virtual number service. According to the above purpose, the specific technical solution of the present invention is implemented as follows:

A service triggering method based on original called number information, the method includes:

A. Set the corresponding relationship between different original called number information and operation identification in the called terminal in advance;

B. The called terminal obtains the original called number information carried by the incoming call when it connects to an incoming call;

C. The called terminal determines the corresponding operation identifier from the corresponding relationship described in step A according to the original called number information, and uses the operation identifier to instruct the called terminal to perform the corresponding operation.

The original called number information is the original called number.

A short number corresponding to the original called number is set, and the original called number information is a short number corresponding to the original called number.

The original called number is a personal number in a virtual number service.

The original called number is a terminal number in a call forwarding service.

The operation identifier is set to one or a combination of a voice prompt operation identifier, a light-emitting prompt operation identifier, a calling terminal number prompt operation identifier, a display image operation identifier, and a text operation identifier.

The step A further includes: when the called terminal is a fixed called terminal equipped with more than one subsidiary terminal, setting a correspondence between different original called number information and an operation identifier indicating the operation of the corresponding subsidiary called terminal on the fixed telephone. relationship.

The fixed called terminal is a landline of a cordless telephone; the accessory terminal is a sub-phone associated with the landline.

The step B further includes: the called terminal does not obtain the original called number information when continuing an incoming call, then the called terminal instructs the called terminal to perform a corresponding operation according to a preset default operation identifier, or does not response.

The step B further includes: if there is no one carried in the incoming call in the corresponding relationship The operation identifier corresponding to the original called number information, the called terminal uses a preset default operation identifier to instruct the called terminal to perform a corresponding operation, or does not respond.

A service triggering method based on original called number information. A corresponding relationship between different original called number information and an operation identifier is set in a called terminal in advance. The method includes:

A1. The network-side device obtains the actual called terminal number corresponding to the original called number from the pre-stored correspondence between the original called number and the actual called terminal number according to the original called number;

B1. The network-side device continues to call the called terminal switch according to the actual called terminal number, and sends the original called number and the actual called terminal number of the call to the called terminal switch;

Cl. The called exchange calls the called terminal according to the actual called terminal number, determines the original called number information of the call according to the original called number of the call, and sends the original called number information to the called Terminal

D 1. The called terminal obtains the original called number information carried by the incoming call when the called terminal continues the call;

El. The called terminal determines the corresponding operation identifier from the corresponding relationship described in step A according to the original called number information, and uses the operation identifier to instruct the called terminal to perform the corresponding operation.

The method further includes:

The called terminal performs a corresponding calling operation according to the original called number information.

The original called number information is the original called number.

In step A1, the correspondence between the original called number and the actual called terminal number is stored in the personal number server.

The step B1 further includes: sending the calling number of the current call to the called exchange.

The step C1 further includes: the called end switch assigns the calling number of this call The code is sent to the called terminal.

When the original called number and the actual called terminal number cannot be directly sent by the calling switch to the called switch, the step B1 is:

When the calling exchange sends the calling number to the called exchange when the call is connected, it sends the call-related information including the calling number, the original called number, and the actual called terminal number to the call server. The call server changes the original called number and the actual called terminal number corresponding to the calling number according to the calling number;

The called exchange obtains the original called number and the actual called terminal number of the call from the call server according to the calling number.

The call server sends the original called number of the current call and the actual called terminal number to the called end switch according to the actual called terminal number.

When the actual called terminal number cannot be directly sent from the calling-end switch to the called-end switch, the step B1 is:

When the calling exchange sends the original called number to the called exchange when connecting the call, it also sends the call-related information including the calling number of the current call and the original called number to the call server. The called number changes the calling number corresponding to the original called number;

The called exchange obtains the actual called terminal number of the call from the call server according to the original called number. The method further includes: when the calling end switch sends the original called number information to the called end switch, adding a number prefix to the original called number information, and the called end switch according to the number of the original called number information The first judges that the number is the original called number.

When the original called number cannot be directly sent from the calling-end switch to the called-end switch, the step B1 is:

When the calling exchange sends the actual called terminal number and the calling number to the called exchange when the call is connected, the call including the calling number of the current call, the original called number, and the actual called terminal number will be called. The relevant information is sent to the call server, and the call server changes the original called number corresponding to the actual called terminal number and the calling number according to the calling number and the actual called terminal number;

The called exchange obtains the original called number of the call from the call server according to the actual called terminal number and the calling number.

The calling number is the number of the actual calling terminal, or the calling personal number, or the calling personal number and the number of the actual calling terminal.

The call server is a service control point in the intelligent network, a home location register of the fixed network in the fixed network, and a virtual number server in the virtual number service network.

When the original called number information is a short number, the method further includes: presetting a correspondence relationship between the original called number and different short numbers;

The short-number corresponding to the original called number is determined according to the preset correspondence relationship of the original called number query, and the short number is sent to the called terminal.

When the original called number information is a short number, the method further includes: presetting a correspondence relationship between different original called numbers of the same actual called terminal number and different short numbers.

The method further includes:

Set the corresponding relationship between the short number and the caller identification in advance; The called-end exchange obtains an incoming call alert identifier corresponding to the short number by querying a preset correspondence according to the short number, and instructs the called terminal to perform a corresponding call operation according to the incoming call alert identifier.

The method further includes: presetting the correspondence between different original called numbers of the same actual called terminal number and different incoming call alert identifiers;

The called-end switch queries the preset correspondence on the called-end switch according to the original called number and the actual called-terminal number to obtain the caller identification corresponding to the original called number on the actual called-terminal number, indicating The called terminal performs a corresponding call operation according to the incoming call alert identifier.

The process of performing the corresponding call operation is:

The correspondence between the original called number or the incoming call alert identifier and the incoming call tone is set in advance; the called-end switch determines the incoming call alert tone corresponding to the incoming call alert identifier according to the corresponding relationship, and instructs the called terminal to continue the call with the incoming call alert tone.

The corresponding relationship is set on the call server or the called end switch.

It can be seen from the foregoing solution that the present invention sets different operation identifiers on the called terminal according to different original called number information, and saves these correspondences. When the called exchange connects the call, it obtains the corresponding original called number information, and when it calls the corresponding actual called terminal, it sends the obtained original called number information to the corresponding called terminal. After the called terminal receives an incoming call, it determines whether the call carries the original called number information. If it does not carry it, it performs the corresponding operation according to the default operation identifier. If the called terminal finds that the call carries the original called number, Information, it indicates that this is a call directed to the original called number, and the called terminal finds a corresponding operation identifier to instruct the called terminal to perform a corresponding operation according to the stored correspondence between the original called number information and the operation identifier. Furthermore, the original called number information may be the original called number itself, or a short number corresponding to the original called number. The original called number here is the called number used when the caller initiated the call. The calling number can be a personal number in a virtual number service or an actual terminal number in a call forwarding service.

The original called number information corresponding to different original called numbers can be different. On the same called terminal, different original called number information can be set to correspond to different operation identifiers. Therefore, when users with different original called numbers share the same When a called terminal is used, this method can avoid the truncation problem caused by the original called number to a user being misconnected by other users.

In order to make the objectives, technical solutions, and advantages of the present invention clearer and clearer, the following describes the present invention in further detail with reference to the embodiments and the accompanying drawings.

A specific implementation method of the present invention is shown in FIG. 1. FIG. 1 is a service trigger method based on the original called number information of the present invention. The specific steps are as follows:

Step 100: Set the correspondence between different original called number information and the operation identifier in the called terminal in advance;

Step 101: When the called terminal continues an incoming call, determine whether the incoming call carries If there is original called number information, if yes, go to step 102; otherwise, go to step 105; Step 102: The called terminal obtains the original called number information carried by the incoming call; Step 103, the called terminal according to The corresponding relationship set in step 100 determines whether the original number information carried by the incoming call has a corresponding operation identifier, and if so, proceeds to step 104; otherwise, proceeds to step 105;

Step 104: The called terminal instructs the called terminal to perform a corresponding operation according to an operation identifier corresponding to the original called number information.

Step 105: The called terminal uses a preset default operation identifier to instruct the called terminal to perform a corresponding operation, or does not respond.

The original called number information described in the present invention may be the original called number itself. After the short number corresponding to the original called number is set, the original called number information may also be a short number corresponding to the original called number.

The original called number is the called number used by the caller when initiating the call. When the virtual telephone number service is implemented, the original called number may be a personal number; when the call forwarding service is implemented, the original called number may be the called terminal number of the initial call of the calling party.

The called terminal used by the user may be a shared called terminal, for example, the office called terminal used by the user is shared with a colleague, and the called terminal used by the user at home is shared with the family. Therefore, this embodiment pre-sets the called terminal at the called terminal. For example, the original called number information is a personal number. On the phone, different operation identifiers are set and stored according to different personal numbers. When the called terminal receives an incoming call, the called terminal determines whether the incoming call is A personal number is carried. If so, the corresponding operation identifier is selected according to the personal number carried in the call to instruct the called terminal to perform the corresponding operation. For example, the operation is to prompt the called user through different voice prompts, so that the user judges based on the voice prompts. Whether it is an incoming call to determine whether to answer the incoming call. If the incoming call does not carry a personal number, the terminal directly instructs the terminal to perform a default operation by using a preset default operation identifier. For example, the default operation may be a default tube order. Incoming call alert, such as Zhen Zheng, to remind the called user.

The present invention provides a called terminal with a function of saving and maintaining the original called number information, such as a personal number, and a list of operation ID correspondence relationships, that is, the called terminal is set according to different original called number information, such as a personal number. Different operations are identified and stored. When the communication system uses the original called number, such as a personal number, to make a call, the called terminal receives the incoming call and according to the original called number information carried by the incoming call, such as the personal number from the stored correspondence. Find the corresponding operation ID in the list and perform the corresponding operation.

An example is used to describe how to set the original called number information, such as the personal number, and the corresponding list of operation identifiers on the called terminal.

Assume that user A and user B share an office called terminal with the number 1 and a laboratory called terminal with the number 2 and the personal number of user A is 11 and the personal number of user B is 12. User A and user B all associates the called terminal of the office with his personal number and stores it in the personal number server. The communication system can use the personal number of user A to initiate a call to the called terminal of user A or use the personal number of user B. Initiate a call to the called terminal of user B's office.

When the corresponding operation ID is set at the called terminal according to different personal numbers, as shown in Table 1, the original called number is the personal number, and the original called number information is the original called number itself:

Personal number Operation ID

11 Play music identifying user A

12 Play music identifying user B

Table 1

As can be seen from Table 1, when the personal number is 11 of the user A, the operation identifier can be set to play the music identifying the user A; when the personal number is 12 of the user B, the operation identifier can be set to play the identification user B Music. This table 1 is stored in the called terminal. The operation identifier is set to one or a combination of a voice prompt operation identifier, a light-emitting prompt operation identifier, a calling terminal number prompt operation identifier, a display image operation identifier, and a text operation identifier.

When the operation identifier is set to sound an incoming call, such as: calling the user's name directly, the user's voice information is recorded in advance and the voice information file is saved, and the file is set to correspond to the corresponding voice prompt operation identifier.

The operation identifier can be a voice file name, corresponding to the corresponding voice message; or it can prompt the incoming call for light emission, such as flashing different color indicator lights to remind the incoming call or flashing red

(RedGlitter) The indicator flashes red to indicate an incoming call; or it can be a combination of various operation indicators, such as: prompting an incoming call by displaying an image and prompting an incoming call by displaying text or recording the original called number information and calling information as a log, and the user Check it out.

In practice, it can also be set as follows: When a shared called terminal receives a call from a personal number, the called terminal uniformly prompts an incoming call alert that identifies the personal number to ring, and then the called user with a different personal number displays the call through the caller ID. The user uniquely identifies images or text of different called users to distinguish the called users.

The present invention can also set the operation identifier in combination with the calling terminal. For example: You can set the incoming call alert to "User M calls User A". At this time, by saving the calling trigger list in the called terminal, when the call arrives, the called terminal combines the incoming call according to the calling trigger list and Table 1. Prompt way.

The above mainly uses the original called number information as a personal number for illustration. In practice, the original called number information may also be a short number corresponding to the personal number. That is, the original called number, such as a personal number, is set in advance. When the called exchange connects the call to the called terminal, the original called number information transmitted to the called terminal corresponds to the original called number. In this case, when the called terminal connects to the call, the original called number information obtained from the call information is a short number. The called terminal changes the original called number according to the short number. The corresponding operation identifier is determined in the correspondence between the code information and the operation identifier, and then the called terminal is prompted to perform the corresponding operation according to the operation identifier. As shown in Table 2, when the original called number information is a short number:

Short number Operation ID

01 Play music identifying user A

03 Play music identifying user B

Table 2

When the called exchange transmits the original called number information to the called terminal, it can be performed in a dual-tone multi-frequency (DTMF) mode or a frequency shift keying (FSK) mode. The original called number information can be transmitted to the called terminal as a separate information element, or it can be transmitted to the called terminal together with the calling number. For example, when the original called number information is a short number, the short number may be appended to the calling number and transmitted to the called terminal as part of the calling number. For example, the short number is a two-digit number, which can be placed behind the calling number as part of the calling number, and the short number information is transmitted to the called exchange. The called exchange intercepts the short number from the calling number.

In practice, a flag may be set to distinguish whether the original called number information is a short number, and whether it is transmitted alone or as part of the calling number to the called terminal. The called terminal obtains the calling information from the calling information according to the flag. Corresponding original called number information.

The foregoing operation of setting a short number corresponding to a personal number may be performed on a called exchange, or may be implemented in an intelligent network manner, that is, at a service control point (SCP) of the intelligent network. For example, on the SCP, a short number corresponding to a personal number is set. The calling switch finds the short number corresponding to the personal number from the SCP according to the personal number, and places the short number behind the calling number as Part of the calling number, then the call is connected to the called exchange, and the called exchange connects the call to the called terminal. When the called terminal enables the calling number identification function, the called exchange will The calling number is sent to the called terminal. After receiving the calling number, the called terminal can intercept the short number added previously from the calling number.

In fact, when the personal number service is implemented by an intelligent network, such as the personal number server function through SCP, a personal number server will store the relationship between a personal number and its corresponding actual terminal number. When the calling exchange receives a call, it will use the actual terminal number, and then use the actual terminal number to continue the call.

In order to transmit the personal number information through the short number, that is, the original called number information is transmitted to the called terminal, the correspondence between the personal number and the short number can be set in the personal number server. When the calling switch receives the call initiated by the calling terminal, it obtains the actual called terminal number and short number from the personal number server according to the personal number, and then continues the call according to the actual called terminal number, and then sets the short corresponding to the personal number. The number is sent to the called exchange. When the called exchange connects the called terminal to the called terminal, it sends the short number to the called terminal. Here, it may further include, when setting the short number according to the called personal number, referring to the actual called terminal number bundled with it. That is, for the same actual called terminal number, a short number corresponding to each personal number is set to ensure that the correspondence set for the same actual called terminal number is different from the short numbers of different personal numbers, thereby avoiding the conflict of short number settings. .

The following example is a case where the original called number is a personal number, and the original called number information is the personal number itself, and the original called number information is transmitted to the called exchange: As shown in FIG. 2, the present invention is based on individuals. An end-to-end flowchart of service triggering by numbers, the specific steps are:

Steps 200 to 202. The calling user of the communication system uses the number to call the called user. The calling switch determines whether the number is the user's personal number. If yes, go to step 103. Otherwise, follow the steps in the prior art. Communication process execution;

Step 203: The calling switch searches for the pair of personal numbers from the personal number server. Corresponding called terminal number, and determine the called end switch according to the called terminal number corresponding to the personal number, and the calling end switch pairs the corresponding called end switch to the called end switch according to the called terminal number corresponding to the personal number. Initiate a call carrying the personal number, and the initiated call carries the personal number of the called user. In practice, it may also carry a call flag that identifies whether the personal number is carried;

Step 204: The called-end exchange continues to call the called terminal, and sends the personal number carried by the received call to the called terminal;

Steps 205 to 206: After receiving the call, the called terminal determines whether the call carries a personal number. In practice, the call can be determined based on whether the call carries a personal number flag. If yes, go to step 207; otherwise, Call alert by ordinary ringing;

Step 207: The called terminal finds a corresponding operation identifier according to the stored correspondence between the personal number and the operation identifier, and performs a corresponding operation.

If the operation identifier corresponding to the personal number is not stored in the called terminal, the called terminal uses a preset default operation identifier, such as a normal ringing mode, to alert the incoming call.

If the corresponding relationship between the personal number and the operation identifier is not stored in the called terminal, such as: The mobile called terminal does not store the corresponding relationship between the personal number and the operation identifier, then the default operation identifier is directly used, for example, the normal ringing method The terminal prompts for an incoming call without judging whether the call carries a personal number.

In practice, the user can also set the called terminal to perform corresponding operations on the specified original called number, and for the original called number that is not specified, the called terminal does not perform corresponding operations. For example, users A and B share one called terminal number and use two called terminals T1 and T2 in series. In this case, user A sets the called terminal T1 as: Only when the original called number of the incoming call is user A. When the personal number of 11 is 11, T1 rings to alert the incoming call; User B is set at the called terminal T2 as: Only when the original called number of the incoming call is User B When T2's personal number is 12, T2 rings to alert the incoming call. In this way, when there is an incoming call from user A, the called terminal T1 rings, and the called terminal T2 does nothing; accordingly, when there is an incoming call from user B, the called terminal T2 rings, and the called terminal T1 does nothing.

The personal number server may be a home location register (HLR) device of the communication system, may also be an ONLY server, or may be another specialized personal number server.

Table 1 is used to illustrate the process described in FIG. 1 of the present invention.

When a calling user of the communication system calls user A through personal number 11, the corresponding relationship between the personal number 11 of user A and the actual called terminal number stored by the calling party switch to which the calling user belongs is stored through the personal number server ', The number of the actual called terminal to be called is 1, and a call is initiated to the number 1. The call carries the personal number 11 of user A. The call is connected through the called terminal switch, and is finally received by the called terminal of number 1. When the called terminal determines that the call carries a personal number, the called terminal learns that the corresponding operation identifier is the music identified by the user A according to the stored Table 1, and plays the music, indicating that the user A To answer the call.

When the present invention sequentially calls the called terminal corresponding to the personal number through the personal number, according to the steps described in FIG. 1, all the called terminals of the user are called sequentially. When the present invention makes a Zhenling call to the called terminal corresponding to the personal number through the personal number, according to the steps described in FIG. 1, all the called terminals corresponding to the personal number are placed into the "call" at the same time.

When users with different personal numbers share a called terminal, different operation identifiers are set according to the different personal numbers, and stored in the called terminal, so that different users can use the actual terminal corresponding to the defined operation identifier. The corresponding answering is performed in response, thereby avoiding the user who does not have the personal number from mistakenly listening to the call, and also avoiding the problem of interrupting the entire call process due to a wrong incoming call in the implementation of the virtual number service.

When the communication system performs a call transfer service, the present invention may also implement The corresponding relationship between the original called terminal number and the terminal operation identifier is set in the international called terminal and the corresponding relationship is stored in the actual called terminal after the transfer. That is, the personal number described in Table 1 is replaced with the original called terminal number, and Set the operation ID corresponding to the original called terminal number. When calling with the original called terminal number, the transferred actual called terminal finds the corresponding operation identifier and performs the corresponding operation according to the corresponding relationship, for example, the operation may be an incoming call alert. This process can avoid the situation where the called terminal transferred by the called user's incoming call is shared with other users by mistake, and is misconnected by other users.

When a called terminal is equipped with several cordless handsets for a fixed telephone, the present invention can also set and store the correspondence between personal numbers and cordless handsets on the fixed telephone, so that the fixed telephone can be based on different personal numbers, Connect incoming calls to different cordless handsets. The specific process is as follows: The called terminal obtains the corresponding original called number information when it connects to the call, and determines the corresponding operation identifier and corresponding handset address information according to the corresponding relationship that is set. The operation identifier includes the operation identifier 1 and the operation identifier. 2. Operation ID 1 indicates the fixed phone, and then it is determined whether the corresponding handset is turned on. If it is not turned on, use operation ID 2 to instruct the called fixed phone to alert the incoming call. If the corresponding handset is turned on, the call is directly connected to the corresponding handset. The sub-machine also instructs the corresponding sub-machine to call the incoming call with the corresponding operation identifier 2.

In practice, when the calling terminal calls the called terminal through the personal number, when the call is connected to the calling switch, the calling switch triggers the intelligent network server to respond accordingly according to the personal number, and the intelligent network server The number finds out the corresponding called terminal number and the short number assigned to the personal number. Then, the intelligent network server instructs the calling switch and the called switch to implement connection, and sends the short number to the called switch and the called switch. Then send the short number to the called terminal of this call.

Correspondingly, the corresponding relationship between different short numbers and different incoming call alerts is also set on the called terminal. When the called terminal receives an incoming call, it can use the short number received to find the corresponding incoming call alert that prompts the personal number. Thus, the user having the personal number is indicated To answer the call.

How is the original called number information transmitted to the called exchange? This transmission method can be various. For example, for a case where the original called number is a personal number and the original called number information is a short number, first, a short number corresponding to the personal number is set. At this time, when the original called number information is transmitted to the called exchange, the personal number itself is not transmitted, but the corresponding short number.

As shown in FIG. 3, FIG. 3 is a flowchart of a calling method for transmitting original called number information to a called end office according to the present invention. The specific steps are as follows:

Step 300: The calling user initiates a call by using the original called number;

Step 301: The calling switch obtains the actual called terminal number from the personal number server according to the original called number;

Because the correspondence between the original called number and the corresponding actual called terminal number has been stored in the personal number server in advance, the calling switch is based on the original actual called terminal number;

Step 302: The calling switch performs route selection according to the actual terminal number, and continues the call;

Step 303: The calling switch directly sends related information such as the calling number, the original called number, and the actual called terminal number of the current call to the called switch.

Step 304: The called-end exchange connects the call to the called terminal according to the number of the actually called terminal, determines the original called number information of the called based on the original called number, and sends the original called number information to the called terminal. In this way, the called terminal performs different calling operations according to different original called number information.

The original called number information described in the present invention may be a personal number or a short number. A specific embodiment is used to describe the method provided by the present invention.

When a calling terminal uses a personal number to initiate a call, the calling switch, that is, the originating office switch, determines whether the called number is based on the prefix of the called number, such as "15" in 15512345678. The personal number, if it is, from the personal number server, that is, the service control point (SCP), if a fixed network home location register (FHLR) similar to the home location register (HLR) in the mobile network is added to the fixed network, the individual The number server is FHLR, which searches for the actual called terminal number corresponding to the personal number, and then the calling switch determines the route according to the actual called terminal number corresponding to the personal number, connects the call to the called terminal switch, and The personal number information is sent to the called end exchange, and when the called end exchange connects the call, the personal number information is sent to the called end according to the actual called end number.

When the calling end exchange sends the original called number information to the called end exchange, it can directly extend the ISDN user part (ISUP) signaling of the extended integrated service digital network, for example, by adding the original destination information to the general information of the ISUP signaling Call the personal number field. When the original called number information is a short number, the calling switch can attach the short number to the calling number and send it to the called exchange; the called exchange can attach the short number to the calling number and send it to the called. terminal. For the original called number being a personal number, the correspondence between the short number or short number or summary information corresponding to the original called number can be stored in the personal number server, such as in SCP, as shown in Table 3:

Original called number Short number

15512345678 1

15587654321 2

15512337788 1

15522335678 2 The calling switch obtains the corresponding actual called terminal number from the personal number server according to the called personal number, and obtains the short number corresponding to the personal number. While connecting the call to the called exchange according to the called actual terminal number, After adding the short number to the calling number, the short number is transmitted to the called exchange, and the called exchange obtains the additional short number information from the calling personal number information element, that is, the original called number information.

When the present invention is implemented in an intelligent network, as shown in FIG. 4, FIG. 4 is a flowchart of Embodiment 1 of a calling method for transmitting an original called number to a called end office according to the present invention. The specific process is as follows: Step 400: The calling user initiates a call using the original called number;

Step 401: The calling switch obtains the actual called terminal number from the personal number server according to the original called number;

Step 402: The calling switch transmits call-related information such as the calling number and the original called number of the call to the service control point (SCP). The SCP can find the corresponding record according to the original called number, and use the calling The number changes the record and then returns a confirmation message to the calling switch. The call-related information sent by the calling switch to the SCP may further include the actual called terminal number;

Step 403: After receiving the confirmation message, the calling switch replaces the calling number with the original called number, performs routing based on the actual terminal number, and continues the call, and sends the original called number as the calling number to Called exchange

Step 404: After the call is connected to the called exchange, the called exchange obtains other call-related information such as the calling number used by the call from the SCP according to the original called number.

* ^,

Step 405: The called-end switch initiates a call to the called terminal according to the actual called terminal number, and sends the original called number to the called terminal, so that the called terminal performs different calling operations according to different original called numbers.

When the calling number is replaced with the original called number, it is transmitted to the called party through the calling switch. When changing phones, the method described in the present invention can call a special prefix at the original called number, such as "000", to enable the called exchange to determine that the number is the original called number. For example, before the original called number 15512345678, "000" is added as a mark to distinguish the calling number, and the number digit 00015512345678 stored in the calling field is obtained. The called exchange can determine that the original called number 15512345678 is actually stored in the calling number field according to "000" before the number in the calling number field.

When the method described in FIG. 4 is implemented, calls for the same original called number are allowed only once at the same time, that is, when the SCP receives a request for changing call-related information initiated by a calling switch, and After the original called number of the original callee changed the corresponding record, during this time, another calling switch initiated a request for the original called number and requested the SCP to change the corresponding record. The SCP will reject the other calling switch. Query the original called number and request for change of call-related information to avoid conflicts.

As shown in FIG. 5, FIG. 5 is a flowchart of Embodiment 2 of a calling method for transmitting an original called number to a called end office according to the present invention. The specific process is as follows:

Step 500: The calling user initiates a call by using the original called number;

Step 501: The calling switch obtains the actual called terminal number from the personal number server according to the original called number;

Step 502: The calling switch transmits the call-related information such as the calling number, the original called number, and the actual called terminal number to the service control point (SCP). The SCP may refer to the actual called terminal number and the calling number. The calling number finds the corresponding record, changes the record with the original called number, and then returns a confirmation message to the calling switch.

Step 503: After receiving the confirmation message, the calling switch performs routing based on the actual terminal number, and continues the call;

Step 504: After the call is connected to the called exchange, the called exchange obtains the original called number used by the call from the SCP according to the actual called terminal number and the calling number. Codes and other call-related information;

Step 505: The called end switch initiates a call to the called terminal according to the actual called terminal number, and sends the original called number to the called terminal, so that the called terminal performs different calling operations according to the different called number.

The SCP in the method described in FIG. 5 may also be a number portability server (NP).

When the calling switch is connected to the call, it can send the calling number to the called switch. The called switch obtains the original called number used in the call from the SCP according to the calling number, and will call the original number. Sent to the called terminal of this call. The calling number here can be a personal number. It can also be the calling terminal number.

The present invention can also send the modified record directly to the called end exchange after the SCP has modified the record, and the called end exchange uses the record to match the call that is currently being connected, that is, by using the calling number in the message and the original destination number. The called number and the actual called terminal number match the call currently being connected.

In order to avoid conflicts between short numbers corresponding to multiple different original called numbers based on the same actual called terminal, for example, the short numbers corresponding to two personal numbers are the same, and exactly the same personal numbers are set for the two personal numbers Terminal number. In this way, when the actual called terminal receives the short number, it cannot distinguish which personal number is the information. Therefore, an actual called terminal number field can be further added on the basis of Table 3. For example, in the SCP or the called switch, the original called number corresponding to the same actual called terminal number can be saved. The short number or summary information, that is, the short number or summary information corresponding to the original called number based on the same actual called terminal number is guaranteed to be different, so as to avoid the above-mentioned conflict. As shown in Table 4:

2 ! Actual terminal original called number short number

28123456 15512345678 1

28123456 15587654321 2

28223399 15512337788 1

28223399 15522335678 2

It can be seen from the table that when the actual terminal number is 28123456, the actual terminal number corresponds to the two original called numbers: 15512345678 and 15587654321, and the SCP or the called end switch respectively sets short numbers for the two original called numbers: 15512345678 sets the short number to 1; 15587654321 sets the short number to 2.

When the correspondence described in Table 3 is stored in the called end exchange, the called end exchange can obtain the corresponding short number stored by itself according to the actual called terminal number and the original called number. The original called number information transmitted by the called terminal exchange to the called terminal is a short number, and the called terminal can distinguish the actual called user of the incoming call according to the short number. When the correspondence described in Table 3 is stored in the SCP, the called-end switch obtains the calling number and the short number corresponding to the original called number from the SCP according to the original called number; or the called-end switch According to the actual called terminal number and the calling number, the short number corresponding to the original called number at the terminal is obtained from the SCP, and the obtained short number is sent to the called terminal, and the called terminal can use the short number to Differentiate the actual called user of the incoming call.

In Table 3, it is also possible to add an incoming call alert identifier, and set the correspondence between the incoming call alert identifier and the short number. When the called end switch obtains the short number, obtain the corresponding incoming call alert identifier corresponding to the short number according to the corresponding relationship, and The caller ID and short number are sent to the corresponding called terminal, and the called terminal can choose its own response method according to the caller ID or short number, for example: directly play the caller tone according to the caller ID, or according to the short number Perform the preset sound and light call prompt operation.

In practical applications, the called-end exchange may not transmit the short number to the called terminal, but may convert the short-number into an incoming call alert identifier according to the set correspondence, and set different incoming call identifiers in the called-end exchange in advance. Correspondence to different incoming call prompt sounds, the incoming call prompt sound is determined according to the incoming call prompt identifier, the incoming call prompt tone is transmitted to the called terminal, and the called terminal plays the incoming call prompt tone.

Figures 4 and 5 show an example in an intelligent network. When in a fixed network, if the fixed network has a fixed network HLR, that is, FHLR, the described implementation is the same as that of Figures 4 and 5, except that The SCP in the intelligent network is replaced with the HLR in the fixed network to change each call record.

When the fixed network or intelligent network supports the ring back tone service, different original called numbers can be set on the calling end switch to correspond to different color ring backtones. When the calling party uses the original called number to make a call, the calling end switch If the corresponding correspondence relationship is obtained by the original called number, the corresponding voice prompt CRBT is received, and then the calling switch exchanges the call according to the actual called terminal number inquired from the personal number server, and instructs the called terminal supporting the CRBT service to perform corresponding voice Prompt the ring back tone, so that different ringtones can be distinguished by different voice prompts.

Similarly, according to the above method, for a case where a mobile terminal number is applied as a personal number, that is, a call transfer situation of a mobile terminal, the mobile terminal number as an original called number can be displayed to an actual final called terminal.

In the call processing method for transmitting the original called number to the called end office, the calling number may be a calling terminal number, or a calling personal number, or may include both the calling terminal number and the calling individual. Number

The personal number server according to the present invention may be an SCP in an intelligent network, or an HLR in a fixed network. Of course, it may also be an HLR in a mobile network, or another virtual number server dedicated to virtual numbers.

The present invention realizes the original called party by transmitting the original called number information to the called end office. The method for identifying a number on a fixed terminal can largely personalize the fixed terminal, thereby promoting further expansion and application of the fixed network and fixed terminal services.

The foregoing is only a preferred embodiment of the present invention, and is not intended to limit the present invention. This kind of preset relationship between the original called number information and the operation mode or identification of the incoming call is set. When the called terminal connects to the call, it obtains the original The called number information, and the called terminal determines the operation mode of the incoming call according to the original called number information, and then the corresponding operation method can implement various functions, which are not listed here. All modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
