5101. Receive a call request for calling a user terminal where the second smart card is located.

5102. When it is confirmed that the call channel cannot be established with the called user terminal where the second smart card is located, the first smart card that is associated with the second smart card is found according to the association relationship between the second smart card and the first smart card.

The confirmation cannot be established with the called user terminal where the second smart card is located, and specifically includes: the second smart card has been logged off, the user terminal where the second smart card is located is shut down, or the second smart card is suspended.

Preferably, the first smart card and the second smart card are activated by the called user information, that is, the first smart card and the second smart card are both real-name SIM cards; optionally, the first smart card and/or the second smart card are further It may be activated in an anonymous manner and used by the called user, that is, a SIM card that is not authenticated by the user; optionally, the first smart card and the second smart card may also be used by different users.

S103. Forward the call request to the client where the first smart card is located.

Optionally, the forwarding process is specifically: the server establishes a call channel between itself and the user terminal where the first smart card is located, broadcasts the message to the called terminal, or informs the calling user of the transfer request by using a short message; optionally, the forwarding The request carries the information of the calling user, so that the called user can decide whether to allow the call channel to be established according to the information of the carried calling user; receive the confirmation message of the called user terminal allowing the call, and the server establishes the calling user and The call channel between the called users.

The embodiment provides a relationship between the smart card and the terminal of the first smart card associated with the second smart card when the session channel cannot be established with the second smart card, thereby ensuring that the second smart card is stopped. After that, the called user can be contacted normally.

The first embodiment is a transfer call application based on the association relationship. In the following second embodiment, how to establish the association relationship between the first smart card and the second smart card is further described.

Embodiment 2

An embodiment of the method for establishing an association relationship is provided by the present invention. This embodiment describes a process for establishing an association relationship between a first smart card and a second smart card. The process is as shown in FIG. 2, and includes:

S201. The server confirms that the first smart card has associated information, and searches for the associated information according to the related information. The second smart card that satisfies the associated condition of the first smart card.

The association information is used to find or establish information about the association relationship between the first smart card and the second smart card, and includes: the phone book information recorded by the first smart card and/or the real name letter corresponding to the first smart card is preferred, and the server confirms that the record has Corresponding to the real name information of the first smart card, the associated information is specifically the real name information corresponding to the first smart card record; the associated condition is that the first smart card and the second smart card correspond to the same real name information. The server searches for a second smart card recorded with the same real name information as the real name information of the first smart card; when the user activates the first smart card using the real name information or uses anonymous activation to subsequently update with the real name information, the server is triggered to perform the confirmation process.

Optionally, the server confirms that the phone book information corresponding to the first smart card is recorded, and the association information is specifically the phone book information corresponding to the first smart card; the second smart card of the associated condition is the first smart card. The matching degree of the phone book information corresponding to the second smart card is greater than a threshold. The server searches for a second smart card whose matching degree with the phone book information corresponding to the first smart card is greater than a threshold; the confirmation process triggers the server to complete when the user uploads the phone book information stored by the user to the server.

Optionally, when the server confirms that the first smart card has no associated information, the process of establishing the association relationship ends.

Optionally, the triggering server confirms that the first smart card has the associated information, in addition to the foregoing two types, the user may initiate a search association request by using the user terminal where the first smart card is located, and may first use the real name information to search, and use the real name in the first real smart card. When the information search method fails or when there are multiple smart cards with the same real name information, the phone book information is further utilized, which is specifically:

When the real name information corresponding to the first smart card is recorded, the second smart card recorded with the same real name information is searched; when it is confirmed that the first smart card does not record the real name information, it is confirmed that the first smart card records the phone. The book information is used to find a second smart card whose matching degree with the first smart card corresponds to the phone book information is greater than a threshold.

S202. The server sends a request for establishing an association relationship to the user terminal where the first smart card is located. The request for establishing the association relationship includes the prompting information of the user password of the second smart card that is required to be returned by the user terminal, and the specific manner may be that the server notifies by using a voice broadcast or a short message. S203. Establish an association relationship according to the confirmation returned by the user terminal to establish an association relationship between the first smart card and the second smart card.

Specifically, the confirmation establishment relationship response includes a user password of the second smart card, and the server checks that the user password of the second smart card in the establishment establishment relationship response is the same as the user password of the second smart card stored in the server. Establishing an association relationship between the first smart card and the second smart card.

This embodiment makes full use of some operations of the existing user. For example, when the user activates the first smart card by using the real name information or uses anonymous activation to update the real name information, the user uploads the stored phone book information to the server. And the automatic search of the first smart card association relationship by the server is implemented on the basis of the operation flow, and finally the association relationship between the first smart card and the second smart card is established by the confirmation relationship established by the first smart card. It reduces the inconvenience caused by the user's active operation and the omission of the establishment of the association due to user negligence.

An automatic triggering mechanism has been established by using the first embodiment and the second embodiment. The server searches for and establishes the association relationship between the first smart card and the second smart card, and can establish a corresponding call channel when the calling user calls the second smart card. The call is forwarded to the terminal where the first smart card is located by using the association relationship. However, if a plurality of smart cards are associated with the second smart card, the user is required to select the terminal where the smart card needs to establish a call channel, and the third embodiment is used for implementing the method.

Embodiment 3

When the embodiment is applied to a relationship between a plurality of smart cards and the second smart card, the user needs to independently select a terminal where the first smart card needs to establish a call channel, and The process is shown in Figure 3, including:

S301. The server receives a request message that the calling user terminal queries the second smart card association relationship. S302. The server searches for one or more smart cards that are associated with the second smart card according to the second smart card identifier in the request message, and returns the found one or more smart card information to the calling user terminal.

Preferably, in the embodiment, the request message includes a second smart card identifier and a time parameter of the second smart card being used by the called user, and the step S302 is specifically: the server according to the Searching for a second smart card identifier in the request message with the second smart card a smart card having an associated relationship; and filtering, according to the activation time and the logout time of the second smart card corresponding to each smart card, the first smart card, the activation time and the logout time of the second smart card recorded by the first smart card The constructed time range includes the time parameter, and the filtered smart card information is sent to the calling user terminal.

Optionally, in the request message, the request message includes a second smart card identifier and real name information of the second smart card, and the server searches for one or more smart cards that are associated with the second smart card. And returning the queried one or more smart card information to the calling user terminal, and step S302 is specifically:

The server searches for each smart card that is associated with the second smart card according to the second smart card identifier in the request message; and filters out the real name information of the second smart card according to the real name information of the corresponding smart card. One or more smart cards, and the filtered one or more smart card information is sent to the calling user terminal.

Optionally, the embodiment further includes:

S303. The server receives a confirmation message that the calling user selects the first smart card as the called party.

S304. The server initiates a call request to the user terminal where the first smart card is located.

Step S304: The call request is initiated to the called user terminal where the first smart card is located, where: the server establishes a call channel between itself and the called user terminal, broadcasts the message to the called terminal, or informs the calling user by using a short message. The transfer request; receiving the confirmation message of the called user terminal allowing the call, the server establishes a call channel between the calling user and the called user.

The embodiment provides a method, and the server used in the first embodiment and the second embodiment automatically finds that the smart card associated with the second smart card may not only exist only in the first smart card according to the association relationship; The terminal returns one or more smart cards that satisfy the request message, and the user terminal further determines which smart card to send the call request to.

The third embodiment is that the server automatically detects the second smart card that has an association relationship with the first smart card, and establishes an association relationship between the two by the user terminal of the first smart card to establish an association relationship; the actual application may encounter the server. The automatic detection mechanism provided cannot be implemented, such as: (1) When the calling user uses the new mobile phone and activates the SIM card; (2) When the calling user wants to establish an association relationship with the SIM card that is not his own. In the fourth embodiment, a method for actively establishing an association relationship with a designated second smart card by the first smart card corresponding user terminal is provided. Embodiment 4

The association relationship can be stored.

Embodiment 5

In the method for establishing an association relationship, the smart card is specifically represented by a SIM card, and the user terminal includes a phone book application, and the functions of the user terminal side in the foregoing embodiment are implemented by the phone book application, including: There is currently used SIM card information. When the first use of the address book application or the application detects that the SIM card information is different from the stored SIM card information, the preferred automatic upload of the local phone book information to the server may also be The phone book application presents the prompt information to the user through the user terminal and completes the operation of uploading the local phone book information to the server after receiving the confirmation operation; the phone book application records the modification of the phone book information on the user terminal and calls in the user update server The book information, the update is specifically uploading the modified phone book information; the preferred phone book application also records the phone book information modification ratio, and the value is the phone book information uploaded by the user terminal compared to the previous time. The information content modified by the information accounts for the ratio of the total contents of the phone book information; The phone book information modification ratio is transmitted to the server together when the user terminal uploads the local phone book or updates the phone book in the server, so that the server further uses the modification ratio to find the associated user account more accurately when performing the matching operation.

In this embodiment, the first smart card is specifically represented by the first SIM card, and the second smart card is specifically represented by the second SIM card. In this embodiment, the user terminal inserts the first SIM card, and completes uploading the local phone book of the terminal to the server. The flowchart for establishing the relationship is shown in Figure 5, including:

5501. The user terminal inserts the first SIM card, and starts the phone book application.

The first SIM card information is not recorded in the phone book application or the verified SIM card information does not match the inserted first SIM card, and the phone book application prompts the user to use the temporary login mode or use the registered login mode, and the temporary login is the default. And does not leave a record of the SIM card information in the phone book application of the user terminal; and the registration login will leave a record of the SIM card information in the phone book application, and will be used when logging in the next time using the SIM card Skip the above prompt process, so that it is started by the default registration login method.

5502. The user terminal logs in to the server, and selects the uploading terminal local phone book.

The temporary login and registration login are required to input a user password corresponding to the first SIM card when the login server is further to be completed.

A data packet consisting of the first SIM card identifier, phone book information, and phone book information modification ratio is uploaded.

S503. The server queries the SIM card database according to the first SIM card identifier to obtain the first SIM card information, and temporarily stores the uploaded phone book information and the phone book information modification ratio according to the first SIM card information.

The server obtains the real name information from the first SIM card information, and when the acquisition succeeds, the process proceeds to S504; when the acquisition fails, the process proceeds to S510.

5504. The server searches for information of a real-name SIM card stored by the server, where the stored real-name SIM card includes an activated state or is in a logout state; when querying a second SIM card that has the same real-name information, the server sends the first SIM to the first SIM. The user terminal of the card sends a request for establishing an association relationship, where the request for establishing the association relationship includes a user password of the second SIM card that requires the user terminal to input the association relationship to be established, and proceeds to S505; the second SIM of the same name information is not found in the query. When the card is in, enter S506. S505: The server receives a response from the user terminal to confirm the establishment of the association relationship, where the response carries the user password of the second SIM card.

At this time, according to the state of the second SIM card, there are the following two processing situations:

1) the second SIM card has been logged out, but the phone book information stored corresponding to the second SIM card has not been deleted, the server adds the second SIM card information in the associated field of the stored first SIM card, and merges the stored second SIM The phone book information of the card and the phone book information of the first SIM card; if the second SIM card also includes a third SIM card with an associated relationship, the association relationship is also followed by the second SIM card being associated with the first SIM card In the associated field of the card.

2) The second SIM card is still in an active state, and the server adds the SIM card information of the other party in the respective associated fields of the stored first SIM card and the second SIM card.

Preferably, when two or more SIM cards having an association relationship have the same SIM card information, such as real name information, two or more SIM cards share a set of SIM card information to reduce the occupation of the storage space.

After completing the above steps, proceed to S514.

The first SIM card information and the second SIM card information include information such as a phone number, a SIM card activation time, an ID card, and/or a user name. If the second SIM card has been logged out, the first SIM card is added. The association information about the second SIM card also includes the logout time of the second SIM card.

5506. The server searches for a matching degree between the phone book information corresponding to each SIM card in the SIM card database and the uploaded phone book information. The matching degree mainly uses the telephone number in the phone book information as the main matching object, and preferably, other information such as the user name, gender and/or birthday corresponding to the number in the phone book information is added as one of the matching objects.

5507. When detecting that the degree of matching between the second SIM card and the first SIM card is greater than a threshold, send a request for establishing an association relationship to the user terminal, where the request includes a user that requires the user terminal to input the second SIM card to be associated. The password proceeds to S509; when the matching degree is less than the threshold, the process proceeds to S508.

The threshold value is calculated by the server according to the modification ratio of the phone book information uploaded by the user terminal, and the phone book information modification ratio is recorded by the phone book application, and includes the user terminal in the local phone book after the last upload or update of the server. The modified content is the ratio of the total local phone book information content, so the phone book information modification ratio and the calculated matching degree in the server are based on the same The summation value is l based on the algorithm; the same algorithm is the same as the phone book information involved in the calculation, for example, the name, the mobile phone number or the address in the phone book information is used as the calculation parameter, and the same calculation formula is used. result. According to the above principle, based on the phone book information modification ratio value, and adding a certain fluctuation range to set the threshold value, the preferred deviation range does not exceed 5%.

S508. The server stores the temporarily stored phone book information corresponding to the first SIM card information, and proceeds to S514.

S509. The server receives an acknowledgement from the user terminal that carries the password of the second SIM card user to establish an association relationship.

2) The second SIM card is still active, then the server is storing the first SIM card and the second

The respective associated fields of the SIM card add the SIM card information of the other party.

Preferably, when two or more SIM cards having an association relationship have the same SIM card information, such as real name information; then two or more SIM cards share a set of SIM card information to reduce the occupation of the storage space.

After completing the above steps, go to S514.

The first SIM information card includes information such as a phone number, a SIM card activation time, an ID card, a user name, and the like, and the second SIM information card only includes a phone number and a SIM card activation time; if the second SIM card has been logged out, The associated information about the second SIM card added in the first SIM card further includes the logout time of the second SIM card.

S510. The server further searches for a matching degree between the phone book information corresponding to each SIM card in the SIM card database and the uploaded phone book information.

S511, when the matching degree is greater than the threshold, sending a relationship establishment request to the user terminal, the establishing association relationship request includes request information for requiring the user terminal to input the user password of the second SIM card to be associated, and proceeds to S512; When the degree of matching is less than the threshold, the process proceeds to S513. S512. The server receives the confirmation information from the user terminal that carries the password of the second SIM card user. The confirmation information preferably includes the user password information of the second SIM card. Further, the server stores the first SIM card. The associated field corresponding to the second SIM card increases the SIM card information of the other party, and proceeds to S514.

S513. The server temporarily stores the first SIM card information and the corresponding phonebook object to generate a phonebook backup without associated information for the first SIM card, and deletes the temporarily stored data, and proceeds to S514.

S514. The server returns the association success to the user terminal or creates a phone book backup success.

In this embodiment, when the first SIM card is associated with the second SIM card in this embodiment, in order to reduce the computational complexity, the activation time and the logout time content in the associated information may be accurate only to the year and month; The preferred server may set a retention period and delete the phone book information corresponding to the second SIM card stored on the server after the association is completed or the retention period is exceeded.

If the second SIM card is logged out after being associated with the first SIM, the server prompts the user whether to select the phone book information corresponding to the first SIM card in the merge server and the phone book information corresponding to the second SIM card; Performing, according to the confirmation merge response of the user terminal, performing the operation of combining the phone book information corresponding to the first SIM card and the phone book information corresponding to the second SIM card, and updating the associated second SIM card information in the first SIM card, including the first The logout time of the two SIM cards.

Preferably, after the foregoing merge process is completed, the server sends a synchronization update request to the user terminal, and completes the merged phone book information in the synchronous update server by using the phone book application on the user terminal.

In this embodiment, the preferred phone book information for the SIM card on the server further includes the last update time, and the last update time may be only the modification for the phone number.

In this embodiment, based on the phone book application, by adding the association search between the accounts and the association establishment function, the SIM card used by the same user can intelligently complete the association, and the association precision is increased by increasing the record change ratio.

Embodiment 6

In this embodiment, when the calling user contacts the second SIM card identifier in the local phone book information of the terminal; when the phone book object has been logged out, the subsequent operations are as shown in FIG. 6, including:

S601. When the server detects that the second SIM card of the calling user's call has been logged out, the prompting tone is returned to the calling user: "The second SIM card of the called user has been logged out, and the server is searched for the number. Associated users."

S602. The server retrieves, in the SIM card database, other SIM cards that are associated with the second SIM card.

Since the server in this example has confirmed in S601 that the second SIM card has been logged out, the second SIM card must be stored in the associated field of the associated user to be searched, so the server directly retrieves from the associated fields of each SIM card. The second SIM card confirms whether it is an associated user to be searched for.

S603. After the server finds another SIM card that is associated with the second SIM card, the process proceeds to step S604.

According to the number of other SIM cards, the following methods are available:

When there is only one other SIM card, that is, the first SIM card, the process directly proceeds to step S604. When the plurality of other SIM cards that are found have multiple, first obtain the phone book information stored on the server by the corresponding calling user, and extract the last update time recorded with the second SIM card identifier from the phone book information; Obtaining an activation time and a logout time of the second SIM card in the plurality of SIM card association information of the association found; and finally determining that the time interval formed by the activation time and the logout time includes the update time, that is, Is the first SIM card to be searched for.

If the server does not find another SIM card having an association with the second SIM card, then step S606 is reached.

S604: The server sends a call prompt that carries the information of the calling user to the called user terminal where the first SIM card is found; and sends a call prompt according to the mode set by the called user, which may be a voice broadcast prompt or a short message message. Or other means of notification.

S605. After receiving the contact mode that the called user returns to the calling user terminal according to the prompt, the server sends the associated contact mode of the called user to the calling user, and proceeds to S607.

Optionally, the called user may also return an acknowledgement message for establishing a call channel with the calling user terminal, and the server completes the call connection of the two, and proceeds to S607.

S606, return no confirmation information found.

There may be multiple reasons for the not being found, such as:

1) The called user has not yet established a first SIM card (ie, a newly activated SIM card) and the second The association of the SIM card (the cancelled SIM card).

2) When the first SIM card is installed, the called user rejects the request sent by the server in the second embodiment to establish an association relationship with the second SIM card.

3) The called user terminal has only one usage history of the first SIM card in the server.

S607. End the self-search process of the current server.

In this embodiment, the number of the called user recorded by the calling user is usually after the activation of the number and before the number is cancelled, so that the determination is made with the second SIM card. The associated SIM card can reduce the selection operation of the calling user when searching for multiple associated SIM cards, and improve the intelligence of the server.

However, another situation may be encountered: the second SIM card has been logged off by the called user and resold by the operator to the third user and reactivated by the third user; When the second SIM card is identified, because the second SIM card is in an active state, the server directly establishes a call channel of the calling user terminal and the third user terminal; then the dialing telephone number can be dialed, but the answering person does not want to The called user of the call. Therefore, there is a need for a method for the calling user to be aware that the second SIM card has been reassigned to the third user, and further to find the called user to be called with the second SIM card identifier, so the following embodiment Seven provides a way for the calling user to initiate an association search by providing associated information.

Example 7

The embodiment provides a method for the calling user to find the first SIM card currently used by the called user through the association relationship of the second SIM card in the server. The flowchart is as shown in FIG. 7 , specifically :

S701. Enter a keyword to be searched, and send the keyword to the server. The keyword is preferably server-defined content, such as: a username to which the second SIM card belongs and/or a point in time at which the second SIM card is to be used by the home user.

S702. The server uses the keyword to perform a search.

When the preferred keyword includes the user name and the time point, the server first searches for a second SIM card that satisfies the real name information and the same user name from the SIM card library according to the real name information of each SIM card; The result of the user name search is that when the real name information of the plurality of SIM cards is the same as the user name, the server further searches for the second SIM card belonging to different users according to the above-mentioned search. The activation time and the logout time are determined, and the time interval formed by the said activation time and the logout time is included in the time point, that is, the second SIM card belonging to the called user to be searched; or the real name information is not found. When the SIM card with the same user name (the reason may be that the called user does not use the real name information when using the second SIM card), the server further acquires all activation time and logout time of the second SIM card stored by the server, and determines the The time interval formed by the activation time and the logout time includes the time point, that is, the second SIM card attributed to the called user to be searched.

The server obtains the first SIM card used by the current called user according to the found association relationship of the second SIM card belonging to the called user.

5703. The server selects and returns a search result according to the called user setting.

When the called user is configured to allow any user to use the second SIM card to obtain the first SIM card associated with the second SIM card, the server returns the first SIM card information used by the currently called user acquired in step S703. Give the calling user terminal.

When the called user sets the other SIM card to be authenticated to obtain the first SIM card associated with the second SIM card, the server sends an authentication request message to the called user terminal where the first SIM card is located, and is called After the user terminal returns the response of the authentication, the server returns the first SIM card information to the calling terminal. The authentication request message includes a calling party number, and optionally includes information such as a calling user name and a number location.

5704. Complete the search process.

In this embodiment, after the calling user realizes that the second SIM card has been reassigned to the third user, the calling user can further find the called user to be called by using the second SIM card identifier.

Example eight

An embodiment of the method for establishing and searching for an association relationship is provided by the present invention. In this embodiment, the first smart card is embodied as a first SIM card, and the second smart card is embodied as the second SIM card. After the called user cancels his second SIM card, the first SIM card is activated, and the association relationship between the second SIM card and the first SIM card is established through the server; the association relationship corresponding to one user may include multiple levels, that is, A plurality of phone numbers that a user has used have been associated with each other.

In this embodiment, the calling user can complete the data operation by using an interactive voice response (IVR) or a manual response mode by dialing a service platform number, such as 10086, 10000, or 114. The specific operation of the user to establish the association relationship may be, but is not limited to, the following process: 5801. The user dials the IVR phone 1008653, and the user hears the voice prompt of the IVR broadcast. "Please press 1 for the query operation and 2 for the personal association operation."

5802. After the user inputs 2 through the user terminal, the IVR broadcasts the voice prompt. "Please press 1 to establish the association relationship, press 2 to cancel the association relationship, and press 3" to query the association relationship.

S803. After the user inputs 1, the IVR broadcasts the voice prompt "Please enter the number to be associated, and end with the # key."

5804. After the user inputs the second SIM card to be associated, the IVR broadcasts a voice prompt "Please enter the associated number corresponding to the user password, and end with the # key."

5805. The user inputs a user password corresponding to the second SIM card.

The server verifies that the user password corresponding to the second SIM card input by the user terminal is the same as the password corresponding to the second SIM card stored by the server itself, and further announces the voice prompt "Your association relationship has been established" through the IVR.

The server may be an MSC. After receiving the second SIM card input by the user to establish an association relationship, and verifying that the corresponding user password is passed, the server adds the foregoing in the association mapping table in the associated storage area. The first SIM card information and the second SIM card information, the storage number of the associated number may be a pinyin initial letter of the user name plus a phone number format such as "gxl5072474807", and when actually stored, according to the phone keyboard letter and key correspondence storage As described above, "gxl5072474807, added to the mapping table specifically "4915072474807", where g corresponds to the numeric key 4, X corresponds to the numeric key 9; an optional scheme, will be associated with the user associated with the associated number:

Table 1

In the specific process, the server detects that the user input data is retained if it is the same as the stored one; wherein the usage time period is preferably composed by the server according to the activation time and the logout time of the SIM card, in order to Saving the storage space on the basis of the function, the usage time period value may be composed of two digits and a month after the year; when the server cannot identify the second SIM card input in step S804, the SIM card identifier is used to go to the server to which it belongs. Obtaining the corresponding SIM card information, for example, when the first SIM card belongs to the mobile operator, and the input associated number (the second SIM card identifier) belongs to the Unicom carrier, the mobile server obtains the corresponding corresponding to the Unicom server to which the associated number belongs. Two SIM card association information. The inter-server communication can be implemented by extending the existing signaling interaction. The SMC of the mobile operator and the SMC of the Unicom carrier can be used to implement the interaction process.

When neither the first SIM card information nor the second SIM card information has name information, the server suggests to the user to complete the supplementation of the related attribute field information through the IVR.

In the solution, the relationship of the anti-interference function is increased. In step S805, the IVR broadcasts the voice prompt "Your association relationship has been established, and the other party can obtain your new number by querying your old mobile phone number, and further set the anti-interference. Please press 1, otherwise please hang up."

S 806, after the user inputs the No. 1 key, the IVR broadcasts the voice prompt "Please only allow the calling user to send a short message prompt, please press 1, and only allow the calling user to transfer the contact, please press 2, and at the same time allow the above two methods, please press 3" .

S807. After the user enters the 1st key, the IVR broadcasts the voice prompt. "Setting the completion of the caller will only be able to push the contact request to you via SMS. To return to the upper layer, please press the * key, and end the call."

After the step S807 is completed, the server sends the short message notification field in the associated information of the first SIM card to be true, and the subsequent server confirms that the user terminal of the first SIM card is notified by the short message mode according to the short message notification field. The associated number attempts to contact the local machine (the user terminal where the first SIM card is located).

It is assumed that the called user has completed the establishment of the association relationship between the first SIM card information and the second SIM card information by using the above process, and the calling user queries the currently used user of the called user by using the second SIM card information through the IVR search server. The first SIM card information flow is specifically:

S901, the calling user dials the IVR phone 1008653, and hears the voice prompt of the IVR broadcast. "Please press 1 for the query operation and 2 for the personal related operation."

5902. After the calling user inputs 1, the IVR broadcasts the voice prompt "Please enter the number to be queried, and press the # key to end".

5903. After the calling user inputs the associated number to be searched, the IVR broadcasts a voice prompt "find to There are three associated users who satisfy the associated number. Please enter the name information in the numeric key format of the first letter of the name and end with the # key.

After receiving the second SIM card identifier input by the user, the server searches for the association number of the second SIM card from the associated number mapping table. If the associated number of the associated SIM card is found, the server may find each The attribute field owned by the associated number sends a voice prompt, and the server preferably uses the attribute field commonly owned by the searched associated number as the prompt content, and the commonly owned attribute field in S903 is "name".

If it is not found, it will return to the voice prompt "The associated number you entered is not found. Press the * key to return to the upper layer, and hang up when you end."

S904. After the user inputs the required name information, after the server verification is completed, and the called user terminal establishes the association relationship, the association relationship anti-interference function of the S806-S807 is not set, the server promptly finds that the association is satisfied by the IVR broadcast voice prompt. There is one associated user of the number. To send a transfer request by SMS, press the 1st key. To obtain the voice broadcast, press the 2nd key.

When the "name" attribute field in S904 fails to successfully filter out the first SIM card information to be searched, it preferably uses the "use time period" attribute field, and the specific prompt content is "found to find that the associated number is associated. There are three users. Please enter the time parameter of any time during which the associated number is used in the two-digit plus month format at the end of the year"; since the usage time allocated to each user by each SIM card is mutually exclusive, ie A time period is only possible for one user to use, so that the second SIM card information associated with the first SIM card to be found can be uniquely determined according to the time parameter input by the user.

S905. The calling user input 1 selects to contact by SMS, and the server sends an invitation message carrying the calling user information to the user associated with the associated number.

The invitation message preferably carries the telephone number of the calling user and the name information. If the SIM card used by the user does not pass the real-name authentication, the server sends an invitation message carrying the phone number, and the content may be "user party Tianyi, phone number. 15074557846, I hope to get your contact information,.

When the calling user inputs 2, the server is required to initiate a call to the called user terminal where the first SIM card is located, and the called user obtains the voice prompt of the IVR after receiving the call. "Press the button No. 1, and no longer receive the number. Press the 2nd button ", after the called user selects 1, the server completes the calling user's end. The transfer between the terminal and the called user terminal; after the called user selects 2, the server does not help the calling user to implement the transfer service.

In this embodiment, when the called user is set with S807, and the mode of "setting the completion caller can only push the contact request through the short message" is selected, the S904 is specifically expressed as:

After the user completes the required name information, after the server verification is completed, the voice prompt is further transmitted through the IVR. "There is one associated user who finds the associated number, and the contact invitation is sent by SMS."

The calling user inputs 1 to select to contact by SMS, and the server sends an invitation message carrying the calling user information to the user associated with the associated number and carries a prompt “Please press the No. 1 button for the message that no longer receives the number” After the called user selects 1, the server no longer receives the short message request of the calling user corresponding to the user of the first SIM card.

In this embodiment, based on the method in which the user terminal actively applies for establishing an association relationship, and the calling user actively searches for the first SIM card information currently used by the called user by using the second SIM card information of the called user, a cross-server is provided. The method of lookup makes the scope of the search no longer limited to a single carrier server.
