Description

[Technical Field]

[0001] This invention relates to the field of communication technology, and in particular to a method and system for restoring communication lost. [Background Technology]

[0002] With the increasingly competitive development of telecommunications companies, changing phone numbers due to various reasons such as tariffs and services has become a relatively normal phenomenon. However, phone numbers are reserved for other services provided in daily life (such as financial and corporate services), and changing the number can lead to a state of being out of contact in certain situations. Although telecommunications companies provide certain services to restore contact, these are only paid services for enterprise-level companies, and it is often difficult to restore contact between individuals. [Summary of the Invention]

[0003] In view of this, embodiments of the present invention provide a method and system for repairing lost connections, in order to improve the accuracy and security of lost connection repair.

[0004] On one hand, embodiments of the present invention provide a method for repairing lost connectivity, including:

[0005] In response to the received disconnection repair instruction, the call system sends a disconnection repair service request to the disconnection repair system.

[0006] In response to the loss of connection repair service request, the loss of connection repair system sends a confirmation message to the second called party terminal.

[0007] The second called party terminal responds to the confirmation information and receives the confirmation repair command input by the user;

[0008] The second called party's terminal sends the confirmation repair command to the loss of contact repair system;

[0009] In response to the confirmation repair command, the lost contact repair system sends the phone number corresponding to the second called party terminal to the calling party terminal.

[0010] Optionally, before the calling system sends a connection repair service request to the connection repair system in response to the received connection repair instruction, it includes:

[0011] In response to the user's input of a disconnection repair command, the calling terminal sends the disconnection repair command to the calling system and stops calling the first called terminal.

[0012] Optionally, in response to a user-inputted disconnection repair command, the calling terminal sends the disconnection repair command to the calling system and stops calling the first called terminal, prior to which the following steps are included:

[0013] The calling terminal calls the first called terminal through the calling system based on the telephone number corresponding to the first called terminal.

[0014] The call system sends a query request to the disconnection repair system;

[0015] The disconnection repair system responds to the query request by querying whether there is a potential disconnection between the calling terminal and the first called terminal.

[0016] If the loss of connection repair system detects a potential loss of connection between the calling terminal and the first called terminal, it sends a loss of connection change information to the voice prompt system.

[0017] In response to the lost contact change information, the voice prompt system sends selection information to the calling terminal, which includes a lost contact repair instruction or a continue calling instruction.

[0018] Optionally, in response to the loss of contact information, after sending selection information to the calling terminal, the voice prompt system includes:

[0019] The calling terminal responds to the user's input to continue the call and continues calling the first called terminal.

[0020] Optionally, it also includes:

[0021] If the lost connection repair system finds that there is no potential loss of connection between the calling terminal and the first called terminal, it will continue to call the first called terminal.

[0022] Optionally, it also includes:

[0023] The second called party terminal responds to the confirmation information and receives the user's input instruction to refuse repair;

[0024] The second called party's terminal sends the rejection repair command to the disconnection repair system;

[0025] In response to the rejection repair command, the loss of contact repair system sends a rejection message to the calling terminal.

[0026] Optionally, the disconnection repair system responds to the query request by querying whether there is a potential disconnection between the calling terminal and the first called terminal, including:

[0027] The lost contact recovery system establishes a user telephone number map based on the acquired personal identification information;

[0028] The lost contact repair system establishes a phone number lifecycle map based on the user phone number map and the acquired phone number lifecycle information;

[0029] The lost contact repair system establishes relationships between users based on the dialing times of phone numbers in the phone number lifecycle graph;

[0030] The disconnection repair system determines a potential disconnection relationship map between users based on the association relationships between them;

[0031] If the disconnection repair system finds that the potential disconnection relationship graph between users stores the association between the calling terminal and the first called terminal, then there is a potential disconnection between the calling terminal and the first called terminal.

[0032] On the other hand, embodiments of the present invention provide a lost-connection repair system, including: a call system, a lost-connection repair system, a second called party terminal, and a calling party terminal;

[0033] The calling system is used to send a disconnection repair service request to the disconnection repair system in response to the received disconnection repair instruction;

[0034] The lost connection repair system is used to send confirmation information to the second called party terminal in response to the lost connection repair service request;

[0035] The second called party terminal is used to respond to the confirmation information, receive the confirmation repair command input by the user, and send the confirmation repair command to the lost contact repair system;

[0040] The calling terminal is used to call the first called terminal through the calling system based on the telephone number corresponding to the first called terminal.

[0041] The call system is used to send query requests to the disconnection repair system;

[0042] The lost connection repair system is used to respond to the query request and query whether there is a potential loss of connection between the calling terminal and the first called terminal; if a potential loss of connection is found between the calling terminal and the first called terminal, a loss of connection change information is sent to the voice prompt system.

[0043] The voice prompt system is used to send selection information to the calling terminal in response to the lost contact change information. The selection information includes a lost contact repair instruction or a continue calling instruction.

[0044] In the technical solution of the lost-connection repair method provided in this embodiment of the invention, the calling system, in response to the received lost-connection repair instruction, sends a lost-connection repair service request to the lost-connection repair system; the lost-connection repair system, in response to the lost-connection repair service request, sends confirmation information to the second called party terminal; the second called party terminal, in response to the confirmation information, receives a confirmation repair instruction input by the user; the second called party terminal sends a confirmation repair instruction to the lost-connection repair system; and the lost-connection repair system, in response to the confirmation repair instruction, sends the phone number corresponding to the second called party terminal to the calling party terminal.

Detailed Implementation Methods

[0054] To better understand the technical solution of the present invention, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0055] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0056] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” as used in the embodiments of this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0057] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0058] In related technologies, the method of querying related information based on user identity information involves first retrieving the user's identity document (ID) from the lost number, and then querying the customer's latest number based on the user ID. However, this method is a relatively simple query service and is not suitable for personal business scenarios. Furthermore, it carries the risk of unauthorized access to customer information, resulting in low security.

[0059] Another related technology involves interactive analysis based on call records. By analyzing calls made by missing numbers within a specific time period, associated numbers can be discovered. Interactive profile analysis of calls made by first-level or multi-level associated numbers can identify associated numbers of multiple potential missing numbers. However, user profiles have certain limitations after the time period is limited, and the accuracy cannot be guaranteed by matching interactive profiles made by first-level or multi-level associated numbers.

[0060] To address the technical problems in related technologies, embodiments of the present invention provide a disconnection repair system. Figure 1 This is a schematic diagram of the lost-connection repair system provided in an embodiment of the present invention, as shown below. Figure 1As shown, the system includes: a call system 1, a lost contact repair system 2, a second called party terminal 3, and a calling party terminal 4. The call system 1 is connected to the lost contact repair system 2, the lost contact repair system 2 is connected to the second called party terminal 3, and the lost contact repair system 2 is connected to the calling party terminal 4.

[0061] Calling system 1 is used to send a disconnection repair service request to disconnection repair system 2 in response to the received disconnection repair instruction.

[0062] The disconnection repair system 2 is used to send confirmation information to the second called party terminal 3 in response to the disconnection repair service request.

[0063] The second called party terminal 3 is used to respond to the confirmation information, receive the confirmation repair command input by the user, and send the confirmation repair command to the disconnection repair system 2.

[0064] The lost contact repair system 2 is used to send the phone number corresponding to the second called party terminal 3 to the calling party terminal 4 in response to the confirmation repair command.

[0065] In this embodiment of the invention, the system further includes: a first called party terminal 5, which is connected to the calling party terminal 4, and the calling system 1 is connected to the calling party terminal 4.

[0066] The calling terminal 4 is used to respond to the user's input of a disconnection repair instruction, send the disconnection repair instruction to the calling system 1, and stop calling the first called terminal 5.

[0067] In this embodiment of the invention, the system further includes a voice prompt system 6. The disconnection repair system 2 is connected to the voice prompt system 6, and the voice prompt system 6 is connected to the calling terminal 4.

[0068] The calling terminal 4 is used to call the first called terminal 5 through the calling system 1 based on the telephone number corresponding to the first called terminal 5.

[0069] Call system 1 is used to send query requests to disconnection repair system 2.

[0070] The disconnection repair system 2 is used to respond to query requests and query whether there is a potential disconnection between the calling terminal 4 and the first called terminal 5; if a potential disconnection is found between the calling terminal 4 and the first called terminal 5, a disconnection change information is sent to the voice prompt system 6.

[0071] The voice prompt system 6 is used to respond to the loss of contact change information and send selection information to the calling terminal 4. The selection information includes a loss of contact repair instruction or a continue calling instruction.

[0072] In this embodiment of the invention, the calling terminal 4 is used to continue calling the first called terminal 5 in response to a user's input command to continue the call.

[0073] In this embodiment of the invention, the disconnection repair system 2 is used to continue calling the first called terminal 5 if it is found that there is no potential disconnection between the calling terminal 4 and the first called terminal 5.

[0074] In this embodiment of the invention, the second called party terminal 3 is used to respond to the confirmation information, receive the user's input of a refusal repair instruction, and send the refusal repair instruction to the disconnection repair system 2.

[0075] The disconnection repair system 2 is used to send a rejection message to the calling terminal 4 in response to the rejection repair command.

[0076] In this embodiment of the invention, the lost contact repair system 2 is specifically used to: establish a user phone number map based on the acquired personal identity information; establish a phone number lifecycle map based on the user phone number map and the acquired phone number lifecycle information; establish a relationship between users based on the dialing time of the phone numbers in the phone number lifecycle map; determine a potential lost contact relationship map between users based on the relationship between users; if the potential lost contact relationship map between users stores a relationship between the calling terminal and the first called terminal, then there is a potential lost contact between the calling terminal and the first called terminal.

[0077] In the technical solution provided by this invention, the calling system, in response to the received loss-of-connection repair instruction, sends a loss-of-connection repair service request to the loss-of-connection repair system; the loss-of-connection repair system, in response to the loss-of-connection repair service request, sends confirmation information to the second called party terminal; the second called party terminal, in response to the confirmation information, receives a confirmation repair instruction input by the user; the second called party terminal sends a confirmation repair instruction to the loss-of-connection repair system; and the loss-of-connection repair system, in response to the confirmation repair instruction, sends the phone number corresponding to the second called party terminal to the calling party terminal. The technical solution provided by this invention can provide real-time loss-of-connection repair guidance when a user dials a phone number, and can directly confirm the loss-of-connection status and repairability based on the called party's feedback, thus improving the accuracy and security of loss-of-connection repair.

[0078] Based on the aforementioned disconnection repair system, this invention provides a disconnection repair method. Figure 2 A flowchart of a disconnection repair method provided in an embodiment of the present invention is shown below. Figure 2 As shown, the method includes:

[0079] Step 102: In response to the received disconnection repair instruction, the calling system sends a disconnection repair service request to the disconnection repair system.

[0080] Step 104: In response to the loss of connection repair service request, the loss of connection repair system sends confirmation information to the second called party terminal.

[0081] In this step, the disconnection repair system responds to the disconnection repair service request by sending a confirmation message to the second called terminal, which includes the de-identified information corresponding to the calling terminal.

[0082] Step 106: The second called party terminal responds to the confirmation information and receives the confirmation and repair command input by the user.

[0083] In this step, the second called party's terminal provides feedback to confirm whether to perform a connection loss repair. If a connection loss repair is performed, the user enters a confirmation repair command through the second called party's terminal.

[0084] Step 108: The second called party terminal sends a confirmation repair command to the disconnection repair system.

[0085] Step 110: In response to the confirmation repair command, the lost contact repair system sends the phone number corresponding to the second called party terminal to the calling party terminal.

[0086] As an optional solution, in response to the confirmation of the repair command, the lost contact repair system sends the de-identified information and phone number of the second called party terminal to the calling party terminal.

[0087] In the technical solution provided by this invention, the calling system, in response to the received loss-of-connection repair instruction, sends a loss-of-connection repair service request to the loss-of-connection repair system; the loss-of-connection repair system, in response to the loss-of-connection repair service request, sends confirmation information to the second called party terminal; the second called party terminal, in response to the confirmation information, receives a confirmation repair instruction input by the user; the second called party terminal sends a confirmation repair instruction to the loss-of-connection repair system; and the loss-of-connection repair system, in response to the confirmation repair instruction, sends the phone number corresponding to the second called party terminal to the calling party terminal. The technical solution provided by this invention can provide real-time loss-of-connection repair guidance when a user dials a phone number, and can directly confirm the loss-of-connection status and repairability based on the called party's feedback, thus improving the accuracy and security of loss-of-connection repair.

[0088] This invention provides another method for repairing lost connectivity. Figure 3 and Figure 4 A flowchart of another disconnection repair method provided in an embodiment of the present invention is shown below. Figure 3 and Figure 4 As shown, the method includes:

[0089] Step 202: The calling terminal calls the first called terminal through the calling system based on the telephone number corresponding to the first called terminal.

[0090] Step 204: The calling system sends a query request to the disconnection repair system.

[0091] Step 206: The disconnection repair system responds to the query request and queries whether there is a potential disconnection between the calling terminal and the first called terminal.

[0092] In this embodiment of the invention, Figure 5 for Figure 3 The flowchart of the system responding to the query request and checking whether there is a potential loss of connection between the calling terminal and the first called terminal is as follows: Figure 5 As shown, step 206 specifically includes:

[0093] Step 2062: The lost contact repair system establishes a user telephone number map based on the obtained personal identification information.

[0094] Figure 6 This is a schematic diagram of a telephone number map provided in an embodiment of the present invention, such as... Figure 6 As shown, the telephone number map includes users A, B, and C, and numbers 1, 2, 3, 4, and 5. User A is connected to number 1, user A is connected to number 2, user B is connected to number 2, user B is connected to number 3, user B is connected to number 4, and user C is connected to number 5. Since both user A and user B are connected to number 2, it indicates that number 2 has been recycled and reused. Numbers 1, 3, 4, and 5 have not been reused.

[0095] Step 2064: The lost contact repair system establishes a phone number lifecycle map based on the user's phone number map and the obtained phone number lifecycle information.

[0096] Figure 7 This is a schematic diagram of a telephone number lifecycle map provided in an embodiment of the present invention, such as... Figure 7 As shown, the telephone number lifecycle map includes the telephone number map and telephone number lifecycle information. For example, the first telephone number lifecycle information for number 1 is s: 20130614122308, e: 20200823170523; the second telephone number lifecycle information for number 1 is s: 20210125091256, e: / . s represents the time when the telephone number establishes a relationship with the user, typically through account opening, transfer, or other transactions. e represents the time when the relationship ends between the number and the user. se represents a segment of the telephone number's lifecycle associated with a specific user.

[0097] Step 2066: The lost contact repair system establishes relationships between users based on the dialing time of phone numbers in the phone number lifecycle graph.

[0098] As an alternative, relationships between users can be established based on the time of their first phone call.

[0099] Step 2068: The disconnection repair system determines the potential disconnection relationship map between users based on the association between users.

[0100] Figure 8 This is a schematic diagram of the potential relationship map between users provided in an embodiment of the present invention, such as... Figure 8 As shown, the potential relationship map between users includes a phone number lifecycle map and the relationship between users. The relationship between user A and user B is s: number 1, d: number 3, f: 20170803065402, indicating that the phone number corresponding to the calling terminal is number 1, the phone number corresponding to the called terminal is number 3, and the time of the first dialing of the phone number is 20170803065402.

[0101] Step 2070: If the system finds that the potential disconnection relationship graph between users stores the association between the calling terminal and the first called terminal, then there is a potential disconnection between the calling terminal and the first called terminal.

[0102] As an alternative, the characteristics of potential disconnection are: (1) there is a relationship between the user corresponding to the calling terminal and the user corresponding to the called terminal; (2) the relationship between the telephone number (s) corresponding to the calling terminal and the user corresponding to the calling terminal continues (i.e. the calling number is associated with the calling user during its current life cycle); (3) the relationship between the telephone number (d) corresponding to the called terminal and the user corresponding to the called terminal is broken (i.e. the called number has ended its current life cycle, is frozen, or is not associated with the called user).

[0103] In this embodiment of the invention, after step 206, the system further includes: if the system finds that there is no potential loss of connection between the calling terminal and the first called terminal, it continues to call the first called terminal.

[0104] Step 208: If the disconnection repair system detects a potential disconnection between the calling terminal and the first called terminal, it sends a disconnection change information to the voice prompt system.

[0105] In this step, if the disconnection repair system detects a potential disconnection between the calling terminal and the first called terminal, it indicates that the relationship between the calling terminal and the first called terminal may have changed. The system needs to send disconnection change information to the voice prompt system so that the voice prompt system can notify the calling terminal of the disconnection change information of the first called terminal.

[0106] Step 210: In response to the loss of contact change information, the voice prompt system sends selection information to the calling terminal, which includes a loss of contact repair instruction or a continue calling instruction.

[0107] In this embodiment of the invention, after step 210, the method further includes: the calling terminal responding to the user's input of a continue call instruction to continue calling the first called terminal.

[0108] Step 212: The calling terminal responds to the user's input disconnection repair command, sends a disconnection repair command to the calling system, and stops calling the first called terminal.

[0109] Step 214: In response to the received disconnection repair instruction, the calling system sends a disconnection repair service request to the disconnection repair system.

[0110] Step 216: In response to the loss of connection repair service request, the loss of connection repair system sends confirmation information to the second called party terminal.

[0111] In this step, the disconnection repair system responds to the disconnection repair service request by sending a confirmation message to the second called terminal, which includes the de-identified information corresponding to the calling terminal.

[0112] In this embodiment of the invention, step 216 is followed by:

[0113] Step S1: The second called terminal responds to the confirmation information and receives the user's input instruction to refuse repair.

[0114] Step S2: The second called party terminal sends a rejection repair command to the disconnection repair system.

[0115] Step S3: In response to the rejection repair command, the disconnection repair system sends a rejection message to the calling terminal.

[0116] Step 218: The second called terminal responds to the confirmation information and receives the confirmation repair command input by the user.

[0117] In this step, the second called party's terminal provides feedback to confirm whether to perform a connection loss repair. If a connection loss repair is performed, the user enters a confirmation repair command through the second called party's terminal.

[0118] Step 220: The second called party terminal sends a confirmation repair command to the disconnection repair system.

[0119] Step 222: In response to the confirmation repair command, the lost contact repair system sends the phone number corresponding to the second called party terminal to the calling party terminal.

[0120] As an optional solution, in response to the confirmation of the repair command, the lost contact repair system sends the de-identified information and phone number of the second called party terminal to the calling party terminal.

[0121] In the technical solution provided by this invention, the calling system, in response to the received loss-of-connection repair instruction, sends a loss-of-connection repair service request to the loss-of-connection repair system; the loss-of-connection repair system, in response to the loss-of-connection repair service request, sends confirmation information to the second called party terminal; the second called party terminal, in response to the confirmation information, receives a confirmation repair instruction input by the user; the second called party terminal sends a confirmation repair instruction to the loss-of-connection repair system; and the loss-of-connection repair system, in response to the confirmation repair instruction, sends the phone number corresponding to the second called party terminal to the calling party terminal. The technical solution provided by this invention can provide real-time loss-of-connection repair guidance when a user dials a phone number, and can directly confirm the loss-of-connection status and repairability based on the called party's feedback, thus improving the accuracy and security of loss-of-connection repair.

[0122] The technical solution provided in this invention can perform contact loss analysis and provide repair guidance based on users, phone numbers, and communication records, which is more accurate than contact loss repair derived from related person / enterprise information.

[0123] The technical solution provided in this invention provides a real-time and efficient method for determining potential loss of contact when dialing a lost phone number.

[0124] The technical solution provided in this invention can provide real-time repair guidance when making a call, and can directly confirm the lost contact status and repairability based on the feedback from the called party, which is accurate and efficient.
