Description

Technical Field

[0001] The present application belongs to the field of communication technology and mainly relates to a terminal identity identification method and related devices. Background Art

[0002] At present, the main function of terminal identity recognition is to prevent third-party telephone terminals from accessing the network and reduce the risk of terminal equipment leakage. As people pay more attention to the confidentiality of communication information, they also pay more and more attention to the confidentiality methods of communication information.

[0003] In the prior art, general telephones use digital encryption to encrypt to prevent leakage, but this method has poor confidentiality effect. Summary of the invention

[0004] One purpose of the present application is to provide a method and related device for terminal identity identification, the advantage of which is that the confidentiality of the terminal phone is greatly improved.

[0005] To achieve the above objectives, in a first aspect, an embodiment of the present application provides a method for terminal identity identification, comprising:

[0006] When the terminal phone goes off-hook to make a call, receiving the identity code of the terminal phone;

[0007] Verify whether the identification code is correct;

[0008] When the identity recognition code is verified to be correct, the communication line is connected.

[0009] It can be understood that when the terminal phone is off-hook for a call, the identity identification code of the terminal phone is received and the identity identification code is verified to be correct. When the identity identification code is verified to be correct, the communication line is connected, which can improve the confidentiality of the terminal phone.

[0010] In a possible example, the terminal phone has two states: an off-hook state and an on-hook state, and an interrupt pin is used to control the off-hook state and the on-hook state.

[0011] It can be understood that using the interrupt pin to control the off-hook state and the on-hook state can optimize the control efficiency of off-hook and on-hook.

[0012] In a possible example, verifying whether the identity code is correct includes:

[0013] Use the first output pin to indicate the authentication state and non-authentication state;

[0014] Use the second output pin to control the power switch;

[0015] Use the third output pin to control the on and off of the line.

[0016] It can be understood that using the first output pin to indicate the authentication state and the non-authentication state, using the second output pin to control the power switch, and using the third output pin to control the on-off of the circuit can improve the verification efficiency of the identity identification code.

[0017] In a possible example, verifying whether the identity code is correct includes:

[0018] When entering the authentication mode for the first time, the second output pin is turned off and the third output pin is turned on;

[0019] When entering the on-hook state, the second output pin is turned off, and the third output pin is turned on.

[0020] It can be understood that when entering the authentication mode for the first time, the second output pin is closed and the third output pin is turned on. When entering the on-hook state, the second output pin is closed and the third output pin is turned on, which can optimize the verification efficiency of the identity identification code.

[0021] In a possible example, when the telephone in the authentication state is connected for the first time, the first output pin has a low level for 2 seconds and then remains at a high level.

[0022] It can be understood that when the telephone in the authentication state is connected for the first time, the first output pin has a low level for 2 seconds and then remains at a high level, which can improve the design process of the authentication state.

[0023] In a possible example, when the non-authenticated phone is connected, the first output pin is always at a high level.

[0024] It can be understood that when the telephone in the non-authentication state is connected, the first output pin is always at a high level, which can improve the design process of the non-authentication state.

[0025] In a possible example, when the identity identification code is verified to be correct, before the communication line is connected, the following steps are included:

[0026] When the terminal phone is in the on-hook state and the terminal phone is called and goes off-hook, in a non-timeout state, receiving the identity identification code of the terminal phone;

[0027] Identity verification is performed based on the identity identification code.

[0028] It can be understood that when the terminal phone is on-hook and the terminal phone is called and goes off-hook, the identity code of the terminal phone is received before timeout, and identity authentication is performed based on the identity code, which can optimize the process of connecting the communication line.

[0029] In a second aspect, a terminal identity recognition device includes a module for executing the method provided in the first aspect or any implementation manner of the first aspect.

[0030] In a third aspect, a device for terminal identity identification is provided, characterized in that it comprises a processor, a memory and one or at least one program, wherein the one or at least one program is stored in the memory and is configured to be executed by the processor, and the program comprises instructions for executing the method provided in the first aspect or any embodiment of the first aspect.

[0031] In a fourth aspect, a computer-readable storage medium is provided, characterized in that the computer-readable storage medium stores a computer program, and the computer program enables a computer to execute to implement the method provided in the first aspect or any embodiment of the first aspect.

[0032] Implementing the embodiments of the present application will have the following beneficial effects:

[0033] When the terminal phone is off-hook for a call, the identity identification code of the terminal phone is received to verify whether the identity identification code is correct. When the identity identification code is verified to be correct, the communication line is connected, which greatly improves the confidentiality effect of the terminal phone.

[0049] The following describes a method for terminal identity recognition provided in an embodiment of the present application. The method can be executed by a terminal identity recognition device, which can be implemented by software and / or hardware and can generally be integrated in an electronic device or a server.

[0050] Please refer to Figure 2 , Figure 2 A schematic diagram of a process of terminal identity recognition provided in an embodiment of the present application. Taking the method applied to the terminal identity recognition process as an example, the terminal identity recognition device may include a server or an electronic device. The method includes the following steps S201-S203, wherein:

[0051] S201: When a terminal phone is off-hook for a call, an identity code of the terminal phone is received.

[0052] In the embodiment of the present application, there are two situations of the above-mentioned off-hook, one is to pick up the handset of the telephone, and the other is to press the hands-free mode, and the state at this time is the off-hook state. In the telecommunications network, the user who initiates the call is called the caller. If the local phone is used as the caller, the called party can be called. The call establishment command is issued by the caller, which indicates that the caller wants to establish a connection with the called party. The caller needs to make a call, and the switching network establishes a physical data path between the caller and the called party, and the transmission resources of the network are fixedly allocated for use by the communicating parties. During the connection of the physical data path between the caller and the called party, other users cannot use the transmission resources. When the connection needs to be removed, it is completed by either of the communicating parties, and the switching network releases the transmission resources occupied by it.

[0053] In a possible example, step S201 includes the following steps:

[0054] The terminal phone has two states: an off-hook state and an on-hook state, and an interrupt pin is used to control the off-hook state and the on-hook state.

[0055] In the embodiment of the present application, in the task power-on initialization stage designed by the terminal identity recognition software, the main processing is related to the pins and registers. This part is only executed during power-on initialization, and the processing pin status is as follows: the second output pin is set to a low level, the power is turned off; the third output pin is set to a low level, and the line is turned on. In the task startup stage, the task startup mainly realizes the related control pins of opening the authentication, and determines whether the relationship between the terminal identity recognition device and the customized phone is in authentication mode or normal mode. The processing flow is as follows:

[0056] 1) Determine whether the line is in the off-hook state. If the line is in the off-hook state, execute the process below. If the line is in the on-hook state, exit the process directly;

[0057] 2) Turn on the power switch of the terminal identity recognition device;

[0058] 3) Conducting circuit;

[0059] 4) Determine whether there is a continuous low level for 2 seconds within 5 seconds. If so, it is considered to be authentication mode and the state of the terminal identity recognition device is set to authentication mode. Otherwise, it is considered to be normal mode and the state of the device is set to normal mode.

[0060] S202: Verify whether the identity identification code is correct.

[0061] In a possible example, step S202 includes the following steps A1-A3, wherein:

[0062] A1: Use the first output pin to indicate the authentication state and non-authentication state.

[0063] In a possible example, step A1 includes the following steps A11-A12:

[0064] A11: When the telephone in the authentication state is connected for the first time, the first output pin has a low level for 2 seconds and then remains at a high level.

[0065] A12: When the non-authenticated phone is connected, the first output pin is always at a high level.

[0066] A2: Use the second output pin to control the power switch.

[0067] A3: Use the third output pin to control the on / off of the circuit.

[0068] In a possible example, step S202 includes the following steps:

[0069] When entering the authentication mode for the first time, the second output pin is turned off and the third output pin is turned on;

[0070] When entering the on-hook state, the second output pin is turned off, and the third output pin is turned on.

[0071] S203: When the identity identification code is verified to be correct, the communication line is connected.

[0072] In a possible example, step S203 includes the following steps:

[0073] When the terminal phone is in the on-hook state and the terminal phone is called and goes off-hook, in a non-timeout state, receiving the identity identification code of the terminal phone;

[0074] Identity verification is performed based on the identity identification code.

[0075] In the embodiments of the present application, the full name of IMS is IP Multimedia Subsystem, which is a network architecture that provides voice and multimedia services based on IP networks. It was originally designed by the 3G standardization organization 3GPP. As part of the future mobile network vision, the initial version of IMS mainly provides a method for implementing IP multimedia services based on GPRS. On the basis of this version, further updates have been made to support other access networks besides GPRS. From the current point of view, IMS is independent of access network technology, and the IP multimedia core network system is composed of all core network functional entities that can provide multimedia services, including a collection of functional entities related to signaling and bearer. In terms of control mode, IMS adopts a home control mode. For mobile users, through home control, even if the user roams to another place, they can enjoy the same services as the home place. In addition, IMS adopts access independence, provides excellent integration characteristics, and the service, control and bearer layers are completely separated. IMS further develops the idea of ​​separation of services and control, and separation of control and bearer in the soft switch structure. Compared with soft switch, it has more complete network decoupling, and the network structure is clearer and more reasonable. At the same time, the decoupling of different types of networks also creates conditions for the re-aggregation of networks at different levels.

[0076] In summary, the PSTN identity recognition in the embodiment of the present application is divided into two types: calling identity recognition and called identity recognition. During the calling identity recognition, the ordinary IMS intelligent terminal sends an identity recognition code to the adapter after picking up the phone. After the adapter receives the identity recognition code and confirms that it is correct, the adapter connects the communication line between the PSTN program-controlled switch and the ordinary IMS intelligent terminal. If other ordinary telephones access the PSTN line and actively pick up the phone, since the ordinary telephone does not send the identity recognition code to the adapter, the adapter cannot receive the identity recognition code authentication information, and this ordinary telephone cannot make a call. During the called identity recognition, the ordinary IMS intelligent terminal is in the on-hook state, the PSTN program-controlled switch sends a ringing signal, the adapter receives the ringing signal and the call information is transparently transmitted to the ordinary IMS intelligent terminal, and the ordinary IMS intelligent terminal sends the identity recognition code to the adapter at the moment of picking up the phone. After the adapter receives the identity recognition code and confirms that it is correct, it will connect the communication line between the PSTN program-controlled switch and the ordinary IMS intelligent terminal. If a regular phone is connected to the PSTN line, the adapter will cut off the communication line between the regular phone and the PSTN program-controlled switch because no identification code will be sent to the adapter after the phone is picked up. Therefore, the regular phone cannot be used on the line equipped with the adapter.

Based on the above system architecture, the hardware design block diagram at least includes: a microprocessor 301, a terminal side codec unit 302, a switch side codec unit 303, a power management unit 304 and a modem interface 305.

[0078] See also Figure 4 , Figure 4 A flow chart of a task startup software design provided in an embodiment of the present application. Figure 4 As shown, it may include steps S401 to S408.

[0079] Step S401: Start.

[0080] Step S402: Whether to pick up the phone.

[0081] Step S403: Turn on the power supply to connect the circuit.

[0082] Step S404: Whether 5s has arrived.

[0083] Step S405: Whether the high level lasts for 2s.

[0084] Step S406: Authentication mode.

[0085] Step S407: Normal mode.

[0086] Step S408: End.

[0087] See also Figure 5 , Figure 5 A timing diagram of the pin control of the authentication mode provided in the embodiment of the present application. When entering the authentication mode for the first time, the call line is not cut off, that is, the second output pin is closed and the third output pin is turned on, and it is maintained until the line phone is hung up, the second output pin is closed, the third output pin is turned on, and the next authentication detection process is entered.

[0088] See also Figure 6 , Figure 6A timing diagram of a normal mode pin control provided for an embodiment of the present application. The first step is to enter the normal mode for the first time, the second output pin is turned on, and the third output pin is disconnected. The second step is to close the second output pin and turn on the third output pin after five seconds. At this time, a delay of 200ms is required to keep the switch stable and detect whether the phone is in the off-hook state. If it is still in the off-hook state, the polling detection executes the first and second steps. When the line phone is hung up, the second output pin is closed and the third output pin is turned on, and the next authentication detection process is entered. The purpose of cyclically executing the first and second steps is that when the second output pin is turned on and the third output pin is disconnected, the interrupt pin is always at a high level regardless of whether the line phone is on or off-hook. In order to monitor whether the line phone is actually on-hook, the second step is executed to further detect the interrupt pin.

[0091] The verification module 702 is used to verify whether the identity identification code is correct;

[0092] The processing module 703 is used to connect the communication line.

[0093] In a possible example, the terminal phone has two states: an off-hook state and an on-hook state, and the processing module 703 uses an interrupt pin to control the off-hook state and the on-hook state.

[0094] In a possible example, the processing module 703 uses a first output pin to indicate an authentication state and a non-authentication state, uses a second output pin to control a power switch, and uses a third output pin to control the on / off of a circuit.

[0095] In a possible example, when the processing module 703 enters the authentication mode for the first time, the second output pin is turned off and the third output pin is turned on; when entering the on-hook state, the second output pin is turned off and the third output pin is turned on.

[0096] In a possible example, when the telephone in the authentication state is connected for the first time, the processing module 703 causes the first output pin to have a low level for 2 seconds and then remain at a high level.

[0097] In a possible example, when the non-authenticated phone is connected, the first output pin of the processing module 703 is always at a high level.

[0098] In a possible example, when the terminal phone is on-hook and the terminal phone is called and goes off-hook, in a non-timeout state, the receiving module 701 receives the identity identification code of the terminal phone, and the verification module 702 performs identity authentication based on the identity identification code.

[0107] Use the second output pin to control the power switch;
