[0077] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0078] Figure 1 A schematic diagram of an application scenario of a network deregistration system provided in an embodiment of the present application. Figure 1 As shown, in this scenario, there are a first user terminal 100, a second user terminal 200 and an access network device 300. The first user terminal 100 and the second user terminal 200 perform data transmission via a network, and the first user terminal 100 and the access network device 300 perform data transmission via a network.

[0079] Among them, the access network device 300 can be a base station (Base Transceiver Station, BTS) in Global System of Mobilecommunication (GSM) or Code Division Multiple Access (CDMA), or a base station (NodeB, NB) in Wideband Code Division Multiple Access (WCDMA), or an evolved base station (Evolutional Node B, eNB or eNodeB) in LTE, or a relay station or access point, or a base station in a 5G network, etc., which is not limited here.

[0080] The first user terminal 100 and the second terminal 200 may be wireless terminals, which may be devices that provide voice and / or other service data connectivity to users, or handheld devices with wireless connection functions, or other processing devices connected to wireless modems. The wireless terminal may communicate with one or more core networks via a radio access network (Radio Access Network, referred to as RAN). The wireless terminal may be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, for example, a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device, which exchanges language and / or data with the radio access network. The wireless terminal may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, an access terminal, a user terminal, a user agent, a user device or user equipment, which is not limited here.

[0081] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0082] In one embodiment, Figure 2 As shown, a network deregistration system is provided, which may include a target core network element 200, a base station 202 and a terminal 204, wherein the target core network element 200 is used to deregister the terminal 204 associated with the target network when the target network meets the deregistration conditions, and send fault information to the base station 202 associated with the target network, wherein the fault information is used to indicate that the target network is in a disaster state; the base station 202 is used to broadcast the fault information; and the terminal 204 is used to receive the fault information and perform deregistration processing for the target network.

[0083] For example, the target core network element 200 may be any element in the core network, and the target core network element 200 is not specifically limited in the embodiment of the present disclosure. The target core network element 200 may detect whether the target network satisfies the deregistration condition, wherein the deregistration condition may include a condition for characterizing that the target network is in a disaster state or is about to enter a disaster state, and the target network is composed of a core network and a base station, and the core network is unavailable when the target network is in a disaster state.

[0084] When the target core network element 200 detects that the target network meets the deregistration conditions, it will perform deregistration processing on the terminal 204 associated with the target network, wherein the terminal 204 associated with the target network may include: a terminal registered in an area of ​​the target network that is in or is about to be in a disaster state, wherein the deregistration processing may include changing the registration status information of the terminal for the target network to deregistration.

[0085] After completing the deregistration process of the terminal, the target core network element 200 may send fault information to the base station associated with the target network, and the fault information may include the network identifier of the target network (such as the core network identifier and other information), so as to notify the base station that the target network is in or is about to be in a disaster state through the fault information. The base station 202 associated with the target network may include: a base station located in an area of ​​the target network that is in or is about to be in a disaster state.

[0086] In the disclosed embodiment, after receiving the fault information, the base station 202 may broadcast the fault information. After receiving the fault information, the terminal within the coverage of the base station may perform deregistration processing for the target network, that is, the registration status information of the terminal for the target network may be changed to deregistration.

[0087] With the network deregistration system provided by the embodiment of the present disclosure, when the target network meets the deregistration conditions, the target core network network element performs deregistration processing of the terminal associated with the target network, and sends fault information to the base station associated with the target network. After receiving the fault information, the base station broadcasts the fault information within the coverage area, and the terminal within the coverage area of ​​the base station performs deregistration processing for the target network after receiving the fault information. Since the terminal can perceive the network fault through the fault information and perform deregistration processing when or before the network fault, it can avoid the problem of service interruption caused by the terminal being unable to detect the core network fault, and can greatly improve the stability of network services.

[0088] In an exemplary embodiment, the deregistration condition includes: the core network element predicts that the target network will enter a disaster state, or the core network element receives alarm information for the target network.

[0089] In the disclosed embodiment, when the core network element predicts that the target network is about to enter a disaster state, it can be determined that the target network currently meets the deregistration condition, or when the core network element receives an alarm message for the target network, it can be determined that the target network currently meets the deregistration condition. Exemplarily, when it is predicted that the core network and / or the base station are about to fail, that is, about to enter a disaster state, or when corresponding alarm messages for the core network and / or the base station are received, it can be determined that the target network currently meets the deregistration condition.

[0090] It should be noted that the embodiments of the present disclosure do not specifically limit the method of predicting the network disaster state or implementing the network disaster alarm. Any method that can realize the prediction of the network disaster state or implement the network disaster alarm is applicable to the embodiments of the present disclosure.

[0091] In the disclosed embodiment, the core network element may be an element other than AMF (Access and Mobility Management Function). When the core network element predicts that the target network is about to enter a disaster state or the core network element receives an alarm message for the target network, the core network element may send a deregistration instruction to the target core network element, and the target core network element performs the deregistration process for the terminal associated with the target network. Exemplarily, when the target core network element is an element other than AMF, the target core network element may send a deregistration instruction to AMF, and instruct AMF to perform the deregistration process for the terminal associated with the target network through the deregistration instruction.

[0092] In an exemplary embodiment, the target core network element 200 includes an access and mobility management function AMF, and the AMF deregisters the terminal associated with the target network when the target network meets the deregistration conditions.

[0093] In the disclosed embodiment, when the target network has failed but the access and mobility management function AMF has not failed, the target core network network element 200 may be AMF. When the AMF detects that the target network meets the deregistration condition, it may directly deregister the terminal associated with the target network, that is, change the registration status information of the terminal for the target network to deregistration.

[0094] In an exemplary embodiment, when a target network has failed but the access and mobility management function AMF has not failed, the deregistration conditions include: the AMF detects that the target network has entered a disaster state, or the AMF receives a prompt message indicating that the target network is about to enter a disaster state.

[0095] In the disclosed embodiment, when a fault has occurred in the target network but the access and mobility management function AMF has not failed, the target core network network element may be an AMF. When the AMF detects that the target network has entered a disaster state, it can be determined that the target network currently meets the deregistration conditions, or when the AMF receives a prompt message indicating that the target network is about to enter a disaster state, it can be determined that the target network currently meets the deregistration conditions. Exemplarily, when the AMF detects that a fault has occurred in the core network, that is, the core network has entered a disaster state, or receives a prompt message indicating that the core network and / or the base station is about to enter a disaster state, it can be determined that the target network currently meets the deregistration conditions.

[0096] It should be noted that the embodiments of the present disclosure do not specifically limit the method of detecting a network disaster state or implementing a network disaster prompt. Any method that can implement network disaster state detection or implement a network disaster prompt is applicable to the embodiments of the present disclosure.

[0097] In an exemplary embodiment, the base station 202 is further configured to broadcast fault information in an area of ​​the target network that is in a disaster state.

[0098] In the disclosed embodiment, the target network may be faulty within a certain range, so the fault information may include the area where the target network has a fault, that is, the area in the target network that is in a disaster state. After receiving the fault information, the base station 202 may broadcast the fault information in the area in the disaster state, so that the terminal 204 registered in the disaster state area may deregister with respect to the target network after receiving the fault information, so as to avoid interference with other terminals.

[0099] In an exemplary embodiment, the fault information includes an identification of the target network.

[0100] In an exemplary embodiment, the terminal 204 is further configured to parse the target network identifier carried in the fault information, determine the target network according to the target network identifier, and perform deregistration processing for the target network if the terminal has been registered with the target network.

[0101] In this way, after receiving the fault information, the terminal can determine whether to register in the target network according to the identifier of the target network carried in the fault information, and when it is determined to be registered in the target network, perform deregistration processing for the target network, or ignore the fault information when it is determined not to be registered in the target network. In this way, only the terminals registered in the target network can be deregistered to avoid interference with other terminals.

[0102] In an exemplary embodiment, the deregistration process includes: updating the registration state information to deregistration.

[0103] In order to enable those skilled in the art to better understand the embodiments of the present disclosure, the embodiments of the present disclosure are described below through specific examples.

[0104] Reference Figure 3 As shown, in a scenario where the base station and / or core network constituting the target network is about to fail, the terminal is registered with the PLMN (Public Land Mobile Network) before the failure causes the PLMN service to be interrupted. The target core network network element predicts that the target network is about to have a network failure (the base station and / or core network is about to fail), or receives an alarm message that the target network is about to have a network failure. At this time, the AMF can change the registration status information associated with the terminal affected by the failure to deregister, and notify the base stations in the area affected by the failure. The base station broadcasts the relevant fault message in the area affected by the fault, and the terminal receives the fault message from the broadcast channel and changes the registration status information to deregister.

[0105] Reference Figure 4 As shown, in a scenario where the core network constituting the target network has failed but the AMF has not failed, the terminal is registered in the PLMN network before the failure causes the PLMN service to be interrupted. The AMF works normally and detects a network failure (the base station and / or the core network is about to fail), or receives a fault message that the target network is about to have a network failure. The AMF can change the registration status information associated with the terminal affected by the fault to deregistration. And notify the base stations in the fault-affected area. The base station broadcasts the relevant fault message in the fault-affected area. The terminal receives the fault message from the broadcast channel and changes the registration status information to deregistration.

[0106] In the network deregistration system provided by the embodiment of the present disclosure, before the service of the resident network is interrupted due to a fault, the base station broadcasts a related fault message in the fault-affected area, and the terminal receives the fault message and changes the registration status information to deregistration. The target core network element serving the terminal changes the registration status information associated with the terminal to deregistration, and the target core network element includes the AMF.

[0107] In one embodiment, Figure 5 As shown, a network deregistration method is provided, which can be applied to a core network element. The method may include:

[0108] In step 502, when the target network meets the deregistration condition, deregistration processing of the terminal associated with the target network is performed;

[0109] In step 504, the fault information is sent to a base station associated with the target network, so that the base station broadcasts the fault information and instructs the terminal to perform a deregistration process for the target network.

[0110] In the disclosed embodiment, when the core network element detects that the target network meets the deregistration conditions, it can deregister the terminals associated with the target network, where the terminals associated with the target network include: terminals registered in the area of ​​the target network that is in a disaster state.

[0111] In an exemplary embodiment, the above method may further include:

[0112] When it is predicted that the target network will enter a disaster state, or when an alarm message for the target network is received, determining that the target network meets the deregistration condition; or,

[0113] When it is detected that the target network enters a disaster state, or when prompt information indicating that the target network is about to enter a disaster state is received, it is determined that the target network satisfies the deregistration condition.

[0114] In the disclosed embodiment, when the core network element predicts that the target network is about to enter a disaster state or receives an alarm message for the target network, it can be considered that the core network element meets the deregistration condition. Alternatively, when the core network element is an AMF, when the AMF detects that the target network has entered a disaster state, or the AMF receives a prompt message indicating that the target network is about to enter a disaster state, it can be determined that the target network meets the deregistration condition.

[0115] When determining that the target network meets the deregistration condition, the core network element may send fault information to the base station associated with the target network, so that the base station broadcasts the fault information, so that the terminal receiving the fault information performs deregistration processing for the target network. The base station associated with the target network may include: a base station located in an area in a disaster state in the target network.

[0116] In an exemplary embodiment, the deregistration process may include: updating the registration status information of the terminal for the target network to deregistration.

[0117] Exemplarily, when the core network element determines that the target network meets the de-registration conditions, the core network element may send a de-registration instruction to the AMF, and the AMF may change the registration status information of the terminal for the target network to de-registration. Alternatively, when the core network element is the AMF, when the AMF determines that the target network meets the de-registration conditions, the AMF may change the registration status information of the terminal for the target network to de-registration.

[0118] After receiving the fault information, the terminal may change the registration status information for the target network to deregistration.

[0119] By adopting the network deregistration method provided by the embodiment of the present disclosure, when the target network meets the deregistration conditions, the core network network element performs deregistration processing of the terminal associated with the target network, and sends fault information to the base station associated with the target network. After receiving the fault information, the base station broadcasts the fault information within the coverage area. After receiving the fault information, the terminal within the coverage area of ​​the base station performs deregistration processing for the target network. Since the terminal can perceive the network fault through the fault information and perform deregistration processing when the network fails, it can avoid the problem of service interruption caused by the terminal being unable to detect the core network fault, which can greatly improve the stability of network services.

[0120] In one embodiment, Figure 6 As shown, a network deregistration method is provided, which can be applied to a terminal. The method may include:

[0121] Step 602, receiving fault information, where the fault information is information broadcast by the target core network element through the base station when the target network meets the deregistration condition, and the fault information is used to indicate that the target network is in a disaster state;

[0122] Step 604: Execute deregistration processing for the target network.

[0123] In the disclosed embodiment, the deregistration conditions include: the core network element predicts that the target network will enter a disaster state, or the core network element receives alarm information for the target network; or, when the target network has failed but the access and mobility management function AMF has not failed, the deregistration conditions include: AMF detects that the target network has entered a disaster state, or AMF receives prompt information indicating that the target network is about to enter a disaster state.

[0124] Exemplarily, when the core network element predicts that the target network is about to enter a disaster state or receives an alarm message for the target network, it can be considered that the core network element meets the deregistration condition. Alternatively, when the core network element is an AMF, when the AMF detects that the target network has entered a disaster state, or the AMF receives a prompt message indicating that the target network is about to enter a disaster state, it can be determined that the target network meets the deregistration condition.

[0125] When determining that the target network meets the deregistration condition, the core network element may send fault information to the base station associated with the target network so that the base station broadcasts the fault information. The terminal receiving the fault information within the coverage of the base station may perform deregistration processing for the target network. The base station associated with the target network may include: a base station located in an area in a disaster state in the target network.

[0126] In an exemplary embodiment, the above-mentioned deregistration process for the target network may include:

[0127] Update the registration status information for the target network to deregister.

[0128] In an exemplary embodiment, the fault information includes an identifier of a target network, and performing a deregistration process for the target network may include:

[0129] Determining registration status information for the target network according to the identifier of the target network;

[0130] When the registration status information for the target network is registered, a deregistration process for the target network is performed.

[0131] In the disclosed embodiment, the fault information includes an identifier of the target network. The terminal is further configured to parse the identifier of the target network carried in the fault information, determine the target network and registration status information for the target network according to the identifier of the target network, and if the registration status information for the target network is registered, change the registration status information to deregistered.

[0132] By adopting the network deregistration method provided by the embodiment of the present disclosure, when the target network meets the deregistration conditions, the core network network element performs deregistration processing of the terminal associated with the target network, and sends fault information to the base station associated with the target network. After receiving the fault information, the base station broadcasts the fault information within the coverage area. After receiving the fault information, the terminal within the coverage area of ​​the base station performs deregistration processing for the target network. Since the terminal can perceive the network fault through the fault information and perform deregistration processing when the network fails, it can avoid the problem of service interruption caused by the terminal being unable to detect the core network fault, which can greatly improve the stability of network services.

[0133] The disclosed embodiment proposes a network deregistration method, whereby a terminal can deregister from a faulty network according to a broadcast fault message before service interruption and execute subsequent disaster recovery measures, thereby solving the problem that when a core network fails, wireless connections are not affected, and the terminal cannot detect the network failure, resulting in a long service interruption. At the same time, the workflow of the terminal, base station, and core network element before service interruption is defined, thereby improving the network's disaster recovery mechanism.

[0134] It should be understood that although Figure 1-6 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 1-6 At least part of the steps may include multiple steps or multiple stages. These steps or stages are not necessarily performed at the same time, but can be performed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed in turn or alternately with other steps or at least part of the steps or stages in other steps.
