[0072] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0073] The network sharing method provided in this application embodiment can be applied to, for example, Figure 1 In the application environment shown, the first AMF (Active Base Function) element of the shared operator network sends an emergency instruction request to the second AMF element of the home operator network in advance. The second AMF element monitors the base station status of the first base station of the home operator network, determines the emergency state entry status based on the base station status, and sends an emergency instruction response message to the first AMF element if the emergency state entry status is "entering emergency state." Upon receiving the emergency instruction response message, the first AMF element controls the second base station of the shared operator network to enable shared services, allowing user terminals of the home operator network to access the shared operator network via the second base station.

[0074] In this context, the home operator network refers to an operator network with network sharing requirements. The shared operator network refers to an operator network that provides network sharing services. In this application, the home operator network and the shared operator network can be networks in different regions of the same operator, or they can be networks of different operators.

[0075] The AMF (Access and Mobility Management Function) network element is mainly responsible for functions such as user terminal authentication, authorization, registration, mobility management, and connection management.

[0076] Base stations are a key component of wireless communication networks. They are points for transmitting and receiving radio signals and are used to communicate with mobile devices such as mobile phones, tablets, and IoT devices.

[0077] In one embodiment, Figure 2 This is a flowchart illustrating a network sharing method provided in an embodiment of this application, which is applied to... Figure 1 Taking the first AMF network element as an example, the method includes the following steps:

[0078] S201, send an emergency instruction request to the second AMF network element belonging to the operator's network.

[0079] The emergency instruction request is used to instruct the second AMF network element to monitor the base station status of the first base station in the home operator network, determine the emergency state entry status based on the base station status, and send an emergency instruction response message to the first AMF network element if the emergency state entry status is "entering an emergency state." The home operator network refers to an operator network with network sharing needs. The sharing operator network refers to an operator network providing network sharing services. In this application, the home operator network and the sharing operator network can be networks in different regions of the same operator, or networks of different operators. The first AMF network element refers to the AMF network element of the sharing operator network. The second AMF network element refers to the AMF network element of the home operator network. The emergency instruction request is a request message that can provide network sharing services in emergency situations.

[0080] As an optional implementation of this application, an emergency instruction request is sent directly to the second AMF network element of the home operator network.

[0081] Another optional implementation of this application involves sending an emergency instruction request to a second AMF (Application-Specific Function) network element in the home operator network via a shared NRF (Network Repository Function) network element in the operator network and an NRF network element in the home operator network. Specifically, the first AMF network element sends the emergency instruction request to the shared NRF network element, the shared NRF network element sends the emergency instruction request to the home operator network NRF network element, and the home operator network NRF network element sends the emergency instruction request to the second AMF network element in the home operator network.

[0082] Optionally, in this embodiment, the first base station may be a base station device belonging to the operator's network.

[0083] Optionally, in this embodiment, one possible implementation for the second AMF network element to determine the emergency state entry status based on the base station status is to obtain the number of first base stations whose base station status is faulty. The emergency state entry status is then determined based on the number of base stations. Specifically, if the number of first base stations whose base station status is faulty is greater than a first threshold, the emergency state entry status is determined to be entering an emergency state.

[0084] S202, upon receiving an emergency instruction response message, controls the second base station of the shared operator network to enable the sharing service, so that user terminals belonging to the operator network can access the shared operator network based on the second base station.

[0085] Among them, the emergency instruction response message refers to the response message sent by the home operator network to the first AMF network element of the shared operator network when it determines that it has entered an emergency state.

[0086] Optionally, in this embodiment, the second base station can be a base station device sharing an operator's network.

[0087] In this embodiment, an optional implementation method is to control the second base station of the shared operator network to enable the sharing service so that the user terminal of the home operator network can access the shared operator network based on the second base station. This method involves controlling the second base station of the operator network to broadcast a shared network number so that the user terminal of the home operator network can access the second base station based on the shared network number, and thus access the shared operator network.

[0088] Optionally, in this embodiment, after the second base station controlling the shared operator network to enable the sharing service, an optional implementation of the network sharing method is to send an emergency sharing enable confirmation message to the second AMF network element to inform the second AMF network element that the sharing service has been enabled.

[0089] The aforementioned network sharing method involves sending an emergency instruction request to a second AMF (Advanced Management Function) network element belonging to the home operator network. This emergency instruction request instructs the second AMF network element to monitor the base station status of the first base station in the home operator network, determine the emergency state entry status based on the base station status, and, if the emergency state entry status is "entering an emergency state," send an emergency instruction response message to the first AMF network element. Upon receiving the emergency instruction response message, the second base station sharing the operator network is controlled to activate the sharing service, enabling user terminals in the home operator network to access the shared operator network via the second base station. In this application, the first AMF network element sharing the operator network sends an emergency instruction request to the second AMF network element in the home operator network, causing the second AMF network element to monitor the base station status of the first base station in the home operator network, determine the emergency state entry status based on the base station status, and, if the emergency state entry status is "entering an emergency state," send an emergency instruction response message to the first AMF network element. Upon receiving an emergency response instruction message, the first AMF network element controls the second base station of the shared operator network to activate the sharing service, enabling user terminals on the home operator network to access the shared operator network via the second base station. This not only achieves network sharing between the home operator network and the shared operator network but also significantly improves network sharing efficiency, effectively enhancing the stability of network communication services in disaster environments.

[0090] In one embodiment, to make the open area of ​​the shared network region of the shared operator network more precise and targeted, while reducing network resource waste, such as Figure 3As shown, an optional implementation of sending an emergency instruction request to the second AMF network element of the home operator network in S201 includes:

[0091] S301, determine the overlapping area between the shared operator network and the home operator network.

[0092] As an optional implementation of this application, the first AMF network element sends a region acquisition request to the querying device; wherein the region acquisition request carries network identifiers of the shared operator network and the home operator network. The querying device reports the overlapping area between the shared operator network and the home operator network to the first AMF network element.

[0093] As an optional implementation of this application, the first AMF network element obtains the network coverage range of the shared operator network and the network coverage range of the home operator network. Based on the network coverage ranges of the shared operator network and the home operator network, it determines the overlapping area between the shared operator network and the home operator network.

[0094] S302, send an emergency instruction request carrying area information of overlapping areas to the second AMF network element of the home operator's network.

[0095] Optionally, in this embodiment, the first AMF network element may send an emergency instruction request carrying regional information of the overlapping area directly or through other network element devices to the second AMF network element belonging to the operator's network.

[0096] Based on the above embodiments, the emergency instruction request is further used to instruct the second AMF network element to select a first base station associated with the overlapping area from candidate base stations of the home operator network based on regional information. In this embodiment, the first base station refers to a base station device of the home operator network whose base station coverage overlaps with the overlapping area.

[0097] Optionally, in this embodiment, the second base station is a base station associated with the overlapping area. That is, the second base station is a base station device of a shared operator network whose coverage area overlaps with the overlapping area.

[0098] In this embodiment, an overlapping area between the sharing operator network and the home operator network is determined. An emergency instruction request carrying area information of the overlapping area is sent to a second AMF network element of the home operator network. The emergency instruction request also instructs the second AMF network element to select a first base station associated with the overlapping area from candidate base stations of the home operator network based on the area information. In this embodiment, the first base station refers to the first base station associated with the overlapping area. That is, only the first base station associated with the overlapping area is controlled to enable the sharing service, making the opening of the sharing service more targeted. Since base stations in other areas cannot provide network services to user terminals of the home operator network even if they enable the sharing service, this embodiment only controls the first base station to enable the sharing service, avoiding the resource waste caused by other base stations enabling the sharing service.

[0099] In one embodiment, to enable the shared operator network to shut down shared services in a timely manner, thereby reducing network resource consumption and network load, such as Figure 4 As shown, an optional implementation of a network sharing method includes:

[0100] S401 receives an emergency sharing shutdown request sent by the second AMF network element.

[0101] The Emergency Share Shutdown Request refers to a request message that requests the sharing operator's network to shut down the shared service. The Emergency Share Shutdown Request is sent by the second AMF network element when, based on the base station status, it determines that the emergency state has transitioned from entering to exiting the emergency state.

[0102] Optionally, in this embodiment, one possible implementation for the second AMF network element to determine whether the emergency state entry status is an exit from the emergency state is to obtain the number of base stations of the first base station whose base station status is normal. If the number of base stations of the first base station whose base station status is normal is greater than a second threshold, the emergency state entry status is determined to be an exit from the emergency state.

[0103] S402, controls the second base station sharing the operator's network to shut down the shared service.

[0104] Optionally, in this embodiment, the second base station controlling the shared operator network stops broadcasting the shared network number. User terminals belonging to the home operator network can no longer access the shared operator network based on the shared network number, thus disabling the shared service.

[0105] S403 sends an emergency sharing shutdown response message to the second AMF network element when the shared service is shut down.

[0106] In this embodiment, an emergency sharing shutdown request is received from the second AMF network element. This request is sent by the second AMF network element after determining, based on the base station status, that the emergency state entry condition has changed to exiting the emergency state. The second base station of the shared operator network is controlled to shut down the sharing service. When the sharing service is shut down, an emergency sharing shutdown response message is sent to the second AMF network element. This embodiment allows the shared operator network to shut down the sharing service in a timely manner, reducing network resource consumption and network burden.

[0107] In one embodiment, Figure 5 This is a flowchart illustrating a network sharing method provided in an embodiment of this application, which is applied to... Figure 1 Taking the second AMF network element as an example, the method includes the following steps:

[0108] S501, upon receiving an emergency instruction request from the first AMF network element of the shared operator network, monitors the base station status of the first base station of the home operator network.

[0109] Optionally, in this embodiment, the emergency instruction request sent by the first AMF network element can be received by receiving the emergency instruction request sent by the first AMF network element through the NRF network element of the shared operator network and the NRF network element of the home operator network.

[0110] Optionally, in this embodiment, the first base station can be a base station device belonging to the operator's network, for example, all normally functioning base station devices.

[0111] Optionally, in this embodiment, the first base station may also be the first base station associated with the overlapping area selected by the second AMF network element from the candidate base stations based on the coverage of each candidate base station of the home operator network; wherein, the number of first base stations is at least one. That is to say, in this embodiment, the first base station refers to the base station equipment of the home operator network associated with the overlapping area.

[0112] Optionally, in this embodiment, the second AMF network element detects the base station status of the first base station by obtaining the status report sent by the first base station. The status report includes, but is not limited to, resource usage and base station operation status.

[0113] S502 determines the emergency state entry status based on the base station status.

[0114] Optionally, in this embodiment, the number of first base stations whose base station status is faulty can be obtained. Based on the number of base stations, the emergency state entry status is determined. Specifically, if the number of first base stations whose base station status is faulty exceeds a first threshold, the emergency state entry status is determined to be entering an emergency state.

[0115] S503, when the emergency state entry status is "entering emergency state", sends an emergency instruction response message to the first AMF network element.

[0116] Among them, the emergency instruction response message is used to instruct the first AMF network element of the shared operator network to control the second base station of the shared operator network to start the shared service, so that the user terminal of the home operator network can access the shared operator network based on the second base station.

[0117] Optionally, in this embodiment, the first AMF network element of the shared operator network controls the second base station of the shared operator network to enable the sharing service, so that user terminals belonging to the operator network can access the shared operator network based on the second base station. Alternatively, the second base station of the operator network can be controlled to broadcast a shared network number, allowing user terminals belonging to the operator network to access the second base station based on the shared network number, and thus access the shared operator network. Optionally, in this embodiment, the second base station can be a base station device of the shared operator network, for example, all normally functioning base station devices in the shared operator network. The second base station can also be a base station device of the shared operator network associated with the aforementioned overlapping area; that is, the second base station is a base station device in the shared operator network whose coverage overlaps with the overlapping area.

[0118] Optionally, in this embodiment, the second AMF network element may also receive an emergency sharing activation confirmation message sent by the first AMF network element; wherein, the emergency sharing activation confirmation message is sent by the first AMF network element after controlling the second base station of the sharing operator network to activate the sharing service.

[0119] Based on the above embodiments, after receiving the emergency sharing activation confirmation message sent by the first AMF network element, an optional implementation of network sharing is to send an emergency sharing deactivation request to the first AMF network element when the emergency state entry status is exiting the emergency state; this enables the first AMF network element to control the second base station of the sharing operator network to shut down the sharing service, and when the sharing service is shut down, to send an emergency sharing deactivation response message back to the second AMF network element. In other words, after receiving the emergency sharing activation confirmation message sent by the first AMF network element, the second AMF network element will continue to monitor the base station status of the first base station. In this embodiment, an optional implementation for the first AMF network element to determine whether the emergency state entry status is exiting the emergency state is to obtain the number of base stations of the first base station whose base station status is normal. If the number of base stations of the first base station whose base station status is normal is greater than a second threshold, the emergency state entry status is determined to be exiting the emergency state. Based on this embodiment, the sharing operator network can shut down the sharing service in a timely manner, reducing energy consumption and the network burden of the sharing operator network.

[0120] In this embodiment, upon receiving an emergency instruction request from the first AMF network element of the shared operator network, the base station status of the first base station of the home operator network is monitored. Based on the base station status, the emergency state entry status is determined. If the emergency state entry status is "entering emergency state," an emergency instruction response message is sent to the first AMF network element. This message instructs the first AMF network element of the shared operator network to control the second base station of the shared operator network to enable sharing services, allowing user terminals of the home operator network to access the shared operator network via the second base station. Based on this application, through the interaction of the first and second AMF network elements, network sharing is not only achieved between the home operator network and the shared operator network, but also the network sharing efficiency is significantly improved, effectively enhancing the stability of network communication services under disaster conditions.

[0121] In one embodiment, such as Figure 6 As shown, another optional implementation of a network sharing method includes:

[0122] S601, the first AMF network element determines the overlapping area between the shared operator network and the home operator network.

[0123] S602, the first AMF network element sends an emergency instruction request carrying area information of the overlapping area to the second AMF network element of the home operator network through the shared operator network NRF network element and the home operator network NRF network element.

[0125] S604, the second AMF network element monitors the base station status of the first base station belonging to the operator's network.

[0126] S605, the second AMF network element determines the emergency state entry status based on the base station status.

[0127] S606, when the emergency state entry status is "entering emergency state", the second AMF network element sends an emergency instruction response message to the first AMF network element.

[0128] S607, upon receiving an emergency instruction response message, the first AMF network element controls the second base station of the shared operator network to enable the sharing service, so that user terminals belonging to the operator network can access the shared operator network based on the second base station.

[0130] S609, the second AMF network element receives the emergency sharing activation confirmation message sent by the first AMF network element.

[0132] S611, the first AMF network element controls the second base station of the shared operator network to shut down the shared service.

[0133] S612, when the shared service is shut down, the first AMF network element sends an emergency shared service shutdown response message to the second AMF network element.

[0134] In this embodiment, an emergency instruction request is sent to the second AMF network element of the home operator network. The emergency instruction request instructs the second AMF network element to monitor the base station status of the first base station of the home operator network, determine the emergency state entry status based on the base station status, and, if the emergency state entry status is "entering an emergency state," send an emergency instruction response message to the first AMF network element. Upon receiving the emergency instruction response message, the second base station of the shared operator network is controlled to enable shared services, allowing user terminals of the home operator network to access the shared operator network via the second base station. In this application, the first AMF network element of the shared operator network sends an emergency instruction request to the second AMF network element of the home operator network, enabling the second AMF network element to monitor the base station status of the first base station of the home operator network, determine the emergency state entry status based on the base station status, and, if the emergency state entry status is "entering an emergency state," send an emergency instruction response message to the first AMF network element. Upon receiving an emergency response instruction message, the first AMF network element controls the second base station of the shared operator network to activate the sharing service, enabling user terminals on the home operator network to access the shared operator network via the second base station. This not only achieves network sharing between the home operator network and the shared operator network but also significantly improves network sharing efficiency, effectively enhancing the stability of network communication services in disaster environments.
