Before describing the disaster recovery processing method of the embodiment of the present application in detail, an implementation environment and an application field Jing Jinhang of the embodiment of the present application are described.
First, an application scenario of the embodiment of the present application is described.
The disaster recovery processing method of the embodiment of the application is applied to the scene of disaster recovery of core network equipment. For public network user terminals, the implementation of the service is not greatly affected by the disaster recovery in different places (namely, the service is carried by disaster recovery DC). When the double main DCs in one area have a fault at the same time, the disaster recovery DCs have the capacity of taking over all the services in the area. Wherein the dual main DC may be generally referred to as a first DC and a second DC, and the disaster tolerant DC may be referred to as a third DC.
Illustratively, as shown in fig. 1A, zone a includes a province a and a province B, with the traffic of zone a being carried by a primary DC101 and a primary DC102, each DC comprising: SMF network elements, AMF network elements, network storage function (Network Repository Function, NRF) network elements, and user plane function (User Plane Function, UPF) network elements, etc. When both the main DC101 and the main DC102 fail, the base station 103 corresponding to the a-province may be connected to the disaster recovery DC104, and obtain user authentication and subscription data from the UDM network element of the disaster recovery DC 104. And, the SMF network element of the disaster recovery DC104 may forward the user plane traffic carried by the UPF network element corresponding to the a-province according to the tracking area Code (TRACKING AREA Code, TAC), so that the disaster recovery DC104 carries the service of the a-province.
However, when the disaster recovery DC is used for processing the service, the disaster recovery DC is the DC deployed in other areas, so that the distance between the disaster recovery DC and the base station is long, the time for transmitting the service data is increased, and the time delay of processing the service by the disaster recovery DC is further increased. Thus, when the disaster recovery DC is used for processing the low-delay service under the condition that two main DCs are in fault, the normal operation of the service can be influenced.
In order to solve the above problems, an embodiment of the present application provides a disaster recovery processing method. In the method, under the condition that the double main DCs have faults, the disaster recovery DCs can start private network AMF network elements (also called AMF network elements in the lightweight core network), and the distance between the private network AMF network elements and the base station is smaller than the distance between the disaster recovery DCs and the base station. After receiving the message that the private network AMF network element has been enabled, the base station may then send service data to the private network AMF network element. In general, the distance between the private network AMF network element and the base station is relatively short, so that the time for transmitting service data can be shortened (or the processing speed of the private network AMF network element is relatively high). Therefore, the time for processing service data by the private network DC can be shortened, the time delay of the service is reduced, and the normal operation of the service is ensured.
The following describes an implementation environment of an embodiment of the present application.
As shown in fig. 1B, a communication system according to an embodiment of the present application includes a plurality of network devices, where the plurality of network devices may include: base station 105, disaster-tolerant DC106, private network DC107, base station 105, disaster-tolerant DC106, private network DC107 may be connected by a wire.
The base station may include various forms of base stations, such as: macro base stations, micro base stations (also referred to as small stations), relay stations, access points, and the like. The method specifically comprises the following steps: an Access Point (AP) in a wireless local area network (Wireless Local Area Network, WLAN), a base station (Base Transceiver Station, BTS) in a global system for mobile communications (Global System for Mobile Communications, GSM) or code division multiple access (Code Division Multiple Access, CDMA), a base station (NodeB, NB) in wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA), an Evolved Node B (eNB or eNodeB) in LTE, a relay station or access point, a vehicle device, a wearable device, a next generation Node B (The Next Generation Node B, gNB) in a future 5G network, a base station in a future Evolved public land mobile network (Public Land Mobile Network, PLMN) network, or the like.
Embodiments of the present application will be described in detail below with reference to the drawings attached to the specification.

S201, the access network equipment sends a fault message to the disaster recovery AMF network element.
The fault message is used for indicating that a main core network device connected with the access network device fails, and the disaster tolerant AMF network element is an AMF network element of the disaster tolerant DC.
In the embodiment of the present application, the primary core network device connected to the access network device refers to a core network device that carries services in the access network device. That is, in the case where the primary core network device connected to the access network device does not fail, the service data transmitted by the access network device is processed by the primary core network device.
S202, the disaster recovery AMF network element receives a fault message from the access network equipment.
S203, the disaster recovery AMF network element sends a second message to the private network AMF network element.
The second message is used for indicating to start the private network AMF network element.
In one possible implementation, address information of the private network AMF network element is stored in the disaster recovery AMF network element. The disaster recovery AMF network element may send the second message to the private network AMF network element according to the address information of the private network AMF network element.
In one possible design, the second message may include first information indicating a cause of enabling the private network AMF network element.
It should be noted that, the embodiment of the present application does not limit the representation form of the first information. For example, the first information may be represented by a number. For another example, the first information may be represented by letters. For another example, the first information may be represented by a mixture of numbers, letters, etc.
Illustratively, if the first information is a first value (e.g., 0), it is explained that the reason for enabling the private network AMF network element is that the primary DC is powered down. Or if the first information is a second value (e.g. 1), it is stated that the reason for enabling the private network AMF network element is that the primary DC has network failure.
Alternatively, the second message may be Namf _communication_ Authorization Request, namf _communication_ Authorization Request may include Establish mentCause.
Optionally, the second message may further include authentication information, where the authentication information is used to verify the AMF network element of the private network.
Accordingly, the private network AMF network element may receive the second message from the disaster tolerant AMF network element.
In some embodiments, the private network AMF element stores second information, where the second information is used to indicate a state of the private network AMF element. The second information may be a first identifier or a second identifier, where the second information is the first identifier and is used to indicate that the AMF network element is enabled, and the second information is the second identifier and is used to indicate that the AMF network element is not enabled.
It should be noted that, in the embodiment of the present application, the enabling of the private network AMF means that the access network device (e.g., the base station) can select the private network AMF bearer service, and the disabling of the private network AMF means that the access network device (e.g., the base station) cannot select the private network AMF bearer service.
It should be noted that, the embodiment of the present application does not limit the representation form of the second information. For example, the second information may be represented by a number. For another example, the second information may be represented by letters. For another example, the second information may be represented by a mixture of numbers, letters, etc.
Illustratively, if the second information is the first identifier (e.g., 1), the private network AMF network element is already enabled. If the second information is a second value (e.g., 0), the private network AMF element is not enabled.
Alternatively, the second information may be stored in an AMF Set ID (e.g., AMF Set ID).
In the embodiment of the present application, after the private network AMF network element receives the second message from the disaster recovery AMF network element, the private network AMF may set the second information as the first identifier.
S204, the private network AMF network element sends a third message to the disaster recovery AMF network element.
Wherein the third message is used for indicating that the private network AMF network element is enabled.
In one possible implementation, the second message may further include address information of the disaster tolerant AMF network element. The private network AMF network element may send the third message to the disaster recovery AMF network element according to the address information of the disaster recovery AMF network element.
In one possible design, the third message may be Namf _communication_ Authori zation Response.
Optionally, the third message may include the second information and address information of the network element of the private network AMF.
It should be noted that, the embodiment of the present application does not limit the representation form of the second information. For example, the second information may be represented by a number. For another example, the second information may be represented by letters. For another example, the second information may be represented by a mixture of numbers, letters, etc.
For example, if the second information is a first value (e.g., 0), the state of the private network AMF element is an enabled state. If the second information is a second value (e.g. 1), the state of the private network AMF element is an inactive state.
S205, the disaster recovery AMF network element receives a third message from the private network AMF network element.
S206, the disaster recovery AMF network element sends a first message to the access network device.
Wherein, the first message is used for indicating that the private network AMF network element is enabled, and the first message includes: address information of the private network AMF network element and identification information of the private network AMF network element.
For example, the identification information of the private network AMF network element may be an AMF area ID (such as an AMF Region ID). Or the identification information of the private network AMF network element may include: AMF region ID and AMF Set ID (e.g., AMF Set ID).
In one possible implementation, after the disaster recovery AMF network element receives the third message from the private network AMF network element, the disaster recovery AMF network element may send the first message to the access network device.
That is, after performing S205, the disaster tolerant AMF network element may send a first message to the access network device. Therefore, the disaster recovery AMF network element can be ensured to inform the access network equipment after confirming that the private network AMF network element is started, and the stability is improved.
In another possible implementation, after the disaster recovery AMF network element sends the second message to the private network AMF network element (S203), the disaster recovery AMF network element may send the first message to the access network device before the disaster recovery AMF network element receives the third message from the private network AMF network element.
That is, after performing S203, before S205, the disaster tolerant AMF network element may send a first message to the access network device. Therefore, the time for informing the access network equipment that the special network AMF network element is started can be shortened, and the efficiency of the access network equipment for accessing the special network AMF network element is improved.
S207, the access network equipment receives a first message from the disaster recovery AMF network element.
Wherein the first message is used for indicating that the private network AMF network element is enabled.
In one possible design, the distance between the private network AMF network element and the access network device is smaller than the distance between the disaster tolerant AMF network element and the access network device.
The distance between the network element of the private network AMF and the access network device is 10 km, and the distance between the network element of the disaster recovery AMF and the access network device is 500 km.
It should be noted that, in general, the speed of processing service data by the AMF network element of the private network is faster.
S208, the access network equipment sends the target service data to the AMF network element of the private network according to the first message.
In one possible implementation, the access network device may determine, from the first message, that the private network AMF network element has been enabled. And then, the access network equipment can send the target service data to the private network AMF network element according to the address information of the private network AMF network element.
Based on the scheme, the access network equipment sends a fault message to the disaster recovery AMF network element, wherein the fault message is used for indicating the main core network equipment connected with the access network equipment to generate faults. And then, the access network equipment receives a first message from the disaster recovery AMF network element, wherein the first message is used for indicating that the private network AMF network element is started. And because the distance between the special network AMF network element and the access network equipment is smaller than the distance between the disaster recovery AMF network element and the access network equipment, the time consumed by the access network equipment for sending the service data to the special network AMF network element is smaller than the time consumed by the access network equipment for sending the service data to the disaster recovery AMF network element. Then, the access network device may send the target service data to the private network AMF network element according to the first message. Under the condition that the time spent by the access network equipment for sending the service data to the private network AMF network element is short, the processing time of the service can be reduced, and the time delay of the service is further reduced.
In some embodiments, the access network device stores identification information of a plurality of core network devices to which the access network device may connect. The access network device may select one core network device from the plurality of core network devices, and the service data of the access network device may be processed by the selected core network device.
As shown in fig. 3, a disaster recovery processing method provided in an embodiment of the present application includes:

The configuration information comprises identification information of a plurality of core network devices connected with the access network device, and the updated configuration information comprises identification information of an AMF network element of the private network.
In one possible implementation, after the access network device receives the first message from the disaster tolerant AMF network element, the access network device may add the identification information of the private network AMF network element to the configuration information.
Illustratively, if the configuration information includes: the identification A (such as the identification of the first main AMF network element), the identification B (such as the identification of the second main AMF network element) and the identification C (such as the identification of the disaster tolerant AMF network element) are the identification D of the private network AMF network element. The updated configuration information includes: identifier a, identifier B, identifier C, and identifier D.
In some embodiments, the access network device may determine whether the configuration information includes identification information of a private network AMF network element. If the configuration information does not contain the identification information of the private network AMF network element, the access network equipment updates the configuration information. If the configuration information contains the identification information of the private network AMF network element, the access network equipment does not update the configuration information, i.e. the access network equipment does not add the identification information of the private network AMF network element to the configuration information.
