Background

With the development of Communication technology, users have higher requirements on network stability, and have higher requirements on disaster recovery capability of a core network of a fifth Generation Mobile Communication technology (5 th Generation Mobile Communication technology,5 g).

At present, a 5G core network of an operator may deploy two main Data Centers (DCs) in a region to carry services in the region, where each DC includes network elements such as an Access and Mobility Management Function (AMF), a Session Management Function (SMF), policy Control Functions (PCF), and a Unified Data Management Function (UDM) in the 5G core network. And, the operator can also regard the DC in one other region as disaster recovery DC. Under the condition that both main DCs fail, disaster-tolerant DCs can be selected to process services.

The terms "first" and "second" in the description and claims of the present application are used for distinguishing between different objects and not for describing a particular order of the objects.

Furthermore, the terms "including" and "having," and any variations thereof, as referred to in the description of the present application, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or modules is not limited to only those steps or modules recited, but may alternatively include other steps or modules not recited, or may alternatively include other steps or modules inherent to such process, method, article, or apparatus.

In addition, in the embodiments of the present application, words such as "exemplary" or "for example" are used to mean serving as examples, illustrations or explanations. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "e.g.," is intended to present concepts in a concrete fashion.

Before describing the disaster recovery processing method in the embodiment of the present application in detail, an implementation environment and an application area Jing Jinhang in the embodiment of the present application are described first.

First, an application scenario of the embodiment of the present application is described.

The disaster recovery processing method is applied to a scene where the core network device performs disaster recovery. For the public network user terminal, the implementation of the service is not greatly affected by the remote disaster recovery (i.e. the disaster recovery DC carries the service). In a scenario where two primary DCs in a region fail simultaneously, the disaster recovery DC has the capability of taking over all services in the region. The dual master 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, area a includes provinces a and B, and traffic of area a is carried by a main DC101 and a main DC102, each DC including: SMF Network elements, AMF Network elements, network storage Function (NRF) Network elements, and User Plane Function (UPF) Network elements, etc. When both the main DC101 and the main DC102 have a fault, the base station 103 corresponding to the province a 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. Moreover, the SMF network element of the disaster recovery DC104 may forward the user plane traffic carried by the UPF network element corresponding to the province a according to a Tracking Area Code (TAC), so that the disaster recovery DC104 carries the service of the province a.

However, when the service is processed by using the disaster recovery DC, the disaster recovery DC is a DC deployed in other areas, so that the distance from the disaster recovery DC to the base station is long, the time for transmitting the service data is increased, and the time delay for processing the service by the disaster recovery DC is further increased. Thus, when the two main DCs are failed, normal operation of the service may be affected when the disaster-tolerant DC is used to process the low-latency service.

In order to solve the above problem, an embodiment of the present application provides a disaster recovery processing method. In the method, when the dual-master DC fails, the disaster-tolerant DC may start a private network AMF network element (which may also be referred to as an AMF network element in a lightweight core network), and a distance between the private network AMF network element and the base station is smaller than a distance between the disaster-tolerant DC and the base station. And then, after the base station receives the message that the private network AMF network element is enabled, the base station can 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 short, which can shorten the time for transmitting the service data (or the processing speed of the private network AMF network element is fast). Therefore, the time for processing the 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 embodiments of the present application.

As shown in fig. 1B, a communication system provided for the embodiment of the present application includes a plurality of network devices, where the plurality of network devices may include: base station 105, disaster recovery DC106, private network DC107, base station 105, disaster recovery DC106, private network DC107 may be connected by 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, etc. The method specifically comprises the following steps: the Base Station may be an Access Point (AP) in a Wireless Local Area Network (WLAN), a Base Transceiver Station (BTS) in a Global System for Mobile Communications (GSM) or Code Division Multiple Access (CDMA), a Base Station (NodeB, NB) in a Wideband Code Division Multiple Access (WCDMA), an Evolved Node B (eNB, eNodeB) in LTE, or a relay Station or Access point, or a Base Station in a vehicle-mounted device, a wearable device, and a Next Generation Node B (The Next Generation Node B, gbb) in a future 5G Network, or a Base Station in a future Evolved Public Land Mobile Network (PLMN) Network.

The embodiments of the present application will be described in detail below with reference to the drawings attached to the specification.

As shown in fig. 2, a disaster recovery processing method provided in the embodiment of the present application includes:

s201, the access network equipment sends a fault message to the disaster recovery AMF network element.

The fault message is used for indicating that the main core network equipment connected with the access network equipment has a fault, and the disaster recovery AMF network element is an AMF network element of the disaster recovery DC.

It should be noted that, in this embodiment of the present application, the primary core network device connected to the access network device refers to a core network device that carries a service in the access network device. That is, in the case that the main core network device connected to the access network device does not fail, the main core network device processes the service data transmitted by the access network device.

S202, the disaster recovery AMF network element receives the fault message from the access network equipment.

And S203, the disaster recovery AMF network element sends a second message to the private network AMF network element.

And the second message is used for indicating the private network AMF network element is enabled.

In a possible implementation manner, the disaster recovery AMF network element stores address information of the private network 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 reason for enabling the private network AMF element.

The first information is expressed in a non-limited form in the embodiments of the present application. 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 expressed by mixing numbers, letters, and the like.

For example, if the first information is a first value (e.g. 0), it indicates that the reason for enabling the private network AMF network element is that the main DC is powered off. Or, if the first information is the second value (e.g. 1), it indicates that the reason for enabling the private network AMF network element is that the network failure occurs in both the primary DCs.

Alternatively, the second message may be a Namf _ Communication _ Authorization Request, which may include an establishment Request.

Optionally, the second message may further include authentication information, where the authentication information is used to verify the private network AMF network element.

Correspondingly, the private network AMF network element may receive the second message from the disaster recovery AMF network element.

In some embodiments, the private network AMF network element stores second information, and the second information is used for indicating the state of the private network AMF network 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 this embodiment of the present application, the dedicated network AMF is enabled, which means that an access network device (e.g., a base station) may select a dedicated network AMF bearer service, and the non-enabled dedicated network AMF means that the access network device (e.g., the base station) cannot select the dedicated network AMF bearer service.

The second information is expressed in a non-limited form in the embodiments of the present application. 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 mixedly represented by numbers, letters, and the like.

Illustratively, the private network AMF network element is already enabled, provided that the second information is the first identifier (e.g. 1). 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 this embodiment of the 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 message 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 a possible implementation manner, the second message may further include address information of the disaster recovery 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 a Namf _ Communication _ authorization Response.

Optionally, the third message may include the second information and address information of the private network AMF network element.

Illustratively, if the second information is a first value (e.g. 0), the status of the private network AMF network element is enabled. If the second information is a second value (e.g. 1), the status of the private network AMF element is not enabled.

And 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 equipment.

Wherein, the first message is used for indicating that the private network AMF network element is enabled, and the first message comprises: address information of the private network AMF network element and identification information of the private network AMF network element.

Illustratively, the identification information of the private network AMF network element may be an AMF area ID (e.g., AMF Region ID). Or, the identification information of the private network AMF network element may include: AMF area ID and AMF Set ID (e.g., AMF Set ID).

In a possible implementation manner, 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 recovery AMF network element may send a first message to the access network device. Therefore, the disaster recovery AMF network element can be ensured to notify the access network equipment after the private network AMF network element is confirmed to be started, and the stability is improved.

In another possible implementation manner, after the disaster recovery AMF network element sends the second message to the private network AMF network element (S203), before 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 S203, the disaster-tolerant AMF network element may send a first message to the access network device before S205. Therefore, the time for informing the access network equipment that the private network AMF network element is started can be shortened, and the efficiency of the access network equipment accessing the private network AMF network element is improved.

S207, the access network equipment receives the 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 recovery AMF network element and the access network device.

Illustratively, the distance between the private network AMF network element and the access network equipment is 10 kilometers, and the distance between the disaster recovery AMF network element and the access network equipment is 500 kilometers.

It should be noted that, in general, the speed of processing the service data by the AMF element of the private network is faster.

S208, the access network equipment sends the target service data to the private network AMF network element according to the first message.

In a possible implementation manner, the access network device may determine that the private network AMF network element is enabled according to the first message. 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 that the main core network equipment connected with the access network equipment has a fault. 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 enabled. And because the distance between the private 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 for the access network equipment to send the service data to the private network AMF network element is shorter than the time consumed for the access network equipment to send 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 element according to the first message. Under the condition that the time consumed for the access network equipment to send the service data to the private network AMF network element is short, the service processing time can be shortened, and further the service time delay is reduced.

In some embodiments, the access network device stores therein identification information of a plurality of core network devices to which the access network device may be connected. The access network device may select one core network device from the plurality of core network devices, and the selected core network device processes service data of the access network device.

As shown in fig. 3, a disaster recovery processing method provided in the embodiment of the present application includes:

s301, the access network equipment updates the configuration information according to the address information of the private network AMF network element.

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 a private network AMF network element.

In a possible implementation manner, after the access network device receives the first message from the disaster recovery AMF network element, the access network device may add the identification information of the private network AMF network element to the configuration information.

Illustratively, suppose the configuration information includes: the identifier a (e.g. the identifier of the first primary AMF network element), the identifier B (e.g. the identifier of the second primary AMF network element), and the identifier C (e.g. the identifier of the disaster recovery AMF network element), where the identifier of the private network AMF network element is an identifier D. The updated configuration information includes: identification A, identification B, identification C and identification D.

In some embodiments, the access network device may determine whether the configuration information has identification information of the private network AMF network element. And if the identification information of the private network AMF network element does not exist in the configuration information, 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, namely the access network equipment does not add the identification information of the private network AMF network element to the configuration information.

Optionally, the configuration information may further include address information of a plurality of core network devices connected to the access network device. The access network equipment may add address information of the private network AMF network elements to the configuration information.

In some embodiments, after updating the configuration information, the access network device may determine, according to the updated configuration information, that a connection is established between the access network device and the private network AMF network element. And then the access network equipment can send the target service data to the private network AMF network element.

It can be understood that, updating the private network AMF element to the configuration information may enable the access network device to determine that the private network AMF is already connected, and may use the private network AMF element to process the service, so as to reduce the service delay.

In some embodiments, the private network AMF element is configured to process target service data, where the target service data is service data of a private network user terminal. That is to say, the AMF network element of the private network can only process the service data of the user terminal of the private network, but cannot process the service data of other user terminals.

As shown in fig. 4, a disaster recovery processing method provided in the embodiment of the present application includes:

s401, the private network AMF network element sends a fourth message to the private network UDM network element.

And the fourth message is used for indicating to send the subscription data of the private network user terminal to the access network equipment.

In some embodiments, after the private network AMF network element receives the second message from the disaster recovery AMF network element, the private network AMF network element sends a fourth message to the private network UDM network element.

In other embodiments, after the disaster recovery AMF receives the third message from the private network AMF network element, the disaster recovery AMF may send a sixth message to the private network UDM, where the sixth message is used to indicate that the subscription data of the private network user terminal is requested. And then, the private network AMF network element receives the sixth message and sends a fourth message to the private network UDM network element.

Correspondingly, the private network UDM network element may receive the fourth message from the disaster recovery AMF network element.

S402, the private network UDM network element sends the subscription data of the private network user terminal to the access network equipment.

In one possible implementation, the fourth message may include identification information of the private network. The private network UDM may determine subscription data of the private network user terminal according to the identification information of the private network. And then, the private network UDM network element sends the subscription data of the private network user terminal to the access network equipment.

In some embodiments, the private network UDM network element may update subscription data for the private network user terminal. The private network UDM element may send a synchronization request message to the master UDM element, where the synchronization request message is used to request for synchronizing subscription data of the private network user terminal. And then, the main UDM network element can send the subscription data of the private network user terminal to the private network UDM network element.

S403, the access network equipment receives the subscription data of the private network user terminal.

In one possible implementation, the access network device may receive subscription data from a private network user terminal of a private network UDM network element.

S404, the access network equipment receives the service request message.

Wherein, the service request message includes: service data of a plurality of user terminals and subscription data of a plurality of user terminals.

It should be noted that, in the embodiment of the present application, the order in which the access network device receives the service request message (i.e., S404) is not limited. For example, S404 may precede S401. For another example, S404 may precede S201. For another example, S404 may precede S301.

S405, the access network equipment determines target service data from the service data of the plurality of user terminals according to the subscription data of the plurality of user terminals and the subscription data of the private network user terminals.

The target service data is service data corresponding to the user terminal with the same subscription data as the private network user terminal.

In one possible implementation, the access network device may compare the subscription data of the plurality of user terminals with the subscription data of the private network user terminal. And then, the service data corresponding to the user terminal with the same subscription data as the private network user terminal in the plurality of user terminals is taken as the target service data.

Illustratively, the plurality of user terminals includes: the terminal A, the terminal B and the terminal C, the signing data of the terminal A is signing data A, the signing data of the terminal B is signing data B, and the signing data of the terminal C is signing data C. The subscription data of the private network user terminal comprises subscription data A and subscription data C, the terminal A and the terminal C are private network user terminals, and the service data of the terminal A and the service data of the terminal C are target service data.

It can be understood that the access network device obtains the subscription data of the private network user terminal, and can determine the target service data.
