The embodiment of the application provides a terminal registration method and device based on a distributed network, which are used for solving the problem that the existing centralized network registration method is not suitable for the distributed network.

The method and the device are based on the same application, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.

As shown in fig. 1, an embodiment of the present application provides a terminal registration method based on a distributed network, which is applied to a first access mobility management function, and specifically includes the following steps:

Step 101, under the condition that a first access mobility management function receives a registration request message sent by a terminal, determining that an access mobility management function belonging to a second network node needs to be selected to provide service for the terminal according to first related information of a first network node to which the first access mobility management function belongs; wherein the first network node and the second network node are different distributed network nodes.

In this embodiment, the first access mobility management function is an access mobility management function to which the terminal is initially accessed. The first access mobility management function is attributed to a first network node, which may be a network node to which the terminal currently belongs. When a terminal accesses to a network, a first network node configures an initial access mobility management function (namely the first access mobility management function) for the terminal, and the terminal sends a registration request message to the initial access mobility management function.

The initial access mobility management function may determine whether the terminal can be served (e.g., whether the terminal can be served according to its own load) by receiving the registration request message, and if not, determine that the access mobility management function reselection is required.

When the access mobility management function is reselected, the first access mobility management function may select other access mobility management functions belonging to the same network node (i.e., the first network node), or may select other access mobility management functions belonging to different network nodes (e.g., the second network node).

The first access mobility management function may determine, according to first related information of the first network node, that an access mobility management function belonging to the second network node needs to be selected to provide a service for the terminal. For example: aiming at the sudden increase of the number of users in certain time periods, the current network node can only serve part of the number of users, such as sports events, large performances and other activity scenes, the same network node can not provide services for the terminal, other network nodes are required to cooperate to serve the users so as to save network deployment cost, and the current network resources can be fully utilized.

step 103, the first access mobility management function determines a second access mobility management function according to the second related information;

104, the first access mobility management function sends the registration request message to the second access mobility management function;

In this embodiment, when it is determined that the second network node needs to be selected to cooperate to provide services for the user, the first access mobility management function may acquire relevant information of one or more other network nodes, so that the second network node that needs to be accessed may be selected, and select the second access mobility management function that needs to be accessed according to the relevant information of the second network node. The first access mobility management function may send the registration request message to the second access mobility management function, thereby completing terminal registration.

The first access mobility management function may send the registration request message to the second access mobility management function, either directly or indirectly (via forwarding by another functional node).

It should be noted that, in the embodiment of the present application, the network node is also referred to as a distributed network node, and may represent a core network that is customized on demand or has a complete function.

Load information;

The other network node may be a neighbor network node or a centralized network node of the first network node. For example: the initial access mobility management function selects an appropriate access mobility management function of the neighbor network node based on the acquired second related information of the neighbor network node to complete the registration process of the UE. And the initial access mobility management function determines whether to directly forward the UE registration request to the target access mobility management function based on the service range, location, etc. of the candidate access mobility management function of the alternative neighbor network node.

Wherein the first functional node is a network function storage function or a data function storage function attributed to the first network node.

In this embodiment, the first access mobility management function may request second related information of a second network node from the first function node, where the first function node finds or searches other function nodes for the second related information based on the request message itself, and feeds back to the first access mobility management function. The first functional node may be a network function storage function or a data function storage function attributed to the first network node. The implementation process of the first access mobility management function to obtain the related information of the second network node through the first functional node is illustrated below.

Optionally, when a suitable target Network node is selected for the UE, the initial Access mobility management function determines that the UE is in a service range of the first Access mobility management function based on the current UE location, and sends a registration request of the UE to AN Access Network (AN). The access network sending the registration request of the UE to the second access mobility management function may include: the access network sends the registration request message to the second access mobility management function, or the access network sends the registration request message of the UE to the initial network opening function, which sends the registration request message to the second access mobility management function.

Optionally, in the process that the second access mobility management function completes registration, subscription data may be registered and acquired with a unified data management function, and access and mobility policies may need to be acquired with a policy control function, where the acquisition manner may include the following several ways:

(1) If the registration request message received by the second access mobility management function carries initial unified data management function/policy control function information, the second access mobility management function directly interacts with the initial unified data management function/policy control function to complete registration and acquisition of the UE subscription data/policy based on the initial unified data management function information/policy control function information.

(2) If the registration request message received by the second access mobility management function does not carry the initial unified data management function/policy control function information, the target access mobility management function acquires the subscription data/policy and registration of the UE from the local unified data management function/policy control function based on the local configuration policy.

(3) If the registration request message received by the target access mobility management function does not carry the initial unified data management function/policy control function information, the target access mobility management function acquires the subscription data/policy and registration of the UE from the initial unified data management function/policy control function through the initial access mobility management function.

(4) If the registration request message received by the second access mobility management function carries initial network opening function information, the second access mobility management function directly interacts with the initial network opening function to complete registration and acquisition of the UE subscription data/strategy.

The terminal registration procedure of the present application is illustrated below.

Taking the example that the functional node belonging to the first network node is called an initial node and the functional node belonging to the second network node is called a target node, for example: the first access mobility management function is referred to as an initial access mobility management function, and the second access mobility management function is referred to as a target access mobility management function.

As shown in fig. 8, the terminal registration process includes:

Step 1-step 2, the terminal sends a registration request to the access network AN, and the access network sends the registration request to the initial access mobility management function.

And step 3, since the service capability (including load, number of service UEs and the like) of the access mobility management function and other access mobility management functions in the network node are overloaded, the initial access mobility management function determines to select the access mobility management function of other network nodes to cooperate as the UE service. The target access mobility management function of the proper neighbor network node is selected by acquiring the load of the access mobility management function of the neighbor network node or the centralized node, the number of service UEs, DNN (list), position information, service (list), service range and other information. The method for obtaining the service capability and service scope of the target access mobility management function of the neighbor network node or the centralized node is not described herein.

Step 4, executing in two cases:

(A) The initial access mobility management function determines that the UE is not in the service range of the target access mobility management function based on the current UE location, and then determines to send a registration request message of the UE to the target access mobility management function, where the registration request message carries at least initial unified data management function/policy control function information, such as address information, URL information, and the like. Optionally, the initial access mobility management function retains at least the following information: UE identity, information of access mobility management function of service (including information of network node identity, address information, URL, etc.), and information of UE status, etc.

(B) The initial access mobility management function determines that the UE is in a service range of the target access mobility management function based on the current UE location, and then sends a registration request message of the UE to the RAN, where the registration request message carries at least information of the initial unified data management function/policy control function, such as address information, URL, and the like. The RAN sends a registration request of the UE to the target access mobility management function.

Step 5 (including step 5 a-step 5 c), the target access mobility management function sends a registration request message, a UE subscription data acquisition request, subscription data subscription and other request messages to the initial unified data management function based on the information sent by the initial unified data management function, so as to complete registration, subscription data acquisition and subscription.

And 6, the target access mobility management function directly interacts with the initial policy control function to complete the establishment/modification of the UE policy association based on the policy control function information, such as address information, URL and the like.

Step 7, if the condition (A) is executed in the step 4, executing the step (A), namely, the target access mobility management function feeds back a registration acceptance response message to the terminal through the initial access mobility management function and the RAN; if the step 4 is performed in the case of (B), the step is performed in the case of (B), that is, the target access mobility management function directly feeds back the registration acceptance response message to the terminal.

Or as shown in fig. 9, the terminal registration process includes:

Step 4, executing in two cases:

(A) The initial access mobility management function determines that the UE is not in the service range of the target access mobility management function based on the current UE location, and then determines to send a registration request message of the UE to the target access mobility management function, where the registration request message carries at least relevant information of the UE itself, such as address information, URL information, and the like. Optionally, the initial access mobility management function saves at least the following information: UE identity, information of access mobility management function of service (including information of network node identity, address information, URL, etc.), and information of UE status, etc.

(B) The initial access mobility management function judges that the UE is in the service range of the target access mobility management function based on the current UE position, and sends a registration request message of the UE to the RAN, wherein the registration request message at least carries relevant information of the initial access mobility management function, such as address information, URL and the like. The RAN sends a registration request down message of the UE to the target access mobility management function.

Step 5 (comprising steps 5 a-5 c), the initial access mobility management function sends a registration request message to the initial unified data management function. The target access mobility management function sends a request message such as a UE subscription data acquisition request and subscription of subscription data to the initial unified data management function information through the initial access mobility management function so as to complete registration, subscription data acquisition and subscription.

And 6, the target access mobility management function interactively completes the establishment/modification of the UE policy association to the initial policy control function through the initial access mobility management function.

Or as shown in fig. 10, the terminal registration process includes:

Step 4, executing in two cases:

And if the initial access mobility management function judges that the current UE position is not in the service range of the target access mobility management function, determining to send a registration request message of the UE to the target access mobility management function. Optionally, the initial access mobility management function retains at least one of the following information: UE identity, information of access mobility management function of service (including information of network node identity, address information, URL, etc.), and information of UE status, etc.

(B) The initial access mobility management function judges that the UE is in the service range of the target access mobility management function based on the current UE position, and sends a registration request message of the UE to the RAN, wherein the registration request message at least carries relevant information of the initial access mobility management function, such as address information, URL and the like. The RAN sends a registration request message of the UE to the target access mobility management function.

Step 5 (including step 5 a-step 5 c) and step 6, since the target access mobility management function does not have the initial access mobility management function, the initial unified data management function and the initial policy control function related information, the target access mobility management function performs information interaction with the initial unified data management function and the initial policy control function in the present network node to complete registration, subscription data acquisition and subscription, and complete UE policy association establishment/modification. Here, the interaction process between the unified data management function and the policy control function in the target network node and the initial unified data management function and the initial policy control function is not described in detail.

Step 7, if the case (A) is executed in the step 4, executing the step (A); if the case (B) is performed in step 4, this step is performed (B).

Or as shown in fig. 11, the terminal registration process includes:

Step 4 (including step 4a and step 4 b), the initial access mobility management function determines that the UE is in the service range of the target access mobility management function based on the current UE location, and then sends a registration request message of the UE to the RAN, and carries information of the initial network function opening function and information of the target access mobility management function, such as address information, URL information, service operation, and the like. The RAN sends the registration request message to the initial network function opening function based on the network function opening function information carried in the registration request message. The initial network function opening information sends the registration request to the target access mobility management function and carries information of the initial network function opening information, such as address information, URL information, service operation and the like.

Step 5 (including step 5 a-step 5 c) and step 6, since the target access mobility management function does not have the initial unified data management function and the initial policy control function related information, the target access mobility management function requests, signs up for data acquisition and signs up for based on the initial network function development function information to the initial network function open function, respectively. And meanwhile, the UE policy association establishment/modification is completed through interaction of the initial network function opening function and the initial policy control function.

And 7, the target access mobility management function sends a registration acceptance message to the UE. In this process, the initial network function opening function generates UE context information including at least UE ID, serving target access mobility management function information.

Or as shown in fig. 12, the terminal registration process includes:

Step 4 (including step 4a and step 4 b), the initial access mobility management function determines that the UE is in the service range of the target access mobility management function based on the current UE location, and then sends a registration request message of the UE to the RAN, and carries information of the initial network function opening function and information of the target access mobility management function, such as address information, URL information, service operation, and the like. The RAN sends the registration request message to the network function opening function based on the network function opening function information carried in the registration request message. The initial network function open information sends a registration request to the target access mobility management function.

Step 5 (including step 5 a-step 5 c) and step 6, since the target access mobility management function does not have the initial unified data management function, the initial policy control function and the initial network function opening function related information, the target access mobility management function interacts with the target unified data management function and the target policy control function in the present network node to complete registration, subscription data acquisition and subscription, and UE policy association establishment/modification.
