Embodiment 1

[0052] In order to perform mobility management, the capability opening functional entity needs to manage the location of the terminal, so this embodiment provides a method for managing the location of the terminal, as Figure 6 shown, including:

[0053] Step 110, the CEF sends a location subscription request for the terminal to the network slice that provides services for the terminal;

[0054] In this embodiment, the CEF sends a location subscription request to the network slice that provides services for the terminal, including: the CEF receives a mobility management message for the terminal sent by a third-party application server APP, and obtains an identifier of the terminal ; The CEF queries the network slice management function entity NSMF to obtain information about the network slice that provides services for the terminal according to the identifier of the terminal; and, the CEF sends the location subscription to the network slice that provides services for the termi...

Embodiment 2

[0074] This embodiment provides a method for terminal mobility management, such as Figure 8 shown, including:

[0075] Step 210, the CEF determines to initiate a mobility management service to the terminal;

[0076] This step can specifically include CEF decision-making or third-party APP decision-making methods:

[0077] CEF decision-making: the CEF obtains the location information of the terminal and the information of the network slice currently providing services for the terminal, and decides to initiate a mobility management service to the terminal based on a local mobility management strategy;

[0078] Third-party APP decision-making: the CEF obtains the location information of the terminal and the information of the network slice that currently provides services for the terminal, and reports it to the third-party APP. After receiving the third-party APP, it makes a decision on the The terminal initiates a notification message of the mobility management service.

example 1

[0127] In this example, the capability opening function entity subscribes terminal location information to the network slice serving the terminal according to the third-party mobility management requirements. The third-party APP can also subscribe to the location information of the terminal through the capability opening function entity to provide location-related services, such as deciding whether to initiate mobility management services. The capability exposure functional entity queries the network slice management functional entity for network slice information that provides services for the terminal, and subscribes to the queried network slice for location update information of the terminal. When the location of the terminal is updated in the network area, the network slice currently serving the terminal reports the location information of the terminal in time.

[0128] Figure 10 Shown is the signaling flow of this example, including:

[0129] Step S301, providing third...

Abstract

A method for terminal location management and terminal mobility management, and a network node. When performing location management, a capability opening function entity CEF sends a location subscription request for the terminal to a network slice that provides services for the terminal; the CEF receives the current The terminal provides the report of the network slice of the service, and obtains the location information of the terminal. When performing the mobility management method, the CEF selects or creates a target network slice for the terminal through the network slice management function entity NSMF; the CEF notifies the terminal to switch to the target network through the network slice currently serving the terminal slice. Through the above solution, when the terminal moves to a different area, the location of the terminal can be obtained, and a specific network slice that meets its service requirements can be selected or created for the terminal in the area to provide services for the terminal.

Description

technical field [0001] The present invention relates to network communication, and more specifically, to a method for terminal location management and terminal mobility management and a network node. Background technique [0002] In the past 20 years, mobile communication technology has developed rapidly, which has brought huge impact on people's life style, work style, and social politics and economy. Human society has entered an efficient information age, and the demand for various business applications has shown explosive growth, which has brought huge challenges to the future wireless mobile broadband system in terms of frequency, technology, and operation. [0003] With the enrichment of various Internet applications, third-party service providers have increasingly strong demands on network operators for information interaction and network personality, and network capability opening has gradually become the mainstream of future network technologies. For example, some o...
