Example

[0066] First embodiment

[0067] In the embodiment of the present invention, the operator can use the user information, terminal information, service network or third-party application provided by the service information, the user's communication model, etc., obtained by its operation support system, to dig out the user terminal information in its network. Mobility model (or law), the characteristics of mobile applications. Then, based on the obtained information, the level of mobility support that needs to be provided in the network can be determined, such as high, medium, or low level of mobility support.

[0068] Correspondingly, the network management system of the operator divides its network according to the required mobility support level, such as network slicing, so that different networks can achieve different levels of mobility support. However, multiple levels of mobility support may be implemented in a network.

[0069] When the terminal accesses the operator’s network,...

Example

[0110] The third embodiment

[0111] Such as Figure 3A with 3B As shown, each network has implemented the mobility level determination function. When it is implemented, the mobility level determination function is located in the corresponding network, see Figure 3A ; The mobility level determination function may be shared by multiple networks, see Figure 3B . The purpose is to determine the mobility support level required by the current terminal based on the terminal's mobile information and services after the terminal accesses the network, so as to select a network that can provide a suitable mobility management mechanism or function for the terminal.

[0112] It should be noted that the process of attaching the terminal to the network in this embodiment is similar to the prior art, and the network selection function selects the target network according to the type of the terminal and the contract.

[0113] See Figure 4 , Combined Figure 4 Introduce the process for the terminal...

Example

[0119] Fourth embodiment

[0120] See Figure 5 , The figure shows that the network selection function selects the target network according to the mobility support level required by the terminal. Such as Figure 5 As shown, the mobility level determination function is independent of each network. When the terminal accesses the network, requests location update or establishes a connection, the network selection function selects a suitable target network according to the mobility level currently required by the terminal. Of course, it is understandable that the mobility level determination function and the network selection function may be set as a functional entity.

[0121] It should be noted that in this embodiment, the attachment of the terminal to the network is similar to the prior art, and the network selection function selects the target network according to the type of the terminal and the contract.

[0122] See Image 6 , Introduce the process of the terminal initiates conne...

Abstract

The embodiment of the invention provides a method and device for selecting a mobility management mechanism for a terminal as required.The method includes the steps that the mobility support level required by the terminal is determined; the network selection function is informed to select a network or a network function capable of supporting the required mobility support level according to the determined mobility supporting level required by the terminal, so that corresponding mobility management is provided for the terminal.Different networks offer services to terminals of different mobility supporting requirements, complex network function configuration is avoided, and complexity of mobility management is effectively lowered.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for selecting a mobility management mechanism for a terminal on demand. Background technique [0002] According to the description of 3GPP TR22.891, the future 5G network needs to provide mobility support for different requirements. Because there are different communication scenarios in the 5G network: different terminals have different mobile paradigms, for example, some terminals access the network while moving at high speed, while others access the network nomadicly or statically; different business It also has different mobility support requirements. For example, some services want to reduce the interruption and packet loss rate during service transmission, so the network is required to shield the mobility events from the application layer, including keeping the IP address unchanged during the handover process, while other Some applications...
