[0067] In the embodiment of the present invention, the operator can use the user information obtained by its operation support system, terminal information, service information provided by the service network or third-party applications, and the communication model of the user to mine the information of the user terminal in its network. Mobility models (or laws), characteristics of mobile applications. Then, based on the obtained above information, it can determine the level of mobility support that needs to be provided in the network, such as high, medium or low level of mobility support.

[0068] Correspondingly, the operator's network management system divides its network according to the required mobility support level, such as performing network slicing, so that different networks can implement 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, the...

[0111] Such as Figure 3A and 3B As shown, the mobility level determination function is implemented in each network. For specific implementation, 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 according to the mobile information and services of the terminal 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 terminal type, subscription, and the like.

[0113] see Figure 4 , combined with Figure 4 Introduce the procedure for a te...

[0120] see Figure 5 , which shows that the network selection function selects a 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 a terminal accesses a network, requests location update or establishes a connection, the network selection function selects an appropriate target network according to the current mobility level required by the terminal. Of course, it can be understood 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 terminal attaches to the network similar to the prior art, and the network selection function selects a target network according to the terminal type, subscription, and the like.

[0122] see Figure 6 , to introduce the process of the terminal initiating connection establishment or location...

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...
