Embodiment 1

[0117] Embodiment 1, mobility management level in subscription information

[0118] Define the mobility support level or mobility management mechanism signed in the future 5G network, such as Level I, Level II, Level III; Centralized MM, Distributed MM...

[0119] When an operator signs a contract with a user, it determines the mobility support level of the terminal user's initial subscription based on the terminal type, subscription service, etc., and writes the subscription information, for example, for voice / video For business smart phones (smart phones), write a higher mobility support level, and for machine communication terminals that sign up for small data transmission, write a lower mobility support level. As shown in Table 4-1 below:

[0120] Table 4-1 Mobility support level or mobility management mechanism for initial subscription

[0121]

[0122]

[0123] The English abbreviations in the table have the following meanings:

[0124] PLMN: Public Land Mobile ...

Embodiment 2

[0135] When the terminal accesses, determine the current mobility management level or mobility management mechanism of the terminal.

[0136] When a terminal accesses the network, the mobility support level determination function in the network needs to determine the current mobility support level or mobility management mechanism provided to the terminal. During this process, the network needs to obtain the description of the service requested by the terminal, the location of the terminal , and the contract information of the terminal.

[0137] image 3 A flow diagram for determining the current mobility support level of the terminal, as shown in the figure, may include:

[0138] Step 301, receiving a terminal access request, and obtaining the current TAI (Tracking Area ID, tracking area identification) and Application ID (application identification);

[0139] Step 302, searching for user subscription information, and determining the current mobility support level or mobilit...

Embodiment 3

[0146] When an accessed terminal requests a new service, determine the current mobility management level and / or mobility management mechanism of the terminal.

[0147] If the terminal currently only performs control plane registration and does not obtain any services, the mobility support level determination function in the network obtains the service description requested by the terminal and / or the terminal location search for the subscribed mobility support level or mobility in the terminal subscription information Management mechanism, find the corresponding mobility support level or mobility management mechanism, and determine the specific mobility management mechanism. Then for the terminal, only the mobility management mechanism service is used.

[0148] If the terminal has currently obtained the service, the mobility support level determination function in the network obtains the service description and / or terminal location requested by the terminal, searches for the si...

Abstract

The invention discloses a method and a device for determining and providing the mobility management support and treatment required by a terminal. The method comprises the steps of determining the mobility management mapping relationship of a terminal according to the information related to the terminal and the mobility management, wherein the mobility management mapping relationship refers to the condition of the terminal and the mobility management required by the terminal; according to the mobility management mapping relationship, determining the mobility management level or mechanism to be provided to the terminal and sending out an indication. According to the invention, the network-side equipment receives the indication of the mobility management level or mechanism provided to the terminal, and provides the mobility management to the terminal according to the indication. By adapting the scheme provided by the embodiment of the invention, the on-demand mobility management can be realized.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and a device for determining and providing mobility management support and processing required by a terminal. Background technique [0002] On-demand mobility support refers to: According to the description of 3GPP TR 22.891, 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 add...
