Abstract: Disclosed are a method and device for processing non-matching between a UE unit and a network state applicable to an access and mobility management (AMF) function. The method comprises: upon receiving a non-access stratum message transmitted by a UE unit or an N2 interface message transmitted by a radio access network (RAN) node, determining that the UE unit is in a connected state at a network side; and if it is determined that a change occurs in a RAN node serving the UE unit, notifying said RAN node that a context of the UE unit and an existing user plane connection are to be released. The invention solves technical problems in the prior art of inefficient use of an air interface resource and packet loss, thereby reducing paging overheads and packet loss.

Abstract: Disclosed are a network configuration method and a network device for dynamically selecting a mobility state machine and a tunnel type matching a terminal and increasing resource utilization efficiency. The method comprises: when a terminal accesses a network, determining an attribute of the terminal; determining, on the basis of the attribute of the terminal, a configuration parameter corresponding to the terminal; and directing or configuring, on the basis of the configuration parameter, the terminal and/or directing or configuring a related network function entity or node at a network side.

Abstract: Disclosed are a method and apparatus for determining and providing mobility management support and processing required by a terminal. The method comprises: determining a mobility management mapping relation and a mobility mapping relation of a terminal according to information of the terminal related to mobility management or mobility, the mobility management mapping relation being a mapping relation between conditions for the terminal and a required mobility support level or mobility management mechanism, and the mobility mapping relation being a mapping relation between the conditions for the terminal and mobility levels of the terminal; and determining, according to the mobility management mapping relation of the terminal or according to the conditions for the terminal and the mobility mapping relation of the terminal, a mobility support level or a mobility management mechanism provided for the terminal. A network side device receives an instruction for providing a mobility support level or a mobility management mechanism for the terminal, and provides mobility management for the terminal according to the instruction. By using the solution provided in embodiments of the present application, on-demand mobility management can be implemented.
