摘要
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.
