Abstract
The present disclosure provides a method of processing UE idle state, a mobility management (MM) entity, and a session management (SM) function entity. The method includes: receiving, by the mobility management MM function entity, a connection release request sent by an access network entity, wherein the connection release request carries identifier information of the UE; and sending, by the MM function entity, a user plane connection deactivation request to the SM function entity according to the connection release request, the user plane connection deactivation request is used to request the SM function entity to delete the user plane connection of the UE, and maintain the signaling plane connection of the UE. In this way, after the UE is in an idle state, the user plane between the UE and the core network is not maintained, but the signaling plane remains.
