Abstract: The present disclosure provides a session management method, a mobility management functional entity and a session management functional entity. The session management method includes: judging, by a mobility management functional entity, whether a UE has moved out of an allowed area; when the UE has moved out of the allowed area, determining, by the mobility management functional entity, a management message for a session of the UE; and transmitting, by the mobility management functional entity, the management message to a session management functional entity for serving the UE. The management message is adopted to trigger the session management functional entity to manage the session of the UE.

Abstract: Disclosed are a method and device for managing and controlling a terminal UE. The method is applied to a network data analytics function (NWDAF) entity, and the method comprises: acquiring feature information of a UE; analyzing the feature information, and determining that a security risk exists in the UE; sending a first indication to at least one network function entity in a network, and triggering the at least one network function entity to carry out policy update or parameter adjustment on the UE, wherein the first indication is used for prompting the type of the security risk confronted by the UE, or for indicating a policy or parameter for the security risk of the UE; and/or sending a second indication to the UE, and triggering the UE to raise an alarm and/or carry out risk defense, wherein the second indication is used for prompting the type of the security risk confronted by the UE. The present invention is used for solving the problem of an existing mobile communication network system lacking effective detection and defense on a confronted or potential security risk of a terminal.

Abstract: The present application discloses a method and an apparatus for transmitting downlink data, to resolve the issue of erroneous transmission of downlink data of UE when the UE moves from an EPS network to a 5G network. The method comprises: after receiving a request message for updating a session management context of the UE, a session management function entity in embodiments of the present application determining that the UE has moved from a first network to a second network; the session management function entity notifying a user plane function entity to delete a user plane connection of the UE in the first network, and creating a user plane connection of the UE in the second network, such that the user plane function entity transmits downlink data of the UE through the newly created user plane connection. The embodiments of the present application avoid transmission of the downlink data of the UE through the user plane connection in the first network, so as to ensure accurate transmission of the downlink data of the UE, thereby further improving system performance.
