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.

Abstract: A method of updating a PDU session and a network-side device are provided. The method includes: after a User Equipment UE moves across PLMNs or across systems, determining that the UE has a first PDU session of which an anchor SMF is not in a current PLMN; determining a Session Management Function V-SMF in a Visited Public Land Mobile Network VPLMN for the first PDU session, and updating the first PDN session by using the V-SMF.

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: A default quality of service (QoS) control method and device for solving the problem in the prior art that there is no solution for generating a default QoS rule for a NextGen network. In embodiments of the present disclosure, an SMF entity determines a target PCC rule from at least one PCC rule sent by a PCF entity; the SMF entity generates, according to the target PCC rule, a default QoS rule corresponding to a PDU session, and sends the default QoS rule to a UE. According to the embodiments of the present disclosure, because the connectivity and QoS control of the PDU session are ensured, and the target PCC rule used by the SMF to generate the default QoS rule is determined by the PCF entity for a PDU session of the UE, the precise control for a specific UE and a specific PDU session is implemented, and the system performance is further improved.

Abstract: A method of inserting a Session Management Function SMF and an access and mobility management function AMF entity are provided. The method of inserting an SMF includes in a case that a User Equipment UE moves out of a service area of a first SMF entity currently serving a first Packet Data Unit PDU session of the UE, or in a case that selecting a SMF entity for the UE is needed, querying, by using information relevant to the UE, a second SMF entity capable of serving the UE; and updating the first PDU session by using the second SMF entity.
