Abstract: The embodiments of the present disclosure provide a method and an apparatus for connection handling. The method includes: receiving a connection request that requests for establishing or resuming a connection with a base station; and instructing a Non-Access Stratum (NAS) of a terminal to perform a predetermined operation based on an obtained first connection result corresponding to the connection request. In this way, the problems associated with inconsistent operations in the user plane optimization in the related art can be solved and the consistency in operations between the Access Stratum (AS) and NAS of the terminal can be achieved.

Abstract: A method for gateway recovery processing and device, the method comprising: in the case where a terminal moves from a first mobility management unit to a second mobility management unit, the second mobility management unit receiving flag information from the first mobility management unit, wherein the flag information being used to indicate that a connection signaling of a packet data network (PDN) is in a suspension state; and the second mobility management unit transmitting the flag information to a serving gateway (SGW), the flag information being used to trigger the SGW to send a bearing update request message to a PGW as a packet data network element. The above technical solution achieves that the PGW is notified when a UE moves to a new mobility management unit, so as to ensure the terminal to receive downlink service.

Abstract: An access and mobility management function (AMF) is modified with network slice information. First requested network slice information of a protocol data unit session is received from a wireless terminal. Second requested network slice information is generated based on the first requested network slice information of the PDU session and supported network slice information of a radio access network node of the wireless terminal
