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: Methods and devices for notifying an authorization update are provided. In a method for notifying an authorization update, a home network Proximity-based Services (ProSe) functional entity of an announcing terminal receives a notification message from a ProSe application server, where the notification message is used for notifying the home network ProSe functional entity of the announcing terminal that authorization information changes (S302); and the home network ProSe functional entity of the announcing terminal notifies a home network ProSe functional entity of a monitoring terminal that a ProSe code and/or filter corresponding to the announcing terminal become/becomes invalid or are/is updated (S304).

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 system and method of registration with AMF re-allocation. The system and method includes receiving, by an initial AMF from a wireless communication device via a RAN, a registration request comprising a first device identifier associated with the wireless communication device. The system and method includes determining, by the initial AMF, an identifier type associated with the first device identifier. The system and method includes generating, by the initial AMF, a reroute message comprising a second device identifier. The system and method includes originating, by the initial AMF to the wireless communication device, a security mode command message comprising a redirection criteria or an integrity negotiation algorithm, the security mode command message causes the wireless communication device to set the redirection criteria allowing the wireless communication device to accept a request message that is not integrity protected and return a security mode complete message to the initial AMF.
