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.

Abstract: Systems and methods for wireless communications are disclosed herein. In one embodiment, the system and method are configured to receive, by a mobility management function (AMF) from a network function (NF), slice information including at least one of a quality of service (QoS) profile for a slice or a service area of the slice. The AMF can determine that a wireless communication device is authorized to access a slice based on the service area of the slice. The AMF can send the QoS profile comprising a slice-specific aggregate maximum bit rate (AMBR) specific to the slice to the radio access network.

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: A method for processing an authorization change of a Proximity-based Service (ProSe), a first network element device, and a second network element device are described. The method includes that: a ProSe server of a visited network or a local network triggers reauthorization of the ProSe; and the ProSe server of the visited network or the local network sends updated authorization information to a ProSe server of a home network. The updated authorization information includes: an update time limitation indication, and/or time information, and/or an authorization type.

Abstract: Disclosed are a dedicate network selection method and device. Herein, the method includes: a mobility management entity (MME) of a dedicate network acquiring user subscription data of a terminal when receiving a location update request; the MME determining to select a dedicate network for the terminal according to the user subscription data; and the MME judging whether an SGW and a PGW currently being used by the terminal belong to the dedicate network; if the SGW and the PGW currently being used by the terminal do not belong to the dedicate network, then the MME selecting an SGW and/or PGW of the dedicate network for the terminal, and switching the SGW and/or the PGW being used by the terminal to the selected SGW and/or PGW.
