    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.

    IPC: H04W12/069

    Abstract: The present disclosure describes methods, systems and devices for establishing secure communication between a user equipment and a service application in a wireless communication. One method includes receiving, by the user equipment, an authentication and key management for service applications identifier (AKMAID) from an authentication server function (AUSF) upon successful completion of an authentication process for registering the user equipment with the communication network. The method also includes storing, by the user equipment, the AKMAID; deriving, by the user equipment, an application key based on a base authentication key; sending, by the user equipment, a communication request to the service application, the communication request comprising the AKMAID; and receiving, by the user equipment, an application session establishment response to the communication request from the service application to establish a security communication session between the user equipment and the service application based on the application key.

    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).
