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: Methods, apparatuses, and systems for providing management of network slices are disclosed. In one aspect, a wireless communication method is disclosed. The method includes receiving, by a network side function operating in a wireless network in which network services are provided as one or more network slices, a request for a quota information associated with a network slice selection assistance information. The process further includes transmitting, by the network side function, in response to the request, the quota information for the network slice information.

Abstract: A method for changing a user plane function for a user equipment in a wireless network involves a computing device such as a session management function carrying out the following actions: when the user equipment is activating a protocol data unit session and has moved out of a service area of a first user plane function, establishing a tunnel for downlink data for the user equipment between the first user plane function and a second user plane function, but not between an anchor user plane function and the second user plane function; once the protocol data unit is deactivated, tearing down the tunnel between the first user plane function and the second user plane function and establishing a tunnel between the anchor user plane function and the second user plane function for downlink data.

Abstract: Disclosed are methods, systems and devices for single radio voice call continuity (SRVCC) in 5G networks. One method of maintaining voice call and Internet Protocol (IP) continuity includes transmitting, upon determining that a voice service in a first network has terminated, a request to join a second network, where the request includes an identifier associated with the second network that is mapped from an identifier associated with a third network, and where the mapping indicates that the wireless device is joining the second network from the third network, and performing a communication operation in the second network using IP information that was used to perform the voice service in the first network. In another method, the request includes a mobility registration type.

Abstract: A method for facilitating handover in a wireless network involves (e.g., a user equipment) receiving a globally unique temporary identifier from an access and mobility management function that serves the second radio access network, registering with the access and mobility management function via a third radio access network (which may be an untrusted network) that has a radio access technology that is different from that of the first radio access network and the second radio access network, and transmitting an attach request message or a tracking area update containing the globally unique temporary identifier to a mobility management entity that serves the first radio access network.
