Device-side, translator functions may be authenticated by elements of a 5G core network before communications involving such functions are allowed to occur, or continue to occur.

Concepts and technologies disclosed herein are directed to an enhanced software-defined networking (“SDN”) controller to support ad-hoc radio access technologies (“RATs”). An SDN controller receives, from an ad-hoc radio access controller serving an ad-hoc radio access network (“RAN”), an attach request sent on behalf of a user equipment (“UE”) operating in communication with an ad-hoc RAT transceiver node. The attach request includes a physical IP address associated with the UE. The physical IP address includes an IP address sub-interface pre-fix broadcast to the UE by the ad-hoc RAT transceiver node combined with a physical address of the UE. In response to the attach request, the SDN controller can complete an attachment procedure for allowing the ad-hoc radio access controller to an SDN network. The SDN controller also can update one or more components operating within the SDN network to reflect how to reach the UE via the physical IP address.

A method of managing mobility of a mobile terminal in a communication network comprising a plurality of access points and an access points discovery server adapted for providing the mobile terminal with a list of the network access points to which the mobile terminal can connect is disclosed. In some embodiments, the method comprises recovery, by the access points discovery server, of a velocity vector of the mobile terminal, and generation, by the access points discovery server, of the list of access points as a function of said velocity vector.

The present invention provides a method for determining a core network type during a handover process, a terminal device, an access network device, and a core network device. In a process of cell handover, a target access network device may determine the core network type of a target cell according to preferred core network type information reported by a terminal device; alternatively, the target access device may determine the core network type of the target cell by information exchange with a core network device. Therefore, smooth cell handover is ensured, and user experience is improved. The method comprises: during a process of handover of a terminal device from a source cell to a target cell, the terminal device sends preferred core network type information for the target cell to a source access network device, wherein the preferred core network type information is reference information for determining the core network type of the target cell.

Disclosed are a method for selecting an access network in a wireless communications system and an apparatus therefor. In a wireless communications system, a method for a terminal to select an access network according to an embodiment of the present invention includes the steps of: receiving the policy information of a first network; receiving the policy information of a second network; determining the load value of a WLAN (Wireless Local Area Network) access network; and comparing the load value with a predetermined reference value so as to determine whether the WLAN access network is overloaded. The predetermined value can be determined by comparing first reference information for determination of the WLAN access network overload contained in the policy information of the first network with second reference information for determination of the WLAN access network overload contained in the policy information of the second network.
