Abstract: Methods and systems for managing AMF re-allocation is provided. The method for managing AMF reallocation during UE registration procedure with a 5G network comprises: determining if the first AMF may send a routing assistance information to the UE, on the first AMF determining that the first AMF is not a right AMF to serve the UE; sending a routing assistance information, to the UE, as response to a first registration request message; receiving routing assistance information from the first AMF; sending a second registration request message to a 5G RAN of the 5G network comprising a portion of content included in the routing assistance information; and routing the second registration request message to a second AMF of the 5G network, wherein the second AMF is determined by the 5G RAN based on the portion of content included in the routing assistance information.

Abstract: A method performed by a user equipment (UE) in a wireless communication system comprises: identifying whether the UE supports and intends to use at least one multi-universal subscriber identity module (USIM) feature; transmitting, to an access and mobility management function (AMF) entity, a registration request message including information of multi-USIM features supported by the UE, in a case that the at least one multi-USIM feature being supported and intended to use by the UE is identified; receiving, from a base station (BS), a registration accept message including an indication of multi-USIM features for the UE based on the registration request message, and wherein the indication of multi-USIM features for the UE is identified by the AMF based on network information and the information of multi-USIM features; and identifying at least one multi-USIM feature indicated as supported for the UE by the AMF based on the registration accept message.

Abstract: Provided is a method and apparatus for enhancing the reliability in a wireless communication system. An operating method of a user plane function (UPF) in a wireless communication system includes: receiving network function (NF) set related information changed through an association procedure with respect to an NF; changing a profile of the NF, based on the received NF set related information; and performing an operation related to the NF, based on the changed profile.
