Abstract: A method for communication by a UE in a wireless communication system is provided. The method may comprise sending a first request message to access a data service over a first NSSAI and a voice service over a second NSSAI to a first 3GPP RAT of a first PLMN; receiving a first response message indicating a rejection for establishing an internet PDU session with the first 3GPP RAT of the first PLMN; and determining, for accessing the data service or both the data service and the voice service, one of a second 3GPP RAT of the first PLMN, the first 3GPP RAT of a second PLMN, a N3GPP RAT of the second PLMN, or an N3GPP RAT of the first PLMN

Abstract: A method for re-evaluating one or more user equipment route selection policy (URSP) rules associated with a user equipment (UE) in communication with a network entity is disclosed. The method comprises receiving, at a user equipment non-access stratum (UE NAS) layer, a back-off timer from the network entity. The back-off timer is related to non-initiation of a packet data unit (PDU) session associated with an application within the UE. The method comprises initiating, by the UE, the PDU session associated with the application. The method comprises indicating, by the UE NAS layer, an expiry of the back-off timer. The method comprises, upon the expiry of the back-off timer, re-evaluating, by the UE, the one or more URSP rules to determine whether a change of association of the PDU session with the application is required.

Abstract: The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system. A method for Network slice admission control for interworking with an Evolved Packet Core Network (EPC) in a wireless network by a Session Management Function-Packet Data Network Gateway (SMF-PGW-C) is provided. The method includes detecting that at least one UE transfers a Packet Data Network (PDN) connection or a Protocol Data Unit (PDU) session from a N1 mode to a S1 mode during an intersystem change. Further, the method includes determining that an EPC counting is not required for a network slice of the wireless network. Further, the method includes transmitting a message to a Network Slice Admission Control Function (NSACF) in the wireless network to update or reduce a number of User Equipments (UEs) per network slice and a number of PDU sessions per network slice.

Abstract: A method and system in the User Equipment (UE) for maintaining rejected network slice selection assistance information (NSSAI) for Single Network Slice Selection Assistance Information (S-NSSAI) not available due to maximum number of UEs reached per access type. The method comprises receiving a Non-Access Stratum (NAS) message including at least one of a registration accept, registration reject or CONFIGURATION UPDATE COMMAND message along with at least one of rejected Single Network Slice Selection Assistance Information (S-NSSAI(s)) information and a cause for the S-NSSAI not available due to maximum number of UEs reached from a network. Thereafter, the method includes determining by the UE an access type on which the rejected S-NSSAI(s) is applicable based on the received S-NSSAI(s) information and then maintaining a storage of the rejected NSSAI for the S-NSSAI not available due to the maximum number of the UEs reached per access type based on the determination.

Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Methods and systems for managing bearer configuration of user equipment (UE) with Evolved-Universal Terrestrial Radio Access Network-New Radio-Dual Connectivity (E-UTRAN-NR-DC) (EN-DC) capability. The UE detects connectivity issues in the UE itself and in interfaces connecting between a NR network with the UE, a LTE network, or an EPC that require disabling NR capability of the UE. The bearer configuration is determined and updated based on the detected connectivity issues. The UE signals the LTE network about the disabling of NR capability, requests enabling of data transfer through bearers of a MCG bearers associated with the LTE network in a current MCG RRC session, and prevents addition of SCG bearers associated with the NR network. The UE recovers data in the SCG bearers, lost due the issues in the NR network, through the MCG bearers. The UE can send a Tracking Area Update (TAU) to indicate the disabling of NR capability if the connectivity issues persist.

Abstract: A method in a mobile station (MS) and an MS in a wireless communication network are provided. The method includes detecting an intersystem change from an S1 mode to one of an A/Gb mode and an Iu mode, detecting that a routing area update (RAU) has failed detecting that a successful generic location updating procedure has not been performed since the detected intersystem change, and triggering an MM specific procedure based on detecting that the RAU has failed and the successful generic location updating procedure has not been performed. The MM specific procedure corresponds to a location area update (LAU).
