    Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). Embodiments herein provide a method of User Equipment (UE) handover from a Source-Radio Access Network (S-RAN) to a Target-Radio Access Network (T-RAN). The method comprises detecting whether the S-RAN and the T-RAN both support UE (101) Radio Capability (URC) signaling optimization. Further, determining whether a URC information corresponding to a URC Identification (URC-ID) is available at the T-RAN. Furthermore, sending the URC information to the T-RAN upon determining un-availability of the URC information at the T-RAN, or sending the URC-ID to the T-RAN upon determining availability of the URC information at the T-RAN. Finally, performing handover procedure with the UE (101) using one of the URC-ID and the URC information.

    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein provide a method for handling a RPLMN during a disaster situation in a wireless network by a UE. In an embodiment, the method includes selecting RPLMN as PLMN with the disaster condition for accessing the disaster roaming services in response to determining that the RPLMN is included in a list of PLMNs with disaster condition for which disaster roaming services is offered by another PLMN and is allowable. In another embodiment, the method includes skipping the RPLMN and determining a PLMN with disaster condition for acessing the disaster roaming services in response to determining that the at least one PLMN is not included in the list of PLMNs with the disaster condition for which disaster roaming services is offered by the another PLMN or is not allowable.

    Abstract: Methods and apparatus for receiving downlink data packets over Non-Third Generation Partnership Project (N3GPP) access. A User Equipment (UE) is configured to manage the triggering of Service Request procedures for receiving N3GPP Mobile Terminating (MT) packets in a coverage area of N3GPP access from a 5th Generation (5G) network. A Service Request procedure is triggered by the UE if the UE detects that the UE is in the coverage area of N3GPP access and that the UE is in 5th Generation Mobility Management (5GMM)-IDLE mode over N3GPP access and the back-off timer has expired. The detection is based on the UE determining that an access stratum connection is established between the UE and the 5G network over N3GPP access.

    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein disclose methods and systems for providing services efficiently in a wireless communication network, following a disaster condition. According to various embodiments, a method performed by a user equipment (UE) connected to at least one public land mobile network (PLMN), the method comprising: identifying that a disaster condition is applied to the at least one PMLN; determining one or more PLMN among at least one available PLMN, and one or more registration type supported by the determined one or more PLMN, wherein the one or more registration type include information on a normal registration or information on a disaster roaming registration; and triggering a registration procedure based on the determined one or more registration type.

    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. According to an embodiment, the method comprises establishing at least one PDU connection in an S1 mode; performing an inter system change from the S1 mode to an N1 mode; and in case that a successful UE-requested PDU session modification procedure is not previously performed and the UE is in a 5GMM-REGISTERED.NON-ALLOWED-SERVICE state, performing a UE-requested PDU session modification procedure to report 5G session management (5GSM) capability of the UE after entering a 5GMM-REGISTERED.NORMAL-SERVICE state.

    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The present subject matter refers to a method for a user equipment (UE) including a multi-universal subscriber identity module (MUSIM) in a wireless communication system is provided. The method includes registering to a public land mobile network (PLMN) on both of a 3rd generation partnership project (3GPP) access network and a non-3GPP access network, receiving, from an access and mobility management function (AMF), a message while the 3GPP access network is in an idle state, in case that the message is received over the 3GPP access network, identifying the message is related to a voice service and in case that the message is received over the non-3GPP access network, identifying that the message is related to a non-voice service.
