Abstract: Embodiments herein provide a method for maintaining service continuity by a User Equipment (UE) in a wireless communication system. The method includes detecting, by the UE, a change in location during a mobility of the UE from one tracking are to another tracking are within a radio access technology which is referred here as a first radio access technology. Further, on receiving the Registration or Tracking area reject from the core network of first radio access technology, the method includes initiating, by the UE, Initial Registration Request or Initial Attach Request procedure, wherein the UE sends an Registration Request or Attach Request message with other registered radio access technology information referred here as second radio access technology to a core network associated with the first radio access technology.

Abstract: Embodiments herein provide a method for providing 5G services to user equipment (UE) (100) in a wireless communication network. The method comprising registering, by the UE (100), to a 5G network with a usage setting as voice centric and detecting, by the UE (100), an unavailability of at least one of a voice over long term evolution (VOLTE) service and a voice over new radio (VOLAR) service at the UE (100). Further, the method includes configuring the UE (100) to operate in one of a single radio 5G (SR5G) mode, an evolved-Universal Terrestrial Radio Access (E-UTRAN) New Radio-Dual Connectivity (ENDC) mode and provide data services dynamically on one of a 4G network and a 5G network.

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. The various embodiments of the present invention disclose a method of handling control plane data in a wireless network, the method comprises sending, by a user entity (UE), a non-access stratum (NAS) message along with an indication data to a mobility management (MM) core network entity. The MM core network entity processes the received NAS message and the indication data. The MM core network entity determines status of network congestion upon processing the processed NAS message.

Abstract: Disclosed is a method for handling cell selection in a multiple radio access technology dual connectivity (MR-DC) system, including scanning, by a user equipment (UE), at least one frequency, identifying, by the UE, a first cell supporting an MR-DC based on the scanned at least one frequency, and camping, by the UE, to the identified first cell.

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. Embodiments herein provide a method and UE for optimizing resources of wireless communication network while providing 5G services.

Abstract: A method for enabling a network selection during change in a location of a user equipment (UE) comprises of performing an emergency camping on a first PLMN during a change in location of the UE from a first network to a second network in a power ON mode, identifying a mobile country code and a mobile network code of the first available network from a system information block (SIB) detected from the first network during the emergency camping, determine whether a registered public land mobile network (RPLMN) of the UE is same as a network area of the first available network by comparing the identified MCC and MNC with information of a PLMN database stored in the UE, and determining at least one PLMN from a plurality of priority PLMNs of the second network from the PLMN database if the RPLMN is different from the network area of the first available network.

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 and an apparatus for managing a non-integrity protected message. The method includes receiving a reject cause message from a first public land mobile network (PLMN) in response to a transmission of a registration request message to the first PLMN, re-attempting the transmission of the registration request message to one of the first PLMN and a second PLMN, receiving registration accept message from one of the first PLMN and the second PLMN in response to the re-attempting, and resetting a counter maintained for the first PLMN by the UE.
