Embodiments disclosed herein relate to methods for handling a resource in a wireless network by a UE. The method includes receiving a reject cause message from a network entity. The UE does not support a redirected radio access technology (RAT) indicated in the reject cause message. Further, the method includes considering the reject cause message to represent an abnormal case and performing at least one action based on the abnormal case. The method can be used for enabling enhanced NAS procedure in CIoT devices. The method can also be used to indicate the change in support of CP/UP preference when both CP and UP CIoT optimization are supported, so as to reduce the signalling overhead in the wireless network, improve the UE behavior and NAS procedural efficiencies.

Methods, user equipment, and network entity for handling resource in wireless network

A method is provided for completing a registration procedure in a fifth generation (5G) network, comprising transmitting, by a user equipment (UE), a registration request message to the 5G network, the registration request message initiating a first registration procedure, starting, by the UE, a connection release timer in response to occurrence of a plurality of events; meeting, by the UE, at least one of a plurality of conditions; stopping, by the UE, the connection release timer in response to the meeting the at least one of the plurality of conditions; and performing, by the UE, a local release of a signaling connection in response to the meeting the at least one of the plurality of conditions if the UE is in a connected state.

Methods and systems for optimization of signaling and connection management in non-access stratum

Embodiments herein disclose a method for handling dual registration of user equipment (UE) in a wireless communication system. The method includes registering the UE on a fourth generation Radio Access Technology (4G RAT) and a fifth generation RAT (5G RAT). Further, the method includes determining, by the UE, an occurrence of at least one event. Further, the method includes suspending, by the UE, the registration on the 5G RAT. Further, the method includes performing, by the UE, communication using the registration on the 4G RAT.

Method and user equipment for handling dual registration in wireless communication system

A method and apparatus of an AMF controller in a wireless communication system are provided. The method and apparatus include: registering a first SIM based on a first registration request message and registering a second SIM based on a second registration request message which has a GUTI for the first SIM. Further, the method and apparatus include: receiving at least one of downlink data and signaling information for the second SIM when a N1 NAS is in CM-Connected state for the first SIM, and transmitting a NAS message indicating at least one of the downlink data and the signaling information for the second SIM over the N1 NAS connection of the first SIM.

Method and apparatus for indicating MT-service for multi-SIM UE

A method for selecting a Public Land Mobile Network (PLMN) in a wireless communication system by a User Equipment (UE), the method includes detecting, by the UE, that the UE is operating in an interworking mode, triggering, by the UE, a manual scan in the interworking mode for acquiring a list of PLMNs in the wireless communication system, and causing, by the UE, a display to output the list of PLMNs in response to the triggering.

Selecting PLMN in wireless communication system

NAS signaling between a UE and a server is enhanced by performing one of: sending a registration complete message to the server using existing NAS signaling and without starting a release timer in response to receiving an RC_ID deletion IE in a registration accept message; and not sending the registration complete message to the server in response to receiving the RC_ID deletion IE in the registration accept message. A registration procedure is reinstated based on a stored RC_ID.

Method and UE for enhancing NAS signaling in radio capability signaling optimization

A user equipment (UE) may ascertain an incapability of the network to process a pending uplink signal based on a registration acceptance message from the network. For instance, a registration acceptance message from the network, that may indicate the network is not capable of processing the pending uplink signal service. Accordingly, upon ascertaining the incapability of the network to process the pending uplink signal, the UE may release a connection (e.g., a N1 Non-Access Stratum (NAS) signaling connection) between the UE and the network, where the connection is based on camping of the UE at a cell corresponding to the radio access network (RAN) (e.g., the NG-RAN) of the network. Alternatively, the UE may initiate one of an implementation dependent timer and a release timer (e.g., a T3540 timer) to release the connection (e.g., to release the N1 NAS signaling connection).

Systems and methods to avail services of a network

A method disclosed herein includes selecting, by the UE, a SNPN for registration, on the SNPN access mode being enabled. The method includes disabling, by the UE, the SNPN access mode, if the selected SNPN does not support at least one emergency service. The method includes enabling, by the UE, a Public Land Mobile Network (PLMN) selection mode to select a PLMN cell supporting the at least one emergency service, on the SNPN access mode being disabled. The method includes performing, by the UE, the at least one emergency service by camping on the selected PLMN cell. The method includes enabling, by the UE, the SNPN access mode for performing a SNPN selection procedure, on completion of the at least one emergency service.

Methods and systems for managing SNPN access mode

A method performed by a User Equipment (UE) for managing a failure in a registration for accessing a network slice, and the UE including processing circuitry configured to perform the method, are provided. The method includes sending a registration request message to a first wireless network while the UE is in a tracking area of a registration area, the registration request message including a Single Network Slice Selection Assistance Information (S-NSSAI) corresponding to the network slice, receiving a registration reject message from the first wireless network indicating that the network slice is unavailable, storing a Tracking Area Identifier (TAI) of the tracking area to a rejected list based on the TAI of the tracking area being included the registration reject message, and establishing a connection with a second wireless network in response to the receiving.

Method and user equipment for managing failure in registration for accessing network slice

A method for connecting to a Registered Public Land Mobile Network (RPLMN) after receiving an accept message with limited service from a user selected CSG cell, which is associated to a different PLMN than the RPLMN during manual CSG selection mode is disclosed. The method includes connecting to the RPLMN based on the availability of the user selected CSG cell in UTRAN. If the user selected CSG cell is not available in UTRAN, then the method includes connecting to the RPLMN by the UE using the stored duplicate value of the RPLMN. If the user selected CSG cell is available in UTRAN, then the method includes sending an ATTACH request to the user selected CSG cell without disabling the EUTRA capabilities. If the ATTACH request is failed, then the method includes connecting to the RPLMN using the stored duplicate value of the RPLMN.

Method for reducing battery power consumption of user equipment (UE) during manual CSG selection

Embodiments herein disclose a method for service prioritization in an electronic device comprising a plurality of SIMs associated with a single RF resource within the electronic device. The method includes sending, by an RF controller of the electronic device, a response to a second SIM to access the service associated with a second network entity. Further, the method includes configuring, by the RF controller, a signalling message comprising a category of service. The category of service indicates a priority of the service to be accessed by the second SIM. Further, the method includes sending the signalling message comprising the category of service to the second network entity.
