Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method for coordinating an unavailability period parameter of User Equipment (UE) in wireless network is provided. The method includes determining, by an Application Function (AF) of a network apparatus in the wireless network, the unavailability period parameter for the UE based on at least one event to be performed at the UE. Further, the method includes sending, by the AF of the network apparatus, the unavailability period parameter for the UE to an Access and Mobility Management Function (AMF) of the network apparatus. Further, the method includes configuring the unavailability period parameter at the UE. In an embodiment, UE detects it has to execute the event, UE initiates a non-access stratum (NAS) procedure to indicate it will become unavailable by indicating the unavailability period parameter to the 5th generation core (5GC), 5GC forwards the unavailability period parameter to the AF, with this the co-ordination between UE, 5GC and AF is achieved.

Abstract: A method of handling an ongoing call performed by a UE in a wireless network is provided. The method includes initiating a voice over long term evolution (VoLTE) call in a 4th generation (4G) network, detecting that a 5th generation (5G) network entity has configured an inter radio access technology (I-RAT) measurement indicating a change from the 4G network to a 5G network based on identification of the 5G network by the UE, determining whether at least one of the UE or the 5G network does not support a voice over new radio (VoNR) call with a 5G cell in the 5G network, and performing one of delaying sending a measurement report until the VoLTE call is completed in response to determining that the at least one of the UE or the 5G network does not support the VoNR call, or sending the measurement report immediately for the 5G cell in response to determining that both the UE and the 5G network support the VoNR call.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein provide a method for continuity of modem service by a user equipment (UE). The method includes detecting modem restart at the UE (100). The method includes determining whether a wireless network (400) and the UE (100) supports a session and mobility management feature upon detecting the restart of the modem (150), and identifying SM-MM contexts used by the UE (100) for accessing the modem service upon determining that the wireless network entity (200) supports the session and the mobility management feature. The method includes transmitting a first signaling message comprising at least one of the SM context and the MM context to the wireless network entity (200) for the continuity of the modem service.

Abstract: Methods and/or systems for managing continuity of data flow in 5G networks. A UE may receive a message from a 5G network in response to a PDU session establishment request. The message indicates a failure to establish a PDU session with a first DNN and a first network slice. A PDU session may be established with at least one of a second DNN and a second network slice, if the PDU session is matching with a route selection descriptor applicable to data traffic to be routed through the PDU session. A non-CIoT device may receive a message from a 5G network in response to a service request. The message may indicate failure of a service request procedure, pertaining to a PDU session, such as due to insufficient user-plane resources. The PDU session may be closed and reestablished. If there is lower layer failure in 5G, a connection may be established with a 4G network for data transfer.
