    Abstract: The present disclosure provides a method for improving call performance in a wireless network. The method includes sending an invite request to a server to initiate a Voice over New Radio (VoNR) service, where the UE is connected with a first network entity, and where the invite request comprises a media feature tag. The method includes initiating an Evolved Packet System fallback (EPS FB) service timer based on the media feature tag and a quality of service (QoS) timer and establishing a call over a second network entity using a dedicated bearer when the EPS FB command is received from the server. The call is established over the second network entity using the dedicated bearer by sending a service request to the server and/or sending an update request to the server when the EPS FB timer is expired and the EPS FB command is not received from the server.

    Abstract: A method and system to use existing Non-access stratum (NAS) signaling connection for pending uplink signaling/data after Tracking Area Update Procedure (TAU) complete is disclosed. The proposed method handles the EPS Session Management (ESM), Short Message Service (SMS) or voice call or data when a User Equipment (UE) is waiting for TAU accept. The method allows UE to inform the network with specific Information Element (IE) in TAU complete message, so that the network will take the next action. This will help to provide quick services to the user. Using the “CONN REQ TYPE” IE, in TAU complete, to handle all abnormal Cases for Circuit Switches (CS) services/data services in E-UTRAN (Evolved UTRAN) network.

    Abstract: According to a method of preventing call drop in voice communication network, a session is established for voice call initiated between a first terminal and a second terminal. The method includes receiving a first indication that the first terminal is entering a low-signal area. Further, the method includes disabling one or more media inactivity timers for retaining the session. Furthermore, the method includes storing one or more network parameters when one of the session is retained or when the session is released. Thereafter, the method includes receiving a second indication that the first terminal has exited the low-signal area. The voice call is resumed on the session based on the stored network parameters, when the session is retained upon enabling the respective one or more media inactivity timers. The voice call is re-initiated on a new session, based on the stored network parameters when the session is released.
