摘要： 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.

摘要： Systems and methods are described for simultaneously accessing a plurality of services on Wi-Fi. The method comprises registering a first and second Media Access Control (MAC) identification (ID) with a first and second IP Multimedia System (IMS), by use of a User Equipment (UE). The UE comprises a first MAC ID associated with a first Subscriber Identification Module (SIM) card and a second MAC ID associated with a second SIM card. Use of a first service through a first Access Point (AP) without interrupting a second service may be available with registration of a first and second MAC ID

摘要： 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.

摘要： A method and system for minimizing delay in circuit-switched fallback (CSFB) procedure is disclosed. The disclosed method provides two different approaches for optimizing the delay during the CSFB procedure. In the first approach, user equipment (UE) receives a Location Area Identifier (LAI along with the Radio Access Technology (RAT) information from the network (LTE network). The UE uses the received RAT information from the network for switching to the target Radio Access Network (RAN) without informing to the LTE network. In another approach, the UE obtains the RAT information by performing a background scan in idle mode, when the UE receives LAI without RAT information from the network.

摘要： Methods and User Equipment (UE) for managing IMS call over LTE in SRVCC area are provided. The method may include detecting, by an IMS client, that the IMS call over LTE is in an alert state, and a Radio Resource Control (RRC) reconfiguration cells are configured for the IMS call over LTE. Further, the method may include initiating by the IMS client a timer with a value less than a data inactivity timer value from a network entity. Further, the method may include detecting by IMS client that the timer has expired before establishing the IMS call over LTE and restarting by the IMS client the timer. Furthermore, the method may include sending by the IMS client a Session Initiation Protocol (SIP) message to the network entity.
