A method for improving call performance in a wireless network, the method comprising: sending, by a User Equipment, UE, an invite request to a server in the wireless network to initiate a Voice over New Radio, VoNR, wherein the UE is connected with a first network entity of the wireless network, and wherein the invite request comprises a media feature tag; initiating, by the UE, an Evolved Packet System, EPS, fallback, EPS FB, timer, based on the media feature tag, and a Quality of service, QoS, timer, wherein the media feature tag is received by the UE from the server as a response of the invite request; determining, by the UE, whether an EPS FB command is received from the server, wherein the EPS FB command indicates a handover, HO, from the first network entity to a second network entity; and performing, by the UE, one of: establishing, when the EPS FB command is received from the server, a call over the second network entity using a dedicated bearer, wherein the dedicated bearer is allocated by the server, and establishing, when the EPS FB command is not received from the server and the EPS FB timer is expired, the call over the second network entity using the dedicated bearer by at least one of sending a service request to the server and sending an update request to the server, wherein the media feature tag indicates that at least one of an EPS FB and the VoNR is supported by the UE and the server during an Internet Protocol, IP, Multimedia Subsystem, IMS, registration process, wherein initiating, by the UE, the EPS FB timer based on the media feature tag, comprises: performing, by the server, one of: recommending the EPS FB to the UE when the server supports the EPS FB, wherein the UE enables the EPS FB timer, and recommending the VoNR to the UE when the server supports the VoNR, wherein the UE disables the EPS FB timer. sending, by a User Equipment, UE, an invite request to a server in the wireless network to initiate a Voice over New Radio, VoNR, wherein the UE is connected with a first network entity of the wireless network, and wherein the invite request comprises a media feature tag; initiating, by the UE, an Evolved Packet System, EPS, fallback, EPS FB, timer, based on the media feature tag, and a Quality of service, QoS, timer, wherein the media feature tag is received by the UE from the server as a response of the invite request; determining, by the UE, whether an EPS FB command is received from the server, wherein the EPS FB command indicates a handover, HO, from the first network entity to a second network entity; and performing, by the UE, one of: establishing, when the EPS FB command is received from the server, a call over the second network entity using a dedicated bearer, wherein the dedicated bearer is allocated by the server, and establishing, when the EPS FB command is not received from the server and the EPS FB timer is expired, the call over the second network entity using the dedicated bearer by at least one of sending a service request to the server and sending an update request to the server, wherein the media feature tag indicates that at least one of an EPS FB and the VoNR is supported by the UE and the server during an Internet Protocol, IP, Multimedia Subsystem, IMS, registration process, wherein initiating, by the UE, the EPS FB timer based on the media feature tag, comprises: performing, by the server, one of: recommending the EPS FB to the UE when the server supports the EPS FB, wherein the UE enables the EPS FB timer, and recommending the VoNR to the UE when the server supports the VoNR, wherein the UE disables the EPS FB timer. establishing, when the EPS FB command is received from the server, a call over the second network entity using a dedicated bearer, wherein the dedicated bearer is allocated by the server, and establishing, when the EPS FB command is not received from the server and the EPS FB timer is expired, the call over the second network entity using the dedicated bearer by at least one of sending a service request to the server and sending an update request to the server, wherein the media feature tag indicates that at least one of an EPS FB and the VoNR is supported by the UE and the server during an Internet Protocol, IP, Multimedia Subsystem, IMS, registration process, wherein initiating, by the UE, the EPS FB timer based on the media feature tag, comprises: performing, by the server, one of: recommending the EPS FB to the UE when the server supports the EPS FB, wherein the UE enables the EPS FB timer, and recommending the VoNR to the UE when the server supports the VoNR, wherein the UE disables the EPS FB timer. recommending the EPS FB to the UE when the server supports the EPS FB, wherein the UE enables the EPS FB timer, and recommending the VoNR to the UE when the server supports the VoNR, wherein the UE disables the EPS FB timer.
