What is IMS in LTE network?
IP Multimedia Subsystem or IMS is a standards-based architectural framework for delivering multimedia communications services such as voice, video and text messaging over IP networks.
Is IMS and VoLTE same?
IMS (IP Multimedia Subsystem) is a network element that works alongside 4G LTE core network (Evolved Packet Core – EPC) to enable Voice over LTE (VoLTE) in 4G networks; VoLTE is an IP-based technology enabled by EPC and IMS in packet-switched LTE networks to facilitate voice calls and texts (SMS).
What is IMS service on Android phone?
To support this specification, Android provides an IMS service entitlement feature that allows a service provider to inform mobile devices of the status of IP Multimedia Subsystem (IMS) network services. This entitlement feature allows the device to query the carrier entitlement server as defined by the GSMA TS.
