Is IMS and VoLTE same?

VoLTE stands for Voice over Long-term Evolution. Utilizing the IMS (IP Multimedia Subsystem) technology, it is a specific type of VoIP service designed into the LTE standard, which enables users to make voice calls while simultaneously using data network LTE.

What is VoLTE and RCS?

VoLTE (Voice over LTE) uses IP Multimedia Subsystem (IMS) and Rich Communication Suite (RCS) and its benefits include enhanced indoor coverage using Wi-Fi and one can extend its advanced communication services with WebRTC using the same IMS core as VoLTE.

What is IMS RCS?

IP Multimedia Subsystem (IMS) is the foundation for VoLTE, VoWiFi and Rich Communication Services (RCS). Service Providers can leverage IMS-based core infrastructure to deliver highly cost-effective and resilient communication applications. RCS is a communication protocol aimed at replacing Short Message Service (SMS).

What is IMS Signalling in LTE?

3.2. To support telephone signaling between the LTE network and telephone networks, the IMS uses SIP (Session Initiation Protocol). SIP is a standard protocol for establishing voice calls over IP networks. The code is open, and uses the ‘request-response’ model to allow communication sessions.

What is IMS service on mobile phone?

Android 9 introduces a new SystemApi interface called ImsService to help you implement IP Multimedia Subsystem (IMS). The ImsService API is a well-defined interface between the Android platform and a vendor or carrier-provided IMS implementation.

What is difference between VoLTE and RCS?

VoLTE i.e. Voice over LTE is achieved by integration of IMS subsystem with EPC, thus upgrading a LTE network to support seamless voice calling services on a LTE network. And RCS i.e. Rich Communication Suite is also know as advanced messaging/SMS which is run using a IMS subsystem in the network.

What is the difference between IMS and VoLTE?

IMS (Ip multimedia Subsystem) is a standard (concept) which introduces the concept of using Internet protocol (IP) for landlines and wireless packet communication. VoLTE is transferring voice over IP .

What is VoLTE and how does it work?

VoLTE stands for Voice Over LTE, which means when you make calls from a supported phone the voice call will be on LTE network. The existing concept of making voice call over a data network which skype/viber etc uses is called VoIP. But with VoLTE we get much better call quality and HD audio and video calls.

What is the difference between PCRF and IMS core?

When a UE starts a VoLTE call, the PCRF checks if the UE has a subscription to start VoLTE call. If the UE has VoLTE subscription, PCRF setup dedicated bearer for IMS services. IMS core handles session management and media control. IMS core has the following important nodes.
