Voice over LTE - Wikipedia
VoLTE is based on the IP Multimedia Subsystem (IMS) architectural framework, with specific profiles for control and media planes of voice service. This facilitates VoLTE on the LTE wireless broadband service defined by GSMA in PRD IR.92. [4]
IMS VoLTE Architecture - Voice Over LTE Tutorial - 3GLTEInfo
IMS VoLTE Architecture. The idea of IMS is old, but after it’s deployment with LTE users and operators can harness the true power of IMS. IMS – IP Multimedia Subsystem is a standalone system. It resides out of the LTE network and connected to PDN Gateway through SGi interface. The EPC has three main functional elements.
What is the difference between IMS and VoLTE? – Commsbrief
2021年11月20日 · 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).

2020年6月7日 · IMS is a standalone system which resides out of the LTE network and connected to PDN Gateway or PGW through SGi interface. The idea of IMS is very old & was very popular around Year 2004, this used to be a failed Concept prior to support of VoLTE Services.
VoLTE (Voice over LTE) - Networks
What is VoLTE? VoLTE stands for ‘Voice over Long Term Evolution‘. Utilising IMS technology, it is a digital packet voice service delivered over IP via an LTE access network. Voice calls over LTE are recognised as the industry-agreed progression of voice services across mobile networks, deploying LTE radio access technology.
Communication services (VoLTE/VoNR) - 3GPP
VoLTE and VoNR are supported by the IMS networks over EPS and 5GS respectively. The Figure below shows a simplified architecture where standalone 4G and 5G networks are connected to IMS networks in order to provide VoLTE and VoNR services to a non-roaming user.
