RTCP in IMS network
RTCP referes to "Real-Time Control Protocol". And it is a companion protocol to RTP prototcol.
RTCP provides feedback to different nodes in the RTP session, about the quality of the data stream between them. It reports parameters, such as packet loss, delay, and jitter.
RTCP reports can be used to provide feedback about congestion in the network, allowing the RTP senders to adapt their transmission rates accordingly.
Those reports can also be used by service providers, to monitor and ensure the quality of the audio/video streams, enabling service providers to provide a satisfactory user experience.

VoLTE (Voice over LTE) Introduction
While the UE attached to LTE network, the UE can initiate, or receive a voice or a video call. The UE achieves this, by connecting to an external network, which is the 'IMS' network. We can call this, Voice over LTE (VoLTE). This is exactly like when you would like to create a call, while…

What is an ‘EPS Bearer’ in LTE ?
During 'LTE attach' procedure, the network establishes this EPS Bearer between the UE and the PGW. The PGW assigns an IP address for this Bearer. The UE uses this IP address, in order to communicate with the PDN. In addition, the PGW assigns a QoS for this Bearer, which guarantees the QoS for the data…

QoS ‘Quality of Service’ in GPRS
QoS refers to 'Quality of Service'. After 'PDP context activation' procedure completes, a 'PDP context' shall exist on the MS, the SGSN, and the GGSN. In addition, the GGSN assigns a QoS for this 'PDP context'. This QoS describes the priority that the nodes shall give to traffic belonging to this 'PDP context'. The subscription…
