RTT (Round-Trip Time) in Mobile Networks
RTT (Round-Trip Time) refers to the time it takes for a data packet to travel from a source device to a destination, and back again.
In more detail, RTT in a mobile network is the time it takes for a data packet to travel from the mobile phone to the remote server. And then the server process and respond to received data packet. And then the server response travels back from the remote server to the mobile phone.
A lower RTT values is generally preferred in mobile networks. This is because it indicates a more responsive and efficient network connection. And this results in better user experience.

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…
