Maximum Bitrate (MBR) in Mobile Networks
Maximum Bitrate is a key QoS parameter in mobile networks that helps to manage bandwidth allocation. It is a Quality of Service (QoS) parameter, that defines the maximum data rate of a specific service or traffic flow.
MBR allows the network to better manage its limited radio resources, especially during periods of high network usage or congestion, by limiting the maximum data rate for certain services.
Maximum Bitrate is not the same as the actual experienced data rate, as the actual data rate depends on various factors such as network congestion and device capabilities.

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…

LTE (4G) Network Architecture
LTE (4G) Network Nodes LTE refers to 'Long Term Evolution', and the architecture of the LTE (4G) network is as following, eNodeB The eNodeB is the 4G site that the UE connects to. It provides the radio interface to the UE. MME MME refers to 'Mobility Management Entity'. The MME is responsible for authenticating the…

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…
