Traffic Operation Overview in LTE

In LTE (Long-Term Evolution), traffic operations involve the management of data traffic within the network, ensuring efficient communication between User Equipment (UE) and the Evolved Packet Core (EPC). Here’s an overview of traffic operations in LTE: Data Transmission: LTE supports high-speed data transmission, enabling a variety of services such as web browsing, video streaming, and … Read more

Radio Bearer in LTE

Radio Bearer in LTE In Long-Term Evolution (LTE) wireless communication, a “Radio Bearer” serves as a crucial link between the user equipment (UE) and the evolved NodeB (eNodeB), facilitating the exchange of data. Radio Bearers are classified into two main categories: Control Radio Bearers (CRBs) and Data Radio Bearers (DRBs). CRBs are responsible for transmitting … Read more

EPS Bearer Terminology in LTE

EPS Bearer Terminology in LTE This article breaks down key concepts, including Quality of Service, GBR (Guaranteed Bit Rate) Bearers, Non-GBR Bearers, and crucial parameters like QoS Class Identifier (QCI) and Allocation and Retention Priority (ARP). Quality of service GBR bearer: Guaranteed bit rate Non-GBR bearer: No guaranteed bit rate Establishment time Default bearer Established … Read more

What is EPS Bearer in LTE?

Eps bearer LTE EPS is a connection-oriented transmission network and, as such, it requires the establishment of a “virtual” connection between two endpoints (e.g. a UE and a PDN-GW) This virtual connection is called an “EPS Bearer” It provides a “bearer service”, i.e. a transport service with specific QoS attributes. The LTE QoS parameters associated … Read more

Implementation Margin in LTE

Implementation margin is used to include non-ideal receiver effects such as channel estimation errors, tracking errors, quantization errors, and phase noise.  This implementation margin or sensitivity degradation can be used to apply some margin to the link budget to account for devices from other vendors that may have larger tolerances from the specifications or for … Read more

QoS Parameters of LTE

The QoS Class Identifier (QCI) is a scalar that is used as a reference to access node-specific parameters that control bearer level packet forwarding treatment (e.g. scheduling weights, admission thresholds, queue management thresholds, link layer protocol configuration, etc.). The Allocation and Retention Priority (ARP) primarily allows one to decide whether a bearer establishment request can … Read more
