LTE (Long-Term Evolution) introduces Quality of Service (QoS) to ensure that different types of traffic receive appropriate treatment in terms of priority and resource allocation. To achieve this, LTE defines QoS Class Identifiers (QCIs) that classify traffic into different classes. Each QCI represents a specific level of service that is suitable for different types of ...

S11 Interface in LTE: The S11 interface in Long-Term Evolution (LTE) networks plays a crucial role in facilitating communication and information exchange between two key elements: the Serving Gateway (SGW) and the Packet Data Network Gateway (PGW). It is a critical interface within the LTE Evolved Packet Core (EPC) architecture, responsible for routing user data ... Read more
A parallel 3GPP R8 project to LTE and SAE is the Evolved High Speed Packet Access, eHSPA, project (also referred to as HSPA+). The proposed eHSPA features represent a logical evolution from today’s HSDPA and HSUPA systems. Roughly speaking, the eHSPA project focuses on three areas: • Optimising HSPA for real-time packet data services, like ... Read more
