QoS Mechanism in EPS
"To adapt to the development of mobile communication technologies in the next 10-year timeframe and better meet an ever-increasing demand for data services, 3GPP has started the Long Term Evolution (LTE) and System Architecture Evolution (SAE) study projects. In view of the high-speed and bursty feature of future data services, the Evolved Packet System (EPS) makes quite a few enhancements and improvements in Quality of Service (QoS). By introducing such technologies as default bearer and aggregate resource scheduling, the EPS truly realizes the objective of ""Always Online"" for users, improves data rates and thus enhances user experience ultimately. Furthermore, an appropriate mapping between the EPS QoS Class Identifier (QCI) parameter and Universal Mobile Telecommunication System (UMTS) QoS parameter is designed regarding future interoperability scenario between UMTS Terrestrial Radio Access Network (UTRAN) and Evolved UTRAN (E-UTRAN)."
