Support of Mobile TV Over an HSPA Network

摘要

This paper describes a quality of service (QoS) implementation in the UMTS Terrestrial Radio Access Network (UTRAN) to commercialize mobile television (TV) services with current High Speed Packet Access (HSPA) commercial devices, which do not support a streaming traffic class as defined by the 3rd Generation Partnership Project (3GPP). This implementation allows the mobile operators to offer a high quality of service for the end user in terms of reducing the need for re-buffering during the mobile TV session, while minimizing the impact of the service on the overall radio cell capacity. System level simulations relying on a Tier 1 operator use case have been generated to quantify the benefits streaming users experience due to this QoS implementation in the presence of background traffic in the same radio cell. The impact in terms of radio cell capacity is also evaluated.
