Abstract

A common Iub transport for transmitting the same multimedia traffic from a radio network controller (RNC) (4a-c) to a base station device (5a-e) in a radio access network (3) via an Iub interface (9) The data block is thus forwarded to a mobile terminal (7) participating in a multimedia service located in a cell (6a-h) served by said base station device.

Description

technical field [0001] The present invention relates to the optimized transmission of a media stream, which is transmitted from a radio network controller to a base station device via an Iub interface, and includes multimedia data, for example in 3GPP (Third Generation Partner Program) within MBMS (Multimedia Broadcast / Multimedia Services). Background technique [0002] 3GPP standards relate to technologies based on radio access networks such as UTRAN (Universal Mobile Telecommunications (UMTS) Terrestrial Radio Access Network), which is a radio access network that provides W-CDMA (Wideband Code Division Multiple Access) to mobile terminals Architecture. Telecommunication systems according to 3GPP standards offer higher transmission bit rates, high service flexibility and multiple simultaneous connections to mobile terminals, and are able to offer new types of services to users. MBMS included in the 3GPP standard provides broadcasting / multicasting of various multimedia inf...
