Benefits of technology

The present invention provides a method for transmitting multimedia data in a digital wireless communication network using a single data stream between the network controller and the base station. This method improves the use of available data transmission capacity and enables separate control of transmission power for each user equipment. The invention also provides for the use of point to point or point to multipoint bearers for transmitting the multimedia data to multiple user equipment in the same radio cell, depending on the number of active user equipment per radio cell or per base station. The technical effects of the invention include improved efficiency and flexibility in transmitting multimedia data in wireless communication networks.

Problems solved by technology

A disadvantage of the broadcast mode is that power control cannot be performed individually for the user equipment.

Embodiment Construction

[0025]FIG. 1 shows a block diagram of wireless telecommunication system, such as a UMTS-type system. Telecommunication system 100 has radio network controller (RNC) 102. Radio network controller 102 has control module 104 for controlling node-B 106.

[0026]Node-B 106 has control module 108 for controlling the internal operation of node-B 106 and for receiving control commands from control module 104 of radio network controller 102.

[0027]Preferably the interface between radio network controller 102 and node-B 106 is based on the lub standard definition. The lub interface is a logical interface for the interconnection of Node-B and Radio Network Controller components of the UMTS Terrestrial Radio Access Network (UTRAN). The radio network control signaling between these nodes is based on the Node B application part (NBAP). The control commands from Radio Network Controller to the Node-B can be transmitted by using the signaling transport related to NBAP signaling across the lub Interface...

Abstract

A method of providing a multimedia multicast service in a digital wireless communication network, the network having a network controller for controlling of at least one base station, comprising establishing a single data stream from the network controller to the base station for transmitting of multimedia data, by means of a single lub link or transport bearer and establishing a separate communication link and a separate data queue for each user equipment in a radio cell of the base station which requests the multimedia data.

Description

[0001]This is a continuation of application Ser. No. 10 / 893,389 filed Jul. 19, 2004. The entire disclosure of the prior application Ser. No. 10 / 893,389 is hereby incorporated by reference.FIELD OF THE INVENTION[0002]The invention is based on a priority application EP03292005.0 which is hereby incorporated by reference.[0003]The present invention relates to the field of telecommunications, and more particularly without limitation, to multimedia multicast and multimedia broadcast services.BACKGROUND AND PRIOR ART[0004]Point to multi point services exist today which allow data from a single source entity to be transmitted to multiple end points. These services are expected to be used extensively over wireless networks. In particular there is a strong interest to provide multimedia broadcast / multicast service over 3G networks.[0005]The multimedia broadcast / multicast service (MBMS) which is considered for the universal mobile telecommunications systems (UMTS) is a unidirectional point-to...
