Embodiment Construction

[0132] The invention can be implemented in a mobile communication system such as UMTS (Universal Mobile Telecommunications System) developed by 3GPP. Not limited thereto, the present invention is also applicable to various communication systems working with different standards.

[0133] The present invention proposes a method in which a wireless communication system can provide multimedia services to a designated group of terminals through a public wireless channel, the method designating a radio suitable for transmitting the public wireless channel of designated multimedia service data resources, and send various specified multimedia services to a terminal group.

[0134] In the present invention, different MBMS services in a cell may have different predetermined parameters. The reservation may indicate whether the corresponding MBMS service data (referred to as "MBMS data" herein) has been sent, and the reservation parameter includes time information indicating the time of ...

Abstract

A multimedia service of a UMTS (Universal Mobile Telecommunications System) is disclosed. When UTRAN provides an MBMS service, it designates time at which each data for MBMS service is transmitted and transmits the corresponding time information to a terminal group which desires to receive a specific MBMS service. Accordingly, a terminal of the terminal group receives the MBMS service data during a section of the corresponding time information and also receives a control signal or other service than the MBMS service at other time.

Description

technical field [0001] The present invention relates to the multimedia broadcasting / multicasting service of UMTS (Universal Mobile Telecommunications System), in particular, relates to the predetermined sending method of MBMS data. Background technique [0002] The Universal Mobile Telecommunications System (UMTS) is derived from the well-known Global System for Mobile Telecommunications (GSM) standard [0003] Extended third-generation mobile communication system. This standard is a European standard whose purpose is to provide an improved mobile communication service based on the GSM core network and Wideband Code Division Multiple Access (W-CDMA) technology. [0004] figure 1 A general UMTS network structure is shown. [0005] as figure 1 As shown, the UMTS can be simply divided into a terminal, a UTRAN and a core network. [0006] The UTRAN includes one or more Radio Network Subsystems (RNS). Each RNS includes an RNC and one or more Node Bs managed by the RNC. [...
