Embodiment Construction

[0024] figure 1 The outline shows a part of the GSM system in which ATM-based cellular network elements are used as a preferred embodiment of the broadband cellular network equipment according to the present invention.

[0025] in figure 1 In, the Mobile Services Switching Center (MSC) 1 representing the first downlink transfer stage is connected to a predetermined port of the ATM switch 3. In addition, a base station controller (BSC) 2a is connected to other predetermined ports of the ATM switch 3. The output terminal of the ATM switch 3 is connected to a plurality of base stations (BTS) 4, which communicate with a specific one or more of each end user mobile station (MS) 5 as described above.

[0026] In this structure, the ATM switch 3 serves as a switching element and is controlled by the base station controller 2a.

[0027] figure 2 The ATM-based cellular network element is briefly described as the preferred embodiment of the broadband cellular network device.

Abstract

A broadband cellular network device comprises a cellular controller means adapted to control the distribution of cellular traffic consisting of asynchronous transfer mode cells in trunking mobile communication networks based on ATM technology, and an asynchronous transfer mode switching means controlled by said cellular controller means and adapted to multicast said cellular traffic to downlink base transceiver stations using multicast properties of the asynchronous transfer mode switching means.

Description

Technical field [0001] The present invention relates to cellular multicast in a mobile communication system, and in particular to an asynchronous delivery mode cellular network device that uses the multicast characteristics of an asynchronous delivery mode switching element to perform cellular multicast in the downlink direction. Background technique [0002] In recent years, the Global System for Mobile Communications (GSM) and other cellular networks have developed rapidly on a global scale. The corresponding increase in the number of users leads to a corresponding increase in bandwidth on the relay network of the cellular system, such as the base station subsystem (BSS) in GSM. [0003] In addition, the integration of mobile stations (MS), such as mobile phones, and data communications has led to the emergence of new data services, such as short message (SMS), or access to the Internet through mobile stations. Providing the bandwidth required for these new data services throug...
