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...
