Abstract
A mobile communication system can implement broadcasting control that generates broadcast information autonomously in a distributed manner, thereby obviating the need for an RNC (Radio Network Controller). Each base station has an IP address and a base station multicast address. Each base station sends its own system information to all base stations using the multicast address. Each base station generates its broadcast information from its own system information and the system information received from other base stations. Thus, it can generate the broadcast information autonomously in a distributed manner without using the RNC.
Claims26
A mobile communication system including multiple base stations that are interconnected two-dimensionally and offer radio communication services in individual service areas, each of said base stations comprising:
- information exchanging means for exchanging information about broadcast information with other base stations;
- and
- broadcast information generating means for generating broadcast information about a broadcasting area of said base station from information about broadcast information that is sent from said other base stations and obtained by said information exchanging means.
A distributed broadcast information control method in a mobile communication system including multiple base stations that are interconnected two-dimensionally and offer radio communication services in individual service areas, each of said base stations comprising the steps of:
- exchanging information about broadcast information with other base stations;
- and
- generating broadcast information about a broadcasting area of said base station from information about broadcast information that is sent from said other base stations.
A base station that offers radio communication services in a service area, said base station comprising:
- information exchanging means for exchanging information about broadcast information with other base stations;
- and
- broadcast information generating means for generating broadcast information about a broadcasting area of said base station from information about broadcast information that is sent from said other base stations and obtained by said information exchanging means.
