Methods and apparatuses for integration of broadcast transmission with access infrastructure of a public network for mobile communications
First Claim
1. In a cellular telecommunications network havingan access subsystem including a plurality of base stations and one or more controllers of said base stations,a transport subsystem operatively connected to said controllers of said base stations for implementing routing and switching functions of said cellular telecommunication network,a plurality of user terminal systems each of which is operatively connected to one of said base stations for accessing said telecommunication network,the improvement wherein said cellular communication network comprises,broadcast means for transmitting broadcast information signals from at least one source external to said cellular telecommunications network, andreceiver means operatively connected to said plurality of base stations for directly receiving said information signals from said broadcast means, whereby said broadcast information signals can be broadcasted from said base stations to said user terminal systems without burdening said transport subsystem,and access subsystem comprises picocells.

Abstract
A telecommunications network for mobile users includes a user subsystem and a transport subsystem connected to an access subsystem. The access subsystem provides a user access communications interface and a transport access communications interface for exchange of information among the subsystems. The access subsystem is identified with a coverage area of the cellular telecommunication network. The access subsystem is associated with interconnection means in order to receive second information signals broadcast from one or more geostationary satellites and send them via the telecommunications network for mobile users to users located within the coverage area of the mobile telecommunications network.

14. A method of enabling a plurality of users, each of whom employs a respective user terminal system to individually communicate by first information signals which are switched and routed in a transport subsystem of a public cellular telecommunications network, to collectively receive second information signals on said user terminal systems, said public cellular telecommunications network having
an access subsystem for enabling said users to connect to said public cellular telecommunications network through a plurality of base stations, one or more controllers of said base stations, each of said controllers of said base stations being operatively connected to said transport subsystem for permitting bidirectional communication therebetween, said method comprising: -
broadcasting said second information signals from at least one source external to said cellular telecommunications network, receiving said information signals at a receiver remote from said transport subsystem, applying said received second information signals from said receiver to said base stations, and further broadcasting said second information signals from each of said base stations to one or more of said user terminal systems without increasing the burden on said transport subsystem beyond that resulting from said first information signal, said access subsystem comprising picocells. - View Dependent Claims (15, 16, 17, 18, 19, 20)
