SYSTEM AT TELECOMMUNICATIONS NETWORK

摘要

The invention relates to a system at GSM which provides interactive control of broadband services. There are today systems which offer distributive services, for instance analog cable-TV, analog satellites and analog terrestrial TV-networks. A paradigm shift, however, has been initiated in connection with that digital transmissions have started, which make possible a more spectrum efficent transmission. This means, for instance, that a broadband service such as digital transmission of video channels can be developed by making it interactive. One solution can be to use the GSM-system. For example, services which require low capacity in uplink can utilize the SMS-function in GSM. At larger demand of bandwidth GSM's data services can be utilized, which however prevents calls when the telephone is used for interactive communication. The invention solves this problem by interactive traffic between the transmitting and receiving equipment being managed by an interactive centre (IC) which is arranged to execute wanted broadband service. IC in addition is in connection with a distributive centre (DC) for distribution of the broadband signals out on the telecommunications network.
