    摘要： Server of a communication system having a broadcast communication network, a communication service server and a storage device, the server providing a plurality of media streams which can be transmitted in a service area of the broadcast communication network by the broadcast communication network. The server includes a determination device that interrogates parameter values from a storage device for each client situated in the service area, and receives data which are transmitted by the broadcast communication network, wherein the parameter values are used to determine which of the media streams are intended to be communicated to the respective client, and determines based on the parameter values which of the media streams are intended to be transmitted by the broadcast communication network in the service area. The server also includes a controller that controls the broadcast communication network such that the network transmits the media streams which are intended to be transmitted.

    摘要： System information data transfer within a mobile telecommunication system to ensure that a piece of user equipment always has the most up to date information. Data is sent to the user equipment and includes information indicating a time of change of the active system information. The user equipment can use the time of change information to verify whether the system information it has stored is the latest version of the system information.
