摘要 |
The present invention provides a wireless telecommunications network comprising at least one base station transmitter and a plurality of user equipments able to receive radio messages from the at least one base station transmitter. The network is adapted to transmit a notification message to at least a sub-group of the user equipments, a first part of the message comprising a representation from which a user equipment can determine whether its present location is within a certain geographical area. Once the user equipment has determined that it is within this area a second part of the message is read. This second part preferably includes a reason for the notification, e.g. a description of an emergency. To read this message the user equipment may be required to access the network so that the use of the service can be billed.
