Method, network and device for information provision by using paging and cell broadcast services

摘要

Informing a number of users about an emergency or other situation of public interest is accomplished using a broadcast service. A specific identifier is used in a paging message for activating broadcast service in terminals. A terminal checks a received paging message with regard to the presence of the specific identifier and when detecting the specific identifier, switches to a broadcast mode for receiving broadcast content. The received broadcast emergency content is notified and/or displayed to the users of the terminals.
