  • Radio telephone system
    Patent number: 6625452
    Abstract: A DECT-like radio telephone system in which a base station alerts the handsets of the system to an incoming call by transmitting a signal analogous to {LCE-PAGE-REQUEST} signal of a type that specifies no single handset. In response to the signal, the handsets activate alerting means to alert users of the handsets to the need to answer the call. The use of an {LCE-PAGE-REQUEST} signal avoids the need for DLC (Dynamic Link Control) links to be established between the handsets and the base station when the handsets are to be alerted to the call.
    Type: Grant
    Filed: August 6, 2002
    Date of Patent: September 23, 2003
    Assignee: Nokia Mobile Phones Ltd.
