Supporting concentrator in multiple paging channel environment
First Claim
1. A method for paging a communications device comprising the steps of:
- determining a first communication channel at a frequency f1 and at a first power level associated with a concentrator, the concentrator being capable of functioning as a base station, over which to transmit a message in a wireless protocol to a communications device; and
transmitting the message over the first communication channel at the first frequency f1 and at the first power level to the concentrator the concentrator being further capable of demodulating the message and re-modulating the message over a second communication channel using a frequency f2, a second power level and the same wireless protocol; and
receiving a concentrator-base station registration signal over the first communication channel wherein the frequencies f1 and f2 are not the same and the first power level is less than a power level associated with a signal transmitted directly to the communication device from a base station.

Abstract
A paging signal is detected where the paging signal is intended for a mobile-telephone having a paging channel frequency that is different than a paging channel frequency associated with a concentrator. A base station transmits a base station-to-mobile-telephone (BS-MT) paging message by including such BS-MT paging message in a base station-to-concentrator (BS-C) paging message. The BS-MT paging message includes a message portion and a mobile-telephone identifier portion, wherein the mobile-telephone identifier portion indicates the mobile-telephone to which the BS-MT paging message is intended. The BS-C paging message includes the MT paging message and a concentrator identifier portion for indicating the concentrator to which the BS-C is intended. The BS-C paging message is transmitted over a paging channel on a frequency f1 associated with the intended concentrator (i.e., concentrator through which the mobile-telephone is linked to the base station). The intended concentrator detects the BS-C paging message by monitoring its associated paging channel on frequency f1 for a BS-C paging message with a concentrator identifier portion indicating the concentrator. Upon detecting its BS-C paging message, the concentrator parses the BS-MT paging message from the BS-C message and transmits the BS-MT paging message to the intended mobile-telephone using a paging channel on frequency f2 being monitored by the mobile-telephone.
