Patent ID: 8611952

Claim:
A mobile communications radio receiver for multiple radio network operation, comprising: an RF unit configured to generate a first down-converted signal from a radio signal received from a first radio network and a second down-converted signal from a radio signal received from a second radio network, wherein the first radio network and the second radio network are different radio networks; a first receiving unit comprising a paging indicator channel demodulator configured to demodulate a paging indicator channel of the first radio network based on the first down-converted signal; a second receiving unit comprising a pilot channel demodulator configured to demodulate a pilot channel of the second radio network based on the second down-converted signal, wherein the second receiving unit does not comprise a paging indicator channel demodulator configured to demodulate a paging indicator channel of the second radio network; and a first data connection configured to couple paging information contained in the second down-converted signal to an input of the paging indicator channel demodulator of the first receiving unit, wherein the paging indicator channel demodulator of the first receiving unit is configured to demodulate the paging indicator channel of the first radio network and the paging indicator channel of the second radio network.
