摘要
A method is provided of a sensor sensing a mobile user terminal for cellular radio telecommunications, the user terminal being associated with any one of a plurality of networks, each network having a distinct carrier frequency band for radio signals. The method comprises: broadcasting a common signal at each of multiple carrier frequency bands; the user terminal receiving the signal in the associated carrier frequency band of its network; the user terminal checking information in the received signal, and upon determining that the information is acceptable to allow connection to the sensor, the user terminal acknowledging to the sensor its receipt of the signal.
