Abstract
Methods and systems for cellular device detection are presented. A signal processing receiver operable to determine a plurality of uplink parameters according to a downlink broadcast message. The signal processing receiver is also configurable to receive an uplink message according to the plurality of uplink parameters, thereby determining a presence and/or an identity of a cellular device by decoding the uplink message.
Claims15
A method for detecting a cellular device with a signal processing receiver, the method comprising:
- determining a plurality of uplink parameters based on a downlink broadcast message;
- configuring the signal processing receiver to receive an uplink message according to the plurality of uplink parameters, wherein the uplink message is transmitted by a cellular device in response to the downlink broadcast message;
- and
- detecting the cellular device by processing the uplink message.
1 more element
A system comprising:
- a signal processing receiver operable to determine an uplink band based on a downlink broadcast message, the signal processing receiver being operable to determine that a cellular device is active based on an uplink message in the uplink band, wherein the uplink message is transmitted by the cellular device in response to the downlink broadcast message;
- and
- a memory operable to store the uplink band.
