Abstract
A detecting base station comprises a device beacon detector that is configured to apply wireless wide area network (WWAN) system timing to receive a device beacon transmitted by a wireless communication device in accordance with the WWAN system timing and outside of a WWAN uplink channel. The detecting base station may include a wireless wide area network (WWAN) interface configured to receive the WWAN system timing from the WWAN.
Claims18
A transceiver node comprising:
- a device beacon detector configured to apply wireless wide area network (WWAN) system timing to receive a device beacon transmitted by a wireless communication device in accordance with the WWAN system timing and outside of a WWAN uplink channel;
- and
- a transmitter configured to transmit a device proximity message to the WWAN that invokes transmission of a search message to the wireless communication device instructing the wireless communication device to adjust a searching scheme for searching for the transceiver node.
A femtocell base station comprising:
- a wireless wide area network (WWAN) interface configured to receive WWAN system timing from a WWAN;
- a device beacon detector configured to detect a device beacon transmitted from a wireless communication device receiving the WWAN system timing information from the WWAN and transmitting the device beacon in accordance with the WWAN system timing information and outside a WWAN uplink frequency band;
- and
- a transmitter configured to transmit signals, wherein the WWAN interface is further configured to transmit a device proximity message to the WWAN that invokes transmission of a search message to the wireless communication device instructing the wireless communication device to adjust a searching scheme for searching for the femtocell base station to increase a likelihood of detecting the signals.
