Abstract
A method for determining the presence of a femtocell in a network includes capturing a baseline sample for the network. The baseline sample includes a plurality of measurements taken across a plurality of downlink radio frequency (RF) bands within the network. The network is monitored to identify an RF signal having a signal strength value exceeding a predetermined threshold. The identified RF signal is compared with the captured baseline sample. The presence of the femtocell in the network is determined based on a determination that the identified RF signal does not match any of the plurality of measurements contained within the baseline sample.
Claims20
A method for determining the presence of a femtocell in a network, the method comprising the steps of:
- capturing a baseline sample for the network, wherein the baseline sample comprises a plurality of measurements taken across a plurality of downlink radio frequency (RF) bands within the network;
- monitoring the network to identify an RF signal;
- determining if the identified RF signal has a signal strength value exceeding a predetermined threshold;
- determining that the baseline sample does not include the identified RF signal having a signal strength value exceeding the predetermined threshold;
- and
- determining the presence of a said femtocell in the network when the baseline sample does not include the identified RF signal exceeding the predetermined threshold.
A apparatus to determine the presence of a femtocell in a network, comprising:
- a memory;
- a processor disposed in communication with said memory, and configured to issue a plurality of instructions stored in the memory, wherein the instructions cause the processor to:
- capture a baseline sample for the network, wherein the baseline sample comprises a plurality of measurements taken across a plurality of downlink radio frequency (RF) bands within the network;
- monitor the network to identify an RF signal;
- determine if the identified RF signal has a signal strength value exceeding a predetermined threshold;
- determine that the baseline sample does not include the identified RF signal having a signal strength value exceeding the predetermined threshold;
- and
- determine the presence of a said femtocell in the network when the baseline sample does not include the identified RF signal exceeding the predetermined threshold.
A non-transitory computer readable storage medium and one or more computer programs embedded therein, the computer programs comprising instructions, which when executed by a computer system, cause the computer system to:
- capture a baseline sample for the network, wherein the baseline sample comprises a plurality of measurements taken across a plurality of downlink radio frequency (RF) bands within the network;
- monitor the network to identify an RF signal;
- determine if the identified RF signal has a signal strength value exceeding a predetermined threshold;
- determine that the baseline sample does not include the identified RF signal having a signal strength value exceeding the predetermined threshold;
- and
- determine the presence of a said femtocell in the network when the baseline sample does not include the identified RF signal exceeding the predetermined threshold.
