System(s) and method(s) are provided for signaling-triggered power adjustment in a femto cell. Attachment signal activity is measured and a set of derived signaling activity metrics are assessed and compared with a set of thresholds. An activity metric that overcomes an associated threshold results in a power adjustment of the transmission power of a femto access point (AP). By monitoring LAU (location area update), RAU (routing area update), and call activity, signaling activity metrics (e.g., signaling failure rate, access control rejection rate, or dwell time) are determined and a femto AP can optimize transmission power to ensure coverage maintenance and confinement, as well as mitigate unnecessary signaling. Alarm(s) can be conveyed to a femto network platform when power increases after an adjustment cycle; alarm(s) can prompt a network-based response to actively address femto cell operation. Signaling-triggered power management affects operation of AP serving the femto cell and served mobile terminals. |
