Abstract
A method for reducing frequent idle handoffs of a wireless communication device is described. A registration request is received by a base station or a femto access point from the wireless communication device. The number of registration requests received from the wireless communication device are counted while the registration timer is running. It is determined that frequent handoffs are happening when the number of registration requests received is greater than a registration threshold. A transmit power of a femto access point is adjusted if the number of registration requests received indicates that frequent handoffs are happening.

A method for reducing frequent idle handoffs of a wireless communication device, comprising:
- receiving a registration request from the wireless communication device;
- starting a registration timer;
- counting a number of registration requests received from the wireless communication device while the registration timer is running;
- determining whether the number of registration requests received is greater than a registration threshold;
- and
- adjusting a transmit power of a femto access point if the number of registration requests received is greater than the registration threshold.
A wireless device configured for reducing frequent idle handoffs of a wireless communication device, comprising:
- a processor;
- memory in electronic communication with the processor;
- instructions stored in the memory, the instructions being executable by the processor to:
- receive a registration request from the wireless communication device;
- start a registration timer;
- count a number of registration requests received from the wireless communication device while the registration timer is running;
- determine whether the number of registration requests received is greater than a registration threshold;
- and
- adjust a transmit power of the wireless device if the number of registration requests received is greater than the registration threshold.
A method for reducing frequent idle handoffs of a wireless communication device, comprising:
- sending a registration request to a femto access point;
- detecting a trigger for an idle handoff away from the femto access point;
- starting a handout timer;
- and
- determining whether a handout trigger condition is satisfied within a monitoring period after the handout timer has expired.
A wireless device configured for reducing frequent idle handoffs of the wireless device, comprising:
