Power control for handoffs between voice over internet protocol and circuit switched calls

摘要

An open loop power control method for setting a transmit power of mobile station ( 22 ) during a handoff from a voice over Internet protocol (VoIP) service to a circuit switched service sets a transmit power of the mobile station based upon a power level associated with the VoIP call. A disclosed example includes using an average power level of a reverse pilot channel of the VoIP call and correction factors based upon forward link and reverse link parameters during the VoIP call.
