 Hold mode to the Active mode may be indicated by a BTS transmission of power control signals to the terminal during a fixed period of time recognized by the terminal. Previous attempts to provide power control signals during this transmission period have generally been limited to the BTS transmitting a fixed value to the terminal, and the terminal transmitting at a predetermined power level independent of the signal to noise ratio or the distance from the terminal to the BTS. This arrangement results in an inaccurate power level transmission at the beginning of the Active mode, typically resulting in lower link quality, interference to other terminals on the reverse link, or both. An excessively high power level transmitted by the terminal upon entering the Active mode then requires dynamic correction in the Active mode, which requires system processing, provides poor traffic quality, and is generally undesirable. On the other hand, an excessively low power level transmitted by the terminal upon entering the Active mode causes low link quality and also requires dynamic correction in the Active mode, both of which are generally undesirable. The previous power control transition scheme thus produced improper results, interference, and created certain delays before a condition appropriate power level was made available between the terminal and the BTS.
A further power control problem can occur when the terminal and BTS interact in the presence of interference or inefficient signal transmission conditions. For example, the terminal may transmit during periods when the BTS is assessing signal strength, and the BTS may not receive the terminal transmission for various reasons. Failure to receive a signal from the terminal can cause the BTS to transmit commands to the terminal to increase power. Such transmission inefficiency can further increase the possibility of incorrect power control commands transmitted from the BTS to the terminal and result in further delay before an adequate signal is available.
Furthermore, other CDMA systems, such as those currently available, transition between different states and have similar limitations in establishing effective power control feedback and sufficient Active mode quality. For example, a BTS in a previously known CDMA communication system can request that a terminal transition from the Idle state to the Active state, a process sometimes referred to as traffic channel initialization. Once the BTS notifies the terminal of the forward link channel, the terminal attempts to acquire the signal from the BTS. The signal acquired from the BTS by the terminal may comprise the power control signal, or a combination of the power control signal and other forms of signals. In this arrangement, as in cdma2000, slow acquisition of the BTS signal by the terminal, as well as a delayed start of effective power control operation
Hold mode to the Active mode may be indicated by a BTS transmittance of exponent control signals to the terminal during a fasten period of time accredit by the terminal. Previous attempt to provide power command signals during this transmission menstruation have by and large been limited to the BTS transmitting a fixed value to the terminal, and the terminal convey at a predetermined power level autonomous of the signal to noise ratio or the distance from the end to the BTS. This arrangement leave in an inaccurate power horizontal surface transmission at the beginning of the Active mode, typically resulting in low link quality, interference to other terminals on the reverse liaison, or both. An excessively high power level transmitted by the terminal upon entering the Active mode then requires dynamic correction in the Active manner, which requires system processing, provide poor traffic quality, and is generally undesirable. On the early hand, an excessively abject power level air by the terminal upon entering the Active mode causes low link quality and also requires dynamic correction in the Active mood, both of which are generally undesirable. The former ability control transition scheme thus produced improper results, interference, and created sealed delays before a circumstance appropriate power level was made available between the terminal and the BTS. 
 A further power dominance problem can occur when the end and BTS interact in the presence of interference or inefficient signal transmission condition. For example, the end may transmit during periods when the BTS is assessing signal strength, and the BTS may not receive the concluding transmission for various reasons. bankruptcy to receive a signal from the terminal can cause the BTS to transmit command to the terminal to increase power. Such transmission inefficiency can farther increase the possibility of incorrect power control commands transmitted from the BTS to the end and result in further delay before an adequate signal is available. 
 Furthermore, other CDMA systems, such as those currently available, transition between different states and have exchangeable limitation in establishing effective power control feedback and sufficient Active mode quality. For example, a BTS in a previously know CDMA communication system can request that a terminal transition from the dead state to the Active state, a process sometimes referred to as traffic groove initialization. Once the BTS notifies the terminal of the forward link channel, the terminal attempts to acquire the signal from the BTS. The signal get from the BTS by the terminal may comprise the power control signal, or a combination of the power control signal and early shape of signals. In this arrangement, as in cdma2000, slow acquisition of the BTS signal by the terminal, as well as a delayed start of effective power control mathematical process
