Abstract
The power control process switches between IS-95 forward power control and fast forward power control using either speed or hand-off status information from the mobile radiotelephone. If the received information indicates either a slower speed or the number of communication links is less than a predetermined number, the fast forward power control process is used. If the received information indicates either a fast speed or the number of links is greater than or equal to the predetermined number (the radiotelephone is in a hand-off situation), the forward power control process is used.
Claims5
A method for switching between forward power control and fast forward power control in a radiotelephone system comprising a plurality of base stations communicating with a radiotelephone, the method comprising the steps of:
- receiving speed information from the radiotelephone;
- if the speed information is above a predetermined threshold, using the forward power control;
- and
- if the speed information is below the predetermined threshold, using the fast forward power control.
A method for switching between forward power control and fast forward power control in a radiotelephone system comprising a plurality of base stations communicating with a radiotelephone over communication links, the method comprising the steps of:
- monitoring a hand-off status of the radiotelephone;
- if the hand-off status indicates that the number of communication links is greater than or equal to a predetermined threshold, using the forward power control;
- and
- if the hand-off status indicates that the number of communication links is less than the predetermined threshold, using the fast forward power control.
A method for switching between a forward power control process and a fast forward power control process in a radiotelephone system comprising a plurality of base stations communicating with a radiotelephone, the method comprising the steps of:
- receiving information from the radiotelephone;
- if the received information is hand-off status indicating that the number of communication links is greater than or equal to a predetermined threshold, using the forward power control;
- if the received information is location information indicating that the number of communication links is less than the predetermined threshold, using the fast forward power control;
- if the received information is speed information indicating a speed greater than a predetermined speed threshold, using the forward power control process;
- and
- if the received information is speed information indicating a speed less than the predetermined speed threshold, using the fast forward power control process.
