METHOD FOR REDUCED ACCESS DELAY IN MULTIPLE ACCESS ATTEMPT EXCHANGES
First Claim
1. A method for reducing delay during a multiple access attempt exchange in a sending device with a power device, a transmit clock, and a control device;
- and a link, the method comprising steps of;
a. determining if the transmit clock is stopped;
b. if the transmit clock is stopped, activating the power device;
powering the transmit clock via the power device; and
starting the transmit clock and synchronizing the transmit clock and associated PN generators with system time;
c. sending one or more access probes from the sending device to a receiving device via the link; and
d. deactivating the power device after lapse of a predetermined time interval measured by the control device.

Abstract
A system and method for reducing access delay associated with multiple access attempt exchanges in a communications network is provided. A system of the present invention may include a mobile station and a base station system for sending and receiving signals; an air interface link for carrying the signals; and a set of timing modules for governing the transmission of the signals, whereby the set of timing modules controls activation periods of the battery'"'"'s current flow to the transmit clock according to a predetermined time interval. Control of activation periods minimizes delay during access attempts and conserves power resources.

7. A method for reducing delay during a multiple access attempt exchange in a communication network having a base station system, an air interface link, and a mobile station with a battery, a transmit clock, and a timer, the method comprising steps of:
-
a. activating the battery'"'"'s current flow to the transmit clock;
b. starting the transmit clock and synchronizing the transmit clock and associated PN generators with system time associated with the communication network via the air interface link;
c. sending a series of access probes from the mobile station to the base station system via the air interface link;
d. setting a timer for a predetermined time interval;
e. if a successive access is to be attempted, determining if the timer has expired;
f. if the timer has expired, repeating preceding steps starting from step a; and
g. if the timer has not expired, stopping the timer; and
repeating the preceding steps starting from step c. - View Dependent Claims (8, 9, 10)
