Title: Method for source allocation between sector in BTS handoff zone of CDMA mobile communication system
Inventor: KIM SEONG SU
IPC: H04B7/26
Filed: 2002-05-31
Abstract: PURPOSE: A method for assigning resources between sectors in a base station handoff region of a CDMA mobile communication system is provided to reject a call add request when a changing rate for specific time is less than a mobile index, and to permit the request if the changing rate is more than the mobile index, thereby efficiently using resources. CONSTITUTION: When a message is received from a terminal(ST11), a base station call processing block decides the message(ST12). If the received message is not a soft add message, the block decides whether the message is a power request message(ST15). If so, the block stores a received power level value as a response for the message(ST16). The block counts reception of the power request message(ST17), and checks the number of counted values(ST18). If the counted number is bigger than a counted number per unit time, the block re-requests the terminal to measure the power level value, and if the counted number is smaller, the block measures a time changing rate for received power level values(ST19). The block compares the measured power time changing rate with a mobile index(ST20). If the changing rate is bigger, the block permits a soft add process(ST21).

Title: Slot cycle assignment within a communication system
Inventor: CROCKER RONALD THOMAS
IPC: H04L29/08
Filed: 2002-06-14
Abstract: PURPOSE: A slot cycle assignment within a communication system is provided to reduce a time necessary for making a dispatch call quickly. CONSTITUTION: MUs(Mobile Units)(303,305,307) operating in a dispatch mode receive the first slot cycle. MUs(302,304,306,308) not operating in the dispatch mode receive the second slot cycle. The second slot cycle is greater than the first slot cycle, so that the MUs(303,305,307) operate in the dispatch mode "wake up" during a slot cycle normally utilized for interconnect calls. Because shorter slot cycles are utilized for the MUs(303,305,307) operating in the dispatch mode, a time required for making a dispatch call is greatly reduced.
