Abstract
A method and apparatus for managing paging related delays between a mobile station and a base station is provided, which includes the use of a fractional slot cycle index. A first value for the slot cycle index, which is equal to an integer value less than a desired fractional slot cycle index value, is selected for use during a period of time corresponding to a determined proportion of a reduced slot cycle period, and a second value for the slot cycle index, which is equal to an integer value greater than a desired fractional slot cycle index value, is selected for use during a period of time corresponding to a remaining portion of the reduced slot cycle period.
Claims21
A method of managing paging related delays between a mobile station and a base station, said method comprising:
- setting a slot cycle index to a first value, which is equal to an integer value less than a desired fractional slot cycle index value;
- operating in slotted mode for receiving paging messages using the first value of the slot cycle index for a determined proportion of a reduced slot cycle period;
- setting a slot cycle index to a second value, which is equal to an integer value greater than the desired fractional slot cycle index value;
- and
- operating in slotted mode for receiving paging messages using the second value of the slot cycle index for a remaining portion of the reduced slot cycle period.
A mobile station comprising:
- a slotted mode receiver for receiving a paging signal, the slotted mode receiver having a slot cycle index corresponding to the periods during which the receiver is activated and paging signals can be received;
- and
- a controller, coupled to the slotted mode receiver, wherein the controller is adapted for setting the slot cycle index to a first value, which is equal to an integer value less than a desired fractional slot cycle index value during a period of time corresponding to a determined proportion of a reduced slot cycle period, and is adapted for setting the slot cycle index to a second value, which is equal to an integer value greater than a desired fractional slot cycle index value during a period of time corresponding to a remaining portion of the reduced slot cycle period.
A base station comprising:
- a transmitter for transmitting a paging signal;
- and
- a controller including a scheduler, which is adapted for scheduling the transmission of a paging signal in a paging slot, responsive to a fractional slot cycle index value and any paging signal offset value associated with an intended mobile station recipient;
- wherein the fractional slot cycle index includes a slot cycle index having a first integer value, which is less than the fractional slot cycle index value, during a period of time corresponding to a determined proportion of a reduced slot cycle period, and a second integer value, which is greater than the fractional slot cycle index value, during a period of time corresponding to a remaining portion of the reduced slot cycle period.
