METHOD AND APPARATUS FOR PERFORMING ROUTING AREA UPDATES
First Claim
7. A communication device for performing routing area updates, the communication device comprising:
- a transceiver;
a processing unit, communicatively coupled to the transceiver,adapted to determine at least one ofwhether a remote unit is within an edge portion of a routing area orwhether the remote unit is within an end portion of a routing area update interval,adapted to determine whether at least one condition is present for the remote unit to perform a resource-efficient routing area update, andadapted to perform a routing area update, via the transceiver, when the at least one condition is present and when at least one ofthe remote unit is determined to be within the edge portion orthe remote unit is determined to be within the end portion.

Abstract
Various embodiments are described for potentially reducing the impact of routing area updates on wireless system capacity. Logic flow diagram 10, in FIG. 1, depicts such functionality. In some embodiments, it is determined (12) whether a remote unit is within an edge portion of a routing area, while in other embodiments it is determined (12) whether the remote unit is within an end portion of a routing area update interval. It is also determined (14) whether one or more conditions are present for the remote unit to perform a resource-efficient routing update. A routing area update is then performed (16) when one or more of the conditions are present and when, depending on the embodiment, either the remote unit is determined to be within the edge portion of the routing area or the remote unit is determined to be within the end portion of the routing area update interval.

11-1. The communication device of claim 10, wherein at least one of an increased threshold signal strength value or an increased threshold number of signal strength bars is used when at least one secondary condition is present, wherein the at least one secondary condition comprises at least one of
the remote unit is moving at a below-threshold velocity, a paging interval for the remote unit has a below-threshold period, the remote unit has only moved a below-threshold distance within the edge portion of the routing area, or a greater signal strength is anticipated for the remote unit while within the edge portion of the routing area.
