System and methods for generating and transmitting dynamic route-update-radius parameters are described. The parameters are dynamic in that the parameters may be modified from time-to-time. Modification of the parameters may be triggered by a radio access network (RAN) determining that a coverage area formed by the RAN is handling more than a threshold amount of communications to and/or from access terminals operating in the coverage area. The RAN may transmit the dynamic route-update-radius parameters so as to prevent some access terminals from registering with the coverage area while the coverage area is handling more than the threshold amount of communications. While the coverage area is handling a reduced amount of communications, such as less than a threshold amount of communications, the access network may transmit default route-update-radius parameters to coverage areas remote from that coverage area. The route-update-radius parameters may include a route-update-radius, a modified route-update-radius, and a route-update-radius offset.
