Abstract
A mobility management node and a method in a mobility management node for reducing signalling caused by changes of location of a radio terminal, which mobility management node is configured to be operatively comprised by a wireless communication system and to operatively manage the mobility of the radio terminal and to operatively communicate with a gateway node acting as an interface between the system and an external network. The method comprises obtaining initial position information; obtaining boundary information indicating a boundary area wherein at least one of a policy or a charging rule is to be applied for the radio terminal; obtaining current position information; determining whether the radio terminal is inside or outside the boundary area; providing mobility information when the radio terminal is outside the boundary area and not providing mobility information to the gateway node when the radio terminal is inside the boundary area.
