Abstract
An improved technique for reducing unnecessary routing area updates ensures that the location of a mobile terminal is known when the mobile terminal starts data communication after being in a standby state. If no packet transmission is taking place when a mobile terminal moves between the first and second wireless access systems in a common routing area of a packet radio access network no routing area update takes place. If packet transmission is initiated no routing area update may be required if the mobile is connected to the same wireless access system as in its previous packet transmission. If packet transmission is initiated a routing area update may take place if the mobile is connected to a different wireless access system than in the previous packet transmission. If packet transmission is initiated by the mobile the packet transmission initiation may include the routing area update.
