Abstract
The present invention relates to the coordination of simultaneous multi-RAT camping in a wireless communication network that provides radio access for a terminal device via at least a first and second wireless radio access operating with different radio access technologies. The improved multi-RAT camping is achieved by transmitting, by a network node, an indication regarding a set of camping areas, CAs, including a first set of camping areas being associated with the first RAT and a second set of camping areas being associated with the second RAT; performing, by the terminal device, camping in a coverage area defined based on the set of CAs; and updating, by the terminal device, the communication network with a geographic location of the terminal device a) when the terminal device enters a new coverage area being different from the coverage area defined by both the first and second set of CAs as a first mechanism, or b) when the terminal device enters a new coverage area being different from the coverage area defined by one of the first and second set of CAs as a second mechanism.
