A METHOD OF OPERATING A RADIO ACCESS NETWORK WITH MULTIPLE RADIO ACCESS TECHNOLOGIES

摘要

In a cellular radio system supporting a multitude of radio access technologies, knowledge of the coverage of different standards is collected in and signaled to a mobile station when it is within reach for a particular standard. Hereby the mobile station can save a lot of battery. Hence, the network is set to adaptively learn about the coverage of different standards such as Wireless Local Area Networks (WLAN) coverage and aid mobile in the task of monitoring the area where it is currently located, thereby saving a lot of power for the mobile station.
