Abstract

In a multi-access communication system, a terminal is kept reachable through a first access network, which is most resource efficient one of the available access networks for keeping the terminal reachable. The terminal scans passively for the existence of usable base stations for other access networks of the system and reports data associated with such existences to the first access network. When a request for a call to the terminal is received, a paging is performed in the first access network. The paging message comprises information about preferred access network, based on the reported data of the existence of usable base stations or access points of other access networks. The terminal connects to the preferred access network and performs a call set-up directly in the preferred access network.
