Abstract
Methods and apparatus for use in switching communication operations between a wireless local area network (WLAN) (e.g. an IEEE 802.11-based network) and a wireless wide area network (WWAN) (e.g. a cellular telecommunications network) for a mobile communication device are disclosed. A network support node which is utilized to facilitate such transitioning has a first communication interface (e.g. an Ethernet interface) for connection with a communication network which includes the WLAN and a second communication interface (e.g. a cellular radio air interface) for communicating with a base station of the WWAN over a wireless communication link.
