May 2003 doc.: IEEE 802.11-03/xxxr0 May 2003 Background A multi-access capable terminal located within the coverage area of e.g. several 802.11 APs and WWAN base stations, must decide which network to associate with For a terminal associated to the WLAN, but makes frequent handovers between the APs, it might be a good idea to change to the WWAN The process of selecting may be located within the network, within the terminal or in both, as a cooperation between the network and the terminal. Falk and Jevinger, TeliaSonera Falk and Jevinger, TeliaSonera

May 2003 Proposal Add a counter (RoamingCount) that keeps track on the number of handovers done within a certain time period (RoamingCountPeriod) The RoamingCount parameters should be available both in the terminal and on the network side For details, see 11-03-305r0 Falk and Jevinger, TeliaSonera
