Methods, apparatuses and systems directed to a border access point protocol that facilitates network selection and mobility operations for wireless clients, such as dual-mode wireless telephones and other devices. In one implementation, the present invention provides a wireless network infrastructure comprising a plurality of access points, at least some of which are so-called border access points that provide border information to wireless clients. The border information, in one embodiment, indicates to the wireless client that the transmitting access point is proximal to the perimeter of the intended coverage area of the wireless network infrastructure. In another implementation, the border information indicates that the transmitting access point is proximal to a point of egress from, or ingress to, a coverage area. Wireless clients within range of the border access points can use the border information to facilitate or enhance selection of a network for initiation of a given section, as well as in handoff or other mobility operations between two network types or domains (e.g., a WLAN and a cellular network). |
