<p>A mobile node receives cell-site transmitted signals and determines their channel quality while establishing a unicast packet session, and transmits a report to the current cell-site if there is at least one neighbor cell-site detected whose channel quality is higher than that of the current cell-site for informing the identifier and channel quality of the detected cell-site, and requesting the resource necessary to support the session. In one embodiment, the current cell-site selects candidate cell-sites based on the report and informs the mobile node of the selected cell-sites. The mobile node selects a new cell-site from the candidate cell-sites and informs the current cell-site of the new cell-site. The requested resource is then reserved in the new cell-site and an IP address and at least one channel identifier are assigned. The mobile node uses the channel identifier to establish a wireless link of the reserved resource to the new cell-site and the IP address to reestablish the session. <IMAGE></p> |
