Seamless mobility in wireless networks
First Claim
1. A computer-implemented method in a system coordinator on a wireless communication network and in communication with a plurality of access points, the method comprising the steps of:
- connecting with the plurality of access points for management through a set of communication links between the plurality of access points and the system coordinator, wherein the plurality of access points send a customized beacon message to be received by a particular wireless device with communication parameters selected by the system coordinator for the particular wireless device to force the particular wireless device into compliance, by selecting from the communication parameters provided by the system coordinator although a communication protocol indicates that the wireless device chooses communication parameters;
coordinating connections with wireless devices desiring contact with that communication network through the plurality of access points, wherein the plurality of access points on the wireless network appear to be identical to the wireless devices; and
conducting a soft handoff to a particular access point of the plurality of access points from a second access point of the plurality of access points by the system coordinator, wherein in response to the soft handoff, the particular access point maintains an identifier for the particular wireless device, the identifier being previously maintained at the second access point that disassociates with the particular wireless device responsive to the soft handoff, wherein the soft handoff is transparent to the particular wireless device,wherein the particular access points associates with the particular wireless device by responding to a message sent by the particular wireless device without any type of configuration by the particular wireless device.

Abstract
AP'"'"'s associated with a communication network and any wireless devices desiring contact, operated according to a protocol in which each wireless device selects AP'"'"'s with which to communicate. A system coordinator causes the AP'"'"'s to operate so as to guide each wireless device to an AP selected by the system coordinator. This has the effect that, notwithstanding that the protocol involves having the wireless device make the selection of AP, functionally, the AP'"'"'s make the selection for it. In a 1st technique, multiple AP'"'"'s share an identifier, with the system coordinator directing one particular AP to respond to the wireless device, thus appearing to wireless devices as a “personal cell”. In a 2nd technique, AP'"'"'s each maintain identifiers substantially unique to each wireless device, with the system coordinator directing only one particular AP to maintain any particular wireless device'"'"'s identifier, thus appearing to wireless devices as a “personal AP”.

7. A non-transitory computer readable medium storing a computer program product to perform a method in a system coordinator on a wireless communication network and in communication with a plurality of access points, the method comprising the steps of:
-
connecting with the plurality of access points for management through a set of communication links between the plurality of access points and the system coordinator, wherein the plurality of access points send a customized beacon message to be received by a particular wireless device with communication parameters selected by the system coordinator for the particular wireless device to force the particular wireless device into compliance, by selecting from the communication parameters provided by the system coordinator although a communication protocol indicates that the wireless device chooses communication parameters; coordinating connections with wireless devices desiring contact with that communication network through the plurality of access points, wherein the plurality of access points on the wireless network appear to be identical to the wireless devices; and conducting a soft handoff to a particular access point of the plurality of access points from a second access point of the plurality of access points by the system coordinator, wherein in response to the soft handoff, the particular access point maintains an identifier for the particular wireless device, the identifier being previously maintained at the second access point that disassociates with the particular wireless device responsive to the soft handoff, wherein the soft handoff is transparent to the particular wireless device, wherein the particular access points associates with the particular wireless device by responding to a message sent by the particular wireless device without any type of configuration by the particular wireless device.
