Method and Apparatus For Reducing Latency During Wireless Connectivity Changes
First Claim
1. A method comprising:
- detecting indicia of a change in wireless connectivity of a mobile station with respect to a first wireless access point and a second wireless access point, wherein the first wireless access point and the second wireless access point share a common subnet;
automatically effecting at least one of;
at least one communication between the first and second wireless access point regarding the change in wireless connectivity; and
establishment of a temporary data tunnel as between the first and second wireless access point; and
automatically establishing a data flow path for the mobile station as between the second wireless access point and a network element that is hierarchically differentiated from the second wireless access point comprising, at least in part, automatically sending a registration request from the second wireless access point to the network element other than in response to a specific request from the mobile station to send the registration request.

Abstract
A wireless access point (102) detects an indicia of a change in wireless connectivity of a mobile station (101) with respect to itself and another wireless access point (103). The wireless access point then automatically effects at least one of establishing a communication between itself and the second wireless access point regarding the change in wireless connectivity and/or establishing a temporary data tunnel as between itself and the second wireless access point. These network elements can also act to automatically establish a data flow path for the mobile station as between the second wireless access point and a network element (such as a mobility management agent (105)) that is external to the common subnet. In a preferred approach this comprises, at least in part, automatically sending a registration request to the network element other than in response to a specific request from the mobile station to send such a registration request.

18. A wireless access point for use in a communication network comprising a local subnet that comprises a plurality of wireless access points, the wireless access point comprising:
-
a change in wireless connectivity detector responsive to indicia of a change in wireless connectivity of a mobile station with respect to a second wireless access point, wherein the second wireless access point comprises a part of the local subnet; a data flow path establishment unit that is responsive to the change in wireless connectivity detector wherein the data flow establishment unit is configured and arranged to automatically establish a data flow path for mobile station data as between the wireless access point and the second wireless access point; a registration request module; and a transmitter operably coupled to the registration request and being configured and arranged to transmit the registration request to a network element that is external to the local subnet other than in response to a specific request from the mobile station to send the registration request. - View Dependent Claims (19, 20)
