Patent number: 9357586Abstract: In a communication network (400), wireless access points (300) utilize one or more agents (302, 306) to support the operating needs of corresponding mobile stations. Pursuant to one approach, the agent supports translation of the mobile station's end-to-end protocol-based messages to Internet Protocol-based messages that are readily ported through an Internet Protocol-friendly communication system infrastructure that preferably eschews the use of network elements that rely upon unique and/or proprietary non-Internet Protocol interfaces. Pursuant to another approach the wireless access point is able to interact on a peer-to-peer basis with other wireless access points in order to facilitate, for example, handovers and other mobility management tasks.Type: GrantFiled: June 19, 2006Date of Patent: May 31, 2016Assignee: Google Technology Holdings LLCInventors: Anand S. Bedekar, Rajeev Agrawal, Venkat Gopikanth, Suresh Kalyanasundaram, Vishnu Ram Ov

Patent number: 9344934Abstract: 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.Type: GrantFiled: June 19, 2006Date of Patent: May 17, 2016Assignee: Google Technology Holdings LLCInventors: Anand S.

Patent number: 9031047Abstract: A wireless access point (300A, 300B, 300C) provides (101) a surrogate Internet Protocol address to use on behalf of a mobile station (401). That wireless access point then uses (102) that surrogate Internet Protocol address along with its own Internet Protocol address to facilitate establishing one or more data tunnels as necessary to support the communication needs of the mobile station.Type: GrantFiled: June 19, 2006Date of Patent: May 12, 2015Assignee: Google Technology Holdings LLCInventors: Anand S. Bedekar, Rajeev Agrawal, Venkat Gopikanth, Suresh Kalyanasundaram, Vishnu Ram Ov

Patent number: 9026152Abstract: Mobile station information is exchanged between a plurality of distributed mobility agents (106, 108). The exchange is initiated by a mobility agent (106) associated with a last known network access point (110) that has communicated with the mobile station (114). The mobile station (114) is paged from at least one network access point using an available air interface technology to interface with the mobile station (114) and using the mobile station information. No centralized controller is used in the paging.Type: GrantFiled: June 19, 2006Date of Patent: May 5, 2015Assignee: Google Technology Holdings LLCInventors: Anand S. Bedekar, Rajeev Agrawal, Venkat Gopikanth, Suresh Kalyanasundaram, Vishnu Ram Ov

Patent number: 8195807Abstract: An indication is received from the mobile station (114) indicating that the mobile station (114) is moving from an originating mobility agent (106) to a destination mobility agent (108). An identity of the destination mobility agent (108) is determined using the indication. Routing information is sent from the originating mobility agent (106) to the destination mobility agent (108) using the identity. Incoming data is routed to the mobile station (114) using the routing information.Type: GrantFiled: June 19, 2006Date of Patent: June 5, 2012Assignee: Motorola Mobility, Inc.Inventors: Anand S. Bedekar, Rajeev Agrawal, Venkat Gopikanth, Suresh Kalyanasundaram, Vishnu Ram Ov

Patent number: 8160067Abstract: A wireless access point (200), upon determining (101) that a need exists to support a communication need of a mobile station, acquires (102) a first Internet Protocol (IP) address and automatically transmits (103) a gratuitous Address Resolution Protocol message to a local router to thereby cause the latter to correlate the first IP address to a Medium Access Control address for the wireless access point. In a preferred embodiment the wireless access point can also automatically transmit a registration request to a remote network element (such as a Home Agent) that presents this first IP address as a care-of address to use in conjunction with another IP address that serves as a home address for the mobile station.Type: GrantFiled: June 19, 2006Date of Patent: April 17, 2012Assignee: Motorola Mobility, Inc.Inventors: Anand S. Bedekar, Rajeev Agrawal, Venkat Gopikanth, Suresh Kalyanasundaram, Vishnu Ram Ov

Patent number: 8144687Abstract: In the present technique of a communication system (100), an address of a forwarding agent (114) linked to a receiver node (112) is detected to provide a discovered address. The discovered address is then used to establish a direct route with the forwarding agent of the receiver node for subsequent communications between a sender node (104) and the receiver node.Type: GrantFiled: June 19, 2006Date of Patent: March 27, 2012Assignee: Motorola Mobility, Inc.Inventors: Anand S.

Publication number: 20080294891Abstract: A method for authenticating a mobile node (102) in a communication network (100) is provided. The communication network includes at least one proxy server and a home server. The mobile node and the home server include a shared key. The shared key uniquely associates the mobile node with the home server. The method at the mobile node includes sending (204) a request for an Internet Protocol (IP) address to at least one proxy server. Further, the method includes receiving (206) a nonce in response to the request, from a proxy server of the at least one proxy server. The method also includes deriving (208) a session key, based on the nonce and the shared key. The session key authenticates the mobile node to initiate a secure communication session with the proxy server.Type: ApplicationFiled: August 7, 2008Publication date: November 27, 2008Applicant: MOTOROLA, INC.Inventors: Vishnu Ram OV, Vihang G.
