Patent number: 7907564Abstract: A method includes identifying a plurality of communication channels at a wireless device and classifying each of the communication channels into one of a plurality of groups. The method also includes scanning the communication channels in the groups. The communication channels in at least one of the groups are scanned at a different frequency than the communication channels in at least one other of the groups. In addition, the method includes updating one or more of the groups based on the scans.Type: GrantFiled: November 12, 2002Date of Patent: March 15, 2011Assignee: Cisco Technology, Inc.Inventors: Carlos V. Laux, Kamaldip Toor, Marcio G. de Siqueira, Sudhakar S. Valluru, Steven Hayashi

Patent number: 7840185Abstract: A system includes an enterprise network having a call control system that manages telephony services for wireless handsets. At a remote site, a computing device establishes a secure, wireline communication session with the enterprise network. The computing device also establishes wireless, packet-based links with one or more handsets. The device acts as a relay to enable the handsets to receive telephony services managed by the enterprise network even though outside of the service area of the enterprise network.Type: GrantFiled: February 18, 2008Date of Patent: November 23, 2010Assignee: Cisco Technology, Inc.Inventors: Kamaldip Toor, Steven Hayashi, Carlos V. Laux, Marcio Guidorizzi de Siqueira, Sudhakar Srinivasa Valluru

Patent number: 7783284Abstract: A method for site administration includes receiving a user's instruction to invoke a tool at a wireless handset. The method also includes invoking execution of the tool at the wireless handset. The tool is operable to identify at least one characteristic of at least one access point in a communication system and to display the at least one characteristic associated with the at least one access point to the user at the handset.Type: GrantFiled: November 12, 2002Date of Patent: August 24, 2010Assignee: Cisco Technology, Inc.Inventors: Carlos V. Laux, Kamaldip Toor, Marcio G. de Siqueira, Sudhakar S. Valluru, Steven Hayashi

Patent number: 7227853Abstract: A method is provided that includes receiving a request from a communication device to establish a communication session with a mobile station, the mobile station being operable to roam between a private and a public network. The mobile station is signaled via a cellular data network that a call is being initiated for the mobile station. Signaling information may be exchanged with a voice gateway such that one or more voice circuits are established. A signaling pathway may be established between an Internet protocol private branch exchange (IP PBX) and the mobile station via the cellular data network. The establishment of the signaling pathway is substantially concurrent with the establishment of one or more of the voice circuits. One or more features associated with a private network are delivered to the mobile station during the communication session as an end user moves between the public and private networks.Type: GrantFiled: June 16, 2006Date of Patent: June 5, 2007Assignee: Cisco Technology, Inc.Inventors: Ramanathan T. Jagadeesan, Bich T. Nguyen, Kamaldip Toor, Sudhakar S. Valluru, Christopher E. Pearce

Publication number: 20070124478Abstract: Providing probe signals from a node includes receiving at the node an instruction to send the probe signals over channels, where the instruction comprises probe parameter values describing deployment of the probe signals. The node sends the probe signals to a controller through access points. Each access point is associated with one or more channels. The controller is operable to assign an access point to the node in accordance with an analysis of the probe signals.Type: ApplicationFiled: November 28, 2005Publication date: May 31, 2007Inventors: Hisham Abdelhamid, Carlos Laux, Marcio de Siqueira, Jennifer Walker, Kamaldip Toor

Publication number: 20070091839Abstract: Identifying one or more access points in one or more channels to facilitate communication includes identifying an access point in a channel in a first channel band of a first frequency range to facilitate communication with a network. The first channel band includes a plurality of channels and the first frequency range includes a plurality of channel bands. The identified access point is used to communicate with the network. A scanning sequence is initiated in the first frequency range and a second frequency range to identify one or more access points in one or more channels to facilitate communication. The second frequency range includes a plurality of channel bands.Type: ApplicationFiled: October 25, 2005Publication date: April 26, 2007Inventors: Hisham Abdelhamid, Carlos Laux, Marcio Siqueira, Jennifer Walker, Kamaldip Toor

Patent number: 7076251Abstract: A method is provided that includes receiving a request from a communication device to establish a communication session with a mobile station. The request is responded to by signaling the mobile station via a cellular data network that a call is being initiated for the mobile station. Signaling information may be exchanged with a voice gateway such that one or more voice circuits are established to accommodate voice data that may propagate between the communication device and the mobile station. A signaling pathway may be established between an Internet protocol private branch exchange (IP PBX) and the mobile station via the cellular data network. The establishment of the signaling pathway is substantially concurrent with the establishment of one or more of the voice circuits such that one or more features associated with a private network are delivered to the mobile station during the communication session.Type: GrantFiled: September 11, 2003Date of Patent: July 11, 2006Assignee: Cisco Technology, Inc.Inventors: Ramanathan T.
