Patent number: 8116769Abstract: Anchoring a communication session for a target mobile phone includes identifying a current access node operable to provide the target mobile phone access to a first network of a first network type. Potential access nodes operable to provide a mobile phone access to a second network of a second network type are identified. Whether the communication session can be handed off to a potential access node of the one or more potential access nodes is established. Anchoring of the communication session is initiated in the second network only if the communication session can be handed off to a potential access node of the one or more potential access nodes.Type: GrantFiled: February 3, 2006Date of Patent: February 14, 2012Assignee: Cisco Technology, Inc.Inventors: Steven R.

Patent number: 8116776Abstract: A method for providing telecommunication service includes transmitting a node identifier to a mobile station over a first network that supports a first communication protocol and receiving a handoff call, based on the node identifier, from the mobile station over a second network that supports a second communication protocol. The handoff call includes a mobile station identifier. The method further includes identifying a first communication link over the first network based on the mobile station identifier and initiating a second communication link with the mobile station over the second network. The method also includes terminating the first communication link.Type: GrantFiled: March 23, 2004Date of Patent: February 14, 2012Assignee: Cisco Technology, Inc.Inventors: Ramanathan T.

Patent number: 7650143Abstract: An apparatus for providing connectivity is provided that includes a mobility server operable to coordinate a communication session between a first and a second end-user device. The first end-user device is associated with a first call leg and the second end-user device is associated with a second call leg. A handoff is executed in transferring the communication session from the first end-user device to the second end-user device. In more particular embodiments, the mobility server is operable to receive signal strength information from the first end-user device and to execute the handoff based on the signal strength information. In addition, the handoff is executed based on an end-user preference that is provided in a subscription that is accessed by the mobility server.Type: GrantFiled: May 11, 2005Date of Patent: January 19, 2010Assignee: Cisco Technology, Inc.Inventors: Ramanathan T.
