Abstract:
1. A network architecture, comprising: a connection origination exchange (COX); a first proxy controller coupled to the COX; a first access point coupled to the first proxy controller; and a mobile node wirelessly coupled to the first access point, wherein the mobile node communicates with a terminating node of a network through the first access point and the first proxy controller using an identification maintained by the first proxy controller, wherein the COX originates a connection with the terminating node on behalf of the mobile node using the identification provided by the first proxy controller, wherein connection services are provided via a first connection segment between the mobile node and the COX at a first time and are provided via a second connection segment between the mobile node and the COX at a second time, wherein, when the mobile node moves out a coverage area of the first access point into a coverage area of a cellular network, the first proxy controller identifies the first access point as an egress access point, sends a data ping signal to the mobile node through the cellular network to locate the mobile node, and adds a participant to the connectivity maintained by the COX between the mobile node and the terminating node; wherein, after receiving a message from the first proxy server for adding the participant, the COX provides a multi-party conference connection between the mobile node and the terminating node to simultaneously communicate with the terminating node via the first access point and the cellular network; and wherein, when the mobile node becomes temporarily unavailable for a period of time within a timeout period, the COX elects to notify the terminating node of the temporary loss of communication with the mobile node, and maintains the connection to the terminating node such that the connection is not lost and is not re-originated when the mobile node becomes available within the timeout period.
