Abstract
A distributed disparate wireless switching network is described herein. In one embodiment, an exemplary network architecture includes, but is not limited to, a connection origination exchange (COX), a proxy controller coupled to the COX, an access point coupled to the proxy controller, and a mobile node wirelessly coupled to the access point. The mobile node communicates with a terminating node of a network through the access point and the proxy controller using an identification maintained by the proxy controller. The COX originates a connection with the terminating node on behalf of the mobile node using the identification provided by the proxy controller. Other methods and apparatuses are also described.

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.

A method, comprising:
- a first proxy controller communicating with a connection origination exchange (COX) and one or more access points over a wired connection;
- a mobile node wirelessly communicating with at least one of the one or more access points and the mobile node communicating with a terminating node of a network through a first access point and the first proxy controller using an identification maintained by the first proxy controller;
- and
- the COX originating 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.

An apparatus, comprising:
- means for a first proxy controller communicating with a connection origination exchange (COX) and one or more access points over a wired connection;
- means for a mobile node wirelessly communicating with at least one of the one or more access points and the mobile node communicating with a terminating node of a network through a first access point and the first proxy controller using an identification maintained by the first proxy controller;
- and
- means for the COX originating 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.
