Signaling and control architecture for an ad-hoc ATM LAN
First Claim
1. A method of tracking and locating mobile users in an ATM network, wherein said network includes a plurality of portable base station (PBS) switching nodes coupled together to form said ATM network to enable communication between said nodes, said method comprising the steps of:
- at a local PBS, responsive to receiving a registration message from of a mobile user, recording said registration at said local PBS to establish an association with the mobile user;
generating a broadcast page from a local PBS associated with a calling mobile user to find a local PBS associated with a called mobile user identified in a call request received from the calling mobile user;
responding to said broadcast page from another local PBS associated with said called mobile user as a result of said called mobile user having registered with the other local PBS.

Abstract
The present invention is a signaling and control architecture for establishing a connection between mobile users in a wireless ATM LAN. The ATM LAN includes a plurality of portable base station (PBS) switching nodes coupled together to enable communication between said nodes, wherein the nodes are configurable in an arbitrary topology to form an ad-hoc network. The present invention includes network management techniques for configuration of data tables used for connection control. Mobility management techniques are disclosed to handle mobile sign-ons and idle handoffs, locate mobile users during connection and setup and perform handoffs when a mobile is actively involved in a connection. Connection control procedures are also included for setting up and releasing connections on demand.

20. An architecture for tracking and locating mobile users in an ATM network, wherein said network includes a plurality of portable base station (PBS) switching nodes coupled together to enable wireless communication between said nodes, said architecture comprising:
-
means for generating a registration message to a local PBS upon power-up of a mobile user associated with said local PBS, means for recording said registration message at said local PBS; means for generating a broadcast page from a local PBS associated with a calling mobile user to find a local PBS associated with a called mobile user; means for responding to said broadcast page from said local PBS associated with said called mobile user if said called mobile user is registered with a PBS within said network. - View Dependent Claims (21, 22, 23)
