Abstract

In a communication system in which a roaming node seeking network access among different networks which are implemented with different network interface layer protocols, handoff schemes are instituted whereby the node may freely move from one network to another with reduced levels of interruptions with respect to the network access. Prior to and at The onset of a handoff, the node receives an indication for the handoff. The indication may he embodied in various forms such as a signal message indicating a change of the SID (System Identification), NID (Network Identification), or PZID (Packet Zone Identification). Alternatively, the indication can he in the form of information straightforwardly included in a data packet sent to the roaming node prior to the handoff. As another alternative, the indication can be implemented as distinguishable message patterns sent to the node in which different message patterns can be sent by different networks supporting different network interface layer protocols.
