Handoff supports for networks having different link establishment protocols

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