Fast Handover Protocols for Wimax Networks

摘要

A method performs handover of a mobile station (MS from a current base station (BSC) connected to a target base station (BST) via a backbone in a Worldwide interoperability for Microwave Access (WiMAX) mobile communication network. The MS, before handover, transmits a Connection Identifier Request (CID-REQ) to the BST via the BSC, and receiving a Connection Identifier Response (CID-RSP) from the BST via the BSC. The MS, before handover, transmits a Subscriber Station (SS) Basic Capability Request (SBC-REQ), and receives a SS Basic Capability Response (SBC-RSP) from the BST via the BSC. Then, the MS transmits a Ranging Request (RNG-REQ) to the BST, and receives a Ranging Response (RNG-RSP) from the BST. During the handover, the MS transmits a Registration Request (REG-REQ) to the BST, and receives a Registration Response from the BST to establish the connection between the MS and the BST.
