Wireless private branch exchange (wpbx) and communicating between mobile units and base stations
TLDR
In this paper, the authors proposed a protocol for seamless and reliable handoff of sessions between base stations while the mobile device is moving between picocells, by implementing a high-level of synchronization between the Base Stations and the Switch.Abstract:
Methods to create a cellular-like communication system, such as a Wireless Private Branch Exchange (WPBX) (123, 124), which includes mobile devices (121, 123) such as a standard cordless phone (handsets), particularly, mobile devices utilizing the Bluetooth short-range wireless communication protocol. The methods provide seamless and reliable handoff of sessions between Base Stations while the mobile device is moving between picocells, by implementing a high-level of synchronization between the Base Stations and the Switch (129). Base Stations of picocells having small coverage areas communicate with the handsets. The communication protocol is divided into a low-level protocol (280, 281) performed by the Base Stations and a high-level protocol (283, 284) performed by the Switch connected to all the Base Stations. The methods support mobile computing or telephony devices and communication protocols, which are not specified to handle handoffs of sessions while moving between Base Stations coverage areas in a data, voice or telephony wireless network.read more
