Network architecture and signaling for wireless personal communications
TLDR
A distributed microcellular architecture based on the IEEE 802.6 Metropolitan Area Network is proposed, and is shown to meet anticipated personal communications service (PCS) needs, and a distributed subscriber database architecture is proposed to facilitate call setup, tracking of roamers and handoffs.Abstract:
A distributed microcellular architecture based on the IEEE 802.6 Metropolitan Area Network (MAN) is proposed, and is shown to meet anticipated personal communications service (PCS) needs. A method is presented to calculate MAN coverage in urban areas, and is used to demonstrate coverage of approximately 50 city blocks per MAN. A distributed subscriber database architecture is proposed to facilitate call setup, tracking of roamers and handoffs. To fully utilize MAN bandwidth, a quick method for the heat stations to switch on/off isochronous slots is proposed to facilitate adaptation to PCS traffic level variations. Call setup and handoff procedures are detailed. The PCS signaling overhead is calculated to be 15% of the capacity required to carry voice traffic. >read more

TL;DR: A novel dynamic guard channel scheme is proposed which adapts the number of guard channels in each cell according to the current estimate of the handoff call arrival rate derived from the current number of ongoing calls in neighboring cells and the mobility pattern, so as to keep the handoffs call blocking probability close to the targeted objective.

TL;DR: In this paper, an interface server accesses a routing and administration database to determine a destination address of a destination interface server based on the area code of the called number, and the telephony server inserts the destination address to the data packets for a destination server for a second communications system.
