Communication system that supports wireless remote programming process
First Claim
1. A method of operating a pico-cellular network to remotely program cellular radiotelephone units, said method comprising the steps of:
- identifying an electromagnetic spectrum to be used concurrently by said pico-cellular network and an independent radiotelephone network;
dedicating a first portion of said spectrum for said radiotelephone network to exclusive use in controlling and setting up calls;
dedicating a second portion of said spectrum for said radiotelephone network to exclusive use conveying voice communications for said calls; and
dedicating a third portion of said spectrum for said pico-cellular network to exclusive use in remotely programming said units so that said units may participate in calls on said pico-cellular network.

Abstract
A multiple mode, personal, wireless communications system exists within a radiotelephone network serving general customers and provides additional services to a select group of customers. The system uses handsets (32) which automatically switch between a standard cellular radiotelephone mode of operation (1901) and an enhanced cordless mode (1420) when the handsets (32) are within range of pico cells (26) that are interconnected to the public switched telephone network (20). Each pico cell is controlled via a framework of overlay cells (10b) that operates independently of the radiotelephone network and uses a unique control protocol on a small number of reserved cellular channels. Each pico cell consists of a spectrally dynamic, non-capturing, frequency agile, multi-purpose base station (26) provided at customer-selected locations to cooperate with the overlay cell framework. Each pico cell is capable of supporting multiple handsets (32) and using low power operation that achieves limited coverage. Each pico cell reduces traffic on the standard cellular radiotelephone network by independently handling registered handsets (32). An alternate line option module (22) provides wireless local interconnect capability to selectively route call traffic between land lines (24) and the standard cellular radiotelephone network. Service control units (12) and host stations (17) facilitate wireless activation and control of each pico cell and handset (32) via the overlay cell framework.

8. In a multiple mode communications system including single radio handsets capable of communicating selectively with land stations of a central radiotelephone network and local base stations supported on a local radio network, a control process for wireless activation of said local base stations and said handsets within said system comprising the steps of:
-
a) collecting at a control unit of said system, parameter information for activation of one of said local base stations and said handsets, said parameter information including a wireline telephone number for said one local base station; b) in response to wireless communications from said control unit, initializing said one local base station to receive said parameter information from said control unit; c) transmitting said wireline telephone number from said control station to said local base station using wireless remote programming communications; and d) transferring said wireline telephone number from said one local base station to one of said handsets to authorize said one handset, said step d) using wireless remote programming communications. - View Dependent Claims (9, 10, 11)

12. In a multiple mode communications system including single radio handsets capable of communicating selectively with land stations of a central radiotelephone network and local base stations supported on a local radio network, a control process for activating said local base stations and said handsets comprising the steps of:
-
a) initiating a host locate process to select a control unit to activate one of said local base stations; b) transmitting from said control unit a message addressed to a unique identity number for said one local base station using a wireless communication link; and c) upon acknowledgment of said message by said one local base station, transmitting parameter information from said control unit to said local base station using said wireless communication link. - View Dependent Claims (13, 14)
