Abstract:
A Radio Data Communications System (20) capable of interfacing with an existing standard communication network (10) of linked controllers (14) and fixed terminal device (16) all operating on a pre-established protocol. The Radio Data Network (20) includes a plurality of portable radio terminals (40) each of which may emulate a fixed terminal display (16) normally operating in the existing computer controlled network. There are intended to be more portable radio terminals (40) than there are LU sessions with each of such portable radio terminals (40) being associated with a particular, defined hunt group comprised of a plurality of certain of the available LU sessions and to which the portable radio terminals (40) effectively might contend for.
Abstract:
The present invention addresses the need for an apparatus and method of determining the reliability of a first signal (e.g., 116) received by a given base site (e.g., 126) without requiring the reception of additional signals (e.g., 110 and 112) by the given base site (126). The present invention provides both a method and apparatus in which another base site (e.g., 122) receives the additional signals (110 and 112) required to determine the reliability of the first signal (116). Upon determining that the first signal (116) is unreliable, the other base site (122) notifies the given base site (126) that the first signal (116) is unreliable.
