摘要： At least one portable RF communications device in conjunction with at least two fixed- location service-area antenna stations respectively capable of RF communication with the at least one device performs the steps of: (I) using a portable device at a selected location to measure RF communications signals from the plurality of local fixed-location service-area antenna stations and electronically storing at least two of the respective reception signal strength measurements; and (II) monitoring a portable device location by causing the device to measure reception signal strength associated with local fixed-location service-area antenna stations signals, and to electronically compare these measurements with the stored at least two measurements.

摘要： A protocol for location-based telecommunications redundancy, operable at a data-communications topology juncture having at least two telecommunications media thereat, and the protocol includes the steps of: (1) On the occurrence of a call-processing request from a caller to a recipient-e.g. using a last known present location of the recipient's mobile phone; and (2) Using the current location, second software at-the-juncture propagating the request to "ring" at two call-receiving devices closest to the current location-wherein one of the devices is a mobile telecommunications device of the recipient and the other of the devices is a terrestrial device of the recipient that is closest to the current location of the recipient.
