Abstract
A trunked communication system that supports polling requests for location information without requiring infrastructure changes. Ordinary private call talk requests are altered to include at least two inclusions of the ID code for the target communication unit. This dual representation of the ID is interpreted by the receiving unit as a poll request, to which the unit responds by providing location information on an allocated communication resource.
