Identifying an object
First Claim
1. A method of identifying an object having an identification means, comprisinggenerating and transmitting an authorization signal indicating the timeslot or timeslots allowed for the transmission of an identification request signal,receiving at a mobile station of a time division mobile communication system, in which the frequency channels used by the system are divided into timeslots, the authorization signal indicating the timeslot or timeslots allowed for transmission of the identification request signal,reading the object'"'"'s identification data from the identification means by transmitting said identification request signal by the mobile station'"'"'s radio transmitter to said identification means in the timeslot indicated by said authorization signal, and receiving an identification signal by the mobile station'"'"'s radio receiver or by the mobile station'"'"'s infrared receiver from said identification means, andidentifying said object on the basis of the identification data included in the identification signal.

Abstract
The present invention relates to a system including a mobile switching center, a base station communicating with the mobile switching center, a mobile station including a radio transmitter and a radio receiver for setting up a connection to the base station via the base station, an object including an identification mechanism, and a data processing device in which data relating to said object is maintained. For identifying the object, the mobile station reads the object'"'"'s identification data from the identification mechanism, and mechanism for transmitting the read identification data by the mobile station'"'"'s radio transmitter over the radio path via the base station further to the data processing device.
