METHOD FOR TERMINAL-BASED RECOGNITION OF HOME BASE STATIONS IN A CELLULAR TELEPHONE SYSTEM BY MEANS OF SUPPORT BY THE CELLULAR NETWORK
First Claim
1. A method for geographic location-finding of a cellular terminal device (101) within a cellular telephone network (110), in which each cell (102, 103, 104) of the cellular network (110) can be identified using an identifier containing a cell identification and an area identification, and whereby an identifier is emitted and whereby the cellular terminal device (101) is suited for receiving and processing these identifiers and storing one or more identifiers, a geographic location-finding of the cellular terminal device (101) within the cellular network (110) taking place by comparison of the currently received identifier to one or more stored identifiers, characterized in that when a cell identification and/or area identification of the identifier of a cell (102, 103, 104) is modified, additional information is transmitted to the cellular terminal device (101), and the new identifier is stored instead of the old identifier.

Abstract
A method for the geographical location of a mobile radio terminal within a cellular mobile radio network, in which each cell in the mobile radio network can be identified using an identifier containing a cell identification and an area identification and wherein an identifier is emitted and wherein the mobile radio terminal is suitable for receiving and processing such identifiers and for storing one or more identifiers, wherein geographical location of the mobile radio terminal within the cellular mobile radio network is effected by comparing the currently received identifier with one or more stored identifiers, with modification of the cell identification and/or of the area identification in the identifier of a cell involving transmission of a supplementary information item to the mobile radio terminal and the new identifier being stored instead of the old identifier.
