METHOD FOR THE TERMINAL-BASED RECOGNITION OF HOME BASE STATIONS IN A CELLULAR TELEPHONE SYSTEM BY MEANS OF SUPPORT BY THE CELLULAR NETWORK

摘要

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 netw ork can be identified using an identifier containing a cell identification a nd an area identification and wherein an identifier is emitted and wherein t he mobile radio terminal is suitable for receiving and processing such ident ifiers and for storing one or more identifiers, wherein geographical locatio n of the mobile radio terminal within the cellular mobile radio network is e ffected by comparing the currently received identifier with one or more stor ed identifiers, with modification of the cell identification and/or of the a rea identification in the identifier of a cell involving transmission of a s upplementary information item to the mobile radio terminal and the new ident ifier being stored instead of the old identifier.
