Problems solved by technology

[0015] In the "cell fingerprint" approach, it can be seen that the main disadvantage is that the updating of the "cell fingerprint" has to happen by the network operator changing the cell Informing cellular operators of network reconfiguration

Embodiment Construction

[0052] exist figure 1 In the situation shown, a cellular terminal 101 arrives at the geographic location of its own base station, i.e. a home BS 100, and at this local location in a cellular land mobile network 101 from several cells 102, 103 of a macrocell network, i.e. a cellular land mobile network 110 . 104 Receive information as a "cell fingerprint" with a cell identity (CI) and a tracking area identity (TAI) in the E-UTRAN case, and in other cases a local area for UMTS or GSM ( LA) corresponding tracking area information.

[0053] A configuration 130 of the local geographic position can be determined, stored in the cellular terminal, originating from the cell identifiers of the cells 102,103,104. The configuration 130 identifies the corresponding geographic location in the land mobile network 110 . When the stored configuration is consistent with the current cell constellation configuration 130, the search for its own base station 100 is triggered, ie, this is the trig...

Abstract

Process for geographical location of a cellular terminal (101) within a cellular land mobile network (110) for finding a certain base station (100), each cell (102, 103, 104) of the land mobile network (110) an identifier sent [sic], the combination of the identifiers of the identifiers which have been received at a certain geographical position delivering a unique configuration (130, 140), the cellular terminal (101) being suited to storing these configurations (130, 140), when agreement of the current configuration (130, 140) with the configuration (130, 140) stored in the cellular terminal (101) is established a search of the cellular terminal (101) for the base station (100) being triggered, by means of the base station (100) the configuration (130, 140) being checked at the geographical position of the base station (100) and when the identifier of the cell (102, 103, 104); is modified, a new identifier and / or the new configuration (140) for transmission to the cellular terminal (101) being made available, and the new identifiers and / or the new configuration (140) being stored in the cellular terminal (101).

Description

technical field [0001] The invention relates to a process for discovering the geographic location of a cellular terminal within a cellular land mobile network of a base station, each cell in the land mobile network transmits an identifier and can be based on this identifier and the location received at a geographic location Combinations of cell identifiers in the neighborhood are identified, convey a unique configuration, the geographic location of the base station has such a unique configuration, the cellular terminal is adapted to receive and process these identifiers and store one or more identifiers and / or configurations, when established The search of the cellular terminal for the base station is triggered upon the coincidence of the current configuration with the configuration stored in the cellular terminal. [0002] In particular, the invention relates to a process for updating additional information stored in a terminal for supporting terminal-based search functions o...
