Problems solved by technology

[0006] Reading out the system information of neighboring cells is a time-consuming process, so that, for example, at cell area borders it may happen that for a cell where the mobile station is currently located, there is only one neighboring cell of the same operator, while there are Multiple neighboring cells of other network operators, so that the system information of bordering cells of other network operators must be read and analyzed during neighbor cell monitoring

Embodiment Construction

[0024] 1 shows two illustrative mobile radio networks of a network operator A and a network operator B separated by a national border, wherein mobile radio network A contains radio cells A0-A3, and mobile radio network B contains radio cells B0-A3 B2. Each cell is assigned a base station which is responsible for communicating with mobile stations located within the geographical range of the corresponding cell. In FIG. 1 only the corresponding base station BS is marked for the cell A0. The starting point is that the mobile station MS is currently located in the cell A0.

[0025] A different scrambling code is used by the corresponding base station in each cell, it being assumed that the two bordering network operators A and B plan to use the scrambling code jointly. In FIG. 1 , the scrambling codes used by the corresponding cells are shown in the format SC(n), where SC(n) denotes the scrambling code with ordinal number n.

[0026]Each base station of each cell, especially th...

Abstract

To accelerate the monitoring of adjacent zones in a mobile radio telephone system (A, B), signalling information is generated, in particular from the base stations (BS) that are responsible for the border zones of the mobile radio telephone system and is transmitted to the mobile station (MS). Said signalling information communicates the codes, in particular the scrambling codes, that are to be used, or not to be used for monitoring the adjacent zones, to the mobile station. After receiving the signalling information, the mobile station (MS) only monitors the transmission signals of the adjacent base stations (BS), which have been encoded using a code that corresponds with the signalling information.

Description

technical field [0001] The invention relates to a method for neighboring cell monitoring in a mobile radio system and to a correspondingly designed mobile radio system. Background technique [0002] Conventional mobile radio systems are known to be cellular, ie a corresponding mobile radio system consists of a number of radio cells, a base station being assigned to each radio cell. If a mobile station, for example a mobile telephone, is located within the geographical area of ​​a radio cell, communication with the mobile station takes place within the mobile radio system between the mobile station and the base station assigned to the temporary cell. If a mobile station moves from one cell to another, the communication connection existing between the mobile station and the base station assigned to the "obsolete" cell must be transferred to the base station assigned to the "new" cell. This process is called "handover". [0003] In order to be able to carry out such a "handov...
