Method and arrangement for detecting a radio coverage
View Patent ↗A method and arrangement for detecting a radio coverage in a synchronous multicellular mobile radio system having a multitude of synchronous base stations that are connected to an evaluating unit are provided. All base stations are operated in succession in a measuring operating mod. A respective field intensity of base stations that are locally adjacent and in a normal operating mode is measured, and the respectively measured field intensity data are evaluated by the evaluating unit. This enables a sufficient radio coverage to be determined in a highly cost-effective manner and, optionally, to be corrected.
1. An arrangement for detecting a radio coverage in a multicellular mobile radio system, comprising:
an evaluation unit; and
a plurality of base stations communicatively connected to the evaluation unit, the plurality of base stations operating in a normal operating mode,
wherein the plurality of base stations are consecutively switched, one at a time, from the normal operating mode to a measuring operating mode,
wherein the one switched base station in the measuring operating mode receives signals from each of the base stations locally adjacent to it and measures (a) a field strength of each of the base stations locally adjacent to it, with the locally adjacent base stations in the normal operating mode, and (b) a quality of synchronicity between the one switched base station and each of the locally adjacent base stations, with the locally adjacent base stations in the normal operating mode, and
wherein the evaluation unit receives the measured field strength and measure of synchronicity quality for evaluation.
2. The arrangement as claimed in claim 1 , wherein each measured field strength is provided to the evaluation unit with an identification of the measured base station.
3. The arrangement as claimed in claim 1 , wherein the evaluation unit modifies the mobile radio system based on a result of the evaluation.
4. The arrangement as claimed in claim 1 , wherein the evaluation unit creates a field strength map for determining the position of a mobile unit.
5. The arrangement as claimed in claim 1 , wherein the mobile radio system is designed in accordance with a Digital Enhanced Cordless Telecommunications standard.
6. The arrangement as claimed in claim 1 , wherein the radio coverage is detected in cycles, and wherein a result of the current evaluation is compared with a result of a previous evaluation of measured field strength.
7. The arrangement as claimed in claim 6 , wherein the measured field strength is provided to the evaluation unit with an identification of the measured base station.
8. The arrangement as claimed in claim 7 , wherein the evaluation unit modifies the mobile radio system based on a result of the evaluation.
9. The arrangement as claimed in claim 8 , wherein the evaluation unit creates a field strength map for determining the position of a mobile unit.
10. The arrangement as claimed in claim 9 , wherein the mobile radio system is designed in accordance with a Digital Enhanced Cordless Telecommunications standard.
