Problems solved by technology

In the existing technology, the spectrum sensing and measurement module is mainly set in the authorized base station, but in network planning, there is a certain distance between each authorized base station, and the measurement of the spectrum by the authorized base station cannot truly reflect the coverage of the authorized base station. The interference situation of the user terminal
The spectrum sensing and measurement module can also be installed in the user terminal, but due to the mobility of the user terminal, it is difficult for the LSA database to obtain the location of the user terminal in real time, which is not conducive to judging the interference situation in a specific area
In addition, in the prior art, only the measurement of the spectrum by the licensed base station is considered, and only the interference of the licensed base station by the primary user (for example, a broadcast TV network) is considered, and the interference of the primary user by the licensed base station and the relationship between each primary user are not considered. interference between

Abstract

The invention provides a detection method and device of a wired, wireless and satellite integrated network. The method comprises that position information of a set top box and a detection result, detected by the set top box, of a wireless bidirectional network are obtained; whether a broadcasting TV network to which the set top box belongs is interfered by the wireless bidirectional network is determined according to the detection result; under the condition that the broadcasting TV network to which the set top box belongs is interfered by the wireless bidirectional network, an interfering base station to which the wireless bidirectional network belongs is determined according to the position information of the set top box and the detection result; and the signal using frequency band or emission power of the wired bidirectional network of the interfering base station is adjusted to prevent the wireless bidirectional network of the interfering base station from interfering in the broadcasting TV network to which the set top box belongs. Thus, the wired bidirectional network and the broadcasting TV network can share the frequency spectrum resources in a better way.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for detecting a wired and wireless satellite fusion network. Background technique [0002] Traditional spectrum sensing and authorization systems, such as LSA (Licensed Shared Access) systems, such as figure 1 As shown, including: regulators, primary users, LSA databases, LSA controllers, and operators. Wherein, the operator includes authorized base stations. The LSA database and the spectrum sensing of the authorized base station jointly determine the spectrum resource finally used by the authorized base station. In the existing technology, the spectrum sensing and measurement module is mainly set in the authorized base station, but in network planning, there is a certain distance between each authorized base station, and the measurement of the spectrum by the authorized base station cannot truly reflect the coverage of the authorized base station. ...
