Method and device for establishing connection

Abstract

The invention discloses a method and a device for establishing connection, and belongs to the technical field of communication. The method comprises that: when a terminal needs to use a white spectrum to access into a current base station, the terminal inspects the locally-stored historical record information of the white spectrum; and when the terminal inspects the available white spectrum belonging to the base station in historical record information of the white spectrum, the terminal acquires a historical record of the available white spectrum, and connection of a white spectrum transmission route is established with the base station according to spectrum information in the historical record of the available white spectrum. When the white spectrum is needed to be used to access into the base station, if existence of the probably available white spectrum belonging to the current base station is confirmed, connection is established with the base station according to spectrum information in the historical record of the white spectrum so that the base station does not need to allocate spectrum resources for the terminal again. Therefore, a problem that the base station probably allocates the same white spectrum resources for the terminal repetitively is solved, and a problem of wastage of the spectrum resources is solved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and device for establishing a connection. Background technique [0002] At present, the spectrum management organization has allocated a large amount of spectrum resources to wireless applications such as TV signal propagation. However, there are some white spectrums in these allocated spectrum resources. Spectrum that has not been used for a certain period of time. If the white spectrum is applied to the existing wireless network, it can not only increase the coverage of the wireless network, reduce wireless coverage blind spots, but also reduce the transmission power to achieve the purpose of energy saving. [0003] In the prior art, in order to effectively utilize these white spectrums, on the one hand, a database is used to centrally manage white spectrum resources within an area, and the information recorded in the database includes white spectrums th...
