Problems solved by technology

[0003] Here, the selection of available channel spectrum resources by SAS has caused certain limitations. Operators cannot actively select the desired channel spectrum resources according to their own needs, and can only use channel spectrum resources that have been allocated by SAS.

Embodiment Construction

[0063] An embodiment of the present invention provides a channel spectrum resource selection method, a first device, and a second device, which are used to select target channel information from currently available channel information according to channel requirements, Meet the needs of operators.

[0064] The Spectrum Access System (SAS) serves as a centralized management center for the use of the 3.5GHz spectrum, and the SAS directly or indirectly controls the CitizensBroadband radio Service Device (CBSD) that uses the 3.5GHz spectrum. Such as figure 1 As shown, it is a schematic diagram of the application scenario of the spectrum access system, which may include SAS, CBSD, database, primary user, environment sensing capability (Environment Sensing Capability, ESC), domain proxy (Domain Proxy) and unit management system (Element Management System) , EMS) and other equipment. It should be noted that the number of CBSDs is not limited. The following is a brief description o...

Abstract

The embodiment of the invention discloses a method for selecting channel spectrum resources, which is used to select a target channel according to channel requirements and meet the requirements of operators. The method in this embodiment of the present invention includes: the first device sends a spectrum query request to the second device, the spectrum query request includes channel feedback information, and the channel feedback information is used to instruct the second device to feed back the current Information about available channels; the first device receives a spectrum query response sent by the second device, and the spectrum query response includes information about the currently available channels; the first device obtains the information from the information about the currently available channels Selecting a target channel, where the target channel corresponds to the channel requirement of the first device.

Description

technical field [0001] The present invention relates to the communication field, and in particular to a channel spectrum resource selection method, a first device, a second device and a channel spectrum resource selection system. Background technique [0002] With the widespread popularization of smart terminals and the continuous growth of mobile data services, mobile operators' networks are under enormous pressure. By deploying small cells (Small Cell) and adding new frequency points are means to increase the data traffic of wireless network. With abundant bandwidth resources (3400-3600MHz, LTE Band42 / 43), the 3.5GHz frequency band has become a global hotspot frequency. In the United States, since it is difficult to clean up the main users on the 3.5GHz frequency band, the Federal Communications Commission (FCC) of the United States began to study the use of 3550 in the form of Spectrum Access System (SAS) spectrum sharing in 2014. - 3700MHz and a total of 150MHz of spec...
