The present invention provides a frequency band resource sharing method, device, electronic equipment, and storage medium. The method includes: obtaining the state of the first sub-frequency band, wherein the state of the first sub-frequency band includes: a busy state and an idle state, and a police number The initial allocation frequency band of the trunking PDT system is divided into the first sub-band and the second sub-band, the first sub-band is allocated to the police digital trunking PDT system, and the second sub-band is allocated to the long-term evolution LTE system; judge the first sub-band Whether the state of the state is idle; if the judgment result is yes, the first sub-frequency band is allocated to the LTE system for use. By monitoring the state of the first sub-frequency band, when the first sub-frequency band is in an idle state, the first sub-frequency band is allocated to the LTE system for use, thereby improving the utilization rate of the first sub-frequency band, and realizing dynamic sharing of frequency band resources between the LTE system and the PDT system.
Description
technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a frequency band resource sharing method, apparatus, electronic device and storage medium. Background technique [0002] In the wireless communication technology, the most important and the most basic is the wireless frequency band resource. However, at present, most of the frequency band resources below 1 GHz have been allocated to narrowband systems, and it is difficult to allocate a relatively suitable wider segment of frequency band resources suitable for exclusive use by the Long Term Evolution (Long Term Evolution, LTE) system. [0003] In order to solve the above problems, some frequency bands of the bandwidth resources used by the existing Police Digital Trunking (PDT) system are allocated to the LTE system, and the remaining bandwidth resources are allocated for use by the PDT system itself. LTE shares the broadband resources of the PDT system. ...
