Problems solved by technology

However, the frequency used by each carrier frequency is statically configured according to a certain frequency multiplexing method, so the frequency point allocated by the closed carrier frequency is still occupied by it during the power outage period, resulting in a waste of frequency point resources and reducing the spectrum of the system Efficiency

Embodiment Construction

[0050] The basic idea of ​​the present invention is: by setting multiple cells as a frequency sharing area, each cell in the frequency sharing area shares all the frequency resources in the dynamic frequency resource pool, and when each cell needs to load a carrier frequency due to an increase in business, it will start from the dynamic frequency resource pool. Select the unallocated frequency with the least interference or the frequency that has been allocated to other cells in the frequency sharing area from the frequency resource pool and load it. When the traffic in the cell decreases and the carrier frequency needs to be closed, the frequency corresponding to the closed carrier frequency is not used by other cells. will be marked as unallocated for loading by other cells.

[0051] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following examples are given and the accompanying drawings are given to further describe ...

Abstract

The invention discloses spectrum resource allocation method and device. A frequency sharing area is allocated in a network to set dynamic frequency resource pools in cells of the frequency sharing area. The spectrum resource allocation method includes periodically determining self-usable frequencies in the dynamic frequency resource pool by each cell of the frequency sharing area, selecting the frequency which has lowest interference and is not distributed when frequency needs to be loaded, and marking the status of the frequencies as being distributed. Frequency resource sharing among the cells in the frequency sharing area is guaranteed, a largest business bearing frequency need not be statically allocated for each cell, and frequency resources of a system are economized on the basis of guaranteeing service carrying of the cells.

Description

technical field [0001] The present invention relates to cell frequency configuration technology, in particular to a spectrum resource configuration method and device for frequency resource configuration based on a shared frequency resource pool. Background technique [0002] In the wireless network environment, due to the large-scale movement of users, the traffic will migrate from one area to another area with different time periods. For example, people in the Central Business District (CBD, Central Business District) during working hours ) Business circles gather in large numbers, and they migrate to residential areas after get off work. This is the so-called "tide traffic" phenomenon. The phenomenon of "tidal traffic" brings certain difficulties to the capacity planning in the early stage of network construction, because the traditional planning method fixedly allocates the carrier frequency and frequency points of each cell. If the network is constructed according to the ...
