Abstract

The invention discloses a frequency assignment method and system. The method comprises the following steps: detecting a physical source block utilization rate of a first network in a cell; selecting physical resource blocks with matched amount from the physical resource blocks corresponding to the preset frequency range according to the physical resource block utilization rate, thereby assigning for a first network to use; and providing the residual physical resource blocks for a second network to use. According to the technical scheme disclosed by the invention, the frequency range can be flexibly assigned according to the cell PRB utilization rate, thereby guaranteeing that the first network has enough bandwidth to guarantee the quality of data business of the first network, and the residual bandwidth is used for the data business of the second network, thereby providing more high-quality service for the user.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a frequency allocation method and system. Background technique [0002] Currently, operators are carrying out LTE (Long Term Evolution, long-term evolution) services in the low frequency band of 800MHz. Operators hope to retain the original CDMA (Code Division Multiple Access, Code Division Multiple Access) voice services, that is, retain the original 2G / At the same time, 3G services can provide users with LTE data services with wider bandwidth and higher speed. [0003] Since LTE has strict restrictions and regulations on frequency bandwidth, the bandwidth of LTE mainly includes 20MHz, 15MHz, 10MHz, 5MHz, and 3MHz. Operators must simultaneously carry out CDMA services and LTE services on the 800MHz frequency band. Carrying out LTE business and CDMA business can only be allocated according to 1 LTE 5MHz and 4 CDMA frequency points (1 CDMA frequency point is 1.23M...
