Network frequency collaboration method and device based on macro-micro sector service absorption

Abstract

The invention discloses a network frequency collaboration method and device based on macro-micro sector service absorption, and the method comprises the steps: determining the macro-micro type of a station; calculating a first inflection point value of the business volume bearing capacity of each frequency band, and further calculating the business volume bearing capacity of the whole sector after frequency coordination; judging whether the service volume bearing capacity of the whole sector is greater than or equal to the current service volume of the station sector after frequency coordination; if yes, carrying out the frequency dechirping processing; if not, according to the macro-micro type of the station, calculating the total value of the absorption service volume of the peripheral sectors by adopting a peripheral opposite sector absorption mode or a peripheral sampling point proportion pre-estimation absorption capability mode; and determining a frequency coordination scheme according to the business volume bearing capability of the whole sector after frequency coordination, the current business volume of the station sector and the total value of the business volume absorbed by the peripheral sectors. According to the scheme, different absorption modes are formulated according to absorption characteristics of macro and micro sectors, and scientific frequency collaboration is realized.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a network frequency coordination method and device based on macro and micro sector service absorption. Background technique [0002] With the rapid development of mobile network technology, people's demand for mobile communication services, especially the demand for data services has increased sharply, which brings challenges to the existing communication systems. In order to meet the needs of users for higher communication rates, shorter communication delays, and more communication connections, 5G technology has emerged as the times require. Based on the frequency band configuration of the current mobile 4G network deployment, there is interference between the 4G frequency band and the 5G frequency band. How to do a good job of 4G / 5G frequency coordination while ensuring the quality of the 4G network is an urgent problem to be solved. . [0003] There are mainly...

Problems solved by technology

However, adopting the first solution will have a great impact on the quality of the 4G network under high load. When the capacity is not fully replenished, the frequency will be cut directly, and the user page rate will drop by 44%, and the high-load cell will increase by 60%.

However, the second solution does not comprehensively consider the capacity redundancy of some 4G sites on the current network and the impact of 5G rollback on 4G capacity, which will result in waste of investment. At the same time, it will take a long period of time to purchase and approve a large number of capacity replacement equipment. Affect the progress of 4G / 5G frequency coordination
