Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular to a capacity equalization analysis method and device based on an LTE network. Background technique [0002] The Long Term Evolution (LTE network, 4G network for short) is a system that integrates multi-carriers and multi-band cells for co-coverage, and has very high requirements for load balancing between carriers of different frequency bands. The network capacity balance analysis method is mainly based on the two dimensions of "RRC maximum number of connected users" and "wireless utilization rate", and analyzes the co-covered cell pairs. [0003] However, the existing methods are mainly based on "RRC maximum number of connected users" and "wireless utilization" based on equalization optimization, but this method only balances between two co-covered cells, and does not consider all co-covered LTE network frequency bands It is impossible to systematically...

Problems solved by technology

[0003] However, the existing methods are mainly based on "RRC maximum number of connected users" and "wireless utilization" based on equalization optimization, but this method only balances between two co-covered cells, and does not consider all co-covered LTE network frequency bands It is impossible to systematically balance all the co-covered cells, and the optimization method formulated lacks comprehensiveness and accuracy

Moreover, the existing method does not consider all the co-covered cells. When doing balance optimization, it is easy to push users to other co-covered cells, and solve the problem of a high-load cell, and a new high-load cell may appear in the surrounding area. The balance problem occurs repeatedly and has not been fundamentally resolved, which eventually leads to low efficiency of balance optimization
