Problems solved by technology

[0003] For the cellular mobile communication system, on the one hand, the frequency reuse of the main common control channel and the traffic channel is inconsistent, so the main common control channel C / I cannot truly reflect the status of the traffic channel C / I
On the other hand, in the network engineering construction stage, the number of users is small and the network is in a light load state. The service channel C / I measured by the drive test terminal can only reflect the service channel quality under the condition of low network load, but cannot effectively reflect the current Traffic channel interference situation under high network load
[0004] In summary, related technologies cannot accurately determine the service channel quality under high network load conditions, so that network coverage optimization and frequency optimization cannot be effectively performed to adapt to high-load cellular mobile communication systems

Background technique [0002] In the cellular mobile communication system, the carrier-to-interference ratio C / I of the main common control channel measured by the road or the carrier-to-interference ratio C / I of the traffic channel measured by the road is usually directly used as the quality of the traffic channel. In network optimization, the C / I of the main common control channel is also used as the main basis for coverage optimization. [0003] For the cellular mobile communication system, on the one hand, the frequency reuse of the main common control channel and the traffic channel is inconsistent, so the main common control channel C / I cannot truly reflect the status of the traffic channel C / I. On the other hand, in the network engineering construction stage, the nu...
