METHOD AND APPARATUS FOR DETECTING CELL OUTAGE AND CONTROLLING TRANSMISSION POWER |
摘要 |
Disclosed are a method and an apparatus for detecting a cell outage and controlling transmission power. The method of detecting the cell outage includes: receiving a Radio Link Failure (RLF) message from a User Equipment (UE) or an adjacent BS; acquiring Reference Signal Received Power (RSRP) and Reference Signal Received Quality (RSRQ) of the UE with respect to a serving cell and adjacent cells before RLF generation, which are included in the RLF message; calculating a Signal to Interference plus Noise Ratio (SINR) of the serving cell by using the acquired RSRP and RSRQ; calculating an SINR of a best adjacent cell having a largest RSRP among the adjacent cells of the UE by using the acquired RSRP and RSRQ; and comparing an SINR of a best cell having a largest SINR between the serving cell and the best adjacent cell with a preset reference value and determining whether the cell outage has been generated. |
