ioi,tch空闲状态下的干扰强度（IOI, TCH interference intensity in idle state）

ioi,tch空闲状态下的干扰强度（IOI, TCH interference intensity in idle state） INTERF_ON_IDLE (TCH strength in the idle state) Interfere_on_idlesse Interference in idle mode, the normal range is less than or equal to 80 (that is, each time slot is less than 10) A repeater uplink interference problem caused by the existing problem of uplink interference is the most common cause of repeater uplink interference, especially some illegal users to install the repeater, because the price is low, the performance of various devices is not good, strong problem caused by uplink interference. The reason of repeater interference is the white noise space and the repeater itself is amplified by the uplink noise together with the mobile phone signal together to arrive at the base station receiver caused by uplink interference of base station. The normal repeater manufacturers in the installation of repeater when considering this problem, the repeater uplink noise level (uplink noise floor) is adjusted, and the appropriate selection of donor cell, in order to reduce the uplink interference base station system. But some users to install the repeater does not consider the problem, it will cause a strong uplink interference to surrounding base stations. The statistics of repeater uplink interference caused by the law: nothing to do with the traffic, as long as the repeater station, IOI statistics 24 hours off the repeater, the spectrum returned to normal. For the illegal repeater, a practical solution is to help users solve the problem of signal coverage, and remove the repeater interference. Operators to solve the installation of repeater signal blind area, should give full consideration to the uplink noise level at the bottom, avoid when solving signal coverage, will introduce interference within the network, the network quality deterioration Two, Jammer (mobile signal blocker) interference Jammer is for special purpose, an interference method taken to block the mobile communication signal, mainly
