If the first index parameter is located in corresponding normal range (NR), illustrate that the first index parameter is normal, otherwise, illustrates the first index parameter
Abnormal, the first index parameter refers to any one index parameter at least one above-mentioned index parameter.
For example, normal minimum accesses level generally between -62~-64, and the minimum access level of pseudo-base station is usual
It is lower, such as -65.The value of normal minimum access signal quality generally near -18, -19, and pseudo-base station is usually arranged compared with
It is low, such as -25.The carrying frequency point of normal Base Station can be in presetting range, and the carrying frequency point of pseudo-base station then can be preset at this

If the first index parameter is located at corresponding normal range (NR), illustrate that the first index parameter is normal, otherwise, illustrates that the first index parameter is different
Often, the first index parameter refers to any one index parameter at least one above-mentioned index parameter.
For example, normal minimum accesses level generally between -62~-64, and the minimum access level of pseudo-base station is usual
It is lower, such as -65.The value of normal minimum access signal quality generally near -18, -19, and pseudo-base station is usually arranged compared with
It is low, such as -25.The carrying frequency point of normal Base Station can be in presetting range, and the carrying frequency point of pseudo-base station then can be preset at this
Outside range.The frequency point scanning range of normal Base Station can be bigger, and the frequency point scanning range of pseudo-base station can be smaller, so pseudo- base
Stand start scan frequency point would generally than normal Base Station start scan frequency point it is big.Normal base station can be in SIB message
GP configuring RS information, and pseudo-base station then probably will not GP configuring RS information.
