AR9216: CELL_RADIO_PDTCH_AVG_QUEUE_LEN
This measurement provides the average length of the PDTCH queues in the BSC in a granularity period. If the measurement value is always high, you can infer that the PS services are busy. In this case, you are advised to configure more static PDCHs, or increase the value of Maximum Ratio of Threshold of PDCHs to trigger more TCHFs to be converted into PDCHs.
byte.
In a granularity period, Average PDTCH Queue Length is calculated on the basis of Total Sampled PDTCH Queue Lengths and Sampling Times of PDCH Queue Length. The Sampling Times of PDTCH Queue Length and Sampling Times of PDCH Queue Length have the same value. In the formula, Sampling Times of PDCH Queue Length is used.
Average PDTCH queue length = Total Sampled PDTCH Queue Lengths/Sampling Times of PDCH Queue Length
