摘要： An MME keeps track of network tracking mobility characteristics by periodically updating a TA transition probability matrix derived from a global table that maintains UE movement data in the network by noting current TA and most recently known previous TA of each EU for every TAU event and paging event. The MME also maintains data of the number of paging events and TAUs performed by each UE and stores a paging ratio versus TAU for each UE. The UE characteristics, UE paging ratio, and network mobility characteristic are utilized in an algorithm that constructs a TA list for each UE designed to minimize the overall traffic cost function for paging events and TAU events for that UE and the overall network. Optionally, the TA list for each EU is constrained to meet certain minimum performance characteristics such as a predetermined paging success rate target and/or a predetermined delay bound target.

摘要： In order to provide an early and more accurate determination of network problems, current NPI OMs are compared with samples of recent historical NPI OMs so that changes in the NPI OM are detected based on current overall network conditions rather than on conditions that may have existed at statistically insignificant earlier operational periods. By constantly adjusting a performance threshold, against which the current NPI OM is compared, by using a smaller and very recent sampling of NPIs (in the case of sudden and abrupt performance-NPI degradation detection) or a larger and greater number of NPIs over a wider time period (in the case of slow and persistent NPI degradation detection) to establish the threshold, detection results are more accurate and meaningful.
摘要翻译：为了提供早期和更准确的网络问题的确定，将当前的NPI OM与最近的历史NPI OM的样本进行比较，以便根据当前的整体网络条件而不是基于现有的条件，检测NPI OM的变化在较早的运营期间统计学上无关紧要。通过不断调整当前NPI OM比较的性能阈值，通过使用较小且最近的NPI采样（在突发和突发性能 - NPI劣化检测的情况下）或更大和更多数量的NPI超过更宽的时间段（在持续不断的NPI退化检测的情况下）建立阈值，检测结果更准确有意义。
