论文摘要
在蜂窝网络中，需要跟踪用户设备（UE），以便可以通过输入数据并保留上下文信息（例如可用于UE OET OINCORTENT TRANSLAST的加密键）来达到它们。通常，UES测量由网络广播的参考信号传输，并根据某些标准向网络报告，该标准允许网络以足够的准确性了解UE位置。另一种方法是让UES发送网络可以检测到以跟踪UE位置的参考信号。这减少了UES测量和报告的需求，而它需要一些资源来进行上行链路传输。在本文中，我们提出并评估了一个共同跟踪正在移动的UE组的解决方案。结果表明，可以通过低资源消耗来有效地跟踪UES。
In cellular networks user equipment (UE) need to be tracked so that they can be reached by incoming data and to keep context information such as encryption keys available for UE originated transmission. Typically UEs measure reference signal transmissions that are broadcasted by the network, and report to the network based on some criterion that allows the network to know the UE location with sufficient accuracy. An alternative approach is to let the UEs send out reference signals that the network can detect to track the UE location. This reduces the need for the UEs to measure and report, while it requires some resources for uplink transmission. In this paper we propose and evaluate a solution for jointly tracking groups of UEs that are moving together. The results show that UEs can be tracked efficiently with low resource consumption.
