摘要：
The application relates to cell reselection, in particular for UTRAN and E-UTRA networks. The user terminal is configured to measure characteristics of radio channel of currently serving cell and neighbouring cells that are necessary for cell reselection. Typically such characteristics are measures relating to a signal strength and/or signal quality, such as CPICH RSCP, CPICH Ec/No in UTRAN, RSRP, and RSRQ in E-UTRA. However, utilization of either measure indicating signal strength or a measure indicating signal quality as a characteristic of a radio signal may cause serious problems, since e.g. in UTRAN the CPICH RSCP gives information on the coupling loss, but does not say anything on the interference. This problem is solved by configuring the mobile terminal to measure a value indicating signal strength and a value indicating signal quality as characteristics of a radio channel, i.e. the determination of a cell to be reselected is carried out by measuring values indicating signal strengths and values indicating signal quality.
摘要（中）：
该应用涉及小区重选，特别是用于UTRAN和E-UTRA网络。 用户终端被配置为测量小区重选所必需的当前服务小区和相邻小区的无线信道的特性。 通常，这样的特征是与信号强度和/或信号质量相关的测量，例如E-UTRA中的UTRAN，RSRP和RSRQ中的CPICH RSCP，CPICH Ec / No。 然而，使用指示信号强度的任一个度量或指示信号质量的测量作为无线电信号的特征可能引起严重的问题，因为例如 在UTRAN中，CPICH RSCP给出关于耦合损耗的信息，但是对干扰没有任何说明。 通过配置移动终端来测量指示信号强度的值和指示信号质量的值作为无线电信道的特性来解决这个问题，即通过测量指示信号强度的值和表示信号强度的值来执行要被重新选择的小区的确定 信号质量。
