    • A communication device establishes a connection in a congested wireless communications network environment by systematically reducing a probability of attempting to connect to a strongest, but overly-congested, cell. A transceiver of the communications device attempts at least one first Random Access Channel (RACH) procedure with a first cell that is currently designated as a serving cell. A RACH controller of the communications device detects a failure to successfully connect to the first cell via the at least one first RACH procedure, autonomously determines, based at least on a probability value, which is greater than 0% and less than 100%, whether to de-prioritize the first cell for a period of time, and, in response to determining to de-prioritize the first cell, reduces a priority value assigned at the UE to the first cell for cell selection/reselection, and assigns a selected time period during which the priority value remains reduced.
    • 通信设备通过系统地降低尝试连接到最强但过度拥挤的小区的可能性,在拥塞的无线通信网络环境中建立连接。 通信设备的收发器尝试使用当前被指定为服务小区的第一小区的至少一个第一随机接入信道(RACH)过程。 通信设备的RACH控制器检测到经由至少一个第一RACH过程成功地连接到第一小区的故障,至少基于大于0%且小于100%的概率值来自主地确定是否 为了对第一小区进行一定时间的优先级排序,并且响应于确定对第一小区进行除优先级,将在UE处分配的优先级值减小到第一小区用于小区选择/重选,并且分配所选择的时间 期间优先级值保持减少。
