Abstract: A user equipment (UE) collects system information blocks (SIBs) in two phases so the UE can select a target cell to fall back on for a circuit switched fall back (CSFB) call. During the first phase, the UE collects short-period SIBs indicating location IDs for the top N cells corresponding to N strongest frequencies from a frequency list in a redirection command. If the UE finds a cell with a location ID matching the location ID in a previous combined registration, and the synchronization channel quality of the cell exceeds a threshold, the UE selects the cell as the target cell. The UE stops collecting short-period SIBs for other cells. During the second phase, the UE collects mandatory long-period SIBs for the selected target cell only. This reduces potential CSFB call setup latency by avoiding a location area update procedure before circuit switched voice call establishment in a 2G/3G network.
Abstract translation: 用户设备（UE）分两个阶段收集系统信息块（SIB），以便UE可以选择一个目标小区回退以进行电路交换回退（CSFB）呼叫。 在第一阶段期间，UE在重定向命令中从频率列表收集指示对应于N个最强频率的前N个小区的位置ID的短周期SIB。 如果UE在先前的组合注册中找到具有与位置ID匹配的位置ID的小区，并且小区的同步信道质量超过阈值，则UE选择该小区作为目标小区。 UE停止收集其他小区的短期SIB。 在第二阶段期间，UE仅为所选择的目标小区收集强制性的长周期SIB。 这通过在2G / 3G网络中的电路交换语音呼叫建立之前避免位置区域更新过程来减少潜在的CSFB呼叫建立延迟。

Abstract: A user equipment (UE) in a high speed state returns back to a frequency on a dedicated network (e.g., LTE) or a different frequency after a circuit switched fallback call is released from another network based on a signal quality of the frequency on the dedicated network. In one instance, it is determined whether the UE is in a high speed state. Based on the determination, the UE searches a selected frequency and/or inter-frequency neighbors, when attempting to return to the dedicated network from a second RAT after a circuit switched fallback (CSFB) call is released from the second RAT.
Abstract translation: 基于频率的信号质量，在高速状态的用户设备（UE）在从另一网络释放电路交换回退呼叫之后返回到专用网络（例如，LTE）或不同频率上的频率 专用网络 在一种情况下，确定UE是否处于高速状态。 基于该确定，当在从第二RAT释放电路交换回退（CSFB）呼叫之后尝试从第二RAT返回到专用网络时，UE搜索所选频率和/或频间邻居。

Abstract: A user equipment (UE) measures a signal quality of a serving cell and/or a signal quality of one or more cell reselection target cells. The UE reduces latency of circuit switched fallback (CSFB) procedure when a cell reselection from a first RAT to a second RAT is concurrently triggered. In one instance, the UE reduces latency by determining whether to abort a cell reselection procedure based on a signal quality of a serving cell and/or a signal quality of at least one cell reselection target cell, when a circuit switched fall back call has been triggered.
Abstract translation: 用户设备（UE）测量服务小区的信号质量和/或一个或多个小区重选目标小区的信号质量。 当从第一RAT到第二RAT的小区重选被同时触发时，UE减少电路交换回退（CSFB）过程的等待时间。 在一种情况下，当电路交换回退呼叫已经被执行时，UE通过基于服务小区的信号质量和/或至少一个小区重选目标小区的信号质量来确定是否中止小区重选过程来减少等待时间 触发。

Abstract: A method and apparatus for wireless communication facilitates fast return to a LTE network after circuit-switched fallback occurs. A redirection command is received from a first RAT falling back to a second RAT. The redirection command includes idle mode mobility information and includes a priority level for a list of frequencies associated with the first RAT. Frequencies of the first RAT are searched based on priority levels in the idle mode mobility information of the redirection command. The UE returns to a cell detected in a frequency of the first RAT when a signal strength of the cell is above a threshold value.

Abstract: A user equipment (UE) reduces delays associated with returning to a first radio access technology (RAT) after redirection to a second RAT. The UE moves from a first radio access technology (RAT) to a second RAT to permit a circuit switched (CS) call. When the UE fails to return to the first RAT after releasing the circuit switched call on the second RAT, the UE establishes a first packet switched (PS) call on the second RAT. The first packet switched call may be triggered by a background application. The UE periodically suspends communications during the first packet switched call on the second RAT. The UE creates a forced measurement gap during suspension of the first packet switched call in the second RAT to monitor the first RAT and returns to the first RAT to resume the first packet switched call when the monitoring detects a cell in the first RAT.
Abstract translation: 用户设备（UE）在重定向到第二RAT之后减少与返回到第一无线电接入技术（RAT）相关联的延迟。 UE从第一无线电接入技术（RAT）移动到第二RAT，以允许电路交换（CS）呼叫。 当UE在第二RAT上释放电路交换呼叫之后UE不能返回到第一RAT时，UE在第二RAT上建立第一分组交换（PS）呼叫。 第一个分组交换呼叫可以由后台应用触发。 UE在第二RAT上的第一分组交换呼叫期间周期性地暂停通信。 UE在第二RAT中的第一分组交换呼叫暂停期间创建强制测量间隙以监视第一RAT，并且当监视检测到第一RAT中的小区时返回到第一RAT以恢复第一分组交换呼叫。

Abstract: A user equipment (UE) reduces random access procedure delays when reselecting or redirecting from a cell of a first radio access technology (RAT) by preventing a persistence check before initiating the random access procedure. In one instance, the UE prevents the persistence check by preventing collection of system information including a scaling factor used for the persistence check before initiating the random access procedure.
