摘要： Techniques for enabling a user equipment (UE) to return to a wireless network after failure to obtain a particular service (e.g., voice service) are described. The UE may determine that the wireless network does not support the particular service at a first location (e.g., the current UE location). In response, the UE may disable the wireless network and may refrain from attempting to obtain the particular service (or possibly any service) from the wireless network. The UE may thereafter re-enable the wireless network based on a trigger, which may result from a timer, an event, or broadcast information from another wireless network. After re-enabling the wireless network, the UE may perform cell search and system selection and may detect and select the wireless network. The UE may determine that the wireless network supports the particular service at a second location and may obtain the particular service from the wireless network.
摘要翻译：描述了使用户设备（UE）在故障之后返回到无线网络以获得特定服务（例如语音服务）的技术。 UE可以确定无线网络不支持在第一位置（例如，当前UE位置）处的特定服务。作为响应，UE可以禁用无线网络并且可以避免尝试从无线网络获得特定服务（或可能的任何服务）。然后，UE可以基于可能由来自另一无线网络的定时器，事件或广播信息导致的触发来重新启用无线网络。在重新启用无线网络之后，UE可以执行小区搜索和系统选择，并且可以检测和选择无线网络。 UE可以确定无线网络在第二位置支持特定服务，并且可以从无线网络获得特定服务。

摘要： A method is provided for facilitating preservation of session context information during an inter-radio access technology service retry. A user equipment (UE) may initiate a data transmission for a first service over a wireless communication session with a first network. Upon ascertaining that the first service has failed over the first network, a failover procedure is initiated by sending a service request for a second service to the first network. The second service may be distinct from the first service and has the effect of suspending the wireless communication session with the first network. The UE then resends the data transmission for the first service over a second network. The UE then resumes use of the wireless communication session over the first network after resending the data transmission over the second network. This resumption is done by using context information for the wireless communication session preserved prior to the suspension.
摘要翻译：提供了一种在无线电接入技术服务重试期间便于保持会话上下文信息的方法。用户设备（UE）可以通过与第一网络的无线通信会话来发起第一服务的数据传输。在确定第一服务在第一网络上发生故障之后，通过向第一网络发送用于第二服务的服务请求来启动故障切换过程。第二服务可以不同于第一服务，并且具有暂停与第一网络的无线通信会话的效果。然后，UE通过第二网络重新发送用于第一服务的数据传输。然后，在重新发送通过第二网络的数据传输之后，UE在第一网络上恢复使用无线通信会话。该恢复通过使用在暂停之前保存的无线通信会话的上下文信息来完成。

摘要： Circuit-switched fallback (CSFB) is a technique to deliver voice-services to a mobile, when the mobile is camped in a long-term evolution (LTE) network. This may be required when the LTE network does not support voice services natively. The LTE network and a 3GPP CS network (e.g., UMTS or GSM) may be connected using a tunnel interface. The UE may register with the 3GPP CS network while on the LTE network by exchanging messages with the 3GPP CS core network over the tunnel interface. If a user receives a mobile terminating (MT) call, the UE may inform the LTE network that the UE is leaving for the call by initiating a call setup procedure. However, there may be instances where the call setup procedure may fail. For example, the UE may not be moved to the 3GPP CS network, or the UE may be moved to the 3GPP CS network but the call may fail there. Therefore, certain aspects of the present disclosure provide techniques for providing an indication of the failed call to the user.
摘要翻译：当移动台驻扎在长期演进（LTE）网络中时，电路交换回退（CSFB）是一种向移动设备提供语音服务的技术。当LTE网络本身不支持语音服务时，可能需要这样做。可以使用隧道接口来连接LTE网络和3GPP CS网络（例如，UMTS或GSM）。 UE可以在LTE网络上通过隧道接口与3GPP CS核心网交换消息来向3GPP CS网络注册。如果用户接收到移动终端（MT）呼叫，则UE可以通过发起呼叫建立过程向LTE网络通知UE正在进行呼叫。但是，可能存在呼叫建立过程可能失败的情况。例如，UE可能不会移动到3GPP CS网络，或者UE可以移动到3GPP CS网络，但是呼叫可能在那里失败。因此，本公开的某些方面提供了用于向用户提供失败呼叫的指示的技术。
