摘要： A system and method for determining the mobility of a node (102) in a wireless communication network (102). The system and method determine the distance between the node (102) and at least one stationary neighboring node (102, 106, 107) at at least two or more time points, using at least two moving average filters, to arrive at two distance values. The system and method then determine the relative velocity based on the at least two distance values, and thus determine whether the node (102) is mobile.

摘要： A system and method for performing topology control in a wireless network (100). The system and method operate to enable a node (102-1) to determine the link cost of a link between itself and another node (102-2), based on the number of nodes (102, 106, 107) that would be affected by message transmission by the node (102) and the other node (102-2), and the number of nodes (102, 106, 107) that would be affected by message reception by the node (102-1) and the other node (102-2). The number of nodes (102, 106, 107) affected by the message transmission and message reception at the node (102-1) and the other node (102-2) is affected by the transmit power of the control messages sent by the node (102-1) and the other node (102-2). The node (102-1) further bases routing decisions on the calculated link costs.

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. If a user makes a mobile originating (MO) call, or 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. If the call setup procedure was either not initiated, or was initiated but failed, the UE may determine to search for a suitable CS RAT/cell on its own without instructions/commands from the network. Therefore, certain aspects of the present disclosure provide techniques for the UE to find CS services based on information collected at the UE.
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。如果用户进行移动发起（MO）呼叫或接收移动终止（MT）呼叫，则UE可以通过发起呼叫建立过程来通知LTE网络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。如果呼叫建立过程未被发起或被发起但失败，则UE可以确定自己搜索合适的CS RAT /小区而没有来自网络的指令/命令。因此，本公开的某些方面提供了用于UE基于在UE处收集的信息来找到CS服务的技术。

摘要： Certain aspects of the present disclosure propose techniques for independently signaling features supported by a user equipment (UE) in different duplexing modes. The UE may be capable of communicating in frequency division duplexing (FDD) and time division duplexing (TDD) modes. The UE may obtain a FDD-specific feature group indicators (FGIs) set and a TDD-specific FGIs set, and signal at least one of the FDD-specific FGIs set or TDD-specific FGIs set. In addition, the UE may take one or more actions to reduce the likelihood of transitioning to a mode of operation that is different from its current mode of operation.

摘要： Certain aspects of the disclosure relate generally to search of radio access technologies (RAT). For example, certain aspects of the present disclosure relate to a technique for performing higher priority radio access technology (RAT) searches in areas having a plurality of overlapping RATs, such as Global System for Mobile communications (GSM) and Long Term Evolution (LTE). According to certain aspects, a user equipment (UE) may be configured to periodically search for higher priority RATs in neighboring cells. According to certain aspects, upon finding a higher priority RAT cell, the UE may be further configured to evaluate, or “pre-evaluate”, criteria for cell reselection from found cell to the currently camped cell, while still camped on the current cell. The UE may be configured to decide whether or not to switch to the found cell based on the evaluation.

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： A CS fallback procedure handles conflict that may arise when handover operations occur during CS fallback. If CS fallback is initiated for an access terminal and handover of that access terminal is then initiated before the CS fallback completes, the target for the handover is informed of the CS fallback so that the target may perform the appropriate CS fallback operations.
摘要翻译： CS回退过程处理在CS回退期间发生切换操作时可能出现的冲突。如果为接入终端发起CS回退，然后在CS回退完成之前启动该接入终端的切换，则向CS回退通知切换目标，以便目标可以执行适当的CS回退操作。
