Abstract: 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.

Abstract translation: 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。

Abstract: 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.

Abstract translation: 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。

Abstract: 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 (502). However, there may be instances where the call setup procedure may fail. For example, the UE may not be moved to the 1x network, or the UE may be moved to the 1x network but the call may fail there. If the call setup procedure was either not initiated, or was initiated but failed, the UE may determine to search (504) 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.

Abstract: Certain aspects of the present disclosure propose a method for domain selection in a multimode UE. The domain selection method may be used to select domains for short message service (SMS) and/or voice service when the UE has camped on a packet switched (PS) network such as LTE. The proposed domain selection method may take into account UE capabilities, home operator preferences, visited operator preferences, visited network capabilities, and user settings.

Abstract: Radio access interworking technologies allow a target network to notify a source network that a mobile device has moved from source network to target network, wherein mobile device does not need to perform notification to source network. Further, source network can provide a first subset of overhead information to mobile device and, after moving to target network, mobile device can receive a second subset of overhead information from target network. Further, mobile device can perform prehashing prior to moving to target network based on a channel list received from source network.

Abstract: An access terminal pre-registers with a second access network via a first access network to ensure a quick handover in the future. Frequent pre-registration attempts are avoided by implementing a hysteresis timer that restricts when a pre-registration process can be initiated. The hysteresis timer is started when pre-registration is initiated by the access terminal. No new pre-registration attempts are permitted if the hysteresis timer has not expired. An abort condition can cause the hysteresis timer to be aborted early, and a new pre-registration can be initiated. Access points in the first access network may be grouped into one or more pre-registration zones. If the access terminal moves from a first access point to a second access point, a new pre-registration is skipped if the first and second access points have the same pre-registration zone or the second access point is aware of the pre-registration zone for the first access point.

Abstract: Systems and methodologies are described that facilitate avoidance of duplicative resource allocation and/or erroneous service charges via unambiguously indicating an entity responsible for quality of service (QoS) initiation. In one example, an indication is provided to a mobile device to indicate a preference for network-initiated QoS or a preference for device -initiated QoS. QoS for a data flow can be established in accordance with the indication. For instance, the mobile device initiates QoS when the indication specifies a preference for device-initiated QoS while a network establishes QoS when the indication specifies a preference for network-initiated QoS.

Abstract: A system and method to facilitate path selection in a multihop network includes receiving by a base station a path metric associated with each of a plurality of stations neighboring to a subscriber station; comparing each of the path metrics with a current path metric; and transmitting a path selection recommendation from the base station to the subscriber station when one of the compared path metrics is better than the current path metric.

Abstract: Techniques are provided for improving broadcast efficiency in a multihop network having a base station which transmits a downlink signal, at least one relay station and at least one node associated with the relay station. The relay station relays or retransmits the downlink signal it receives from the base station to nodes associated with the relay station. The base station monitors downlink transmission metrics provided by each of the nodes associated with the relay station. Each downlink transmission metric provides a measure of the downlink signal received by a particular node from the base station. Based on the downlink transmission metrics, the base station can decide if the relay station should continue to relay or retransmit the downlink signal to the nodes associated with the relay station.
