Abstract: A method for providing indication of an SRVCC handover is disclosed. The method can include a first wireless communication device participating in a voice call with a second wireless communication device via a connection between the first wireless communication device and a first network. The method can further include the first wireless communication device determining a condition indicative of an impending SRVCC handover of the first wireless communication device from the first network to a legacy network. In response to the condition, the method can additionally include the first wireless communication device formatting a message including an indication that the first wireless communication device is going to perform the SRVCC handover and sending the message to the second wireless communication device prior to performance of the SRVCC handover.

Abstract: Throttling of transition attempts to connected mode based on user context. A wireless device may camp on a serving cell. A motion state of the wireless device may be monitored. One or more connected mode transition procedures on the serving cell may be attempted. If at least a threshold number of connected mode transition procedures fail on the serving cell while the wireless device is stationary, further connected mode transition attempts may be throttled for up to a certain amount of time. Alternatively, or in addition, the wireless device may bar itself from camping on that cell for up to a certain amount of time. Either or both of throttling connected mode transition attempts or barring cells may also be based on other aspects of user context, such as display state.

Abstract: Estimating loading and potential available throughput a serving cell of a wireless user equipment (UE) device. Physical layer metrics of a channel on which the UE communicates with the serving cell may be measured. Cell utilization of the serving cell may be calculated based at least in part on the measured physical layer metrics. A maximum available throughput of the serving cell may be calculated based on the cell utilization.

Abstract: This application discloses various techniques for call establishment using voice-over LTE (VoLTE) in networks supporting time division (TD) and frequency division duplexed (FDD) LTE communication systems. Such techniques can include systems and methods for mobile-originated calls for a UE in a TD-LTE cell, systems and methods for mobile-terminated calls for a connected UE in a TD-LTE cell and systems and methods for mobile-terminated calls for an idle UE in a TD-LTE cell. These methods and systems can leverage component carriers from a carrier aggregating capable UE to facilitate more efficient and/or effective UE call establishment.

Abstract: A method for reducing power consumption by a wireless communication device is disclosed. The method can include the wireless communication device determining that the device is experiencing an uplink power limited condition. In an instance in which the connection to the serving network was established only for a signaling purpose, the method can further include the wireless communication device sending a measurement report including an actual measured downlink signal quality value for the serving network in response to the uplink power limited condition. However, if the connection to the serving network was not established only for a signaling purpose, the method can include the wireless communication device sending a measurement report including a modified downlink signal quality value for the serving network to trigger a handover in response to the uplink power limited condition.
