Abstract: Disclosed are methods and apparatus to prevent poor quality handoff decisions in mobile networks. The methods and apparatus effectuate a determination whether a predetermined condition concerning a cell has occurred as detected in the mobile device, such as unsuccessful handoff or a signal to noise ratio being less than a certain amount. Based on such determinations, poor quality handoff decisions can be realized by modifying or configuring the measurement report message to be sent to the serving network where the measurement report is configured to omit information concerning those cells not meeting the predetermined condition. Accordingly, these cells will not be considered in handoff decisions, thus increasing the quality of such decisions.

Abstract: In a multi-subscription wireless communication device with a shared radio frequency (RF) resource, when there is an active data communication associated with the first SIM, a tune-away may be performed to support a subscription on a second SIM. After tuning to the second network to receive data during an assigned time slot in a frame capable of carrying a common control channel the wireless communication device may determine whether a message granting or denying the requested channel access can be recovered or excluded, and skip receiving remaining frames for the message and stop tune-aways when a message granting the requested channel access can be excluded. In some embodiments determining whether the message can be excluded may include determining whether a signal-to-noise ratio for the received data burst is greater than 10 dB, and if so, determining whether the decoded data can be identified as part of a paging message.

Abstract: Real-time Short Message Service (SMS) messaging between an originating device such as a mobile device or Short Message Entity (SME) and a destination device such as a mobile device or SME. The real-time SMS messaging may be provided by initiating a call session between the originating device and the destination device, sending the SMS message within the call session, and terminating the call session prior to establishment of dedicated call traffic resources. In some embodiments, existing mobile protocol stacks may be employed by using existing voice call setup procedures to initiate the call session before sending the SMS message. In some embodiments, call session protocol stacks are extended to provide for an indication of a real-time SMS session type in the call session setup signaling. Real-time SMS messaging may be offered as a value added service, according to various embodiments. Other aspects, embodiments, and features are also claimed and described.

Abstract: Certain aspects of the present disclosure provide techniques transmitting a recommended bit rate query. A method that may be performed by a user equipment (UE) generally includes participating in a voice call with a base station using a channel and a bit rate for the voice call, measuring one or more channel quality metrics for the channel during the voice call, determining whether to transmit a query message to the base station to request a change in the bit rate based, at least in part, on the measured one or more channel quality metrics, at least one of a handover indication received from the base station or a change mode request received from the base station, and a prohibit timer, and taking one or more actions based on the determination.

Abstract: Embodiments described herein relate to extending an awake period (on duration) or an inactivity timer duration in a Connected Discontinuous Reception (CDRX) mode for a first subscription based on activities of a second subscription. A method according to some embodiments includes determining that the awake period of the CDRX cycle associated with the first subscription collides with the activities of the second subscription, and extending the awake period by an extended awake period in response to determining that the awake period collides with the activities of the second subscription. In addition, a method according to some embodiments includes determining that the inactivity timer duration collides with the activities of the second subscription, and extending the inactivity timer duration for an extended inactivity timer duration in response to determining that the inactivity timer duration collides with the activities of the second subscription.

Abstract: Various embodiments provide methods implemented by a processor executing on a mobile communication device (e.g., a multi-SIM-multi-active communication device) to opportunistically schedule a victim subscription's power monitoring activities to occur during periods in which the aggressor subscription is already scheduled not to transmit, thereby reducing the amount of time the aggressor subscription must perform Tx blanking to accommodate the victim subscription's idle-standby-mode operations. Specifically, the victim subscription's monitoring activities may be scheduled to occur while the aggressor subscription is operating in a compressed mode. As a result, the overall throughput/performance of an aggressor subscription is improved as the aggressor experiences relatively fewer blanked transmissions without affecting the victim subscription's ability to perform power-monitoring operations.
