Abstract: A method for reducing idle mode power consumption is disclosed. An idle mode is entered. A neighboring base station is selected. If the selected neighboring base station is assigned a high-frequency monitoring mode, a signal strength of the neighboring base station is measured. A low-frequency monitoring mode is assigned to the selected neighboring base station if the signal strength of the selected neighboring base station has been below a power threshold for longer than a time threshold. Other aspects, embodiments, and features are also claimed and described.

Abstract: To reduce the effectiveness of eavesdropping attacks, a filler such as one utilized in a data frame for link-layer LAPDm signaling may be dynamically selected to utilize a first bit pattern (first filler) generated utilizing a first algorithm when the transmissions are unencrypted, and to utilize a second bit pattern (second filler) generated utilizing a second algorithm different from the first algorithm when the transmissions are encrypted.

Abstract: Apparatus and methods are disclosed to provide for a multi-SIM wireless user equipment configured for discontinuous reception (DRX) utilizing two or more subscriptions, which may be in different radio access technologies. The user equipment is configured to originate a call using one subscription, to the same user equipment over another subscription. During the duration of a blanking window, statistics corresponding to repetitions of incoming page messages are recorded and analyzed to determine repetition behavior by the network of page messages. In this way, monitoring of the paging channel can be done during fewer than all DRX cycles, combating possible collisions between DRX cycles on different radio access technologies, and enabling reduced power consumption. Other aspects, embodiments, and features are also claimed and described.
