Abstract: User equipment (UE) obtains system information using a foreground or background process. The system information may include cell information that distinguishes femtocells from macrocells. Given this cell information, the UE may avoid tuning to or attempting to connect to cell types that the UE does not support. For instance, the UE may avoid connection attempts to femtocells, when the UE does not support femtocell connections.

Abstract translation: 用户设备（UE）使用前台或后台进程获取系统信息。 系统信息可以包括区分毫微微小区与宏小区的小区信息。 给定该小区信息，UE可以避免调谐到或尝试连接到UE不支持的小区类型。 例如，当UE不支持毫微微小区连接时，UE可以避免对毫微微小区的连接尝试。

Abstract: Systems and methods for providing dynamic substream definition and handover are provided. In embodiments, a user device includes a multiple radio access technology (RAT) communications modules and a communication controller. Each RAT communication module is further configured to communicate using a different RAT. The user device identifies available networks for communication. Then, the controller determines whether a need to split a communications stream exists (e.g., the user device is engaged in a bandwidth intensive application). If the communications stream is to be split, the controller defines the substreams (either equally or unequally) and assigns a first substream to a communication pathway in a first available network and assigns a second substream to a communication pathway in a second available network. The destination then recombines the substreams. In embodiments, the controller inserts synchronization in the substreams.

Abstract: Techniques are described herein for prioritizing higher priority data packets by reserving sequence numbers for assignment to higher priority data packets received after lower priority data packets are assigned sequence numbers. Higher priority data packets may also be prioritized by estimating an amount of data that can be sent in a single uplink allocation, limiting the amount of data packet data sent during a designated uplink allocation to the estimated amount of data, and encrypting high priority data packet(s) received previous to the designated uplink allocation. Higher priority data packets may also be prioritized by encrypting and placing high priority data packet(s) received in a queue, and subsequently re-encrypting any unsent lower priority data packets that were encrypted in the queue before the high priority data packet(s) were received.
