Abstract: Techniques are described for selecting bearers for uplink data packet transmissions. For instance, bearers may be selected using communication device-side techniques. In one example, a bearer may be selected based on a determination that other bearer(s) are not configured to support uplink data packet transmissions. In another example, a bearer may be selected irrespective of traffic flow template rules set forth by network(s) to which a communication device is connected. In yet another example, a single, default bearer that is linked to a network access point may be selected for transmission of uplink data packets that are associated with traffic flow template rules corresponding to non-default bearers. In still another example, a bearer may be selected based on its quality-of-service class identifier (QCI) value if the QCI value indicates that the bearer is configured to support uplink data packet transmissions.

Abstract: Embodiments of the disclosure generally relate to a system and method for traffic offload from a first access technology to a second access technology. For example, packets originally destined for transmission over a bearer channel associated with Long Term Evaluation (LTE) can be offloaded to a Wi-FI bearer channel in a seamless manner when available, or a non-seamless manner.

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.

Abstract: Embodiments provide an enhanced approach for Higher Priority Public Land Mobile Network (HPPLMN) search. In one embodiment, information acquired during a search (for each detected cell per frequency channel) is saved in a database and persisted in the database based on a validity time. An idle mode-to-connected mode transition by the UE, rather than aborting the search, only suspends the search for it to be resumed at a later time upon a connected mode-to-idle mode transition by the UE. Saved search data that is valid at the time of the transition is maintained and the frequency channel(s) associated with it is not re-searched in the current search. In an embodiment, the search is resumed based on weights that are associated with frequency channels, where a weight indicates a priority for visiting the frequency channel.

Abstract: Example embodiments generally relate to adapting a transmission via first wireless technology to avoid interference with a reception via a second wireless technology. For example, a user equipment (e.g. cell phone) can include radios operating according to first and second wireless radio technologies, which can include Long Term Evolution (LTE) and a technology using the industrial, scientific and medical (ISM) frequency band. When a priority request is asserted by a radio operating in the ISM frequency band, the LTE radio may abort a scheduled transmission when certain “transmission abort criteria” are satisfied.
