Abstract: Systems and methodologies are described herein that facilitate efficient transfer of quality of service (QoS) context during inter-radio access technology (RAT) handovers. In particular, techniques are described herein for establishing rules for whether a user equipment unit (UE) or an associated network should establish QoS for a mixed-mode application, identifying flow to bearer mappings when translating QoS across an inter-RAT handover, mapping QoS parameters of respective RATs, mitigating QoS depreciation upon multiple handovers, performing one or more actions if QoS is not acceptable in a new RAT, maintaining QoS during tunnel mode, and handling scenarios in which a UE moves between a RAT using network-initiated QoS and a RAT using UE-initiated QoS.

Abstract: A method includes receiving a data packet from a data interface and comparing an Internet Protocol (IP) address of the data interface to a destination IP address associated with the packet. Further, the method includes dropping the data packet when the IP address of the data interface does not match the destination IP address.

Abstract: Aspects disclosed in the detailed description include power saving techniques in computing devices. In particular, as data is received by a modem processor in a computing device, the data is held until the expiration of a modem timer. The data is then passed to an application processor in the computing device over a peripheral component interconnect express (PCIe) interconnectivity bus. On receipt of the data from the modem processor, the application processor sends data held by the application processor to the modem processor over the PCIe interconnectivity bus. The application processor also has an uplink timer. If no data is received from the modem processor before expiration of the uplink timer, the application processor sends any collected data to the modem processor at expiration of the uplink timer. However, if data is received from the modem processor, the uplink timer is reset.

Abstract translation: 在详细描述中公开的方面包括计算设备中的省电技术。 具体地，当数据由计算设备中的调制解调器处理器接收时，数据被保持直到调制解调器定时器期满。 然后，数据通过外围组件互连快速（PCIe）互连总线传送到计算设备中的应用处理器。 在接收到来自调制解调器处理器的数据时，应用处理器通过PCIe互连总线将由应用处理器保存的数据发送到调制解调器处理器。 应用处理器还具有上行链路定时器。 如果在上行链路定时器到期之前没有从调制解调器处理器接收到数据，则应用处理器在上行链路定时器期满时将任何收集的数据发送到调制解调器处理器。 然而，如果从调制解调器处理器接收到数据，则重置上行链路定时器。

Abstract: A method of transmitting and receiving data from a multi-homing network device to a data network is disclosed and includes defining a network policy and transmitting the network policy to a routing module. Further, the method includes receiving a route scope from the routing module. The route scope identifies a subset of data interfaces to the data network that satisfy the network policy wherein the subset of data interfaces are selected from a set of available data interfaces and wherein the subset of data interfaces includes at least one data interface.
