Abstract: One aspect provides a modem for use at a terminal. The modem comprises a first interface, a second interface, and a processing unit. The first interface is arranged to connect to a network. The second interface is arranged to connect to a host processor on the terminal. The processing unit is arranged to perform a procedure to attempt to connect to the network via the first interface. The processing unit is also arranged to receive an indication of an operating mode that the host processor is operating in from the host processor via the second interface, where the operating mode is one of a plurality of operating modes. The processing unit is further arranged to, in the event of failure of the procedure, repeat performing the procedure at a time controlled in dependence on the received indication.

Abstract: Computer system, method and computer program product for scheduling IPC activities are disclosed. In one embodiment, the computer system includes first processor and second processors that communicate with each other via IPC activities. The second processor may operate in a first mode in which the second processor is able to process IPC activities, or a second mode in which the second processor does not process IPC activities. Processing apparatus associated with the first processor identifies which of the pending IPC activities for communicating from the first processor to the second processor are not real-time sensitive, and schedules the identified IPC activities for communicating from the first processor to the second processor by delaying some of the identified IPC activities to thereby group them together. The grouped IPC activities are scheduled for communicating to the second processor during a period in which the second processor is continuously in the first mode.

Abstract: An apparatus comprising: a first transceiver arranged to communicate over a wireless network, the first transceiver comprising a first clock; and a second transceiver arranged to communicate other than by said wireless network, the second transceiver comprising a second clock. The second sends a request signal to the first transceiver. In response, the first transceiver transitions from a first mode to a second mode and provides to the second transceiver a response signal for calibrating the second clock relative to the first clock. In the first mode the first transceiver performs zero or more calibrations of the first clock relative to the wireless network, and in the second mode the first transceiver performs at least one additional calibration of the first clock relative to the wireless network, the response signal being based on the at least one additional calibration.
