Systems, methods and interfaces are disclosed for managing communications associated with a mobile communication device. Mobile communication devices process environmental inputs and transmit mobile communication device context information to a communication management system. The context information may, for example, reflect the motion and / or geographic location of the mobile device, and may reflect the risk associated with using the device to handle a call or other communications session. The communication management system uses the context information, optionally in combination with communication device profiles, to determine how to manage incoming and / or ongoing calls or other communication sessions. Mobile device users may also be inhibited from initiating communication sessions.

A method and apparatus is configured to control a discontinuous reception (DRX) in a mobile communication system. The method includes: interrupting the DRX operation when a radio resource control (RRC) connection reestablishment procedure is initiated; transmitting an RRC connection reestablishment request message from the user equipment to an evolved node B (ENB); receiving an RRC connection reestablishment message from the ENB to the user equipment; and resuming, if the received RRC connection reestablishment message contains new DRX setting information, the interrupted DRX operation according to the new DRX setting information. The DRX operation can be interrupted or resumed at a proper time point when an RRC connection is reestablished or reconfigured or a handover is performed, thereby reducing power consumption in the user equipment.

Packet communication networks for transmission to wireless subscriber devices utilize both wireline and wireless packet routing components. The routing elements of these two different types often implement different packet scheduling algorithms, typically a form of Weighted Fair Queuing (WFQ) in the wireline portion of the network and Proportional Fairness (PF) queuing in the wireless domain. To improve resource allocation and thus end to end quality of service for time sensitive communications, such as integrated multimedia services, the present disclosure suggests adding the notion of slack time into either one or both of the packet scheduling algorithms. By modifying one or more of these algorithms, e.g. to reorder or shuffle packets based on slack times, global optimal resource allocations are possible, at least in certain cases.

A power management system is described where the handset can enter sleep or hibernation mode for a particular service, when the particular service is either not used or not available. The handset is capable of using the service, even in response to a non-user initiated incoming request for communication. The handset receives the request over the active service. The handset can then check for the availability of the inactive service, activate it, and a selection can be made between them.

Current wireless networks do not allow machine type communication (MTC) devices to have long discontinuous reception (DRX) cycles or sleep lengths. A long DRX cycle may allow MTC systems and devices to operate with much longer DRX / Sleep cycles / periods.

In some embodiments, the apparatus blanks scheduled wireless transmissions that intersect with the battery signal. In some embodiments, for a time interval subsequent to assertion of the battery signal, the apparatus operates in the peak power mode and determines energy budget for periods based on an amount of energy used for wireless transmissions in a most recent period in which transmissions were blanked in response to the battery signal. In some embodiments, in the thermal mode, the energy budget is based on thermal information for the apparatus, but may also allow carryover of unused budget from previous periods.
