  • Publication number: 20080046132
    Abstract: The present invention relates to preventing electronic devices (e.g., mobile terminal devices) from overheating in a communication network environment. Heat related information indicating heat generation or a simple temperature measurement at the terminal device may be sent to a network element causing the network element to adjust an inactivity period and/or a actual transmission data rate, (e.g. using a DRX/DTX parameter adjustment), so that no further rise in temperature at the terminal device occurs because of dissipation losses in the electronic components of the terminal device. Additionally, a control loop may be constituted starting at the terminal device, which detects the heat related information, provides the heat related information explicitly or implicitly to a network device, which in turn causes the network device to adjust the inactivity period and/or the transmission data rate base on the provided heat related information.

  • Publication number: 20080026698
    Abstract: A method, apparatus, software product, and network element enable a user equipment to operate in an idle mode, to sense a change in the broadcasted location area, and to then report that change to a network without requiring a dedicated connection to the network. This embodiment is achieved by sending an identifier via an uplink transport channel, and then the user equipment receives a resource allocation that is based at least partly on the identifier. The user equipment provides an uplink signal via the allocated resource, including a user equipment identity in the uplink signal. When the user equipment receives confirmation, including the user equipment identity, then the user equipment reenters the idle mode. The uplink signal provided an update as to the location area of the user equipment, although other types of signals can instead be provided this way to the network.

  • Publication number: 20070291729
    Abstract: A method, receiving device, network element, system and computer program product for controlling discontinuous reception at a receiving device of a communication network are disclosed. A regular discontinuous reception cycle of a discontinuous reception scheme is set, and this regular discontinuous reception cycle is switched to a shorter temporary discontinuous reception cycle or is switched off, in response to an event which triggers a reply of the communication network to the receiving device. Thereby, delays of network replies can be shortened or controlled in case discontinuous reception (DRX) cycles are implemented at the receiving device.

  • Publication number: 20070129017
    Abstract: A method includes determining a first time period during which evaluation should be performed of whether a received radio frequency signal meets at least one criterion, the first time period based at least partially on a second time period of discontinuous reception or transmission. The method also includes performing the evaluation of the received radio frequency signal using measurements obtained within the first time period, and determining, based on the evaluation, whether an event should be triggered. The method further includes triggering the event in response to a determination that the event should be triggered.
