  • Patent number: 8818321
    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.

  • Patent number: 8797931
    Abstract: A method and system for establishing a wireless connection between a portable computer system and a wireless network, particularly when the portable computer system goes out of coverage and a wireless connection needs to be re-established. The portable computer system has a main processor and a digital signal processor (DSP). The main processor is placed in a low power mode, conserving battery power. When the portable computer system goes out of coverage, broadcast channels used by the wireless network are scanned by the DSP instead of the main processor to identify channels that have sufficient signal strength for the wireless connection. Thus, the main processor remains in the low power mode. When the DSP identifies acceptable channels, it wakes up the main processor and identifies the channels having sufficient signal strength. The main processor then establishes a wireless connection using one of the channels identified by the DSP.

    Abstract: There are disclosed a random access method for establishing an individual channel between a radio communication terminal device and a base station device in a short time and a radio communication terminal device executing the random access method. In this device, in step ST320, a RACH sub-channel allocation unit (211) allocates a transmission packet inputted from a replication unit (202) to an arbitrary sub-carrier at the RACH arbitrary time slot at random. In step ST330, an allocation unit (210) judges whether an overlap is generated in the allocation result obtained by the RACH sub-channel allocation unit (211). When the allocation unit (210) judges that an overlap is generated in the allocation result, the allocation unit (210) causes one of the RACH sub-channel allocation units (211) which has caused the overlap to again perform allocation of step ST320. On the other hand, when judgment is made that no overlap is generated in the allocation result, step ST340 is executed.

One way of doing this with cellular telephones that are in the idle state is to use a baiting beacon to bait and automatically call all the cellular telephones in an area that are in the idle state. If the call to a given cellular telephone is not answered by a human voice, the cellular telephone is suspect. Another way of doing this with cellular telephones that are in the traffic state is to use surgical analysis to examine the DTX pattern for the telephone. If it indicates persistent silence, the cellular telephone is suspect. The surgical analysis may also be used to trace the DTX pattern back to another telephone that is controlling the suspect cellular device.

  • Patent number: 8724536
    Abstract: Embodiments provide power-efficient mechanisms for communicating small amounts of information to receiver devices within a mobile broadcast system. A generic transport mechanism enables transmitting data relevant to upper layer protocols in a lower layer sub-channel so multiple information summary flows can share the same physical layer sub-channel. Data fields are added to the Overhead Information Service (OIS) channel to provide power-efficient logical channels for carrying the summary information. Data from the power-efficient logical channels are provided to an upper protocol layer that receives the information summary flows. Information summary flow may carry a version number of an information flow in the broadcast signal, codes or other information. Receiver devices periodically monitoring the OIS receive the information summary flows.

  • Patent number: 8725179
    Abstract: A system and method for detecting spectrum holes in a region is disclosed. The system comprises a requesting module, a detecting module and an aggregation module. The requesting module retrieves channel availability data for a region. The channel availability data describes potential availability of a channel. The detecting module obtains a set of values for the channel by spectrum sensing at a set of locations in the region based at least in part on the potential availability of the channel. The aggregation module aggregates the set of values for the channel over the set of locations in the region to obtain a first value for the channel and determines the availability of the channel based at least in part on the first value for the channel.

  • Publication number: 20140113670
    Abstract: A method and system for obtaining an available white space channel for wireless communication using a white space device (WSD) are described. The WSD scans signals of TV transmitters, determines the received signal strength (RSSI) for those signals, and records TV data, including TV designations and corresponding RSSIs, for signals that exceed a predetermined threshold. The WSD sends TV data for at least three TV transmitters to an enhanced TV white space database (EnTVDB). The EnTVDB uses the TV data and information in its database to determine the geo-coordinates of the WSD. The EnTVDB uses the geo-coordinates of the WSD to identify available white space. The EnTVDB sends at least one channel of available white space to the white space device for its wireless communication.

In the mobile communication system, to page a UE for a first service through a primary carrier during a second service in progress through a secondary carrier, a PICH (Paging Indication Channel) transmitter in a Node B transmits paging indication information to the UE through the primary carrier by oscillating the primary carrier as a transmission frequency. A PCH (Paging Channel) transmitter transmits paging information to the UE through the primary carrier or the secondary carrier by oscillating the primary carrier or the secondary carrier as the transmission frequency under a predetermined control. A PBMSCH (Physical Broadcast Multicast Shared Channel) transmitter transmits data of the second service through the secondary carrier by oscillating the secondary carrier as the transmission frequency.
