  • Apparatus and method for clock generation
    Patent number: 9749125
    Abstract: A clock and data recovery (CDR) system may use one or more clock signals in sync with recovered data rate. By accumulating a dithering tuning counter value at a data oversampling rate, a plurality of single bit signals at multiples of the recovered data rate and in sync with the recovered data rate can be accurately generated while utilizing the full range of the accumulator. This plurality of clock signals can be used in various modules in the CDR system and other modules in a transceiver system incorporating the CDR system.

  • Dialing method and device
    Patent number: 9742911
    Abstract: A dialing method for a calling party includes determining a plurality of phone number groups to be dialed in a simultaneous or sequential ringing mode, each of the groups including at least one phone number; and transmitting the plurality of phone number groups and a dialing flag to a calling server. The dialing flag including a simultaneous or sequential ringing flag indicating that the plurality of phone number groups are to be dialed in the simultaneous or sequential ringing mode. The calling party can freely custom multiple phone numbers expected to be rung simultaneously or sequentially and transmit them to a calling server, without registering in the calling server in advance. Thus, the trouble of the user registering the numbers in the calling server may be avoided and the calling server does not need to maintain a large-scale database for storing the multiple numbers at a large cost.

  • Paging method and device
    Patent number: 9622212
    Abstract: A paging method includes, when needing to page a user equipment (UE) according to service requirements, a mobile switching center (MSC) analyzing a user identification if finding that subscriber data are lost at present, judging whether the UE has a possibility of residing in a long term evolution (LTE) network, if yes, finding out one or more mobility management entities (MMEs) which are overlapped with the coverage area of the MSC itself, and sending a paging message for the UE to the MMEs. An MSC includes a first module, a second module, a third module and a fourth module. With the paging method and apparatus provided, the UE in the LTE can be successfully paged under the condition that a visitor location register (VLR) loses the subscriber data and a home location register (HLR) fails to return an MME identification.

  • Local cell discovery in macro-assisted enhanced local area
    Patent number: 9596644
    Abstract: A macro eNB (MeNB) triggers a small cell (eLA eNB) to transmit a sequence on a second frequency band using a triggering command that indicates a time to transmit the sequence. On a first frequency band the MeNB triggers at least one user equipment UE to detect the sequence on the second band, and this trigger also has a first indication of when the sequence will be transmitted. From a second indication the MeNB receives on the first band from the at least one UE in response to the triggering of the UE the MeNB can determine whether the UE is located proximate to the small cell. The indication may be as little as a single bit indicating whether the UE detected or not the sequence. The first and second bands may be on first and second component carriers that may not be synchronized to one another, and the aperiodic nature of the triggered sequences and detection reports saves UE power.

  • Power line network apparatus, system and method
    Patent number: 9590698
    Abstract: Various aspects of the instant disclosure are directed towards a method for communicating time-based data in a power line communication system. In accordance with one or more example embodiments, firmware is downloaded to a multitude of endpoints over power distribution lines carrying alternating current (AC) power. Endpoint devices targeted for changes to stored firmware are grouped and the firmware is delivered in chunks to each group. As devices receive a particular chunk of firmware, the device advances to a next stage and provides information indicative of this stage, based upon which subsequent chunks of firmware are communicated. This occurs (e.g., on a daily cycle) until the endpoint has received all firmware for an update, after which the endpoint(s) are re-started using the firmware. Accordingly, such updates can be carried out in a cyclic and verifiable manner.
