20150229590 | METHOD, SERVER, CLIENT, AND SYSTEM FOR RELEASING INSTANT MESSAGING KEY-VALUE DATA - Methods, servers, clients, and systems for releasing instant messaging key-value data are provided. A server receives a request packet for pulling key-value data sent from a client during a login. The request packet at least contains a full-amount pulling time-stamp, an increased-amount pulling time-stamp, and a data-altering serial number. The server selects a pre-set data releasing mechanism according to parameters contained in the request packet, to release full amount key-value data to the client or to release increased amount key-value data to the client, or not to release the key-value data, such that, according to a returned result from the server, the client updates local cache data to display to a user. | 08-13-2015 |

20130128840 | Method and Base Station for Dynamic Adjustment of Carrier Resource - A method and base station for dynamic adjustment of a carrier resource are disclosed. First, a cell-edge traffic volume of a local cell is detected; then, if the cell-edge traffic volume of the local cell is reduced, an idle primary subcarrier resource in the cell is released as a secondary subcarrier according to a degree of reduction of the cell-edge traffic volume and according to a multiple of a predetermined minimum granularity. With it, when the cell-edge traffic volume of the local cell is changed, the allocation of a primary subcarrier and a secondary subcarrier may be adjusted dynamically, which increases a utilization rate of a spectrum and ensures that carrier resources can be utilized properly and adequately. | 05-23-2013 |
20130129004 | DATA MODULATION AND DEMODULATION METHOD, SPECTRUM MANAGEMENT METHOD, APPARATUS AND SYSTEM - A data modulation method, a data demodulation method, and a method, include obtaining a target frequency band allocated to a transmitting terminal; calculating a precoding codeword index of spectrum shaping according to a codebook corresponding to a current radio scene and the target frequency band, where the codeword index corresponds to a return-to-zero subcarrier sequence, and the return-to-zero subcarrier sequence serves to calculate a precoding vector for modulating data; and sending the precoding codeword index out through broadcast. | 05-23-2013 |
20130308726 | METHOD AND APPARATUS FOR SENDING SIGNALS - Embodiments of the present invention disclose a method and an apparatus for sending signals to suppress outband interference effectively in a simple way. The method of the present invention includes: grouping subcarriers in a spectrum into edge subcarriers of the spectrum and non-edge subcarriers of the spectrum; precoding data to be sent to obtain modulated symbols of the data on the subcarriers, where the precoding makes every two adjacent edge subcarriers of the spectrum in the edge subcarriers of the spectrum carry a pair of modulated symbols with opposite polarities, and makes each of the non-edge subcarriers of the spectrum carry a modulated symbol with no polarity; and sending the modulated symbols of the data on the subcarriers. The embodiments of the present invention are applicable to a signal sending process. | 11-21-2013 |
20140171095 | METHOD FOR REDUCING INTER-FEMTOCELL INTERFERENCE AND FEMTOCELL BASE STATION - The present invention discloses a method for reducing inter-Femtocell interference, including: obtaining an average channel gain of all available channels; determining whether the average channel gain is greater than a preset threshold; if the average channel gain is greater than the preset threshold, determining, by using spectrum sensing, a P channel and an N channel, where the P channel is one or more available channels causing greatest interference and the N channel is one or more available channels suffering greatest interference; and transmitting or receiving a signal in an available channel other than the P channel and the N channel. | 06-19-2014 |

20160132443 | TRACKING VIRTUAL MACHINE MEMORY MODIFIED BY A SINGLE ROOT I/O VIRTUALIZATION (SR-IOV) DEVICE - Techniques for tracking, by a host system, virtual machine (VM) memory modified by a physical input/output (I/O) device that supports I/O virtualization are provided. In one embodiment, a hypervisor of the host system can receive a hardware interrupt from the physical I/O device, where the hardware interrupt indicates that a virtual function (VF) of the physical I/O device has completed a direct memory access (DMA) write to a guest memory space of a VM running on the host system. In response to the hardware interrupt, the hypervisor can invoke a function implemented by a physical function (PF) driver of the physical I/O device, where the function is configured to inspect the VF's state in order to identify memory portions modified by the DMA write. The hypervisor can then mark, in a hypervisor-level page table, one or more memory pages corresponding to the identified memory portions as dirty pages. | 05-12-2016 |
