Abstract: A method for configuring an accelerator, applied to a server including at least one bare accelerator. The at least one bare accelerator is an accelerator that is generated after a basic logic function is loaded for accelerator hardware, and the basic logic function includes a communications interface function and a loading function. The method includes determining, by the server, a target service type and a target bare accelerator, determining, by the server, a service logic function corresponding to the target service type, and loading, by the server, the service logic function corresponding to the target service type for the target bare accelerator to generate a target service accelerator, where the target service accelerator is capable of providing an acceleration service for a service of the target service type.

Abstract: A data packet transmission method and a border routing bridge device, where the method includes receiving, by a first border routing bridge device of a first area, a first data packet sent by a border routing bridge device of a second area to the first area, determining, a device identifier group of the second area according to the first data packet, determining, from the device identifier group of the second area, according to the first data packet, a device identifier of a border routing bridge device used to forward a return data packet sent by the target device to the source device, and sending, by the first border routing bridge device, a second data packet carrying the determined device identifier to the target device, where the determined device identifier is used as a source routing bridge device identifier of the second data packet.

Abstract: In a system for controlling a radio base station, an out-of-band emergency channel based on a power cable is established between a BBU and an RRU, so that even if a unique communications interface CPRI between the BBU and the RRU is abnormal, the BBU can still effectively control the RRU using the out-of-band emergency channel. In another system for controlling a radio base station, out-of-band emergency channels based on power cables are established among multiple RRUs, so that even if a unique communications interface CPRI between a BBU and a target RRU is abnormal, the BBU can still effectively control the target RRU using an out-of-band emergency channel between any RRU (a unique communications interface CPRI of the RRU is normal) and the target RRU. In the present disclosure, the BBU can effectively control the RRU.

Abstract: Systems, devices and methods for link level communication between a user equipment and plurality of network devices are described. A user equipment can include at least one processor configured to: after broadcasting a first data message to the plurality of base stations, receive one or more acknowledgements, corresponding to the first data message, from at least one of the plurality of base stations; and upon receipt of at least one acknowledgement, broadcast an indicator to the plurality of base stations, the indicator providing an indication of at least one of the at least one received acknowledgement.

Abstract: Embodiments are provided for an improved 2×1 switch cell design with integrated photodiode for off-state monitoring. In an embodiment, am optical switch comprises a 2×1 multi-mode interferometer (MMI) coupler including two input waveguides jointly coupled to an output waveguide, and a photodetector coupled to an edge of a first waveguide of the input waveguides, and positioned next to a side of the output waveguide. In another embodiment, an optical chip comprises two input waveguides parallel to each other, and an output waveguide coupled to the two input waveguides. The optical chip further includes a photodetector coupled to a first waveguide of the two input waveguides, and positioned next to the output waveguide, and a branch waveguide extending from the first waveguide into the photodetector.

Abstract: An apparatus and method for reducing effects of spurs in a phased-locked loop having a sigma-delta modulator and digital circuits. The apparatus includes a clock dithering circuit coupled to each of the sigma-delta modulator and the digital circuits. Each clock dithering circuit is configured to dither flanks of a respective first and second clock input signal, and generate a dithered clock output signal, one for each of the sigma-delta modulator and digital circuits. A frequency of each dithered clock output signal follows a frequency of the respective first and second clock input signals, and a phase between each dithered clock output signal and the respective first and second clock input signal is shifted and constantly changing.

Abstract: The present invention discloses a multimedia message system, which includes: aSP; a Multimedia Message Service Center (MMSC), which is configured to receive, store and send multimedia messages; and a Multimedia Message Service Gateway (MMSG) connecting with at least one MMSC and the SP belonging to the MMSG respectively, which serves to authenticate the SP and a user in the multimedia message and a provided service, and to send the multimedia messages from the SP or the MMSC. And the present invention provides three methods for sending multimedia messages. The system and methods provided by the present invention can lower the load of the MMSC and enhance the security of the MMSC.

Abstract: Embodiments of the present invention provide a data transmission method and apparatus. ROHC packets that use a same Context ID are encapsulated into MAC PDU, wherein the MAC PDU is formed by a MAC PDU packet header and a MAC PDU payload. The Context ID of the ROHC packets is carried in the MAC PDU packet header, and the Context ID is not carried in the ROHC packets. The MAC PDU is sent. In this way, transmission resources are saved, and transmission efficiency is improved.

Abstract: A method for changing ICS session media includes: receiving a media type change request including a new media type sent from a terminal equipment or a MSC, releasing a CS call leg based on an original media type between an ICCF and the terminal equipment, establishing a CS call leg based on the new media type between the ICCF and the terminal equipment, and updating a media type of a second call leg between the ICCF and a second party into the new media type; or, receiving a media type change request including a new media type sent from a second party, updating a media type of a second call leg between an ICCF and the second party into the new media type, releasing a CS call leg based on an original media type between the ICCF and a terminal equipment, and establishing a CS call leg based on the new media type between the ICCF and the terminal equipment.
