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: 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 User Equipment (UE), a method for determining a resource, a method for reporting a resource, and a system for distributing a resource are provided. The method for determining a resource includes: if transmission data on the carrier reaches maximum transmission data supported in a scope allowed by Service Grant (SG), and a transmission power of the UE is capable of improving a data transmission rate of the carrier, and the carrier and the other one carrier of the dual carriers are incapable of completing transmitting total buffer status data in the same delay period, determining that a resource distributed to a UE on one carrier of dual carriers of the UE is insufficient; otherwise, determining that the resource distributed for the UE on the carrier is sufficient. Therefore, a solution for reporting the resource of the dual carriers is provided, so as to improve a network performance.
