    • A method of device management relating to communication technology, wherein the method comprises the following steps of: the device initiatively sending a IP packet for management registration request to a management system according to address information of the management system, the request packet at least comprising the unique device identifier and IP address of the device; after the management system receiving registration request of the device, judging whether this device is legal or not according the unique device identifier, if it is, accepting the registration, otherwise rejecting. Dynamic configuration of the device can be performed through standard DHCP (Dynamic Host Configuration Protocol) procedure; encryption manner can be adopted for the IP packet for management registration request and its response packet; the device sends the management registration packets to management system at every internal; the present invention is of low maintenance cost, high efficiency, and high network management system security, avoiding illegal and forged devices from accessing.
    • 一种与通信技术有关的设备管理方法,其特征在于,该方法包括以下步骤:设备根据管理系统的地址信息主动地向管理系统发送用于管理注册请求的IP分组,该请求分组至少包括 设备的唯一设备标识符和IP地址; 在管理系统接收到设备的注册请求后,根据唯一的设备标识符判断该设备是否合法,否则接受注册,否则拒绝。 可以通过标准DHCP(动态主机配置协议)程序来执行设备的动态配置; 用于管理注册请求的IP包及其响应包可以采用加密方式; 该设备每个内部向管理系统发送管理注册报文; 本发明维护成本低,效率高,网络管理系统安全性高,避免了非法和伪造设备的访问。

    • A method for allocating downlink transmission power of coordinated transmission devices in coordinated multi-point transmission system includes the coordinated transmission devices receiving feedback of channel state information of sub-channels occupied by a terminal from the terminal. The channel state information includes channel phase information and channel amplitude information. Each of the coordinated transmission devices adjusts phases of their sending signals over its sub-channels respectively so as to make phase difference of the sending signals, which are received by the terminal from the coordinated transmission devices via a same sub-channel, to be minimal. Each of the coordinated transmission devices determines its power allocation proportions for the sub-channels on the basis of feedback of channel amplitude information from the terminal and the adjusted phases of the sending signals. By adapting coordinate Iterative Water filling Power Allocation Algorithm with low complexity, the capacity of the system is increased.
    • 在协调多点传输系统中分配协同传输设备的下行传输功率的方法包括:从终端接收终端占用的子信道的信道状态信息反馈的协调传输设备。 信道状态信息包括信道相位信息和信道幅度信息。 每个协调传输设备分别通过其子信道调整其发送信号的相位,以便使终端从协同传输设备经由相同子信道接收的发送信号的相位差最小化 。 每个协调传输设备基于来自终端的信道幅度信息的反馈和发送信号的经调整的相位来确定其子信道的功率分配比例。 通过适应复杂度较低的坐标迭代注水功率分配算法,提高了系统的容量。
