  • Patent number: 10219195
    Abstract: Embodiments provide a terminal control method, a radio network controller, and a base station. The method includes: determining, by an RNC, that a downlink serving base station of a terminal that establishes a connection with both a macro base station and a micro base station is the macro base station; acquiring, by the RNC, a target power control value, where the target power control value can be used to ensure that channel quality of an uplink control channel from the terminal to the macro base station reaches a target threshold; and sending, by the RNC, the target power control value to the micro base station.

  • Patent number: 8989234
    Abstract: A method and a device for signal processing in a communication system are provided. The method includes: performing sampling and time-frequency transform on a received first time domain signal to obtain a first frequency domain signal; performing modulus operation on the first frequency domain signal with respect to a preset threshold to obtain a second frequency domain signal; performing inverse time-frequency transform on the second frequency domain signal to obtain a second time domain signal, and performing despreading on the second time domain signal. The embodiments of the present invention can avoid the problem in the prior art that not only the NBI signal but also the SS signal which is a useful signal are filtered out, which results from frequency domain signals of a certain number of frequency points being set to zero, and thereby improve the reliability of signal reception.

  • Patent number: 8817715
    Abstract: The present invention provides an improved solution of registering with a Home Agent HA of a Mobile Node MN, comprising: grouping at lest two Foreign Agents FAs to form a Foreign Agent Group FAG to enable FA members of the FAG to share information of the MN roaming into a FAG coverage area; when any FA member of the FAG receives a registration request for registering a care-of address with the HA sent by the MN, determining whether the MN enters the FAG coverage area for the first time based on the shared MN information; and if the MN enters the FAG coverage area for the first time, the FA forwards the received registration request to the HA; otherwise, the FA directly sends a registration response to the MN. The solution of the present invention greatly reduces registration messages from the MN to the HA, thereby reducing signaling delay produced when the MN moves in the FN.
