  • Publication number: 20130229966
    Abstract: A method for indicating discontinuous data scheduling includes receiving discontinuous reception (DRX) indication information on an Iur interface; and sending discontinuous scheduling indication information to a base station according to the DRX indication information. A communication system and a radio network control device for implementing the method are also provided.

  • Patent number: 8494545
    Abstract: The present invention discloses a method, an apparatus and a system for acquiring load information. In one method, a source access controller and a target access controller can interact through inter-Radio Access Technology (RAT) handover related messages so that a source RAT system can acquire load information of a target RAT system when an inter-RAT Packet Switched (PS) handover is performed. This enables load balancing between different RAT systems so as to guarantee communications quality of the systems. In another method of the present invention, the source access controller and the target access controller interact through a Radio Access Network (RAN) Information Management (RIM) based load information request message and an RIM based load information response message, so that the source RAT system can acquire load information of the target RAT system before an inter-RAT PS domain handover is performed.

  • Publication number: 20120294157
    Abstract: The present invention provides a method for transmitting keepalive information, a terminal, and a network device. The method includes: transmitting, by a terminal, first information to a network device, where the first information is used to instruct the network device to determine keepalive information to be received; the terminal transmits keepalive information to the network device, where the network device is configured to optimize the keepalive information. With the present invention, signaling loads are reduced.

  • Publication number: 20120082032
    Abstract: A method, apparatus, and system for triggering resource configuration are disclosed. The method includes: if user equipment (UE) in Cell_Paging Channel (Cell_PCH) state figures out that the total amount of buffer occupancy at the radio link control (RLC) layer or the Transport Channel Traffic Volume is larger than configured threshold, the UE carries an indication in a MEASUREMENT REPORT message and transmit the message to the network side, wherein the indication is used to trigger the network side to configure resources for the UE. With the present invention, the resource configuration is quickly triggered, and the delay of the UE in the data transmission is minimized.
