20120064896 | METHOD, APPARATUS, AND SYSTEM FOR ACQUIRING LOAD INFORMATION - 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. | 03-15-2012 |
20130230022 | METHOD AND DEVICE FOR SWITCHING OF MULTI-CARRIER - A method for switching of multi-carrier and device are provided. The method comprises: receiving a message sent from a source RAN node corresponding to a first link and comprising information of a second link; according to the information of the second link, establishing a connection between a target RAN node corresponding to the first link and an RAN node corresponding to the second link, so as to perform data transmission. The first link is a link in a first Radio Access Technology (RAT) network, and the second link is a link in a second RAT network. Embodiments of the present invention can ensure the continuity of the throughput of data transmission during switching under aggregation of multiple RAT carriers. | 09-05-2013 |
20130250883 | Method and Apparatus for Paging User Equipment in Cell_PCH State - Embodiments of the present invention disclose a method and an apparatus for paging a user equipment in a Cell_PCH state and relate to the field of communication technologies. When a UE in a Cell_PCH state is paged by a network, congestion of HS-SCCH resources is reduced and an access delay of the UE is decreased. For example, a radio network controller instructs a base station to send data to a user equipment via a high speed physical downlink shared channel (HS-PDSCH). The user equipment is in a Cell_PCH state and has a dedicated radio network temporary identity (H-RNTI). | 09-26-2013 |
20130294379 | METHOD AND DEVICE FOR PROCESSING SERVICE DATA STREAM - Disclosed are a method and a device for processing a service data stream. The method includes: a Media Access Control (MAC) layer transmitting data to a physical (PHY) layer; and the MAC layer notifying the PHY layer to process different data substreams by using different processing modes. The present invention is capable of saving network resources, increasing the number of access users and reducing the interference therebetween. | 11-07-2013 |
20140056376 | TRANSMISSION METHOD, APPARATUS, AND SYSTEM BASED ON UPLINK TRANSMIT DIVERSITY - A transmission method, apparatus, and system based on uplink transmit diversity, relating to the field of communications are provided. To timely and efficiently determine to activate or deactivate uplink transmit diversity and improve uplink transmission quality, a base station sends an activation request instruction to a radio network controller when determining, according to relevant reference measurement value(s) of a user equipment, to activate uplink transmit diversity of the user equipment; and the radio network controller notifies, according to the activation request instruction, the user equipment of activating the uplink transmit diversity; or a base station sends a deactivation request instruction to a radio network controller when determining, according to relevant reference measurement value(s) of a user equipment, to deactivate uplink transmit diversity of the user equipment; and the radio network controller notifies, according to the deactivation request instruction, the user equipment of deactivating the uplink transmit diversity. | 02-27-2014 |
20140066051 | ENERGY-SAVING CONTROL METHOD AND DEVICE FOR CELL IN HETEROGENEOUS SYSTEM - The present invention provides an energy-saving control method for a cell in a heterogeneous system, including: receiving, by an access control device of a serving cell, a service request of a multi-mode user equipment UE; and when a radio resource of the serving cell cannot satisfy the service request of the multi-mode UE, if the access control device of the serving cell determines that a heterogeneous-system neighboring cell of the serving cell is in an energy-saving state, sending, by the access control device of the serving cell, an exit energy-saving state request message to an access control device of the heterogeneous-system neighboring cell, where the exit energy-saving state request message is used to request the heterogeneous-system neighboring cell to exit the energy-saving state. The technical solution implements energy-saving control for a cell in a heterogeneous system. | 03-06-2014 |
20140080422 | TRANSMISSION METHOD, APPARATUS, AND SYSTEM FOR UPLINK TRANSMIT DIVERSITY - Embodiments of the present invention disclose a transmission method, apparatus, and system for uplink transmit diversity, which relate to the field of communications. To determine activation or deactivation of uplink transmit diversity in time and effectively to improve uplink transmission quality, the technical solution provided in the present invention is as follows: determining, by a base station, to activate/deactivate uplink transmit diversity of a user equipment and sending an activation/deactivate request indication to a radio network controller, the activation/deactivate request indication is used for the radio network controller to instruct the user equipment to activate/deactivate the uplink transmit diversity. The present invention is applicable to the control of uplink transmit diversity transmission. | 03-20-2014 |
