Abstract

The embodiment of the invention discloses a control method, control equipment and a mobile communication system of an auxiliary carrier. The method comprises the following steps of determining whether an auxiliary carrier de-activating condition of a preset mobile terminal is satisfied or not according to any one of a service cell resource, the service volume of the mobile terminal and the coverage state of the mobile terminal; and if the auxiliary carrier de-activating condition of the mobile terminal is satisfied, controlling the uplink auxiliary carrier of the de-activating mobile terminal. By the control method, the control equipment and the mobile communication system, adaptive activation and de-activation of the auxiliary carrier can be relatively and flexibly realized, the carrier resource of the system is optimized, the volume loss of the system is relatively well reduced, the uplink and downlink throughput of the user can be relatively well reduced, and time delay is reduced.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method for controlling a secondary carrier, a control device and a mobile communication system. Background technique [0002] With the rapid development of wireless network data services, users' demand for uplink and downlink data services is getting higher and higher. In the third generation mobile communication partnership project (3GPP), HSUPA (High Speed ​​Uplink Access, High Speed ​​Uplink Access) was introduced. ), realize the uplink high-speed data transmission, and introduce HSDPA (High Speed ​​Downlink Packet Access, high-speed downlink packet access) to realize the downlink high-speed data transmission. [0003] For HSUPA and HSDPA, currently only the main carrier and the optional auxiliary carrier are defined for uplink and downlink data transmission, and the deactivation trigger method of the auxiliary carrier is not defined. How to realize the adaptive d...
