Abstract

The present invention discloses a cell control method and system, and belongs to the communications field. The method includes: sending, by an RNC, indication information for deactivating a secondary cell to a second NodeB, so that the second NodeB stops, according to the indication information for deactivating the secondary cell, sending data on a downlink channel of the secondary cell; sending, by the RNC to a first NodeB, indication information for falling back a detection format, so that the first NodeB falls back, according to the indication information for falling back a detection format, to channel coding format detection of a single-cell HS-DPCCH; sending, by the second NodeB or a first NodeB, indication information for stopping channel detection of the secondary cell to a UE, so that the UE stops, according to the indication information for stopping channel detection of the secondary cell, channel detection of the secondary cell. In the present invention, activation and deactivation of a secondary cell are controlled by an RNC, a primary cell, or the secondary cell. This effectively solves a problem that a network-side HS-DPCCH and a UE-side HS-DPCCH are inconsistent in a deactivation process and an activation process and solves a problem of invalid data transmission over an interface after deactivation of the secondary cell; therefore, network-side scheduling performance is effectively improved, and power of the UE is saved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a cell control method and system. Background technique [0002] In order to further increase the peak rate, DC-HSDPA (Dual Cell High Speed ​​Downlink Packages Access, dual-cell high-speed downlink packet access) technology was introduced in UMTS (Universal Mobile Telecommunications System, Universal Mobile Communications System) R8, and HSDPA-MF-Tx was introduced in the latest UMTS standard evolution. (HighSpeedDownlinkPackagesAccessMultiFlowTx, high-speed downlink packet access downlink multi-point transmission) technology. There are multiple HSDPA serving cells in both DC-HSDPA and MF-Tx. The multiple HSDPA serving cells in DC-HSDPA must be on the same NodeB, and the multiple HSDPA serving cells in MF-Tx must be on the same NodeB. These cells can be on the same NodeB (base station) or adjacent NodeBs. From the perspective of mobility and handover, in order to better inherit ...
