Embodiment 1

[0063] When the UE in the LTE-A system in the RRC-IDLE state camps on the default carrier (pre-configured or set the camping rules), it selects the component carrier with the best carrier quality to camp on; or according to the UE The stored and allowed component carrier is camped on, and the component carrier is used as a default component carrier, and the active time is alternately operated according to the DRX cycle broadcast on the default component carrier. When the UE initiates a call, or the UE is called, the UE and the network side will establish an RRC connection. During the connection process, the carrier of the RRC connection automatically becomes a special cell and is recorded by the network side and the UE. During the establishment process, the network side sends DRX configuration parameters to the UE. For the DRX configuration parameters, refer to the relevant description above, and will not be repeated here. After receiving the DRX configuration parameters, the ...

Embodiment 2

[0066] When the network side configures a new component carrier for the UE, the network side simultaneously indicates through RRC signaling whether to use the cell where the new component carrier is located as a special cell. If the network side still maintains the original component carrier cell, the UE will still use the SFN of the original cell as a calculation parameter for DRX. If the network side adopts a new component carrier as a special cell, the UE will use the cell SFN of the new component carrier as a calculation parameter for DRX.

[0067]When the network side configures a component carrier where a non-special cell is located for the UE, the network side simultaneously indicates whether to re-designate the new component carrier cell as a special cell through RRC signaling. If the network side still maintains the cell where the original component carrier is located, the UE will still use the SFN of the original cell as a calculation parameter for DRX. If the netwo...

Embodiment 3

[0072] When the new component carrier configured by the network side for the UE is located in another eNB, the network side simultaneously indicates whether to use the new component carrier as a special cell through RRC signaling. If the network side still maintains the cell where the original component carrier is located as a special cell, the UE will still use the SFN of the original cell as a calculation parameter for DRX. If the network side adopts the cell where the new component carrier is located as a special cell, then the UE will use the cell SFN of the new component carrier as a calculation parameter for DRX. It should be noted that even though the base stations to which the component carriers belong are different, the manner of sensing the DRX configuration parameters and the configuration of the cell carrier active time are the same.

[0073] When the network side configures a component carrier of a non-special cell for the UE, the network side simultaneously indic...

Abstract

An active time confirming method and device for discontinuous reception (DRX) in carrier aggregation system are provided. The method includes the following steps: configuration parameters of the DRX in a special cell are monitored by a user equipment, according to the configuration parameters of the DRX, the active time configuration of the component carrier, in which the special cell exists, is accomplished; the active time of the other component carriers supported by the user equipment is set as the same as the active time of the component carrier in which the special cell exists. The device includes: a monitor unit, used to monitor the configuration parameters of the DRX in the special cell; a configuration unit, used to accomplish the active time configuration of the component carrier in which the special cell exists according to the configuration parameters of the DRX; a setting unit, used to set the active time of the other component carriers supported by the user equipment as the same as the active time of the component carrier in which the special cell exists. The method and device provided by the invention are simple and practical.

Description

technical field [0001] The present invention relates to a technology for determining active time of discontinuous reception (DRX, Discontinuous Reception) of a component carrier in a carrier aggregation system, in particular to a method and device for determining active time of discontinuous reception in a carrier aggregation system. Background technique [0002] The 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) determines the Advanced Long Term Evolution (LTE-A, LTE-Advanced) system as a subsequent enhanced version of the Long Term Evolution (LTE, Long Term Evolution). The LTE-A system uses technologies such as multi-carrier aggregation, relay nodes, and coordinated multi-point receiving / transmitting. The goal is to achieve the speed requirements of uplink 500Mbit / s and downlink 1Gbit / s. Among them, carrier aggregation is the most important means to improve the transmission rate requirement. The so-called carrier aggregation means that the u...
