Abstract: The present invention relates to the technical field of wireless communications, and specifically to methods, a system, and devices for configuring DRX and for monitoring a control channel. The invention is used to solve the problem in the art that in a bearer separation scenario, proper DRX cannot be immediately configured for a UE, causing the UE to conduct monitoring for a longer period of time and therefore consume additional power. The method of the embodiments of the present invention comprises: a first network-side device sending auxiliary information to a second network-side device so as to allow said second network-side device to configure DRX for the UE on the basis of said auxiliary information, wherein, after separation, part of a UE bearer is on the second network-side device. In the present invention, in a bearer separation scenario a second network-side device may configure DRX for a UE on the basis of auxiliary information. This accelerates configuration of proper DRX for a UE, which shortens the amount of time the UE conducts monitoring and reduces UE power consumption.

Abstract: The present invention relates to DRX technology and disclosed are a method and device for computing an activation time, which are used for solving the problem that a UE cannot enter an active state at an accurate time when using an extended DRX cycle. The method is: a network side notifying a UE of a serial number of a current SFN cycle in an extended DRX cycle, and the UE computing an activation time of the UE by combining the length of a preset extended DRX cycle in accordance with the serial number. In this way, when the extended DRX cycle is greater than the SFN cycle, the UE can still compute a correct paging time and/or a time of receiving service data, thereby entering the active state at an accurate time, effectively avoiding the situation where paging messages or service data are lost due to computation errors of the UE, then guaranteeing the service QoS of the UE and improving the service performance of the system.

Abstract: The embodiments of this application relate to the field of wireless communications. Disclosed are an auxiliary information reporting and information sending method and device, so that a target base station can acquire the latest auxiliary information of a user equipment (UE) and then can provide the most reasonable configuration for the UE. In this application, the UE reports the auxiliary information to a source base station, and determines whether it is required to re-report the auxiliary information in a target cell; if determining that it is required to re-report the auxiliary information in the target cell, the user equipment reports the auxiliary information to the target base station after being switched to the target cell. It can be seen that, in this solution, the target base station can acquire the latest auxiliary information of the UE, so as to provide the most reasonable configuration for the UE.
