Method, system and equipment for counting of DRX timer

The invention relates to the technical field of wireless communication, particularly to a method, system and equipment for counting of a DRX timer, and is used for counting of the DRX timer in a dynamic TDD scene. The method in the invention includes the following steps: network side equipment determines information used for counting of a DRX timer that user equipment needs to be notified of according to a TDD configuration change situation; and the user equipment is notified of the information used for counting of the DRX timer, so that the user equipment performs counting of the DRX timer according to the information used for counting of the DRX timer. According to method for counting of the DRX timer in the embodiment of the invention, the network side equipment notifies the user equipment of the information used for counting of the DRX timer, so that the user equipment performs counting of the DRX timer according to the information used for counting of the DRX timer, thereby realizing counting of the DRX timer in the dynamic TDD scene, and improving network performance.
