Problems solved by technology

[0005] The UE needs to frequently migrate between the CELL_FACH state and the CELL_PCH state, and the UE needs to perform a large number of signaling interactions with the network during each migration, consuming a large amount of network resources

Embodiment 9

[0145] 901: When the UE enters the CELL-FACH state, receive the first DRX cycle length, the first DRX-on length (the length of the receiver in the first DRX cycle) or the first DRX-off length (the first DRX cycle length) sent by the network side length of the receiver off in a DRX cycle), and the inactivity timer.

[0146] Specifically, these parameters are notified by the RNC to the UE through system messages or dedicated signaling; the first DRX cycle length is equal to the sum of the first DRX-on length and the first DRX-off length; the first DRX cycle length is used to determine the discontinuous The length of the receiving cycle, the first DRX-On is used to determine the length of time that the receiver is turned on to receive downlink data in the discontinuous reception cycle, and the first DRX-off is used to determine the time when the receiver is turned off and does not receive downlink data in the discontinuous reception cycle Length; the static state timer is used to...

Abstract

The invention discloses a CELL-FACH state power-saving method, equipment and system, belonging to the field of communication. The method comprises the following steps of: when user equipment (UE) is transferred to a CELL-FACH state of a cell forward access channel, receiving a DRX (discontinuous reception) parameter of a first DRX cycle, which is sent from a base station; acquiring the time of notification of the first DRX cycle according to an identification code of the UE and / or the DRX parameter of the first DRX cycle; performing DRX according to the first DRX cycle; and when a notice of the base station is monitored at the time of notification of the first DRX cycle, receiving downlink data which is sent from the base station to the UE. According to the method disclosed by the invention, the UE can be prevented from being transferred between the CELL-FACH state and a CELL-PCH state, a large number of signals caused by transfer can be avoided, and network resources can be further saved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for saving electricity in a CELL_FACH (CELL_Forward Access Channel) state. Background technique [0002] The CELL_FACH state is the normal state of the smart UE. When the UE (User Equipment, user equipment) is in the CELL_FACH state, it can receive downlink data discontinuously. That is, when there is downlink data, the UE turns on the receiver to receive the downlink data. When there is no downlink data, the UE Turn off the receiver to save power. [0003] Among them, the CELL_FACH state consumes more power than the CELL_PCH (CELL_Paging Channel) state. In order to further save power, when the UE is in the CELL_FACH state, if the UE has no uplink data to send, the network will migrate the UE to the CELL_PCH state; when the UE migrates to the CELL_PCH state, if the UE has uplink data to send, the network will The UE transitions to the CELL_FACH stat...
