Problems solved by technology

[0011] However, the above-mentioned mechanism does not specify the conditions for starting the sleep mechanism, nor does it define how to select the parameters. If the starting conditions and parameter selection are not appropriate, it will cause unnecessary energy consumption or transmission delay, retransmission or disconnection.

Abstract

The invention discloses a sleep management method and a device thereof in a broadband wireless access communication system. In the method, a sleep mode is activated when the nearest continuous first pre-determination time data transmission intervals are all bigger than or equal to the predetermined intervals or a normal mode is activated when the nearest continuous first pre-determination time data transmission intervals are all smaller than or equal to the predetermined intervals; during the predetermined intervals, the power consumed by the user terminal in the sleep mode is bigger than or equal to that by the user terminal in the normal mode. The method and the device standardize the startup and termination of a sleep mechanism, reduce the power consumption of the user terminal as much as possible and ensure the in-time transmission of the downstream data at the same time.

Description

technical field [0001] The invention relates to a broadband wireless access communication system, in particular to a sleep management method and a sleep management device in the broadband wireless access communication system. Background technique [0002] With the increase of people's demand for broadband wireless access, relevant standards have been formulated, and related network standards are also being formulated. [0003] Broadband wireless access communication systems can support user mobility at present, and user terminal equipment is mainly handheld devices. An important factor limiting the application of handheld devices is battery life. In order to prolong the battery life, in addition to improving the battery technology, the energy management of the device itself is also an effective way. [0004] Therefore, a broadband wireless access communication system proposes a sleep mechanism and a wake-up mechanism to minimize energy consumption during idle intervals when...
