Problems solved by technology

In this way, due to the small length of the dormancy window in the quiet period, too many invalid monitoring times will be caused, and the energy loss caused by state switching and monitoring cannot be ignored, so when dormancy algorithm 2 is used, the power saving efficiency is not high, and cannot To achieve the purpose of saving electricity and energy

Embodiment 1

[0048] According to an embodiment of the present invention, a power saving control method is provided.

[0049] figure 2 is a flow chart of a power-saving control method according to an embodiment of the present invention, the method is mainly used for power-saving control of services whose length conforms to a negative exponential distribution, for example, if the length of the silent period of a voice service conforms to a negative exponential distribution, then the According to this method, the length of the sleep window of the silent period is changed, such as figure 2 As shown, the method includes the following steps (step S202 to step S204).

[0050] Step S202, the power saving mode includes at least one of the following parameters: the length of the initial sleep window, the final length of the sleep window, the change rule of the length of the sleep window, and the distribution rule of the listening window. Specifically, the parameters of the power saving mode can b...

Embodiment 2

[0064] According to an embodiment of the present invention, a power saving control method is provided, wherein the method includes: the service includes periodically alternating active periods and silent periods, wherein the active periods and the silent periods adopt different power saving modes.

[0065] Since the active period and the silent period adopt different power-saving modes, when performing power-saving management, it is necessary to switch between the active period and the silent period, or to switch the power-saving mode between the silent period and the active period. convert. Wherein, the conversion of the power saving mode may be completed through a signaling instruction, or may be completed through an implicit instruction. The implicit indication refers to: an active period indication or a silent period indication in the service corresponding coding, for example, for a voice service, the implicit indication may be an active period indication or a silent perio...

Embodiment 3

[0086] Image 6 is a flowchart of a power saving control method according to an embodiment of the present invention, such as Image 6 As shown, the method includes the following steps (step S602 to step S604).

[0087] Step S602, the power saving mode includes at least one of the following parameters: the length of the initial sleep cycle, the final length of the sleep cycle, and the change rule of the length of the sleep cycle. Specifically, the change rule of the length of the sleep cycle can be determined according to the characteristics of the service performed by the terminal. Wherein, the sleep cycle includes a listening window and a sleep window, and the length of the sleep cycle is the sum of lengths of the sleep window and the listening window.

[0088] Step S604, when entering the power-saving mode, the length of the initial sleep cycle is used as the length of the current sleep cycle, and the length of the next sleep cycle is determined according to the change rule...

Abstract

The invention discloses a power-saving control method, comprising the following steps of: determining parameters of a power-saving mode, wherein the parameters include at least one of the length of an initial dormancy window, the length of a final dormancy window, the length change law of the dormancy window and the distribution law of monitoring windows; and carrying out power saving control according to the parameters. Through the technical scheme of the invention, the mean value of delay of the service can be kept in the QoS (Quality of Service) range required by the service.

Description

technical field [0001] The invention relates to the communication field, in particular to a power saving control method. Background technique [0002] In the WiMAX standard, power saving management has been specified. In the 802.16e protocol, its media access control (Media Access Control, referred to as MAC) layer protocol defines the sleep mode operation, and the sleep mode is a mobile station (Mobile Station, referred to as MS) to a serving base station (Base Station, referred to as The dormancy window set by the BS) for a certain service that changes according to certain rules. When all services are in the dormancy window (that is, the time zone is not available), from the perspective of serving the BS, the MS has both uplink and downlink services. Unavailable, that is, in the unavailable time zone, data transmission cannot be performed between the serving BS and the MS. Through the dormant mode, the MS can turn off the transceiver device and put the control system int...
