Problems solved by technology

[0007] The embodiment of the present invention provides a cell energy-saving method and device, which is used to solve the problem that in the prior art, the judgment of cell energy saving is too strict, and the load status of all adjacent cells needs to be detected, and one of the adjacent cells does not meet the allowable energy-saving conditions , the cell's energy-saving request is prohibited, causing the cell base station to fail to enter the energy-saving state in time, resulting in unnecessary energy consumption
[0008] The embodiment of the present invention also provides a cell wake-up method and device, which are used to solve some unnecessary base station wake-up and shutdown operations caused by using traversal to wake up the cell in the best energy-saving state when performing cell wake-up in the prior art. And the positioning accuracy and lack of accuracy of the user equipment are limited when the user equipment positioning-based method is used to wake up the best energy-saving state cell

Embodiment 1

[0141] Such as figure 2 As shown, in the embodiment of the present invention, the flow of the energy-saving judgment operation performed by the capacity layer cell is as follows:

[0142] Step 201: When it is judged that the local cell satisfies the first energy-saving decision threshold, notify the user equipment in the local cell to report a measurement report.

[0143] Specifically, the capacity layer cell may periodically perform load detection according to a preset cycle, and then judge whether the cell satisfies the first energy saving judgment threshold according to the detection result. Alternatively, the capacity layer cell can also perform load detection in a specific time period according to the cell busy / idle time period defined in advance by the Operation Administration and Maintenance (OAM), and then judge whether the cell meets the first energy-saving decision based on the detection result. threshold.

[0144] In practical applications, OAM can define the res...

Embodiment 2

[0172] Such as Figure 4 As shown, in the embodiment of the present invention, the process of waking up a cell in an energy-saving state by an overlay layer cell or a capacity layer cell that has not entered the energy-saving state is as follows:

[0173] Step 401: When it is judged that the cell satisfies the wake-up threshold of energy-saving adjacent cells, notify the adjacent cells entering the energy-saving state to send downlink detection signals.

[0174] Specifically, an overlay layer cell or a capacity layer cell that has not entered the energy-saving state can periodically perform load detection according to a preset cycle, and then judge whether the cell meets the energy-saving adjacent cell wake-up threshold according to the detection result. Or, the overlay layer cell or the capacity layer cell that does not enter the energy-saving state can also perform load detection in a specific period according to the cell busy-idle period defined by the OAM, and judge whethe...

Embodiment 3

[0200] Based on the first embodiment above, as Figure 7 As shown, taking the A4 measurement report reported by the user equipment as an example, the signaling interaction process during the energy saving decision process of the capacity layer cell is as follows:

[0201] Step 701: When the capacity layer cell judges that the cell satisfies the first energy-saving decision threshold, it notifies the user equipment in the cell to report the A4 event through an RRC Connection Reconfiguration message.

[0202] Wherein, the RRC Connection Reconfiguration message carries the a4-Threshold information element, and if the user equipment detects that the signal quality of the neighboring cell is greater than the absolute threshold a4-Threshold, it outputs an A4 measurement report.

[0203] Step 702: After receiving the RRC Connection Reconfiguration message, the user equipment in the local cell returns an RRC Connection Reconfiguration Complete message to the capacity layer cell.

Abstract

The invention discloses a cell energy saving and awakening method and device. The cell energy saving method comprises the steps that when a cell is judged to meet a first energy saving judgment threshold, user equipment of the cell is informed to report a measurement report; the measurement report reported by the user equipment is received; according to the received measurement report, candidate switching adjacent regions of the user equipment are selected, and load states of the candidate switching adjacent regions are requested; when the load states of the candidate switching adjacent regions are judged to meet a second energy saving judgment threshold, the candidate switching adjacent regions enter in the energy saving state. According to the cell energy saving method, through reporting of the measurement report, the candidate switching adjacent regions of the user equipment can be precisely positioned, and the situation that due to overloading of non-switching adjacent regions of the user equipment, a cell base station cannot execute energy saving in time is avoided.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a cell energy saving and wake-up method and device. Background technique [0002] In recent years, with the rapid development of industry, the natural environment has also been seriously damaged. With the deterioration of the environment, people are more and more aware of the importance of protecting the natural environment. In the mobile communication industry, awareness and demand for energy conservation and environmental protection are also gradually increasing. On the one hand, the sharp increase in network traffic and network applications requiring high Quality of Service (QoS) has made operators continue to increase electricity costs; on the other hand, how to set up a network with high power efficiency is reducing network energy consumption. It is also an urgent goal for operators to meet the needs of more users while meeting the needs of more users. Today, when ener...
