Embodiment 1

[0052] Embodiment 1: Map the greenness information to the corresponding handover decision parameter at the green base station

[0053] In this embodiment, the handover decision parameter is modified according to the greenness information, so as to realize the adjustment of the cell coverage, such as increasing the cell coverage of the green base station.

[0054] image 3 A flowchart of the configuration method of the wireless communication system in this embodiment is shown. See image 3 , The method includes:

[0055] In step 301, the greenness information corresponding to the base station is determined in advance according to the carbon emissions of the base station.

[0056] In this step, each base station itself can determine its own greenness information according to one or more preset indicators reflecting carbon emissions. Specifically, indicators reflecting carbon emissions may include: the energy type of the base station, the refrigeration status of the base station, the en...

Embodiment 2

[0078] Embodiment 2: When the green base station is the target base station, the greenness information is mapped to the corresponding handover decision parameter at the serving base station

[0079] In this embodiment, the handover decision parameter is also modified according to the greenness information, so that when the user terminal is located at the edge of the coverage of the green base station, it is easier to cut into the green base station. It can be seen that this embodiment realizes the adjustment of the cell coverage, and more user terminals can access the green base station earlier, thus making the entire system more energy-efficient. The difference between this embodiment and Embodiment 1 is that the mapping of the handover decision parameter is completed in the serving base station of the neighboring cell of the green base station.

[0080] Figure 5 A flowchart of the configuration method of the wireless communication system in this embodiment is shown. See Figure...

Embodiment 3

[0094] Embodiment 3: Perform mapping on the user terminal, and map the greenness information to the corresponding handover decision parameter

[0095] The configuration process of the wireless communication system in this embodiment is similar to that in Embodiment 1. The difference is that the green base station does not need to map the greenness information to the corresponding handover decision parameter, and then sends the mapped handover decision parameter to the serving base station and / or user terminal of the neighbor cell, but directly sends the greenness information to User terminal.

[0096] According to the obtained greenness information, the user terminal adjusts Ocn1 to increase, or Ocs1 to decrease, or a combination of the above two conditions, and switches to the green base station according to the mapped Ocn1 and / or Ocs1.

[0097] Or, the user terminal adjusts Ocn2 to lower or raises Ocs2 according to the obtained greenness information, or a combination of the above ...

Abstract

PROBLEM TO BE SOLVED: To provide a setting method for a wireless communication system that facilitates more frequent use of a green base station in a wireless communication system, and to provide a base station and a wireless communication system.SOLUTION: A method includes the following steps of: acquiring green degree information for the self station by one or more base stations in a wireless communication system; mapping the green degree information to a corresponding base station setting parameter after a green base station is decided, based on the green degree information; and carrying out setting to the wireless communication system based on the mapped base station setting parameter. By the method, the green base station in the wireless communication system can be used more frequently. Thereby, energy saving and emission reduction in the whole system can be realized further.

Description

Technical field [0001] The present invention relates to the field of wireless communication, in particular to a configuration method of a wireless communication system, a base station and a wireless communication system. Background technique [0002] With the development of communication technology, there are more and more entities in the wireless communication system (such as communication equipment such as base stations and user terminals), and the amount of information transmitted between entities is also increasing. Then the operation of these entities themselves The energy consumption caused by the information exchange between entities is also increasing day by day. Data shows that the cost of energy consumption by operators accounts for a considerable proportion of their total operating costs. [0003] In the total energy consumption of the entire system, the energy consumption of the base station takes a large proportion. Take the cellular network as an example. During the...
