Embodiment 1

[0045] see figure 1 , propose an energy-saving control method for a heterogeneous network according to a first embodiment of the present invention, the method includes the following steps:

[0046] S11. The macro cell sends a control instruction to the preset micro cell.

[0047] Specifically, the macro cell may issue control instructions according to preset event conditions and / or time conditions. The event conditions are when a specific event occurs, and the time conditions are when a preset time is reached (such as time cycle). Optionally, the macro cell may issue control instructions periodically, and the specific period may be set as required. Furthermore, the macro cell periodically sends control commands to the preset micro cells during the preset energy-saving time period (such as idle time), so that the control commands are issued regularly within a specific time period, which is more targeted , and reduce energy consumption.

[0048]The preset micro cells, that i...

Embodiment 2

[0078] see image 3 , propose an energy-saving control system for a heterogeneous network according to the second embodiment of the present invention, the system includes a first control module 10 and a second control module 20, and the first control module 10 and the second control module 20 can perform corresponding layout. like Figure 4 As shown, in this embodiment, the first control module 10 is set in the macro cell, and each macro cell has a first control module 10; the second control module 20 is set in the micro cell, and each micro cell has a second control module 20. Each macro cell (first control module 10) corresponds to at least one micro cell (second control module 20), and each micro cell (second control module 20) corresponds to only one macro cell (first control module 10).

[0079] In an optional embodiment, the first control module 10 and the second control module 20 can also be set independently, each first control module 10 controls at least one macro ...

Abstract

The invention discloses an energy-saving control method and system for a heterogeneous network, and belongs to the technical field of communication. The method includes the following steps: a macro cell sends a control instruction to a preset micro cell; the micro cell judges whether an energy-saving condition is met, and when the energy-saving condition is met, an energy-saving operation is performed according to the control instruction; and when the energy-saving condition is not met, the energy-saving operation is not performed according to the control instruction. Therefore, through the independent operation of the macro cell and the micro cell, the normal operation of the cooperative work of the macro cell and the micro cell can be ensured, the phenomenon that the macro cell and the micro cell do not interfere with each other can also be ensured, the unified deployment and control of the energy-saving operation can be implemented, and thus each micro cell can orderly enter or exitan energy-saving state according to the own actual situation; and the coordination and flexibility of the system can be improved, an energy-saving control process can be more orderly and efficient, an energy-saving function can be applied more reasonably and flexibly on the basis of ensuring the user experience, and the conflicts and balance between energy saving and performance and between energy saving and services can be solved.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to an energy-saving control method and system for a heterogeneous network. Background technique [0002] With the rapid development of the LTE network, the user scale and business volume have increased rapidly, and the deployment of a large number of macro base stations has also brought huge energy consumption. The huge electricity bills have brought huge cost burdens to operators. One of the most important operating expenses of operators, therefore, the demand for energy conservation and emission reduction has gradually been put on the agenda of various operators. [0003] The new-generation mobile communication network will adopt a heterogeneous network structure with overlapping coverage of macro cells and micro cells, in which the macro base station of the macro cell guarantees basic coverage to meet basic voice and data service requirements. The micro cell i...
