example 1

[0045] image 3 : A new mobile station wants to access the Internet. The nearest AN to the mobile station is AN3, but AN3 is currently closed (sleeping). Also, if AN3 is activated, mesh node MN3 must be switched on for backhaul. Another option is to connect the phone to AN2. Although this makes the power consumption of the mobile station larger, the overall power consumption may be reduced.

example 2

[0047] Figure 4 with Figure 5 :exist Figure 4 In the example shown, AN1 and AN2 are lightly loaded, while AN3 is heavily loaded. Therefore, AN1 and AN2 should be closed. If AN1 is turned off, MN1 can also be turned off, which saves most of the total energy. Figure 5 This power saving state is shown.

[0048] The problem to be solved is: How can joint optimization of access and backhaul networks be realized? In principle, a central entity (e.g., an optimization server in a network management system) could determine the optimal state of the complete network through standard optimization techniques such as simulated annealing. For example, if it is assumed that the mobile station is connected to its nearest AN, each AN is connected (only) to its nearest MN, and the mesh nodes are fully connected, then the state of the system can be described as an open network of length equal to the sum of the number of ANs and MNs / off vector. The power consumption for each possible v...

Abstract

The present invention relates to a method for energy saving in a communication system, said communication system including: at least one wireless access network comprising one or more wireless access nodes and one or more mobile stations, and at least one associated wireless backhaul network comprising one or more wireless backhaul nodes; said method comprising the steps of: controlling a first power consumption P1 of said one or more wireless access nodes, and jointly controlling a second power consumption P2 of said one or more wireless backhaul nodes such that a sum PSum of said first power consumption P1 and said second power consumption P2 is minimised. Furthermore, the invention also relates to a computer program, and a computer program product, and a control device.

Description

technical field [0001] The invention relates to an energy saving method used in a communication system. Furthermore, the invention relates to a computer program, a computer program product and a control device. Background technique [0002] Typically, traffic activity in a region is high only during short periods of the day. Nevertheless, cellular communication systems are designed for peak hour traffic. As far as traffic activity in residential areas is concerned, traffic activity is generally low when people go to work during the day, and increases again at night when people return home. For office areas, the opposite is true. [0003] In a heterogeneous network environment, different infrastructures are utilized in different ways throughout the day, for example, during office hours, macro cells provide traffic to residential areas; while in the evening and late at night, a large amount of traffic is provided by pico cells Or femtocell bearer. And at the other end of ...
