Embodiment Construction

[0027] exist figure 1 , schematically shows a schematic diagram of a situation in a wireless network in which different embodiments of the present invention can be applied.

[0028] Here, three access points AP1 , AP2 and AP3 are shown via which terminals can be connected wirelessly to network 100 . In this case, they can generally be any desired access points; in particular, these wireless access points can also be base stations of the mobile radio network, ie, for example, Node Bs. Via these access points, suitable terminals can communicate with the real (eigentlich) network or core network (core network). Intermediate network elements between the access points AP1 , AP2 , AP3 and the network 100 , such as switching centers (Vermittlungsstelle), controllers, etc., have been omitted here for the sake of simplicity, wherein these intermediate network elements can in turn be dependent on Differently configured depending on the network.

[0029] Each wireless access point can...

Abstract

The invention relates to a method for load balancing in a communication network, the method comprising: determining (310) a load level of a first access point (AP1) of said communication network at least based on parameters of a service provided by an access point to terminal devices (D1, D2, D3); and if the load level of the first access point (AP1) exceeds a predefined first threshold value (320), preparing (350, 360) to hand over at least one service to a second access point of one or more neighboring access points (AP2, AP3), wherein the coverage area (120, 130) of the adjacent access point (AP2, AP3) at least partially overlaps the coverage area (110) of the first access point (AP1) so as to form an overlapping area (140).

Description

technical field [0001] The invention relates to a method for load balancing in a communication network and to a computer program product and a computing unit for carrying out the method. Background technique [0002] A wireless network usually includes a plurality of access points (zugangspunkt) over a large area, wherein terminals gain access to the network via these access points. This can be, for example, a WLAN network or also a mobile radio network, which is based, for example, on the LTE or 5G standard. Since each access point has only a limited capacity (Kapazität), e.g. with respect to the bandwidth offered for these connections, situations may arise in which the access point reaches its maximum capacity and is no longer able to Accept additional connection or service requests. This can result, for example, in that a device newly arriving in the corresponding area cannot establish a connection or that the connection is interrupted. [0003] Each access point has a...
