Embodiment Construction

[0035] The principles of the invention will be described more fully hereinafter with reference to the accompanying drawings, in which specific embodiments of the principles of the invention are shown. However, the inventive principles may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided by way of example so that this disclosure will be thorough and complete and will fully convey the scope of the principles of the invention to those skilled in the art. In this specification, the same reference numerals refer to the same elements.

[0036] figure 1 A schematic overview of an exemplary wireless communication system 1 is shown. The wireless communication system 1 comprises network nodes 2a, 2b providing network coverage over cells (not shown). Each cell is served by at least one of the network nodes 2a-b. Thus, a user equipment (UE) 5 located in a particular cell is provided w...

Abstract

A load sharing performed by a first processing unit device and a second processing unit device is provided. The load sharing is implemented by the first processing unit device determining different subsets of UEs from the set of user equipment UEs, wherein the UEs in the different subsets of UEs are candidates for load sharing. information identifying the UEs in the different subset in which the different subset of UEs are served, and information about the load of the first cell and information about the load of the second cell are transmitted to the second processing unit device, The second cell is a candidate cell for serving a different subset of UEs. Based on the evaluation of the information received from the first processing element device, the second processing element device determines a load sharing action for use by the first processing element device.

Description

technical field [0001] Embodiments presented herein relate to cellular networks, and in particular to methods, network nodes and computer programs for load sharing in cellular networks. Background technique [0002] In cellular networks, there are always challenges in achieving good performance and capacity for a given communication protocol, its parameters, and the physical environment in which the cellular network is deployed. [0003] In cellular networks where users in cells are served by network nodes, there may be areas of high traffic, ie areas of high concentration of users. User here means wireless user equipment, such as user equipment UE. In these areas, it is desirable to deploy additional capacity to ensure user satisfaction. The added capacity may be in the form of additional macro network nodes or network nodes with lower output power, such as micro or pico network nodes covering a particular area, thereby concentrating the capacity increase on a particular ...
