Control unit and method for controlling the load in a mobile telecommunications network

摘要

A method and control nodes for controlling load-based handover in a mobile telecommunications network is proposed and at least one logical control node for controlling resources in said cell and at least one logical service node for controlling quality of service, wherein said logical service node comprises terminal instruction means for instructing a mobile terminal communicating with said at least first base station to perform a handover, comprising the steps of—determining, in the CRNC, if the load in the cell exceeds a first threshold,—selecting, in the CRNC, a mobile terminal that should be moved to another carrier if the load in the cell exceeds the first threshold, and—instructing, from the CRNC, the SRNC to instruct the at least one mobile terminal to perform a handover.

主权项

1. A logical control node for use in a mobile telecommunications network for controlling at least a first base station serving a first cell, said logical control node comprising:
a processor; and a memory, said memory containing instructions executable by said processor, whereby said logical control node is operative to:
determine if a load in the first cell exceeds a first threshold,select at least one mobile terminal communicating with the at least first base station which should be moved to another carrier if the load in the first cell exceeds the first threshold, the selection based on a traffic class between the at least first base station and the at least one mobile terminal in combination with a service indicator received over an lur interface from a logical service node; andinstruct, over the lur interface, the logical service node to instruct the at least one mobile terminal to perform a handover to the another carrier;wherein the traffic class comprises one of:
conversational traffic;streaming traffic;interactive traffic; orbackground traffic.
