  • Reconfiguration of a mobile telecommunications network element
    Patent number: 7260397
    Abstract: The present invention discloses a method and a system for reconfiguring a mobile telecommunications network. In the method network elements to be reconfigured are arranged into groups according to a grouping parameter. A priority value is assigned to the groups. The network elements are reconfigured by groups in an order indicated by the assigned priority value. For example cells in the mobile telecommunications network are reconfigured in an order indicated by the priority value so that the entire network is not updated concurrently. Typically the priority values are assigned so that adjacent cells do not share the same priority value thus existing connections can be handed over to adjacent cells so that the services do not have any breaks.
