Definitions

  • the invention generally relates to enabling macro cell to femto cell handover in a communications network. More particularly, the invention relates to enablement of macro cell to femto cell handover during an active connection for a legacy user equipment connected to the network.
  • a mobile network operator may provide femto cells connected to its network, which can be used in the home or in a business and provide the advantage of improved coverage indoors.
  • a femto cell can be part of a closed subscriber group so that only a limited number of users (mobile stations) which are members of the closed subscriber group are allowed to access the network via each femto cell.
  • Each femto cell is accessible via a home Node B (HNB) and a home Node B gateway (HNB-GW) may control one or more femto cells.
  • HNB home Node B
  • HNB-GW home Node B gateway
  • a macro cell of a communications network controlled by a radio network controller may have several femto cells under its radio coverage, which are accessible via H NBs and controlled by one or more H NB-GWs.
  • the several HNBs may be controlled by one or more HNB-GWs.
  • Femto cells under radio coverage of a macro cell include having a neighbour relationship between the cells or include that the radio coverage area of macro and femto cell overlap.
  • NCL Neighbouring Cell List
  • the invention provides a method, which includes connecting to a macro cell of a communications network, sending an enquiry from a control node of the macro cell to a control node of a femto cell under coverage of the macro cell enquiring which cells under coverage of the macro cell are allowed to be accessed, and providing information regarding the cells under control of the macro cell that are allowed to be accessed.
  • sending the enquiry from the control node of the macro cell to the control node of the femto cell under coverage of the macro cell includes enquiring as to which cells controlled by the control node of the cell under control of the macro cell are allowed to be accessed by a specific user equipment connecting to the macro cell.

Abstract

L'invention concerne un procédé comportant les étapes consistant à se connecter à une macro-cellule d'un réseau de communications, à envoyer une interrogation d'un nœud de commande de la macro-cellule à un nœud de commande d'une femto-cellule située dans la couverture de la macro-cellule, demandant à quelles femto-cellules parmi celles situées dans la couverture de la macro-cellule l'accès est autorisé, et à communiquer des informations concernant les cellules situées dans la couverture de la macro-cellule auxquelles l'accès est autorisé.
