Handling location information for femto cells
First Claim
1. A method for a Home eNode B (HeNB) of a mobile telecommunication network, wherein the HeNB is connectable to a core network node of the mobile telecommunication network and is adapted to serve at least one femto cell and the HeNB is further connectable to a set of user equipment (UE) being authorized to connect to the HeNB, the method comprises the steps of:
- retrieving Femto Cell Location Information indicative of a location of the HeNB;
sending the retrieved Femto Cell Location Information to the core network node for forwarding the Femto Cell Location Information to a UE authorized to connect to the HeNB, wherein the UE determines whether the UE is within or close to a coverage of the HeNB based on a location of the UE determined by the UE;
receiving information, from the core network node, that the HeNB should either be switched off or switched on; and
switching the HeNB off or on, according to the information received from the core network node.

Abstract
The present invention relates to methods and arrangements for configuring the HeNB (Home eNode B) to retrieve location information indicative of its location and sending this location information via a core network node to a UE (User Equipment) authorized to access the HeNB. The UE can then based on this received location information and on a determination of the location of the UE determine whether the UE is being positioned in the coverage of the HeNB. This implies that the authorized UEs of the HeNB know when they should try to find and access the HeNB and the UEs may then avoid accessing the HeNB when it is out of the HeNB coverage which will save UE battery and reduce interference.

6. A method for a user equipment (UE) authorized to be connected to a Home eNode B (HeNB) of a mobile telecommunication network, wherein the HeNB serves at least one femto cell, the method comprises the steps of:
-
receiving Femto Cell Location Information indicative of a location of the HeNB; determining a location of the UE; determining whether the location of the UE is within a range in relation to the location of the HeNB; performing an access attempt if the location of the UE is within the range in relation to the location of the HeNB; sending a message to the HeNB via a currently connected eNode B and a core network node to switch on the HeNB, and then performing an access attempt, if the location of the UE is within the range in relation to the location of the HeNB; and sending a message to the HeNB via a currently connected eNode B and a core network node to switch off the HeNB if the location of the UE is not within the range in relation to the location of the HeNB. - View Dependent Claims (7, 8)

9. A method for a core network node connectable to a Home eNode B (HeNB) and to at least one user equipment (UE) via a radio base station, wherein the at least one UE is authorized to access the HeNB, the method comprises the steps of:
-
receiving Femto Cell Location Information indicative of a location of the HeNB; forwarding the Femto Cell Location Information to the at least one UE via the radio base station wherein the at least one UE determines whether the UE is within a coverage of the HeNB based on a location of the at least one UE determined by the at least one UE; receiving information from the at least one UE that a HeNB should be switched off or switched on; and forwarding the information to the HeNB. - View Dependent Claims (10, 11)

12. A Home eNode B (HeNB) of a mobile telecommunication network, wherein the HeNB is connectable to a core network node of the mobile telecommunication network and is adapted to serve at least one femto cell and the HeNB is further connectable to a set of user equipment (UE) being authorized to connect to the HeNB, the HeNB comprises:
-
means for retrieving Femto Cell Location Information indicative of a location of the HeNB, a transmitter for sending the Femto Cell Location Information to the core network node for forwarding the Femto Cell Location Information to a UE authorized to connect to the HeNB, wherein the UE determines whether the UE is within or close to a coverage of the HeNB based on a location of the UE determined by the UE; means for receiving information from the core network node that the HeNB should either be switched off or switched on; and means for switching the HeNB off or on, according to the information received from the core network node. - View Dependent Claims (13, 14, 15, 16)
