20090092097 | METHOD AND ARRANGEMENT IN A TELECOMMUNICATION SYSTEM - The described technology generally relates to method(s) and arrangement(s) for access control during relocation of a user equipment (UE) into a femto base station (FBS) and dynamic triggering of the relocation into the FBS. A white list is maintained in the UE. The white list includes information on a list of FBSs that the UE is allowed to relocate. The UE detects a target FBS and reports target FBS to a source macro base station (MBS). The source MBS makes a relocation request to a mobility controller. The mobility controller grants or denies the requests or allows the target FBS to make the decision. Upon grant, the UE is relocated to the target FBS. Otherwise, the white list is updated in the UE. | 04-09-2009 |

20100240397 | Handling location information for femto cells - 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. | 09-23-2010 |

20120157095 | CLOSED SUBSCRIBER GROUP (CSG) HANDLING FOR SUPPORTING NETWORK SHARING OF HOME BASE STATIONS - A system and method for enhanced support for handling of Closed Subscriber Groups (CSGs) and sharing of Radio Access Network (RAN) for home base stations and other small cells. An enhanced System Information (SI) structure indicates multiple CSG IDs and CSG Indications, thereby making it possible to support different CSG IDs and CSG Indications for every Public Land Mobile Network Identity (PLMN-ID) and also to support a PLMN-ID with multiple associated CSG IDs and CSG Indications. The enhanced SI makes it possible to have different CSG IDs for different operators, to have multiple CSG IDs for one operator (i.e., a single PLMN), and to selectively use the CSG concept for some PLMNs (as given by their respective CSG Indications), but not for all. A network of base stations (e.g., a RAN) thus can be effectively shared by multiple operators, leading to better cellular coverage, peak rates, and capacity. | 06-21-2012 |
