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 |
20090117897 | METHOD AND APPARATUS FOR AUTOMATICALLY DETERMINING NEIGHBOR CELLS IN A WIRELESS TELECOMMUNICATION SYSTEM - Methods and apparatuses for automatically determining neighbor cells are disclosed. Cell information is received. The received cell information is compared with a list of old neighbor cells. When a new cell is detected, a determination is made as to whether the detected new cell covers the same geographical area as any of the old neighbor cells. When the new cell covers the same geographical area as at least one of the cells of the list, the new cell is stored as a neighbor cell in the list. Cell information is received. The received cell information is compared with a list of old neighbor cells. New neighbors are detected based on the comparison. A determination is made as to whether there are cells in a same geographic area as the new neighbors. A determination is made as to whether there are new cells in a same geographic area as the old neighbor cells. The new neighbors, the cells in the same geographic area as the new neighbors, and the new cells are stored as neighbors in the list. | 05-07-2009 |
20100165867 | Method and Arrangement in a Telecommunication System to Indicate Characteristics of an Access Node to a Mobile Terminal - The present invention relates to a solution for indicating cell characteristics that apply specifically for a mobile terminal ( | 07-01-2010 |
20100195592 | Header Compression in Wireless Links - In compression of packet data headers the compressor side ( | 08-05-2010 |
20100195622 | Method of Maintaining Broadcast Service Continuity - An access node in the boundary area of a single frequency network service area transmits a boundary indication to the mobile terminals in the boundary area to notify the mobile terminals that they are approaching the boundaries of the single frequency network. The mobile terminals receiving the boundary indications may then take steps to maintain continuity of broadcast services when the mobile terminals leave the service area of the single frequency network. | 08-05-2010 |
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 |
20100323662 | Communicating Cell Restriction Status Information between Radio Access Network Nodes - A cellular radio communications network includes a core network coupled to a radio access network (RAN) that has multiple RAN nodes for communication with mobile radio terminals. Each of the multiple RAN nodes serves one or more cells. At least one cell associated with a first RAN node is in a restricted or reserved access state in which access to the one cell is restricted for at least some mobile radio terminals. The first RAN node sends a message to a second RAN node to inform the second RAN node of that restricted access cell. The fact that the restricted status of the one cell has changed is detected. A global message tha is not related to a specific mobile terminal is generated that includes information that the restricted status of the one cell has changed. The first RAN node sends the global message to the second RAN node to inform the second RAN node of the change in the restricted status of the one cell. | 12-23-2010 |

20110179168 | Systems and Methods for Managing Temporary Users of a Wireless Communication Network - In some embodiments, the present invention relates to systems and methods for providing temporary access to a wireless communication network to user equipment (UE). More particularly, the present invention relates to systems and methods of handling a UE's access to a wireless communication network upon expiry of permission to access the network. | 07-21-2011 |
20110274051 | DISTRIBUTION OF ACCESS CONTROL INFORMATION IN A NETWORK - Methods and systems described herein may provide for the updating, maintenance, and/or transference of a CSG White List that is stored on a user equipment. The CSG White List may be implemented to store information related to the access of CSG cells, such as, for example, femto cells. Additionally, methods and systems described herein may provide for the updating, maintenance, and/or transference of an access control database. The access control database may be stored in one or multiple devices in a communication system. The access control database may be implemented to store information regarding home nodes and which user equipment is allowed to access the femto cell or CSG cell provided by each home node. | 11-10-2011 |
20120122422 | Access Network Discovery and Selection Function, ANDSF, Node Distributing Closed Subscriber Group, CSG, Information - The invention relates to a method in an Access Network Discovery and Selection Function, ANDSF, node for distributing Closed Subscriber Group information. The CSG information comprises an Allowed CSG List of a first UE and cell information indicating position of a cell with controlled access associated to the Allowed CSG List. The method comprises retrieving an Allowed CSG List of the radio cell from a CSG Database over a first network | 05-17-2012 |
20130272149 | METHOD AND SYSTEM FOR CONFLICT DETECTION IN SELF ORGANIZATION NETWORK (SON) FUNCTIONS - A system and method for detecting cooperation or conflict between actors in a network made up of self-organizing sub-networks examines parameters such as performance indicators and configuration parameters to determine whether or not different actors are adjusting configuration parameters in a way that is cooperative or conflicting. When a performance indicator is observed to be outside of its expected range, an acceptable convergence range can be defined to give the actors time to adjust and return the performance indicator to its expected range of values. When a performance indicator is detected to be non-convergent, the monitor can alert an operator, or another node, so that appropriate actions can be taken. | 10-17-2013 |
