20150118707 | METHOD AND DEVICE FOR DETECTING METABOLLICALLY ACTIVE CELLS - A method for the detection of metabolically active cells using microwells is provided. A sample containing one or more cells is segmented into a plurality of microwells each containing a metabolic indicator. The microwells are then monitored for a change in the level or activity of a metabolic indicator, thereby indicating the presence or absence of metabolically active cells in each microwell. Also provided are methods for the detection of cells such as bacteria that are resistant to antibiotics or for the detection of particular cell types such as mycobacteria. Also provided are screening methods for identifying compounds with an effect on cell growth or metabolism. | 04-30-2015 |

20130005328 | Handling Closed Subscriber Group Lists - A core network receives in an uplink message a first list of closed subscriber groups (CSGs) located within one gateway domain to which mobility is possible for a user equipment UE. The core network creates a third list by checking the first list received in the uplink message against a second list which is the UE's allowed CSG list, and sends the third list downlink to at least one of a serving gateway of the UE or a serving access node of the UE. In one embodiment the first list consists of all CSGs within a domain of the respective serving gateway/access node; and in another embodiment it consists of all neighbor closed subscriber group cells of the respective serving gateway/access node which sent the uplink message to the core network. In different embodiments the third list is a whitelist or a blacklist. | 01-03-2013 |
20140313982 | Method of Management in a Communications Network - A method including maintaining a database of unique radio network identifiers within a home node B gateway, wherein the unique radio network identifier uniquely identifies the radio network termination point of user equipment attached to a radio node controlled by the home node B gateway. | 10-23-2014 |
20150017925 | Allocation of Identifiers for Home Node BS - A technique including receiving neighbouring cell information specifying one or more cells as neighbouring cells for a first cell of a plurality of cells associated with a gateway entity; and selecting based on said neighbouring cell information an identifier for said first cell that distinguishes said first cell from any other cell of said plurality of cells associated with said gateway entity that specifies one or more neighbouring cells in common with said first cell. | 01-15-2015 |
