Abstract: Document cluster ranking systems and methods of ranking document clusters are described. In some example embodiments, the method comprises: obtaining, at a document cluster ranking system, a value associated with a first feature for each of a plurality of document clusters; based on the values associated with the first feature, automatically generating, at the document cluster ranking system, a plurality of first feature bins, each first feature bin defining a range of values and a bin identifier; and obtaining a score for one of the document clusters, by: i) identifying the first feature bin having a range of values which includes the obtained value associated with the first feature for that one of the document clusters; and ii) determining a score for that document cluster based on the first feature bin identifier for the identified first feature bin.

Abstract: A method for re-using an existing IPSec tunnel for multiple services. The IPSec tunnel is established from customer premises equipment to the core network to support licensed frequency communications, such as a femtocell. UMA communication using unlicensed frequencies may be carried out by re-using the IPSec tunnel to securely route UMA communications from a UMA device to a UNC within the core network via the customer premises equipment. The network determines whether to redirect UMA communications through an existing IPSec tunnel by determining whether a newly established second IPSec tunnel for UMA communications originates from an access point collocated with a femtocell that has an existing IPSec tunnel.

Abstract: A multi-use embedded universal integrated circuit card contains more than one active MNO (mobile network operator) profile. The example card may include a time manager and a radio resource schedule for managing access to a radio within a wireless device. The time manager enables one of the active MNO profiles at a time in accordance with the radio resource schedule, effectively allocating respective time slices to applications associated with each of the active MNO profiles.
