Abstract: A method for providing an output data stream in a network system comprises receiving a request for a desired output data stream and identifying at least one input data stream on the basis of the desired output data stream. The method further comprises identifying at least one relationship between the at least one identified input data stream and the desired output data stream, determining at least one operator on the basis of the at least one identified relationship and creating a query for generating an output data stream corresponding to the desired output data stream. The query is created by applying the at least one operator to the at least one identified input data stream.

Abstract: The present invention is aimed to carry out an effective handover between a first and a second serving call control servers in order to fit suitable server capabilities for servicing a user, as well as to provide a mechanism whereby a subscriber server may upgrade the selection criteria for assigning the second serving call control server. Therefore, the present invention provides a new method and enhanced servers for re-assigning the second serving call control server, whereby the still ongoing sessions for the user in the first serving call control server are kept alive, and where a serving call control server is arranged to report towards the subscriber server what portions of a user profile are not understood or not supported at said serving call control server.

Abstract: Currently existing mechanisms to optimize the quality of experience (QoE) in accordance with user data plans are rather based on user self-managed usage of his mobile user data plan with, for example, help from external applications which continuously evaluate the limits reached. There is thus a need for deployment of intelligence in the network, in order to avoid abrupt downgrades in the QoE for subscribers that go over the monthly quota of their data plan. To overcome these problems, or at least to mitigate them, an embodiment of the present invention provides for an optimization of the user's quota by gradually reducing the required bandwidth for the content that the user requests. This is achieved by a method which takes into account the consumed/remaining volumes in the user data plan as well as the user browsing habits, and which provides context enrichment to content providers to enable taking decisions.

Abstract: It is presented a method for notifying at least a first condition in an industrial system by means of a monitoring system in order to draw the attention of an operator monitoring the industrial system to the at least one condition. The method comprises displaying (S1) the first condition in a first portion of a display screen of the monitoring system, determining (S2) by means of eye tracking an area where a user focuses on the display screen, the area where the user focuses differing from the first portion, and alerting (S3) the user of the first condition in order to allow the user to be notified of the first condition in the industrial system. A monitoring system is also presented herein.

Abstract: A continuous query result estimator for use in a data stream management system. The data stream management system configured to execute a continuous query against data items received via at least one input data stream to generate at least one output data stream. The continuous query result estimator comprises a classification module configured to classify a set of at least one data item received via the at least one input data stream into one of a plurality of input data groups. A data store configured to store a respective rule for estimating a result of executing the continuous query against a data item belonging to the input data group. The continuous query result estimator also includes a result estimation module configured to select a rule from the rules stored in the data store on the basis of the classification performed by the classification module.

Abstract: A method of operating a Call Session Control Function node within an IP Multimedia Subsystem network. The method comprises establishing a first session corresponding to a first IP Multimedia Subsystem communication service using a first Application Server, receiving a request for a further session corresponding to a further IP Multimedia Subsystem communication service, and forwarding said request to a further Application Server. Said further Application Server is additionally notified that said first communication service is ongoing and of the nature of said first session.

Abstract: A data scheme and protocol (DSP) adapter which translates communications received from one or more application servers (FEs) into corresponding communications understandable by one or more repositories (BEs). The DSP adapter comprises an interface unit which receives a FE query from a FE. The DSP adapter comprises a processing unit which determines an FE query pattern fulfilled by the FE query and checks whether the FE query pattern exists for the FE query in an accessible memory. Where the FE query pattern does not exist in the accessible memory, the processing unit transforms the FE query pattern into a corresponding BE query pattern. Where the FE query pattern exists in the accessible memory, the processing unit obtains the corresponding BE query pattern from the accessible memory. A method for translating at a data scheme and protocol (DSP) adapter communications received from one or more application servers (FEs) into corresponding communications understandable by one or more repositories (BEs).
