Abstract: In one embodiment, a system for context-based management of cached content includes policy and context servers. The policy server makes policy decisions controlling, e.g., usage of a content cache by a user, based on a contextualized policy that includes one or more context-dependent policy rules. The context server collects context information for the user and generates the contextualized policy by inserting the updated context-parameter(s) into the context-dependent policy rule(s). The policy server thus obtains or otherwise updates the contextualized policy responsive to a policy decision request received from a caching agent operating as a policy enforcement point, and returns a policy decision to the caching agent. In support, the context server may be configured to collect context information for the user at least in part by receiving context information from a user agent associated with the user.

Abstract: A distribution method and apparatus for distributing multimedia files from service providers (20) to subscribers (30) is described herein.

The promotion server (26) may promote the identified multimedia files to subscribers (30A) of the first service provider(20A) using a weight-based approach.

Abstract: Implantable and/or wearable medical data acquisition devices (30) associated with an individual, each having NFC communication capability, collect medical data. Each device has a unique identifier. The medical data are read from the devices via a secure link by an NFC reader or transceiver (26) in a wireless communication system mobile station (10) having a unique identifier. The medical data are selectively transmitted via a secure link from the mobile station to a Presence and Group Management (PGM) server (32, 34) configured to manage data services for medical groups. Secure access to the medical data by medical professionals is restricted according to a policy system (36). Encryption keys are managed on a group basis by a group key management server (32), assigning the medical data acquisition devices (30) and mobile station (10) to groups based on their unique identifiers. The PGM server (32, 34) may send alerts and/or information to the user via the mobile station (10).

Abstract: Method and apparatus for checking an aggregated web service requested by a terminal user (200). A web service authentication node (208) receives and stores a published description of the aggregated web service, as offered from a primary web service provider (204) and involving one or more sub-services offered from one or more secondary web service providers (206a,b). When the authentication node (208) receives a request made by the user for the aggregated web service, it is checked whether the sub-services and secondary service providers of the aggregated web service are acceptable for the user according to a policy of the user. If all sub-services and secondary service providers are deemed acceptable or safe, the aggregated web service can be authenticated. Otherwise, the request is rejected or the user is warned that the aggregated web service is deemed unsafe. Thereby, access to sensitive user data by secondary service providers can be controlled and made visible.

Abstract: The invention comprises methods and arrangements for Policy Decision Point discovery in a roaming or handover scenario in an IP network (IN) comprising a plurality of network elements. The authentication function, e.g. an AAA-server, receives the address (ASPDP1) of the serving Policy Decision Point (SPDP1) associated to the user equipment, and stores the address of the serving policy decision point together with the local address of the user equipment. The authentication function sends the address of the serving policy Decision Point to the Home Agent so that the Home Agent can forward the address of the serving policy decision point to the anchor Policy Decision Point and so that the anchor Policy Decision Point can contact the serving policy decision point by using said address of the serving Policy Decision Point.

Abstract: A device retrieves a first subset of events from data associated with a network, and determines one or more discriminating features of the first subset of events using a feature selection method. The device also retrieves one or more additional subsets of events, different than the first subset of events, from the data associated with the network, and cross validates the one or more discriminating features based on the one or more additional subsets of events. The device further detects a feature that is a root cause of a problem in the network based on the cross validated one or more discriminating features.

Abstract: A method and apparatus for offering a service to at least one client in a communication network for a specific client context, by means of a service provisioning unit. A history of client activities involving service usage in associated client contexts, is recorded in an activity database. Service templates are composed for associated client contexts based on the recorded history of client activities. When a context detector detects that the specific client context prevails, a service configurator selects a service template for the detected client context and configures a customised service from the selected service template. The customised service can then be offered to the at least one client.

Abstract: The invention comprises methods and arrangements for Policy Decision Point discovery in a roaming or handover scenario in an IP network (IN) comprising a plurality of network elements. The invention comprises methods and arrangement in an user equipment for receiving the address of the serving policy decision point and sending to the Home Agent a registration request comprising the local IP address of the user equipment so that the home agent can register the local IP address. The registration request will also comprise the address (ASPDP1) of the serving policy decision point (SPDP1) so that the Home Agent can forward the address of the serving policy decision point to the anchor Policy Decision Point and so that the anchor Policy Decision Point can contact the serving policy decision point by using said address of the serving Policy Decision Point.

Abstract: A method and apparatus for monitoring the behaviour of an individual communication client (200) in relation to the behaviour of a group of communication clients. A client database (202a) collects client data based on activities reflecting the individual client's behaviour, where the collected client data forms a resulting client behaviour profile (GP). A comparing unit (202b) compares the collected client data with a behaviour profile (GP) of the client group reflecting the behaviour of the client group. An alert generator (202c) then issues an alerting signal (A) if an unacceptable behavioural deviation between the individual client and the client group is detected.

Abstract: A method and apparatus for performing a caller investigation in order to provide relation information to a called party (200) regarding an unknown calling party (202), when implemented in a service entity (204) serving said called party. A relation query for the calling party is received from the called party, and it is then determined whether the calling party is known and related to any third party directly or indirectly known to the called party by checking a contact list (210-214) defined for said third party. The reliability of the calling party can then be better assessed based on how the calling party is related to the called party, if related at all. The called party may use this information for deciding how to respond to a communication request from said calling party.

Abstract: A method and apparatus for enabling user services in a communication network with a plurality of terminal users. An initiating user terminal (200) executes a group discovery process with the terminals (202) to form a user group. Capabilities are exchanged with the terminals, including at least one of: functional resources, available services, equipment information, applications or data programs, and current traffic or connection characteristics When a group service request (R) is received from a user terminal (D) in the group, functions and actions required for the requested service are assigned to functional resources in the terminals based on the exchanged terminal capabilities. The requested group service can then be consumed by means of these functional resources without involving an operator controlled group management server.

Abstract: A method and apparatus for obtaining context information from a context server maintaining a context for an object of interest in a telecommunication network. The context server receives raw context data from sensors associated with the object of interest. A request is received from a requesting party for refined context information with reference to the object of interest. Individual context data is collected for at least one individual entity of the requesting party. A customized rule is created on the basis of the received individual context data. The rule defines conditions in an adapted request for refined context information regarding the object of interest, which is sent, including the customized rule, to the context server of the object of interest. Context data refined according to the customized rule is then received from the context server.
