A network search is then made (1:5) in at least one search engine (106) using the refined search query. An aggregated search result from said network search is finally delivered (1:6) in response to the received search query.

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 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.

Abstract: A recommendation apparatus for determining, for a user, a set of one or more recommended routes going from a starting location to an ending location in response to receiving from the user a route request message identifying the starting and ending locations. Advantageously, in some embodiments, the route recommender apparatus determines a recommended route by analyzing a set of routes between the starting and ending locations, where each route in the set was traversed by a person who is in a “social graph” belonging to the user (e.g., each route in the set was traversed by one of the user's Facebook friends). In this way, routes can be recommended to the user based on routes that are popular with the user's friends.

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 method, apparatus and system for generating recommendations of items to users. Ratings of items made by users are collected (1:1). User behaviour information is also collected (1:2). Then correlations in ratings are obtained (1:3) and similarities in user behaviour amongst the users are obtained (1:4). Thereafter, an item for recommendation to a user is identified (1:5), based on both the correlations in ratings and on the similarities in user behaviour amongst the users and the item is recommended to the user (1:6).

Abstract: Application servers and methods of operating the same are provided for generating a personalized recommendation of items to a first user. An updated rating value N(t) of an initial rating value N(0) is determined for each rated item based on an age of each rating. The updated rating value N(t) is based on a difference between the value of the initial rating N(0) and a neutral rating value R, and on a predetermined half-life of the ratings. The updated rating value N(t) converges towards the neutral rating value R with an increase in the age t for each rating.

Abstract: Method and apparatuses for controlling a peer-to-peer communication involving media communication between a subscriber (A) and one or more opposite peers (B, C, D).

Abstract: A method is provided which enables ratings data registered by a number of users for a first service and at least one corresponding service to be collected, wherein each user have been federated for a Single-Sign-On (SSO) on the first service as well as on the corresponding service/s. In response to a request for a set of ratings data received from a user requesting for the first service, a group of users is identified and the SSO identity of each SSO federated user of the identified group of users is mapped to one or more service identities of the respective SSO federated user. The mapping enables ratings data associated with the SSO users of the identified group of SSO users to be collected and normalized, such that the requested ratings data can then be provided to the requesting user in a unified format.

Abstract: A method and an arrangement in a service assurance module for controlling service level agreements for communication services in a mobile services access network. A network performance rule is created for a service level agreement, and is based on an associated performance indicator indicating the current network performance with respect to the fulfillment of the service level agreement. The performance indicator is then monitored, and the network performance rule is evaluated on a regular basis based on the performance indicator. If the network performance rule is not satisfied, an agreement violation is registered and/or measures are taken to improve the network performance.

Abstract: Method and apparatus in a router (200) of an IP network, for providing a relevant and expected service level for a first subscriber (A) in a peer-to-peer session with a second subscriber (B). When a session setup message (PATH) sent from the first subscriber is received (2:2) at the router, a required service level is detected from a service level indicator in the received message, and a service level definition of an operator of the first subscriber is obtained (2:3) for interpreting the service level indicator. Communication resources required for data transmission during the session are determined (2:4) according to the detected service level as interpreted by the service level definition. The determined communication resources are then booked (2:4) in the router, and the session setup message is forwarded (2:7) to a next hop node in the transmission path towards the second subscriber.

Abstract: A method and an apparatus in a multimedia network node (312), for providing a relevant service level for a first subscriber (A) in a multimedia session with a second subscriber (B). A service level policy has been defined for each subscriber. A session negotiation message (3:1) sent by the first subscriber is first obtained. A required service level of the first subscriber is then detected from a service level parameter that the first subscriber has added to the negotiation message. The policy is updated (3:2a) for the second subscriber if the required service level cannot be allowed in the first subscriber's receive direction according to the original policy of the second subscriber, to allow that network resources are reserved (3:3) for the session such that the first subscriber will receive media (3:4) with the required service level.

Abstract: A method of estimating a default rating of a rated dataset is provided, where the dataset comprises at least one series of ratings associated with at least one user and each series comprise ratings associated with at least two items. For a reference user and an item for which a rated value is missing the item's average rating, ir, the reference users average rating, Ru, and the datasets average rating, dr, is collected. A Poisson distribution of the reference users rating is then generated on the basis of the reference users average rating. A random Poisson rating, ur, is calculated on the basis of the Poisson distribution, and a default rating, r, is estimated by weighting the random Poisson rating on the basis of the items average rating, the users average rating and the datasets average rating.

The technique further includes selecting, for at least one user terminal and from the plurality of services, a service not used by the at least one user terminal, wherein the service selection is based on the service utilization information provided for user terminals having a predefined association with the at least one user terminal as determined by the inter-terminal relationships, and sending a message indicative of the selected service to the at least one user terminal.

Abstract: A method is provided for determining a correlation between a reference user and another user on the basis of two sets of ratings, where each rating is associated with a respective user. In response to a trigger,user ratings associated with the reference user and user ratings associated with the other user are collected, and all co-rated items of these two sets are correlated in the basis of an adjusted cosine correlation function which is weighted by a first and a second weighting function. The correlation is then stored and may be repeated for a plurality of users. The stored correlations may be used e.g. for ranking purposes.

Abstract: A method and apparatus for automatically adapting a service level for a service consumed by a terminal user in a communication network, using a service level control system (308,312,400). A service usage analyser (308,402) collects information on service usage of the user, and estimates the user with respect to his/her service usage based on features of a usage pattern extracted from the collected service usage information. A subscription policy manager (312,412) then adapts the service level for service usage based on the user estimation, by adjusting or introducing a corresponding rule or policy in the user's subscription profile (304). The user will then consume the service with the new adapted service level.
