    Patent number: 8570924
    Abstract: The present invention relates to a method and arrangement for efficient use of network resources, in particular for continuous connectivity services. The present invention introduces a set of established rules for uplink and/or downlink activity detection such that a Node B and/or a UE is enabled to detect active and inactive transmission periods on links for reception of packet data transmission and can independently arrange for inactivity/activity state transitions without any need of further signalling. Such a set of rules can be communicated to the Node B and the user equipment, e.g., from the radio network controller (RNC), or can consist of a predefined set of fixed rules that is readily implemented in said units.

  • Resource management
    Patent number: 8572620
    Abstract: The invention relates to a method, device and system for management of resource in a communication network having a resource owner (RO) providing the resource and at least one resource user (RU) using the resource. According to the present invention a resource broker is introduced between the resource owner and the at least one resource user. Said broker is arranged to perform a management procedure for deciding whether to perform a allocation, keeping or release of resource. In order to take a decision a resource usage measure (TTL) is used. In accordance with the present invention said measure is updated when user's usage measure (Keep Alive, InterestMsg) informing about the expected usage of the resource by a resource user is obtained. The update is performed by means of a cumulative algorithm taking into account current and past values of the resource usage measure (TTL).

  • Combined storage and transmission of scalable media
    Patent number: 8571215
    Abstract: The invention involves collective management of video and audio content in a content provider. The video and audio content is available in multiple potential versions, e.g. in the form of scalable media or media pre-encoded to fixed bandwidth levels. The video and audio data is associated with bandwidth share information enabling estimation of a respective apportionment of a total available bandwidth to the video and audio content. The provider uses this share information and information of the total assignable bandwidth level for providing a respective video version and audio version from the multiple potential versions. This allows for increased user-quality when rendering the video and audio data as optimal video and audio version can be dynamically provided during the media session.

The second node (310) selects a serving gateway (308) in the visited network (300v). Based on the parameter, the second node (310) selects a visited PDN gateway (305v), in the visited network (300v) when the UE (301) is allowed to use the multimedia service in the visited network (300v). Based on the parameter, the second node (310) selects a home PDN gateway (305h) in the home network (300h) when the UE (301) is allowed to use the multimedia service in the home network (300h).
