  • Patent number: 8996019
    Abstract: The invention relates to a method in a communication node (10,200,201,202,211,212,222) for commonly managing resources in a radio access network between different network access technologies, which communication node (10,200,201,202,211,212,222) is comprised in a radio access network of a radio communications network. The communication node receives (71) from a first local resource manager (111) of a first network access technology, a first report of information regarding resources needed per service associated with the first network access technology, which service is associated with a first local service priority. The communication node (10,200,201,202,211,212,222) then receives (72) from a second local resource manager (112) of a second network access technology, a second report of information regarding resources needed per service associated with the second network access technology. The service is associated with a second local service priority.

  • Patent number: 8638753
    Abstract: The technology pertains to wireless telecommunications systems in which a quality of service is handled for a service provided to a user equipment when the user equipment transitions from being served by a source network to being served by a target network. The quality of service is handled even if the source and the target networks implement proprietary QCIs. In general, a source QCI, which may be proprietary to the source network, is remapped to a predetermined QCI that identifies a set of predetermined QCI characteristics whose values are similar to the source QCI characteristics identified by the source QCI. The predetermined QCI and the set of predetermined QCI characteristics are used by the target network to provide the service to the user equipment after the transition.

  • Patent number: 8311542
    Abstract: The invention relates to a method in a second communication node within a communications network supporting a handover process of a first communication device from a first cell in the communications network to a second cell of the second communication node in the communications network. The second communication node determines (12) that a handover is to be performed of the first communication device from the first cell to the second cell. The second communication node then estimates (T4) an offered bit rate for the communication device within the second cell of the second communication node based on at least one parameter of the second cell. The offered bit rate is then transmitted (T6) in a message to the first communication device from the second communication node.

  • Patent number: 8191100
    Abstract: A method and terminal for providing Internet Protocol Television (IPTV) and other communication services to a group of users, such as a family, using an IP Multimedia Subsystem (IMS) network. A group private user identity is associated with a group public user identity and with a plurality of individual public user identities, each of which is associated with a different user in the group. Utilizing the group private User ID and the group public User ID, a browser registers a group subscription with the IMS network. When an individual user enters an identifier such as a PIN, the individual is then registered with the IMS network, while maintaining the group registration with the IMS network and the IPTV network. Individual users can be changed without having to restart the browser.

  • Publication number: 20120030707
    Abstract: The present invention relates to methods and arrangements for providing an improved channel change solution for and IPTV system. This is achieved by sending an additional FCC (Fast Channel Change) media stream using multicast from a fast channel change server. The FCC media stream contains a stream being a copy of the main stream wherein the speed is higher than the speed of the main stream. The FCC media stream may start with an I or S-frame and a number of STBs can use the same FCC multicast stream.

  • Publication number: 20110222406
    Abstract: The invention relates to a first communication device arranged to provide congestion indications to a second communication device. The first communication device comprises a control unit arranged to determine to apply an indicating congestion mechanism on a first radio bearer to the second communication device based on a quality of service setting of the first radio bearer. The control unit is further arranged to set a congestion threshold value and a first drop threshold value of a packet buffer associated to the first determined radio bearer. The congestion threshold value indicates that when buffered packets in the packet buffer exceeds the set congestion threshold value the control unit is arranged further to transmit over a transmitting arrangement at least one congestion indication to the second communication device.
