  • Patent number: 10291557
    Abstract: An application server (204, 300), a first user equipment, UE, (200, 400), a second UE (206, 500) and corresponding methods for use in an Internet protocol multimedia subsystem, IMS, and for streaming media content between the first UE and the second UE using the Rich Communications Services, RCS, standard. The first UE transmits media content to an application server (204, 300) as an RCS file transfer. The application server receives the media content from the first UE as an RCS file transfer and stores the media content in a memory (306). The first UE compiles a message comprising a media content identifier and transmits the compiled message to the second UE using an RCS text based communication. The second UE receives the RCS text based communication from the first UE and transmits a request for the media content to the application server.

  • Patent number: 10123085
    Abstract: A method of synchronizing streaming media between a plurality of UEs connected to a communications network, wherein the UEs are involved in a SIP-enabled voice session over said communications network. A timestamp is provided to each of the UEs. Each of the UEs then sends a request for streamed media to an IPTV service, receives streamed media from the IPTV service, and commences playout of the streamed media in dependence upon the timestamp.

  • Publication number: 20120221722
    Abstract: A method can be executed at a notifier of a communication system for the purpose of handling notifications, at least partly according to a notification scheme. The basis of the method is to provisioning for a differentiated distribution rate to be applied together with the notification scheme when distributing notifications which have been received from a notification source function and which are associated with the subscriber. The provisioning is based on user traffic statistics on traffic involving a registered subscriber, and which has been generated in the communication network, and where the statistics has been acquired from a statistics server and accumulated by the notifier.

  • Patent number: 8165308
    Abstract: A wireless electronic arrangement configured to connect to an earphone arrangement may include a signal generator to generate an electric signal to be sent over the earphone arrangement; a measuring arrangement to make at least one measurement of the electric signal to determine a value indicating a current acoustic impedance of the earphone arrangement; a control unit to compare the determined value with a stored value indicating an operational acoustic impedance stored on a memory unit and, based on a result of the comparison, to select an operational mode of the wireless electronic arrangement based on the determined state of the earphone arrangement.
