20120079605 | Methods and Arrangements for Rendering Real-Time Media Services - The present invention relates to methods and arrangements for rendering a radio service. The radio service signal broadcasted to radio devices is divided into a plurality of different signals. The different signals may be retrieved via different channels and from different sources. Hence, the radio service signal is at least divided into a DJ signal containing a program guide and e.g. DRM keys, which may be retrieved from a media server e.g. hosted by a provider providing a radio channel and a payload signal, which may be retrieved from memory storage in device or a content server, with the payload (typically music). According to an embodiment of the present invention the radio signal comprises further a host signal. The host signal comprises voice content, commercial advertisements etc. The host signal may be retrieved from a content server e.g. hosted by the provider providing the radio channel. The radio service may be created by combining the DJ signal, the radio host signal and the payload signal, wherein the service is mastered by the DJ signal. | 03-29-2012 |
20130254414 | Service Access Apparatus, Method, Computer Program and Computer Program Product for Selective Initiation of Communication - It is presented a service access apparatus arranged to selectively initiate communication with a network node providing a service. The service access apparatus comprises: a data obtainer arranged to obtain a multilevel hierarchical identifier associated with a user of the service access apparatus and when the multilevel hierarchical identifier does not have a lower level first, reversing the multilevel hierarchical identifier; a concatenator arranged to determine a combined domain name; a domain name lookup client arranged to perform a domain name lookup using the combined domain name, and receiving a response of the domain name lookup; and a communication initiator arranged to, when the response comprises a valid resource record for the network node, initiate communication with the network node using a node pointer in the resource record. A corresponding method, computer program and computer program product are also presented. | 09-26-2013 |
20130316754 | DEVICES, METHODS, AND COMPUTER PROGRAMS FOR DETECTING POTENTIAL DISPLACEMENT OF A WIRELESS TRANSCEIVER - It is presented a method for detecting potential displacement of a wireless transceiver connected to a machine-to-machine device. The method comprises the steps, executed in a displacement detection server, of: receiving an updated radio environment message from the wireless transceiver, the radio environment message comprising updated radio characteristics of at least two radio cells, the updated characteristics being measured by the wireless transceiver; determining whether the updated radio characteristics differ significantly from previous radio characteristics of a previous radio environment message from the wireless transceiver; and when it is determined that radio characteristics differ significantly, sending a displacement indication message to a device management server, the displacement indication message indicating potential displacement of the wireless transceiver. Corresponding displacement detection server, host device, computer program and computer program product are also presented. | 11-28-2013 |
20130332627 | ENABLING IP-COMMUNICATION WITH A MACHINE TO MACHINE UNIT - A Proxy Unit is connectable to a communication network and is arranged to enable IP Communication with a Machine to Machine Unit. The Proxy Unit receives and stores in a session data base a first IP address a device identifier and a unique ID of the Machine to Machine Unit. The Proxy Unit then receives from a Machine to Machine application a message destined to the Machine to Machine Unit and comprising the unique ID of the Machine to Machine Unit. The Proxy Unit finds the associated device identifier and the first IP address in the session data base, using the received unique ID. If the Proxy Unit detects no active session for the Machine to Machine Unit, it uses the device identifier to send a wake up message to the Machine to Machine Unit for enabling IP communication. | 12-12-2013 |
