Abstract: The present invention provides a relocation of content sources that provide media content to a mobile terminal (mobile node) when a network layer-level handoff occurs. The relocation of content sources enables the mobile terminal to seamlessly execute an application that utilizes the media content from a current content source before the handoff and from a new content source after the handoff. The mobile terminal registers with a current access router in order to inform the access router about application context information. The current access router informs a new access router about the impending handoff. The new access router consequently discovers the new content source.

Abstract: A master clock in a first radio network unit, configured for sending data packets at predetermined time intervals, is synchronized with a slave clock in a second radio network unit. To provide a method for packet based clock recovery being able to achieve the desired accuracy within an acceptable time while avoiding a high computational complexity, the following procedure is used. An estimate value is determined for the transmission delay time for each data packet in a predetermined set of data packets. At least one pair of data packets is selected that has a minimum estimate value for the transmission delay time. A difference of the reception times of the selected pair of data packets is determined. Finally, a clock estimate procedure is performed using the difference of the reception times of the selected pair of data packets to determine the quantity representative of the clock frequency difference and/or the clock time offset.

Abstract: A data processing system processes data arrays that collectively describe cyclic behavior of at least one variable in several entities in a physical process. Each cycle comprises several time slots. An input routine (2-4) receives multiple data arrays, each data array containing multiple data items, each of which describes a variable of an entity in one time slot. A magnitude-determination routine (2-6) determines a specific magnitude parameter, such as average, volume or peak, for each of the several entities. A scaling routine (2-8) scales the data arrays between entities such that the specific magnitude parameters are suppressed and only their shape is maintained. A training routine (2-10) trains a clustering system with a first plurality of the scaled data arrays, to determine a set of cluster centers. After training, a clustering routine (2-12) applies a second plurality of the scaled data arrays to the trained clustering system.
