A technique for performing signaling conversion between an HTTP stateful session and an SIP dialog is described. In a method realization of this technique, an HTTP request message including HTTP state information is received from an HTTP enabled entity. In response to receipt of the HTTP request message, an SIP message belonging to an SIP dialog is created. In further steps, the first SIP message is sent to an SIP enabled entity, and a mapping between the HTTP state information and the SIP dialog is established.

The technique comprises determining a resource capability information indicating a capability of the media resource; transforming the resource capability information into service capability information indicating a capability related to a service accessible at the network-registered device via the network; and providing the service capability information to an access-requesting entity ().

Technique for providing access to a media resource attached to a network-registered device

An arrangement and method in a communication system such as an Orthogonal Frequency Division Multiplexing (OFDM) radio receiver for reducing the impact of interference from an intermittent interfering signal transmitted by an interfering system which may be co-located with the OFDM system or may be remotely located. Each OFDM symbol in a received OFDM signal includes a guard interval (GI), a middle portion, and a last portion identical to the GI. The arrangement determines which portion of each OFDM symbol is contemporaneous with the interfering signal and time-shifts a fast Fourier transform (FFT) window in the OFDM receiver to minimize or eliminate FFT processing of samples of the OFDM symbol that are contemporaneous with the interfering signal, thereby minimizing the impact of the interfering signal.
