Abstract: A method executed by an Intermediary Node arranged between a Client and a Server for participating in the setting up of a connection between the Client and a Server is described. In response to intercepting a first message, the method transmits from the Client and destined for the Server, and requests for a connection to be set-up between the Client and the Server. The method recognizes, based on content of the received first message, that it is desirable for the Intermediary Node to perform at least one function on the requested connection, the Intermediary Node is transmitting a second message to the Client, comprising an identity of the Intermediary Node. This enables the Client to accept or reject the Intermediary Node as a node participating in the requested connection set-up.

Abstract: A method is provided, in a server, operatively connectable to a client via a data connection, a method of sending a data stream to the client. The method comprises receiving from the client, a request for data, the request comprising a communication identifier, obtaining a first part of the data stream from a streaming source for sending to the client and sending, to the client, a streaming data message. The streaming data message comprises: the first part, the communication identifier, and a stream indicator, indicating a second data message may follow, comprising a second part of the data stream. The method does not comprise resending the streaming data message if no acknowledgement of receipt has been received from the client. Also a method in a client is provided, as well as the server and the client.

Abstract: A validation method for validating IP information header in data packets from user equipment connected to a mobile telecommunications network (1) and accessing an IP network (5) through a proxy. In the method trusted location information of the user equipment (2) from a trusted source of the telecommunications network is requested (109). Then, the trusted location information is inserted into the IP information header of a message (112) to be sent to a location based function (17).

Abstract: A system and method for correlating communication sessions. A globally unique correlation identifier is created and exchanged between the parties during Session Initiation Protocol (SIP) session setup to allow for association and correlation of additional SIP sessions between the same parties or with additional parties. The correlation information may then be used by network and session entities to perform different services.

Abstract: A control device (104) for controlling communication in an Internet Protocol Multimedia Subsystem IMS (150) coupling a user equipment (160, 162, 164) and an application provider (170, 172, 174) providing an application, the control device (104) comprising a receiving unit (190) adapted for receiving location information indicative of a location of the user equipment (160, 162, 164), a verification unit (192) adapted for verifying if the received location information matches a spatial area and a spatial condition in relation to the spatial area, wherein the spatial area and the spatial condition are part of a control criterion being associated with the application of the application provider (170, 172, 174), and a control unit (194) adapted for controlling a provisioning of the application to the user equipment (160, 162, 164) according to a result of the verification unit (192).

Abstract: 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.
