Patent number: 9544375Abstract: 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.Type: GrantFiled: February 24, 2015Date of Patent: January 10, 2017Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Ioannis Fikouras, Roman Levenshteyn, Nikolaos Albertos Fikouras

Patent number: 9531817Abstract: The disclosure relates to a technique for providing interoperability between an Internet protocol multimedia subsystem (IMS) domain and a non-IMS domain. A method implementation of this technique comprises the steps of receiving on a service layer a service invocation message from a non-IMS domain, analyzing the message to identify the message as a request to invoke a service within the IMS domain, converting non-IMS session control protocol elements contained in the message into IMS session control related protocol elements, and generating an outgoing IMS message to establish an IMS control session.Type: GrantFiled: December 19, 2005Date of Patent: December 27, 2016Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Roman Levenshteyn, Ioannis Fikouras

Patent number: 9491244Abstract: A method is described for invoking a constituent service in a telecommunication network. The constituent service is associated to a composite service. A first group of parameters is determined which is associated with the composite service. A second group of parameters is determined which is associated with the constituent service. The first and the second group of parameters are compared. If there are matching parameters (212) in the first and the second group requirements are determined for the constituent service based on the matching parameters in the first and the second group. The constituent service (216) is invoked according to these requirements. An application server is also described.Type: GrantFiled: June 5, 2009Date of Patent: November 8, 2016Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Joerg Niemoeller, Eugen Freiter, Ioannis Fikouras, Roman Levenshteyn

Patent number: 9185173Abstract: It is described a concept for a service composition which can be carried out in a telecommunication network (100). The described service composition is optimized in view of a composite service execution in a mobile network device (110) having limited resources. According to the described concept, at least one code required for executing the composite service is downloaded from a code storage node (130) to a composition execution agent (112) in response to receiving a corresponding instruction from a service composition node (120), that the service should be composed and/or executed. The actual code to be executed within the network device (110) is selected in response to receiving a service composition command from the service composition node (120). The code selection may take into account local constraints available for the network device (110).Type: GrantFiled: December 22, 2009Date of Patent: November 10, 2015Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Raphaël Quinet, Eugen Freiter, Roman Levenshteyn, Joerg Niemoeller

Patent number: 8972935Abstract: An application server (102) along with various other devices and method are described herein for managing a service (e.g., communication service) which is provided to a user. As described herein, the application server with the help of aspect oriented programming is capable of automatically adding functionality to an original service without directly modifying the target application code of the original service. In particular, the application server when automatically adding functionality to a certain application can automatically detect which features are still missing within the certain application, and which are already supported.Type: GrantFiled: July 13, 2010Date of Patent: March 3, 2015Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Joerg Niemoeller, Roman Levenshteyn, Eugen Freiter, Raphael Quinet

Patent number: 8625602Abstract: 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.Type: GrantFiled: June 6, 2011Date of Patent: January 7, 2014Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Michael Jansson, Ioannis Fikouras, Salvatore Loreto, Elena Fersman, Goran Anders Petter Eriksson, Roman Levenshteyn, Gonzalo Camarillo
