  • Patent number: 9756090
    Abstract: The invention relates to techniques for providing services in a service provisioning network (100?), wherein a service-related message (118) is routed by a service routing node (104?) to a service hosting node (106?). A method embodiment of the invention comprises in the service routing node the steps of receiving, e.g. from the service hosting node, service availability information (124) indicating an availability of the service in the service hosting node; and establishing, based on the received service availability information, a service routing rule.

  • Patent number: 9544375
    Abstract: 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.

  • Patent number: 9531817
    Abstract: 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.

  • Patent number: 9491244
    Abstract: 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.

  • Patent number: 9185173
    Abstract: 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).

  • Patent number: 9077742
    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.

  • Patent number: 8972935
    Abstract: 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.

  • Patent number: 8838687
    Abstract: The invention refers to a method of correlating a plurality of service instances by a service composition entity, wherein the services are performed by one or a plurality of servers of a telecommunications network. Thereto, the service composition entity performs the steps of invoking a composite service instance corresponding to the service request, and generating a composite service identifier identifying this composite service instance, contacting the one or a plurality of application servers for invoking the plurality of component service instances, wherein the plurality of component service instances are associated to the composite service instance, and sending a first service report comprising an information about the composite service instance to a service supervision system, wherein this information enables the service supervision system to identify reports about the component service instances as being associated to the composite service instance.

  • Patent number: 8625602
    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.
