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.

Abstract: A method for coordinating the execution of a composed service in a service execution coordination unit on request by a service composition server is disclosed, wherein the service is composed of at least a first and a second component service instance. The method comprises: receiving an instruction for invoking the first component service instance from the service composition server, receiving an instruction for invoking the second component service instance from the service composition server, contacting a respective one of the one or more application servers for invoking the first component service instance, and in response to receiving a service invocation result from invoking the first service automatically contacting the respective one of the of the one or more application servers for invoking the second of the one or more component service instances.

Abstract: The present invention relates to a method for managing an execution of a composite service, the composite service comprising constituent services.

Abstract: It is described a concept for a service selection of at least two services of a composite service wherein a composite service description (100) of the composite service includes at least two service templates (102a, 102b, 102c), each of which defines at least one constraint for a service wherein the service is to be executed in place of the service template to thereby constitute part of the composite service. From service database there is selected for each service template a corresponding candidate set comprising at least one service matching the at least one constraint of the service template. Subsequently or at least partially simultaneously for each of the at least two service templates (102a, 102b, 102c), from the corresponding candidate set one service is selected so as to provide, based on a predetermined cost metric, for a reduced composition cost. The predetermined cost metric may include a latency metric, an energy efficiency metric, a co-location metric or a traffic metric, etc.

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).

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.

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.

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

Abstract: Methods and devices for controlling a charging of a composite service in a telecommunications network are described. The composite service comprises an invocation of a constituent service. The telecommunications network comprises a control node for controlling the composite service, a service node for providing the constituent service, and a charging system for performing the charging.

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.

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.

Abstract: The invention comprises a method and system for dynamically processing messages. After a message is received from a network or from an internal application, and the message type is identified, the invention determines whether an optimized handler should be used to process messages of the identified message type. If an optimized handler has not previously been generated for the identified message type or is otherwise not available, an optimized handler may be generated, during run-time, for subsequent processing of messages of the identified message type. In some embodiments, the invention maintains statistics relating the processing characteristics of different types of messages and these statistics are used to determine whether to generate an optimized handler or to use a generic handler to process subsequently received messages having a certain identified message type.
