Abstract: An apparatus including at least one processing circuitry, and at least one memory for storing instructions to be executed by the processing circuitry, wherein the at least one memory and the instructions are configured to, with the at least one processing circuitry, cause the apparatus at least: to determine an abnormal operation of an external application with which at least one communication element has established a communication connection; to decide on a change of an uplink traffic to the external application; and to selectively control a communication of the at least one communication element to the external application by providing control information for the at least one communication element, the control information reflecting the decision to change the uplink traffic to the external application.

Abstract: Various communication systems may benefit from application control interworking in a network to expose certain service capabilities. For example, certain communication systems of the third generation partnership project (3GPP) that provide service capabilities that are exposed to application providers, for example, via open mobile alliance-application programming interface, may benefit from application control interworking in a network. Further, an application programming interface and the 3GPP system can act together to expose 3GPP service capabilities. A method may include receiving parameters of capabilities relating to an application server at a policy and charging rules function. The method may also include creating application detection and control rules based on the parameters received.

Abstract: There are provided measures for service function chain interworking. Such measures exemplarily comprise recognizing, that said terminal is roaming in said visited network, detecting, that said visited network supports utilizing service functions of said service chaining, and applying, at a control function entity controlling said service function chaining, a service function of said service function chaining to a service data flow of said terminal, said service function being determined based on information on said roaming of said terminal in said visited network.

Abstract: An apparatus including at least one processing circuitry, and at least one memory for storing instructions to be executed by the processing circuitry, wherein the at least one memory and the instructions are configured to, with the at least one processing circuitry, cause the apparatus at least: to acquire data indicating at least one available external service function or at least one external service function chain via a predetermined interface, to decide whether at least one of the indicated at least one external service function or at least one external service function chain is usable in a communication of a service data flow in the communication network, to select at least one from the indicated at least one external service function or at least one external service function chain for use on the basis of the decision whether at least one of the advertised at least one external service function or external service function chain is usable in a communication of a service data flow, and to provide, to an e

Abstract: An apparatus including at least one processing circuitry, and at least one memory for storing instructions to be executed by the processing circuitry, wherein the at least one memory and the instructions are configured to, with the at least one processing circuitry, cause the apparatus at least: to acquire generic service policy rules to be applied to a communication of a service data flow in a communication network, wherein the generic service policy rules are to be used for routing a service data flow to and within at least one external service function or at least one external service function chain; and to provide, to an external service function providing side, the acquired generic service policy rules as information related to an intended usage of at least one external service function or at least one external service function chain in a service data flow communicated in a communication network.

Abstract: It is provided a method, comprising monitoring if a second data path is established for a flow, wherein a first internet protocol address is configured for the flow via a first data path between an apparatus performing the method and a packet data network; assigning, if the second data path is established, a second internet protocol address different from the first internet protocol address for the flow via the second data path, wherein at least a part of the first data path belongs to a radio access technology; at least a part of the second data path belongs to the radio access technology; and the part of the first data path is different from the part of the second data path.
