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.
Claims24
A control method, in a home network of a terminal roamed in a visited network connected to said home network, of controlling service function chaining of said home network, the method comprising
- 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.
A utilizing method, in a visited network roaming a terminal of a home network connected to said visited network, of utilizing for said terminal a service function of service function chaining of said home network, the method comprising
- receiving, from said home network, information related to said service function chaining, and
- transmitting, to said home network, information related to an intended utilization of said service function for 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.
A control system, in a home network of a terminal roamed in a visited network connected to said home network, for controlling service function chaining of said home network, the control system comprising
- a control function entity configured to controlling said service function chaining,
- a recognizing device connected to said control function entity and configured to recognize, that said terminal is roaming in said visited network, and
- a detecting device connected to said control function entity and configured to detect, that said visited network supports utilizing service functions of said service chaining, wherein
- said control function entity comprises a applying device configured to apply 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.
A utilizing system, in a visited network roaming a terminal of a home network connected to said visited network, for utilizing for said terminal a service function of service function chaining of said home network, the utilizing system comprising
- a receiving device configured to receive, from said home network, information related to said service function chaining, and
- a transmitting device connected to said receiving device and configured to transmit, to said home network, information related to an intended utilization of said service function for 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.
