Composite services provision with code download on demand

摘要

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).

主权项

1. A method for executing a composition of at least first and second service instances by a network device of a telecommunication network, the method comprising:
receiving a description of a selected service from a service composition node; initiating selecting a composition of at least the first and second service instances, wherein the composition is based on the description of the selected service; downloading, from a code storage node, at least one of:
a first code of the first service instance; anda second code of the second service instance; executing the composition of the first service instance and of the second service instance by processing both the first code and the second code.
