receive a response including the list from the external server using the service enabler;

determine, using the service enabler, that the received list includes first information corresponding to the second application that corresponds to one or more functions that the first application is operable to control to perform;

provide the first information corresponding to the second application or second information obtained based on the first information to the first application in case that the first information is determined to be included in the received list using the service enabler; and

transmit data generated by the first application to the host server based on the information provided to the first application between the first information and the second information.

12. The portable communication device of claim 1 , wherein the instructions further cause the processor to be operable to control to:
