Service management system, and method, communications unit and integrated circuit for use in such system

摘要

When terminating an app (1), a communications unit (10) identifies any apps dependent on the app (1). In a case where an app (2) is dependent on the app (1), the communications unit (10) requests a communications unit (20) to terminate the app (2). In response to this, the communications unit (20) identifies any apps dependent on the app (2). In a case where an app (3) is dependent on the app (2), the communications unit (20) requests a communications unit (30) to terminate the app (3). In response to this, the communications unit (30) terminates the app (3), and notifies the communications unit (20) of the termination. In response to this, the communications unit (20) terminates the app ( 2 ) , and notifies the communications unit (10) of the termination. In response to this, the communications unit (10) terminates the app (1). As a result, the apps (1) to (3) are all terminated.
