Nokia Phone Manager Filtering As of release 188.8.131.52, Nokia PCS is made of several standalone programs. The Graphical User Interface ( GUI ), LaunchApplication.exe, allows the user to start the other operational sub-programs such as PCSync2. exe and ContactsEditor.exe, used respectively to synchronize data with a computer and to edit phonebook entries. These programs establish communication over a Remote Procedure Call ( RPC ) channel with the resident service of PCS, called ServiceLayer.exe. This service is started automatically by the operating system and is responsible for communicating with the phone. It makes use of the different protocols supported by Nokia phones ( i.e., AT, FBUS, and OBEX over FBUS ). PCS can be envisaged as two distinct parts: the application, which bundles the GUI and the operational sub-programs, and the service layer, which is a sub-layer of the application. Figure 5 illustrates the design. The upper-level applications run with the privileges of the user executing them. In contrast, the service layer runs with System privileges, which gives it total access to the operating system and the resources of the computer. It is also well protected against interference from a regular user's program, since the operating system prevents a process with regular privileges from accessing the address space of another process, unless they belong to the same user. That is, a regular process cannot read or write the memory allocated by or for a process having System privileges. Other restrictions also exist, including the interdiction for a lower-privilege process to create a thread or allocate memory in an upper-privilege process. The PCS service uses the Win32 API provided by the operating system. In this case, to communicate 1 with a Nokia 6101 ...Original publisher: Gaithersburg, MD: U.S. Dept. of Commerce, National Institute of Standards and Technology,  OCLC Number: (OCoLC)274228922 Subject: Cell phones -- Data processing.
