This part of TIA-41 defines the distributed functional plane (DFP) for the Wireless Intelligent Network (WIN).

Specifically, the scope of this part of the Standard is:

1. To define the WIN functional entities and the relationships applicable to WIN.

2. To specify a high level model description of call control function (CCF) activities required to establish and maintain communication paths for users.

3. To specify a high level model description of service switching function (SSF) activities required for interaction between the CCF and a service control function (SCF).

4. To specify WIN triggers and provide a high level model description of detection point processing.

5. To describe mobility management and radio access control functions in the context of WIN.

6. To illustrate how the WIN basic call state models interact with TIA-41 signaling.
