IEEE 802.15.4 MAC User Guide PRELIMINARY
MAC function
calls
The services provided by the MAC are the capabilities it offers to the Application/Net-
work layers. This concept is illustrated in Figure 3-2, showing the relationship of the
Application/Network layer communicating through the corresponding MAC and lower
layers.
Figure 3-2. Layer Services
The MAC function calls are specified by describing the information flow between the
Application/Network layer and the MAC. This information flow is modeled by discrete,
instantaneous events, that characterize the provision of a function. Each event consists
of passing a function call between the layers. Function calls convey the required infor-
mation by providing a particular service. These function calls are an abstraction
because they specify only the provided service rather than the means by which it is pro-
vided. This definition is independent of any other interface implementation. Services are
specified by describing the function call and parameters that characterize it. A function
may have one or more related calls that constitute the activity that is related to that par-
ticular function. Each function call may have zero or more parameters that convey the
information required to provide the service.
A function call can be one of four generic types:
MAC functions are prefixed by wpan_ and callback functions are prefixed by usr_.
These prefixes are listed in Figure 3-1, further described in the following paragraphs,
and in Appendix A, B, C, and D. A detailed list of the function parameters (Data Dictio-
nary) is shown in Appendix E.
– Request: The request primitive is passed down from the Application/Network
– Indication: The indication primitive is passed up from the MAC. This event may
– Response: The response primitive is passed from the Application/Network
– Confirm: The confirm primitive is passed from the MAC to the
layer to request that a service is initiated by the MAC.
be logically related to a remote service request, or it may be caused by an
internal MAC event.
