Method of unified parameter mapping

1. A method of unified parameter mapping for a communication device comprising a medium access control (MAC) abstraction sub-layer for converging a plurality of media in a network system, the method comprising steps of:

obtaining a unified parameter and a value of the unified parameter from an upper layer of the MAC abstraction sub-layer, and a medium type of a MAC layer underlying the MAC abstraction sub-layer;

determining a special parameter for configuration of the medium type of the MAC layer and a format of the special parameter according to the medium type of the MAC layer and the unified parameter; and

generating a value of the special parameter according to the value of the unified parameter and the format of the special parameter.

2. The method of claim 1 , further comprising steps of:

determining a unified parameter index according to the unified parameter; and

determining a MAC type index according to the medium type of the MAC layer.

3. The method of claim 2 , wherein the step of determining the special parameter for configuration of the medium type of the MAC layer and the format of the special parameter according to the medium type of the MAC layer and the unified parameter comprises steps of:

determining a special parameter index corresponding to the special parameter according to the unified parameter index, MAC type index and a number of the media converged with the MAC abstraction sub-layer; and

determining the format of the special parameter according to the special parameter index.

4. The method of claim 3 , wherein the step of determining the special parameter index corresponding to the special parameter according to the unified parameter index, MAC type index and the number of the media converged with the MAC abstraction sub-layer comprises steps of:

obtaining the special parameter index by an equation:

Special parameter index=(unified parameter index-1)*MAC type number+MAC type index, wherein the MAC type number represents the number of the media.

5. The method of claim 3 , wherein the step of determining the format of the special parameter according to the special parameter index comprises steps of:

obtaining the format of the special parameter by a table predefined in the communication device and used for indicating the relation between special parameter indexes and corresponding formats.

6. The method of claim 1 , wherein the format of the special parameter includes a length and a type of the special parameter.

7. The method of claim 6 , wherein the step of generating the value of the special parameter according to the value of the unified parameter and the format of the special parameter comprises steps of:

transforming the value of the unified parameter to conform to the length and the type of the format of the special parameter; and

generating the value of the special parameter from the transformed value of the unified parameter.

8. The method of claim 1 , wherein the step of generating the value of the special parameter according to the value of the unified parameter and the format of the special parameter comprises steps of:

transforming the value of the unified parameter to conform to the format of the special parameter; and

generating the value of the special parameter from the transformed value of the unified parameter.
