Abstract

A network node module includes a processing module and memory. The processing module is operable to generate a header section of a frame for transmission within a unified vehicle communication network. The header section includes a preamble, routing information, and a vehicle network field, which includes information that identifies a type of the frame. The processing module is further operable to generate a payload section of the frame. The payload section includes data payload and an integrity check field. The processing module is further operable to transmit the frame to the unified vehicle communication network in accordance with a global vehicle network communication protocol.

Claims

1. A method comprises:

generating a header section of a frame for transmission within a unified vehicle communication network, wherein the header section includes a preamble, a vehicle network field, and routing information, and wherein the vehicle network field includes information that identifies a content type of the frame;

generating a payload section of the frame, wherein the payload section includes data payload and an integrity check field; and

transmitting the frame to the unified vehicle communication network in accordance with a global vehicle network communication protocol.

2. The method of claim 1, wherein the header section further comprises at least one of:

a frame length field; and

a start of frame field.

3. The method of claim 1, wherein the routing information comprises at least one of:

a source address field; and

a destination address field.

4. The method of claim 3 further comprises:

the source address field including a source internet protocol (IP) address or a source physical device address; and

the destination address field including a destination IP address or a destination physical device address.

5. The method of claim 1, wherein the vehicle network field comprises one or more of:

the content type of the frame that includes one of a mission-critical data type, a network data type, a vehicle operation data type, and an information/entertainment data type; and

priority level of the frame.

6. The method of claim 1, wherein the vehicle network field further comprises:

one or more levels of sub-type information.

7. A network node module comprises:

a processing module;

memory operably coupled to the processing module, wherein the processing module operable to;

generate a header section of a frame for transmission within a unified vehicle communication network, wherein the header section includes a preamble, a vehicle network field, and routing information, and wherein the vehicle network field includes information that identifies a content type of the frame;

generate a payload section of the frame, wherein the payload section includes data payload and an integrity check field; and

transmit the frame to the unified vehicle communication network in accordance with a global vehicle network communication protocol.
