Abstract
Abstract A method and apparatus for transmitting and/or receiving packets (e.g., CDMA packets, CDPD packets, etc.) cells (e.g., an ATM Channel). An illustrative method includes building a basic control octet for a packet of N bytes, the basic control octet including (1) an additional control bit that indicates if a supplemental control octet accompanies the basic control octet, and (2) a length indicator based on N.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
66 words
A method for generating the payload of a broadband cell based on a user packet comprising N octets, said method comprising: building a basic control octet which comprises: (1) an additional control bit that indicates if a supplemental control octet accompanies said basic control octet, and (2) a length indicator based on N ; packing said basic control octet and said user packet into said payload.
Claim 2
Dependent Claim
23 words
The method of claim 1 wherein said first basic control octet further comprises a parity bit based at least on said length indicator.
Claim 3
Dependent Claim
27 words
The method of claim 1 wherein said step of packing further comprises concatenating said first basic control octet and said first user packet in the recited order.
Claim 4
Dependent Claim
29 words
The method claim 3 wherein said step of packing further comprises aligning said first basic control octet and said first user packet with a boundary of said ATM payload.
Claim 5
Dependent Claim
26 words
The method of claim 4 further comprising the step of padding any unused portion of said ATM payload with copies of said first basic control octet.
Claim 6
Independent Claim
119 words
A method for generating an ATM cell payload based on a first user packet comprising M octets and a second user packet comprising N octets, said method comprising: building a first basic control octet which comprises: (1) an additional control bit that indicates if a supplemental control octet accompanies said first basic control octet, (2) a length indicator based on M ; building a second basic control octet which comprises: (1) an additional control bit that indicates if a supplemental control octet accompanies said first basic control octet, (2) a length indicator based on N; packing said first basic control octet, said first user packet, said second basic control octect and said second user control packet into said payload.
Claim 7
Dependent Claim
47 words
The method of claim 6 wherein: said first basic control octet further comprises a parity bit based on said additional control bit and said length indicator, and said second basic control octet further comprises a parity bit based on said additional control bit and said length indicator.
Claim 8
Independent Claim
114 words
A method for generating the payload of an Asynchronous Transfer Mode cell based on a user packet, which is associated with logical link Q and which comprises N octets, said method comprising: building a basic control octet that comprises: (1) an additional control bit that indicates that a supplemental control octet accompanies said basic control octet, and (2) a length indicator based on N ; building a supplemental control octet that comprises: (1) an additional control bit that indicates when an ancillary control octet accompanies said supplemental control octet, and (2) a logical link indicator based on Q; packing said basic control octet, said supplemental control octet and said user packet into said payload.
Claim 9
Dependent Claim
41 words
The method of claim 8 wherein: said first basic control octet further comprises a parity bit based at least on said length indicator; and said supplemental control octet further comprises a redundancy field based at least on said logical link indicator.
Claim 10
Dependent Claim
42 words
The method of claim 6 or 8 wherein said step of packing further comprises concatenating said first basic control octet, said first user packet, said second basic control octet and said second user control packet into said payload in the recited order.
Claim 11
Dependent Claim
39 words
The method claim 10 wherein said step of packing further comprises aligning said first basic control octet, said first user packet, said second basic control octet and said second user control packet with a boundary of said ATM payload.
Claim 12
Dependent Claim
32 words
The method of claim 11 further comprising the step of padding any unused portion of said ATM payload with copies of said first basic control octet and said second basic control octet.
