Abstract
Abstract A method and apparatus for enabling one or more packets (e.g., CDMA packets, CDPD packets etc.) to be encapsulated into a cell (e.g., an ATM cell, a B-ISDN cell) for transmission and/or reception over a broadband network (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: 13
Claim 1
Independent Claim
85 words
A method for generating a cell payload based on a user packet comprising N octets (where N is a positive integer), 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 cell payload; and padding any unused portion of said cell payload with copies of said basic control octet.
Claim 2
Independent Claim
85 words
A method for generating a cell payload based on a user packet comprising N octets (where N is a positive integer), 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 cell payload; and padding any unused portion of said cell payload with copies of said basic control octet.
Claim 3
Independent Claim
133 words
A method for generating a cell payload based on a first user packet comprising M octets (where M is a positive integer) and a second user packet comprising N octets (where N is a positive integer), said method comprising: building a first basic control octet which comprises: (1) an additional control bit that indicates if a first 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 second supplemental control octet accompanies said first basic control octet, (2) a length indicator based on N; and packing said first basic control octet, said first user packet, said second basic control octet and said second user control packet into said cell payload.
Claim 4
Independent Claim
133 words
A method for generating a cell payload based on a first user packet comprising M octets (where M is a positive integer) and a second user packet comprising N octets (where N is a positive integer), said method comprising: building a first basic control octet which comprises: (1) an additional control bit that indicates if a first 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 second supplemental control octet accompanies said first basic control octet, (2) a length indicator based on N; and packing said first basic control octet, said first user packet, said second basic control octet and said second user control packet into said cell payload.
Claim 5
Dependent Claim
49 words
The method of claim 2 wherein: said first basic control octet further comprises a parity bit based on said additional control bit and said length indicator M, and said second basic control octet further comprises a parity bit based on said additional control bit and said length indicator N.
Claim 6
Dependent Claim
33 words
The method of claim 2 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.
Claim 7
Dependent Claim
40 words
The method of claim 4 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 cell payload.
Claim 8
Dependent Claim
32 words
The method of claim 5 further comprising the step of padding any unused portion of said cell payload with copies of said first basic control octet and said second basic control octet.
Claim 9
Independent Claim
116 words
A method for generating a cell payload based on a user packet, which is associated with a logical link Q and which comprises N octets (where N is a positive integer), said method comprising: building a basic control octet that 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; building a supplemental control octet that comprises: (1) an additional control bit that indicates if 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 cell payload.
Claim 10
Independent Claim
116 words
A method for generating a cell payload based on a user packet, which is associated with a logical link Q and which comprises N octets (where N is a positive integer), said method comprising: building a basic control octet that 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; building a supplemental control octet that comprises: (1) an additional control bit that indicates if 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 cell payload.
Claim 11
Dependent Claim
40 words
The method of claim 7 wherein: said 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 12
Dependent Claim
46 words
The method of claim 7 wherein said step of packing further comprises: concatenating said basic control octet, said supplemental control octet and said user packet; and aligning said basic control octet, said supplemental control octet and said user packet with a boundary of said cell payload.
Claim 13
Dependent Claim
30 words
The method of claim 9 further comprising the step of padding any unused portion of said cell payload with copies of said basic control octet and said supplemental control octet.
