Method and system for preserving content timing across femtocell interfaces via timestamp insertion
Aspects of a method and system for preserving content timing across femtocell interfaces via timestamp insertion are provided. In this regard, a femtocell may receive a first time-stamped packet via a first interface and transcode the time-stamped packet. The femtocell may buffer the transcoded packet based on a time-stamp recovered from the packet and may transmit the buffered transcoded packet via a second interface. One of the first interface and the second interface may utilize the Internet Protocol. One of the first interface and the second interface may be a non-cellular interface and the other interface may be a cellular interface. The femtocell may be operable to generate a timestamp corresponding to a time instant at which a time-stamped packet arrived via the first interface or the second interface. The timestamp may be referenced to a clock within a cellular enabled communication devices communicatively coupled to the femtocell.
1. A method for communication, the method comprising:
receiving in a femtocell, a first time-stamped packet via a first interface of said femtocell;
transcoding said time-stamped packet;
buffering said transcoded packet based on a timestamp recovered from said time-stamped packet; and
transmitting said buffered transcoded packet via a second interface of said femtocell.
2. The method according to claim 1 , wherein one of said first interface and said second interface utilizes an Internet Protocol.
3. The method according to claim 1 , wherein said first interface is a non-cellular interface and said second interface is a cellular interface.
4. The method according to claim 3 , comprising generating, in said femtocell, a timestamp corresponding to a time instant at which said time-stamped packet arrived via said non-cellular interface.
5. The method according to claim 4 , comprising inserting said timestamp into said transcoded packet.
6. The method according to claim 4 , wherein said timestamp is referenced to a clock of one or more cellular enabled communication devices communicatively coupled to said cellular interface.
7. The method according to claim 1 , wherein said first interface is a cellular interface and said second interface is a non-cellular interface.
8. The method according to claim 7 , comprising generating, in said femtocell, a timestamp corresponding to a time instant at which said packet arrived via said cellular interface.
9. The method according to claim 8 , comprising inserting said timestamp into said transcoded packet.
10. The method according to claim 8 , wherein said timestamp is based on a network time of a network communicatively coupled to said non-cellular interface.
11. A system for communication, the method comprising:
at least one processor for use in a femtocell, said at least one processor is operable to receive a first time-stamped packet via a first interface of said femtocell;
said at least one processor is operable to transcode said time-stamped packet;
said at least one processor is operable to buffer said transcoded packet based on a timestamp recovered from said time-stamped packet; and
said at least one processor is operable to transmit said buffered transcoded packet via a second interface of said femtocell.
12. The system according to claim 11 , wherein one of said first interface and said second interface utilizes an Internet Protocol.
13. The system according to claim 11 , wherein said first interface is a non-cellular interface and said second interface is a cellular interface.
14. The system according to claim 13 , wherein said at least one processor is operable to generate a timestamp corresponding to a time instant at which said time-stamped packet arrived via said non-cellular interface.
15. The system according to claim 14 , wherein said at least one processor is operable to insert said timestamp into said transcoded packet.
16. The system according to claim 14 , wherein said timestamp is referenced to a clock of one or more cellular enabled communication devices communicatively coupled to said cellular interface.
17. The system according to claim 11 , wherein said first interface is a cellular interface and said second interface is a non-cellular interface.
18. The system according to claim 17 , wherein said at least one processor is operable to generate, in said femtocell, a timestamp corresponding to a time instant at which said packet arrived via said cellular interface.
19. The system according to claim 18 , wherein said at least one processor is operable to insert said timestamp into said transcoded packet.
20. The system according to claim 18 , wherein said timestamp is based on a network time of a network communicatively coupled to said non-cellular interface.
