The invention concerns a method for method for optimising IP Header Compression of data packets stream exchanged between a first mobile terminal camping on a cell in a cellular communication network and a second terminal connected to Internet, said method comprising:
- encoding the IP header field,
- exchanging between said first mobile terminal an said second terminal a compression window comprising at least one reference value used by the first mobile terminal (respectively second terminal) for compression and to be used by the second terminal (respectively first terminal) for decompression, Said method comprising the following steps:
- When a handover procedure is started, adding at least one new reference value to the compression window for the subsequent decompression without removing the previous reference values from said window as long as the handover procedure is ongoing, and
- after the handover procedure is complete, removing all previous values at once from the compression window. |
