A data compression control method allows sharing of a common data compression entity by a plurality of SNDCP entities belonging to different SNDCP layers operating with LLC unacknowledged mode traffic. In particular, utilizing V.42bis compression, sharing is achieved by re-initializing a common V.42bis compression entity from a currently assigned SNDCP entity with compression parameters associated with currently assigned SNDCP entity. Advantageously, the method includes resetting a shared V.42bis compression entity using the C-INIT primitive before an N-PDU is sent. Similarly, in data decompression, a common decompression entity is made available to a plurality of SNDCP entities operating with unacknowledged mode data traffic. Employing the invention in a node offering data compression/decompression reduces the amount of resources used for data compression/decompression.
