Abstract  Abstract

A telecommunication network having first and second entities (201 and 202) they are transmitted with compressed header (24 ) of the packet (22) to communicate; header compression key (23) associated with the packet (such as in it). header compression key has a first field (23A) in the first mode of the invention the field special compressed packet flow (CID) to distinguish different. the first field (23A) in the second mode of the invention the header compression key can be used to distinguish different compressed packet flow or for distinguishing different header compression identifiers. a first field header compression key is special compressing packet stream (first mode) to distinguish different or can also be used to distinguish different header compression identifiers (second mode) of the value in the second field (23B) depends on the header compression key. a first subset of values of the first field in the second mode the header compression key is used for distinguishing different header compression identifiers and a second subset of values of the first field is used for distinguishing different compression packet stream.

A telecommunications network has first and second entities (20 1 and 202) which communicate by sending a packet (22) having a compressed header (24). A header compression key (23) is associated with (e.g. included in) the packet. The header compression key has a first field (23A) which in a first mode of the invention is utilized exclusively for distinguishing between different flows of compressed packets (CIDs). In a second mode of the invention the first field (23A) of the header compression key can be utilized either for distinguishing between the different flows of compressed packets or for distinguishing between different header compression identifiers. Whether the first field of the header compression key is employed exclusively for distinguishing between different flows of compressed packets (the first mode) or can also be employed for distinguishing between different header compression identifiers (second mode) depends on a value in a second field (23B) of the header compression key. In the second mode a first subset of values for the first field of the header compression key is employed to distinguish between different header compression identifiers while a second subset of values for the first field is employed to distinguish between the different flows of compressed packets.
