Claim:
1. In a mobile communication system, a method comprising: receiving, by a network, mobile terminal capacity associated with a robust header compression (ROHC) scheme; configuring, by the network, at least uplink parameter and at least one downlink parameter relating to the ROHC scheme based on the mobile terminal capacity; and transmitting, by the network, the configured at least one uplink parameter and the at least one downlink parameter, wherein the at least one uplink parameter comprises an uplink Max_CID informing of a maximum number of contexts, which is used for a compressor in a mobile terminal and the at least one downlink parameter comprises a downlink Max_CID informing of a maximum number of contexts for a decompressor in the mobile terminal, wherein the at least one downlink parameter and the at least one uplink parameter comprise a first profile parameter and a second profile parameter different from the first profile parameter, and wherein the first profile parameter and the second profile parameter are used for the decompressor in the mobile terminal and the compressor in the mobile terminal with respect to the types of packets supported by the decompressor in the mobile terminal and the compressor in the mobile terminal.
