    Abstract: A method for keeping the robust header compression communication continuous is provided. The method is that: during the progress of the robust header compression (ROHC) operating function entity handover, sending the ROHC channel parameters of the source ROHC operating function entity to the destination ROHC operating function entity; and after completing handover, if the ROHC channel parameters of the terminal and the network side haven't changed, the terminal and the destination ROHC operating function entity continue the ROHC operation by using the ROHC channel parameters; and if the ROHC channel parameters of the terminal and the network side have changed, the terminal and the network side renegotiate the ROHC channel parameters, and put into ROHC operation by using the renegotiated ROHC channel parameters. Meanwhile a communication system is also provided. By applying the invention, it can be achieved that keeping ROHC communication continuous during MS handover progress, such as ASN handover, R3 handover and exiting the idle mode.
