PROBLEM TO BE SOLVED: To provide a method for generating a coded profile that can use a coded profile adaptive to each call connection at transmission reception of packets. SOLUTION: A communication unit 10 transmits a profile including an identification code usable at a supply source to a communication unit 20 at connection before start of communication (at a time T1). The communication unit 20 receives the profile at a time T2, extracts common items among items included in an identification table on the basis of a common identification code to the supplied profile and a profile of the unit 20 in advance, the communication unit 20 extracting the common items stores a new coded profile and transmits the coded file to the communication unit 10 (at a time T3), the communication unit 10 receives and stores it (at a time T4) so that both the communication units share the coded profile in order to conduct negotiation.
