Furthermore, in an accounting process, accounting parameters are accumulated in an accounting information accumulating unit for variations on compressed source addresses, not on source addresses. As a result, the accounting information accumulating unit, etc. can be realized with normal circuit elements only. ## Claims ### Claim 1 A subscriber information processing system in a connectionless data service, comprising: a connectionless data processing station connected to a highway;
