Maximum matching means that the MSC searches all lists of call prefixes for the best match with a called number, and then the MSC determines such call attributes as service category, service attributes, route selection, and called number type based on the matched call prefix. Assume that a subscriber dials 13901234567. Among the prefixes 13, 139, 13901, and 1390123, the MSC determines that the best match is 1390123 according to the maximum matching method.
