Briefly, in accordance with one or more embodiments, an accounting management architecture for an operational support system for a wireless network comprises an accounting client capable of retrieving the accounting information from a base station and forwarding the accounting information to an accounting server of a connectivity service network (CSN) which may be the home CSN of the mobile station or a visited connectivity service network when the mobile station is roaming. If the mobile station is roaming, the visited CSN may function as a proxy/server between the visited accounting client and the home accounting server. An element management system may retrieve the accounting records and forward the accounting records to a billing processing system.
