Abstract: The invention discloses a method of and apparatus for notifying account information of a data-type-oriented user equipment. The method comprises the steps of: determining whether each user satisfies a predetermined condition; and if the predetermined condition is satisfied, then causing a packet data network gateway to activate account information notification control information for the user, wherein the account information notification control information includes a network address of a web notification server. With the invention, the terminal user can get to know his own account information more timely to thereby adjust the usage mode of the wireless broadband data service according to the account information, for example, lower the frequency of accessing the service or disable the service for a duration to thereby avoid a large bill or perform prepayment charging to thereby prevent an important connection from breaking down due to an overdue account.
