User access method, access server and wireless network node

The invention provides a user access method, an access server and a wireless network node. The method includes the following steps: an access request message is sent to the access server, wherein the access request message includes an identification (ID) of a target user so that access server is enabled to obtain an account opening attribute of a target user corresponding to the ID of the target user in a stored corresponding relation of the ID of the user and the account opening attribute; the account opening attribute of the target user, returned by the access server, is received; and when the account opening attribute of the target user is an HRPD (high rate packet data) user, the session type of the target user is determined to be an HRPD session. The user access method, the access server and the wireless network node are capable of improving the accuracy of user access.
