The invention discloses an access point and a terminal access method, which are used for solving the technical problem that under the household environment, a fixed network operator can not provide LTE (Long Term Evolution) wireless signals for LTE terminal users if the fixed network operator does not deploy network elements such as MME (Mobility Management Entity), SAE GW (System Architecture Evolution Gateway), HSS (Home Subscriber Server) and the like again. The AP (Access Point) provided by the invention comprises an eNodeB (Evolved NodeB) module, an MME module and an SAE GW module, a smplified wireless access system is realized based on the AP, and according to the system, the operator does not need to establish the network elements, such as MME/SAE GW/HHS and the like; and according to the access method provided based on the AP, the LTE service can be provided for the user, meanwhile, the AP can directly replace an existing wireless router of a WLAN (Wireless Local Area Network) under the household environment, and the IP (Internet Protocol) address of the operator is saved.
