摘要： A method and system for generating an allowed list based on regions for a wireless terminal are disclosed. The method generates an allowed list based on regions to control network access of a stationary wireless terminal, and includes: sending, by the wireless terminal, an attach request to a network; creating, by the network, an allowed list that contains information on regions in which the wireless terminal is permitted to access the network; and controlling, by the network, network access of the wireless terminal on the basis of the allowed list. Hence, the allowed list, which stores information regarding regions in which the MTC terminal 110 is permitted to access the network, may be dynamically created by the terminal or the MME.

摘要： A wireless communication system for performing a handover to a femto base station is provided. The system includes user equipment, a femto subscriber information storage, a core network entity or a macro base station or a serving base station. The femto subscriber information storage stores a list of femto base stations that allows the access of user equipment, i.e., an accessible list. The core network entity or the macro base station receives and stores the accessible list. When any of the user equipment requests a handover toward a femto base station as a target base station, and the target base station is included in the accessible list stored, the core network entity or the macro base station requests a handover toward the target base station. A method for performing a handover to the core network entity and the macro base station is also provided.

摘要： A regional access control method is provided in a Mobility Management Entity (MME) for network access for a User Equipment (UE) that performs Machine-to-Machine (M2M) communication. An access request message and location information of the UE are received from a base station. The access request message is transmitted to the MME in response to reception of the access request message at the base station from the UE. A location of the UE that is determined based on the location information of the UE, is registered in a Home Subscriber Server (HSS). An allowed list of the UE is obtained from the HSS. It is determined whether the location information of the UE is registered in the allowed list.
