A regional access control method in a mobility management entity, MME, for network access for a User Equipment, UE, that performs machine to machine, M2M, communication, the method comprising the steps of: receiving (302; 602), from a base station, an access request message and location information of the UE in response to reception of the access request message transmitted from the UE; registering, by the MME, in a home subscriber server, HSS, a location of the UE that is determined based on the location information of the UE and transmitting (303; 603) a message to the HSS to request an allowed list of regions of the UE; obtaining, from the HSS, in response to the message, the allowed list of regions to which the UE is allowed access, information identifying a group to which the UE belongs, and information associated with a representative UE of the group; determining (305; 605) whether the location information of the UE is included in the allowed list; transmitting an access-allow message to the UE if the location information of the UE is included in the allowed list, and if the location information of the UE is not included in the allowed list, determining whether location information of the representative UE is identical to the location information of the UE, if the location information of the representative UE is identical to the location information of the UE, transmitting a message to the HSS to request an update of the allowed list of regions of the UE; obtaining, from the HSS, in response to the message, the updated allowed list; and transmitting an access-allow message to the UE based on the location information of the UE being included in the updated allowed list. receiving (302; 602), from a base station, an access request message and location information of the UE in response to reception of the access request message transmitted from the UE; registering, by the MME, in a home subscriber server, HSS, a location of the UE that is determined based on the location information of the UE and transmitting (303; 603) a message to the HSS to request an allowed list of regions of the UE; obtaining, from the HSS, in response to the message, the allowed list of regions to which the UE is allowed access, information identifying a group to which the UE belongs, and information associated with a representative UE of the group; determining (305; 605) whether the location information of the UE is included in the allowed list; transmitting an access-allow message to the UE if the location information of the UE is included in the allowed list, and if the location information of the UE is not included in the allowed list, determining whether location information of the representative UE is identical to the location information of the UE, if the location information of the representative UE is identical to the location information of the UE, transmitting a message to the HSS to request an update of the allowed list of regions of the UE; obtaining, from the HSS, in response to the message, the updated allowed list; and transmitting an access-allow message to the UE based on the location information of the UE being included in the updated allowed list.
