Abstract
A system and method of reducing control message signaling load in a radio telecommunications network. When an authentication request is issued by the mobile switching center (MSC), the home network performs authentication of the visiting subscriber. When authentication fails the home network determines if a threshold value is reached. If so, a suitable authentication code portion is included in the return message so that local authentication of the visiting subscriber may be performed. The MSC is able to locally authenticate a visiting subscriber trying to access the network thereby suppressing the transmission of additional authentication requests and failure reports to the home network. For failed authentications, the VLR transmits authentication failure reports to the home network. If a threshold value is reached the MSC locally authenticates the mobile subscriber's subsequent attempts so that the VLR is precluded from sending additional authentication failure reports to the home network.
