Abstract
A method of controlling an attach procedure of a device 1 to a telecommunications network 140 following receipt of an attach rejection from the telecommunications network, the method including assessing the authenticity of the attach rejection, and selecting a criterion for performing a subsequent attach attempt by the device to the network in dependence upon the authenticity assessment. The authenticity may be assessed by determining whether the rejection was received by an authenticated communication link or a signed message. The authenticity may also be assessed by checking that the cause of the reject is consistent with information held by the device. The selected criterion may be power cycling of the device or the passage of a time period.
