Method of restricting the use of a radio terminal and an associated restriction device |
摘要 |
A request to access the network sent by a terminal is intercepted and a selective restriction criterion is evaluated on the basis of parameters relating to the intercepted access request. A radio signal is sent to jam an acknowledgment signal sent by the network in response to the access request if the selective restriction criterion is satisfied.
