ABSTRACT:
A simple and efficient means of checking the registration authorization is proposed by the method and the device for checking the registration authorization prior to the start of the re-registration process based on a registration query from a mobile radio terminal to at least one access device for an intra-domain handover in a mobile communication network. In the network, a token which has been sent by an access device to a mobile radio terminal and has been stored in at least one trust table of at least one access device, is received by at least one further access device during a registration query from a mobile radio terminal and compared with tokens stored in at least one trust table prior to the start of the registration for the purpose of verifying the registration authorization, and the registration is started if an authorization is present.
