First Claim
Patent Images
1. A mobile radio terminal device (100), comprisinga communication means (110) for communicating with network elements via data packets;
- a control means which is implemented to perform an authentication with a first network element; and
a filter means (120) for monitoring the data packets, wherein the filter means (120) is implemented to receive a filter regulation from the first network element and to prevent a communication with a second network element, when a data packet for communicating with the second network element does not correspond to the filter regulation; and
wherein the control means is implemented to accept no filter regulations from the first network element in a failed authentication.

21. A method for monitoring data packets, comprising the following steps:
-
authenticating a first network element; receiving a filter regulation from the first network element, if the authentication succeeded; checking data packets, which are exchanged with a second network element, based on the filter regulation; and discarding data packets, which do not correspond to the filter regulation. - View Dependent Claims (22)

23. A network element (200) for the configuration of a filter means of a mobile radio terminal device, comprising
a communication means (210) for communicating with the mobile radio terminal device via data packets; - and
a filter configuration means (220) for providing a filter regulation such that the filter means may identify data packets which do not correspond to the filter regulation based on the filter regulation, wherein the communication means (210) is implemented to authenticate against the mobile radio terminal device and to transmit the filter regulation via the data packets to the mobile radio terminal device. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
