Abstract
An Internet Protocol traffic filter is provided for a mobile radio network. A database stores access privileges of the mobile station for accessing a remote host, and access privileges of the remote host for accessing the mobile station. A processor receives data from the mobile station addressed to a remote host. The processor accesses the database to determine whether the mobile station is allowed to access the remote host, and denies access if access is unauthorized. Otherwise, the processor sends the data to the remote host if access is authorized. The processor also receives data from a remote host, and determines whether the remote host is allowed to access the mobile station. The processor denies access to the mobile station if the remote host is unauthorized. Otherwise, the processor connects the remote host to the mobile station if access is authorized.
