// 1.  If the reception is off, reject this message.
// 2.  If the user has set a time limit for receiving messages,
//     check if the current time is such that the message
//     should not be received.
// 3.  Check whether message's language has been subscribed.
//     Reject the message if not. If message id a Class 0 message,
//     do not reject, since the msg should be shown.
// 4.  If the topic detection is enabled and this message
//     is of an unknown topic, add the new topic and
//     reject this message (since the new topic cannot
//     be subscribed at this point).
// 5.  If the same message exists in the database, this
//     message is ignored.
// 6.  The decoder decodes the page.
// 7.  If the message is multipaged, it is given to 
//     the message collector.
// 8.  A complete message is forwarded to CCbsReceiverHelper,
//     which either stores the message into the database
//     or handles it as an index message.

//
// Note: Message reception status check may be unnecessary,
//       if the ETel Monitor instance handles the check.
//
// Note: Message subscription check is necessary here.
//       UI client's subscriptions might differ from MCN client's
//       subscriptions.
//
// Note: Language cannot be read from the header if the
//       language information is stored in the content of
//       the message. This is particulary troublesome, if 
//       the message is compressed.
