Abstract: The invention pertains in general to the testing of the operation of radio and other data transmission apparatus. In particular the invention pertains to the testing of the operation of a digital radio apparatus on the basis of error statistics. In order to test functions relating to data transmission, a simulation system produces a pseudorandom bit sequence or some other test sequence which is packed into downlink frames and sent to the data transmission apparatus tested. In accordance with the invention, a known number of errors are generated in the test sequence. As the data transmission apparatus tested compares the received test sequence to the sequence it has produced, it detects the errors in the received sequence and compiles various error statistics, e.g., in the form of bit error ratio (BER) or frame erasure ratio (FER).

Abstract: Message exchange handling concept. A message exchange session between wireless communication terminals via a wireless network is initiated from one of the terminals. The user of the initiating terminal invites at least one other communication terminal to participate in the message exchange session. This is done by forwarding a message text to said at least one other communication terminal. Then the other terminal responds to received message by inputing a message text for replying to the received message. Then the responding terminal automatically adds the inputted reply message text to the received message text, whereby the aggregate message text includes the message exchange session history, and the aggregate message text is then transmitted to the other communication terminals being party to the message exchange session.
