  • Evaluation means for a message-oriented layer-3 communication
    Patent number: 6034949
    Abstract: Program-controlled evaluation device for a message-oriented layer-3 communication between a communication switching installation and a peripheral installation of a communication device, using a first protocol, as well as for a message-oriented layer-3 communication between the communication switching installation and a terminal apparatus, using a second protocol via the peripheral installation. The first and the second protocol consist of function blocks (ADM, MAIN, TEST, REST, LINK, BCAST, LCE, MM, CC) identified through protocol discriminators. Each protocol message of the first and of the second protocol contains a protocol discriminator indicator. The evaluation device has a single main sequence control for function block-specific, table-controlled evaluation of the first and of the second protocol, using a protocol discriminator-dependent branching. As a peripheral installation, for example, a base station of a cellular communication device with wirelessly reachable terminal apparatus is provided.
