Abstract
A method is provided for transmitting information related to the use of the Wireless Application Protocol between a first device and a second device coupled to a packet-switched data transmission network. A first protocol stack (201, 202, 203, 204, 205, 206, 207) is defined for the first device and a second protocol stack (251, 252, 253, 254, 255, 256; 511, 512, 513, 514, 515, 516) is defined for the second device. The protocol stacks consist of layers and serve the arranging of the mutual exchange of information between the first device and the second device. An octet stream protocol layer (206, 255) is defined for the transmission of unstructured octet streams as a certain layer in the first protocol stack and a certain layer in the second protocol stack. A Wireless Datagram Protocol layer (207, 256) is also defined as a certain layer above the octet stream protocol layer (206, 255) in the first and second protocol stacks. Information related to the use of the Wireless Application Protocol is exchanged between the Wireless Datagram Protocol layer (207) in the first device and the Wireless Datagram Protocol layer (256) in the second device through the use of the octet stream proto…
