Abstract
A method is provided for transmitting multimedia-related information between a terminal and a network device. A first protocol stack (201, 202, 203, 204, 205, 206, 207) is defined for the terminal and a second protocol stack (271, 272, 273, 274, 275) is defined for the network device. The protocol stacks consist of layers and serve the arranging of the mutual exchange of information between the terminal and the network device. A second network device intermediates the transmission of multimedia-related information. An octet stream protocol layer (206, 255) is defined for the transmission of unstructured octet streams as a certain layer in the terminal protocol stack and a certain layer in the second network device's protocol stack, and a network transmission protocol layer (264, 274) is defined for the transmission of data between the network devices. A multimedia messaging transport protocol layer (207, 275) is also defined as a certain layer above the octet stream protocol layer (206) in the terminal's protocol stack and the network transmission protocol layer (274) in the first network device. Multimedia-related information is exchanged between the multimedia messaging transport…
