Abstract:
A method for transmitting multimedia-related information between a terminal arrangement and a first network device arrangement, comprising the steps of:defining a first protocol stack for the terminal arrangement and a second protocol stack for the first network device arrangement, the protocol stacks consisting of layers, for arranging the mutual exchange of information between the terminal arrangement and the network device arrangement, defining a third protocol stack for a second network device arrangement, the protocol stack consisting of layers, for using the second network device arrangement as an intermediate device taking part in the mutual exchange of information between the terminal arrangement and the first network device arrangement, defining an octet stream protocol layer for the transmission of unstructured octet streams as a certain layer in the first protocol stack and a certain layer in the third protocol stack, defining a network transmission protocol layer for the transmission of data between the first network device arrangement and the second network device arrangement, defining a multimedia messaging transport protocol layer as a certain layer above said octet stream protocol layer in the first protocol stack and above said network transmission protocol layer in the second protocol stack and exchanging multimedia-related information between the multimedia messaging transport protocol layer in the terminal arrangement and the multimedia messaging transport protocol layer in the first network device arrangement through the use of the octet stream protocol layer as well as other lower layers in the first and third protocol stacks and through the use of said network transmission protocol layer as well as other lower layers in the second and third protocol stacks.
