Abstract

A method of transmitting data in a communications system 110 with protocol layers comprising communications protocol layers 112, 114 and an application layer 120 corresponding to a data transfer protocol e.g. HTTP or WAP to which the data is subjected; the data being transmitted with a level of error protection that is varied as a function of the category of the data e.g. text, video, sound, according to a priority specification provided by a user 130. In one embodiment the data is transmitted between a client 150 and a server 160. The priority specification can be static, for example in the form of a configuration table, or can be varied dynamically. The level of error protection can be further varied dependent on the category of the data responsive to communication link (115) conditions of said communications system. Also described are an apparatus for transmitting data in a communications system; an apparatus for allocating a varying level of error protection to data to be transmitted in a communications system; and an apparatus for providing a priority specification for determining varying levels of error protection to be allocated to the transmission data in a communications system.
