Abstract
The invention provides an efficient transportation of ESG fragments to a mobile device through the formation of containers. In this sense, a container comprises at least one ESG fragment, but may contain a plurality of fragments. A fragment may be also carried in more than one container. Aspects of the present invention utilize a simple and extensible header structure apart from the fragments independent of the type and format of the individual fragments. In further embodiments, compression is applied over the entire container, including the fragments and any headers. In yet further embodiments, a 3GPP metadata envelope is carried within the container without the need for unnecessary repetition of parameters, such as for example, version, validity time, and identification. In further embodiments, a simplified container system allowing for the updating of previously received fragments is disclosed.
