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.

Claims

1. A computer-readable medium storing a container for signaling an aggregate of data items, the medium comprising:

a container payload comprising at least one data item;

a container header comprising;

at least one transport object identifier entry describing a container identification; and

at least one transport object identifier entry describing a container version;

at least one transport object identifier entry containing the container identification; and

at least one transport object identifier entry containing the container version.

2. The computer-readable medium of claim 1, wherein the at least one transport object identifier entry describing a container identification comprises a length of the container identification entry.

3. The computer-readable medium of claim 1, wherein the at least one transport object identifier entry describing a container version comprises a length of the container version entry.

4. The computer-readable medium of claim 1, further including a field within the header that identifies whether the container is static or dynamic.

5. A mobile terminal for receiving data of an electronic service guide, the mobile terminal comprising:

a display; and

a processor programmed with computer-executable instructions for performing the method comprising;

(a) extracting a description of a container identification from a transport object identifier;

(b) extracting a description of a container version from the transport object identifier; and

(c) extracting from the transport object identifier a container identification based on data obtained in (a).

6. The mobile terminal of claim 5, wherein the processor is further programmed with computer-executable instructions to perform the method comprising:

(d) extracting from the transport object identifier a container version based on data obtained in (b).

7. A method of providing an update to an ESG, comprising:

(a) providing a container, the container comprising;

(i) a transport object header,

(ii) at least one ESG fragment descriptor; and

(iii) at least one ESG fragment for use in updating the ESG;

(b) providing at least one transport object identifier entry associated with the container;

the transport object identifier entry including;

(i) a container version; and

(ii) a container identification.

8. The method of claim 7, wherein the container is provided with an ALC/LCT transport object.

9. The method of claim 8, wherein the ALC/LCT transport object includes a LCT header and the transport object identifier entry is provided in the LCT header.

10. The method of claim 7, wherein the ESG fragment descriptor is provided in the transport object header.

11. The method of claim 7, wherein the transport object identifier entry is provided in the transport object header.

12. The method of claim 7, further comprising:

(c) encoding at least a portion of the container with a compression algorithm.

13. The method of claim 12, wherein the container is provided with a LCT header and the LCT header includes sufficient information regarding the container identification and the container version for determining whether the container should be decoded.
