Abstract
Content discovery and content transfer between mobile communications nodes is often required, for example, to synchronize maps, traffic hot spot information and the like for vehicle mounted satellite navigation devices, pedestrian hand-held personal digital assistants and other mobile communications nodes. In an embodiment, content discovery processes using a tree-based data structure for transferring data between two mobile communication nodes is described.
Claims20
A method comprising:
- at a communications network node of a communications network having a memory storing a plurality of files that it synchronizes with at least one other communications network node in the communications network comprising:
- storing the plurality of files in a plurality of groups;
- using a processor at the communications network node to generate, for each group, a group hash;
- using the processor at the communications network node to create and store a tree-based data structure using the respective group hashes;
- creating an advert including information about the plurality of groups and the tree-based data structure;
- and
- broadcasting the advert on the communications network.

A method comprising:
- at a first communications network node of a communications network having a memory storing a plurality of files that it synchronizes with a second communications network node in the communications network comprising:
- storing the plurality of files in multiple different groups;
- generating, using a processor at the first communications network node, for each group, a group hash;
- generating, using the processor, a unique root hash corresponding to the plurality of files;
- creating and storing, using the processor, a tree-based data structure using the respective group hashes, the tree-based data structure including the unique root hash;
- creating an advert including the unique root hash;
- and
- broadcasting the advert on the communications network.
