Abstract: A method (200) and a user terminal associated with a presentity (410) compress presence information in an XML format presence document, for wireless transmission in a wireless communication system. A dictionary-based compression is applied (220) to a first portion of the presence document, the first portion of the presence document comprising at least one item of uncompressible information. A non-dictionary-based, structured information representation method is applied (230) to a second portion of the presence document. The non-dictionary-based, structured information representation method may be ASN-1 encoding. The at least one item of uncompressible information may comprise a dynamic entity. The second portion of the presence document may comprise tags, enumerated strings, and/or XML fields. Each watcher (430) may receive and store an individual dictionary for each presentity (410) that it watches.
