The communication standards tend to be extremely technical and tedious documents defining the very behaviour of a given system. The IEEE 802 set of wireless communications standards for the Personal/Local/Metropolitan Area Network mainly specify the two lowest OSI layers (physical and link) of the system, yet they comprise of hundreds of pages requiring time and trained personnel to be comprehended. With the increasing pace of technology evolution the development and implementation of communication standards is calling for new approaches facilitating easier comprehension of standardised functionalities as well as development and testing of missing or unspecified procedures. In this paper we investigate the applicability of a Unified Modeling Language (UML) for modeling of communication standard, in particular the IEEE 802.16e network entry process. As an example we provide a high level overview of the process as well as more detailed view on the message passing sequences and subscriber station actions, and we conclude with some remarks on the suitability of the proposed approach.
