- Abstract
- Presence service is available in most of recent IP-based communication systems, and depending on the characteristics of the systems, more presence information is provided. However, in the systems that a real-time property is required, presence service should be provided limitedly and efficiently because it is in the trade-off relation with a real-time property. This paper intends to propose a method of efficiently collecting and providing information on members’ mobile communication conditions in industrial group communication systems where a real-time property is emphasized.
