Push-to-Talk (PTT) is a half-duplex and one-to-many voice group communication. In past decades, PTT service has been widely adopted in various areas, including practical military, police, security, rescue, and emergency radio communication, etc. In addition, PTT service has also annunciated being an IP Multimedia Subsystem (IMS)-based service defined by Open Mobile Alliance (OMA), which is called Push-to-Talk over Cellular (PoC).Context-aware computing derived from the field of ubiquitous computing as a technique for imbuing application services with an awareness of users’ surroundings and situations for achieving transparent interaction. Thus, a user can obtain some reasonable and proper services among context-aware interactions. In this paper we try combine the features of PoC and context-aware service to implement a context-aware PoC service based on the Open IMS core. The context-aware PoC service can be aware to filter context information and to form an applicable PoC session according to the current contexts of participant PoC users. By the way, our implemented context-aware PoC service can be realizedly used to play an applicable IMS application service in the next generation network (NGN).
