The invention enables using packet-switched network services, such as messenger services of Internet, through a subscriber connection belonging to some circuit-switched network. A subscriber can associate by phone a desired subscriber connection to a desired messenger service. This is termed "association". When association is initiated the desired subscriber connection can be reached from the Internet. Thus users of IP workstations can reach PSTN, ISDN and mobile subscriber connections through the messenger service by clicking the mouse. Also PSTN, ISDN and mobile subscribers may reach each other, and users of IP workstations through the messenger service. In this case, the subscribers must have an Internet connection. The invention is based on a new, messenger Access Control Point (MACP) named control point of PST network. The MACP has two basic tasks. First, it executes association, in other words, it enables a connection between a messenger service and a subscriber connection. Secondly, it routes a call, or data, to gateway when some person or service tries to connect the subscriber connection via a messenger service. Then the gateway route the call or data to the desired subscriber connection. The MACP operates as a logical bridge between the packed switched networks and the circuit-switched networks. |
