Abstract

The invention is based on a distributed service architecture. The invention utilizes one or more agents for offering and supplying a service to a user. An agent includes service data and functions for executing a service. Furthermore, when necessary the agent is capable of moving in a packet-based telephone network to a part of the network where it can best execute the service desired by the user. An individual network element must incorporate one or more execution platforms providing the agent with the facility to execute services, communicate with other agents, and utilize the resources of the network element.

Claims

1. A packet-based telephone network in which telephony services are offered to a user, said network including at least one telephone server comprising call control means, characterized in that for offering telephony services, the network comprises:

user-related agents including user-specific telephone service data and functions for executing services, and being capable of moving, when necessary, in the telephone network to an individual network element,

at least one execution platform in an individual network element, providing the user-related agent with the facility to execute services, communicate with other agents, and utilize the network resources.

2. A network as claimed in claim 1, wherein a home telephone server has been defined for an individual user of the network, characterized in that the user'"'"'s home telephone server comprises an agent including all user-specific services and service data.

3. A network as claimed in claim 1, characterized in that the network further comprises a mobile agent including user-specific telephony services and service data.

4. A network as claimed in claim 1, characterized in that the user'"'"'s home telephone server comprises an agent including all user-specific services and an agent moving in the network, including user-specific telephony services and service data.

5. A network as claimed in claim 4, characterized in that the interface between the agent on the user'"'"'s home telephone server and the agent moving in the network is an application-related interface between the agents.

6. A network as claimed in claim 4, characterized in that the interface between the agent on the user'"'"'s home telephone server and the agent moving in the network is a prior art standard interface.

7. A method for implementing telephony services in a packet-based telephone network, characterized in that one or more agents including user-specific telephone service data and functions for executing the services execute the service desired by the user in such a way that when necessary, the agent can relocate in the telephone network to an individual network element to execute the service, and when necessary utilize the resources of the network element to execute the service, said network element comprising one or more execution platforms providing the agent with the facility to execute services, communicate with other agents, and utilize the network resources.

8. A method as claimed in claim 7, characterized in that the agent including all user-specific services of the user is permanently tied to an individual network element, wherein when the user roams in the operational area covering said element the user has all user-specific services at his disposal.

9. A method as claimed in claim 7, characterized in that the agent moving in the network includes user-specific telephone service data that it can execute at any network element.

10. A method as claimed in claim 8 and claim 9, characterized in that the agent moving in the network and the agent including all user-specific services of the user, which is permanently tied to an individual network element, co-operate in executing the service desired by the user.

11. A method as claimed in any one of claims 7-10, characterized in that the user-specific service is changed by reconfiguring the user agent, without any need to make changes in the resources of the user'"'"'s home subscriber server.

12. A method as claimed in any one of claims 7, 9, 10 or 11, characterized in that the agent moving in the network utilizes the user location data available to the network upon moving in the network.

13. A method as claimed in claim 12, characterized in that the agent moving in the network relocates to the network element in the operational area of whose telephone server the user is located.
