A method for updating filters, at a Packet Data Serving Node, with a care-of-address associated with at least one of a mobile station or a correspondent node. The method includes the steps of implementing a soft filtering rule at a Packet Data Serving Node and receiving, by the Packet Data Serving Node, a care-of-address that is associated with at least one the mobile station and a correspondent node. The method also includes updating, by the Packet Data Serving Node, filters with the care-of-address to correctly identify flows belonging to a particular session during Mobile IP use. The method further includes filtering, by the Packet Data Serving Node, packets including a care-of-address that is associated with one of the mobile station and the correspondent node.

Service based bearer control and traffic flow template operation with mobile IP

The invention relates to a service control device and method for controlling service execution in a communication network. A service script for a user is loaded in response to the receipt of an incoming message, and it is checked based on a comparison of the loaded service script and the incoming message whether a service is to be triggered. If a service triggering has been determined, a service is activated in an external service execution environment. Due to the fact that the service execution is not performed in the service control point but in an external service execution environment, the service logic does not have to be provided at the service control point. It provides a flexible way to define, execute, and control user-specific, operator, and third party services combining various service capabilities.

Service control device and method

According to the present invention, a plurality of data packets are received and routed by a router () in a data network. The router () comprises storing means () for storing a pre-defined list of rules for detecting special data packets, detecting means () for detecting special data packets in the received plurality of data packets on the basis of the pre-defined list of rules stored in said storing means (), and routing means () for requesting instructions for the special data packets detected by said detecting means () and for routing the special data packets in accordance with instructions received on request. According to the present invention, an advanced service architecture for next generation network services is provided. In this service architecture, the functions of the detecting means () and the routing means () can be achieved by a service trigger and a service logic, respectively.

Advanced service architecture for next generation network services and intelligent data network router

A network system comprising a service control device (SEM); and at least one application execution device (AEE); wherein the service control device (SEM) is adapted to receive a service request, to select an appropriate application execution device according to the service request, and to invoke the selected application execution device, and wherein the application execution device (AEE) is adapted to perform the service requested by the service request. A corresponding network control method is also provided. According to the invention, a flexible service architecture is possible.

Internet protocol based service architecture

A communication system comprises an IP network offering services to users and an IPT provider network providing call related functions to users. A control protocol message is received and analyzed by a respective serving entity in the IPT provider network. Depending on the analyzing result, call related functions are performed by the respective serving entity. Moreover, a received control protocol message is analyzed by the IP network and, depending on the analyzing result, services are executed by the IP network.

IP based service architecture

This invention relates to communication arrangements between communication networks, specifically to arrangements allowing networks of different types to cooperate. The invention provides a method for providing packet data services for a mobile station homed in a second wireless communication network in a first wireless communication network, where the first and second wireless communication networks are based on different standards.

Method for roaming between networks

To diversify the calculation of advice of charge, a price definition element (AoC-I) is maintained in a telecommunications system. In order to use the correct price definition element (AoC-I), an indication of the price definition element (AoC-I) to be used in calculating the advice of charge of a service is associated with the service. The advice of charge of the service is calculated by the indicated price definition element (AoC-I).
