Patent number: 8244247Abstract: 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.Type: GrantFiled: May 8, 2008Date of Patent: August 14, 2012Assignee: Nokia CorporationInventors: Vijay Devarapalli, Meghana Sahasrabudhe, Basavaraj Patil, Kengatharan Sivalingam, Franck Le

Patent number: 7953799Abstract: 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.Type: GrantFiled: February 23, 2001Date of Patent: May 31, 2011Assignee: Nokia Siemens Networks OyInventors: Basavaraj Patil, Khiem Le, Stefano Faccin, Curt Wong, Srinivas Sreemanthula, Kengatharan Sivalingam

Publication number: 20020120746Abstract: The present invention relates to a method and system for providing a service in a communication network. A service script is used to control a service execution functional unit to execute the service, wherein an execution priority is allocated to the service script based on the kind of service. Furthermore, a service logic of the service may be provided at a service execution functional unit, and the service script may comprise a service description of the service. The service execution functional unit is then controlled based on the service description to execute the service by using the service logic. Thus, the service script does not contain the service logic, and a flexible service script concept can be provided. Moreover, the signaling traffic can be reduced since the operator does not have to update service scripts for a large amount of subscribers.Type: ApplicationFiled: February 23, 2001Publication date: August 29, 2002Inventors: Basavaraj Patil, Khiem Le, Stefano Faccin, Curt Wong, Srinivas Sreemanthula, Jari Mutikainen, Kengatharan Sivalingam
