Patent number: 8209213Abstract: The invention relates to a method for construction of a distributed workflow. A workflow specification comprising the invocation of a number of locatable functions is obtained. The workflow specification is divided into partitions based on the host nodes where the locatable functions are hosted. From the partitions are generated stub configuration rules for each host node, which implement the workflow execution in a given host node. The stub configuration rules are provided to the host nodes. The workflow is executed by exchanging messages between the host nodes along the lines of the original workflow. The workflow may be associated with implementation of a service or it may be for the purposes of network management.Type: GrantFiled: June 9, 2006Date of Patent: June 26, 2012Assignee: Nokia CorporationInventor: Vilho Räisänen

Patent number: 7835283Abstract: The invention relates to a method for managing Quality of Service (QoS) in a packet network (10). The method comprises feeding a predetermined information flow into the packet network. (10) for measurement purposes and measuring the characteristics of said information flow by means of a continual measurement for producing QoS information. Said Qos information is used to control communications traffic in the packet network (10) in order to manage the Quality of Service (QoS) of the packet network (10). The invention further relates to a system for managing Quality of Service (QoS) in the packet network (10).Type: GrantFiled: May 2, 2001Date of Patent: November 16, 2010Assignee: Nokia CorporationInventors: Vilho Räisänen, Marko Suoknuuti, Pekka Pessi

Patent number: 7826353Abstract: A mechanism for controlling connection parameters for a communication connection between network elements is disclosed. When the communication connection is initialized, an authorization for the connection parameters of services is requested from a policy control entity which decides on connection parameters to be authorized for the communication connection and on service types which can be provided for the communication connection. A decision message is sent to a communication control network element wherein the decision message comprises the authorization for the connection parameters, service types usable for the communication connection, and an information portion indicating, for each service, whether or not the policy control entity controls a further authorization regarding at least one of the indicated service types in the communication connection. The decision message is enforced in the communication connection by the communication control network element.Type: GrantFiled: October 3, 2003Date of Patent: November 2, 2010Assignee: Nokia CorporationInventors: Zhi-Chun Honkasalo, Tuija Hurtta, Vilho Räisänen
