20080205267 | Service Differentiation in the IP Multimedia Subsystem Utilizing Context-Aware Signaling - A system and method for service differentiation enabling a user to express the level of importance of a session being established and change the level during the session while satisfying QoS profiles. An extension of the 3GPP IMS architecture includes a Session Prioritization Function (SPF) in communication with a S-CSCF and a Context Information Base (CIB) which provides network contextual information. Upon receiving a session initiation or change request, the S-CSCF queries the SPF for a resource allocation/deallocation decision. The SPF consults session prioritization policies and the contextual information to make an informed decision. If the load on the IMS network is normal or light, the SPF utilizes an upper limit policy to limit resources for each service class. Otherwise, the SPF limits the size of multi-party sessions and utilizes soft and hard preemption to transfer network resources between classes. The SPF may trigger the S-CSCF to re-negotiate media-format parameters if network contextual information changes. | 08-28-2008 |
20090019056 | Method, Sensor Network, and Sensor Node for Accessing Sensed Data - There is provided a sensor node, a network, and a method for accessing data from a sensor service. Sensor nodes comprise information related to sensor service(s) they provide and to services provided by other sensor nodes of the network, including description of external sensor services, the address of the sensor nodes providing the external sensor services, and identification of the service owner. When a sensor node receives a request for a sensor service from a requester, it determines that it does not support the sensor service, and further identifies another sensor node that supports the sensor service. Then, in a first variant, the sensor node returns to the requester the other sensor node's identification so that the requester can request the sensor service. In another variant, the sensor node requests from the other sensor node data related to the requested sensor service, and transmits it to the requester. | 01-15-2009 |
