A method and system for flow mobility filter rule verification is provided. According to an embodiment of the present invention, a network node of a telecommunications packet network is configured to receive filter rules provided by a user entity (UE) relating to a requested IP-CAN session. The filter rules are applied by a Policy and Charging Control (PCC) network architecture for the session. The network node is also configured to compare received filter rules with Inter-Mobility Policies (IMPs) of the user in order to determine if the filter rules match with the user's IMPs, and to send a filter rule verification response indicating whether or not the filter rules match the user's IMPs.

Flow mobility filter rule verification

The invention deals with managing handovers between access networks in a packet data communication environment. According to the invention, the possibility to control access network resources will improve by having a mobility manager node () managing such handovers. The mobility manager node will decide to handover a mobile node () from a first access network () to a second access network () based on received information relevant to the handover process. After the decision, the mobility manager node will instruct a home agent () or similar node to register a new care-of address or other locator of the mobile node's point of attachment, which is valid in the second access network and which can be used for contacting the mobile node in the second access network. The mobility manager node will thereafter instruct the mobile node to de-attach from the first network and attach to the second network. The invention will be especially advantageous for mobile operators managing a communication environment with heterogeneous networks, such as WLAN and WCDMA networks.

Method and a network node for managing handovers in a packet data communication environment

In conducting a communication session via an IP-based communication network, where access to the communication network can be obtained via a plurality of bearers (), a plurality of packet flows associated with a communication application () can be routed on respective ones of the bearers simultaneously.
