    摘要: The invention relates to a method for ensuring IP session continuity upon a handover of a mobile node to a non-3GPP network, wherein an ongoing IP session of the mobile node goes via a packet data network gateway. For non-3GPP networks it is necessary to discover a security gateway and to then establish the corresponding tunnels to the ePDG to form the new data path; a security tunnel between the mobile node and the security gateway, and an IP tunnel between the packet data network gateway and the security gateway. In order to prepare the handover to possible non-3GPP accesses, the two tunnels are pre-established, however maintained deactivated until their use is actually needed. Accordingly, when handing over to the non-3GPP network, the IP session may be continued without any significant interruption by activating the already established tunnels.

    摘要: The invention relates to optimizing a data path between two communication nodes. A route optimization agent (ROA) is determined in the current network of the second communication node, preferably on the data path between the two communication nodes. Then, an IP tunnel is established between the first communication node and the ROA, the IP tunnel and the corresponding security association of said IP tunnel being based on the home address of the first communication node in its home network. The first communication node may have two IP tunnels based on the same home address, one to its home agent and one to the ROA. Corresponding routing entries and binding cache entries need to be established in the ROA and the first communication node so that all data packets between the two communication nodes are exchanged via the established IP tunnel over the ROA.

    摘要: The invention relates to a method for performing a handover of a mobile node (MN) from a source to a target network, wherein a handover proxy node (HPN) is used to relay the handover of the MN to one of previously measured cells. The MN discovers an appropriate HPN and triggers the handover to the HPN by reporting the measurements together with the HPN ID as destination of the handover. When receiving the Handover Initiation message for handing over the MN to the HPN, the HPN will not proceed with the handover but adapts said handover to indicate a handover of the MN from the HPN to the target base station. Upon receiving the Handover Initiation message in the target network, system resources are configured for data forwarding between the source and target network, and for the data path used by the MN when attaching to the target base station.

    摘要: The present invention relates to an improved method for handover of a mobile node from E-UTRAN to UTRAN in a scenario where SMS is the only service of the mobile node. The improved handover method allows saving radio resources by establishing the signalling connection for SMS exchange in the target network, and avoiding the data connection in the target network, since it is not used. The MME takes the decision to establish or not the data connection in the target UTRAN, and accordingly instructs the SGSN and UE to set the corresponding PDP contexts for the data connection to a “preserved” state, so as to avoid the establishment of same. Embodiments further relate to improved SMS delivery for IDLE mode UEs that activate ISR so as to avoid the involvement of the MSC server. Instead, packet-switched domain nodes are to be involved only.

    摘要: Methods for detaching a mobile terminal from a mobile communication network. Furthermore, the invention also relates to a mobile terminal and a mobility management entity that perform these methods. The invention is inter alia applicable to a 3GPP LTE-A system following the Evolved Packet System (EPS) architecture. The invention proposes that the detach procedure of a mobile terminal is triggered by the mobile terminal being transferred into idle state. The mobility management entity can trigger the detach procedure in response to this event. The detach procedure may be deferred by a given time span. A detach timer may be configured in the mobile terminal and the mobility entity for this purpose, and upon expiry of the detach timer in the mobile terminal and the mobility management entity, both silently delete the context information related to the mobile terminal's user plane and control plane to detach the mobile terminal.

    摘要: The invention relates to a method and mobile node capable of detecting whether or not the network to which the mobile node is attached is using a network-based mobility management function for the mobile node or not. In order to enable a mobile node to detect whether the network is using a network-based mobility function for the mobile node, upon establishment of a PDN connection or IP session, the mobile node sends a probe message to the network destined to itself and determines based on the modifications of the probe message returned to the mobile node whether the network is using a network-based mobility function for the mobile node or not.
