摘要： The invention relates to a method for managing the mobility of a mobile node that moves to a different network, but keeps the same IP address. It is proposed to perform route optimization by a Proxy MIP agent on behalf of the MN, thereby shortening the data-path while allowing network-based mobility. At session setup with a correspondent node, the PCC system in the home network derides whether route optimization is to be performed for the communication session. The PMIPa requests relevant information for the route optimization, including the decision for route optimization and the addresses of MN and CN, from the PCC system in the home network, when the MN attaches to the new network area. Accordingly, route optimization is performed by using the Return Routability Procedure according to MIPv6, thereby applying the MN's IP address as Home Address, and the PMIPa's address as Care-of Address of the MN.

摘要： The invention relates to a method for reducing the header size of data packets exchanged between a Mobile Node and its Home Agent. Different sort of headers are utilized between a Correspondent Node and the MN's HA, and between the MN and its HA. The sort of header used between the MN and its HA allows to reduce the header size of exchanged packets on said data path section, as only one header is necessary, compared to the necessity of two headers of the previous sort, used between the CN and the HA. To achieve this, a modified route optimization procedure is performed between the MN and its HA, wherein the HA participates in the RO on behalf of the CN. Thus, the RO remains transparent for the CN, while the MN thinks normal RO is happening. The invention also relates to several network entities that participate in the method.

摘要： The invention relates to a method for fast configuring of a default router for a mobile node in a mobile communication system. A default router is used by a mobile node to transmit outgoing data to. The mobile node moves from a first to a second network area, which are respectively connected to a first and second router. In order to update the default router, after changing an attachment of the mobile node to the network, the new second router is adapted to transmit a notification to the mobile node, for changing its default router to the new router. According to the invention, the second router may also transmit a message to inform the mobile node about an expiration of the old first router. The new router may also send a message, including an indication about a new rust-hop router for the outgoing data of the mobile node.

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 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.
