A mobile communication apparatus includes a mobile IP/Fast Mobile IP processing part, an access router searching part for acquiring information on access router apparatuses, a Fast Mobile IP compliance determining part for determining whether the access router apparatuses comply with Fast Mobile IP, and a Fast Mobile IP control part for controlling the contents of a message produced by the mobile IP/Fast Mobile IP processing part. In this way, even if one of the access router apparatuses does not comply with Fast Mobile IP, the procedure of Fast Mobile IP can be implemented, thereby reducing packet loss.

A home gateway device having a home agent function selects communication interfaces other than the communication interface which has acquired network information for setting a home network to be home links, and appropriately sets the home link and a home agent by using the acquired network information, thereby reliably achieving the automatization of the device setting. Moreover, the home gateway device selects a link connected to a mobile terminal based on a mobile IP as home link, acquires existing home agent information from the mobile terminal and makes settings with this information, thereby setting the home link without compelling the mobile terminal to change its setting.

In a mobile communication system utilizing Mobile IP, information on the access network is exchanged between access routers. And when a mobile terminal performs a handover, the previously exchanged information on the neighbor access routers and the access network information are provided to the mobile terminal. By so doing, the mobile terminal can determine a destination access router in advance, enabling to realize an efficient handover processing.

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.

A base station device includes a processing unit that performs a base station process on a mobile terminal and a core network device; a cellular communication unit for connection to the mobile terminal; and a connection control unit, wherein the cellular communication unit receives a connection request message for connection to an external network from the mobile terminal, the base station processing unit replaces an access point name of the connection request message with “APN-L” and transfers the connection request message to a mobility management entity when the access point name indicating a local network is other than APN-L, and the connection control unit performs a radio bearer setting process between the mobile terminal and the connection control unit, based on a context setup request message in which the “APN-L”, having a bearer established, received from the mobility management entity is stored.

Provided is a wireless terminal capable of transmitting accompanying information in an ad-hoc network to an external network in a state in which the incidence of missing information is minimized. In this device, ad-hoc communication and external communication are performed at different timings. Node function determination unit (120) determines a representative terminal shared by a plurality of terminals in every interval obtained by dividing a time axis. Wireless communication unit (130) performs ad-hoc communication in an interval in which the wireless terminal is not the representative terminal. Communication data management unit (140) stores representative terminal information indicating which of the terminals is the representative terminal, and communication history for ad-hoc communication. Output data generator (160) sends the communication history and the representative terminal information in a mutually associated state to the external network using external interface unit (150) during an interval in which the wireless terminal is the representative terminal.

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.

A router, if judging that a routing function is impossible to execute, sends out a connection instruction message including the address of a terminal on a local network terminating the relaying flow, to another router to solicit switching. The router having received the connection instruction message starts a process for connecting with an external network while executing a process for link connection with a terminal, and then sends out a connection completion notice message when the connection with both the external network and the terminal is established. This process enables the router to switch a path rapidly.

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.
