摘要： Disclosed is a technique to provide a handover method that can improve the communication efficiency by reducing tunnel overhead between a mobile node and a home agent. When the mobile node (UE) (107) performs handover (HO) from a first access router (104) to a second access router (105) and if the IP versions supported by the networks before and after the HO are different, the UE transmits a first message including an allocation request for a home address of the HO target to the home agent (HA) and a second message including an address allocation request. The HA transmits to the UE, a third message including the home address of the HO target based on the allocation request and transmits to the UE, a fourth message including the home address based on the address allocation request.

摘要： The invention relates to a method for informing two access gateways about each other's presence and identity, in order to establish a data path between them, thereby shortening the overall data path of data packets exchanged between two mobile nodes (MN), that are located in different networks. In particular, each access gateway is provided with the other gateway's address and additionally with the other MN's address for forwarding by the access gateway those data packets destined to the other MN to the other access gateway. A combination of Session Initiation Protocol messages (Invite and Ringing) and route optimization messages are used, so as to confer the information on the gateway's ID and MN's address to the gateways.

摘要： A technique is disclosed, according to which the efficiency of a communication channel where the communication is performed between radio communication terminals. According to this technique, under the network condition where different types of connection can be made to different types of networks, radio communication terminals performing communication with each other can perform communication by being connected to the same access network. For instance, by changing the connection of UE_a310a, which performs communication with UE_b310b from eNB 150 to AP b230b, the communication channel of UE_a and UE_b can be changed from a channel 350 to a channel 360. Further, by turning back the channel at PDG 210, for instance, the communication channel can be shortened.

摘要： 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.

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.
