摘要:
Disclosed is a technique for reducing delay when a mobile communication terminal starts communication and reducing consumption of a power resource of the mobile communication terminal. An MN (mobile node) (1012) has plural interfaces (IF-1 (1030) and IF-2 (1028)). One interface IF-1 is connected to a connection point (serving PoA (1008)). When switching over from communication using the IF-1 to communication using the IF-2, the MN transmits a paging request message via the IF-1 and the serving PoA to a connection point (target PoA (1010)) attempted to connect using the IF-2. The target PoA that has received the paging request message reduces a beacon transmission cycle and sets transmission slots for the MN so that the connection of the MN can be established efficiently.

Disclosed is a technique which provides a handover processing method and the like which enable a smooth handover without service interruption and allow a desired handover to be performed. The technique includes the steps of: generating by a mobile node 100 a message including certain information to prioritize a connection of the mobile node to a desired access network among multiple access networks; transmitting the generated message from the mobile node to a base station located in the desired access network or a base station located in a currently-connected access network; and rejecting by a connection managing apparatus 104 for managing connections of the mobile node a path switching request from a base station of an access network other than the desired access network, the rejection being made according to certain information acquired through a base station that receives the transmitted message.

Disclosed is a technique to provide a QoS resource reservation method and the like, which will not generate a delay in establishing a QoS reservation and can avoid the waste of QoS resources. According to the technique, the method includes: a step of causing a mobile node 110 to send, toward a corresponding node 100, a first message to collect information for making a QoS resource reservation; and a step in which, when the mobile node detects a handover thereof during QoS resource reservation processing, the mobile node sends a second message to a path from the mobile node before the handover to the corresponding node to remove the QoS resource reservation.

A mobile communication terminal apparatus and a control method thereof wherein a smooth handoff can be quickly achieved in a seamless manner during a roaming between data communication networks of different packet exchange systems. A mobile communication terminal apparatus (100) comprising a network access unit (NAU) (101) having a network access mechanism that has been uniquely established by adjusting the specifications of hardware, software and protocols; and a MADU (Multiple Access Decision Unit) (103) that uses a set of interfaces to exchange information with the NAU (101), thereby deciding a channel to be used in a communication session, and that controls the NAU (101) corresponding to the decided channel; wherein the mobile communication terminal apparatus performs a roaming between data communication networks of different packet exchange systems.

A technique is disclosed of, when a mobile node has moved outside of a domain using a local address, enabling an old path of the mobile node in the domain to be torn down without using special means such as a STUN server. According to this technique, a MN 101 and a SANE 103 register a group to a group server 201 using a group registration request message 3001 and a group join request message 3007, respectively. When the MN 101 moves to a new location (MN 110) outside of a NAT domain 100, the MN 110 transmits a MN trigger message 3011 to the group server 201. Receiving the MN trigger message 3011 from the MN 110, the group server 201 transmits a group trigger message 3013 to all SANEs 103 in a group member list. Receiving the group trigger message 3013, the SANEs 103 tear down a state of an old path of the MN 101 before movement and release a resource thereof.
摘要:
The present invention introduces system, apparatus and method that reduce wastage of network resources and mobile phone resources. The mobile phone would indicate its status in a tracking area update message when it is connected to the device. The network can then understand from the status indication that the mobile phone is capable of delivering packets to the device, and would thus allow the server to initiate communications. An absence of the status indication would imply the mobile phone is not capable of delivering packets to the device, and the network would then disallow the server to initiate communications.

The invention discloses a technique to adequately control a handover of a user terminal in a data communication network and to decrease the number of signalings. According to this technique, when address of a user terminal (UE (101)) is not changed after a handover, UE (101) transmits a session update signaling message to carry out update processing of application session to P-CSCF 1 (121) corresponding to a location before the handover via P-CSCF 2 (123) corresponding to a location after the handover. P-CSCF 1 (121) transfers a session update signaling message to S-CSCF/AS (125) by using setup of signaling relating to UE (100) before the handover. At S-CSCF/AS (125), the application session is updated by using registration information of UE (100) before the handover.
摘要:
A technique for flexibly performing processes depending on the type of a path for providing an additional service when there are a plurality of paths for providing additional services for the same session between terminals communicating with each other over a network is disclosed. According to the technique, when a mobile terminal (MN 100) establishes a QoS path using NSIS to a corresponding node (CN 124) on different types of data communication paths, a signaling message including information (MIE) representing the path type is created and transmitted. Each node (QNE) with an NSIS QoS function, which has received the message, identifies a plurality of QoS paths by comparing the MIE, a session identifier and a flow identifier, and performs processing of the QoS paths according to control information (CI) from MNs or/and the policy which the QNE has.
