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.

The present invention introduces a method for the network to optimize the route for user's local IP access, without affecting the access to operator's core network. With this mechanism, no excessive signalling is needed for the optimization. The present invention is also applicable to the corporate network that has multiple home NodeBs or home eNodeBs. Finer grain control on the services to be provided over different home NodeB or home eNodeB is also possible. Further, path optimization and continuation of the service upon handover can be controlled, and hence flexibility of the service can be secured.

The present invention introduces a method for managing the route to be used for the user's local device access traffic through the use of intelligent switching performed by the breakout node (eNodeB, home NodeB, or home eNodeB) together with the local access gateway node of the local service domain. Essential information pertaining to performance of this intelligent switching is obtained through the communication of specific tokens using selected channels of communication. A variety of combinations pertaining to the setup, selection and composition of token and channel is possible and described.

Provided is a technique to provide a handover processing method that allows a mobile terminal to be handed over seamlessly while preventing occurrence of double reservation. The method includes a step where a mobile terminal (100) decides to connect to a desired access network (113) and detects the possibility of occurrence of a network-initiated handover processing performed by a predetermined device of the communication network as one of the controlling entities, and a step where the mobile terminal transmits a connection request message requesting a connection to the desired access network, the connection request message including information to maintain the connection with the access network with which the mobile terminal is currently connecting, to a base station disposed in the desired access network based on a detection result of the detection step.

Disclosed is a technique to provide a handover processing method to avoid a failure in both of the handovers and enables communication via an access network as a UE initiated handover target that is originally optimal. The handover processing method includes: a step where a mobile terminal (100) connected with a first access network (111) transmits a connection establishment request message requesting a connection with desired a second access network (113) to a base station (107) placed in a second access network; a step where the mobile terminal determines whether a predetermined event occurs or not; a step where, when the mobile terminal determines that the predetermined even occurs, generates a reconnection request message including first flag information to the second access network; and a step where the mobile terminal transmits the generated reconnection request message to the base station in the second access network.

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 provides a method for trust relationship detection between a core and access network for a user equipment. The gist is that a security tunnel establishment procedure is used so one entity, be it part of the core network or be it the user equipment itself, is provided with information to determine whether the access network is trusted or untrusted. The information may comprise a first IP address/prefix, which is initially assigned to the user equipment, upon attaching to the access network. The necessary information may further comprise a second IP address/prefix, which is an address/prefix that is allocated at a trusted entity of the core network. Depending which entity determines the trust relationship of the access network, it might be necessary to transmit either the first IP address/prefix or the second IP address/prefix or the first and the second IP address/prefix using the security tunnel establishment procedure.
