A registration checking apparatus () determines, for a target transaction, whether a relation between the number of times scanning actions are performed and the number of products registered as checkout targets satisfies a predetermined condition. The scanning action is detected by analyzing a video (). The registration checking apparatus () performs predetermined output processing when the relation does not satisfy the predetermined condition. The predetermined condition is a condition being satisfied when the number of registered products is equal to or greater than the number of detected scanning actions.

In a communication service handover system, a communication service used by a user by a first communication device is continuously used by a second communication device, and said first communication device and said second communication device are distinct from each other. The communication service handover system includes a socket update request block configured on said first communication device to request said second communication device to update a socket; a first socket control block configured on said first communication device to close a socket; and a second socket control block configured on said second communication device to apply socket information received from said first communication device.

It is difficult to perform handover between mobile terminals. In addition, when a session handover is performed between terminals whose mobilities are managed by individual Mobile IP HAs, it is difficult for an IETF standard to normally treat an Uplink packet. A network system includes: a functionthat manages bind information between terminals which are arranged in a network and are subjected to the control of a user; a functionthat translates an address; a functionthat performs encapsulation between HAs; and a function that is provided in a terminal and transmits the bind information and a handover trigger to the bind information management function

Method of performing session handover between terminals, network system, and program

A local network connecting system includes a first local network, a second local network, a mobile terminal. The first local network is connected with a gateway and a first server assigned with a first local address. The second local network is connected with a second server. The mobile terminal VPN 'Virtual Private Network'-connect to the second server through the first local network. The gateway provide mapping of local address for a terminal connected to the first local network. When a packet is sent to the first server from mobile terminal, the mobile terminal assigns a second local address unused over the VPN-connection to a destination address of the packet instead of the first local address, and transmits the packet to the gateway. The gateway translate the second local address into the first local address as destination address of the packet, and transmits the packet to the first server based on the translated destination.

Provided is a technique for switching a session between a terminal and a network to a session using a plurality of peripheral terminals having respective functions, by considering the load on the distribution side system and distributing a packet to the plurality of peripheral terminals. This application for relaying a packet transmitted from a distribution node via a communication device in response to a request from a terminal to a relay destination peripheral terminal that becomes a relay destination, characterized in comprising: data acquiring means for decapsulating the packet encapsulated by the communication device, thereby to acquire a payload data; outputting means for outputting the acquired data by the data acquiring means to a predetermined reproduction function; and relay processing means for, based upon header information being contained in the decapsulated packet, relaying the decapsulated packet to the relay destination peripheral terminal.

An authentication system according to the present invention includes an AAA server configured to be connected to the mobile network; a terminal device configured to be connected to the mobile network and be authenticated by the AAA server; and a PC configured to be connected to the terminal device through a short distance radio communication network. The PC transmits an identification data for identifying the PC itself to the terminal device through the short distance radio communication network. The terminal device authenticates the PC to access the mobile network on the basis of the identification data, and transmits an authentication data for accessing the mobile network to the AAA server. The AAA server performs an authentication that the PC accesses to the mobile network by using the authentication data. The authenticated PC accesses the mobile network through the Internet.

Authentication system, authentication method and authentication data generation program

A wireless LAN access point receives a destination URL from a mobile terminal and provides the destination URL to an authentication switch. The authentication switch is connected to an authentication gateway associated with the destination URL and provides the destination URL to the authentication gateway. The authentication gateway connected to the authentication switch causes an authentication server associated with the destination URL to perform authentication of the mobile terminal (). After the authentication server authenticates the mobile terminal (), the authentication server provides an IP address to the mobile terminal (). The mobile terminal is thus connected to the content server specified by the URL.

Network connection system, network connection method, and switch used therefor

When transmitting or receiving packets of mobile terminals for which movement information is managed by control devices, path costs that result from data-related factors for transmitting and receiving packets are calculated for each of paths that pass by way of the control devices and paths that do not pass by way of the control devices, processing costs that result from control-related factors for transmitting and receiving packets are calculated for each of paths that pass by way of the control devices and paths that do not pass by way of the control devices, the path costs and the processing costs that have been calculated are added for each of the paths that pass by way of the control devices and paths that do not pass by way of the control devices, the path for which the added cost is lowest is selected, and the transmission and reception of packets is carried out using the selected path.

Mobile communication control method, mobile communication system, router, and program

A general packet radio service (GPRS) system includes radio network controllers (RNC), support nodes (SGSN) and a gateway node (GGSN) connected in a hierarchical order for packet transmission between mobile stations in the system. Each of each RNC, each SGSN and GGSN has a communication path controller to return the request of coupling toward subordinate node or controller if the subordinate mobile stations include the destination mobile station. Accounting for the packet service is based on the return of the packets.
