Abstract: PROBLEM TO BE SOLVED: To actualize a powerful user interface for a device having a limited user interface. SOLUTION: A computer 10 having a limited user interface 11 and a remote computer 12 having a more powerful user interface are connected to each other through a radio communication channel 16 and a common communication protocol is supported. To control the computer 10, user interface information is sent from the computer 10 to the computer 12. Input from a user is received by using the user interface of the remote computer 12 and this user input is sent to the computer 10 having the limited user interface 11 and executed there.

Abstract: PROBLEM TO BE SOLVED: To provide a technique that classifies services of an adjacent range division type in a radio local network. SOLUTION: A radio local network contains all devices including a device 10 as its part. The device 10 stores a list of identifiers relating to service servers in addition to recording of information with respect to service and its relating identifiers. In the case that lists of relating identifiers and identifiers are compared and a relating service is served by a service server listed in the identification list, it is discriminated that the service resides in the vicinity of the server. In the case that the relating service is served by the service server not listed in the identifier list, it is discriminated that the service is not resident in the vicinity of the server. The device 10 includes a network interface 25 for radio communication with the service server and a service discovery module 11 that stores recording of the information service and the relating identifier.

Abstract: PROBLEM TO BE SOLVED: To permit devices in a local network for announcing their services and discovering the service provided from another device by checking whether or not service information transmitted from another device includes information concerning itself except at making a timeout. SOLUTION: A protocol resources manager 11 triggers a transmitter 13 and transmits service information including information concerning one's own and existing devices to another device. Service information received by a receiver 14 is heard until a max. time (a timeout value), when the device 10 is selected. When making a timeout without receiving the service information by the receiver 14, it repeatedly executes the transmitter 13 to be triggered and information concerning own and existing devices to be transmitted to another device. When such a service information is received by the receiver 14 prior to the timeout, it is checked whether or not received service information includes information concerning itself.

Abstract: PROBLEM TO BE SOLVED: To provide a method, a device and a communication system for information exchange in a network spread environment. SOLUTION: An authenticated and secret session is attained. Thus, a 1st device 1 and at least a 2nd remote device 2 are used. A uni-directional radio communication channel 3 is started between the 1st device 1 and the 2nd remote device 2, a sequence is transmitted from the 1st device 1 to the 2nd remote device 2 via the uni-directional radio communication channel 3 to provide encrypted information to the 2nd remote device 2. An encrypted reply is transmitted to the 1st device 1 via a radio multiple address medium 4, by using the encrypted information for encryption.
