A determination unit (101) determines, on the basis of the information of a first network (111) used to acquire a communication application and a communication state including a communication method used for acquisition, a network usable by the communication application using a criterion prepared in advance. For example, the determination unit (101) determines a second network (112) as a network usable by the communication application. A communication unit (102) executes communication by the communication application using the network determined by the determination unit (101). For example, the communication unit (102) executes communication by the communication application using the second network (112) determined as usable.

A relay device which can store acquired information in the case where it relays a communication is provided. The relay device of the present invention is provided with: a first connecting means for connecting with a first communication device; a second connecting means for connecting with a second communication device; and a relaying means which is connected with the first communication device using the first connecting means and is connected with the second communication device using the second connecting means, for relaying first information which is communicated between the first communication device and the second communication device, and outputting second information which is all or a part of the first information.
摘要:
Collation information (22) of data (21) is acquired via a high-secure network (3). The data (21) is acquired via a low-secure network (4). The acquired collation information (22) and data (21) are collated. If the collation result is “match”, it is determined that the low-secure network (4) is not disguised, and access to the low-secure network (4) is permitted. The use of the downloaded data (21) on the high-secure network (3) and low-secure network (4) is permitted.

摘要:
The present invention provides a communication device which can perform a routing process by selecting the optimum network without preparing a statically generated connection profile. A communication detection unit detects the start of communication by a communication unit, and activates a network selection unit. The network selection unit checks an application characteristic database on the basis of a parameter from the communication detection unit, and refers to a corresponding application characteristic. The network selection unit refers to a network characteristic database, and selects the optimum network. The communication unit connects the optimum network on the basis of the selection result. When the communication application starts communication, the communication detection unit notifies the communication contents learning unit of the communication contents. The communication contents learning unit analyzes the communication contents and acquires statistics, and updates the information about the application characteristic database.
摘要:
A refresh register stores disable block information indicating a memory block whose refresh operation is to be disabled. A refresh control circuit periodically executes the refresh operation of a memory block except the memory block corresponding to the disable block information. During an access cycle to one of the memory blocks, the register control circuit writes the disable block information to the refresh register according to an external input. Consequently, in order to rewrite the refresh register, it is not necessary to use an additional operation cycle to the access cycle. Since there is no need to insert an extra operation cycle, it is possible to change a memory area to be refreshed without lowering effective efficiency of access cycles. As a result, power consumption can be reduced.
