  Mobile wireless terminal deviceUSPTO Application #: 20070049270Title: Mobile wireless terminal device Abstract: An appearance of other mobile wireless station within a communication area of a second wireless communication system of a main mobile wireless station when the main mobile wireless station is in the communication area of a wireless base station of the first wireless communication system, is automatically detected. Communications with other mobile wireless station are autonomously started by a second wireless communication system and communications with the wireless base station are performed by the first wireless communication system. Communication content from the wireless base station of the first wireless communication system and communication content from the other mobile wireless station of the second wireless communication system are mutually relayed. The relay control is terminated when the other mobile wireless station moves outside the communication area of the second wireless communication system of the main mobile wireless station.

Brief Patent Description - Full Patent Description - Patent Application Claims
BACKGROUND OF THE INVENTION [0001] The present invention relates to a mobile wireless terminal device as a mobile wireless station and, more particularly, to a mobile wireless terminal device in the mobile wireless field represented by cellular phones and wireless LAN and in the ITS (Intelligent Transport System) field such as autonomous distributed-type network, in-vehicle wireless LAN, and intervehicular wireless communications and DSRC (Digicated Short Range Communications). [0002] In the case of conventional cellular phones and wireless LAN, the cellular system or hot spot system is adopted. Autonomous distributed-type network, in-vehicle wireless LAN, and intervehicular communications are, at the research and development stage and have not been put to practical use. Although DSRC technology, for which research and development is relatively advanced, has been put to practical use in the Electronic Toll Collection System, and so forth, this technology belongs to the hot spot system. [0003] Although current mobile wireless terminal applications include mobile wireless terminals of a multiplicity of types, because there is no compatibility between each of the wireless systems, the following problems exist. That is, there are problems such as the following: [0004] (1) a plurality of terminals must be carried around when various kinds of services are to be received; [0005] (2) the sharing merging of information between a plurality of systems is impossible; and [0006] (3) although there is a demand for a serviceable adhoc network for an ITS, at present, technology established for in-vehicle LAN and intervehicular communications to allow the construction of such a network does not exist. [0007] Japanese Patent Application Laid Open Nos. H2000-31895 and H8-84373 disclose a communication system that uses a mobile device as a relay device in order to broaden the area permitting communications. However, the mobile device does not constitute an adhoc network and the communication area is not extended by organically combining a plurality of different wireless systems. SUMMARY OF THE INVENTION [0008] An object of the present invention is to solve the problems (1) to (3) above by organically combining a plurality of wireless systems that are currently used or wireless systems that are expected to be used in the future. [0009] The mobile wireless terminal device as a main mobile wireless station of the present invention comprises: [0010] (1) first wireless communication portion that is capable of communicating mutually with a wireless base station in accordance with a first wireless system; (2) second wireless communication portion that is capable of communicating mutually with other mobile wireless station in accordance with a second wireless system; (3) user interface portion that permits two-way information transmission with a user; (4) first extraction portion for extracting control information from information that is received via the first wireless communication portion; (5) second extraction portion for extracting control information from information that is received via the second wireless communication portion; (6) control portion for determining an operational policy on the basis of control information that is extracted by the first and second extraction portion and user information and for emitting routing control information on the basis of the operational policy; and (7) router for controlling the route of information received via the first and second wireless communication portion and user information on the basis of the routing control information. [0011] The control portion (1) detects, when the main mobile wireless station is in the communication area of a wireless base station of the first wireless communication system other mobile wireless station comprising the second wireless communication portion has appeared in a place where is within the communication area of the second wireless communication system of the main mobile wireless station and outside the communication area of the first wireless communication system; [0012] (2) starts communications with the other mobile wireless station by the second wireless communication portion in accordance with a request from the other mobile wireless station; (3) communicates with the wireless base station of the first wireless communication system and with the other mobile wireless station of the second wireless communication system simultaneously and (4) controls the router to relay the communication content from the wireless base station of the first wireless communication system and transmit the communication content to the other mobile wireless station and to relay the communication content from the other mobile wireless station of the second wireless communication system and transmit the communication content to the wireless base station; and (5) terminates relay control when the other mobile wireless station moves outside the communication area of the second wireless communication system of the main mobile wireless station or when there is a communication termination request from the other mobile wireless station. [0013] Furthermore, the control portion [0014] (1) searches for another mobile wireless station comprising the first and second wireless communication portions in the communication area of the second wireless communication system when the main mobile wireless station moves outside the communication area of the wireless base station of the first wireless communication system; and, (2) upon detecting the other mobile wireless station, issues a relay request to the other mobile wireless station and communicate with the wireless base station of the first wireless communication system via the other mobile wireless station. [0015] The mobile wireless terminal device of the present invention permits communications by organically combining a plurality of currently used wireless systems or wireless systems that are expected to be used in the future.
