MOBILE COMMUNICATION SYSTEM AND ONBOARD TERMINAL
First Claim
1. A mobile communication system comprising:
- at least one onboard terminal that is used in a vehicle; and
at least one service provider terminal that wirelessly communicates with the onboard terminal to perform a series of processes for providing a predetermined service to the onboard terminal,wherein the service provider terminal includesa provider service channel communicator that communicates with the onboard terminal to provide the service by using any one of a plurality of preassigned service channels, anda provider control channel communicator that distributes service initiation information for initiating communication on the service channel by using a preassigned control channel, the control channel being different from the service channels;
wherein the service initiation information includesservice type information that indicates type of the service,service channel information that enables the onboard terminal having received the service initiation information to identify, of the plurality of service channels, the service channel used for the service provider terminal to communicate with the onboard terminal, andtarget terminal information indicative of a condition for the onboard terminal targeted for the service,wherein the onboard terminal includesan onboard control channel communicator that communicates with the service provider terminal by using the control channel and receives at least the service initiation information,an onboard service channel communicator that communicates with the service provider terminal by using one of the plurality of service channels determined by the service channel information included in the service initiation information received by the onboard control channel communicator,a service memory that memorizes type of service available to the onboard terminal itself,a service type determiner that determines, based on the service type information included in the service initiation information and on the type of service available to the onboard terminal itself stored in the service memory, whether the service provided by the service provider terminal is available to the onboard terminal itself,a determination information acquirer that acquires determination information, the determination information being information about the onboard terminal itself and used to determine whether the onboard terminal itself is an onboard terminal targeted for the service from the service provider terminal, anda service target determiner that determines, based on the target terminal information included in the service initiation information and on the determination information acquired by the determination information acquirer, whether the onboard terminal itself is the onboard terminal targeted for the service,wherein;
when the service type determiner determines that the service provided by the service provider terminal is available to the onboard terminal itself and the service target determiner determines that the onboard terminal itself is the onboard terminal targeted for the service, the onboard service channel communicator initiates communication with the service provider terminal by using the service channel; and
when the service type determiner determines that the service provided by the service provider terminal is not available to the onboard terminal itself or when the service target determiner determines that the onboard terminal itself is not the onboard terminal targeted for the service, the onboard service channel communicator does not initiate communication with the service provider terminal by using the service channel.

Abstract
A mobile communication system is provided. A service provider terminal distributes service initiation information by using a control channel. Upon receipt of the service initiation information, an onboard terminal determines, based on service type information included in the service initiation information and available service type stored in the onboard terminal, whether the service provided by the service provider terminal is available to the onboard terminal itself. The onboard terminal determines, based on target terminal information included in the service initiation information and determination information acquired by the onboard terminal, whether the onboard terminal itself is an onboard terminal targeted for the service.

7. An onboard terminal that performs a series of processes to receive a predetermined service by wirelessly communicating with a service provider terminal adapted to provide the predetermined service, the onboard terminal comprising:
-
an onboard control channel communicator that communicates with the service provider terminal by using a preassigned control channel and receives service initiation information distributed from the service provider terminal; and an onboard service channel communicator that communicates with the service provider terminal by using one of a plurality of preassigned service channels, the service channels being different from the control channel, wherein the service initiation information includes service type information that indicates type of the service provided by the service provider terminal, service channel information that enables the onboard terminal to identify, of the plurality of service channels, the service channel used for the service provider terminal to communicate with the onboard terminal, and target terminal information that indicates a condition for a communication terminal targeted for the service, wherein the onboard terminal further comprises a service memory that stores type of service available to the onboard terminal itself, a service type determiner that determines, based on the service type information included in the service initiation information and on the type of service available to the onboard terminal itself stored in the service memory, whether the service provided by the service provider terminal is available to the onboard terminal itself, a determination information acquirer that acquires determination information, the determination information being information about the onboard terminal itself and used to determine whether the onboard terminal itself is a communication terminal adapted to receive the service from the service provider terminal, and a service target determiner that determines, based on the target terminal information included in the service initiation information and on the determination information acquired by the determination information acquirer, whether the onboard terminal itself is a communication terminal targeted for the service, wherein; when the service type determiner determines that the service provided by the service provider terminal is available to the onboard terminal itself and the service target determiner determines that the onboard terminal itself is the communication terminal targeted for the service, the onboard service channel communicator initiates communication with the service provider terminal by using one of the service channels determined by the service channel information included in the service initiation information; and when the service type determiner determines that the service provided by the service provider terminal is not available to the onboard terminal itself or when the service target determiner determines that the onboard terminal itself is not the communication terminal targeted for the service, the onboard service channel communicator does not initiate communication with the service provider terminal by using the service channel determined by the service channel information included in the service initiation information, the service channel being one of the plurality of service channels.
