Mobile wireless communication terminal and communication control method
First Claim
1. A mobile wireless communication terminal, comprising:
- a first communication unit used for communication with a base station;
a second communication unit used for communication with other mobile wireless communication terminals;
a storage device storing contents data that can be used in said mobile wireless communication terminal and can be transmitted to said other mobile wireless communication terminals; and
a communication controller that obtains specific contents data by searching said storage device when said specific contents data is requested, transmitting, by packet broadcast, a request of said specific contents data to said other mobile wireless communication terminals that can communicate via said second communication unit when the valid specific contents data is not detected in said storage device, and transmitting a request of said specific contents data to said base station via said first communication unit when said specific contents data cannot be received from said other mobile wireless communication terminals, which can communicate, within a predetermined time, andwherein, when receiving a second request of second contents data by said packet broadcast from another mobile wireless communication terminal, said communication controller searches said storage device for the requested second contents data, replies with said requested second contents data to said another mobile wireless communication terminal when the valid requested second contents data is detected in said storage device, and transfers the received second request of said second contents data by said packet broadcast to other mobile wireless communication terminals when said second contents data is not detected in said storage device, andupon detecting that lack of a packet exists among packets for said specific contents data, which were received from said other mobile wireless communication terminals that are different from said base station, said communication controller causes the first communication unit to transmit a request for data of at least a lacked packet through said base station to a contents delivery computer.

Abstract
In order to improve the efficiency of the data communication between mobile wireless communication terminals having a communication means mainly used for the wireless communication between the mobile wireless communication terminals and a wireless communication means mainly with a base station, a following terminal is used. Namely, it includes: a first communication unit used for communication with a specific base station; a second communication unit used for communication with other mobile wireless communication terminals; a storage area storing content data that can be used in the mobile wireless communication terminal and can be transmitted to other mobile wireless communication terminals; and a communication controller that obtains specific content data by searching the storage area when a request of the specific content data is accepted from a user of the mobile wireless communication terminal, transmitting a request to other mobile wireless communication terminals that can communicate via the second communication unit when the valid specific content data is not detected in the storage area, and transmitting a request to the specific base station via the first communication unit when the specific content data cannot be received from other mobile wireless communication terminals, which can communicate, within a predetermined time.

13. A communication control method executed by a mobile wireless communication terminal having a first communication unit used for communication with a base station, and a second communication unit used for other mobile wireless communication terminal, said communication control method comprising:
-
searching a storage device storing contents data that can be used in said mobile wireless communication terminal and can be transmitted to said other mobile wireless communication terminals, in response to detecting that specific contents data is requested; transmitting, by packet broadcast, a request of said specific contents data to said other mobile wireless communication terminals that can communicate via said second communication unit in response to detecting that the valid specific contents data is not detected in said storage device; transmitting a request of said specific contents data to said base station via said first communication unit in response to detecting that said specific contents data cannot be received from said other mobile wireless communication terminals, which can communicate, within a predetermined time; upon receiving a second request of second contents data by said packet broadcast from another mobile wireless communication terminal, searching said storage device for the requested second contents data and replying with said second requested contents data to said another mobile wireless communication terminal when the valid requested second contents data is detected in said storage device; transferring the received second request of said second contents data by said packet broadcast to other mobile wireless communication terminals, upon detecting that said second contents data is not detected in said storage device; and upon detecting that lack of a packet exists among packets for said specific contents data, which were received from said other mobile wireless communication terminals that are different from said base station, causing the first communication unit to transmit a request for data of at least a lacked packet through said base station to a contents delivery computer.

14. A non-transitory computer-readable storage medium storing a program for causing a mobile wireless communication terminal having a first communication unit used for communication with a base station and a second communication unit used for other mobile wireless communication terminal to execute a process, comprising:
-
searching a storage device storing contents data that can be used in said mobile wireless communication terminal and can be transmitted to said other mobile wireless communication terminals, in response to detecting that specific contents data is requested; transmitting, by packet broadcast, a request of said specific contents data to said other mobile wireless communication terminals that can communicate via said second communication unit in response to detecting that the valid specific contents data is not detected in said storage device; transmitting a request to said base station via said first communication unit in response to detecting that said specific contents data cannot be received from said other mobile wireless communication terminals, which can communicate, within a predetermined time; upon receiving a second request of second contents data by said packet broadcast from another mobile wireless communication terminal, searching said storage device for the requested second contents data and replying with said second requested contents data to said another mobile wireless communication terminal when the valid requested second contents data is detected in said storage device; transferring the received second request of said second contents data by said packet broadcast to other mobile wireless communication terminals, upon detecting that said second contents data is not detected in said storage device; and upon detecting that lack of a packet exists among packets for said specific contents data, which were received from said other mobile wireless communication terminals that are different from said base station, causing the first communication unit to transmit a request for data of at least a lacked packet through said base station to a contents delivery computer.
