The mobile radio communication system which possesses radio resource joint ownership function

摘要

2nd communication between the plural 2nd portable terminals which utilize the ad hoc mode which communicates the aforementioned radio base station which utilizes the infrastructure mode which does the communication which it is concentrated is controlled on the basis of the scheduling of radio base station and with 1st communication between the 1st portable terminals and with the decentralized control autonomous, being the mobile radio communication method of sharing the radio resource; The aforementioned radio base station exists the aforementioned 1st portable terminal inside the area where, depending upon the aforementioned radio base station is appointed in the timing which, is in the radio wave range of access from the aforementioned 1st portable terminal communicates the aforementioned ad hoc mode which 2 in the aforementioned 2nd portable terminal which, is not utilized in 1st communication of the aforementioned infrastructure mode available or is utilized in 1st communication to notify the radio resource which to 2nd communication of the ad hoc mode which periodically, with the aforementioned 2nd portable terminal, the radio resource for the aforementioned 1st communicationIn order not to be utilized, controlling, you evade interference.
