Method of controlling allocation of a radio resource for transmitting a radio resource allocation request

A method of controlling allocation of a radio resource for a radio resource allocation request in a base station which allocates, to a terminal, in response to the radio resource allocation request received from the terminal, a radio resource for transmitting retention data in a transmission buffer of the terminal, and which transmits to the terminal a radio resource allocation notification indicating a result of the allocation, the method comprising:

• receiving an amount of retention data in the transmission buffer from the terminal;
• determining a transmission cycle of the radio resource allocation request of the terminal so that the transmission cycle is longer when the retention amount is larger;
• and
• allocating a radio resource for the radio resource allocation request in a manner that allows the terminal to transmit the radio resource allocation request in the determined transmission cycle.

A method of controlling allocation of a radio resource for a radio resource allocation request in a base station which allocates, to a terminal, in response to the radio resource allocation request received from the terminal, a radio resource for transmitting retention data in a transmission buffer of the terminal, and which transmits to the terminal a radio resource allocation notification indicating a result of the allocation, the method comprising:

• cyclically receiving from the terminal an amount of retention data in the transmission buffer;
• obtaining a differential between a retention amount that is received this time and a retention amount that is received last time, and determining a transmission cycle of the radio resource allocation request so that the transmission cycle is longer when the differential is larger;
• and
• allocating a radio resource for the radio resource allocation request in a manner that allows the terminal to transmit the radio resource allocation request in the determined transmission cycle.

A method of controlling allocation of a radio resource for a radio resource allocation request in a base station which allocates, to a terminal, in response to the radio resource allocation request received from the terminal, a radio resource for transmitting retention data in a transmission buffer of the terminal, and which transmits to the terminal a radio resource allocation notification indicating a result of the allocation, the method comprising:

• obtaining, in a given cycle, an average data transfer rate of data transfer from the terminal to the base station;
• determining a transmission cycle of the radio resource allocation request so that the transmission cycle is shorter when the average data transfer rate is higher;
• and
• allocating a radio resource for the radio resource allocation request in a manner that allows the terminal to transmit the radio resource allocation request in the determined transmission cycle.

A base station to control allocation of a radio resource for a radio resource allocation request, the base station allocating, to a terminal, in response to the radio resource allocation request received from the terminal, a radio resource for transmitting retention data in a transmission buffer of the terminal to the base station, and transmitting to the terminal a radio resource allocation notification indicating a result of the allocation, the base station comprising:

• a receiver to receive an amount of retention data in the transmission buffer from the terminal;
• a unit to cyclically allocate the terminal a radio resource for the radio resource allocation request if the amount of retention data is zero;
• and
• a unit to determine a transmission cycle that is suited to the amount of retention data as a transmission cycle of the notification of radio resource allocation for transmitting the retention data in the transmission buffer if the amount of retention data is not zero, and stopping the allocation of a radio resource for the radio resource allocation request during cyclic transmission of the radio resource allocation notification.
