摘要:
A wireless communication terminal including: a switching section for switching between a first communication system in which an upper limit value of a transmission rate varies and a second communication system; a reception section for receiving an information indicating the upper limit value of the transmission rate in the first communication system, from a base station; a comparison section for making a comparison between the upper limit value received by the reception section and a predetermined reference value, either at a communication start time or during communication with the base station in the first communication system; and a control section for performing switching control of the switching section so as to perform communication in the second communication system when the upper limit value is lower than the reference value as a result of the comparison by the comparison section.
摘要:
In a control of receiving service information, a controller in a radio communication terminal (AT) controls a communication section to receive broadcast data continuously for one cycle while a broadcast service is executed. When a packet among the broadcast data can not be received for some reason, retransmission of the packet is awaited. During the waiting period, transfer rates are respectively calculated based on all previously received data and the latest data received (e.g., during the preceding 30 seconds). Then, a time until the required packet is received for the next time is estimated. Until that time, intermittent reception is performed by the radio communication terminal (AT) at an interval assigned for the radio communication terminal.
摘要:
A communication unit adapted to the EV-DO standard communicates with a base station. An acquisition unit acquires the number of communication terminals in communication with the base station. A derivation unit measures the CIR from the received pilot signal to derive a DRC value corresponding to the measurement result. A storage unit stores the number of communication terminals obtained from the acquisition unit and the CRC value derived from the derivation unit. A calculation unit calculates an estimated communication rate based on the maximum transmission rate with the base station corresponding to the DRC value, the maximum DRC value, the derived DRC value from the derivation unit, and the number of communication terminals. A comparison unit selects a base station having a high estimated communication rate as a base station to communicate.

摘要:
A radio communication terminal (AT) includes a communication section for performing a radio communication with a base station, and a controller. Before performing a handoff from a first base station to another peripheral base station while receiving service information delivered by the first base station, the controller checks a progress of sequence of the service information being received. Then, the controller performs a handoff control depending on the check result. When it is determined that reception of a packet having the sequence number being received is to be completed within a certain time as a result of checking the progress, the controller suspends the handoff until the reception of the packet is completed.
