BASE STATION DEVICE AND COMMUNICATION SYSTEM

摘要

A CPU is connected with an external RAM, so that the CPU is caused to function as a data exchange unit. When a second 3G circuit unit performs a communication process such as a process of framing a frame protocol, the CPU is caused to access the external RAM such that the data required for the communication process is provided to the second 3G circuit unit. Also, the CPU causes the data processed by the second 3G circuit unit to be stored in the external RAM. This suppresses an increase in circuit size of the second 3G circuit unit, achieving a base station device capable of communication with a communication terminal device with as little power consumption as possible.

主权项

1. A base station device configured to perform radio communication with a communication terminal device, comprising:
a communication processing unit that performs a communication process to communicate with said communication terminal device; and a data exchange unit that performs at least one of reading and storing of data from and in an external storage that temporarily stores said data, to thereby exchange said data with said communication processing unit, said data being handled in the communication process by said communication processing unit, wherein said data exchange unit is implemented by a software program.
