The invention discloses a storage method applied to wireless communication and a reading and writing storage device. The method comprises the steps as follows: according to data business types, corresponding pointer migration is selected for adjusting a storage structure, storage space is self-adaptively allocated, a corresponding pointer is read under the condition of write operation, whether the storage space is in a non-space upward merging state is judged according to the state indication, if yes, the corresponding storage space is found out according to the read pointer, data write operation is executed, and otherwise, odd/even judgment of the pointer is performed. According to the invention, the comprehensive performance and the utilization ratio of the storage space are improved.
