In a wireless selective call receiver, a receiving section receives a wireless selective call signal including a selective call signal and subsequent a message signal and destined to the wireless selective call receiver, and then, decodes the received wireless selective call signal to produce the message signal. A storage section includes an alarm message storage region for storing alarm message signals and a normal message storage region for storing normal message signals. An informing section informing an alarm at an alarm time set in each of the alarm message signals which are stored in the alarm message storage region. A detecting section detects that the received message signal is a new alarm message signal or a new normal message signal. A write section writes the new normal message signal in the normal message storage region when the received message signal is the normal message signal. On the other hand, the write section selectively writes the new alarm message signal in one of the alarm message storage region and the normal message storage region based on a number of the alarm message signals stored in the alarm message storage region and a protection attribute of each of the alarm message signals from a delete operation. |

DETAILED DESCRIPTION The present invention is made in the light of the above-mentioned circumstances.
An object of the present invention is to provide a method for protecting an important alarm message signal and a wireless selective call receiver for the same.
In order to achieve an aspect of the present invention, a wireless selective call receiver includes a receiving section for receiving a wireless selective call signal including a selective call signal and subsequent a message signal and destined to the wireless selective call receiver and for decoding the received wireless selective call signal, a storage section having an alarm message storage region for storing alarm message signals and a normal message storage region for storing normal message signals, an informing section for informing an alarm at an alarm time set in each of the alarm message signals which are stored in the alarm message storage region, a detecting section for detecting whether the received message signal is a new alarm message signal or a new normal message signal, and a write section for writing the new normal message signal in the normal message storage region when the received message signal is the normal message signal, and for selectively storing the new alarm message signal in one of the alarm message storage region and the normal message storage region based on a number of the alarm message signals stored in the alarm message storage region and a protection attribute of each of the alarm message signals from a delete operation.
In this case, the storage section includes an attribute region for storing the protection attribute for each of the alarm message signals, and the write section refers to the attribute region to write the new normal message signal in the storage section.
The wireless selective call receiver desirably further includes an allocating section for allocating the protection attribute to the alarm message signals in the alarm message storage region including the new alarm message signal
