Abstract

A method for sharing memory in a digital cordless telephone merged with a radio paging receiver. In the method, paging data is read from a second memory of the radio paging receiver, and a telephone number is edited by deleting data other than the telephone number from the paging data. The edited telephone number is stored in a first memory of the digital cordless telephone. To store the telephone number, it is checked whether a first memory of the cordless telephone has a spare storage area for storing a telephone number. If the first memory does not have the spare storage area, it is checked again whether a second memory of the radio paging receiver has a spare storage area. As a result, if the second memory has the spare storage area, the telephone number is stored in the second memory. However, the second memory does not have the spare storage area, the telephone number is overwritten in the first memory.

Claims

1. A method for sharing memory in an integrated digital cordless telephone and radio paging receiver, comprising the steps of:

determining whether a cordless telephone memory has a spare storage area for storing a telephone number;

determining whether a radio paging receiver memory has a spare storage area, when the cordless telephone memory does not have the spare storage area, and

storing the telephone number in the radio paging receiver memory, when the radio paging receiver memory has the spare storage area.

2. The method as claimed in claim 1, further comprising the step of:

overwriting the telephone number into the cordless telephone memory, when the radio paging receiver memory does not have the spare storage area.

3. The method as claimed in claim 1, further comprising the step of:

storing address information of the stored telephone number in the cordless telephone memory.

4. The method as claimed in claim 1, wherein said step of determining whether the radio paging receiver memory has a spare storage area further comprises the step of sending a request to a controller in the paging receiver to check the radio paging receiver memory.

5. A method for sharing memory in an integrated digital cordless telephone and radio paging receiver, comprising the steps of:

determining whether a radio paging receiver memory has a spare storage area for storing paging data upon receipt of said paging data;

determining whether a digital cordless telephone memory has a spare storage area, when the radio paging receiver memory does not have the spare storage area, and

storing the paging data in the digital cordless telephone memory, when the digital cordless telephone memory has the spare storage area.

6. A memory sharing method as claimed in claim 5, further comprising the step of:

overwriting the paging data into the radio paging receiver memory, when the digital cordless telephone memory does not have the spare storage area.

7. The method as claimed in claim 5, further comprising the step of:

storing address information of the stored paging data in the radio paging receiver memory.

8. The method as claimed in claim 5, wherein said step of determining whether the digital cordless telephone memory has a spare storage area further comprises the step of sending a request to a controller in the digital cordless telephone to the check the digital cordless telephone memory.
