Abstract

In a cellular communication system, the delivery of a page or message is attempted over the system to a user of the system. If the page or message is undeliverable before a set period of time, the page or message is converted to a voice mail message. The voice mail message is then stored in the cellular communication system. When the cellular communication system is accessed by the user, the user is notified of the existence of voice mail by either a text page or an automated voice radiotelephone call. The stored voice mail message is then delivered either automatically, or at the user'"'"'s request.

Claims

1. A method of delivering a text paging message in a cellular communication system, such method comprising the steps of:

paging a communication unit over said cellular communication system;

upon expiration of a paging period, converting the text paging message into a voice mail message; and

delivering the voice mail message over said cellular communication system.

2. The method as in claim 1 further comprising the step of receiving a text paging message at a base site of the cellular communication system.

3. The method as in claim 1 wherein the step of paging the communication unit further comprising transmitting a page notification from a base site on a radio frequency channel.

4. The method as in claim 1 further comprising the step of storing the voice mail message in a voice mail storage system.

5. The method as in claim 1 further comprising the step of periodically transmitting a voice mail notification message to the communication unit.

6. A method of delivering a text paging message to a cellular communication unit within a cellular communication system having a plurality of base sites, such method having the steps of:

A) transmitting a page notification from each of the plurality of base sites;

B) waiting a maximum page period for a page response from the cellular communication unit;

C) upon expiration of the maximum page period, converting the text paging message into a voice mail message and storing said voice mail message within a voice mail system; and

D) delivering the voice mail message under a voice mail format over a first base site of said plurality of base sites.

7. In a wireless communication system having a paging subsystem and a voice mail subsystem, a method of delivering a text paging message to a communication unit in said wireless communication system, said method comprising the steps of:

forwarding said text paging message to be delivered to said paging subsystem of said wireless communication system;

transmitting said text paging message from a base site of said wireless communication system;

converting said text paging message to a voice mail message unless an acknowledgment is received from said communication unit that said text paging message was received;

saving said voice mail message in said voice mail subsystem;

deleting said text paging message from said paging subsystem;

storing a voice mail notification message in said paging subsystem for transmission to said communication unit;

transmitting said voice mail notification message to said communication unit over said wireless communication system; and

retrieving said voice mail message over said wireless communication system.

8. The method of claim 7 wherein said step of transmitting said voice mail notification message is executed when said communication unit registers with said wireless communication system.
