Abstract

A method for paging a high-speed subscriber by a roaming reservation in a radio paging switching system. The method includes the steps of registering a roaming area and a scheduled arrival time through a voice mail system; converting a format of the registered information and transmitting the registered information to the radio paging switching system; transmitting the registered information to a radio paging terminal so that the radio paging switching system can synchronize with the radio paging terminal in an area, a time and a frequency; and checking a timer of a corresponding area, and if a registered time elapses, storing, in a data base, information that a subscriber moves into the corresponding area, thus to provide the subscriber with a roaming service.

Claims

1. A method for paging a high-speed subscriber by a roaming reservation in a radio paging switching system having a voice mail system, comprising the steps of:

registering a roaming area and a scheduled arrival time through said voice mail system in response to voice messages from a subscriber of a radio paging terminal;

converting the registered information into a desired signal format and transmitting the registered information in said desired signal format from said voice mail system to said radio paging switching system;

transmitting the registered information from said radio paging switching system to said radio paging terminal so that said radio paging switching system can synchronize with said radio paging terminal according to time;

checking a timer of said radio paging terminal, and if a registered time elapses, and tuning said radio paging terminal at a frequency of said roaming area for readying said radio paging terminal for a wide area call; and

checking a timer of said radio paging switching system, and if the registered time elapses, said storing information that the subscriber moves into said roaming area in a data base of said radio paging switching system to provide said subscriber with a roaming service.

2. The method as claimed in claim 1, wherein said registering step comprises the steps of:

selecting a service menu in response to a first voice prompt message sent from said voice mail system to said subscriber via a telephone;

selecting a roaming area number in response to a second voice prompt message, if the selected service menu is a roaming service menu is selected;

registering a scheduled arrival time of a roaming area in response to a third voice prompt message; and

registering a scheduled departure time from said roaming area in response to a fourth voice prompt message.

3. The method as claimed in claim 2, further comprising a step of said voice mail system audibly informing said subscriber which roaming area and roaming service time has been selected.

4. The method as claimed in claim 3, further comprising a step of sending another voice prompt message to said subscriber asking whether said subscriber desires to select another area after informing said subscriber which roaming area and roaming service time has been selected, and, if another area is selected, returning to said step of selecting a roaming area number.

5. The method as claimed in claim 1, wherein said step of transmitting the registered information from said radio paging switching system to a radio paging terminal comprises converting said registered information from said desired format into a Telecator Network Paging Protocol format for transmission to said radio paging terminal.

6. The method as claimed in claim 1, wherein said step of transmitting the registered information from said radio paging switching system to a radio paging terminal comprises utilizing a high performance paging control rack interface to convert said registered information from said desired format into a Telecator Network Paging Protocol format for transmission to said radio paging terminal via a high performance paging control rack and a high-speed base station.

7. A paging system comprising:

a voice mail system;

a radio paging switching system comprising;

a voice mail system interface for interfacing with said voice mail system;

a public switched telephone network interface for interfacing with a telephone via a public switched telephone network;

a paging call processor for determining whether a current call is a call for a low-speed subscriber or for a Flex™

high-speed subscriber and processing a corresponding paging call;

a base station interface for interfacing said radio paging switching system with a low-speed base station;

a high performance paging control rack interface for interfacing said radio paging switching system with a high performance paging control rack; and

a wide area call processor for transmitting a message and subscriber information to all registered areas, and for receiving a wide area call message from a wide area network to detect a radio frequency channel number;

said high performance paging control rack for coding paging data to Flex™

receiving protocol;

a high-speed base station for receiving the Flex™

receiving protocol coded data and transmitting the Flex™

receiving protocol coded paging data to a high-speed transmitter; and

said high-speed transmitter paging a radio paging terminal by the Flex™

receiving protocol.

8. The paging system as set forth in claim 7, further comprising:

said voice mail system transmitting voice prompts to a subscriber of said radio paging terminal and registering a roaming area and a scheduled arrival time in response to voice messages from said subscriber.

9. The paging system as set forth in claim 8, further comprising:

said voice mail system converting the registered information into a desired signal format and transmitting the registered information in said desired signal format via said voice mail system interface to said paging call processor.

10. The paging system as set forth in claim 9, further comprising:

said paging call processor storing information regarding the subscriber who has registered the roaming area and time as a wide area registration subscriber in a data base, and transmitting the roaming area and time to the high performance paging control rack interface.

11. The paging system as set forth in claim 9, further comprising:

said high performance paging control rack interface converting said registered information from said desired format into a Telecator Network Paging Protocol format for transmission to said high performance paging control rack.
