Messaging system providing flexible roaming and method therefor
First Claim
1. A message transmission system providing flexible roaming capability toa receiving device which includesa code memory which stores addresses of a first type and an address of a second type to identify the receiving device, the addresses of the first type enable reception of messages associated with each of the addresses of the first type when the receiving device is operating within a local geographic area, andthe address of the second type enables reception of the messages associated with each of the addresses of the first type when the receiving device is operating within a different geographic area,said message transmission system comprising:
- a controller for controlling transmission of the messages associated with each of the addresses of the first type when the receiving device is operating within the local geographic area;
a transmitter, located within the local geographic area, for transmitting each of the addresses of the first type with messages associated therewith;
said controller further controls a conversion of each of the addresses of the first type to the address of the second type when the receiving device is operating within the different geographic area, wherein said controller transfers the address of the second type and the messages associated each of the addresses of the first type having messages associated therewith to a transmitter located in the different geographic area in which the receiving device is operating; and
said transmitter located within the different geographic area in which the receiving device is operating transmits the address of the second type with the messages associated with the addresses of the first type.

Abstract
A message transmission system (100) and method for providing flexible roaming to a receiving device (126) which includes a code memory (422) which stores addresses of a first type (1202) to enable reception of messages within a local geographic area, and an address of a second type (1214) to enable reception of the messages within a different geographic area. The message transmission system (100) includes a transmitter (SSID1) which transmits the addresses of the first type with the messages associated therewith within the local geographic area, and a controller (204) which controls conversion of the addresses of the first type to the address of the second type, and transfer of the address of the second type with the messages associated with the addresses of the first type to a transmitter (SSID2-SSID5) which transmits the address of the second type with the messages associated therewith to the receiving device when operating within the different geographic area.

2. A method for providing flexible roaming capability to a receiving device
which is assigned addresses of a first type and an address of a second type, the addresses of the first type enable reception of messages associated with the addresses of the first type when the receiving device is operating within a local geographic area and the address of the second type enables reception of the messages associated with each of the addresses of the first type when the receiving device is operating within a different geographic area, said method comprising the steps of: -
transmitting the addresses of the first type with the messages associated therewith to the receiving device when the receiving device is operating within the local geographic area; converting each of the addresses of the first type with the messages associated therewith to the address of the second type, when the receiving device is operating within the different geographic area; transferring the address of the second type and the message associated with each of the addresses of the first type which have messages associated therewith to a transmitter located in the different geographic area in which the receiving device is operating; and transmitting the address of the second type with the messages associated with the addresses of the first type having messages associated therewith within the different geographic area in which the receiving device is operating. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12)
