发明名称 Messaging system providing flexible roaming and method therefor
摘要 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.
