Description

MOBILE TELEPHONE COMMUNICATION SYSTEM
AND METHOD FOR TRANSMITTING INFORMATION
ASSOCIATED WITH A GEOGRAPHIC AREA TO A SUBSCRIBER
FIELD OF THE INVENTION This invention relates to communication systems and more specifically to mobile telephone communication systems including mobile stations that are operable in a plurality of identifiable, distinct geographic areas.
BACKGROUND OF THE INVENTION
The coverage areas for mobile telephone communication systems are constantly expanding. It is now common for a single mobile station to be operable in a plurality of identifiable, distinct geographic areas so that a subscriber may use the mobile station as he travels from one distinct geographic area to another, such as traveling from city to city, state to state, and/or country to country. During such travels, there may be information associated with each distinct geographic area that is of potential interest to a subscriber. For example, the methodology for making certain telephone calls, such as emergency calls, long distance calls, etc., may change from one geographic area to another. By way of further example, there may be a travel advisory or a weather bulletin associated with a particular geographic area that would be of interest to a subscriber if the subscriber is located in the particular geographic areas. As yet another example, there may be a number of important telephone numbers associated with each geographic area that is of interest to a subscriber. For example, the telephone numbers of the Embassy, local hospitals, local Red Cross, local taxi services, local police, local business office, local business numbers, local business and personal contacts, etc. associated with a distinct geographic area may all be of interest to a subscriber located in the distinct geographic area. Currently, it is typical for subscribers to obtain such information either by using local directories and assistance, or by anticipating the geographic areas in which the subscriber will travel and carrying the information with the subscriber as the subscriber travels from one geographic area to another. However,- subscribers cannot always anticipate the geographic areas to which they will travel, and locating and using local directories and assistance can take up valuable time.
SUMMARY OF THE INVENTION In accordance with the present invention, a method is provided for communicating information for use by a subscriber in a terrestrial and/or satellite mobile telephone communication system including mobile stations that are operable in a plurality of identifiable, distinct geographic areas. The method includes the steps of storing a data base containing a plurality of information sets, each information set corresponding to one of the distinct geographic areas and containing information associated with the distinct geographic area that is of potential interest to a subscriber located in the geographic area; determining a current distinct geographic area in which a mobile station is located; and transmitting the information set corresponding to the current distinct geographic area from the data base to the mobile station.
In one form, each of the information sets contain telephone numbers associated with one of the distinct geographic areas.
In one form, the method further comprises the step of storing the telephone numbers in a memory device of the mobile station for future recall and use by a subscriber using the mobile station after the transmitting step.
In one form, the method further includes the step of enabling a speed dialing function in the mobile station for at least some of the telephone numbers.
In one form, the storing step comprises storing at least some of the information in the data base in the form of voice messages that can be transmitted to a mobile station and conveyed to a subscriber through a speaker associated with the mobile station.
In one form, the storing step comprises storing at least some of the information in the data base in the form of text messages that can be transmitted to a mobile station and conveyed to a subscriber through a display associated with the- mobile station.
In one form, the method further includes the step of comparing the current distinct geographic area with a last known distinct geographic area in which the mobile station was located. The transmitting step includes the step of transmitting the information set corresponding to the current distinct geographic area from the data base to the mobile station only if the current distinct geographic area is different than the last known distinct geographic area.
In one form, the method further includes the step of storing a time data base of acceptable transmission times for the mobile station. The transmitting step includes the step of accessing the time data base for the acceptable transmission times for the mobile station and transmitting the information set corresponding to the current geographic area from the data base to the mobile station at one of the acceptable transmission times for the mobile station.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As seen in Fig. 1 , the invention is embodied in a terrestrial and/or satellite mobile telephone communication system 10 including mobile stations 12 that are operable in a plurality of identifiable, distinct geographic areas 14, 16, and 18, such as villages, towns, townships, cities, counties, states, regions, countries, and continents. The communication system 10 includes one or more switching system(s) 20, one or more memory device(s) 22 that are operably associated with- the switching system(s) 20, one or more transmitter(s) 24 and receiver(s) 25 that are operably associated with the switching system(s) 20 and memory device(s) 22 and capable of transmitting signals to any of the mobile stations 12 located in the geographic areas 14, 16, 18, and one or more control system(s) 26 that are operably associated with the switching system(s) 20, memory device(s) 22, transmitter(s) 24 and receiver(s) 25 to control the communication system 10. The switching system(s) 20, the memory device(s) 22, the transmitter(s) 24, the receiver(s) 25 and control system(s) 26 may be located within or remote from any or all of the geographic areas 14, 16, 18.
According to the invention, the communication system 10 is configured to provide a subscriber traveling between the geographic areas 14, 16, 18 with information associated with each of the geographic areas 14, 16, 18 that is of potential interest to the subscriber when the subscriber is located in one of the geographic areas 14, 16, 18. For example, the communication system 10 is configured so that when a subscriber travels from the geographic area 14 to the geographic area 16, the communication system 10 will provide the subscriber with information associated with the geographic area 16 that is of potential interest to the subscriber while the subscriber is located in the geographic area 16. It should be understood that while only three distinct geographic areas
14, 16, and 18 are illustrated for the purpose of describing the invention, the invention contemplates anywhere from two geographic areas to as many geographic areas as may be required to service the coverage area for the communication system 10. Many types of mobile station(s) 12, switching system(s) 20, memory device(s) 22, transmitter(s) 24, receiver(s) 25, and control system(s) 26 are well known and may be utilized to practice the invention with little or no modification other than to the control scheme implemented by the control system(s) 26. Accordingly, more detailed descriptions of the mobile station(s) 12, switching system(s) 20, memory device(s) 22, transmitter(s) 24, and control system(2) 26 is not required herein. It should be understood that while the switching system(s) 20, memory- device^) 22, transmitter(s) 24, receiver(s) 25, and control system(s) 26 are illustrated in Fig. 1 by separate blocks, these components 20, 22, 24, and 26 may be selectively integrated with each other, or may exist separately from each other. For example, one or more of the memory device(s) 22 may be integrated with one or more of the control system(s) 26. By way of further example, one or more of the control system(s) 26 may be integrated with one or more of the switching system(s) 20. As yet another example, one or more of the switching system(s) 20 may be integrated with one or more of the transmitter(s) 24. Again, because such integration is well known, a more detailed description is not required herein.
One example of a mobile station 12 for use in the invention is shown in Fig. 2. The mobile station 12 includes a transmitter/receiver 30; input-output devices 32, including a speaker 34 and a visual display 35; control circuitry 36; memory 38; and speed dialing circuitry 40. Many types of transmitters/receivers (30), input-output devices 32, speakers 34, control circuitry 36, memory 38, and speed dialing circuitry 40 for use in mobile stations 12 are well known and may be utilized to practice the invention with little or no modification. Accordingly, more detailed descriptions of these components is not required herein. Further, it should be understood that some of the components, such as the speaker 34, speed dialing circuitry 38 and memory 40, are not necessarily required for all embodiments of the invention.
With reference to Fig. 3, to practice the invention, a data base containing the plurality of information sets (145, 165, 185) is stored in the memory device(s) 22 as shown at block 42. Each information set 145, 165, 185 corresponds to one of the distinct geographic areas 14, 16, 18 and contains information associated with the distinct geographic area 14, 16, 18 that is of potential interest to a subscriber located in the geographic area 14, 16, 18. Examples of such information were discussed more fully in the Background of the Invention section of this application, and include, for example, the methodology of making certain telephone calls, such as emergency calls and long distance calls; travel advisories; weather reports or bulletins; and important telephone numbers, such as the * Embassy, local hospitals, local Red Cross, local taxi services, local police, local business office, local business numbers, and local business and personal contacts associated with the distinct geographic area. As shown at block 44, the control system(s) 26 is configured to determine a current geographic area in which a mobile station 12 is located. The communication system may perform this step for a plurality of mobile stations 12 to determine the current distinct geographic area 14, 16, 18, for each of the plurality of mobile stations 12. Typically, this step will be performed whenever a location update is initiated for one of the mobile stations 12. In most current communication systems, a location update is initiated whenever a mobile station 12 is powered on and whenever a mobile station 12 moves from one geographic area 14, 16, 18 to another geographic area 14, 16, 18 while the mobile station is powered on. In this regard, the communication system 10 may utilize the receiver(s) (25) to perform the location update by receiving a signal from the one mobile station 12. Alternatively, the location update may be performed by utilizing global positioning technology, many forms of which are well known and need not be described in more detail herein.
Preferably, as shown at block 46, the control system(s) 26 is configured to compare the current geographic area, as determined by the most recent location update, with the last known geographic area in which the one mobile station 12 was located, which will be the current geographic area determined from the location update that immediately preceded the most recent location update. As shown at block 48, if the current geographic area is different than the last known geographic area, the control system(s) 26 is configured to transmit the information set corresponding to the current geographic area from the memory device(s) 22, through the switching system(s) 20 and transmitter(s) 24 to the one mobile station 12. As shown at block 50, if the current geographic area is the same as the previous geographic area, the system 10 repeats the determining step after the next location update, without transmitting the information set. It should be understood that according to some alternate embodiments in the invention, the steps illustrated by- blocks 46 and 50 are eliminated so that the transmitting step illustrated by block 48 occurs every time the determining step illustrated by block 44 is performed.
According to one or more embodiments of the invention, each of the information sets 145, 165, 185 contain telephone numbers associated with the distinct geographic area 14, 16, 18 corresponding to the information set 145, 165, 185. After the transmitting step illustrated by block 48, the telephone numbers are stored in the memory 38 of the mobile station 12, as shown at block 52, and the speed dialing circuitry 40 is enabled for at least some of the telephone numbers by the controller 36 of the mobile station 12, as shown at block 54. In some embodiments, the telephone numbers stored in memory 38 overwrite the telephone numbers previously stored in memory 38 for speed dialing associated with the geographic areas 14, 16, 18. Thus, for example, a mobile station 12 could be configured so that the speed dial No. 1 always dials a local taxicab company, the speed dial No. 2 always dials the local U.S. Embassy, and the speed dial No. 3 always dials the local business office of the geographic area 14, 16, 18 in which the mobile station 12 is currently located. This allows a subscriber to access such important telephone numbers without anticipating the geographic areas to which the subscriber will travel, and without taking the time to locate and utilize local directories and assistance.
According to one or more embodiments of the invention, the storing step illustrated by block 42 includes the step of storing at least some of the information in the data base in the form of voice and/or text messages that can be transmitted to one of the mobile stations and conveyed to a subscriber through the speaker 34 and/or visual display 35 of the mobile station 12. For example, for these embodiments, a subscriber arriving in the geographic area 16 could receive a travel advisory warning the subscriber of various potential dangers associated with the geographic area, and/or providing the subscriber with a current weather forecast for the geographic area 16 or warnings of impending severe weather for the geographic area 16. The technologies required for storing and transmitting voice and/or text messages are well known and need not be described further herein. For example, - short-message service technology is well known for transmitting alphanumeric text messages.
According to one or more embodiments of the invention, the alphanumeric storing step illustrated by block 42 includes the step of storing a time data base 56 of acceptable transmission times for one or more of the mobile stations 12. The transmitting step illustrated by block 50 includes the step of accessing the time data base 56 for the acceptable transmission times for the mobile station 12 and transmitting the information set 145, 165, 185 corresponding to the current geographic area 14, 16, 18 at one of the acceptable transmission times for the mobile station 12. This feature is primarily useful with the embodiments which include information in the data base in the form of voice messages. For example, the time data base may include acceptable transmission times of 9:00 a.m. until 6:00 p.m. for one of the mobile stations 12 so that the subscriber each avoid receiving the transmission of a voice message information set during the evening and early morning hours.
The foregoing disclosure of specific embodiments is intended to be illustrative of the broad concepts comprehended by the invention.
