DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention relates to a public cellular telephone network that includes public cellular telephones having a four-button telephone operation interface, a method for collecting statistical information about cellular public phone use and performance metrics, a method for management of a large number of cellular public telephones and telephone theft notification.
The principles and operation of public cellular telephones and a public cellular telephone network according to the present invention may be better understood with reference to the accompanying description.
By way of introduction, the following description relates to a non-mobile fixed-cellular telephone having two SIM cards. The primary SIM card is substantially non-removably installed in the cellular telephone. A secondary SIM card is inserted by a user when the user wishes to use the public cellular telephone. The primary SIM card is preferably configured to provide communication between the individual telephone and the network server so as to provide the service provider with data for servicing and management needs. Further, the primary SIM card may also provide a limited level of telephone use such as but not limited to calls to police, fire and other emergency numbers, and to a network "operator". Preferably, the secondary SIM card is configured as part of a pre-paid telephone use card. Therefore, innumerable users may, one at a time, activate the public cellular telephone for use.
Along with providing an exclusive telephone number for each user, the secondary SIM card may include other telephone use information that is unique to each individual user such as, but not limited to, name, phone book, incoming and outgoing call information and a backlog of SMS messages. Therefore, the cellular public telephone of the present invention relates to each user as a unique individual and as long as the user's secondary SIM card is inserted into the cellular public telephone of the present invention, the phone acts as his/her personal cellular telephone.
The public cellular telephone and cellular telephone network of the present invention provide a number of innovative features that will be described in greater detail herebelow. These features include a method for collecting statistical
information about cellular public phone use and performance metrics, a method for management of a large number of cellular public telephones, a four-button telephone operation interface, and telephone theft notification.
Turing now to the method for collecting statistical information about cellular public phone use and performance metrics, each of the phones in the network is configured with an internal non-removable primary SIM card. This primary SIM allows the network operator to interact directly with the phone enabling the phone to collect data about itself and then transmit that data to the network server. Therefore, the processing unit installed in each telephone may be configured to collect operational data regarding the telephone. This operational data may be, but is not limited to, phone usage, and performance metrics such as operational functionality of the physical elements of the telephone, the operating system and the cellular network. The operational functionality of the physical elements of the telephone may include, but is not limited to, the handset, the LCD display, the key pad, service door status (open or closed), the power supply and battery level. The operational functionality of the cellular network may include, but is not limited to, network interruptions and downtime.
The operational data is periodically uploaded to the network server as per a preset schedule thereby providing a database that can be analyzed to provide valuable information relating to a single telephone, a particular group of telephones or the entire cellular phone network. Further, each telephone may be programmed such that specific data will generate an immediate notification to the system operator via an "Alert". The data that generates an "Alert" may be, but is not limited to,
malfunctioning or non-functioning handset, LCD display or power supply, and the service door opening. Such malfunction or non-function may be indicative of a broken or stolen part. It will be appreciated that such alerts may be cancelled by the phone once the cause for the alert has ended. By non-limiting example, an alert may be generated when the telephone door is opened and the alert may be cancelled when the door is closed. However, a record of the alert and the alert and the cancellation of the alert are recorded by the management system operator via the system computer.
The periodic uploading of data may be at predetermined times or on demand. Further, the uploading period may be changed by communication with the phone by the system operator over the network or by a technician working directly on the phone.
Regarding the method for management of a large number of cellular public telephones, the present invention provides a computerized management system that is configured to analyze data collected from the individual fixed cellular telephones as described above. The data may be manipulated to provide the service provider with valuable information regarding the operational status of each individual phone in the network, a specific group of phones, or the network itself.
As mentioned above, each telephone may be programmed such that specific data will generate an immediate notification to the system operator via an "Alert". Such an "Alert" may result in the substantially immediate generation of an "Alert" pop-up window on a computer that is monitoring the operation of the network. The pop-up window may display the nature of the problem and the location of the phone. This will enable the service provider to respond in a timely manner to the needs of
the phone, whether it is by means of a technician physically going to the phone or, if possible, downloading software via the cellular network.
Individual phone information may include, but is not limited to, incoming and outgoing airtime and number of calls for each, incoming and outgoing SMS traffic, by number and airtime, network interruptions, network downtime and the quality of the power supply, either AC, DC battery or both. The same information may also be analyzed for a specific group of phones or the entire cellular network. The specific group may represent a single network cell or a group of cells that service a particular geographical area of interest such as a town or village. It will be appreciated that the management system may be used to display information on a "real time" basis, for a time range such as day, week, month or year, or for a specified time range such as between two specific dates, or time of the day. The data may be displayed using substantially any suitable display format such as, but not limited to, charts, graphs and tables. It will be understood that the management system of the present invention is also configured to assemble the data into a "report" format. Reports may include, but are not limited to, system information, usage statistics, and maintenance handling.
A side benefit of fixed cellular telephones is monitoring of network stability. The data collected by each phone in the system regarding network interruptions and downtime may be used to determine problems within a particular network cell such as, but not limited to, equipment problems and tower placement. Based on the number of interruptions, the duration of each interruption and/or the total duration of power interruption to an individual telephone or a group of telephones, problems
relating to the electric power grid in an area may also be assessed. The data relating to such power interruptions may be based, by non-limiting example, on the amount of time backup battery power is used to power an individual telephone or a group of telephones. Such data may be uploaded to the network server in the form of an alert, or as part of a routine data transfer.
It will be appreciated that the above information is in addition to information regarding individual users based on collecting data relevant to each individual phone number in the network corresponding to each secondary SIM card configured to work within the network. Since the physical telephone is owned by the service provider, the service provider may make changes in the operational functionality of the phone via the primary SIM card. Therefore, system upgrades and or patches may be downloaded to the phones by the system operator. The downloads may be to a single specific phone, a group of phones or all of the phones in the cellular network. The service provider may also program each of the phones via the primary
SIM to either block or allow specific IMSI numbers and/or ranges of numbers. The instructions to block or allow the IMSI numbers and/or ranges of numbers may be downloaded to a single specific phone, a group of phones or all of the phones in the cellular network. Further, the blocking or allowing of IMSI numbers and/or ranges of numbers may be with regard to incoming calls only, outgoing calls only or both incoming and outgoing calls.
An IMSI range of numbers may be based on any one, or combination, of the mobile country code (MCC), the Mobile Network Code (MNC) and /or the Mobile Subscriber Identity Number (MSIN).
Alternatively, a range of numbers may be based on the MSISDN number, which is the number actually dialed when placing a call. A non-limiting example would be allowing calls to all phone numbers having an 800 prefix, or blocking all calls to all numbers having a 900 prefix, for example.
It should be noted that using a combination of IMSI and MSISDN numbers to define a range of numbers is also within the scope of the present invention. It should be noted that since the infrastructure of the cellular public telephone network of the present invention is compatible with mobile cellular phone technology as well, therefore the inclusion of private mobile phones within the cellular phone network of the present invention is within the scope of the present invention. Turning to the feature of telephone theft notification, as illustrated in Figure 1, one benefit of fixed cellular telephones relates to theft notification. Due to the fixed nature of the telephones, each of the phones in the network is usually registered in a particular cell or number of cells. When a phone registers in a different cell, the management system may be configured to generate a theft alert. The service provider will also be provided with a list of cells within the network in which the stolen cellular telephone is subsequently registered so as to be able to track the stolen phone to the point of being able to identify at least the geographic area of the cell or cells in which the phone is currently registered.
As schematically illustrated here, a cellular telephone network may include cells 4, 6, 8, 10 and 12 with cellular public telephone 2 is in a stationary fixed deployment at location 2a so as to register within cells 4, 6 and 8. If cellular public telephone 2 is moved to location 2b so as to register in only cell 12, the management system described above will interpret the change as the theft of cellular public telephone 2 and generate a theft "Alert". The general area covered by cell 12 may also be given to the proper authorities to aid in recovering the stolen cellular telephone.
Finally, regarding the feature of a four-button telephone operation interface, the cellular telephone of the present invention is configured such that substantially all of the operational features of the phone such as, but not limited to, scrolling through the feature menu, opening a feature such as the phonebook, scrolling through the phonebook, opening the incoming or outgoing calls or messages, scrolling through incoming or outgoing calls or messages, choosing an entry in any one of the lists and placing a call or sending a message to that entry, may all be accomplished by the use of only four keys, an "Up Arrow" key (f ), a "Down Arrow" key (J,), an "OK" key (OK), and a "Back Arrow" key (<-).
To this end, the cellular telephone of the present invention is configured with an "Up Arrow" key (|), a "Down Arrow" key (|), an "OK" key (OK), and a "Back Arrow" key (<— ) in addition to an alphanumeric keypad on which keys '2-9' are used to enter numerals or letters. The '0' key is the alpha "space" key. The T key is used to enter symbols such as, but not limited to, '.', '?', '-', ':', 7' and '.'.The '#' key is used to switch between uppercase letters, lower case letters and numerals. The '*'
key is used to enter either '*' or '+'. When the cellular telephone of the present invention is in data entry mode, the "Back Arrow" key (<■— ) is used to erase the last character and the "Up Arrow" key (|), and "Down Arrow" key Q) are used to scroll within the text. Configured in this manner, once a user's secondary SIM card is registered on the network, the user can select a telephone number from the phonebook and place a call to that number solely through the use of the four operation buttons, the "Up Arrow" key (t), the "Down Arrow" key (|), the "OK" key (OK), and the "Back Arrow" key (•<— ) by the following steps. 1. Press the "Up Arrow" key (|), or the "Down Arrow" key (J,) to scroll through the options (Phonebook Options, Short Message Options and PIN Options). When "Phonebook Options" is displayed press the "OK" key.
2. Press the "Up Arrow" key (|), or the "Down Arrow" key (!) to scroll through the options (View Phonebook, Search phonebook, Add New
Entry). When "View Phonebook" is displayed press the "OK" key.
