Description

METHOOD FOR TRANSMITTING VOICE OR DATA IN A WIRELESS NETWORK DEPENDING ON BILLING ACCOUNT STATUS}

The creation and development of billing systems in general and dynamic real-time debit systems has been the main goal of terrestrial and wireless communications since the early days of the telecommunications industry. However, most conventional dynamic charging systems do not yield efficient and safe systems. Most cellular and personal communication system (PCS) communication networks use billing systems that are not "dynamic" or "real-time", and have cumulative or cumulative talk time built from 15 to 30 days of revolving billing procedures and accounting policies. time) depend on usage history These procedures are generally unsatisfactory and result in many usage fraud and negligence accounts. The consequences of cellular fraud and negligence accounts require cellular and PCS network management to meet stronger customer approval policies. In many urban markets, cellular and PCS fraud and malpractice accounts are so prevalent that new applicants with sufficient credit will have to pay a deposit in the range of $ 300 to $ 1,000.00 only to open the service. Due to such protection, about 70% of potential cellular and PCS users are rejected because their credits are not the best and they cannot afford the required deposit.

It is therefore a primary object of the present invention to provide a unique, secure and efficient real time cellular and PCS debit “cash debit” debit system. The present invention relates to interim standards or "IS" standard documents and European telephone system (ETS) documents known in the art, such as cellular IS-553 AMPS, TACS, IS-54B and IS-136 TDMA, IS-95 CDMA dual mode cellular. Such a wireless communication system described and known in the art; And Mobile Communications Globalization System (GSM), DCT-1800, DCT-1900, Personal Digital Cellular (PDC), European Digital Cordless Telecommunication Standard (DECT), Personal Handy Phone System (PHS), Cordless Telephone System (CTS), Ardis Other systems such as data, RAM data, and all other wireless data and voice communication standards; It works seamlessly and squarely with all known cellular and personal communication systems (PCS). The invention also utilizes a unidirectional broadcast paging system, physical and logically defined analog and digital control channels, satellite system control and access channels, digital access channels, and CDMA IS-95 access channel data burst fields. Indeed, the present invention provides a debit methodology based on combining control, digital access channels, and digital control channels, and creates unique control channel application data (CCAD). CCAD combines paging, DCCH, SS7, and other system protocols that support voice and data cellular. Additionally, the present invention provides a digital control channel (DCCH) messaging service provided by Ericsson Switching Company, in the TDMA IS-136 version, and the equivalent CDMA IS-95 DCCH provided by Qualcomm Corporation of San Diego, California. Take full advantage of the messaging system.

The present invention truly creates a new "debitphone" technology. Most conventional debit phones cost almost $ 1,000.00 each. These phones typically have a credit or debit card slot through which the user can push the card, and the phone sends all the information to the host serving cellular network. After confirmation, the user can make a phone call.

The present invention provides a simple but orderly alternative to this cumbersome, expensive and very insecure methodology. One serious problem with conventional debit systems is that credit card information and other critical user specific information is transmitted and thus susceptible to cellular hacker scanning devices. Hackers can easily capture this critical information and use it for illegal purposes.

The debit phone of the present invention does not cost more to manufacture than other conventional cellular, PCS or cordless phones. The invention also operates within conventional IS-41B and IS-41C signal network guidelines and is in fact transparent to the host cellular network. IS-41 is a set of standards that use the Signal System Seven (SS7) 56 kbps broadband network full duplex protocol used throughout the cellular and PCS industries for inter-MSC communications. The SS7 network also supports many other signal based activities and is used for the method of the present invention. No infrastructure or other equipment needs to be added to any host cellular or PCS network. The present invention creates a Master Central Monitoring Station (MCMS) which is a Point of Presence or Service Control Point (SCP) on the SS7 network. The debit communicator of the present invention is always considered to be a "roamer". Currently, there are two main roamer networks: North American Roamer Network (NACN) and ITE or GTE Mobile Link networks. The IS-41 SS7 network is not like the Internet for switches and is now ubiquitous throughout the United States. Another 64 kbps SS7 network is used throughout Europe and Asia. The invention preferably is " added " to cellular and PCS networks, in particular at the mobile switching center (MSC) and requires only about 1 hour of system programming time. Programming simply involves updating the call handling, routing the parameter table, and creating a new layer of debit services. This programming does not include update switch operating system software, or any other aspect that may include software "patches" and revisions. These switch software patches or revisions are usually operated by the original switch manufacturer. These control channel application data debit (CCAD-DEBIT) systems disclosed herein are a marked advance over all prior art cellular and PCS debit systems.

The invention also creates a debit bank center (DBC). This DBC is connected on a public switched telephone network (PSTN) in much the same way as an automatic deposit payment processing (ATM) system. However, the main difference between conventional ATM access and the present invention is that the MCMS is constantly communicating with the DBC through a carefully encrypted protocol. This dynamic approach is necessary to retrieve even small changes in the CCAD-DEBIT phone system user debit account. Any changes or updates can be constantly compared to MCMS debit user records, and the CCAD debit phone timer is sent whenever a debit user attempts to access the currently available serving cellular or PCS system for voice and short data packet services. Register data. The MCMS and DBC also operate on the Internet and the World Wide Web (WWW) through frame relay and other signaling methods. Thus, the present invention will enable easy access to cellular and data services to those who have not been able to easily access these services so far. In addition, the present invention eliminates the high cost, potential fraud problems and risks from cellular and PCS networks. The present invention will relieve cellular and PCS carrier responsibilities from having to significantly increase cellular and PCS use by the public and maintain heavy accounting policies. With the present invention, the CCAD-DEBIT user merely goes to the bank or any ATM and electronically pays the funds through the ATM or credit card. If a potential user wants to purchase a CCAD-DEBIT phone from a bank, electronics store, or cellular provider, they only pay for the phone and the seller has a 10-digit CCAD identification number (CIN) and a 10-digit mobile identification number (MIN). Allocate CCAD-DEBIT phone users do not have to pay for the service or sign any contract. For example, if a CCAD-DEBIT user wants to pay a batch total, for example, pay $ 500.00, and talk time is 40 cents per minute for voice and 15 cents per transaction for CCAD-data, or some other fee. When there is a schedule, the user can periodically check the DBC to see how much time he has spent. The only other feature is that MCMS sends a notification to the user telling the user how much credit is left in the user's account. This reminder is sent over alpha-paging or DCCH. Cellular or PCS carriers benefit from CCAD-DEBIT user business, share revenues with CCAD-DEBIT system providers, but give up billing issues for CCAD-DEBIT system providers and DBC debit phone user cellular or PCS voice and data Responsible for billing. One major drawback of conventional cellular and PCS charging systems in use today is the rounding of use per minute. For example, if a user uses a talk time of 1 minute 30 seconds of cellular or PCS, he pays for 2 minutes. The preferred CCAD-DEBIT system is incremental, so the CCAD-DEBIT phone user pays only for exactly what he uses. If the user uses a talk time of 1 minute and 30 seconds, he pays for everything proportional to that, 1 minute and 30 seconds. Another important aspect of the present invention is to directly enhance cellular and PCS network control functions and signaling routines and to fully support and enhance voice services. The present invention also enhances and extends cellular and PCS network control, accounting and fraud detection procedures. The unique debit phone firmware and software combination of the present invention creates a very secure communication system. CCAD-DEBIT phones are built with physical and logical change protection.

The CCAD-DEBIT system utilizes an overlay debit system that is added to existing cellular, PCS and mobile satellite system physically and logically defined control channels and digital access channels without the need to add any hardware or software to those systems. The present invention utilizes the Visitor Location Register (VLR) and Home Location Register (HLR), which are standard SS7 and IS-41 Service Control Points (SCPs), on the SS7 network. These databases interact directly with the mobile switching center (MSC) for the purpose of maintaining cellular, PCS and mobile satellite customer data files, Romer profiles and other related user data. The present invention utilizes HLR and VLR in a unique and efficient manner, but within standard operational guidelines. The present invention utilizes such standard cellular, PCS and mobile satellite system access procedures such as voluntary registration, initiation, remote function access control, CDMA and TDMA digital access data bursts, and other similar procedures for transmitting unique debit protocols.

(Summary of invention)

Accordingly, an object of the present invention is to provide a control channel application data debit (CCAD) as a means and methodology for creating an orderly, simple, secure and cost-effective cellular, paging network PCS and mobile satellite based voice and data packet service pre-payment debit system. -DEBIT) to provide a system. It is another object of the present invention to operate as cellular, PCS and mobile satellite physical and logical control channels, digital access channels, digital traffic channels, digital signal channels, reverse analog control channels, reverse digital traffic channels, digital access channels, short messaging media. TDMA IS-136 and CDMA IS-95 forward and reverse digital control channels (DCCH), and debit systems for use on SS7 and X.25 signal protocols. It is yet another object of the present invention to provide a master central monitoring station (MCMS) which is configured as a standard SS7 IS-41 compatible service control point (SCP). The present invention also provides a debit bank system (DBC) application specific facility. DBC is a facilitator / bearer that interacts with MCMS on the PSTN. MCMS interacts with the serving MSC on the SS7 network. For example, when a user is moving in a particular serving cellular, PCS, or mobile satellite system that is a system serving a particular geographic service area (GSA), metropolitan service area (MSA), or rural area subscriber area (RSA), The only but transparent procedure takes place. For example, in one scenario, a CCAD-DEBIT phone user specifies a cellular service on a cellular store that interacts with a bank ATM or directly interacts with a bank providing the debit cellular voice and data packet service of the present invention. Paid in advance. Once a service credit is purchased by a debit phone user, the debit amount is automatically sent from the DBC to the MCMS and recorded in the time zone. A debit phone user enters a phone number via the debit phone keypad and presses the send button to make a short-range call from a mobile phone to a land phone. This "call request" is actually a control channel or digital access channel initiation procedure. For example, a debit phone user makes this call in the US AMPS analog cellular system in New York. The debit phone is configured to operate in dual mode with digital CDMA and analog AMPS. The control channel protocol used in AMPS analog cellular is based on the 800 mHz frequency 10 kbps 30 khz wideband frequency division multiplex (FDM), 48-bit word BCH hamming coded protocol. In a typical initiating access procedure for the AMPS cellular standard, about three to eight 48-bit control channel words may be transmitted at any given time. Conventional electronic serial number (ESN), mobile phone identification number (MIN) and other mobile phone control channel related data are typically included in these 48 bit words. ESN and MIN are used by all cellular, PCS and mobile satellite phones. However, debit phones also use CCAD serial numbers (CSN) and CCAD identification numbers (CIN) for separate data and one-way voice only. CSN and CIN are also used to make one-way voice calls and receive pages. This particular debit phone is also configured as a two-way pager and the unit includes a fully integrated pager receiver. The CSN also acts as a pager receiver cap code. The cap code is typically broadcast over a given paging network, but only one pager is programmed to detect messages containing the cap code. The disclosed debit phone, configured as a combined voice and data unit, interacts only with the paging and cellular network. This paging unit is fully integrated into the phone, and its microcircuits and operating software fully interact with the cellular transceiver included in the phone. Indeed, a pager mounted CCAD-DEBIT phone may receive coded commands from the MCMS to the phone via the PSTN and Paging Network Control Center (PNCC). Various unique control and command commands may be sent to the debit phone through a paging network that allows the phone to perform various functions that are known but may not be known to debit phone users. Another important aspect of CCAD-DEBIT phones is the inclusion of non-volatile memory-based flash registers / timers. A timing increment represented by a number of hours, minutes, and seconds is a register with a simple but very efficient function that yields four digits. This timing register is very important for CCAD-DEBIT phones and is a physically embedded register module included in the phone integrated circuit. Any unauthorized attempt to change, remove, or reprogram will result in self destruction of the register module RM. Destruction of this register module will also disable the CCAD-DEBIT phone. The register module also keeps a record of all data packet transactions including received pages and transmitted CCAD data packets. In addition, other absolute security and anti-fraud procedures operate on MCMS and DBC to ensure user debit account security and continuity.

When a debit phone user makes a voice call, the debit phone sends its CIN and CSN, four digit voice talk time register number, and / or data packet count, dialed number and other related control channel, or digital access channel initiation data. do. When a debit phone user purchases a specified amount of credit, "credit" data is sent from the DBC to the MCMS data terminal via the PSTN immediately after the user purchases the call and data credit. The transmitted control channel initiation packet is received by the nearest serving cellular system base station and then relayed to the connected serving MSC. The MSC reads the dialed number, ESN and CSN where a particular routine procedure occurs. The MSC recognizes that the 34 bit 10 digit CIN is 176-777-1234 and its eight character 32 bit CSN and the phone is a CCAD-DEBIT phone. The MSC also reads all dialed numbers. However, the CCAD-DEBIT phone also contains a register / timer four digit number contained in the dialed numeric field. This four-digit timer number is not entered by the debit phone user, but is automatically obtained and placed in the selected dialed numeric field. Accordingly, the present invention provides for dialing manually entered by a user, such as when a user dials any seven or ten digit directory number to make a call from a mobile phone to a land phone or from a mobile phone to a mobile phone. It handles data fields and presence data that are typically designed to contain only numbers that are counted. The MSC analyzes these numbers along with other numbers, but what is included in the CCAD-DEBIT phone initiation control channel data packet is a special sequence of dialed numbers that cause the switch to initiate a remote function access control procedure. This important procedure is described in standard IS-41-3B; It is part 3.8 to 4.2, allowing various types of remote functions to be started from the remote home location register (HLR). The CCAD-DEBIT phone preferably always has a roamer state so that any serving cellular system receiving the will always be relayed to the MCMS which will be almost always located at a remote location away from the serving MSC. When the serving MSC detects the debit phone CSN and CIN, it recognizes that this unit belongs to another serving system located far from another city, state or province. The CIN is identified as belonging to a CCAD-MCMS that includes data service and processing service control points (SCPs) that send and receive data to and from MSCs such as standard HLR. To start a CCAD-DEBIT phone voice and two-way data service, the cellular or PCS network simply loads its CIN and CSN parameter table values into the MSC and the service is started and so simple. No other equipment or operating system software upgrades are necessary. CIN, CSN, dialed numbers and other data are converted to IS-41 / SS7 Mobile Application Part (MAP) protocol and sent to MCMS. By combining standard dialed numbers with four digit register / timer numbers, the present invention provides application specific data; That is, it looks like standard control channel and digital access channel numeric data, but in reality it produces encrypted and processed data that creates only application-specific debit and bidirectional paging data. This register / timer data is application specific data "shown" as standard dialed numeric data by the serving MSC, but in practice it is not. Debit phone users do not have direct control over these application specific debit data, they are automatically obtained, processed and sent along with other procedure initiation data. Since the register / timer debit data is transmitted to the CCAD MCMS HLR / SCP over the SS7 network along with other conventional initiation control channel and digital access channel data, the MCMS receives this debit packet and reads all the data. Through CSN, and CIN analysis, MCMS identifies the packet as a CCAD application specific debit packet belonging to a specific debit phone user. The register / timer is started when the debit phone user makes a call or sends a data transaction. If it is a voice serving request, the serving MSC assigns a reverse voice channel to the debit phone user. If it is a simple data message, the reverse voice channel is not assigned and the message is relayed because it is contained in the control channel initiation packet. When the called subscriber answers the call, the timer records the accumulated talk time of each call. The timer then stops when the debit phone user ends the call by pressing the end button. If it is a simple data message, the transaction is counted. Each time a debit phone user makes a call and is approved by the CCAD MCMS and the serving cellular system MSC, the register / timer starts and records the call duration until terminated by the CCAD-DEBIT phone user. When numbers are analyzed and compared in MCMS, if the debit account is new, this is the first time the user has requested a service, and then the register / timer numbers must all be set to zero "00:00". If the account is old, then the register / timer number received is compared to the assigned debit limit supplied by the DBC. If the debit phone user has not reached his credit limit, then the call is accepted and the MCMS sends an acknowledgment back to the serving MSC via the SS7 network using standard IS-41 SS7 Mobile Application Part (MAP) protocol guidelines. . If the debitphone user has used up all his pre-payment credits, then MCMS sends a cancellation response to the serving MSC and the call is blocked. When the debit phone user is blocked, the phone software causes a notification that says "All credits used" to be displayed on the LCD display. The user then knows to have to go to a bank or cellular phone vendor who can also access the bank debit record and purchase more talk time and / or data time. When a debit phone user purchases more talk time from a bank and immediately attempts to make a call, a debit phone initiation-application specific packet is sent to MCMS in the manner mentioned so far. The MCMS data management terminal compares the number of registers / timers received with the last time the user accessed the system. Each time a debit phone user attempts to access the CCAD-DEBIT system, the access record is time stamped, the register / timer number is recorded with the unit CSN and CIN and electrically filed to the debit phone usage and startup records. Time stamping ensures that all records are kept in a hierarchical relationship with when they arrived, compared to when a user purchased a new talk time and data packet limit, and newly received register / timer time stamp data was updated. Ensures that it can be compared with register / timer time stamp data. Conversely, bank debit account status can be accurately compared with current MCMS and received register / timer data. In this way, all records are kept accurate, and debit phone users are properly treated and minimization of fraud and other possible abuses, even if not actually eliminated. Another important function of the present invention is to use the forward analog control channel FOCC and the forward digital traffic channel to transmit the CIN. The present invention uses a CIN in much the same way that cellular, PCS, and satellite systems call or page a user when a call is made from a landline to a mobile phone or from a mobile phone to a mobile phone. CCAD-DEBIT is designed not to receive voice calls and can only receive messages from a page from a unidirectional paging network or from a serving cellular network TDMA-DCCH or CDMA-DCCH type forward messaging channel. In this way, the debit-phone is not issued a MIN number and has a programmed CCAD identification number that looks like a ten-digit phone number but is not actually. CIN is used for one purpose with the debit phone and allows the register / timer built into the CCAD-DEBIT phone to return to zero. For greater security, the debit phone also receives encrypted command messages from the MCMS via a unidirectional paging network or a serving cellular carrier CDMA-DCCH or TDMA-DCCH forward messaging path concurrently with CIN transmission. Debit Phone User When a debit account is updated with a new voice and data time purchase entered into the DBC, and immediately recorded and time stamped in CCAD-MCMS, the encrypted code and transmitted CIN return the debit phone register / timer to zero. Let's do it.

Another important feature of the present invention is its bidirectional data debit based messaging and bidirectional paging functionality. For example, application specific messaging beyond four digit register / timer data may be sent with the CCAD-DEBIT control channel initiation packet. In one configuration, the CCAD-DEBIT phone is programmed to send some "canned" data message response. For example, a CCAD-DEBIT phone user may receive a page from a one-way paging network, a serving cellular system TDMA-DCCH, or a CDMA-DCCH forward messaging path, and a debit phone user may send up to 15 messages. A message, for example message 6, says "I'll call you in 10 minutes." All the user has to do is press the menu button, select the bidirectional paging function, then select the message 6, press the set button, and then press the send button. The debit phone transmits a normal CCAD control channel or digital access channel initiation packet. However, in addition to the timer register / timer numbers, instead of including dialed numbers for voice calls, the CCAD initiation packet contains the pager caller's seven or ten digit phone number. The CCAD control channel initiation packet includes a data packet transaction counter field calculated by the data packet counter register software that also drives the register / timer module. This data packet counter is calculated in the same structure as a register / timer used for the accumulated voice use talk time measurement. When a CCAD debit phone bidirectional paging message is preferably sent, only the data packet usage number is included in the same register / timer field. Once the CCAD control channel initiation packet is processed by the MSC and relayed to the CCAD MCMS via the SS7 network, the MCMS data management database is operational. MCMS verifies the user and returns the appropriate acknowledgment to the serving MSC. This response prevents the switch from stocking or grabbing the forward voice channel and completing the bidirectional paging data "call" by sending a forced release order to CCAD-DEBIT via an overhead signal occurring on the FOCC channel or forward digital traffic channel. do. Thus, the present invention creates a two-way paging system, and a user is charged a flat fee for a two-way paging packet transaction. The CCAD debit phone user may or may not pay for the interactive paging service, which is an optional additional service for the CCAD voice service.

Remote function access control is a standard IS-41 feature that allows a mobile phone user to manually enter a call routing command into the home HLR when an HLR is received that causes all mobile or landline calls to be routed to another destination. The message also waits for an indicator or is sent back to the user over the SS7 network to the current serving system and then relayed to the mobile phone user over the forward channel. The present invention uses the remote access function control parameter only uniquely because it is an application specific data message medium in the disclosed methodology. The remote access application message (RAAM) function looks like a normal initiated remote function access control packet that is part of the means and methodology of the present invention. In this way, the invention creates processed data in the control channel and digital access channel, but actually creates processed data in the SS7 signal network, where the CCAD-DEBIT RAAM packet "looks" like a normal remote access function control data packet. Because.

In yet another scenario, the present invention creates a truly new, yet another short messaging system in its scope that actually creates a surprisingly robust and orderly efficient application specific, signaling network and air-interface protocol driven short packet data messaging system. It provides a means and methodology for doing so.

In order to achieve the above object, in accordance with the purpose of the invention as embodied and broadly described herein, a completely comprehensive cellular, PCS, globalization system and mobile satellite voice and data service application specific control channel application data debit system (CCAD-DEBIT) Provided are a specialized data communication protocol and communication device that provides a. The system uses existing data and data fields to produce processed data and creates application specific debit data. This debit data is transmitted on a physically and logically defined control channel. The control channel is an analog FSK specified in an official document generally selected as a set of standards by the Telephone Industry Association (TIA), the Interim Standards (IS) issued by the American Standards Institute (ANCI), and the European Telephone Standards Commission (ETS), Signal channels using digital TDMA, digital CDMA, quadrature shift key control channel protocols and other wireless analog and digital network platforms, digital traffic channels including logically defined digital access channels, digital signal channels, primary digital Widely defined here, such as an access channel, a secondary digital access channel, a fast associated control channel, a slow associated control channel, an authentication channel.

Additional objects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, and may be taught by practice of the invention. The objects and advantages of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims.

The present invention will now be described in greater detail in order to represent preferred embodiments of the invention illustrated in the accompanying drawings. In describing preferred embodiments and applications of the present invention, specific terminology is employed for the sake of clarity. However, the invention is not intended to be limited to the specific terminology so selected, and it is to be understood that each particular element includes all technical equivalents that operate in a similar manner to accomplish a similar purpose.

Referring to Figure 1, the CCAD-DEBIT communicator receives a message from the MCMS over the selected air-interface downlink (219). The communicator is shown as debit phone 100 in FIG. 2. In terms of the present invention, the downlink includes a message sent over a unidirectional paging network; Or a message sent over a DCCH path of a host cellular network configured for forward messaging specified in temporary standard 136; Or a message sent over a DCCH path of a host cellular network configured for forward messaging specified in the interim standard IS-95; Or a message transmitted over the forward data path of the mobile satellite downlink; Or a message sent over the forward analog control channel FOCC as specified in the interim standard IS-553; Or as a message transmitted via a forward DCCH message from a mobile communication globalization system (GSM) signal and / or an authentication channel. The debit phone then reads the data contained in the received downlink message (275), evaluates and responds to the received downlink message (276), or stops responding if the message does not require a response at the same time (277). . If the debit phone does not need to respond, it initiates a return response (278). The debit phone scans and detects the forward downlink network channel of the host serving cellular, PCS, GSM or mobile satellite system (279). Next, the debit phone handshaking with the forward network channel (280). Preferably, the debit phone is then assigned to the channel in synchronization and ready to transmit an initiating data burst (281). Debit phone initiation preferably includes a request 282 for voice service and includes a CIN / CSN for registration grant and call routing 283. The initiation packet also includes a register / timer field 284 with, for example, 20 minutes of remaining talk time. Or the debit phone requests data service (285), the debit phone simultaneously transmits registration and authentication information in the initiation packet (286), and transmits the CIN / CSN in the initiation packet (287). The base site receives and detects the service request included in the debit phone service request (288) and relays the debit phone service request to the serving MSC (289). The serving MSC analyzes 290 the initiation request by scanning and detecting the CIN / CSN and the Remote Access Application Message (RAAM) indicator included in the dialed numeric field. The serving MSC relays 291 initiated / registered and included dialed numeric field data to the MCMS. The MCMS analyzes the launch / registration request (292). The MCMS verifies or rejects the request (293) by sending a service approval or denial of service indicator to the serving MSC via the SS7 network (294). If the MCMS approves the voice service, the MSC and Visitor Location Register (VLR) assign a temporary suto number to the debit phone user and assign a reverse voice channel (295). Or if this is a data service request, send a data service acknowledgment / completion of the call indicator to the serving MSC, and at the same time send a soil number cancellation call indicator to the VLR, and the MCMS routes the packet to its application specific destination. The application specific destination may be a two-way paging response center or other facilitator. After receiving the request, the MCMS preferably sends an account update to the Debit Bank Center (DBC) (297). The DBC responds immediately and sends the debit phone user account update information (298). The MCMS receives the update (299), timestamps the update (300), and then adds new debit account information (301). The account debit limit is the same as in the previous query (302), or the account limit is increased (303). In this scenario, the debit phone user is simultaneously sent a register / timer update account packet in both directions. Firstly, the CIN is sent to the debit phone user via the MCMS to the serving system MSC, whereby the MSC sends the debit phone user CIN to the debit phone via the FOCC or forward digital access, paging or traffic panel. The CIN is then received. The second encrypted message is transmitted via the designated downlink path, preferably via the transmission medium mentioned so far. When the debit phone receives an encrypted register / timer reset call, the register / timer is set to zero.

2, this exemplary diagram illustrates the CCAD-DEBIT system. Preferred CCAD-DEBIT system air interface and network elements are shown. CCAD-DEBIT phone 100 transmits a control channel application data packet (CCAD) 103. This data packet contains a CCAD Initiation-Remote Application Message (RAAM) activator, a CCAD Debit Register / Timer-Four character data fields, and other related initiation data. The CCAD data packet 103 is sent to the nearest serving cellular or PCS base site 101, or mobile satellite, in this example Inmarsat P mobile satellite 114.

In FIG. 3, the air interface protocol represented in this embodiment is based on the AMPS IS-553 analog RECC control channel standard 107 and the CDMA IS-95 digital access channel standard 102. In FIG. The CCAD-DEBIT phone 100 is preferably configured as a D-AMPS or dual mode AMPS phone compatible with AMPS analog and IS-95 CDMA digital air interface protocol standards. If a dual mode debit phone user is moving to a serving cellular system that is only compatible with the AMPS analog standard, then the CCAD-AMPS protocol 107 is used. This data packet consists of seven 48-bit analog RECC control words. If a dual mode debit phone user is moving to the serving area of an IS-95 CDMA compatible system, CDMA packet 102 is used.

In Figure 4, the CCAD-AMPS application specific data packet 107 is shown divided into seven separate 48-bit RECC words. The IS-553 AMPS RECC reverse control channel protocol described here will allow up to eight 48-bit words to be transmitted in one burst. This particular example is based on a standard start data packet, but actually includes data specifically configured for the CCAD-DEBIT system. For example, A-word 125 includes a station class mark (SCM) "1011" 137 indicating that this phone is a debit phone. The CCAD identification number CIN consists of a three digit office code 261 and a four digit node code 128. In the B word 126, the three digit plan region (NPA) or the region code 133 of the CIN is here. Shown. Together, these ten number codes contain CIN. This number looks like a normal ten-digit directory number. A person dialing this number from another mobile or landline phone cannot reach a debit phone user with a CIN number. CIN and CSN are used for debit phone identification by serving MSC and CCAD MCMS. As mentioned so far, the CIN is also used for debitphone register / timer security and control, combined with another encrypted data code that is sent to the debitphone via another downlink path, thus combining two key encryption methods together. Create. CCAD serial number (CSN) 136 in word C 127 represents the CCAD-DEBIT phone serial number. CIN and CSN are used together for registration, initiation and all unit identification for MSC, SS7 network and CCAD MCMS data analysis and processing procedures. D word 131 is a standard configured start packet; The first word of the called address is used to transmit a dialed number entered by a typical mobile telephone user. However, with the present invention, the D word is one application specific H word; Or H [1] word 131. For purposes of CCAD debit phone registration, the H [1] word 131 is sent to the MCMS along with the A, B, and C words. The H [1] word may include other application specific data that has not been manually entered by the user. In fact, all CCAD H words are preferably obtained automatically via CCAD debit phone firmware and software means. CCAD debit phones do not have direct control over what is included in the CCAD H word data field. All data in this H [1] example 131 is automatically obtained with embedded software and hardware. For example, the E word or the second word of the called address is represented 132 as the H [2] word by the debit phone system. In this word, a bidirectional paging response-callback number 122 is represented. Typically this word contains a number that is trunked directly to the PSTN and called by the serving MSC, instead this number is a pager or pager queuer that pages the debit phone user. This number is also sent to the CCAD MCMS, for example along with the message number (6) 118. As soon as received, the pager currant number is preferably fed to a specialized voicemail system using the number that called the subscriber, and the subscriber picks up the phone and, for example, "I'm sorry but I can't talk now, so I'll call later tonight. I will do it "(6). The third and fourth words of the called address are also represented by the present invention as H [3] word 123 and H [4] word 124, respectively. Each includes application specific data 141, 142, 143 and 160 including information related to global positioning satellite information and other position triangulation data. These data fields can be used for all manner of additional debit system security and service related applications. These analog H words and the full AMPS IS-553 based protocols represented herein are one of the analog and digital control channel and digital access channel protocols that can be used by the present invention for the purpose of implementing CCAD debit systems in the cellular, PCS and mobile satellite industries. It is just an example.

Referring now to FIG. 2, man-machine-interface (MMI) 116 is preferably a Unix-based computer terminal used by cellular network signal and switch experts to enter new data into a parameter table data file. These mobile phone identification number (MIN) data files are used by the MSC to identify the system to which the various MIN numbers belong. The present invention uses these files in the same way, however, the CCAD debit phone CIN is IS-41 / SS7 specific global, allowing MSC software to know where to direct debit phone packets to MCMS on a special SS7 network such as NACN. Used only to append cluster and node code. As soon as the MSC identifies the MCMS's HLR 162 as a true point-of-presence on the SS7 network, it relays the entire CCAD debit phone application specific launch / registration packet to the MCMS 106. As soon as a particular CCAD debit phone initiation / registration packet arrives, the following procedure preferably takes place as shown in FIG. The received CCAD-DEBIT phone packet arrives and is converted from the SS7 / IS-41 packet to the CCAD HLR read data format (237). Within this readout are the register / timer numbers 139 and CCAD-DEBIT phone CIN 260 that make up part of the debit phone user active profile. Within this profile are the type of service and call number initiated by the debit phone user, such as voice and data indicator 251. Additional information contained in this string is a register / timer cumulative time indicator 139. When the packet arrives, it is time and date stamped immediately (129).

In FIG. 5, normal IS-41 and SS7 requests specify that an operating SS7 Service Control Point (SCP) such as HLR should be redundant. CCAD-MCMS is preferably represented as HLR / SCP, so both HLRs must be provided and have to be online. If one HLR fails, then the other takes over immediately. Thus, the CCAD MCMS has two HLRs, one co-located in the MCMS (162) and one remotely located in another physical location (171). The remote HLR 171 can be placed in another city or region as long as it is located on the same power grid as the co-location HLR 162, so that a local power failure will not cause a failure of both HLRs. Terminal 168 includes a data algorithm that continuously retrieves debit phone packet 237. When the DEC terminal 168 detects the debit phone packet 237, it captures the packet, relays it to the comparison database (CDB) terminal 169, investigates the user's current debit limit, and most recently received the debit phone packet. It compares with the reception information contained in 237. If there is enough debit credit remaining and the logically received register / timer matches the last register / timer data received, start the registration and current call acknowledgment, forward it to CCAD HLR 162 and 171, and CCAD The HLR relays it to the serving MSC 104 via the SS7 network. The serving MSC allows for voice calls. If the debit phone user is requesting permission to send a two-way paging packet, the same procedure applies. 4, if the debit phone user's debit account has residual credit for talk time and data packet transactions, the two paging queue numbers 122, the message indicator 118 essentially flag the MCMS and the decoder terminal This instructs it to be a data packet transfer request and not a request for a voice service. If the H [2] word 132 does not include the message number indicator 118, it indicates that it has read "0", and the decoding terminal then makes the packet as a voice service request initiation / registration voice service request packet (VSRP). Flag it.

Referring to FIG. 5, in yet another scenario, the debit phone packet register / timer data counter field 129 indicates to the comparison database (CDB) 169 that all credits have been used, with the service block indicator then CCAD. It is relayed to the serving MSC via the HLR. However, CDB 169 constantly updates debit account information by constantly asking Debit Bank Center (DBC) 120. The CDB 169 preferably queries the DBC through the data reception and distribution (DRD) terminal 167. DRD controls the direct link data frame relay link to the DBC. The DBC may be a cellular, PCS or mobile satellite system. Or, alternatively, it may be a conventional bank providing cellular, PCS, and mobile satellite debit services.

2 and 5, an automatic deposit payment (ATM) system of bank 154 may be essentially coupled to DBC 120. Debit phone users can purchase talk time and data packet credits simply by going to any ATM or bank configured to provide voice and data debit services. Dealer 252 that records debit phone user cellular purchase information may be configured to interact directly with the MCMS and act as a debit user database.

In FIG. 5, merchant 252 may also have access to user credit card and ATM accounts. There are many ways to configure these functions. In essence, under any circumstances, MCMS is constantly asking the Debit Bank Center (DBC) 120 to receive new debit user account information updates for the purpose of providing trouble free service and to prevent abuse and fraud. Ongoing comparisons of the most recently received date, time stamp and register / timer information with previously received information ensures a secure and efficient CCAD debit phone system with continuous DBS questions. In addition, there are other important functions of the CCAD-DEBIT phone system.

6, six different versions of the downlink protocol are represented. Paging Network Protocol 147, TDMA DCCH IS-136 Protocol 148, CDMA DCCH IS-95 Protocol 149, Mobile Satellite Protocol 150, Analog AMPS IS-553 FOCC Protocol 151, and Mobile Communications Globalization System Digital Access Channel-Authenticated Channel Protocol 152. Each protocol serves its own function and is correlated with other expressed protocols. This correlation includes support and accumulation of delivery of alpha-numeric messages to debit phone users, fraud-preventing, and debit account management. For example, some of these messages are provided for two paging services, and other messages are related to debit limit notification. Another important feature is the two key encryption and anti-fraud parameters that are designed for the CCAD debit phone system. For example, if a debit phone is configured to operate in an IS-553 AMPS cellular system and a one-way paging broadcast system, the following communication procedure applies. 5 and 6, one possible scenario is for a debit phone user to purchase another block of voice service time and data packet transactions. His last access attempt indicates that he has accumulated 21 minutes 32 seconds of voice service talk time. However, a recent DBC 120 question indicated that he had purchased another two hours of voice time and 30 additional data or two paging transactions. Compared to previously received start / registration data and time-date-stamping, and register / timer data, the time stamp applied to the most recently obtained DBC record indicates that the user has updated his debit account. Thus, this particular debit phone user voice time and data transaction register / timer count must be reset. The preferred reset procedure is as follows. Suppose this current debit phone is configured for one-way paging and analog AMPS services; The MCMS 106 sends a debit phone user CIN number 260 to the serving MSC 104, which sends the page through all connected base stations 101. This page contains the CIN number 260 of the debit phone user. Debit receives this number. At the same time, another encrypted message is sent to this same debit phone through the serving paging network. 2, MCMS 106 sends a message queue to paging network control center (PNCC) 221, where the CCAD debit phone is encrypted code 108 as represented in FIG.

In FIG. 2, the PNCC 221 sends a message to the nearest paging network transmission tower located in the serving system geographic service area (GSA). As soon as the debit phone receives the encrypted code message, the registers / timers are all set to zero. The encrypted code message 108 is combined with the CIN 260 to create two key encryption systems for use with the CCAD debit phone system. In yet another example, the debit phone is configured as a code division multiple access (CDMA) IS-95 compatible full duplex voice and data communication device.

Referring now to FIG. 3, CDMA access channel protocol 102 includes various potential application specific elements. The access channel capsule 222 includes an access channel message 223. Within this message is a variable message length body 226. The message body 226 allows up to 210 characters or two 842 bits of data to be sent in one burst. The message structure preferably includes a bit indication 227 that ensures robust application specific data burst protocol. The message length field 265 tells the base site and the MSC what message length it is. For example, if the message length is 110 bits, the 8 bit message length field will reflect that number. The padding function 224 of the CDMA access channel message creates a "bit filler" mechanism. In view of the CDMA access channel protocol procedure, the access channel capsule never changes in length. Internally, however, the padding function "fills" empty data bit fields within the message body. For example, if the message is equal to 110 bits but the bit field calls for an additional 732 bits, the padding field occupies an empty data field with binary zeros. Periodic redundancy ratio 225 ensures data bit integrity by constantly checking the amount of data content and other factors. The CDMA digital access channel structure operates essentially in the same way as the AMPS RECC analog reverse control channel shown in FIG.

The debitphone initiation / registration methodology of the present invention applied to the CDMA-RAAM procedure version of the present invention operates with the MSC call parameter table, and the host IS-41 / SS7 network in the same manner as described so far. The only real difference between the AMPS-IS 553 Debit Phone procedure and the CDMA-IS-95 Debit Phone procedure is how the phone itself is configured to operate within the guidelines of these two different air-interface protocols. MSC and MCMS voice call handling and data packet handling are managed in essentially the same way as described so far. By way of example in FIG. 3, the initiation / registration packet 107 having four H words 235 and also identified as the called address word 117 is managed in the same manner as in the CDMA digital access channel protocol 102. .

In FIG. 6, debit phone 100 is configured to operate in a CDMA-IS-95 environment as a whole. In FIG. 5, CDB 169 begins to send a downlink message to a debit phone user. The CDB prepares a message for the DCCH message center 263 and sends it across the PSTN 110 via the T1 / DSO protocol 105, which protocol is used routinely on the PSTN 110. DCCH message center 263 receives the message and relays it to serving MSC 104 via PSTN 110. The CCAD debit phone receives the downlink message on the CDMA IS-95 DCCH forward digital control channel downlink 151. This message may include a page from the caller using the phone 113 on the PSTN, an encrypted message, or an alpha message indicating to the debit phone user that his debit limit has been reached. Both paging responses are included in the initiation / registration packet that the CDMA debit phone compiles and sends, and the data is processed by the serving MSC in the same manner as described so far. Thus, the CCAD CDMA IS-95 compatible debit phone provides a self contained full duplex voice and data debit system. In FIG. 6, TDMA IS-136 downlink message 148 may be used. Indeed, if the CCAD debit phone is configured to operate entirely in a TDMA IS-136 environment, or in a GSM environment, a CDMA environment, or a mobile satellite environment, the MCMS and data management procedures will not change. The key is how each debit phone is organized. For example, the CCAD debit phone may be designed to receive a broadcast page 147, transmit an initiation / registration data packet on a GSM digital access channel, and make a voice call on a GSM digital traffic channel. The RAAM function works the same. Indeed, the RAAM function can operate on all known cellular, GSM-PCS, CDMA IS-95, and TDMA IS-136 network platforms as long as these platforms are compatible with IS-41 / SS7 signal network parameters. All known cellular, PCS and GSM platforms to date operate with remote function access control parameters fully utilized by the RAAM procedure of the present invention. All platforms mentioned so far will also accept specialized CINs and CSNs, and in fact CINs can be sent and transmitted on forward page procedures in the same procedural manner.

As shown in FIG. 2, MCMS 106 may transmit a message to a dual satellite and cellular compatible debit phone. The debit can receive messages from mobile satellites, such as the Inmarsat P satellite 114 represented herein, as long as the phone is so configured. The MCMS 106 simply transmits the message over the SS7 network 115 or the PSTN network 110, the satellite system network center ground station or hub 109 transmits the uplink message, and the satellite transmits the CCAD debit phone 100 ) Relays and sends messages.

The present invention provides a unique means and method for implementing a " caller pay " terrestrial phone to mobile phone call methodology to a CCAD debit phone. In FIG. 2, the caller makes a call using a “900” number 153 using a landline telephone 113. Calls from the 900 number landline to the mobile are routed to the MCMS 106. The MCMS queries the CCAD HLRs 162 and 171 to find out which serving cellular or PCS or mobile satellite system the debit phone user is operating on. Whenever an MSC sends an Initiate / Registration Call request to any HLR that includes a CCAD HLR, the MSC is essentially responsible for which serving cellular system is sending a message, in particular which MSC is sending Initiation / Registration call requests. The carrier identification code (CHIC) to be identified is transmitted. Each time the MSC sends an Initiate / Registration Call Request, the CIC code is sent in the same IS-41 / SS7 packet. Thus the CIC code is identified with the serving system location represented by the MSC 104.

Referring now to FIG. 5, serving MSC 104 is connected to a visitor location register (VLR) 249. The VLR is also a database that is a Service Control Point (SCP) on the IS-41 / SS7 network. In fact, VLR works almost exactly like HLR. The VLR keeps a record of all roaming mobile phone users who are actively operating in that particular serving system for a 24-hour period. Each roaming mobile phone is assigned a landslide number. This number is used to be represented as an active Romer if any call is received at the MSC. When a roaming mobile phone registers for the first time in a serving MSC operation area, the home cellular or PCS system HLR is interrogated in the same way as described so far. If the mobile roamer electronic serial number (ESN) and mobile phone identification number (MIN) are sent to the home system HLR, and the roamer's data file is present on the HLR and his account is in sufficient state, then the HLR is with the roamer profile. Send a registration grant message to the serving MSC. The serving MSC downloads the successful registration result and the Romer profile and assigns a soil number. The VLR duplicates the roamer profile and the assigned soil number and sends it to the home HLR via the IS-41 / SS7 network. Thus, the current location of all active registered users is always maintained. Referring to Figure 5, when a "900" number from a land phone to a mobile phone is dialed by the terrestrial PSTN caller 113, the call is routed through the MCMS automatic voice / mail-PBX system 253 to the MCMS HLR 162; 171). The caller is told a pre-recorded voice, for example, "Enter Your Personal Identification Number (PIN) 174". The caller enters a PIN number, and the PBX system 253 checks its file and asks a comparison database (CDB) 169 which compares the received PIN number with all stored debit phone user PIN numbers. After the PIN number is confirmed to be valid, the CDB 169 sends a PIN verification call, and in addition sends a debit phone user CIN and CSN number to the PBX system 253 which in turn questions the CCAD HLR 162, 171, Check for the most recent location and soil number assignments. Once the soil number is pinpointed, the HLR sends the soil number and the most recent serving MSC CIC number to the PBX system 253 and essentially routes the call to the serving MSC 104 VLR 249.

In Figure 2, serving MSC 104 pages the debit phone user by sending its CIN number through an analog FOCC forward control channel, or a base station using a digital access forward primary or secondary paging channel. After being contacted, the debit phone user presses the send button and the call begins. In the mentioned application, the caller preferably pays only when the debit phone user answers the call, so that no talk time fee is absorbed by the 900 or 800 number fee. After the call is terminated by the terrestrial caller 113 or the debit phone user, the caller no longer bears the 900 or 800 number charge. Debitphone register / timer status was not performed by a call from this land phone to the mobile phone. If no PIN is entered or if the terrestrial caller is not using the 900 or 800 number service, no other call is made to the debit phone user. No one accidentally dials a CIN number to reach a debit phone user. CIN is used only for identification, routing, and 900 number call forwarding, which is essentially the method used here by the present invention but in the only way.

7, a preferred embodiment of the CCAD debit phone 100 is shown. The debit phone has a speaker 158, a microphone 159, and a liquid crystal display (LCD) screen 156, a menu key 175, and a setting button 176. Keypad 164 is preferably used only for dialing a landline telephone number or another mobile telephone number. Press the Menu key to scroll through and search for any or "canned" messages for the debit phone bidirectional paging response function. After the desired bidirectional paging response is located in the menu selection displayed on the LCD screen 156, press the set button 176, and then press the transmit button 177. This procedure causes the initiation / registration packet to be sent in the manner described so far.

Those skilled in the art will readily recognize additional objects and advantages. The application of the methodology and apparatus is wide and can be used in a truly wide range of wireless communications. Thus, in a broader sense, the invention is not limited to the specific descriptions, representative devices, and embodiments shown and described.
