Description

Method for Two-way Communication and Processing of Control Channel Application Specific Data

BACKGROUND OF THE INVENTION

1. Field Of Invention

The present invention relates to wireless data communications networks such as cellular, paging, and satellite networks that can support two-way paging and other two-way messaging services. In particular, the present invention relates to two-way communications methods and protocols for cellular mobile radio systems, paging communications systems, and satellite network systems.

Description of Related Art

A variety of methods and apparatuses have been proposed for two-way data communication. Cellular and paging concerns have offered various approaches for two-way paging and two-way messaging. Heretofore, however, all such methods and apparatus have proved to be inefficient, cumbersome, and expensive. For example, one prior method has required the use to speak into a pager, store the voice, send the voice message, and then it is received by the recipient. Another approach has been to utilize cellular wireless operations broadly known as Personal Communications Systems (PCS) , Global System for Mobile (GSM) , and Enhanced Specialized Mobile Radio (ESMR) .

Such prior methods and systems offer various forms of what is generally termed value added bearer services, two-way point-to-point short messaging, broadcast messages, voice mail, single number services, broadcast information services, electronic mail, and the like. Such services, however, utilize expensive and inefficient voice or traffic channels. Other services proposed include motor vehicle fleet management, motor vehicle anti-theft, and topographical coordinate systems that provide location data to bearer services processing centers, also known as central monitoring stations. Such service are provided by sending data packets over conventional voice traffic channels in a point-to-point manner that uses a significant amount of cellular network processing and user load bearing capacity. Circuit switching of such data packets is inefficient, unreliable, and expensive.

Other systems such as Cellular Data Packet Data (CDPD) operate on existing analog and digital voice traffic channels. CDPD is very expensive to use and operate over a cellular network. Moreover, CDPD utilizes a very complex protocol and end use equipment is very expensive. Also CDPD is not designed to handle short messaging as it is primarily configured for transmitting and receiving large data files from computer to computer. As such, heretofore there has been no practical, low cost, means or method for wireless two-way paging and two way data messaging.

Two-way paging and two-way short messaging communications do not require large data file transfer, and sending short messages on cellular traffic over voice channels is very expensive and cumbersome. Therefore, the present invention provides both the means and methodology of creating a two way paging and short messaging system that creates an additional function to cellular system access and control procedures that is simple, efficient, and cost effective. The present invention provides a precise and controlled application data packet methodology that logically creates a separate but compatible continuous control application data protocol (CCAD) to existing cellular access protocols, thereby creating an elegant application data routine which becomes a normal part of cellular system data management and mobile station management. At the same time the present methodology adds a much needed cost effective, highly flexible, and elegantly simple two way paging solution that is easy- to-use, profitable to the cellular carrier, and affordable and practical for the consumer. Additionally, the present invention creates a virtual communications system by merging two distinctly different communication mediums that are currently in use today namely, cellular control channels, and one way broadcast paging

SUMMARY OF THE INVENTION

Accordingly, it is the primary object of the present invention, to provide both the means and methodology for establishing a completely new communications system, with the expressed purpose of creating a new virtual two way short messaging communications network, that combines the data communications protocols of existing cellular network control channels and existing one way broadcast paging networks. Such existing cellular mobile radio networks include for example, American Mobile Phone System (AMPS) , Total Access Communications System (TACS) , personal communications systems (PCS) and Global System for Mobile (GSM) networks. It is another object of the present invention to provide specialized data protocols that operates seamlessly without having to significantly modify existing network cellular and paging network infrastructure. Furthermore, the present invention dramatically reduces the direct cost of implementing a wide spectrum of control channel application data CCAD two way short messaging that up until now forced wireless network operators to spend millions of dollars to implement inefficient and costly data packet systems that support very limited and expensive two way data communications systems. The present invention provides a pristine and elegantly simple solution for implementing efficient, flexible, and low cost two way data short messaging communications that include, but are not limited to, synchronized, asynchronous, packet switched, packet assembler/dissembler access protocols that make possible a virtual application specific messaging two way data system that allows for efficient and low cost applications such as two way paging, certified paging, smart paging, location paging, fleet management, anti- fraud protection, home arrest, keep-aways, medical alert, personal protection 991, remote sensor monitoring, utility meter reading, and provides an efficient communications pathway for Global Positioning System (GPS) data management, dead reckoning, Loran C data communications, and other location data management services.

It is another object of the invention to provide data protocols that seamlessly fit within the existing access, signaling and control channel protocols used for cellular and paging networks without causing disruption to existing, cellular, and paging network voice traffic, data traffic operations, or other control channel routines. Furthermore, the present invention does not significantly impact any host cellular and paging system capacity. In fact the present invention in no way causes any switching and network capacity problems, it is essentially a stand- alone virtual control channel application data communications network that does not need to utilize any part of the cellular switch. However, the present invention can be adapted and fully integrated with all cellular base transceiver stations (BTS) , base site controllers (BSC) and mobile switching center (MSC) switching, and processing schemes, with simple switch operations software patches that allow for recognition, processing and routing of control channel application data (CCAD) data packets. These software patches maximize system efficiency while at the time minimizing any impact upon overall cellular system capacity. The present invention adds application specific data words in three broadly defined ways. First, by tagging application specific data, onto cellular system access and signaling protocols, that are contained within multi-word data packets that transport user information contained within registration protocols, origination protocols, equipment registration protocols, home location register (HLR) access protocols, visitor location register (VLR) access protocols and the like, (other applicable signaling protocols may be found in documents such as interim standard 41, that describe SS7 network functions and procedures, as endorsed by the Telephone Industry Association (TIA) ) . Secondly, by creating a distinct logical channel protocol that is transportable over existing analog and digital physical access channels used by all cellular standards in the world today. Thirdly, by creating separate and distinct data protocols that are compatible with existing control channel protocols, and therefore create a still different approach to system management by adding new service related functions to system access and other management schemes. These physical and logical channel protocols are preferably transmitted from CCAD communications terminals to cellular system base stations, mobile switching centers (MSC) and subsequently relayed and routed to the public switch telephone networks (PSTN) and public land mobile networks (PLMN) . These data words are created and transmitted by the present inventions core application specific communicators and terminals for the purpose of sending two way messaging responses either in a pre¬ determined form or by utilizing a terminal keypad to send highly variable and individual text multi¬ character responses. Other data that can be sent include global positioning system (GPS) correlative reference data bits, dead reckoning, and Loran C data and other terminal, and/or application specific device status bits to master central monitoring stations (MCMS) , that process and relay the data words to individual system facilitators and end users. The present invention offers unique interface protocols that are programmed to provide a transparent integration of these device status bits, with physical and logical control channel and access channel bit fields that are normally used by analog and digital cellular terminals for host cellular system access, registration, origination, frequency assignment and other related physical and logical control channel and access channel processes. The present invention's application specific status bit fields are preferably sent simultaneously with standard physical and logical control channel and access channel information bits, and are virtually transparent to the host cellular system. Furthermore, the present invention provides for a separate and unique continuous channel application data channel (CCADCH) protocols that in fact create additional and distinct logical protocols for all known analog and digital cellular access channels.

Accordingly it is a further object of the present invention, to provide both the means and method for reading and processing such special application specific data words at a cellular system base transceiver station (BTS) , base site controllers (BSC) and mobile switching centers (MSC) without taxing host cellular air-interface system and switch resource capacity. Such special application specific data words are received, scanned, recognized, recorded at the base transceiver station (BTS) , base site controller (BSC) and mobile switching center (MSC) , and then routed to master central monitoring facilities, paging network control centers, and service bearer centers for direct interaction with a variety of end user application specific apparatuses via the PSTN, paging, and other networks.

The present invention also provides for full duplex communications by integrating cellular transceivers, and paging receivers that communicate together within specially designed end user CCAD communications terminals. The instructional or command messages are preferably sent from the Master Central Monitoring Station (MCMS) by electronic and man-machine interface terminals via the PSTN/PLMN networks, to designated paging network controllers, and paging transmission towers. In turn these instructional and command messages are subsequently transmitted to one or many CCAD communications terminals. Once the CCAD communications terminal receives the special command, instructional or human syntax displayed alpha numeric message, it is programmed to automatically respond by processing and recognizing the significance of a particular command message received from the paging network, or visually instructs the user via a liquid crystal display LCD screen to perform some function. The response is then transmitted over the physical and logical control channels and the signaling and access channels of host cellular network, in the heretofore mentioned manner.

To achieve the foregoing object, and in accordance with the purposes of the invention as embodied and broadly described herein, specialized data communications protocols and communications apparatuses are provided allowing for specialized application specific data communications for use with cellular mobile radio networks, personal communication systems (PCS) network, global system for mobile (GSM) and satellite system networks. The methodology is integrated in and operates within existing physical and logical control channel, signaling channel, digital traffic channel, primary digital access channel, sub digital control channel, secondary digital access channel, fast associated control channel, authentication channels, slow associated control channel, and all other control channel protocols that utilize analog FSK, digital TDMA, digital CDMA, and other wireless analog and digital network platforms.

A preferred method comprises the steps of: transmitting application specific messaging bits utilizing control channels containing data related to an application specific system. Transmitting the messaging bits over digital and analog control channels utilizing AMP, D-AMPS and TACS FSK modulated reverse control channel RECC 10 Kbps 48 word BCH hammering coded control channel means. Preferably the application specific messaging bits being transmitted through a communicator means configured as an integrated paging network receiver and a cellular control channel application specific transmitter. Applying the messaging bits to communicate with, identify, monitor, and locate the application specific system, allowing for an integrated application specific two-way communications system. The application specific system may comprise a two-way paging system, a motor vehicle location status system, a motor personal location status system, a home arrest status system, a security system, a utility meter reading status system, and the like.

Another important feature of the present invention is its ability to provide accurate message accounting, in that each CCAD data packet is considered an individual transaction, therefore the bearer facilitator is charged for only the CCAD two way data packet sent, not a blanket cellular per minute charge. 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, or may be learned by practice of the invention. The object and advantages of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended c1aims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

Reference will now be made in detail to the present preferred embodiments of the invention as illustrated in the accompanying drawings. In describing the 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 understood that each specific element includes all technical equivalents which operate in a similar manner to accomplish a similar purpose.

In accordance with the present invention there is provided a method for transmitting application specific messages over cellular radio system control channels, comprising the steps of: transmitting application specific messaging bits utilizing control channels containing data related to an application specific system. Transmitting the messaging bits over digital and analog control channels utilizing AMP, D-AMPS and TACS FSK modulated reverse control channel RECC 10 Kbps 48 word BCH hammering coded control channel means. Preferably the application specific messaging bits being transmitted through a communicator means configured as an integrated paging network receiver and a cellular control channel application specific transmitter. Applying the messaging bits to communicate with, identify, monitor, and locate the application specific system, thereby allowing for an integrated application specific two-way communications system. The application specific system may comprise a two-way paging system, a motor vehicle location status system, a motor personal location status system, a home arrest status system, a security system, a utility meter reading status system, and the like.

In accordance with the present invention there is also provided a method for converting data within an control channel application specific communicator configured as a integrated paging network receiver and cellular network control channel application specific transmitter, comprising the steps of: receiving data commands and instructions from a paging network; processing the data commands and instructions; and transmitting automatically application specific data status messages over AMPS, D-AMPS and TACS FSK modulated reverse control channel RECC 48 bit BCH hammering coded control channel means utilizing compatible control channel protocols, allowing for an integrated application specific two-way communications system utilizing existing cellular radio networks and paging networks, thereby creating a control channel application data virtual communications system.

Referring to FIG. IA, a flow chart of a preferred methodology is illustrated when a CCAD communicator responds 221 or does not respond 222 to a received message from paging network. The CCAD communicator preferably does not communicate to the CCAD virtual network if there is no reason in terms of differentiation of communicator internal system status. If the CCAD communicator needs to respond 223 to paging network message, it then creates a record, scans the cellular carriers forward analog control channel or forward digital control channel carrier radio wave 224, handshakes with forward channel carrier wave 225, digital or analog, and then synchronizes with the analog or digital air interface protocol 226. Once synchronization is complete, the CCAD communicator bursts its analog or digital data packet 230. Then the Continuous Control Application Data Channel (CCADCH) base site transceiver (BTS) system scans all data packets 231, and subsequently detects data packet 232. Once detected, the CCAD base transceiver site system processes packet 233, by converting it to a public switched telephone network protocol, preferably Tl/El, and routes the packet to the mobile switching center (MSC) 234. The MSC then processes the packet by counting each packet 235, and then routes the packet via the PSTN to the master central monitoring station (MCMS) 236. Once the packet is processed, the MCMS routes the data packet to the bearer facility 237. The bearer facility evaluates the status of the bits contained within the packet, and chooses not to respond 238, or to respond 239, by sending a command request to the MCMS 240 via the PSTN Tl or dial in direct (DID) via normal telephone lines. The MCMS then receives, accepts and verifies the command request 241. The MCMS subsequently creates command data packet 242, and subsequently sends command data packet to the CCAD communicator 243 via paging network 244, and/or via satellite network 245, and/or via forward analog control channel FOCC 246, and/or via forward digital control channel FDCCH 247, and/or via cell site broad cast channel BCCH 248. This aforementioned protocol method operates in this preferred manner with all cellular air interface and network standards.

Referring to FIG. IB, a CCAD virtual network preferably comprises an CCAD mobile communications terminal 100, a plurality of base transceiver sites (BTS) 101, and base site controllers (BSC) 224. A plurality of mobile switching centers (MSC) 104 communicatively linked with to a CCAD data word packet discriminator/processor 115, which is preferably located at each base transceiver site (BTS) 101 and at each mobile switching center (MSC) 116. A public switched telephone network (PSTN) 110, Tl carrier 105, a landline telephone 113 for public access, a master central monitoring station (MCMS) 106 regional processing center, and a plurality of application specific facilitator bearer service providers (FAC) 120. A plurality of global positioning Navstar satellites (GPS) 112 and Inmarsat P satellites 114 are preferably operably linked with cell broadcast transmitters 226, specialized control and access channel receivers 227, paging network controllers (PNCC) 221, and satellite system network controllers 109.

Preferably each base transceiver site (BTS) 101 and base site controller (BSC) 224 is physically positioned, and electronically integrated with one another, or alternatively, represent base transceiver 15 sites (BTS) 101 that operate as a separate system that is physically spaced from the BSC 224. Both systems are integral parts of any cellular mobile radio network, and utilized to implement the present invention, regardless what standard and cellular operations platform the present invention is adapted to. The CCAD system may be configured with the following cellular operations standards; AMPS cellular, TACS cellular, ETACS cellular, NMT cellular, TDMA cellular, CDMA cellular, and/or a Global System for Mobile (GSM) cellular network systems. The present invention operates in the same protocol and network methodology regardless what air-interface protocols and modulation formats a particular cellular systems control channels, access channels and overhead signaling channels are configured for, be it digital or analog. Furthermore, the base transceiver sites (BTS) , base site controller (BSC) , mobile switching centers (MSC) , the PSTN and Tl/El spans are, preferably, part of an existing cellular communications system which operates over a designated cellular communications band.

The MCMS 106 and FAC 120 which are CCADCH virtual network system installations, comprising for example, one or more computer terminals for processing data word packets, sending command instructions to the correctional facilitator, and monitored subject, and for maintaining system performance and account records. The MCMS and FAC also contain standard telephone lines, GPS, Loran C, dead reckoning and other topography tracking software, and readout displays, multiplexing switches, PSTN lines, Tl/El lines, and other standard central monitoring and service center equipment, widely known in the art. As will be explained in more detail below the, BTS, BSC, MCMS and FAC preferably process all received CCAD data word packets and configure all command and instruction data words to be transmitted to the end-user by operating software programs contained within the processors and terminals located at these CCAD system installations.

Each CCADCH multi-word FSK RECC analog packet 103, transmitted from an CCAD communicator 100, contains location GPS bits, and other pertinent application specific status bits. This particular packet is designed to operate within the parameters of the American Mobile Phone Standard (AMPS) and Total Access Communications System (TACS) cellular system control channel and network protocol processing routines. Additionally, as seen in FIG. 2, the preferred methodology for creating the CCAD data packet, transmitted the CCAD data packet, and recognizing, scanning, detecting, routing and processing the CCAD at the BTS, MSC, PSTN, MCMS and bearer/ facilitator centers is illustrated.

Referring to now to FIG. 2, a CCAD data packet 103 utilizes a 48 bit word designated as an H word; Hi through H4 235, each word is made up of 36 information bits and 12 parity bits, and is specifically designed to contain and carry application specific data bits such as GPS correlation location position bits and other mentioned CCAD status bit information. This particular AMPS and TACS RECC protocol allows for up to eight words to be sent in one RECC multi-word data packet or data burst. The creation, transmission and management process of data packet 103 is as follows. Most CCAD applications will typically require no more that two H words to be transmitted along with the other three CCAD communicator identification, and service information words, however certain CCAD applications will require only one H word to be used, and others will require up to five H words. Still other situations require a second burst or packet of data to be sent. An additional string of eight words can be sent, as a separate but related packet 248, whereby the CCADCH data system for AMPS and TACS becomes a two burst or two packet protocol. This second packet contains an identification word 250 that indicates to the base transceiver station that it belongs to a particular subjects CCAD communicator whom just transmitted the first packet 103. There are many uses for this additional packet. For example, sending alpha character messages to a paging network center that interfaces directly with paging customers, and persons sending alpha or numeric pages to a CCAD two way messaging communicator that can be entered by attaching a personal digital assistant (PDA) to the CCAD communicator.

In FIG. 9. CCAD communicator 100 as communicator paging apparatus 275, is connected to a small personal digital assistant (PDA) keypad 252. The connection is physically made by a special port 253 located on the side of the communicator 275. The keypad is used for sending two way paging responses and other messages that require more characters to be transmitted. Referring to FIGS. 2 and 9, the first burst 107 and second burst 249, enables the communicator 275 user to send up to 72 characters to the person who initially paged him. Using the PDA keypad 252, the user can send personalized messages to whom ever pages him, and he does not have to just be limited to "canned" or embedded responses. However, the communicator user can transmit canned responses that are embedded in the communicator software, and accessed by the user via a menu display, if response time is a factor. Another important feature is, instead of utilizing traffic channels and specialized modems, these messages are sent via control channels with CCAD communicators without the need of specialized modems, creating a direct protocol-to-protocol data link. This keeps end user equipment cost very low, typically no more than a normal cellular phone, and provides a simple and efficient communications methodology. Additionally, some digital access and control protocols allow for up 184 CCADCH data bits, and an unlimited application specific data packets to be attached to registration packets, origination number packets, and other signaling packets. In still other cellular radio digital systems, application data packets can be sent independent of all other access protocol routines, are as stand-alone CCADCH packets, as long as a designated cellular control channel and access channel operations standards allows for separate and independent application specific data word packets to be transmitted, received, recognized and processed. But, for purposes of explanation and disclosure the FSK RECC 48 bit multi-word packet will be detailed further.

FIG. 3 is a block diagram of an FSK RECC 48 bit autonomous CCAD data packet with one H word attached, and depicts the three words of the preferred CCAD packet, and illustrates an example of the significance of each information bit. This FSK RECC 48 bit data packet is in fact a separate and distinct continuous control application data channel CCAD air interface protocol that is a modified yet compatible AMPS, D-AMPS and TACS control channel protocol. This CCAD protocol operates like a registration protocol, but in fact can be transmitted and accepted by the base transceiver station (BTS) and the base site controller (BSC) mobile switching center (MSC) as a distinct protocol specifically designated to be utilized by systems and application specific bearer services for the purpose of enabling a wide variety of application specific services.

In FIGS. 1 and 2 CCAD communications terminal 100 is preferably configured to operate within the parameters of AMPS, NAMPS, DAMPS, TACS and ETACS cellular standards. The CCAD communications terminal 100 preferably transmits a CCAD data packet 103 that is configured as an CCAD data packet. The CCAD packet is received by the BTS 101, via an individual sector antenna 122, which is directly attached to a control channel sector receiver 227, that converts air interface protocol to RS232 electrical protocol. The BSC 224 contains a special processor 115 that scans all control channel or access channel data packets and detects all CCAD data packets. The present invention provides for a separate sector receiver 227 that is attached in tandem along with a standard control channel BTS receiver. Furthermore, this stand alone receiver 227 is directly attached to a separate and distinct CCAD data packet discriminator processor 115 that operates completely independent from the BSC processor 224. In this way the methodology of the present invention can operate and act independently from normal control channel data processing routines. However, the present invention can operate seamlessly without the need to add separate BTS and BSC hardware and software. Standard BSC software can be modified to recognize and process CCAD data packets by simply utilizing a software patch to existing BSC processor registers to detect and route CCAD data packets to the MSC 104 via Tl/DSO pathways 105 that are provided by the PSTN 110, that will enable the host cellular network to utilize the present inventions means and methodology without having to add one bit of BSC and BTS hardware. Furthermore, the MSC 104 switch software can be programmed to receive and recognize CCAD data packets and automatically route said packets to the MCMS 106 via Tl/DSO routinely used by the PSTN 110. In fact the entire CCAD data messaging system can be implemented and integrated with any cellular network and its operations standard with software patch modifications to any and all BTS, BSC and MSC's without any need of adding separate hardware. However, certain cellular network operators may choose to implement CCAD technology without the necessity of modifying BSC, BTS and MSC operations software, yet still wanting the benefits of the technology. Therefore the present invention provides a CCAD network overlay system, that in fact creates a separate and distinct CCAD virtual network that operates in tandem but transparently to the host cellular network. Essentially, the present inventions separate hardware and software virtual network approach operates exactly the same way as a CCAD BSC, BTS and MSC software only modification solution, the only difference to the software only solution is the addition of radio receivers, separate time division (TDM) multiplexers, and routers at the BTS, BSC and MSC's. In reference to FIG. 2, the CCADCH data packet 103 is preferably transmitted from CCAD communications terminal 100 and sector antenna A 122 receives the data packet. Special CCAD sector receiver one 227 receives the CCAD data packet 103 along with all other control channel and access channel data. The sector receiver one converts the air interface modulated protocol that contains the CCAD data packet 103 to RS 232 data protocol and routes the data packet to the CCAD BSC multiplexer 117, the multiplexer receives the data packet and routes the packet to the CCAD main BSC processor. The processor scans and detects only CCAD control channel and access channel data and ignores all other non CCAD data packets. In fact, the processor passively scans and detects CCAD data packets without causing disruption to any and all other control channel and access channel operations. Additionally, the cellular network is configured with the CCAD hardware and software virtual system and ignores the H word and only recognizes the first three words of this data packet. This data packet closely resembles an autonomous registration packet, but may be used for separate and distinct applications as described. The H word is only relevant if the BSC, BTS and MSC is software patched and configured to recognize the H word or any other CCAD data words. Otherwise the CCAD hardware and software virtual system operates totally separate from the host cellular network. Once the CCAD data packet is scanned and detected, it is then routed to the D4 channel bank 121 and a designated D4 channel bank card 118. The D4 channel bank card converts processor protocol into Tl/DSO protocol 105 and routes the CCAD data packet via the PSTN 110 to the MSC 104, whereby the CCAD MSC processor receives the data packet, processes it and routes it to the MCMS 106 via the PSTN 110 for processing. If the second CCAD packet 249 is requested, the first packet contains second burst request bits contained in one its H words, sent by the end user. The I.D. word 249 of the second packet instructs the base transceiver site CCAD processor to attach this second packet to the first packet and thereby process the entire two burst string as one total transaction.

As further shown in FIG. 2 multiplexer 117 may accommodate up to three separate sector receivers. For example, depicted here are three CCAD communicator communications terminals 100 that transmit three separate CCAD data packets and the multiplexer receives each one, at slightly different time increments. Depending upon which of the three packets arrives at the multi-plexer from the three sectors antennas and receivers, it is then sent to the processor 115 on a first come first serve basis. The second packet 249 is processed in the same manner. The multi-plexer is synchronized to the cellular control channel access channel synchronization clock to maintain timing accuracy. Sector antennas (a) 122, (b) 123, and (c)

124, can fully load the sector receivers (a) 227, (b) 228 and (c) 229, with data packets and the CCAD multiplexer will process all incoming data packets at full network traffic load without loss of system efficiency or cause for breakdown.

As further shown in FIG. 3, the CCAD multi-word data packet in the form of FSK RECC AMPS and TACS protocol is an analog protocol that is configured as a logically arranged bit pattern that operates on a frequency assigned designated physical control channel, in the same way as fully digital protocols do with TDMA and CDMA cellular access protocol systems. The A-word 125 contains 36 information bits, however for CCAD data packet purposes the only bit fields pertinent are the mobile identification number (MIN) 128, the number of additional words coming (NAWC) field 129, and the station class mark (SCM) 130 bit fields. The MIN number is the ten digit directory number assigned to all mobile terminals. All mobile terminals, including CCAD communications terminals are assigned an MIN number. The MIN number uniquely identifies the CCAD communications terminal as belonging to a paying cellular system user, assigned to a specific cellular carrier that operates in designated geographic area. The primary MIN number is made up of seven digits, as depicted in the A word 125. CCAD communications terminals also have normal cellular terminal voice capabilities like all other cellular communicators. The B-word 126, contains the three digit area code 133 of the full MIN number. Additional information contained in the B-word is the order qualifier code 134 and the order code 135. These two code fields instruct the BSC to perform various tasks. This particular order code "01101" tells the BSC that this data packet that appears as an autonomous registration RECC string that in fact is an CCAD logical channel protocol, therefore no voice or traffic channel service is requested. Once CCAD is operated standards may be assigned for the CCAD so that its own order code does not cause any voice or traffic channel to be assigned. Since the RECC FSK protocol allows up to eight words in one data packet, utilizing five words for CCAD RECC data packets packet is completely acceptable, and does not any way circumvent current RECC analog control channel protocol standards. The A-word 124, contains an NAWC 129 field. This field instructs the BSC to expect a designated number of words to be counted and received in this particular data packet. The A-word 125 NAWC field 129 instructs the BSC to expect four additional words to follow the first word received. In fact, each word indicates in its own NAWC field to expect so many additional word to follow. In this way adding two or more H-words to an CCAD data packet, thus transforming it into an CCAD data packet is entirely acceptable to standard operating protocol. There are four principal RECC control channel message categories; the page response message, the origination message, the order confirmation message and the order message. The page response message is initiated by the MSC and base site. For example when a mobile station is called it is essentially paged from the serving cellular system as a result of a land-to-mobile or mobile-to-land call or message. An origination message is a type of order message initiated by the mobile station when voice service is requested by the mobile user. The particular order code and order qualifier contained within a standard origination message cause the mobile switching center to authenticate the user, and assign a voice channel. Dialed digits are contained in the D, E, F, and G words and are sent along with the A, B, and C words that are used for registration purposes, and also cause the switch to route the call to a particular land based switch, or to another mobile station within its own service area, or to another mobile switching center in another serving area. 25

In FIG 3, the A, B, and C words are used in the CCAD data packet in the same manner as the origination message, however, the order code 134 and order qualifier code 135 contained in the B word essentially instruct the mobile switching center to "read" the instruction order code and check its own qualifier code contained within its tabulation tables, and then verify the identity and service status of the user, thus completing the autonomous registration procedure. The CCAD data packet is managed in the same manner as the autonomous registration order message. However, the CCAS packet, because of using specially assigned mobile identification number MINI 128 and MIN2 133, is always treated as a roamer or mobile user which has a home serving system that is always perceived as different that the system that it is requesting authentication from or from other types of services.

Referring to FIG. 3, the area code or number plan area (NPA) 133 and central office code 261 cause the serving mobile switching center to always handle the CCAS packet as a roamer packet. Therefore, the CCAD data packet that utilizes autonomous registration order and order qualifier codes combined with unique MIN numbers are processed and preferably sent to the master central monitoring station over the SS7 network. As previously described, the MCMS contains an HLR and SS7 gateway or signaling transfer point STP and is categorized as any other node point or point-of- presence on an SS7 network. The MCMS therefore "looks" like another mobile switching center or other node specified in an IS-41 network. This CCAD method thereby creates an entirely new means and methodology of transmitting data without circumventing current cellular and signaling system standards, this method also causes no problems in such networks. The CCAD packet depicted in FIG. 3 combines the RECC word count in the origination message with the order code and order qualifier code in the autonomous registration message that is part of the order message category. Utilizing the CCAD data packet, the mobile station causes the mobile switching center to except up to seven RECC words in one packet appearing as an origination message that contains A through G words. However, because the CCAD data packet contains the order code 01101 and the order qualifier code Oil that is normally used in an autonomous registration as depicted in FIG. 3, the B word 126 and the mobile switching center and base site treat the CCAD packet as an autonomous registration order message. In this manner, the method described herein allows for the manipulation of existing data to be sent as messages within the guidelines of RECC control channel standards creating a completely new means for providing application specific messaging for AMPS, D-AMPS and TACS cellular standards with the CCAD data packet categorized as an order message.

As further seen in FIG. 3, the C-word is primarily the electronic serial number (ESN) 136 word. Each CCAD communications terminal, be it mobile or stationary has its own electronic serial number. This number contains information that identifies the manufacturer of the terminal, and other pertinent information. The cellular provider uses the ESN to also identify the user, for authentication and account verification. The present invention utilizes the ESN 136 and the SCM 137 as indicators for the aforementioned scanning, recognition and identification process that takes place at the BTS, BSC and MSC. These designated bit fields are also utilized to maintain an accurate transaction count when each CCAD data packet passes through the BTS, BSC, MSC, and MCMS. The facilitator and end user are preferably charged for each CCAD data packet sent from the CCAD communications terminal and no more. H[l] word 131, and H[2] word 132 are shown here to illustrate how each data field is utilized. For example in H[l] digl and dig2 fields 138 are used to identify each application to the MCMS. Digl, indicates a 0 and dig2 indicates a 2, that tells the MCMS that this particular CCAD communications terminal is designed for two-way paging and is provided with a PDA port and can transmit the second CCAD burst. Also, in still yet another configuration the CCAD communicator can be equipped with a GPS receiver and dig3, dig4, and dig 5, 139 indicating a 180 longitude location. Dig6, dig7 and dig8, 140 indicate more detailed longitude degree information 359. H[2] word 132 also contains GPS information and other related status information. For example, digl, dig2, dig3, and dig4, 141 indicate 36.30 degrees latitude. Dig5 and dig6, 142 indicate a 1 and 2, the MCMS recognizes from these numbers reveal a fleet management or personal management version of CCAD communications terminal. This particular CCAD communications terminal is illustrated moving North West, since the 1 indicates North and the 2 indicates West. Dig7, and digδ, 143 indicate other status bits. These two fields are used to signify to the CCAD base site transceiver processing system that the end user request the second packet or burst to be sent that contains an alpha multi-word message that can be read by the receiver in any written language. The present invention's GPS fields can also be used to indicate any end user relative position status, if he is on foot, or traveling in a motor vehicle. The same information can be utilized for motor vehicle anti-theft and recovery.

FIG. 4 is a logic flow diagram of the CCAD data packet being processed at the BTS, BSC, MSC and MCMS. The CCAD communications terminal 100 transmits a CCADCH data packet 103. INPUT 144 represents the BTS and BSC, once received, the CCAD data packet and all other data packets are multi-plexed 145, scanned and rejected as No 147 and data tossed via Exit 148, or identified by electronically detecting the unique CCAD ESN, SCM and second packet I.D. word, and in some instances a special CCAD MIN contained within the data packet, and accepted as YES 149. The processor preferably creates a statistic 150, counts the transaction 151, records the transaction 152, appends the statistical record to the processed CCAD data packet 153, converts the CCAD data packet to Tl/DSO 154 and sends processed CCAD data packet to the MCMS 106 via the PSTN exit 155. Once the CCAD data packet 103 , expressed in directed arrows from the home arrest terminal 100 to the input 114 and the block description CCAD P 101 arrives at the MCMS, the data packet with appended statistics are examined, recorded, processed and various status determinations are made. If the CCAD data packet contains GPS and other pertinent information that signifies to the MCMS a particular requirement to; (a) update a CCAD users location, (b) send an alpha numeric message to cause the user to perform some manual human interface function, (c) send data command message that causes the CCAD communications terminal to automatically respond to the command by transmitting new CCAD data packets in the aforementioned manner, or (d) specially instructs the end user to stand and physically open his communicator to allow for clear line-of-sight access to GPS satellite signals, then the MCMS sends a command and instruction message.

As further shown in FIG. 4, the CCAD communications terminal can receive commands, alpha numeric instructions, and other alpha numeric messages from various communications systems. The CCAD communications terminal may be provided with a paging receiver, a satellite receiver, a cell broadcast receiver or the terminal can receive the aforementioned messaging from the host cellular systems forward analog and digital control channel, analog and digital reverse control channels, paging channels, overhead channels, and digital traffic channels. The MCMS 106 can send instructions and command messages from a paging network

156, or chosen satellite network such as Inmarsat P

157, or by GSM cell broadcast 108.

Referring now to FIG. 5, the methodology of present invention can be used with any control channel, access channel and signaling channel protocol. For example a CCAD data packet can be tagged onto or integrated with an RECC FSK autonomous registration packet 107 with a contained H word 140 and an IS-54/IS-136 DAMPS TDMA access channel and control channel data packet with the application data H word contained in the FACCH field 160 and the user data field. Additionally the CCAD data packet H word can be contained with an IS-95 narrow band spread spectrum CDMA control channel and access 30

channel data field 159. The H word can be made up of a 172 bit CDMA field 161, a 122 bit TDMA user data field 164, and the FACCH field 160, contained within the same data frame.

Referring to FIG. 6 a CCAD master central monitoring station data management system is shown. For example when a CCAD communications terminal, in this case a communicator 100 or paging apparatus 275 shown in FIG. 9, transmits a data packet 107 that contains H words 235, the base transceiver site (BTS) 101 receives the packet, and it is processed at the base site controller (BSC) 102 contained within the base site facility. Preferably data packet 107 is processed in the aforementioned manner at the contained CCAD discriminator 115. All normal control channel information is normally forwarded to the MSC 104, but the CCAD data packet is routed from the MSC to the PSTN via Tl/DSO data format 105 and it is received at the MCMS Tl modem bay 170.

The data reception and distribution terminal 167 first receives the packet, converts it preferably to UNIX data base computer language 166, and forwards packet to the CCAD data packet decoder terminal 168.

Once decoded, the CCAD data packet is forwarded to the comparative data base 169, that reads the decoded data, and determines if further data processing or action is required. If end user or application specific bearer 120 requires action or data. If for example, a two way communicator paging apparatus 275 is configured with a GPS receiver contains longitude and latitude information that needs to be forwarded to a paging bearer facility 120 the GPS data along with other user identification data is sent to the bearer either by the Tl/DSO modem bay or by a direct in- dial modem that is connected to normal four wire and two wire telephone lines. This depends upon how the bearer facility is configured and what data rate is needed by that particular bearer facility 120. In still yet another scenario, if the communicator user is sending E-mail over the Internet utilizing his optional PDA keypad, the MCMS frame relay system 114 forwards this CCAD data utilizing file transfer protocol (FT.), or other transmission control protocol or internet protocol (TCP/IP) to any point-of-presence (POP) located on the world wide web (WWW) . In still another scenario if another land side user is sending internet information to a CCAD communicator user via the MCMS, the MCMS simply forwards the TCP/IP data to the user via the paging network, whereby it is displayed on the CCAD communicator users large LCD display. In still yet another scenario, of the application specific facilitator bearer 120 needs to send a command or instruction to the CCAD communicator user, the follow processes occur. When the comparative data base 169 receives the data in the aforementioned manner, it reads the command or instruction, determines if the particular user is accessed via the paging network. If so, the CAB 169 packetizes the command message, along with paging network routing instructions via the PSTN Tl/DSO 105 to the paging network control center 221 (PNCC), the PNCC reads routing instructions and sends the CCAD command data packet to the paging transmission tower(s) 220 nearest to the last known location of the particular CCAD communicator user. The CCAD paging network packet 108 is preferably coded in hexadecimal language. Or the message can be a simple alpha message or a paged telephone number. Since the CCAD communicator paging receiver is integrated both physically and logically, the message can be a direct electronic data instruction that causes the CCAD communicator to respond to the command automatically without the user even being aware of it. This message can also contain routing instructions sent to a fleet driver, for example, utilizing a CCAD fleet management communicator.

Referring to FIGS. 6 and 7, another significant feature to the CCAD virtual network method, is that it may also utilize the signaling system seven network (SS7) that is currently used world wide by many cellular carriers. SS7 is a PSTN communications platform that was designed to allow cellular switches to talk to one another in a highly efficient manner. This is especially valuable when one serving cellular system in New York 232 is trying to verify the identify of a particular CCAD communicator user. For example, most modern cellular network systems use a home location register (HLR) and a visitor location register (VLR) . An HLR/VCRs are data bases that store cellular subscriber information and act as location registers to which user identify is assigned for record purposes such as subscriber profile information, current location, electronic serial number, validation period, current account status, communicator identification and other pertinent information. The HLR may or may not be located within, and be distinguishable from an MSC. The HLR typically serve more than one MSC and may be distributed over more than one physical entity. The HLR, while directly interacting on an SS7 network, maintains accurate records of current or last known 33 system location of a particular user. For example, a CCAD communicator user whom also has voice service, travels from his home serving system indicated in FIG.. 7, by the Home MSC 231 which could be located in San Francisco California, to a serving cellular system in Los Angeles California or LA MSC 233. He arrives in LA, turns on his communicator and completes a registration procedure. The LA serving cellular system, receives the data, discovers that the user is from out-of-town, i.e., belongs to another cellular serving system, and it is sent to the VLR data base, and it determines that it is the first time this user has registered. The MSC then sends an identification and authentication request to the home MSC 231, the home MSC polls its own HLR, verifies or does not verify the authenticity of the user, and send the data back to the L.A. MSC. The L.A. serving cellular system enters the information in its VLR. However the home MSC is HLR also updates its location data of the CCAD communicator user. The MCMS HLR 162 as depicted in FIG. 6, is also interfaced with the SS7 network, and is simultaneously polled along with the home MSC. The CCAD MCMS also looks and acts like a cellular MSC with its own IS-41 system identification number (SID) and switch number. The CCAD communicator users transmitted data packet contains data bits that identifies him as a CCAD communicator user, via the stations class mark, a distinctive electronic serial number, and a distinctive mobile identification number (MIN) , and causes the SS7 network to send this same authentication request from the L. A. MSC 233 to the CCAD MCMS HLR 162. Both the home cellular system HLR and CCAD HLR update the CCAD communicator users location. This information is important for the CCAD system because this location and visitor MSC signaling transfer point 171 information contained in the authentication update that is sent from the L.A. MSC or other MSC such as Dallas 234 or New York 232 is maintained by the MCMS. Referring to FIG. 6 and 7, if for example, a CCAD communicator user is located in another serving cellular system area, and communicator, the MCMS is alerted. If a message received from a bearer facilitator 120 or from the world wide web 230 is received by the comparative data base 169, and it determines that this message requires the bearer or WWW request to be forwarded, it relays the request to the action data base terminal 119 ADB. The ADB 119 polls the CCAD MCMS HLR 162 to check for last know location of the particular CCAD communicator user. Once this done routing instructions along with the individual message is sent to the near PNCC controller. In another related scenario, the CCAD user does not have to have a normal cellular voice service account in order to utilize a two way paging service with a CCAD communicator. Regardless if a CCAD communicator user chooses to have voice services or not, he is still can sign up for CCAD two way data messaging and paging services. The CCAD MCMS in terms of IS-41 standards is deemed a separate switch, with its on I.D. and signaling transfer point (STP) routing number on the SS7 network, therefore once the CCAD communicator user turns on his phone anywhere in the U.S. the CCAD HLR will be polled and his system location will be updated. The HLR can relate to one or many data bases located around the U.S. that are polled simultaneously. If a communicator user does not choose to have voice services, he is assigned a pseudo MIN number. In FIG. 3, the ten digit mobile identification number (MIN) 128, in this case, is a pseudo MIN number because it cannot be used to contact or call the user from the landline telephone network, and the user cannot place a voice call. However, its number plan area (NPA) or area code 415, its NXX or office code 509, and XXXX code 7471 act as dynamic routing instructions to MSCs and the SS7 network. The NPA relates to system SID and the NXX or office code is the switch number. SS7 signal transfer points (STP) recognize these numbers as dynamic routing numbers. In a nationwide deployment a regional CCAD MCMS is deemed a point-of-presence POP on an SS7 network, therefore CCAD becomes an integral part of the ubiquitous IS-41 world. Another significant aspect of the present methodology is that by sending paging-network- compatible routing instructions to PNCC paging network controllers, CCAD offers a means and a method economizing processing time and transmission capacity of that host paging network. For example, when a person is typically paged, all transmission towers of a particular region, or an entire paging system are caused to transmit a page. By utilizing CCAD SS7 and Tl routing instructions, the capacity of a particular paging network can be saved by knowing before hand, where a particular user is located before the paged message is sent. By combining the signaling characteristics of cellular IS-41 and its HLR/VLR approach, and the network and air-interface signaling characteristics of one-way paging networks, an entirely new paradigm of networking is created; a CCAD virtual network that is incredibly flexible and efficient. The CCAD virtual network is centered around an MCMS that can manage CCAD specific information being sent from hundreds of cellular switches without placing expensive frame relay equipment at each MSC site like cellular digital packet data CDPD and other such systems. The MCMS methodology provides an access means to SS7 and Tl systems. In FIGS. 6 and 7, the action data base 119 ADB, comparative data base 169 CAB and CCAD HLR establish a means of combining two separate networking technologies together, and the CCAD communicator that includes a paging receiver melds two separate air- interface technologies together.

The MCMS can forward the bearer message along with paging network routing instructions to the PNCC 221 which reads the instructions, and forwards the message to the nearest regional paging network controller that in turn sends the message to the nearest single or group of paging network transmission towers that serve the present serving geographic service area (GSA) , that is also served by cellular system, for example, the L.A. serving system 233. This is accomplished without modifying the cellular IS-41 network and the paging signaling network. In this way, CCAD combines all the best attributes of cellular and one way paging to further establish a new virtual network paradigm. The action data base contains all paging network routing information, compares that information with the CCAD MCMS HLR cellular system routing information and thus utilizes codes that are compatible with any host paging network. If, for example, the CCAD communicator is provided with a cell broadcast receiver or satellite receiver, the same type of MCMS routing procedure used for paging networks will apply. Most modern base site 101 have broadcast data protocol capabilities very similar to paging signal protocols. The CCAD MCMS can routes forward messaging into these systems easily utilizing the same IS-41 HLR/VLR scenario. Accordingly, the CCAD MCMS SS7 modem 172 may communicate to all cellular, paging or satellite system SS7 modems, and it interfaces both physically and logically with CCAD MCMS HLR data base 162.

Referring now to FIG. 8, the CCAD communication system is shown within the context of a multi layer model. The CCAD logic structure 255, depicts CCAD logical connections 256, the logical and physical interrelationships of the CCAD air interface and base site transceiver system process column one 257, the CCAD virtual network and MCMS logical and physical interrelationships column two 258, herein referred to as column one 257 and column two 258. Each layer interrelates in a multi matrix manner, and there is no rigid hierarchy, for the multi layer approach creates a holographic means and method of layer inter communications indicated by the arrows 260. The physical channel 259 is part of the physical layer depicted in both column one 257 and column two 258 of the CCAD logical structure 255.

Accordingly, additional advantages and modifications will readily occur to those skilled in the art.

Accordingly, departures may be made from such details without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
