Abstract
In a process for providing mobile application services to a plurality of vehicles through a wireless telecommunications network, an authentication capable, embedded mobile station is provided in each of the vehicles. Each embedded mobile station has a predetermined dialable, non-geographic directory number and provides dialing restricted to one or more predetermined mobile application service directory numbers. A home location register contains profile information for the embedded mobile stations and is connected to the wireless telecommunications network via a service control point. The profile information contains call restriction data allowing routing of calls from the embedded mobile stations through the mobile telecommunications network only to the predetermined mobile application service directory numbers. A mobile application service center provides mobile application services to the vehicles via the embedded mobile stations; and the embedded mobile stations are responsive to calls only from the mobile application service center. The mobile application service center authenticates a11 incoming calls from the embedded mobile stations; and the embedded mobile stations authenticate a11 incoming calls. "One-touch" activation of an embedded mobile station is provided after installation automatically by the mobile application service center upon receipt of a first call by the embedded mobile station. The mobile application service provider accepts all charges from wireless telecommunication service providers and provides a single bill for mobile application services to each subscriber.
Description
METHOD OF PROVIDING MOBILE APPLICATION SERVICES TO
VEHICLES OVER A WIRELESS TELECOMMUNICATIONS NETWORK
TECHNICAL FIELD
The technical field of the invention is the provision of mobile application services to vehicles over a wireless telecommunications network.
BACKGROUND OF THE INVENTION
The development of wireless telecommunications has enabled the provision of mobile application services to vehicles throughout most of North America by mobile application service providers such as GM OnStar ~.
Call-in service for Global Positioning System (GPS) determined vehicle location or directions to a desired vehicle destination, tracking of stolen vehicles, automatic notification of supplemental inflatable restraint (SIR) activation with dispatch of emergency services, and notification of a vehicle security system violation are examples of the mobile application services now available to properly equipped vehicles; and such mobile application services have provided improved convenience and security to vehicle operators.

BACKGROUND OF THE INVENTION
The development of wireless telecommunications has enabled the provision of mobile application services to vehicles throughout most of North America by mobile application service providers such as GM OnStar ~.
Call-in service for Global Positioning System (GPS) determined vehicle location or directions to a desired vehicle destination, tracking of stolen vehicles, automatic notification of supplemental inflatable restraint (SIR) activation with dispatch of emergency services, and notification of a vehicle security system violation are examples of the mobile application services now available to properly equipped vehicles; and such mobile application services have provided improved convenience and security to vehicle operators.
Mobile application services have been provided to vehicles equipped with mobile stations operating in cellular geographic service areas (CGSAs) of North America. These mobile stations are familiar cellular telephones, with general dialing capabilities in addition to any push-button activated automatic dialing. To support general dialing, such cellular telephones are registered with a cellular wireless telecommunications service provider. Thus, to receive mobile application services in a vehicle, a subscriber must enter into separate agreements with two providers: (1) a provider of the mobile application services themselves, and (2) a provider of
2 wireless telecommunication services in a home CGSA. This results in problems for the subscriber and for both providers.
One such problem is that each subscriber receives two separate bills: one from the mobile application service provider and one from the wireless telecommunication service provider. This can create confusion for subscribers and generate extra billing costs.
Another problem is undesirable cost and service variation to subscribers. Although the mobile application service provider can provide consistent services at consistent prices throughout the wireless telecommunications network, the costs and service level for wireless telecommunications services, which are billed separately by the wireless telecommunication service providers, can vary significantly from one provider or CGSA to the next. There are 734 CGSAs in the United States; and each such CGSA is allowed two competing cellular service providers - the "A-side" and the "B-side" providers - which generally vary from one CGSA to another. The cost of wireless telecommunication service within these areas varies from one CGSA to another, as does the level of service provided. Use of the mobile station outside the home CGSA - known as "roaming" -depends on roaming agreements between the subscriber's cellular service provider and the cellular service providers in other CGSAs through which the subscriber travels. Roaming charges thus tend to vary greatly and unpredictably throughout the wireless telecommunications network. Similar problems exist in the Personal Communication Service (PCS) band.
Yet another problem is inconvenience in the installation and programming of the mobile station. A mobile application service provider may provide and install a mobile station pre-programmed for the mobile application services, and may provide "over-the-air" programming changes of these services; but the mobile station must also be activated by the wireless telecommunication service provider for use in the wireless telecommunications network. Any change in the wireless telecommunications service provider, either because of a move by the subscriber to a different CGSA or because of

Any change in the wireless telecommunications service provider, either because of a move by the subscriber to a different CGSA or because of
3 a change in providers in a CGSA for lower prices or better service, requires reprogramming of the mobile station by the new wireless telecommunication service provider. Such reprogramming generally requires an inconvenient visit to a facility of the new wireless telecommunications service provider.
Fraud is another problem which is shared by all users of wireless telecommunications equipment. At times, mobile stations are required to broadcast identifying information such as the phone mobile identification number (MIN) and equipment serial number (ESN), which can be intercepted and programmed into another mobile station. The other mobile station is a clone which imitates the legitimate mobile station in the system and thus fraudulently shifts charges for system use to the legitimate mobile station.
The widespread fraud problem has led to the introduction of authentication methods in wireless telecommunications based on authentication keys in mobile stations and network equipment which are not broadcast and thereby cannot be intercepted. But, due to the expense of converting equipment, many cellular service providers, particularly in less populated CGSAs, have not implemented this technology. Thus, the level of protection against fraud also varies widely across the wireless telecommunications network. In addition to fraudulent charge shifting, fraudulent use of the network consumes limited network bandwidth which is not available to legitimate users. Also, because wireless telecommunication service providers often absorb the costs of fraudulent calls, much time and effort is expended by such providers in reaching agreements with each other to apportion these costs. Thus, the prior art arrangement for providing mobile application services over the wireless telecommunications network results in confusion, inconvenience and extra cost.

SUMMARY OF THE INVENTION
The process of this invention restricts use of the mobile stations in vehicles to the provision of mobile application services and places the mobile application service provider in control of the marketing and delivery of
4 these services over the wireless telecommunications network. In so doing, the process provides a new class of service in the wireless telecommunications network which reduces cost and confusion, improves convenience and substantially eliminates fraud. The process also creates, in effect, a new virtual network overlaying and using the wireless telecommunications network to connect a mobile application service provider to its subscribers.
In this process, embedded mobile stations are provided in vehicles. Each embedded mobile station is authentication capable, has a predetermined dialable, non-geographic mobile identification number, and provides programmed dialing restricted to one or more predetermined mobile application service directory numbers. A home location register containing identification and profile information for the embedded mobile stations is connected to the wireless telecommunications network via a service control point. A mobile application service center provides mobile application services to the vehicles via the embedded mobile stations. The embedded mobile stations are responsive to calls only from the mobile application service center.
In addition, the home location register is programmed to restrict calls from the embedded mobile stations to the predetermined mobile application service directory numbers. Furthermore, the mobile application service center authenticates all incoming calls from the embedded mobile stations, and the embedded mobile stations authenticate all incoming calls.
The restrictions on calls from the embedded mobile stations to the mobile application service center ensure that any call from a mobile station identifying itself as an embedded mobile station is routed only to the mobile application service center, where it is subjected to authentication independent of any provided elsewhere in the wireless telecommunication network. Even if a mobile station is cloned, the clone could not complete any call over the wireless telecommunications network except to the mobile application service center; and such a completed call would be dropped when authentication failed. The clone would thus be useless. Likewise, authentication of all S
incoming calls by the mobile units ensures that only calls from the mobile application service center are completed to the mobile stations. Fraud is essentially eliminated in the provision of mobile application services.
The process is managed by the mobile application service provider, which provides the mobile stations to controlled specifications, maintains a home location register for the mobile stations, provides specifications for the new class of service to necessary entities in the wireless telecommunications network, and authenticates all calls in the provision of mobile application services. The mobile application service provider is thus able to manage its risks and costs to provide lower rates to its subscribers.
Furthermore, there is no need for support to the subscriber by the wireless telecommunication service providers. The mobile application service provider may enter into agreements with all wireless telecommunication service providers whereby it assumes all subscriber service responsibilities and charges involved in the provision of the mobile application services via the mobile stations. Thus, the subscribers subscribe for services only from the mobile application service provider and receive a single bill for the provision of mobile application services to their mobile stations. The mobile application service provider negotiates with the wireless telecommunication service providers on a continuing basis to obtain consistent service at the lowest available rates for wireless telecommunication services in all geographic service areas and provides "over-the-air" programming of embedded mobile stations, in a manner transparent to the subscriber, when preferred wireless telecommunication service providers are changed.
The process provides benefits to the wireless telecommunication service providers. The substantial elimination of fraud in the provision of mobile application services frees bandwidth for legitimate network users and lowers costs, particularly for those providers who have not adopted call authentication. The assumption of customer service for the embedded mobile stations by the mobile application service provider lowers costs and reduces customer confusion and complaints. For these and other reasons, it is anticipated that the new class of service will be less costly and will thus attract more subscribers for the mobile application service provider. The increase in subscribers will result in increased business to the wireless telecommunication service providers at a lower operating cost.

DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 1 shows a network model of a mobile application service network using a wireless telecommunications network. The model shows functional entities in a manner consistent with specification ANSI/TIA/EIA-41 ("IS-41 "); the actual apparatus used is known to those skilled in the art, except as described herein.
Referring to FIG. 1, vehicle 10 is mobile: either self-propelled (a motor vehicle) or propelled by another (a trailer). Vehicle 10 is provided with an embedded mobile station (MS) 11 capable of two-way radio communication with a fixed base station (BS) 20 having an antenna 22. MS
11 communicates with BS 20 within a limited coverage area around BS 20, as well as with other base stations as it moves through their limited coverage areas. BS 20 is connected by land communication lines to a mobile switching center (MSC) which, because it is shown as currently serving MS 11, will be referred to as the serving mobile switching center (SMSC) 30.
Base station 20 and SMSC 30 are operated by a wireless telecommunication service provider in a defined geographic service area.
SMSC 30 is part of a wireless telecommunications network providing mobile stations such as MS 11 communication capability with other stations, either mobile or stationary. In this embodiment, MS 11, BS 20 and SMSC 30 preferably operate in the cellular license band, but they are not limited to such operation: the personal communications (PCS) band and others are alternatives .
In addition to BS 20 and SMSC 30, the wireless telecommunications network comprises at least a digital signaling network 35 (ISDN, SS7, X-25) capable of carrying IS-41 data messages and a public switched telephone network (PSTN) 40 capable of carrying voice and data transmissions. Digital signaling network 35 and PSTN 40 extend over a large geographical area - potentially all of North America - over which mobile application services are provided to moving vehicles. SMSC 30 is further connected to a visitor location register (VLR) 32 containing temporary location, status and service information concerning MS 11 and other mobile stations registered as visitors with SMSC 30. SMSC 30 may optionally be connected to an authentication center (AC) 33 for performing authentication g functions relative to mobile stations, including MS 11, attempting access thereto.
MS 11 is a subscriber to a mobile application service provider having a mobile application service center (MASC) 42 connected to the wireless telecommunications network via PSTN 40. The mobile application service provider is a business concern that provides mobile application services to vehicles via the wireless telecommunications network. These mobile application services may include vehicle operator call-in services such as providing GPS determined vehicle location to a lost driver, providing directions to a desired vehicle destination or tracking a stolen vehicle, and may include automatic vehicle interface services such as notification of supplemental inflatable restraint activation with consequent dispatch of emergency services, or notification of a vehicle security system violation.
The provider of these application services via the wireless telecommunications network may or may not be also a provider of telecommunication services in the network itself. In this preferred embodiment, the mobile application service provider is a manufacturer of vehicles and provides these services, as well as the embedded mobile stations used in providing these services, to the purchasers and other operators of those vehicles.
MASC 42 is operated by the mobile application service provider and includes communication stations staffed by operators who receive calls to MASC 42 from MS 11 and other mobile stations and also communicate with information data providers, government and emergency service providers and others in order to provide the mobile application services requested or required by the operators and systems of vehicle 10 and other vehicles having embedded mobile stations. It should be clear that a mobile application service provider having a large number of subscribers over a diverse area may provide staffed communication stations in a plurality of locations; and a11 are considered part of MASC 42 for purposes of this description. MASC 42 also has authentication capability with MS 11 and all other embedded mobile stations and performs authentication on all incoming calls from embedded mobile stations.
The mobile application service provider also provides and maintains a home location register (H:LR) 48, connected via a service control point (SCP) 46 to digital signaling network 35 and public switched telephone network (PSTN) 40. HLR 48 contains subscriber profile data for all embedded mobile stations, the data including such information as MS location, subscriber status, call restrictions and directory numbers. As will be more fully described at a later point in this description, the call restrictions in HLR
48 for MS 1 I and other embedded mobile stations allow routing of calls from these mobile stations through the mobile telecommunications network only to MASC 42. If more than one physical home location register is provided, each contains the basic subscriber data, including call restrictions, for all subscribers. A separate communication link, indicated by dashed line 45 in FIG. 1, may be provided between HLR 48 and MASC 42 to facilitate data flow in providing enhanced mobile application services.
Mobile station (MS) 11 is shown with its vehicle interfaces in FIG. 2. The heart of MS 11 is transceiver 12, which is manufactured by or to the specifications of the mobile application service provider and is provided by the mobile application service provider to be installed as an embedded unit within vehicle 10. It may be installed by the mobile application service provider itself, by an automotive dealer, or by another installer on behalf of the mobile application service provider. The word "embedded" means that it is installed in the vehicle and intended for use in the provision of application services to the vehicle, and further means that it is a subscriber of the mobile application services provided. In this embodiment, transceiver 12 is technically capable of operating in either the "A" or the "B" portions of the cellular band, but mobile stations using similar technologies, such as the PCS
band, are also possible.
Transceiver 12 is provided with electric power from a DC
electric power supply 50, which may be the normal vehicle DC power supply or a supplemental DC power supply, and is connected by an RF connection to antenna 14. A control and interface 57 provides interfacing and co-ordination with vehicle systems and accessories. For example, a speaker 52 and microphone 54 are used for voice communications to and from transceiver 12.
In this process, embedded mobile stations are provided in vehicles. Each embedded mobile station is authentication capable, has a predetermined dialable, non-geographic mobile identification number, and provides programmed dialing restricted to one or more predetermined mobile application service directory numbers. A home location register containing identification and profile information for the embedded mobile stations is connected to the wireless telecommunications network via a service control point. A mobile application service center provides mobile application services to the vehicles via the embedded mobile stations. The embedded mobile stations are responsive to calls only from the mobile application service center.
In addition, the home location register is programmed to restrict calls from the embedded mobile stations to the predetermined mobile application service directory numbers. Furthermore, the mobile application service center authenticates all incoming calls from the embedded mobile stations, and the embedded mobile stations authenticate all incoming calls.
The restrictions on calls from the embedded mobile stations to the mobile application service center ensure that any call from a mobile station identifying itself as an embedded mobile station is routed only to the mobile application service center, where it is subjected to authentication independent of any provided elsewhere in the wireless telecommunication network. Even if a mobile station is cloned, the clone could not complete any call over the wireless telecommunications network except to the mobile application service center; and such a completed call would be dropped when authentication failed. The clone would thus be useless. Likewise, authentication of all S
incoming calls by the mobile units ensures that only calls from the mobile application service center are completed to the mobile stations. Fraud is essentially eliminated in the provision of mobile application services.
The process is managed by the mobile application service provider, which provides the mobile stations to controlled specifications, maintains a home location register for the mobile stations, provides specifications for the new class of service to necessary entities in the wireless telecommunications network, and authenticates all calls in the provision of mobile application services. The mobile application service provider is thus able to manage its risks and costs to provide lower rates to its subscribers.
Furthermore, there is no need for support to the subscriber by the wireless telecommunication service providers. The mobile application service provider may enter into agreements with all wireless telecommunication service providers whereby it assumes all subscriber service responsibilities and charges involved in the provision of the mobile application services via the mobile stations. Thus, the subscribers subscribe for services only from the mobile application service provider and receive a single bill for the provision of mobile application services to their mobile stations. The mobile application service provider negotiates with the wireless telecommunication service providers on a continuing basis to obtain consistent service at the lowest available rates for wireless telecommunication services in all geographic service areas and provides "over-the-air" programming of embedded mobile stations, in a manner transparent to the subscriber, when preferred wireless telecommunication service providers are changed.
The process provides benefits to the wireless telecommunication service providers. The substantial elimination of fraud in the provision of mobile application services frees bandwidth for legitimate network users and lowers costs, particularly for those providers who have not adopted call authentication. The assumption of customer service for the embedded mobile stations by the mobile application service provider lowers costs and reduces customer confusion and complaints. For these and other reasons, it is anticipated that the new class of service will be less costly and will thus attract more subscribers for the mobile application service provider. The increase in subscribers will result in increased business to the wireless telecommunication service providers at a lower operating cost.

DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 1 shows a network model of a mobile application service network using a wireless telecommunications network. The model shows functional entities in a manner consistent with specification ANSI/TIA/EIA-41 ("IS-41 "); the actual apparatus used is known to those skilled in the art, except as described herein.
Referring to FIG. 1, vehicle 10 is mobile: either self-propelled (a motor vehicle) or propelled by another (a trailer). Vehicle 10 is provided with an embedded mobile station (MS) 11 capable of two-way radio communication with a fixed base station (BS) 20 having an antenna 22. MS
11 communicates with BS 20 within a limited coverage area around BS 20, as well as with other base stations as it moves through their limited coverage areas. BS 20 is connected by land communication lines to a mobile switching center (MSC) which, because it is shown as currently serving MS 11, will be referred to as the serving mobile switching center (SMSC) 30.
Base station 20 and SMSC 30 are operated by a wireless telecommunication service provider in a defined geographic service area.
SMSC 30 is part of a wireless telecommunications network providing mobile stations such as MS 11 communication capability with other stations, either mobile or stationary. In this embodiment, MS 11, BS 20 and SMSC 30 preferably operate in the cellular license band, but they are not limited to such operation: the personal communications (PCS) band and others are alternatives .
In addition to BS 20 and SMSC 30, the wireless telecommunications network comprises at least a digital signaling network 35 (ISDN, SS7, X-25) capable of carrying IS-41 data messages and a public switched telephone network (PSTN) 40 capable of carrying voice and data transmissions. Digital signaling network 35 and PSTN 40 extend over a large geographical area - potentially all of North America - over which mobile application services are provided to moving vehicles. SMSC 30 is further connected to a visitor location register (VLR) 32 containing temporary location, status and service information concerning MS 11 and other mobile stations registered as visitors with SMSC 30. SMSC 30 may optionally be connected to an authentication center (AC) 33 for performing authentication g functions relative to mobile stations, including MS 11, attempting access thereto.
MS 11 is a subscriber to a mobile application service provider having a mobile application service center (MASC) 42 connected to the wireless telecommunications network via PSTN 40. The mobile application service provider is a business concern that provides mobile application services to vehicles via the wireless telecommunications network. These mobile application services may include vehicle operator call-in services such as providing GPS determined vehicle location to a lost driver, providing directions to a desired vehicle destination or tracking a stolen vehicle, and may include automatic vehicle interface services such as notification of supplemental inflatable restraint activation with consequent dispatch of emergency services, or notification of a vehicle security system violation.
The provider of these application services via the wireless telecommunications network may or may not be also a provider of telecommunication services in the network itself. In this preferred embodiment, the mobile application service provider is a manufacturer of vehicles and provides these services, as well as the embedded mobile stations used in providing these services, to the purchasers and other operators of those vehicles.
MASC 42 is operated by the mobile application service provider and includes communication stations staffed by operators who receive calls to MASC 42 from MS 11 and other mobile stations and also communicate with information data providers, government and emergency service providers and others in order to provide the mobile application services requested or required by the operators and systems of vehicle 10 and other vehicles having embedded mobile stations. It should be clear that a mobile application service provider having a large number of subscribers over a diverse area may provide staffed communication stations in a plurality of locations; and a11 are considered part of MASC 42 for purposes of this description. MASC 42 also has authentication capability with MS 11 and all other embedded mobile stations and performs authentication on all incoming calls from embedded mobile stations.
The mobile application service provider also provides and maintains a home location register (H:LR) 48, connected via a service control point (SCP) 46 to digital signaling network 35 and public switched telephone network (PSTN) 40. HLR 48 contains subscriber profile data for all embedded mobile stations, the data including such information as MS location, subscriber status, call restrictions and directory numbers. As will be more fully described at a later point in this description, the call restrictions in HLR
48 for MS 1 I and other embedded mobile stations allow routing of calls from these mobile stations through the mobile telecommunications network only to MASC 42. If more than one physical home location register is provided, each contains the basic subscriber data, including call restrictions, for all subscribers. A separate communication link, indicated by dashed line 45 in FIG. 1, may be provided between HLR 48 and MASC 42 to facilitate data flow in providing enhanced mobile application services.
Mobile station (MS) 11 is shown with its vehicle interfaces in FIG. 2. The heart of MS 11 is transceiver 12, which is manufactured by or to the specifications of the mobile application service provider and is provided by the mobile application service provider to be installed as an embedded unit within vehicle 10. It may be installed by the mobile application service provider itself, by an automotive dealer, or by another installer on behalf of the mobile application service provider. The word "embedded" means that it is installed in the vehicle and intended for use in the provision of application services to the vehicle, and further means that it is a subscriber of the mobile application services provided. In this embodiment, transceiver 12 is technically capable of operating in either the "A" or the "B" portions of the cellular band, but mobile stations using similar technologies, such as the PCS
band, are also possible.
Transceiver 12 is provided with electric power from a DC
electric power supply 50, which may be the normal vehicle DC power supply or a supplemental DC power supply, and is connected by an RF connection to antenna 14. A control and interface 57 provides interfacing and co-ordination with vehicle systems and accessories. For example, a speaker 52 and microphone 54 are used for voice communications to and from transceiver 12.
5 Other accessories and monitored vehicle systems may provide digital data through control and interface 57 apparatus to transceiver 12. For example, GPS receiver 55, which includes an antenna, not shown, provides vehicle position information used by MASC 42 to locate vehicle 10. Supplemental inflatable restraint (SIR) control 56 may provide an SIR activation signal from 10 a vehicle crash sensor, not shown, whereupon control and interface apparatus 57 will initiate a call from MS 11 to notify MASC 42 of a possible crash.
Likewise, vehicle security system 58 may provide a security violation signal, whereupon control and interface apparatus 57 will initiate a call from MS 11 to notify MASC 42 of a possible vehicle security problem. Control and interface apparatus 57 may comprise a programmed digital computer. This and apparatus described in this paragraph may be essentially the same as that already used in the commercially available GM OnStar ~ system.
An operator call-in activation interface 60 is simple and limited:
preferably one or more dedicated push-button or similar one-touch activators, each providing automatic dialing of a preprogrammed directory number.
Push-button activated switch 61, used for non-emergency calls, is programmed to dial a directory number of MASC 42. This is preferably a non-geographic dialable directory number, such as an "800" number, which provides direct connection to MASC 42 over PSTN 40 from any serving mobile switch center such as SMSC 30. Push-button activated switch 62 is used for emergency calls. It may be programmed to dial the same directory number as push-button activated switch 61, in which case the resulting call provides call identification indicating an emergency. Alternatively, it may be programmed to dial a similar but different dialable directory number to MASC
42, which number is used for emergency calls. One or more additional such push-buttons may be provided as desired, with or without additional dialable numbers .
Transceiver 12 of MS 11 is provided with identification data comprising a non-geographic, dialable, mobile identification number (MIN), S and an equipment serial number (ESN), and this data is stored in HLR 48 as part of its profile data. The MIN of MS 11 is preferably an N00-NXX-XXXX
non-geographic Service Access Code as specified in the Industry Carriers Compatibility Forum (ICCF) Personal Communications Services N00 NXX
Code Assignment Guidelines.
MS 11 is restricted to calling only the preprogrammed numbers) of MASC 42. Call restrictions are provided as part of the profile data for MS 11 and other embedded mobile stations in HLR 48; and these restrictions will be provided to any querying entity of the wireless telecommunications network to prevent routing of calls from MS 11 and other embedded mobile stations to any directory numbers other than those of MASC
42. Additionally, the call restrictions may be provided in technical specification sheets to wireless telecommunication service providers operating mobile switching centers in the wireless telecommunications network; and mobile switching centers having sufficiently capable equipment may be programmed to provide call routing from MS 11 and other embedded mobile stations only to MASC 42 based on the mobile stations' mobile identification numbers, without the necessity of querying HLR 48.
The process of providing mobile application services to vehicle 10 over the wireless telecommunications network of FIG. 1 is shown in the process flow chart of FIG. 5. The steps are shown not necessarily in the order of performance, but in an order facilitating explanation. The mobile application service provider provides (100) MS 11 for installation as an embedded mobile station in vehicle 10. The mobile application service provider may itself manufacture MS 11; but it is more likely that MS 11 will be manufactured by a supplier to a set of specifications from the mobile application service provider. These specifications include the non-geographic, dialable MIN. In addition, MS 11 has mutual call authentication capability with respect to MASC 42: each is able to authenticate a call received to verify that it comes from the other. The specifications for MS 11 further provide that a11 calls to MS 11 will be dropped except authenticated calls from MASC
42, as further described below.
The step of providing MS 11 includes installation and activation of MS 11 in vehicle 10, which is shown in the process flow chart of FIG. 6.
Referring to FIG. 6, a purchaser, most likely the vehicle owner, first subscribes (120) for mobile application services to vehicle 10 with an installer.
The installer provides (l21) subscriber data to MASC 42, the including information being at least sufficient to associate an MS 11 with the subscriber and vehicle 10. The installer then physically installs (122) mobile station 11 in vehicle 10, if it is not already installed. Mobile station 11 is already registered in HLR 48; and the installer is thus able to initiate (123) a first call from MS 11 to MASC 42 by pressing one of the push-button switches in vehicle 10. The call is connected to MASC 42 in the manner described below in connection with FIG. 3A and 3B. MASC 42 recognizes the MIN and ESN
of mobile station 11 as identifying an installed embedded mobile station and automatically activates (124) MS 11. Mobile station 11 is now ready for use in providing mobile application services to vehicle 10. This "one-touch"
installation process is possible because the mobile application service provider retains control of all steps of the process, including activation of embedded mobile stations.
Returning to FIG. 5, the mobile application service provider provides ( 101 ) HLR 48 and programs it with profile information for the manufactured mobile stations. The mobile application service provider also provides SCP 46 for connecting HLR 48 to the wireless telecommunications network: specifically to digital signaling network 35 and PSTN 40. Either or both of HLR 48 and SCP 46 may be physically designed, built and/or maintained by a telecommunication service provider on behalf of the mobile application service provider, but the latter controls the profile information contained in HLR 48.
The mobile application service provider provides (102) MASC
42 and operates it in the provision of mobile application services to vehicle and other vehicles via the embedded mobile stations. MASC is authentication capable; and the mobile application service provider performs (103) authentication in MASC 42 of all incoming calls from MS 11 and all other mobile stations, as described below in connection with FIG. 3A and 3B. In order that only calls from MASC 42 may be received by MS 11, the latter performs (104) authentication of all incoming calls, as described further below with reference to FIG. 4A and 4B.
A call from vehicle 10 to MASC 42 is completed in the following manner, with reference to FIG. 3A and 3B and assuming that MS
11 is already registered as a roamer with SMSC 30. When a call is initiated, either automatically in response to a vehicle system event or by a vehicle operator activating one of push-buttons 61 or 62, the appropriate directory number for MASC 42 is automatically dialed (66) and a call-initiating data message signals (67) base station (BS) 20. BS 20 sets up (68) circuits to SMSC 30, which queries (69) VLR 32 for service qualification, call restrictions and routing. VLR 32 answers (70) with information including the call restrictions to the directory numbers(s) of MASC 42 and the routing for those numbers obtained from HLR 48 during roamer registration of MS 11.
The dialed number is compared (71) to the restricted MASC numbers, and if there is no match, the call is dropped (72). If there is a match, SMSC 30 routes (73) the call through PSTN 40 to MASC 42. At the beginning of the call, authentication data is transmitted to MASC 42. MASC 42 is authentication capable for a11 embedded mobile stations and challenges the call (74) in an authentication process. If the call is not authenticated, it is dropped (75). If it is authenticated, the call is continued to completion (76).
Important features of this process for providing mobile application services to a plurality of vehicles are illustrated in the above-described call process. The restrictions on calls from the embedded mobile stations ensure that any call from a mobile station or telephone identifying itself as one of the embedded mobile stations will be routed only to MASC 42, where it must be authenticated by MASC 42 or dropped. Thus, although MS
11 can be cloned, the mobile station clone cannot be used for anything useful.
Control over this process is entirely with the mobile application service provider, which provides the embedded mobile stations, provides the call restriction information via HLR 48 and technical specifications to wireless telecommunication service providers, and provides authentication of a11 calls from the embedded mobile stations.
A call from MASC 42 to MS 11 is completed in the following manner, with reference to FIG. 4A and 4B. The call is initiated in MASC 42, which dials (80) the MIN of MS 11. The call is routed (81) through PSTN 40 to the home network of MS 11 and all other mobile stations in the mobile application service network, at SCP 46. 5CP 46 queries (82) HLR 48 for registration, location and routing information. HLR 48 queries (83) VLR 32 for routing information via digital signaling network 35. VLR 32 passes on the routing query (84) to SMSC 30; and SMSC 30 returns (85) a temporary local directory number (TLDN) to VLR 32. VLR 32 passes on the TLDN
(86) through HLR 48 to SCP 46, which then routes the call (87) through PSTN 40 to SMSC 30 using the TLDN. SMSC 30 routes the call (88) to BS
20, which completes the connection through the air to MS 11. Upon receipt of the call, MS 11 challenges (89) the call in an authentication process. If the call is not authenticated, it is dropped (90). If the call is authenticated, it is continued (91) to completion.
The billing and subscriber service arrangement for the provision of mobile application services are described with reference to the process flow chart of FIG. 7. The mobile application service provider enters into agreements with the wireless telecommunication service providers on the wireless telecommunications network (l31) to take a11 charges generated and provide a11 subscriber support in the provision of the mobile application services to its subscribers. These agreements, based on a new class of service, may provide for lower charges due to projected or demonstrated cost savings resulting from the process described herein. The wireless telecommunication service providers bill the mobile application service 5 provider for the charges; and the mobile application service provider pays (132) the wireless telecommunication service providers for these charges and combines these charges with their own charges for mobile application services so as to present (133) a single bill to each subscriber. The mobile application service provider also provides all subscriber support as required. The mobile 10 application services provider is able to negotiate the best rates and service in each geographic service area and is capable of reprogramming (134) mobile stations "over-air" when switching preferred wireless telecommunication service providers.
A11 parties are expected to benefit from this process. The 15 telecommunication service providers experience a cost reduction in providing billable air time. Many wireless telecommunication service providers will also experience a freeing of bandwidth due to reduction in fraudulent use of their facilities. The mobile application service provider benefits from the ability to provide lower and more consistent rates and a consistent level of support to subscribers. Subscribers benefit from a single, lower bill, better support, no special return trips to a dealer for reprogramming, and less confusion as to whom to contact with questions or problems.
Likewise, vehicle security system 58 may provide a security violation signal, whereupon control and interface apparatus 57 will initiate a call from MS 11 to notify MASC 42 of a possible vehicle security problem. Control and interface apparatus 57 may comprise a programmed digital computer. This and apparatus described in this paragraph may be essentially the same as that already used in the commercially available GM OnStar ~ system.
An operator call-in activation interface 60 is simple and limited:
preferably one or more dedicated push-button or similar one-touch activators, each providing automatic dialing of a preprogrammed directory number.
Push-button activated switch 61, used for non-emergency calls, is programmed to dial a directory number of MASC 42. This is preferably a non-geographic dialable directory number, such as an "800" number, which provides direct connection to MASC 42 over PSTN 40 from any serving mobile switch center such as SMSC 30. Push-button activated switch 62 is used for emergency calls. It may be programmed to dial the same directory number as push-button activated switch 61, in which case the resulting call provides call identification indicating an emergency. Alternatively, it may be programmed to dial a similar but different dialable directory number to MASC
42, which number is used for emergency calls. One or more additional such push-buttons may be provided as desired, with or without additional dialable numbers .
Transceiver 12 of MS 11 is provided with identification data comprising a non-geographic, dialable, mobile identification number (MIN), S and an equipment serial number (ESN), and this data is stored in HLR 48 as part of its profile data. The MIN of MS 11 is preferably an N00-NXX-XXXX
non-geographic Service Access Code as specified in the Industry Carriers Compatibility Forum (ICCF) Personal Communications Services N00 NXX
Code Assignment Guidelines.
MS 11 is restricted to calling only the preprogrammed numbers) of MASC 42. Call restrictions are provided as part of the profile data for MS 11 and other embedded mobile stations in HLR 48; and these restrictions will be provided to any querying entity of the wireless telecommunications network to prevent routing of calls from MS 11 and other embedded mobile stations to any directory numbers other than those of MASC
42. Additionally, the call restrictions may be provided in technical specification sheets to wireless telecommunication service providers operating mobile switching centers in the wireless telecommunications network; and mobile switching centers having sufficiently capable equipment may be programmed to provide call routing from MS 11 and other embedded mobile stations only to MASC 42 based on the mobile stations' mobile identification numbers, without the necessity of querying HLR 48.
