Title: System and method for subscription based deployment and management of a communication system

Description:
FIELD OF THE INVENTION 
     The present invention relates generally to communication systems and more particularly to facilitating subscriptions that facilitate the deployment and management of converged communication devices. 
     BACKGROUND 
     In the past and even in many of today&#39;s communication environments, land mobile radios (LMR) have operated over a narrowband network for use in public safety environments, such as law enforcement, fire rescue, and the like, while smartphone devices, on the other hand, have operated over broadband networks for other business or consumer oriented applications. However, the expansion of broadband is reshaping the world of public safety. In situations where different organizations may desire to interoperate with each other, the larger availability of broadband frequencies, along with the applications supported by broadband, such as telephony, text, and video, imaging and multimedia applications, makes the idea of converging LMR features for operation within a broadband system an attractive approach to communication. The ability to use a broadband network as a back-up for LMR mission critical functionality is also highly desirable for cases in which the LMR narrowband system may become temporarily unavailable. 
     However, the desire to have public safety LMR features that will operate over broadband comes with many challenges. For example, the ability to appropriately prioritize public safety LMR features, such as public safety push-to-talk (PTT) and other applications related to public safety, face challenges associated with the fact that certain broadband operating systems prioritize telephony calls, over incoming public safety calls. From the user standpoint, there is a need, particularly for those users operating in public safety environments, to have quick access to a public safety features and functions. From a device and services standpoint, there is a need for service providers to manage feature subscriptions and billing across multiple different providers. 
     Accordingly, it would be desirable to facilitate deployment and management of a communications system formed of converged mobile communication devices, including management of service subscriptions, across LMR narrowband and broadband networks.

     DETAILED DESCRIPTION 
     Briefly, there is described herein a system and method for subscription based deployment and management of a communication system. For the purposes of this application, Land Mobile Radio (LMR), also called public land mobile radio or private land mobile radio, is a wireless communications system intended for use by terrestrial users in vehicles and/or on foot. Communication devices operating in such a system will generally be referred to by the term mobile communication devices. Examples are two way radios in vehicles or worn on the body. Such systems are used by emergency first responder organizations such as police, fire, and ambulance services, public works organizations, dispatched services such as taxis, or companies with the need for large fleet management. For the purposes of this application, LMR is considered a narrowband system which is further connected to other systems, those other systems being broadband systems, for example: cellular networks, such as Long Term Evolution (LTE), a wireless local area network system, such as WiFi, BLUETOOTH, personal area network (PAN), internet systems, and/or other broadband systems known or yet to be developed. The embodiments provided herein are directed to providing a communication system that enables subscription based deployment and fleet management of purposely built mobile communication devices. 
       FIG. 1  is a block diagram of a communication system  100  formed and operating in accordance with some embodiments. The communication system  100  comprises an ordering system  102 , a data storage memory  104 , a service management system  106 , a bearer management system  108 , a plurality of different bearer providers  110 , and a device/gateway management system  112 , all communicatively coupled (wirelessly, wired, or combination thereof) to a communications network  114  for subscription based deployment and management of services to a plurality of remote mobile communication devices  116  over one or more gateways  118 . For the purposes of this application, the term ‘services’ encompasses features, bearer providers, and capabilities. Features are associated with a mobile device or a user, for example push-to-talk (PTT), device management, location, and virtual assistant, to name a few; bearer providers are associated with the system, for example LMR, LTE, WiFi, Bluetooth, 5G cellular to name a few; and capabilities are associated with measurable parameters of a bearer provider, for example quality of service (QoS) of a bearer provider, availability of a bearer provider, duration of time anticipated for use a bearer provider, number of calls to be processed by the bearer provider, data rate of a bearer provider, and time duration of calls processed through a bearer provider, to name a few. 
     In accordance with some embodiments, the ordering system  102  generates subscription offerings  103  and receives subscription orders from a customer for provisioning the plurality of remote mobile communication devices  116  and configuring the one or more gateways  118  in via communication network  114 . The ordering system  102  may comprise for example, a dedicated order console, web based ordering portal, or other suitable order entry database. The subscription offerings and orders generated in response thereto comprise one or more of: device based subscriptions and/or user based subscriptions. Device based subscriptions offer services tied to one or more specific devices of the plurality of mobile devices  116  and required gateways  118 . User based subscriptions offer services associated with a particular end user and required gateway  118 . Further description of device based subscriptions and user based subscriptions will be provided later. In accordance with some embodiments, the subscription offerings define features, bearer type, and capabilities needed for a device and gateway, however the aspects of bearer type and capabilities remain transparent to the customer entering an order request as well as the end user utilizing the device. Hence, the customer may request a feature for one or more devices but need not be encumbered with the details as to bearer type or capabilities, thereby providing for an improved transparent interface to the customer. Likewise an end user may be notified or become aware of new or improved features, but that end user will not be encumbered with details pertaining to bearer type or capabilities. This is particularly advantageous in public safety type communications, where the end user is expected to remain focused on the public safety task at hand without distraction. 
     The data storage memory  104  receives and stores the customer order (referred to herein as the order) from the ordering system  102 . The service management system  106  comprises a service management controller for processing the order stored in memory  104 . The service management system  106 , bearer management system  108 , and the device/gateway management system  112  may be formed for example, of one or more local servers, distributed servers, and/or cloud based solutions, to name a few. 
     In accordance with some embodiments, the service management controller  106  analyzes the order and establishes the services comprising the features, bearer providers, and capabilities with which to provision the plurality of mobile communication devices  116  and configure the gateways  118  in response to the order comprising at least one or more of a device based subscription and/or user based subscription. For example, some order entry features may require the use of a particular bearer provider, and that bearer provider may need to be verified as having capacity to handle a particular number of devices with the requested features. As an additional example, some order entry features may require the use of an application gateway, and that application gateway may need to be verified as having capacity to process the data associated with the requested features. The service management system  106  provides the flexibility to determine that some features, such as a location feature (e.g. GPS), may be suited as a user based subscription for some customers, while better suited as a device based feature for other customers. 
     In accordance with some embodiments, the device/gateway management system  112  comprises a device management controller configured by the service management controller for provisioning and deploying the plurality of mobile communication devices  116 , over the communications network  114  via one or more gateways  118 . The gateways  118  may comprise application gateways configured for cloud-based access to the network  114  and/or access gateway configured for as land-based servers wired to the network  114 . The configuration of gateway is determined by the service management system and configured by the device/gateway management system. The configuration of devices  116  and gateways  118  are stored in and can be retrieved from a data storage unit  113  associated with the device/gateway management system  112 . 
     In accordance with some embodiments, the plurality of mobile communication devices  116  are deployed as converged devices, having at least one feature operable over narrowband LMR and at least one feature operable over broadband. The plurality of mobile communication devices  116  thus operate in accordance with the established features, established bearer providers, and established capabilities associated with their subscription orders. The billing service  120  automatically generates billing based on subscription order entries stored in the memory  104 , wherein the billing is adjusted based on the type of features ordered, the type of bearer provider provided, and the capabilities of the bearer provider to handle the feature associated with the order entry. Changes to billing are automatically generated in response to subscription updates which may occur via order entry or in the field as a result of a predetermined trigger. Such triggers may occur as a result of an unforeseen event negatively impacting LMR narrowband operations, thereby necessitating a need to transition certain features and bearer providers to alternative features and bearer providers, over broadband frequency operation. For example, a PTT feature normally operating over LMR bearer provider may be automatically transitioned to a backup PTT feature over LTE bearer provider or a backup PTT over WiFi bearer provider, in the event that the LMR system has been negatively impacted by an event. When the LMR bearer provider becomes operational then the reverse transition can take place. The billing does not necessarily always require a fee, for example a customer may be provided with free access to alternative features or bearer providers for a predetermined time. Again, the selection of which alternative bearer provider for a particular feature is based on customer parameter needs, such as quality of service. For example, backup PTT over WiFi might be free (no fee) while backup PTT over LTE might have a fee (due to the higher quality of service typically associated with LTE as compared to WiFi). Hence, in accordance with some embodiments, the communication system is configured such that at least one subscription service is operable over narrowband LMR and at least one subscription service is operable over broadband, wherein the at least one subscription service operable over narrowband LMR is further configured for automatic transition to an alternative subscription service over broadband in response to a trigger indicative of the LMR narrowband becoming unavailable. 
     As mentioned previously, device based subscriptions are those which may be provisioned to an entire fleet of mobile communication devices. For example, a back-up PTT feature, device programming feature, additional over the air protocols and others known or yet to be developed. Device based subscriptions can be configured for pooled devices (shared by many users over different shifts) and thus all such provisioned devices will have access to those device based features. Device based subscriptions are particularly advantageous for mission critical type radio functions. Additionally, in accordance with the converged device operation of devices  116  within the communication system  100 , the device based subscriptions can be used to provision mission critical services (and features within those services) with transferability capability from a primary narrowband LMR public safety bearer to an alternative broadband bearer, such as LTE, WiFi, Bluetooth, or 5G cellular to name a few. Billing by the billing service  120  of device based subscriptions is determined upon deployment and subsequently updated in response to device based subscription updates, changes/transfers or cancellations. 
     As mentioned previously, user based subscriptions are those which provide access and/or limit access to ordered services (and features within those services), to particular identified individuals as determined by the customer order. For example, user based subscriptions may comprise features such as a virtual assistant feature, location over broadband application, computer aided dispatch, messaging over broadband, video access and streaming and others known or yet to be developed. For example, the customer order may permit access to a feature to particular identified senior officer/users but not permitted access to the feature to lower ranked officers. Additionally, in accordance with the converged device operation of devices  116  within the communication system  100 , the user based subscriptions can be used to provision mission critical features (such as computer aided dispatch or messaging) with transferability capability from a primary narrowband LMR public safety bearer to an alternative broadband bearer, such as LTE, WiFi, Bluetooth, or 5G cellular to name a few. Billing by the billing service  120  of user based subscriptions is determined upon deployment and subsequently updated in response to user based subscription updates, changes/transfers or cancellations. 
     Subscriptions, whether device based or user based, are actively managed by the service management system  106  to provide assignment of bearer providers  110 , via bearer management system  108 , based on different bearer provider capabilities and availability within the communication system  100 . Capabilities associated with bearer providers  110  may include but are not be limited to, quality of service (QoS) of a current and alternative bearer provider, availability of a current and alternative bearer provider, duration of time anticipated for use of the current and alternative bearer provider, number of calls to be processed by the current and alternative bearer provider, data rate of the current and alternative bearer provider, and time duration of calls processed through the current and alternative bearer provider, to name a few. The billing service  120  is automatically updated based on initial subscription order, additional subscription order, renewal of a subscription order, cancellation of a subscription order, and transfer of a subscription service from one bearer provider to the alternative bearer provider which automatically adjusts the subscription order accordingly. The billing service  120  may also perform audits to ensure appropriate billing for the subscriptions services. Hence, the billing service  120  is responsive to dynamic changes that may take place within the communication system  100 . 
     Hence, the service management controller of service management system selectively provisions the plurality of mobile communication devices  116 , via the device gateway management system  112 , to operate certain subscription services over a public safety, LMR narrowband bearer provider and other subscription services over a broadband bearer provider in response to various subscription orders. It is extremely advantageous that mission critical functionality be maintained for all devices within a fleet, particularly in the event that the LMR narrowband system (the primary system) becomes negatively impacted by some unforeseen event. The service management system  106  advantageously manages the selection of current and alternative bearer provider(s), via bearer management system  108 , that can handle such mission critical features based on the aforementioned bearer provider capabilities. Once bearer providers are selected for those mission critical features, the service management system  106  configures the device/gateway management system  112  to provision the devices  116  and/or configure the gateways  114  accordingly. Again, the subscription based deployment and management advantageously remain transparent to a customer as well as the end user utilizing the managed device and managed gateways. 
       FIG. 2  is an example table  200  summarizing subscription features for the communication system  100  of  FIG. 1  in accordance with some embodiments. Referring to both  FIGS. 1 and 2 , able  200  is used to illustrate the flexibility of the service management system  106  controlling, via its service management controller, the subscription based deployment and management of mobile communication devices  116  within the communication system  100 . 
     Column  202  identifies an incoming service subscription order including a feature request, wherein the feature request is one of a device based feature and/or a user based feature. Columns  204  identify feature association as being device specific or user specific. For example, device specific features may comprise, device programming, provisioning management, such as fleet provisioning, back-up PTT, and additional communication protocols, and other device specific features known or yet to be developed. 
     Referring again to column  204 , features associated with a particular user which leverage user context, user specific preferences, or multi-device available are deemed to be user-specific features. For example, user specific features may comprise a virtual assistant, messaging, and location (GPS) and others known or yet to be developed. 
     At columns  206 , the subscription may be part of a new device order, a request to add a new feature to an existing device in the field, or a request to renew an already existing feature subscription which is about to expire or has expired, thereby providing for a very flexible subscription process managed by the service management controller  106 . Such orders may be dependent on the device, where a customer associates with the device, for example individual issued device, location deployed device, or device associated with a purpose designed vehicle. Or, the order may be independent of the device, where the customer associates with a user, for example supervisor with clearance for computer aided dispatch assignments, investigator with a role requirement for messaging, and role assignment requirements. For the purposes of this application the customer and the user are considered different entities. For example, a customer may be a county Sheriff&#39;s Department, and field user(s) may be particular sheriff officers within that sheriff department, identified, for example, by rank or position (e.g. Chief of Police, detective, etc.) or name (e.g. Sheriff Deputy John Doe). 
     Column  208  shows that the subscriptions, whether device based or user based, may have a criteria based expiration associated therewith. Subscription lengths can be bound by associated expirations having different measurements including time duration, termination date, data usage, cycle usage, and additional measurable parameters. The subscriptions may be, for example time-bound, for example one to two years, and are non-transferable to other non-subscribing devices. 
     Table 2 illustrates the flexibility in the management of subscription processing. For example, service management system  106 , via its service management controller, may operate using predetermined criteria, such as which bearer provider  110  has been identified as having capacity to provide a requested feature. Predetermined quality of service levels may be offered by certain bearer providers for certain features. For example, a subscription offering may comprise a feature at two different price levels, wherein the higher priced feature is provided by an LTE bearer operating at a higher quality of service level than, for example, that same feature being offered by a less costly bearer provider, such as Wi-Fi with a lower quality of service level. The service management system  106  automatically manages the selection of bearer provider based on the customers&#39; requirements as determined by the customer order. The service management is seamless to the end user of the ultimately deployed and maintained device. 
     Subsequent to deployment, devices  116  may be reconfigured or updated based on predetermined triggers, such as in the event that the LMR narrowband system (the primary system) becomes negatively impacted by some unforeseen event. Such updates may be approved or denied based on parameters set by the initial customer order. Thus, only features which are deployed are usable and charged a subscription fee. Additional or reconfigured features may happen in the field, in response to event triggers, such as loss of LMR bearer provider. In such an example, the customer can order additional Back up PTT feature for fielded devices, the service management system  106  will verify capacity to authorize the new subscription request. The service management system  116  determines if the request can be granted and subscription adjusted accordingly for the new feature and cost associated therewith. Thus, a mobile communication device in the field can be updated with a new feature if the device, available gateway, and available bearers have the ability to support the new addition. If such provisioning is not available due to access, application, or bearer capabilities, then the service management controller evaluates the subscription offerings and evaluates the changes to the subscription for this new request. If approved, the service management controller reconfigures access, application, bearer, and device with the updated feature in the field. 
     The ability for a customer to save cost for an across the board offering is highly advantageous. For example, LTE service may only be activated in devices with subscriptions that include features that require LTE bearer support. The ability to provide automatic service transitions triggered by an unforeseen event may be offered, deployed, and managed for free, lower fees, or higher fees for the duration of the event, or for some other predetermined amount of time. For example, fees for PTT over LMR can be adjusted when transitioned to backup PTT over LTE. 
       FIG. 3  is block diagram of subscription offerings along with example features and example transport for those features as provided by the subscription based communication system  100  of  FIG. 1  in accordance with some embodiments. Referring to both  FIGS. 1 and 3 , the subscription offerings may be device subscription offerings  302  and/or user subscription offerings  304 . The device subscription offerings  302  and user subscription offerings  304  provide for a plurality selectable features  320  tailored for that customer&#39;s requirements, and from which the customer may order. Appropriate transport  330  for each selectable feature  320  is provisioned based the capabilities associated with devices and bearer providers within the communication system  100 , as managed by the controller of service management system  106 . Capabilities associated with bearer providers may include but are not be limited to, quality of service (QoS), bearer availability, anticipated duration of time for use of the feature, data rate of bearer provider, to name a few. 
     Device subscription offerings  302  provide a plurality of selectable features associated with a device, such as a backup PTT feature  306 , a device management feature  308 , and others known or yet to be developed. User subscription offerings  304  provide a plurality of selectable features, such as  310  and virtual assistant  312 , and others known or yet to be developed. 
     The subscription offerings  302 ,  304  offered for sale define features, bearer type, and capabilities needed for the device and gateway. As mentioned earlier, the bearer type, and capabilities advantageously remain transparent to the customer and the end user. The service management controller of service management system  106  of  FIG. 1  provisions the devices  116  and configures the gateways  118 , based on the features, bearer providers, and capabilities and may further enable new gateways and bearer services, if needed, based upon availability and capability requirements. As an example, a device subscription offering  302  of backup PTT feature  306  enables a device to automatically communicate via a specific protocol over a broadband bearer in the field in response to a trigger event, such as loss of LMR, thereby transferring the transport of mission critical features, from an LMR bearer provider to alternative transport system, such as WiFi  316  or LTE  318 . Devices enabled with backup PTT over, for example, WiFi will only pay for subscriptions rates for the WiFi service, while those systems or devices operating backup PTT over LTE will pay for subscriptions at a higher subscription rate due to the higher quality of service. 
     As another example, a user subscription offering  304  of a location feature  310  and virtual assistant feature  312  may be transported over narrowband LMR or over a broadband transport system, such as LTE or WiFi, or other transport system. The service management system  106  provides the flexibility to determine that some features, such as a location feature (e.g. GPS), may be suited as a user based subscription offering  304  for some customers, while better suited as a device based subscription offering  302  for other customers. As part of the user subscription offerings  304 , the location feature  310  and/or virtual assistant feature  312  is/are configurable for capable devices over selected bearer providers. For example, a virtual assistant feature may be operated on some devices over LTE, while the virtual assistant feature may be operated on a different device over WiFi, the devices being within the same communication system  100 . Hence, user subscriptions can be tailored for individuals requiring different levels of service within a given feature. For example, senior ranking officers or officers identified by name may have devices configured with voice and data location services, operating over LTE, while other police officers, within the same department, may only require data location services, configured over WiFi. Remote support from the service management system  106  may be offered for acceptable LTE and/or WiFi or other non-LMR transports. Users with a single device enabled with, for example, virtual assistant will only pay a specific subscription rate, while users with multiple features will pay for subscriptions at a higher subscription rate due to the higher capacity of service. 
       FIG. 4  is a flowchart of a method  400  for deploying and managing a communication system formed and operating in accordance with some embodiments. At least one of: a device management update  402 , a new service request  404  and/or a service update request  406  is/are entered into the order system  102  of  FIG. 1 . Referring to both  FIGS. 1 and 4 , in response to the entry, registration takes place at  408 , by the service management controller of service management  106 , where one or more device(s) and/or suitable gateway(s) register with the service management system  106 . For example, for a new device being deployed  402 , the service management system, at  408 , registers the device and registers one or more gateways (wired access gateway and/or cloud based applications gateway), suitable for the new device and requested features or services associated with that new device. As another example, requests for new service(s) offerings  404  to be added to the order system causes the management system to register, at  408 , one or more gateways (wired access gateway and/or cloud based applications gateway) suitable for transport of the new service offering. As another example, for a service update  406  to an already deployed device, the service management system registers, at  408 , one or more gateways (wired access gateway and/or cloud based applications gateway) suitable for updating a feature to the already deployed device. 
     Subsequent to registration at  408 , verification is made at  410  by the controller of service management system  106  as to the status of available services. Service management system  106  is used to manage services which comprise features, bearer providers, and capabilities within communication system  100 . 
     A check is made at  412 , to determine if any change to service has been triggered. If no change in service has been triggered at  412 , then current service is retained at  416 . Adjustment to subscription takes place at  414 , in response to the service management system informing the billing service of changes in services. Triggers that may result in a change of service may comprise for example a change in one or more of features, bearers, and/or capabilities associated with the communication system  100 . 
     A ‘feature trigger’ causing a change in service may be, for example, a request to update the configuration of at least one device within the communication system with one or more features (or the removal of one or more features), such as back-up PTT, device management, location services, and/or virtual assistant services, as well as different provisioning within those features, such as location services being changed for voice and data, voice only, and/or data only. 
     A ‘bearer provider trigger’ causing a change in service may occur, for example, as a result of a bearer provider becoming unavailable triggering transfer to another bearer provider. For example, an LMR bearer provider becoming unavailable results in the transfer of one or more mission critical functions of a device to an alternative bearer provider for transport, such as LTE or WiFi. 
     A ‘capability trigger’ causing a change in service may occur, for example, as a result of a change in capabilities that impact a feature and/or bearer provider. For example, a bearer provider lacking the capacity to handle a new feature associated with a new order or update, or lacking capacity to handle a new device, may trigger a change in service, such as a transferring to a new bearer provider. 
     If a service change has been triggered at  412 , then adjustment to subscriptions are made at  414  followed by the update to the device and/or reconfiguration of the gateways (wired access gateway and/or cloud based applications gateway) at  418 . These updates may include changes to features, bearers, and/or capabilities. Adjustments to the billing service are made at  420  in accordance with the adjusted subscription at  422 . 
     New feature, bearer, and/or capability is/are then enabled at  422 . Accordingly, the service management system operates as a hub to facilitate the deployment of devices, as well as the subsequent management of those devices within a communication system  100 . 
       FIG. 5  is sequence diagram  500  for the communication system of  FIG. 1  formed and operating in accordance with some embodiments. Referring to both  FIGS. 1 and 5 , the sequence diagram  500  is described in terms of an ordering system  502  (similar to order system  102 ), a data storage unit  504  (similar to data storage unit  104 ), a bearer management system  506  (similar bearer management system  108 ), a service management system  508  (similar to service management system  106 ), a device/gateway management system  510  (similar to device/gateway management system  112 ), one or more gateways  512  (similar to the one or more gateways  118 ), and one or more devices  514  (similar to the one or more devices  116  of  FIG. 1 ). Another data storage unit, not shown but similar to data storage unit  113  of  FIG. 1 , is understood to be associated with the device/gateway management system  510 . Service deployment  516  is illustrated in the upper portion of the sequence diagram  500 , and service management  518  is illustrated in the lower portion of the sequence diagram. 
     Deployment 
     Starting at order system  502 , a service order  520  comes in from customer and gets stored in data storage unit  504 . A new service request is generated at  522 , based upon the subscription offering (similar to subscription offerings  103 ). The service management system  508  takes the service request and generates new device/gateway configuration information at  524  which is provided to the device gateway management system  510 . The device gateway management system  510  provides gateway provisioning at  526  and device provision at  528 . An alert is sent to the service management system  508  when provisioning is completed at  530 . The service management system  508  initiates bearer configuration at  532 , and acknowledgement at  534  of the configuration from the bearer management system  506  back to service management system  508 . The service management system  508  then updates the data storage  504  with the resultant of verification at  536 . 
     Management 
     Once devices and gateways have been deployed, the service management system  508  begins monitoring and managing the communication system, as there may be a need to update or change an existing service. The service management system  508  sends out a verification request at  538  to the device/gateway management system  510 . The device/gateway management system  510  determines current status  540  from its associated storage unit (not shown). At  542 , the device/gateway management system  510  notifies at  542  the service management system  508  with the verification status. 
     The service management system  508  identifies the needed configuration updates or changes and transmits those configuration updates or changes to the device/gateway management system at  544 . The gateway side of device/gateway management system  510  updates the gateway provisioning details and notifies the service management system  508  and gateway  512  of gateway updates at  546 . The device side of device/gateway management system  510  updates the device provisioning details and notifies the service management system  508  and device  514  of the device updates at  548 . 
     The service management system  508  identifies configuration updates or changes to the gateway and/or device and transmits those configuration changes or updates to the bearer management system at  550 . The bearer management system notifies the service management system  508  of updates or changes at  552 . The service management system  508  then updates the data storage  504  with service management updates associated with updates or changes made to any of the device, gateway, and bearer at  554 . 
     In the sequencing diagram  500 , verification of the bearer is advantageously not required because that service is already being paid for (already part of the billing) as it is not a shared element. Any changes to the bearer will be reflected in the data store  504  based on preexisting orders. 
     Accordingly, there has been provided a system and method of subscription based deployment and management of a communication system. The subscription offerings are advantageously configured for optimized services for public safety customers upon deployment and billed accordingly. The subscription services deployed to mobile communication devices and gateways are further beneficially updatable in the field, and subscription billing adjusted accordingly, while remaining transparent to the public safety end user. The management and control of subscription services by the service management system facilitates the convergence of narrowband public safety communications and broadband communications in a mobile communication device as well as fleet management of those devices a part of a communication system, even under varying changes to operating conditions within the system, such as an unforeseen event impacting operation of mission critical services triggering a change to an alternative service provider for predetermined mission critical features. 
     In the foregoing specification, specific embodiments have been described. However, one of ordinary skill in the art appreciates that various modifications and changes can be made without departing from the scope of the invention as set forth in the claims below. Accordingly, the specification and figures are to be regarded in an illustrative rather than a restrictive sense, and all such modifications are intended to be included within the scope of present teachings. 
     The benefits, advantages, solutions to problems, and any element(s) that may cause any benefit, advantage, or solution to occur or become more pronounced are not to be construed as a critical, required, or essential features or elements of any or all the claims. The invention is defined solely by the appended claims including any amendments made during the pendency of this application and all equivalents of those claims as issued. 
     Moreover in this document, relational terms such as first and second, top and bottom, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. The terms “comprises,” “comprising,” “has”, “having,” “includes”, “including,” “contains”, “containing” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises, has, includes, contains a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by “comprises . . . a”, “has . . . a”, “includes . . . a”, “contains . . . a” does not, without more constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises, has, includes, contains the element. The terms “a” and “an” are defined as one or more unless explicitly stated otherwise herein. The terms “substantially”, “essentially”, “approximately”, “about” or any other version thereof, are defined as being close to as understood by one of ordinary skill in the art, and in one non-limiting embodiment the term is defined to be within 10%, in another embodiment within 5%, in another embodiment within 1% and in another embodiment within 0.5%. The term “coupled” as used herein is defined as connected, although not necessarily directly and not necessarily mechanically. A device or structure that is “configured” in a certain way is configured in at least that way, but may also be configured in ways that are not listed. 
     It will be appreciated that some embodiments may be comprised of one or more generic or specialized processors (or “processing devices”) such as microprocessors, digital signal processors, customized processors and field programmable gate arrays (FPGAs) and unique stored program instructions (including both software and firmware) that control the one or more processors to implement, in conjunction with certain non-processor circuits, some, most, or all of the functions of the method and/or apparatus described herein. Alternatively, some or all functions could be implemented by a state machine that has no stored program instructions, or in one or more application specific integrated circuits (ASICs), in which each function or some combinations of certain of the functions are implemented as custom logic. Of course, a combination of the two approaches could be used. 
     Moreover, an embodiment can be implemented as a computer-readable storage medium having computer readable code stored thereon for programming a computer (e.g., comprising a processor) to perform a method as described and claimed herein. Examples of such computer-readable storage mediums include, but are not limited to, a hard disk, a CD-ROM, an optical storage device, a magnetic storage device, a ROM (Read Only Memory), a PROM (Programmable Read Only Memory), an EPROM (Erasable Programmable Read Only Memory), an EEPROM (Electrically Erasable Programmable Read Only Memory) and a Flash memory. Further, it is expected that one of ordinary skill, notwithstanding possibly significant effort and many design choices motivated by, for example, available time, current technology, and economic considerations, when guided by the concepts and principles disclosed herein will be readily capable of generating such software instructions and programs and ICs with minimal experimentation. 
     The Abstract of the Disclosure is provided to allow the reader to quickly ascertain the nature of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. In addition, in the foregoing Detailed Description, it can be seen that various features are grouped together in various embodiments for the purpose of streamlining the disclosure. This method of disclosure is not to be interpreted as reflecting an intention that the claimed embodiments require more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive subject matter lies in less than all features of a single disclosed embodiment. Thus the following claims are hereby incorporated into the Detailed Description, with each claim standing on its own as a separately claimed subject matter.
