## Title
Service management system that enables subscriber-driven changes to service plans

## Abstract

A service management system that enables a subscriber of a mobile telecommunication system to modify aspects of his or her service plan and have the modification to the service plan take effect immediately. The subscriber enters a modification request to an aspect of a service plan. The modification request is verified against a set of rules that defines acceptable changes to the service plan. If the proposed modification to the service plan is a valid change, the change to the service plan is immediately propagated to a billing system and to other systems that implement the service plan. The subscriber is notified when the modification to the service plan is complete, and the subscriber is billed on a going-forward basis in accordance with the rate structure applicable to the plan.

## Background
TECHNICAL FIELD
The present invention relates to managing service plans in mobile telecommunication systems.
BACKGROUND
Most consumers who use mobile telecommunication devices rarely change aspects of their service plan with their mobile service provider. This rarity may be attributed to the time and effort required to effect the service plan change. To make a change, a subscriber must typically initiate contact with the service provider via a telephone call to customer service or via a self-help system on the service provider's website. Once contact is initiated, implementing a change can be a multi-step process that takes a certain amount of time to complete and a certain understanding of all of the service plan options to make an informed decision. While most service providers strive to simplify this process, the change process may sometimes discourage subscribers from making a change to their service on a frequent basis.
Even if a service provider simplifies the process of changing aspects of a subscriber's service plan, the process is often not performed in a subscriber-friendly fashion. Changes are rarely implemented immediately, and may take twenty-four (24) hours or more to propagate through the service provider's systems. While most consumers are willing to accept this delay, the lack of immediate feedback to the consumer is a sub-optimal experience. Most consumers would prefer a service provider that reduces the time and effort necessary to change a service plan, such as by eliminating the need to personally contact the service provider. Most consumers would also prefer a service provider that completed a requested change immediately. If such an offering existed, it is expected that subscribers would more frequently make changes to their service plan and would ultimately be more satisfied with the service that they receive.

DETAILED DESCRIPTION
A service management system is disclosed that enables a subscriber of a mobile telecommunication system to modify aspects of his or her service plan and have the modification to the service plan take effect immediately. The subscriber effects changes to his or her service plan via a mobile device interface or via a non-mobile computer interface. The subscriber directly enters a modification to an aspect of the plan. The subscriber's proposed modification is verified against a set of rules that defines acceptable changes to the service plan. If the proposed modification to the service plan is a valid change, the change is immediately propagated to a billing system and to other systems that implement the service plan. The subscriber is notified when the modification to the service plan is complete, and the subscriber is billed on a going-forward basis in accordance with the rate structure applicable to the plan. Subscribers benefit under the system because changes are easily made by the subscriber and implemented in a timely fashion. As a result, overall subscriber satisfaction with the service provider is enhanced.
In some embodiments of the system, the provider's service plan allows subscribers to create a contact group containing a limited number of people or services. Communications to and/or from the people or services in the contact group are billed at a reduced rate (e.g., all communications are free, all communications are billed at a fixed monthly fee, all communications are billed at a reduced rate). The subscriber is allowed to periodically change the members of the contact group, with the service plan's billing scheme being applied to the new members in the contact group as soon as any change is made. Certain rules are applied to the composition of the contact group, including the allowed frequency of updates to the group, thereby constraining some of the modifications that the subscriber can make to the group. Any modifications to the service plan proposed by the subscriber are therefore verified by the service management system against a set of rules that characterize acceptable changes before being implemented.
The terminology used in the description presented below is intended to be interpreted in its broadest reasonable manner, even though it is being used in conjunction with a detailed description of certain specific embodiments of the invention. Certain terms may even be emphasized below; however, any terminology intended to be interpreted in any restricted manner will be overtly and specifically defined as such in this Detailed Description section.
Various embodiments of the invention will now be described. The following description provides specific details for a thorough understanding and enabling description of these embodiments. One skilled in the art will understand, however, that the invention may be practiced without many of these details. Additionally, some well-known structures or functions may not be shown or described in detail, so as to avoid unnecessarily obscuring the relevant description of the various embodiments.
FIG. 1 is a block diagram illustrating some of the components of a mobile telecommunication system 100 that includes a service management system 110 that allows subscribers to manage aspects of a service plan offered by a service provider in substantially real-time. The service management system 110 acts as an intermediary between a population of subscribers using mobile devices 120, a billing system 130, and a communication network 140 that enable the subscribers to receive mobile telecommunications services in exchange for a fee. Mobile devices 120 may include mobile phones, mobile personal digital assistants (e.g., Palms, PocketPCs, Blackberries or Treos), or any other mobile device having a service plan. The mobile devices 120 may each contain a service client 180 that in conjunction with the service management system 110 allows a subscriber to manage aspects of his or her service plan.
For purposes of this description, a group-centric service plan is used as a representative service plan managed by the subscriber. In a group-centric plan, a subscriber is allowed to define a set of contact numbers in a contact group. A contact number can represent either a person or a service, for example, a service that receives emailed images and automatically prints the received image. Communications made between the subscriber and any of the contact numbers in the contact group are billed at a different rate than communications with contact numbers that are not in the contact group. For example, the subscriber may be billed at a flat rate for all communications with members in the contact group, at a discount for each communication with members in the group, or all communications with members in the group might be free. Alternatively, communications made between the subscriber and any of the contact numbers in the contact group may be provided with preferential service or a feature that is not accessible to communications with contact numbers that are not in the contact group. For example, the subscriber may be provided with the ability to simultaneously broadcast the same message to members of his or her contact group, but not to members outside of his or her contact group. As another example, the subscriber may be provided with special ringtones for members of his or her contact group. In this context, “communication” means the transmission or receipt by the subscriber of any voice call, text, SMS message, instant message, email, picture, music, or any other data. The size of the contact group may vary significantly, but often the group contains twenty or less contact numbers. Moreover, members of the group can be associated with any telecommunication network, whether wired or wireless. That is, the contact numbers do not necessarily represent people or services that are serviced by the same mobile telecommunication system 100 as the subscriber. Additional information about a group-centric service plan is described in greater detail in U.S. patent application Ser. No. 11/400,925, entitled “Preferred Contact Group Centric Interface,” filed on 10 Apr. 2006, now U.S. Pat. No. 7,685,530, and incorporated in its entirety by this reference. While a group-centric service plan is used as a representative service plan throughout this description, it will be appreciated that the technology described herein is applicable to many other types of service plans as well. The described system is intended to apply to any service plan that would benefit from allowing a subscriber to make periodic modifications to the service plan, wherein the modifications are immediately implemented.
As shown in FIG. 1, the service management system 110 may communicate with mobile devices through a number of different communication paths. In the depicted embodiment, two communication paths are shown. The first path allows the mobile devices 120 to communicate with the service management system 110 through a WAP (Wireless Application Protocol) server 150. Those skilled in the art will appreciate that the WAP protocol enables mobile devices to access WAP-enabled websites and exchange information such as World Wide Web content using the hyper-text transfer protocol (HTTP). The second path allows the mobile devices 120 to communicate with the service management system 110 through a short message service (SMS) center 160. Those skilled in the art will appreciate that the SMS center stores and forwards SMS messages between the mobile devices and the service management system using the short messaging service peer-to-peer protocol (SMPP).
The service management system 110 also communicates with other components of the mobile telecommunications system 100 such as the billing system 130 and the communication network 140. The billing system 130 is an industry-standard billing system that bills for all communications made by a subscriber of a mobile device 120 during a billing period. The billing system includes a database 170 that maintains accurate and complete records of all billed uses of the telecommunication system 100 for each subscriber. The communication network 140 broadly encompasses all of the other systems in the telecommunication system that enables a mobile subscriber to have end-to-end connectivity with other people or services. The service management system 110 is also connected to the World Wide Web 190 as necessary to implement the functionality described herein. Those skilled in the art will appreciate that other standard systems and connections have been omitted from the mobile telecommunications system 100 for clarity.
Mobile devices 120 may include a service client 180 that uniquely identifies the subscriber and interfaces with the subscriber management system 110. The service client 180 maintains a record of certain subscriber-modifiable elements of the service plan. For example, in an embodiment wherein the service plan is a group-centric service plan, the service client 180 includes a table that identifies all of the contacts in a contact group. FIG. 2 is a representative service plan table 195 that is maintained by the service client 180. The table includes a number of fields that pertain to the service plan, including: a Mobile Subscriber ISDN Number field 200, which contains a number that uniquely identifies the subscriber to the service provider; an allowed contacts field 205, which contains a number that sets the size of (i.e., the number of contacts in) the contact group; and group contact fields 210a, 210b, . . . 210e. Each group contact fields 210a, 210b, . . . 210e identifies a contact by contact number and by subscriber-defined name. The contact number may be a phone number, an IP address, or any unique identifier that can be used to complete a communication with another person or service. The format of the contact number and subscriber-defined name may vary, but in an embodiment of the system seventeen digits are provided for the contact number and sixteen digits are provided for the subscriber-defined name. The service plan table 195 is maintained by the service client 180, and modifications to the service plan table are made in accordance with the process described below.
Prior to managing his or her service plan, a subscriber may first contact his or her service provider in order to activate the service plan. Contact with the service provider may be made in a variety of ways, including using the mobile device to send an SMS message to the provider or to visit a WAP webpage offered by the provider. Alternatively, the subscriber may contact the service provider by visiting the service provider's website using a laptop or desktop computer, by calling the service provider's customer service, or by visiting any of the service provider's retail stores and interacting with a sales person. After the service provider confirms that the subscriber is eligible to participate in the service plan, the service management system 110 and the service client 180 are each provisioned to configure the subscriber for service. In the case of the mobile device, the service management system 110 sends a command to the service client 180 turning the client “on.” At this point, the subscriber is allowed to begin managing aspects of his or her service plan and making modifications to certain aspects of the plan.
If the subscriber has activated a group-centric service plan, one of the aspects of the plan that the subscriber is allowed to manage is the composition of the contact group. When the service management system activates a group-centric plan it may populate all of the group contact fields 210a, 210b, . . . 210e in the service client 180 with zeros as an initial state, signifying that the subscriber has no contacts. After activation, the subscriber is allowed to populate the contact group with a desired group of people or services and manage the composition of the group over time. Information about the user interface that may be incorporated in the mobile device 120 to allow subscribers to modify the composition of their contact group is described in greater detail in the previously-referenced U.S. patent application entitled “Preferred Contact Group Centric Interface.” The subscriber is allowed to add new contacts into his or her contact group, change the contact number or contact name of existing contacts, and delete contacts from his or her contact group by making a modification request to the service management system 110. The modification request may be generated by the subscriber using the subscriber's mobile device (e.g., via an SMS message or WAP page) or by accessing the service provider's website using a non-mobile computing device. In an embodiment, the modification request is submitted to the service management system 110 in the following form:















[command] [position number] [contact number] [contact name]



    e.g., modify 02 4255551616 Alice










Where [command] is the desired command, [position number] is the numerical position of the contact within the contact group that is to be modified, and [contact number] and [contact name] are the contact details entered by the subscriber. In the example modification request made above, the subscriber is requesting that the second contact (position 02) in the contact group be modified so that the contact number is “425-555-1616” and the name is “Alice.” In an embodiment of the system, the command field is a two digit code, with each combination of digits representing a different command (e.g., modify=“01”). Various other commands may therefore be supported by the system, as will be described in additional detail below.

FIG. 3 is a block diagram illustrating the various components of the service management system 110 that receives the modification request and allows a subscriber to change an aspect of his or her service plan so that the changes are immediately implemented and reflected in how the subscriber is billed. As will be described in greater detail below, the service management system includes a service rule set 220 that defines those conditions under which the subscribers may modify their service plan. The service management system includes a subscriber database 215 that contains details about subscriber service plans, including those aspects of the service plan that may be manipulated by a subscriber. When the service plan is the group-centric plan described above, the subscriber database stores the identity of the people or services contained in the subscriber's contact group. FIG. 4 is a representative table 300 of the type of information that may be stored in the database for a group-centric plan.
As depicted in FIG. 4, each record 310 in the table 300 represents one subscriber and the identity of all contacts that the subscriber maintains in his or her contact group. Each record 310 contains a number of fields, including: a Mobile Subscriber ISDN Number field 320, a time stamp field 330, an allowed contacts field 340, an account type field 350, and a number of group contact fields 360a, 360b, . . . 360n. The Mobile Subscriber ISDN Number field 320 contains a number that uniquely identifies the subscriber for the service provider. In the sample record 370, the number is the 15 digit code “968375100064721.” The time stamp field 330 contains a timestamp that indicates when the subscriber was first provisioned with the service plan. The allowed contacts field 340 contains a number that is set by the service provider to reflect the maximum number of contacts that the subscriber may have in his or her contact group. In the sample record 370, the number of contacts is set for five. The account type field 350 contains a code number reflecting the type of account that the subscriber maintains with the service provider. For each person in a subscriber's contact group, the group contact fields 360a, 360b, . . . 360n contain a contact number 375, a subscriber-defined name 380 of the contact, and a service provider code 385. The contact number may be a phone number, an IP address, or any unique identifier that can be used to complete a communication with another person or service. The format of the contact number and subscriber-defined name may vary, but in an embodiment of the system seventeen digits are provided for the contact number and sixteen digits are provided for the subscriber-defined name. The service provider code is a code that identifies the service provider that the contact is associated with. As was previously described, the service plan may include communications between the subscriber and people or services in other service networks, so the service provider code is stored to both track the number of contacts that are in other networks as well as facilitate communication with those networks. It will be appreciated that the order of contacts in the database record 310 may correspond to the order of contacts in the display provided to the subscriber on the mobile device. For example, in record 370 the first contact is identified as “Uncle Scott” and the fifth contact is identified as “Mom.” These contacts would be displayed in the first and fifth locations, respectfully, on the mobile device. The contact numbers for Uncle Scott and Mom are provided, and it is noted that Uncle Scott and Mom use different service providers than the subscriber. When a subscriber first activates his or her service plan, the subscriber record 310 is populated with details of the service plan and zeros in all group contact fields 360a, 360b, . . . 360n. For example, record 390 represents a new subscriber that has recently activated the group-centric service plan. Record 395 represents a subscriber that has activated a group-centric service plan, but has not yet populated all of the contacts in the contact group as evidenced by the zeros in group contract field 360n. 
While FIGS. 2 and 4 depict a table whose contents and organization are designed to make them more comprehensible to the human reader, those skilled in the art will appreciate that the actual data structure(s) used by the system to store this information may differ from the tables shown, in that they, for example, may be organized in a different manner, may contain more or less information than shown, may be compressed and/or encrypted, and may be optimized in a variety of ways.
Returning to FIG. 3, when a modification request is received by the service management system 110 it is acted on in substantially real-time to either implement the modification request or to reject the modification request if it fails to satisfy the rules that govern allowed modifications. A process implemented by the service management system 110 to implement or reject the modification request is depicted in FIGS. 5A and 5B.
FIGS. 5A and 5B are flow charts that illustrate portions of a process 400 implemented by the service management system 110 to allow subscribers to manage an aspect of their service plan. The flow chart depicted in FIGS. 5A and 5B is suitable for a group-centric service plan, but may be modified as appropriate for other types of service plans. At a block 405, a request is received from a subscriber to modify one of the contacts in his or her contact group. As was previously discussed, the modification request is received in the following form: [command] [position number] [contact number] [contact name], where [command] is the command to modify, [position number] is the numerical position of the contact within the contact group that is to be modified, and [contact number] and [contact name] are the contact details entered by the subscriber. Note that the modify command can be used to represent a number of different subscriber requests such as adding a contact to the contact group, deleting a contact from the contact group, or changing the position number, contact number or contact name of a contact. For example, deleting a contact may involve inserting all zeros in the corresponding record. Those skilled in the art will appreciate that commands other than “modify” may also be used to manipulate entries within the contact group.
At a block 410, the service management system determines if the subscriber has activated the service plan that the subscriber is seeking to modify. If the subscriber has not activated the service plan, at a block 415 the subscriber is redirected to a service sign-up page. The service sign-up page may be communicated to the subscriber using an SMS message, web-page redirect, or by other contact method. After redirecting the subscriber, the process terminates pending the subscriber activating the service.
If the subscriber has activated the service plan that he or she is seeking to modify, at a decision block 420 the service management system determines whether the modification request entails only a name change. Modification requests that entail only a name change may be processed with less scrutiny by the system, as the decision of what name to associate with a contact number in the service plan is entirely within the discretion of the subscriber. One way to determine if only a name change has been requested is to compare the request with the associated subscriber record in the subscriber database 215. If only a name change is required, at a block 425 the service management system sends a command updating the name to the service client 180 in the subscriber's mobile device 120. The service management system also updates the subscriber record in the subscriber database 215 to reflect the new name for the identified contact. It will be appreciated that the definitive record of the subscriber's contact group is maintained in the subscriber database 215 by the service management system 110, and that any modifications to the record are made both locally in the service management system 110 and remotely at the subscriber's mobile device 120. At a block 430, the service management system sends a message to the subscriber confirming that the modification request has been completed. Once the modification request has been acted on, processing of the request is complete.
If the modification request entails more than a change to a contact name, processing continues to decision block 435. At decision block 435, the service management system performs a test to determine whether the received contact number in the modification request is a valid contact number. Different rules may be applied to determine that a contact number is valid, but in an embodiment of the system a contact number is considered to be valid if it falls within a certain geography (e.g., within the continental United States) and does not fall on the list of certain numbers that should be excluded (e.g., due to past problems with fraud on an excluded number). If the contact number is found not to be a valid number, at a block 440 the service management system sends a command to the service client 180 rejecting the modification request. When the service client 180 receives the command rejecting the request, the modification request is discarded and no changes are made to the contact group maintained in the service client 180. At a block 445, the service management system sends a message to the subscriber indicating that the entered contact number is not a valid number and that processing of the modification request has been halted. An option may be given to the subscriber to re-enter or otherwise correct the contact number. If such an option is provided, processing of the modification request would begin again at block 405.
If the contact number is found to be a valid number at decision block 435, processing continues to a block 450. At block 450, one of a plurality of service rules may be applied to the modification request. Service rules are defined by the service provider to set limits on what actions a subscriber may take in changing aspects of his or her service plan. For example, in some embodiments of the system the service provider may set a rule that each contact in the contact group cannot be modified more than once a month or once every X days. In other embodiments, a rule may be set that a subscriber can only make a certain number of modifications a month (e.g., five). Subscribers may therefore decide whether to change one contact multiple times or multiple contacts one (or more) times. The service rules are stored in the service rule set 220, and accessed by the service management system 110. At a decision block 455, the service management system performs a test to determine whether the modification request satisfies the applied service rule. If the modification request satisfies the service rule, processing continues to a decision block 460 where the service management system determines whether there are additional service rules to apply. If additional rules need to be applied, processing returns to block 450 to apply the next service rule. If no additional rules need to be applied (and by implication, all previous service rules have been satisfied), processing continues to a block 475. It will be appreciated that the number of service rules is in the discretion of the service provider, and may range anywhere from zero (i.e., no rules are applied) to a large number of interdependent rules that would require more complex processing to determine whether they are satisfied.
If the modification request fails to satisfy any of the applied service rules at decision block 455, processing continues to a block 465. At block 465 the service management system sends a command to the service client 180 rejecting the modification request. When the service client 180 receives the command rejecting the request, the modification request is discarded and no changes are made to the contact group maintained in the service client 180. At a block 470, the service management system sends a message to the subscriber indicating that the modification request will not be made because the request failed to satisfy one of the service rules. Additional details about why the request failed may also be provided to the subscriber in the message. Once the modification request has been rejected, further processing is terminated.
Returning to block 475, the modification request may be acted upon since the modification request has satisfied all of the service rules and other tests. At block 475, the service management system 110 makes the appropriate modification to the subscriber database 215 by updating the contents of the subscriber's record. In the example modification request presented above, this would entail changing the second contact in the contact group to the contact number “425-555-1616” and the name “Alice.” At block 480, the service management system 110 sends a modification request to the billing system 130. Those skilled in the art will appreciate that the billing system maintains its own database 170 of subscribers and subscriber contact groups so that it may appropriately bill the subscriber for services used under that service plan. It is beneficial to update the billing system in substantially real-time as doing so enables ongoing reconciliation between the networks of different service providers. At a block 485, the service management system 110 waits to receive confirmation from the billing system that the modification has been made. When such confirmation is received, at a block 490, the service management system sends a command to the service client 180 directing the service client to implement the modification request. At a block 495, the service management system sends a message to the subscriber confirming that the modification request has been completed. Once the modification request has been acted on, processing of the request is complete.
Returning to FIG. 3, in addition to managing the proposed modification to the service plan by a subscriber, the service management system 110 may also manage other aspects of the activation, deactivation, and maintenance of a subscriber. As was previously mentioned, the service management system 110 may send an “on” command to the service client 180 to activate the client in anticipation of providing service. In addition to the “on” command, the service management system 110 may also send an “off” command to the service client 180 to deactivate the client. Deactivation may occur at the request of the subscriber, such as when the subscriber cancels a service, or may occur at the direction of the service provider when the subscriber fails to pay for a service or otherwise violates the terms of use of a service. The service management system 110 may also implement a “sync” command that is received from the service client 180. The sync command causes the service management system to copy the relevant contents from the subscriber's record 310 in the subscriber database 215 to the service plan table 195 maintained by the service client 180. The sync command may be used when a subscriber switches to a new mobile device or otherwise needs to update the contents of the entire contact group.
The service management system 110 also includes a number of components that allow the service provider to manage the system and allow the management system to communicate with the other portions of the telecommunication system. The service management system 110 includes interfaces 230, an alarm management and rollover control component 240, a reporting and analytics component 250, and an operating system component 260. The interfaces 230 are provided to allow the service management system 110 to communicate with other systems in the telecommunication system 100, such as the billing system 130 and the communication network 140. The interfaces may operate using a variety of standard protocols or defined APIs, such as SOAP or XML for communication with the billing system.
The alarm management and rollover control component 240 is included in the service management system 110 to maintain the overall reliability of the service management system. It will be appreciated that because modifications to subscriber service plans are intended to occur in a manner that is substantially in real-time, the service management system 110 is preferably a highly reliable service. In order to reach this goal, various technological solutions may be implemented. For example, the service management system may operate on a number of geographically-dispersed servers that are configured to be redundant. In the event that one of the servers fails, the other servers may take over the load without interruption of service. Alternatively, a standby server may be maintained that can be hot-swapped into the system in the event that a primary server fails. Those skilled in the art will appreciate that other solutions to maintain high reliability may be implemented by the alarm management and rollover control component 240.
The reporting and analytics component 250 allows the service provider that operates the service management system 110 to compile and review a number of reports that detail the health and operation of the system and the service plan. For example, when the service plan is a group-centric plan, the reporting and analytics component may produce reports such as the average number of subscribers, the average number of group modifications segmented in certain time periods (e.g., daily, weekly, monthly, yearly), the average number of group modifications rejected by the system, etc. Reports generated by the reporting and analytics component 250 allow the service provider to appropriately provision resources for the service management system, tailor the service plan based on the actual use of the subscriber base, and in general review system operation to ensure a high degree of subscriber satisfaction.
The operating system component 260 is one or more operating systems that create the environment for the operation of the software applications and database within the service management system. Those skilled in the art will appreciate that other standard components may be included in the service management system 110 in order to achieve the functionality described herein.
It will be appreciated that the system configuration disclosed herein significantly improves subscriber experience. Subscribers are able to modify aspects of his or her service plan in a variety of ways, and the modifications are quickly propagated throughout the telecommunication system so that the subscriber begins operating under the modified plan in a very short period (often in a few minutes or less). Billing integrity is maintained as changes are made to the billing system soon after the subscriber makes the modification request.
While various embodiments are described in terms of the environment described above, those skilled in the art will appreciate that various modifications can be made to the system without impacting the overall functionality. For example, while a service client 180 is maintained on the mobile device to ensure that the subscriber may view his or her group contacts even when not in range of a service network, a system could be envisioned that would only maintain the group contacts at a central server. A subscriber would access the central server to make modifications as described herein.
It will also be appreciated that the system may be implemented in a variety of environments. For example, the system could be implemented using a single monolithic computer system, a distributed system, or various other combination of computer systems or similar devices connected in a variety of ways. The system could be implemented using third-party services and data for all or portions of the aforementioned functionality. Moreover, as used herein, the term “database” should be interpreted to include any data structure that allows data to be stored and accessed, such as tables, linked lists, flat files, arrays, etc. Those skilled in the art will also appreciate that the steps shown in FIGS. 5A and 5B may be altered in a variety of ways. For example, the order of the steps may be rearranged, substeps may be performed in parallel, steps may be omitted, or other steps may be included.
Unless the context clearly requires otherwise, throughout the description and the claims, the words “comprise,” “comprising,” and the like are to be construed in an inclusive sense, as opposed to an exclusive or exhaustive sense; that is to say, in the sense of “including, but not limited to.” As used herein, the terms “connected,” “coupled,” or any variant thereof, means any connection or coupling, either direct or indirect, between two or more elements; the coupling of connection between the elements can be physical, logical, or a combination thereof.
