DETAILED DESCRIPTION

The present invention is directed toward networks and more particularly to a method and system for providing information related to billing in such networks.

The following description is presented to enable one of ordinary skill in the art to make and use the invention and is provided in the context of a patent application and its requirements. Various modifications to the preferred embodiments and the generic principles and features described herein will be readily apparent to those skilled in the art. Thus, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features described herein.

FIG. 1A illustrates a block diagram of a basic M2M network 100. The M2M network 100 comprises a circuit-switched voice network 193 that connects mobile handsets 192 with the public switched telephone network (PSTN) 110. Overlaid on top of the network is a packet-switched data network 194. Although circuit-switched SMS messages are used in M2M applications, increasingly M2M data is sent in packet format.

Base station controllers (BSCs) 114 control a number of base transceiver stations (BTSs) 116 that control the actual radio towers and interact with the handsets 192. Packet control units (PCUs) 114 transfer packets bound for the General Packet Radio Service (GPRS) network to a local service GPRS support node (SGSN) 102. Home location registers (HLRs) are a function on both the GSM and GPRS network, and essentially serves to identify mobile stations/end-points with specific account information. The SGSN establishes the packet data protocol (PDP) context with the Gateway GPRS support node (GGSN) 104. Upon activation packets bound for external networks (e.g., the Internet 108 or corporate private data networks (PDNs) 106) pass through the mobile packet gateway. Each mobile network gateway contains a number of virtual and physical access point nodes (APNs) 104 that define the specific external network, whether public or private, to which the packet is destined. GGSN 104 communicates with Authentication, Authorization and Accounting server (AAA) 120 to capture the accounting records for billing which are received by the billing system 122, for example, CDMA, 3GPP, 4G LTE and 5G.

Mobile packet gateways like GGSNs along with HLRs are two of the most critical network elements relative to M2M/IoT service deliver in the mobile network. Mobile packet gateways provide security, Quality of Service (QoS) enforcement, and interaction with charging and billing systems for mobile data service. Mobile packet gateways are also central to interconnecting the mobile infrastructure with 3rd-party networks, most importantly ASPs in the case of the M2M/IoT market. HLRs are critical to service creation and management of remote devices in the field.

FIGS. 1B and 1C illustrate billing system architectures 100′ and 100″ for 4G LTE and 5G networks respectively according to one or more embodiments of the present invention. It includes network elements and/or user equipment 192 (M2M machines and/or IoT devices) that provide billing data to a billing and analytics system 122 according to one or more embodiments of the present invention.

In case of 4G/LTE networks, as illustrated in FIG. 1B, Evolved Node B (eNB) 124 interacts with the handset/IoT Device 192 and transfer the packet data to Serving Gateway (S-GW) 126. S-GW 126 communicates with Packet Data Network Gateway (P-GW) 128 which is responsible for enforcing traffic policies and generating Charging Data Records (CDR) for accounting purpose. P-GW 128 retrieves the traffic policies from Policy and Charging Rules Function (PCRF) server 136.

Additionally or alternatively, the usage information for network devices 192 may come from AAA 120 for 4G LTE integration to the billing and analytics system 122.

Additionally or alternatively, in certain network core integrations, Traffic Control Function (TCF) 130, for example, Aeris Packet Function (APF), may be used for enforcing rules and routing the packet data to destination. TCF 130 in conjunction with Network Firewalls (FW) 132 may provide packet destination IP for each M2M/IoT Device 192. Destination IP details are then be ingested into Billing and analytics system 122 and used for adaptive billing/learning pricing plan.

Thus, the network elements interacting with network devices 192 that provide network device 192 usage data to the billing and analytics system 122 when using 4G LTE network include any one or more of: Packet Data Network Gateway (P-GW) 128, Traffic Control Function (TCF) 130, for example, Aeris Packet Function (APF), Authorization and Accounting server (AAA) and Network Firewall (FW) 132.

In case of 5G Network, as illustrated in FIG. 1C, Next Generation NodeB (gNB) interacts with the user equipment, for example, M2M or IoT device, and facilitates data communication. Access and Mobility Function (AMF) is a single-entry point for the handset/IoT device connection. AMF communicates with Authentication Server Function (AUSF) to authenticate the IoT device. Based on the needs of M2M/IoT device, AMF communicates to Session Management Function (SMF) to manage the IoT device session. AMF also interacts with other network functions like Policy Control Function (PCF) to manage policy rules, Unified Data Management (UDM) to obtain user identity and auth credentials. Once the IoT devices is authenticated and session is established, it can start sending data via User Plane Function (UPF). UPF communicates to Charging Function (CHF) which in turn provides Charging Data Records (CDRs) to billing system through Charging Gateway Function (CGF).

Additionally or alternatively, in certain network core integrations, Traffic Control Function (TCF), for example, Aeris Packet Function (APF), may be used for enforcing rules and routing the packet data to destination. TCF in conjunction with Network Firewalls (FW) may provide packet destination IP for each Handset/IoT Device. Destination IP details are then be ingested into Billing and analytics system and used for adaptive billing/learning pricing plan.

Thus, the network elements interacting with network devices 192 that provide network device 192 usage data to the billing and analytics system 122 when using 5G network include any one or more of: Charging Function (CHF), Traffic Control Function (TCF), for example, Aeris Packet Function (APF) and Network Firewall (FW).

As used herein the term M2M/IoT communication is understood to include methods of utilizing various connected computing devices, servers, clusters of servers, wired and/or wirelessly, which provide a networked infrastructure to deliver computing, processing and storage capacity as services where a user typically accesses.

FIG. 2 illustrates a conventional billing system architecture 200 utilized with M2M/IoT networks. The architecture 200 includes a network having network elements and network devices (NDx) (e.g. devices connected to the network such as M2M machines and/or IoT devices, for example, appliance, terminal, remote device, user equipment or wireless asset, machines, phones, communicators, etc.) 201A, 201B, 201C, a billing and administration system (BAS) 202, an invoice and reporting function 204, a customer function 206, an accounting and sales function 208, and a price plan system 210.

The BAS 202 provides for receiving data input from the NEs and also provides for calculating and determining billing and related administrative information for customer accounts in relation to the network devices being used on the associated network; the calculated billing and related administrative information is provided as input to the invoice and reporting function. The invoice and reporting function 204 provides for generating an invoice based on an arrangement between the network operator and the customer, typically in the form of a billing relating information about expenses arising from the NDs activity associated with the operator's network. Once input data is processed by the invoice and reporting function, billing details and routing of invoices, as one example, are then output to the customer function 206 in accordance with customer account details.

The customer function 206 provides for interaction with the customer and includes providing for arranging billing to the customer as well as receiving input from the customer (such as with discrepancies, account updates, device updates, other communications, etc.). Updates and requests from the customer function are input to the accounting and sales function 208. The accounting and sales function 208 may update, add, subtract and otherwise modify information associated with a customer's account, including device updates and billing plans, such that the BAS processing more accurately reflects the activities and administrative aspects of the customer account. The accounting and sales function 208 will output information to the Price Plan system including modifications to a customer's pricing plan and updated pricing plans available to the customer to better reflect a customer's needs. The Price Plan system 210 provides for information concerning the available billing, usage, device activity and associated network operations information concerning a customer's account. The pricing plans of a Price Plan system 210 may change from time to time to better reflect customer and market needs. The Price Plan system 210 outputs updates of the Price Plan as input to the BAS 202.

From FIG. 2, operatively, after receiving input of the NEs and the associated Price Plan system information, the BAS calculates a customer's bill based upon the price plan for the network devices, such as M2M machines and/or IoT devices, for example, appliance, terminal, remote device, user equipment or wireless asset. The calculated bill is output as input to the invoice and reporting function. The invoice and reporting function then generates invoices and routes the invoices to the customer, along with other reports as may be defined by the customer or operator. The customer receives the billings and reports via the customer function and may provide feedback or additional response, which when received is input to the accounting and sales function (e.g. accounting department) may then act in response to the customer feedback to adjust a billing, modify the account, adjust a price plan, and similar. Output from the accounting and sales function is processed by the Price Plan System to update pricing plan information which is then used by the BAS to calculate billings in a further activity.

It is desirable to be able to adjust the billing information before the accounting department receives the billing information and minimize the need for customer feedback. Furthermore, it is desirable to be able to adjust the billing information before the customer receives an invoice. Finally, it is desirable to be for the network to identify billing opportunities using the billing system architecture.

Accordingly, a system and method in accordance with an embodiment replaces the conventional billing system architecture a billing and analytics architecture. The billing and analytics architecture in accordance with an embodiment allows for a more accurate accounting of the revenues for an M2M/IoT network. Furthermore, such a system may minimize the need for customer feedback and concerns. Finally, such a system and method in accordance with an embodiment can be utilized to identify new billing opportunities in such a network. To describe the features of such a system refer now to the following description in conjunction with the accompanying Figures.

FIG. 3 is a block diagram of a billing and analytics architecture 300 in accordance with an embodiment. Usage information for customer's network elements also known as network devices ND1, ND2 and ND3, collectively shown as 301 (M2M machines and/or IoT devices, for example, appliance, terminal, remote device, user equipment or wireless asset) is provided to a billing system and analytics system 302 via network elements 314.

For example, the network elements 314 interacting with network device/s 301 that provide network device/s 301 usage data to the billing and analytics system 302 when using 4G LTE network include any one or more of: Packet Data Network Gateway (P-GW), Traffic Control Function (TCF), for example, Aeris Packet Function (APF), Authorization and Accounting server (AAA) and Network Firewall (FW) as illustrated in FIG. 1B.

Similarly, for example, the network elements 314 interacting with network device/s 301 that provide network device/s 301 usage data to the billing and analytics system 302 when using 5G network include any one or more of: Charging Function (CHF), Traffic Control Function (TCF), for example, Aeris Packet Function (APF) and Network Firewall (FW) as illustrated in FIG. 1C.

ND1-ND3, collectively shown as 301, could be any type of device, appliance, terminal, remote device, user equipment, or wireless asset, etc. are intended to be inclusive, interchangeable, and/or synonymous with one another and other similar communication-based equipment for purposes of the present invention though one will recognize that functionally each may have unique characteristics, functions and/or operations which may be specific to its individual capabilities and/or deployment.

The billing system and analytics system 302 provides invoices and reports 304. A price plan system 310 receives device usage information from the system 302 and provides a guaranteed price plan to the billing and analytics system 302 and initially provides a guaranteed price plan for the customer's network elements also known as network devices. Device usage includes bytes in, bytes out, device roaming status, destination IP from FWs etc. Billing and analytics system uses the bytes in, bytes out, roaming status and destination IP details to learn the pricing plan. For example, depending on the destination IP address and amount of bytes transferred, the learning system could learn/suggest specific pricing options for specific destination IP address. The devices may be grouped based on any one or more of: destination IP address, device roaming status for learning the price plan. Inputs to the price plan system are an initial price plan and a manual override of learned values. To describe the features of this system in more detail please refer now to the following discussion and the accompanying Figures.

FIG. 4 is a flow chart of the operation of the billing and analytics architecture 300 in accordance with an embodiment. In an embodiment, a process for adaptively determining a billing is provided. Referring to FIGS. 3 and 4 together, first an initial guaranteed price plan for a predetermined time period is provided to a customer, via step 402. Next, device usage over the predetermined time period is learned to provide a learned price plan, via step 404. The learned price plan can be for the whole account for a particular user, for a group of devices within the account, or for a learned pooling policy within the account. This allows for learning the price plan system and adaptively changing the price based upon usage. The new price plan is provided to the price plan system 310, via step 406. Finally, the new price plan is provided by the billing and analytics system 302 to be utilized with the customer's network elements, via step 408. This process can be repeated to ensure that the customer is getting the appropriate pricing for network element usage over the network.

In some instances, for example if the device usage fluctuates widely from one period to the next it may be desirable to rest from one system. Hence one of the inputs to the price plan system 310 is a manual override to the learned values such a learning process can begin again.

A billing and analytics architecture in accordance with an embodiment allows for a more accurate accounting of the revenues for an M2M/IoT network. Furthermore, such a system may minimize the need for customer feedback and concerns. Finally, such a system and method in accordance with an embodiment can be utilized to identify new billing opportunities in such a network.
