BACKGROUND
1. Field
The exemplary embodiments and methods described herein relate to cellular connectivity for a franking machine.
2. Brief Description of Related Developments
Mailing machines enable users to frank one or more mail items by printing a stamp representing the amount paid by the sender. For example, U.S. Pat. Nos. 5,243,908; 5,683,190; 5,526,271; 6,607,095; 6,050,054; 5,293,465; 5,688,729; all of which are incorporated herein by reference in their entirety; disclose franking machines which may comprise franking heads, feeders, folders and user interfaces as examples. With franking machines aspects, such as device security and PKI Key management require secure communication between a service provider and the franking machine user. Typically, this secure communication is established over the users LAN (Local Area Network) or analog phone lines. A problem arises when the LAN is down or firewall access prevents the service provider to access the franking machines for critical items such as periodic required resets. A further problem arises where there are insufficient phone lines requiring the user to move individual franking machines to the line. Accordingly, there is a desire to provide a simple and cost effective method of securely connecting a service provider to franking machines.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS
Referring to FIG. 1, there is shown a block diagram of a system 10 in which the method of the exemplary embodiments could be utilized. Although the present invention will be described with reference to the exemplary embodiments shown in the drawings, it should be understood that the present invention can be embodied in many alternate forms of embodiments. In addition, any suitable size, shape or type of elements or materials could be used.
FIG. 1 shows a system diagram 10 where franking machines 36, 38, 40 communicate via GPRS 28 to a cellular carrier 26. Here the franking machine(s) may be authenticated via the GSM system whereby a secure encrypted channel is established. Here, the cellular carrier 26 may route the call via a secure network 22, for example a VPN or virtual private network, to the service provider 2, for example Neopost via gateways 20, internet 18, ISP 14 or otherwise. In the embodiment shown, GSM providers/clients are required to implement authentication/secure communications. Communications security may then be based on a worldwide implemented/supported standard. As a result of the cellular communication, firewall and network issues are eliminated at the customer site. Here, the communication channel may always be open. In the embodiment shown, cellular connectivity 30, 32, 34 may be provided, for example, as an optional upgrade for franking machines 36, 38, 40 already deployed in the field at a given site(s). Cellular communication may be taken advantage of, for example, as a standard to reduce the cost of doing business leveraging it, for example, for device security, PKA management where device communication between franking machines 36, 38, 40 and value added services 12 is implemented at the same or different remote sites. For example, a channel may be provided that is always on for constant communication between the value added services and the device or franking machine where the cellular based communication eliminates customer or user LAN issues, for example, firewalls, availability and access issues. Analog lines may be provided in offices where such lines may be scarce and where they may also be costly. For example, a franking machine may need an analog line for doing secure encrypted functions, for example such as resets or key resets where a new public/private may be established by individual. Here, security needs to be maintained to prevent corruption whereby periodic updates are required. Such updates, for example, require secure communication. In alternate embodiments, other secure or unsecure communications may be applied to other secure or unsecure functions. Alternately, a LAN may be used where customer network issues with firewalls may arise. In the present embodiment, cellular based connectivity is provided to the franking machine(s) to avoid such network or firewall issues. Here, the infrastructure that is used, for example, with cell phones may be applied to franking machines to connect securely, for example, to the reset service provider 12 infrastructure. Franking machines 36, 38, 40 may be provided with the cellular connectivity integrated into the machines. Alternately, current fielded machines may be modified, for example, with or without software change by connecting to a separate port or removing the modem and adding an adapter board that would interpret some of the modem dial up connectivity calls and pass through the rest of the information unchanged. Here, a cost effective adaptation is provided. For example, in the case of a field upgrade, franking machine 40 may have a main board having a port, for example, a RS232 connector attached to a modem. Franking machine 40 may be upgraded or new systems provided by removing the modem and attaching an adapter 34 having a cellular modem, for example, GSM in particular, to the franking machine. Here, the adapter may do the handling for the dial-up allowing communication to pass through. Alternately, the franking machine may be configurable or provided with multiple communication mechanisms, for example, analog dial up, GSM, LAN or otherwise and be capable to know the difference between a modem and a GSM modem, where an adapter is not required.
As shown in FIG. 1, a system 10 is provided where the franking machine(s) 30, 32, 34 connect through a cellular carrier 26. The connection between the franking machine(s) 36, 38, 40 and the cellular carrier 26 may be authenticated and the channel(s) 28 may then be an encrypted, secure channel 28. Such secure connection 28 may be provided via the cellular carriers, where the cellular carrier may rout the call via a VPN 22 to the service 12, for example, to reset provider (Neopost) 2, where the data is processed. The GSM provider 26 and the clients may implement the appropriate security level, for example, where such security schemes may be implemented worldwide as a standard that may be leveraged to eliminate access via conventional methods, such as firewalls and analog lines. The communication 30, 32, 34 may be provided in an “always on” state whereby when the system franking machine can handle incoming messages, such messages may be provided. Alternately, in a typical mailroom environment insufficient analog lines may be provided where the users are required to frequently move franking machines to the analog lines to do resets. Here, the modem 34 may alternately be removed from the franking machine 40 and put, for example, in a harness such that a connection externally with cellular modem may be provided where the user may move the cellular modem from machine 40 to machine 38 connected to the franking machine 38 where all the resets for the various machines may be performed without having to move the machine(s) providing an increased utilization and improved machine usability. Here, the cost associated, for example, with an analog line or multiple analog lines may be shifted elsewhere, for example, to the cost of reset budget service or rental cost of PSD or some service. Here, cellular providers 26 may have telemetry plans that allow a user to subscribe at a reduced cost. In this manner, cellular wireless communication may be taken advantage of to reduce the cost of doing business. Example applications include device communication security and PKI management or otherwise where cost and complexity is reduced. Here, the device communication channel may always be on line and customer LAN issues may be eliminated. In alternate embodiments, periodic communication access may be applied. In one embodiment, the technology may be implemented with minimal or no hardware or software changes to existing, installed franking machines. Here, mobile communication is applied to franking machines 36, 38, 40, such as through global system for mobile communication (GSM) 28 as a cellular solution for connectivity. Here, the hardware and connectivity costs may be significantly lower as compared to analog or networked lines.
Referring again to FIG. 1, there is shown a block diagram of a system 10 in which the method of the present invention could be utilized. Additional data, for example, service data, billing data or utilization data or otherwise, may be stored at device 40 or transferred from device 40 to a value added services application 2, for example, transferred over the world wide web 18 to value added service application 2 on a server 2. In alternate embodiments, data may be collected and/or processed further up or down stream of device 40 and services application 2. Connections 30, 32, 34 may be utilized for the additional data or additional network connections may be provided and may be any suitable network, such as a local area network, wireless network or otherwise. In alternate embodiments, the additional data may be stored locally or stored over a network where value added services 2 does not require access over web 18 and where value added services application 2 does not reside on device 40. In alternate embodiments, additional data may be transferred, for example, where a user such as the originator or a postal service may access the data from value added services application 2 over network 6 via user PC 4. Alternately, the data may be posted to a website and accessed by application 2 or PC 6 via web 18. Although the different functions and data access points are shown linked by the world wide web, other suitable access or data communication methods may be provided, for example, cellular, networked or wireless or other suitable methods. Here, connection 30, 32, 34 may be real time, scheduled by device 40 or by remote center or application 2. In alternate embodiments, more or less users, applications or networks may be provided.
