BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 illustrates a typical, non-limiting embodiment of the system level architecture employed in the disclosure of present;



DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The improved method and system for Multimedia Messaging Service (MMS) rating and billing disclosed herewith offers members skilled in the art of telecommunication network operation and intermediation an innovative mechanism for real-time rating and charging for MMS messages. (Both Mobile Originated (MO) and Mobile Terminated (MT) messages are encompassed by elements of the application).
With reference now to FIG. 1, the improved device for Multimedia Messaging Service (MMS) rating and billing 20 in particular is juxtaposed and remains contingent upon, in the preferred embodiment, an Open Charging (OC) middleware platform and gateway system 10 as detailed in patent application Ser. No. 10/307,335 , for mediation with a prepaid or postpaid platform. Noble technicians skilled in the art will recognize that the invention of present need not be limited to the aforementioned Open Charging (OC) ruiddleware platform and gateway system and other similar network implementations may be employed without diluting the intent and scope as such. However, to facilitate ease of instruction and overall efficacy of purpose the recourse to the Open Charging (OC) middleware platform and gateway system 10 is expressly invoked and relied upon.
Furthermore, to facilitate the instruction of the art, the improved Multimedia Messaging Service (MMS) rating and billing device 20 disclosed herewith interfaces with the Multimedia Messaging Service Center's (MMSC) 30 Real Time Payment Protocol (RTPP) interface for real-time Mobile Originated MMS rating and charging. (Multimedia Messaging Service (MMS) rating and billing device 20 can be implemented as part of a complete system. Multimedia Messaging Service (MMS) rating and billing device 20 operates according to an improved method. Multimedia Messaging Service (MMS) rating and billing. Multimedia Messaging Service (MMS) rating and billing device 20 is also referred to herein as invention 20. The invention 20, which is articulated as part of computer program product, accepts RTPP triggers from a MMSC 30 and subsequently rates, and charges messaging traffic against the Open Charging (OC) middleware platform and gateway system 10. Technicians skilled in the art will recognize that the invention of present need not be limited to the aforementioned Open Charging (OC) middleware platform and gateway system and other similar network implementations may be employed without diluting the intent and scope as such. Technicians skilled in the art will also recognize that any number of protocols, triggers and interfaces may be employed herewith, and indeed, remain only bound by the state of the art and the reference to any one protocol (or similar rules, methods and means for the transmission of data) remains purely for the purposes of simplicity and ease of instruction, and do not serve to dilute the application and scope of the invention as such.
In alternate embodiments, the invention 20, may also access an external Lightweight Directory Access Protocol (LDAP) subscriber database 50 for subscriber profile queries. Technicians skilled in the art will also recognize that the triggers, protocols and like commands used among the network elements remain only bound by the state of the art and do not serve to dilute the generality of such interaction.
The MMSC 30 initiates connections to the improved method and system for Multimedia Messaging Service (MMS) rating and billing 20; and therewith once the connection has been established, the MMSC 30 performs transactions by submitting requests to the requisite logic of the disclosed invention 20.
In the preferred embodiment, the computer program product which implements the invention 20 disclosed herewith has been articulated with particular ‘fail-safe’ logic. Indeed, wherever the improved method and system for Multimedia Messaging Service (MMS) rating and billing 20 is invoked it attempts to connect to the external LDAP subscriber database 50. In the event the connection is lost, the node implementing the invention 20 will reattempt the connection at periodic intervals for a configurable number of times. Where re-connection remains unrealized, the improved method and system for Multimedia Messaging Service (MMS) rating and billing 20 will instinctively switch to one of the following configurable modes. In “reject” mode, all incoming RTPP triggers will be rejected immediately until connection is re-established. Connection attempts are performed at periodic intervals. In “passthrough” mode, all incoming RTPP triggers will be successfully acknowledged immediately until connection is re-established. Connection attempts are performed at periodic intervals. When a connection is broken, an SNMP trap will be raised. Once the connection is re-established, another SNMP trap is generated to clear the alarm.
At the core of the invention 20 remains the rating engine and the logic, routines and rules used therewith, articulated to provide real-time, high performance rating for MMS messages. The Rating Rule definition allows a member skilled in the art to determine the rate for each MMS. In the preferred embodiment, rules are to be considered in order. The first rule that matches a given MMS Event will be used and remaining rules will be ignored. Where no rules match, the MMS will be assumed to be free of charge. No charging will occur.
The member skilled in the art may insert, change and delete rules as they deem appropriate. For ease of reference, the following table (Table 1) seeks to outline the rating rule architecture in a non-limiting, illustrative manner.

The invention 20 interfaces with an Open Charging (OC) middleware platform and gateway system 10 as detailed in patent application Ser. No. 10/307,335, for mediation with the wireless subscriber's prepaid account in performing the requisite balance deduct function. Noble technicians skilled in the art will recognize that the invention of present need not be limited to the aforementioned Open Charging (OC) middleware platform and gateway system and other similar network implementations for balance deductions may be employed without diluting the intent and scope as such.
Additionally, when handling group messages, the invention 20 interfaces with an Open Charging (OC) middleware platform and gateway system 10 as detailed in patent application Ser. No. 10/307,335, to query the balance of the wireless subscriber's prepaid account. Noble technicians skilled in the art will recognize that the invention of present need not be limited to the aforementioned Open Charging (OC) middleware platform and gateway system and other similar network implementations for balance queries may be employed without diluting the intent and scope as such.
Much like the ‘fail-safe’ scenario outlined prior (in regards to the external LDAP subscriber database 50), wherever the invention 20 is invoked the art therewith attempts to connect to the Open Charging (OC) middleware platform and gateway system 10. In the event the connection is lost, the node implementing the invention 20 will reattempt the connection at periodic intervals for a configurable number of times. Where re-connection remains unrealized, the improved method and system for Multimedia Messaging Service (MMS) rating and billing 20 will instinctively switch to one of the following configurable modes. In “reject” mode, all incoming RTPP triggers will be rejected immediately until connection is re-established. Connection attempts are performed at periodic intervals. In “passthrough” mode, all incoming RTPP triggers will be successfully acknowledged immediately until connection is re-established. Connection attempts are performed at periodic intervals. When a connection is broken, an SNMP trap will be raised. Once the connection is re-established, another SNMP trap is generated to clear the alarm. Technicians skilled in the art will recognize that the invention of present need not be limited to the aforementioned Open Charging (OC) middleware platform and gateway system and other similar network implementations for balance queries may be employed without diluting the intent and scope as such.
Another singular aspect of the invention of present, remains the ability to rate and charge for Group Messages. A Group Message is defined as an MMS message addressed to multiple recipients. In the all-or-none scenario, where the originating wireless subscriber does not have sufficient fund to send the MMS message to all the recipients, the whole Group Message Transfer is rejected and no MMS message is delivered to any of the recipients.
In elucidating further how the improved method and system for Multimedia Messaging Service (MMS) rating and billing handles Group Messages, the following steps should prove illustrative. In the first instance, determine if the incoming Debit Request received from the MMSC belongs to a Group Message by examining the MMSC_NUMBER_OF_RECIPIENTS field. Where the MMSC_NUMBER_OF_RECIPIENTS is greater than 1, the Debit Request is for Group Messaging. Next confirm if the Debit Request is for the first recipient by searching corresponding MMSC_A_MSISDN and MMSC_MSG_ID in the Group Message Store. The Group Message Store holds all outstanding Group Message information which includes, but need not be bounded by, MMSC_A_MSISDN, MMSC_MSG_ID, MMSC_NUMBER_OF_RECIPIENTS, number of processed recipients, each recipient's information (B-Party Address and Service Type), balance, total rate, SCP ID.
Where the Debit Request is for the first recipient, an LDAP subscriber query on A-Party will be performed and a new Group Message entry will be created in the Group Message Store. In addition, the logic of the invention can be articulated to perform a balance query to Service Control Point (“SCP”)4 on the first recipient message, a BalQ will be triggered to the Open Charging (OC) middleware platform and gateway system and the subscriber balance will be returned. Otherwise, a configurable fixed balance will be used instead. Members skilled in the art will recognize that the invention of present need not be limited to the aforementioned Open Charging (OC) middleware platform and gateway system and other similar network implementations for balance queries may be employed without diluting the intent and scope as such.
Next, the art of the invention performs an LDAP subscriber query on B-Party address (if it is a National number), rates the message, and subtracts the amount from the balance. Next, an update is performed to the corresponding Group Message entry with the Total Rate and B-Party information. Where the Total Rate exceeds Balance, the invention clears the corresponding Group Message entry and sends a warning message (where configured by a member skilled in the art) to A-Party. Also, a Debit Response with status code 0x6000 (insufficient funds) will be sent back to MMSC via the original node. Credit Requests may then be triggered by the MMSC to refund a charge for each recipient and should all be positively acknowledged.
If the Debit Request is not for the last recipient and the Total Rate does not exceed Balance, the invention positively acknowledges the Debit Request to MMSC via the original node. Whereas, where the Debit Request is for the last recipient, another balance query is performed by triggering an Open Charging (OC) middleware platform and gateway system as detailed in patent application Ser. No. 10/307,335, as to minimize the fault window. If the Total Rate exceeds the new Balance, a warning message (where configured by a member skilled in the art) is sent to A-Party and a Debit Response with status code 0x6000 (insufficient funds) will be sent back to MMSC via the original node. Otherwise, the logic of the invention positively acknowledges the Debit Request to MMSC via the original node and then performs a sequence of BalDeduct (for each recipient) to the Open Charging (OC) middleware platform and gateway system to debit the wireless subscriber. The corresponding Group Message entry is cleared afterwards.
The computer program product which implements the improved method and system for Multimedia Messaging Service (MMS) rating and billing, has been articulated as to store Group Message entries (then ‘Group Message Store’), and will allow said messages to expire and eliminated after a configurable time period. This functionality and implementation is intended to deal with scenarios as MMSC node failures and related exceptions.
In alternate embodiments, the improved method and system for Multimedia Messaging Service (MMS) rating and billing may send a warning message to a prepaid wireless subscriber where said subscriber has an insufficient balance to send a Mobile Originated message. This applies to Single Recipient MMS messages (when debit fails) and Group Messages (when balance falls below 0 or debit fails). The content of the warning message remains entirely configurable (e.g. “Sorry you have insufficient funds. Please try again and thank you for playing”). The message is limited to a single SM.
