The following quote was obtained by the news editors from the background information supplied by the inventors: "As the demand increases for various applications within mobile telecommunications networks, service providers must constantly upgrade their systems in order to reliably provide expanded functionality. What was once solely a system for voice communications has recently grown into a heterogeneous system that enables access to various communications platforms, text messaging, and multimedia streaming, along with general Internet access. To support such applications, service and infrastructure providers have built new networks over existing voice communication infrastructure. While this has enabled added functionality without appreciable service interruptions, such makeshift modifications have served as less-than-ideal long-term solutions for a communications infrastructure. As evidenced by second and third generation networks, voice services must be carried over dedicated voice channels toward a traditional circuit-switched core, while other services, such as IP-enabled data and communications may be transmitted over a different packet-switched core, following Internet protocol (IP). This has led to unique problems, including, for example, application provision, metering and charging, and quality of experience (QoE) assurance.
"One recent attempt to enhance the dual-core approach of the second (2G, 2.5G) and third generations (3G) of mobile telecommunications standards defined by the
"The 3GPP generally describes the components of the EPC and their interactions with each other in some technical specifications, specifically, 3GPP TS 29.212, 3GPP TS 29.213, and 3GPP TS 29.214, which describe components such as a Policy and Charging Rules Function (PCRF), Policy and Charging Enforcement Function (PCEF), and Bearer Binding and Event Reporting Function (BBERF) of the EPC. These technical specifications also provided some details regarding the interactions between these components. These specifications gave some guidance on how the EPC could provide reliable data services to users, while also reliably charging subscribers for use of the IP network.
"For example, 3GPP TS 29.212, 3GPP TS 29.213, and 3GPP TS 29.214 provide some guidance on handling connectivity when multiple gateways may be used to connect a specific user device to the EPC. Specifically, the specifications provide some guidance on handling a plurality of messages from different sources, such as messages from the BBERF and PCEF. However, the technical specifications are silent on how the system should handle related messages from diverse sources.
"In view of the foregoing, it would be desirable to provide a system and method more capable of handling related messages. In particular, it would be desirable to provide a system that may take appropriate action when receiving related messages from multiple sources."
In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventor's summary information for this patent: "In light of the present need for a method for handling the related messages from diverse sources, a brief summary of various exemplary embodiments is presented. Some simplifications and omissions may be made in the following summary, which is intended to highlight and introduce some aspects of the various exemplary embodiments, but not to limit the scope of the invention. Detailed descriptions of a preferred exemplary embodiment adequate to allow those of ordinary skill in the art to make and use the inventive concepts will follow in the later sections.
"Various embodiments may relate to a method performed by a Policy and Charging Rules Node (PCRN) to process at least two messages received from a plurality of devices, the method including one or more of the following: receiving a first request from a first device, the first request associated with a first Session Binding Identifier (SBI) comprising at least one attribute associated with a first subscriber profile, identifying the first SBI associated with the first request, acquiring a lock associated with the first SBI, the acquisition of the lock indicating that processing cannot be interrupted by other requests, processing the first request, sending an answer message to the first device in response to processing the first request, modifying the lock to indicate that the processing of the first request may be modified by the receipt of at least one priority task, sending a resultant message to at least a second device after processing at least the first request, and releasing the lock.
"Various other embodiments may also relate to A Policy and Charging Rules Node (PCRN) to process at least two messages received from a plurality of devices, the PCRN including one or more of the following: a first interface that receives a first request from a first device, the first request associated with a first Session Binding Identifier (SBI) comprising at least one attribute associated with a first subscriber profile, and sends an answer message to the first device in response to processing the first request, a message mate checker that identifies the SBI associated with the first request, a locking device that maintains a lock associated with the first SBI, a rule processor configured to process the first request, acquire the lock from the locking device, the acquisition of the lock indicating that processing cannot be interrupted by other requests, modify the lock associated with the SBI to indicate that the processing of the first request may be modified by at least one priority task, and release the lock, and a second interface that sends a resultant message to at least a second device after processing at least the first request.
"It should be apparent that, in this manner, various exemplary embodiments enable dynamic binding of multiple messages originating from diverse sources. Particularly, by enabling the PCRN to synchronize messages from diverse sources, the system may act completely to a user with as little latency as possible."
