IN A CLOUD-BASED COMMUNICATION SYSTEM

BACKGROUND OF THE INVENTION

[0001] Real-time latency sensitive applications, such as Next Generation Call Processing (NGCP), real-time stock trading, high performance computing, in-memory data management, and IoT controller applications, are designed to use a cloud-based multi tenant architecture. NGCP servers are designed to process service requests, such as a group call, from all customers. The cloud-based solution has the ability to use both static and dynamic cloud resources. However, static resources carry a fixed cost, regardless if they are used or not. Additionally, dynamic resources can be added but at a significantly higher cost than static resources. Further, adding dynamic resources requires time and must be added such that there is no impact to call services.

[0002] Two problems that arises from NGCP servers are Quality of Service (QoS) and Grade of Service (GoS). If required cloud resources are not obtained and useable in a timely manner, the QoS will suffer and may prove to be insufficient for the call needs.

[0003] In addition, an inefficient use of cloud resources leads to a higher cost. Idle static resources are not an efficient use of budget, while dynamic resource access is costly.

[0004] Therefore, a need exists for a method and system of accessing necessary

resources for service requests while minimizing the cost of such services.

Wireless connections or a combination of wired and wireless connections are also possible.

[0017] Electronic processor 204 may include a microprocessor, application-specific integrated circuit (ASIC), field-programmable gate array, or another suitable electronic device. Electronic processor 204 obtains and provides information (for example, from storage device 206 and/or communication interface 208), and processes the information by executing one or more software instructions or modules, capable of being stored, for example, in a random access memory (“RAM”) area of storage device 206 or a read only memory (“ROM”) of storage device 206 or another non-transitory computer readable medium (not shown). The software can include firmware, one or more applications, program data, filters, rules, one or more program modules, and other executable instructions. Electronic processor 204 is configured to retrieve from storage device 206 and execute, among other things, software related to the control processes and methods described herein.

[0018] Storage device 206 can include one or more non-transitory computer-readable media, and may include a program storage area and a data storage area. The program storage area and the data storage area can include combinations of different types of memory, as described herein. In the embodiment illustrated, storage device 206 stores, among other things, instructions for the processor to carry out the method of FIG. 3.

[0019] Communication interface 208 may include a transceiver (for example, an LTE modem, an FM transceiver, or a Wi-Fi or Ethernet transceiver) for communicating with RF Site 104, RF Site 105, or Dispatch Site 106. Communication interface 208 can also communicate with communication networks.

[0020] FIG. 3 depicts a flowchart 300 of a method for allocating resources in a cloud- based communication application in accordance with an exemplary embodiment of the present invention. In accordance with this exemplary embodiment, the cloud- based communication application periodically predicts the cloud resources needs and adjusts the desired state configurations based upon this need. In accordance with a further exemplary embodiment, the cloud-based communication application predicts the cloud resources needs and adjusts the desired state configurations based upon incident event triggers. In accordance with a further exemplary embodiment, the cloud-based communication application predicts the cloud resource needs and adjusts the desired state configurations based upon massive infrastructure or user configuration changes.

[0021] Cloud-based communication application 101 forecasts (301) a traffic envelope pattern. In accordance with an exemplary embodiment, cloud-based communication application 101 forecasts the traffic envelope pattern across Cloud-Based

Communication System 100 via machine learning. Cloud-based communication application 101 preferably forecasts utilizing unsupervised machine learning. The accuracy of the traffic envelope pattern will increase as more data is collected. Resources are modified based on learned and predicted patterns. In an exemplary embodiment, the traffic envelope pattern is a weighted mixture of different traffic types. In this exemplary embodiment, call signaling and voice processing traffic has a higher weight than resource management traffic.

[0022] Cloud-based communication application 101 sets (3031 a potential maximum traffic amount. In accordance with an exemplary embodiment, cloud-based communication application 101 sets the potential maximum traffic amount using at least cloud platform information and call properties.

[0023] Cloud-based communication application 101 bounds (3051 the potential

maximum traffic amount, preferably using bounding parameters. In accordance with an exemplary embodiment, the bounding parameters at least one of a count of users, configured capabilities (such as voice, data, or location), user configurations, system infrastructure information, data service capability, call properties, consoles count, sites count, active channels count, failed channels count, number of sites per call, number of consoles per call, active talkgroups count, active talkgroups capabilities; and infrastructure configurations (such as number of sites and number of channels and channels capability, or call properties such as number of sites involved in a call, call type and corresponding durations).

[0024] Cloud-based communication application 101 adjusts (307) the traffic envelope pattern based on an incident context. In accordance with an exemplary embodiment, the incident context includes a type, a location, impacted sites, impacted channels, impacted systems, and an historical traffic pattern. The incident context, or trigger, can comprise a national emergency being declared, a planned social event, a particular forecasted weather situation, or a learned incident from RSS feeds or any crowd- sourced social network. The historical traffic patterns can comprise historical behaviors of a traffic envelope pattern regarding a similar incident context.

[0025] Cloud-based communication application 101 consolidates (309) resources. In accordance with an exemplary embodiment, cloud-based communication application 101 consolidates resources by determining at least one availability zone that includes a system that is able to add capacity based on the at least one availability zone and the incident context. Cloud-based communication application 101 then increases capacity on the at least one availability zone. Cloud-based communication application 101 preferably increases capacity by creating containers on the at least one availability zone. Cloud-based communication application 101 allows proper lead time to change the desired state and to create and deploy containers.

[0026] Cloud-based communication application 101 determines (311) if there is a new burst traffic pattern. If it is determined that there is not a new burst traffic pattern, the process ends (3991. In accordance with an exemplary embodiment, cloud-based communication application 101 performs passive performance monitoring to determine if there is a new burst traffic pattern. For example, cloud-based communication application 101 determines that there is a new burst traffic pattern when resource utilization reaches a predetermined percentage. In one exemplary embodiment, this predetermined percentage is 70%. In a second exemplary embodiment, cloud-based communication application 101 determines that there is a new burst traffic pattern, in this exemplary embodiment a lower need of resources, when the resource utilization drops below a predetermined percentage, such as below 15%.

[0027] If cloud-based communication application 101 determines that there is a new burst traffic pattern in step 311, cloud-based communication application 101 adjusts (313) call resource resources. In accordance with an exemplary embodiment, when a new burst pattern occurs, cloud-based communication application 101 triggers additional resource allocation that has not been learned from prior traffic data. The process then ends (399).
