A processor migrates a state of the contact center from a first deployment state to a second deployment state. The processor records the steps in migrating from the first deployment state to the second deployment state, and stores the recorded steps in association with metadata describing the second deployment state. The processor monitors health of the second state, and takes an action for moving the state of the contact center to a healthy state in response to determining that the second deployment state is unhealthy. The migrating may be based on detecting a condition relating to operation of the contact center. The processor dynamically adjusts at least one hardware or software resource for the contact center based on the detected condition for migrating the state of the contact center from the first to the second deployment state. | 2014-03-27 |
20140086402 | MATCHING USING AGENT/CALLER SENSITIVITY TO PERFORMANCE - A method, system and program product, the method comprising: obtaining for each call in one set of calls a respective pattern representing multiple different respective data fields; obtaining performance data for the respective patterns of the calls; obtaining performance data for the respective agents; determining agent performance sensitivity to call pattern performance for agents in a set of agents comprising the agent performance data correlated to call performance data for the calls the agent handles; and matching a respective one of the agents from the set of agents to one of the calls based at least in part on the performance data for the respective pattern of the one call and on the agent sensitivity to call performance for the respective one agent of the set of agents. | 2014-03-27 |
20140086403 | USE OF ABSTRACTED DATA IN PATTERN MATCHING SYSTEM - Method, system and program product, for operating a call center system, the method comprising: obtaining performance data for agents in a set of agents; obtaining a respective abstracted data stream for multiple calls, each respective data stream having multiple different locations along the abstracted data stream representing multiple different respective fields, the meaning for the field data in the respective different locations for the different respective fields not known by the system; determining respective patterns for the respective data streams; obtaining performance data for the respective patterns; matching using a selected matching algorithm one of the agents from the set of agents to one of the calls based at least in part on the performance data for the respective pattern of the call and on performance data for the respective agents of the set of agents. | 2014-03-27 |
20140086404 | MATCHING USING AGENT/CALLER SENSITIVITY TO PERFORMANCE - A method, system and program product, the method comprising: obtaining for calls in one set of calls a respective pattern representing one or multiple different respective data fields; obtaining performance data for the respective patterns of the calls; performance data for agents in a set of agents; determining pattern performance sensitivity to agent performance comprising the pattern performance data correlated to agent performance data; matching a respective one of the agents from the set of agents to one of the calls based at least in part on the performance data for the one agent and on the pattern performance sensitivity to agent performance for the respective call. | 2014-03-27 |
20140086405 | MANAGEMENT OF QUEUES IN CONTACT CENTRES - Contacts are managed within a contact centre by representing each contact as a software object which contains skillset and priority identifiers. Contact objects are queued relative to one another by means of references to and/or from the object(s) immediately ahead of and behind each contact. In this way a conventional queue can be dispensed with. Queries can be made to a plurality of contact centres across a network to identify objects matching certain criteria at the top of each local queue. In this way a set of local queues substitutes for a network queue providing increased resilience in the case of the failure of any individual component of the network or of the network itself. | 2014-03-27 |
20140086406 | Key Management Using Security Enclave Processor - An SOC implements a security enclave processor (SEP). The SEP may include a processor and one or more security peripherals. The SEP may be isolated from the rest of the SOC (e.g. one or more central processing units (CPUs) in the SOC, or application processors (APs) in the SOC). Access to the SEP may be strictly controlled by hardware. For example, a mechanism in which the CPUs/APs can only access a mailbox location in the SEP is described. The CPU/AP may write a message to the mailbox, which the SEP may read and respond to. The SEP may include one or more of the following in some embodiments: secure key management using wrapping keys, SEP control of boot and/or power management, and separate trust zones in memory. | 2014-03-27 |
