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. | 03-27-2014 |

The influence of historical success or failure may degrade over time so that the rankings may be adjusted to reflect changes in network topography. A given source node, when computing alternate paths through the network, may preferentially select neighbors to perform alternate path calculations on historically higher scoring nodes before performing calculations on historically lower scoring nodes. Several different criteria may be used to stop the alternate path calculation process before considering all neighbors. The neighbors may be loop free neighbors or U-turn neighbors. | 12-13-2012 |

20120120877 | EXPEDITED CALL SETUP - An origination terminal initiates a call by providing a third party call control message in association with a traffic channel request. While the traffic channel is being established, the service node may initiate third party call control to initiate a call leg to the destination terminal on behalf of the origination terminal. As such, the destination call leg is initiated earlier. Since the destination call leg is initiated earlier, a corresponding ringback message indicating that a call is being presented to the called party is provided to the origination terminal sooner. When the ringback message is received quickly, a corresponding ringback indication may be presented to the caller in less time than was previously possible. The process is made even more efficient by waiting until the ringback message is received from the destination terminal before providing the SDP information, or communication information, for the origination terminal to the destination terminal. | 05-17-2012 |

20120115500 | Method and System of Managing Wireless Resources - The invention provides for the management of wireless resources, which can reduce call blocking by allowing high priority services, under suitable conditions, to use resources allocated to low priority services. Thus high priority services can pre-empt the usage of wireless resources by low priority services. This has the advantage of reducing call blocking for high priority calls, while permitting low priority calls to have more access to radio resources than conventional systems with the same call blocking rate. Thus a base station can implement a preemption mechanism that would reclaim Walsh Code and Forward Power resources from an active Supplemental Channel (SCH) burst in order to accommodate incoming Fundamental Channel (FCH) requests. | 05-10-2012 |
