Abstract: A PBX (10) is connected to a mobile telephony network (40) via a PSTN (20) and via a LAN (90) and data network (30). A mobile telephone (50) served by the mobile network, has a separate data channel (100). The invention describes a way to integrate mobile telephones as extensions of the PBX and to provide them with functionality similar to that of a wired digital PBX system telephone (70). The data channel of the mobile telephone is used to give the PBX access to the user interface devices of the telephone. The speech path between the PBX and the mobile telephone may be set up in the direction from the PBX to the mobile telephone, even when the call was initiated at the telephone. The invention relies only on the basic voice and data communications services of the mobile telephony network, and therefore provides independence from the network operator.

Abstract: Load balancing between agents in a network skillset has become a particular problem. Not only is there a need to ensure efficient use of agent resources in the network skillset but increasingly labor law and union requirements mean that work must be shared between agents in an equitable manner. A source contact node in a network of contact centers requests nodal longest idle agent information from the other contact centers in the network. Using this information a network longest idle agent is identified and the incoming contact routed to that agent. A reservation system is used in combination with the longest idle agent information in order to prevent dropped contacts and to ensure equal sharing of work between agents in a network skillset. Contact center servers are linked over a separate network, isolated from a network linking the contact center switches.

Abstract: TDD access equipment modified by introducing a frequency change at the normal TDD guard point, with respective downlink or uplink periods for individual subscriber stations offset to form overlapping frames. Cyclo-stationary processing, block equalization, and burst timing coordination allow the boundary between downlink and uplink portions of both frames to be set dynamically, improving spectral efficiency. Fast frequency switching within an allotted physical slot enables synchronization of time-sharing the dedicated frequencies to be maintained among subscriber stations. Duplex spacing between downlink and uplink frequencies for individual subscriber stations, combined with in-depth filtering of received signals, prevents spurious out-of-band transmission signal strength from reaching an interference level.
