  • Patent number: 6650900
    Abstract: Logical coverage areas are dynamically rearranged to meet the traffic needs of a wireless switching system. Further, the logical coverage areas do not have to be initially provisioned during deployment of the wireless switching system since the initial determination of the logical coverage areas is automatically performed. Once the logical coverage areas are established, the logical coverage areas adapt to the changing needs of the community of wireless handsets. A first embodiment allows the base stations to control the rearrangements, and a second embodiment allows a system wireless controller controlling the wireless switching system to control the rearrangements.

  • Patent number: 6628948
    Abstract: In a wireless switching system in which base stations dynamically re-arrange logical coverage areas, when a base station enters a new logical coverage area, wireless handsets registered on the base station do not have to report individually this change in logical coverage areas to a wireless switching system controlling the wireless switching system. The base station performing the transfer from one logical coverage area to another logical coverage area informs the wireless switching system controller of the change in logical coverage areas both for the base station itself and for each of the wireless handsets registered on the base station. The base station informs the wireless handsets that the logical coverage area is being changed and informs the wireless handsets that they do not have to re-register. This reporting by the base station greatly reduces the number of operations performed when the base station moves from one logical coverage area to another logical coverage area.

  • Patent number: 6519459
    Abstract: A wireless handset does not perform a re-registration operation when its serving base station is at capacity, and a wireless controller controlling a wireless switching system is allowed to send incoming calls for the wireless handset to the base station even if the base station is at capacity. The base station signals a new call to the wireless even if the base station is at its active call capacity. The wireless handset is responsive to the incoming call to perform a base station re-direct operation to a new base station that has idle call capacity, and the call setup is completed to the wireless handset via the new base station. The base station re-direct operation is a new wireless operation. The base station re-direct operation is controlled by the system wireless controller in a second embodiment.

  • Patent number: 6374113
    Abstract: A wireless terminal is dynamically placed into a call coverage group based on the location of the wireless terminal. Similarly, a wireless terminal is dynamically removed from a call coverage group on the basis of the location of the wireless terminal. In addition, within a call coverage group, the position of a wireless terminal that is in communication with an auxiliary desktop unit is determined by a preassigned position within the call coverage group of the auxiliary desktop unit. The wireless terminal in communication with the auxiliary desktop unit is always assigned this preassigned location in the call coverage group. Other call coverage groups that are based on geographical location and where the wireless terminal is not communication with an auxiliary desktop unit have wireless terminals assigned into the call coverage path group based on a predefined algorithm.

  • Patent number: 6192234
    Abstract: Wireless terminals automatically and dynamically establish call coverage groups based on physical locations. Each location is assigned a call coverage telephone number. When a new wireless terminal enters the location, the wireless terminals automatically and dynamically determine a new call coverage path. The wireless terminals establish the new call coverage path by communicating with each other. The wireless switching system to which the wireless terminals are connected does not administer the call coverage group. The criteria utilized to establish the call coverage group is stored within the wireless terminals that will be part of that call coverage group. When a call is received by the wireless switching system for the call coverage number, the wireless switching system broadcasts a page message for the call coverage number. The wireless terminals in the call coverage group for the call coverage number each wait an individual predefined amount of time before attempting to respond to the page message.

  • Patent number: 6088442
    Abstract: Allowing the alerting of supervisors and off duty agents to conditions on a split of an ACD system via wireless terminals. The conditions under which the wireless alerting will be performed are programmed by the owner of the ACD system rather than the manufacturer. The ACD center is connected to a wireless switching system via a primary rate ISDN interface (PRI) link. The ACD system considers the wireless switching system as another ACD system and utilizes the look ahead interflow operation to communicate information to the wireless switching system concerning the condition of a split. This is done by the ACD placing informational telecommunication calls to pseudo telecommunication numbers via the PRI link to the wireless switching system. The wireless switching system is responsive to each of these pseudo numbers to interpret the pseudo number as to the wireless terminal that should be contacted and an alphanumeric message that is to be displayed on that wireless terminal.
