    Abstract: In a cellular system, a new cell measures signal strengths of different channels being used by existing cells. The new cell generates a list of candidate channels corresponding to the channels with the greatest signal strength and transmits the list to the mobile switching center (MSC) of the cellular system. The MSC determines which of the candidate channels correspond to beacons in existing cells and transmits configuration information to the new cell for those corresponding existing cells. In this way, the new cell automatically receives configuration information on its neighbor cells. If the MSC determines that the number of candidate channels that are beacons is too small, the MSC will ask the new cell to transmit additional candidate channels (i.e., those having even lower signal strength).

    Abstract: Soft handoffs in an IS-95 CDMA system or other wireless communication system are controlled using an enhanced set of soft handoff parameters which allow the system to adapt more readily to changing radio frequency (RF) conditions. In an illustrative embodiment, values for particular ones of the soft handoff parameters are selected in accordance with a set of rules, including rules such as, e.g., select the minimum value of add threshold among the members of an active set of pilots for a given mobile station; select the maximum value of drop threshold among the members of the active set; select the minimum value of drop threshold timer among the members of the active set; and select the minimum value of comparison threshold among the members of the active set. A quality measure is then determined for each of the members of the active set, based on one or more of the selected soft handoff parameter values and values of one or more additional parameters, e.g., add intercept, drop intercept and slope parameters, associated with those members. Particular values of the additional parameters are then selected based on the quality measures. The selected parameter values are then utilized in a soft handoff process, e.g., in a soft handoff process in which the given mobile station is directed to handoff from a primary base station to another base station of the system.

    Abstract: A method for controlling access of a subscriber station to a wireless communications system facilitates the maintenance of a performance target of the reverse link and desired geographic coverage of the reverse link. The method for controlling access of a subscriber station to a wireless communications system includes measuring a first performance indicator and a second performance indicator for a reverse link associated with a subscriber station seeking access to a wireless communications system. A blocking threshold value is established based upon the measured second performance indicator and may be adjusted to allow more or less blocking based on any additional metrics that characterize the performance of the current subscriber stations. The decision to grant or deny access of the subscriber station to the wireless communications system is determined based on a comparison of the measured first performance indicator to the established blocking threshold value.

    Abstract: Sharing the existing sector antennas at the base station each of which corresponds to one sector of the outer communication coverage area to create an omnidirectional inner communication coverage area. When transmitting or receiving data from a mobile in one sector of the outer communication coverage area only one antenna is used, and when transmitting or receiving data from a mobile in the inner communication coverage area all the antennas are used. This allows an increase in capacity of the hybrid inner/outer sectored cell without the additional cost of adding further antennas.
