  • Patent number: 7340254
    Abstract: Measurement opportunities are provided to a wireless transmit/receive unit (WTRU) operating with a switched beam antenna in a CDMA wireless communication system. The switched beam antenna is a smart antenna generating a plurality of directional beams and an omni-directional beam. The bursty nature of packet data transmission generates periods of inactivity or low traffic during a call. The WTRU switches to antenna beams other than the selected antenna beam for receiving and measuring signals during these periods of inactivity or low traffic. Moreover, if the network has knowledge of the fact the WTRU is operating using a switched beam antenna, the network can use this information when making decisions on channel allocations, thus providing frequent measurement opportunities to the WTRU in order to support the switched beam antenna operation.

  • Patent number: 7308264
    Abstract: Measurements for identifying pre-candidate cells are made by a wireless transmit/receive unit (WTRU) operating with a switched beam antenna in a wireless communication system. The switched beam antenna is a smart antenna generating a plurality of directional beams and an omni-directional beam. The WTRU measures signals from cells not in an active set of cells to define a pre-candidate set of cells. Measured signals from cells in the pre-candidate set of cells are compared to a threshold, and the corresponding cells are moved from the pre-candidate set of cells to a candidate set of cells based upon the comparison to the threshold. A measurement report is then sent to the network.

  • Patent number: 7155267
    Abstract: An apparatus and method are provided for monitoring an antenna state of a mobile station. A resister may be provided between a battery voltage terminal and a power source voltage terminal of a power amplifier. A voltage level corresponding to a dropped amount of a voltage due to the resister may be generated and compared with a previously stored voltage level to determine whether current consumption of the power amplifier has been increased. If the increased amount of the current consumption of the power amplifier is large, the currently connected antenna may be determined to be in an abnormal state and a transmission path may be switched to another antenna. If two antennas provided in the mobile communication are in an electrically abnormal state, a baseband chip may inform a user of the abnormal state of the antenna. Accordingly, an output level degradation generated when the antenna is operated in an electrically abnormal state and shortening of the life span of a battery can be prevented.

  • Patent number: 6889040
    Abstract: The possibility of incompatibility between wireless communication system stations having the most recent protocol revisions is addressed by transmitting from the base station to a mobile station characteristics that identify a mobile station group that is restricted to using less than the most recent protocol revision. Using less than the most recent protocol revision may involve using an earlier revision or a subset of the most current protocol revision. This permits a base station to direct mobiles to avoid using protocol revisions or features of protocol revisions that have been insufficiently tested or that have a history of problems for a particular base station/mobile station combination.

  • Patent number: 6807414
    Abstract: A method of transferring the identity of subscriber A to a second centre (VMSC) serving a roaming subscriber B. A first centre (GMSC) receives a call set-up request from subscriber A and defines the identities of the subscribers and the address of the second centre (VMSC). It then sends to a service control point (SCP) an intelligent network service initiating message. The service control point (SCP) sends to the second centre (VMSC) an indication stating the identity of subscriber A and that a call is incoming to subscriber B. The second centre (VMSC) may send corresponding information to subscriber B's mobile station (MS) and receive from it a response, which it sends to the service control point (SCP). The latter analyzes the response and issues in response thereto necessary call set-up instructions to the first centre (GMSC) which sets up the call to subscriber B's mobile station (MS), provided that said response indicates that subscriber B accepts said call.
