<p>The system for wireless communication connection handoff service addresses the CDMA radio congestion problem from the mobile switching center point of view, thereby providing a unified approach to the problem of access failures for CDMA wireless communication service. In operation, the mobile subscriber station forms a message and forwards it to the mobile switching center to indicate the signal strength of the various base stations that have responded to the access probe. The mobile switching center saves this data for later use when the mobile subscriber station moves out of range of the initially selected base station. The mobile switching center reviews the stored data and, if a CIC is available to one of the identified base stations, the channel is allocated and the stored data is flushed. Thus, the need for another probe sequence is avoided and the initially provided base station signal strength data is reused to process a call handoff. <IMAGE></p> |
