ABSTRACT:
An apparatus and method for enhancing channel utilization in a CDMA system are provided. The method includes the steps of receiving a service request for data transmission on a channel; transmitting a service feature by the CDMA system to a channel management module, whereby a channel multiplexing method and a channel bandwidth are selected by the channel management module based on the service feature; transmitting data, wherein when a data transmission rate changes to an extent that capacity of a currently configured channel cannot satisfy a requirement of the data transmission rate, the currently configured channel is re-assigned by the channel management module; accounting a variation of the data transmission rate by the service access module during the data transmission; modifying the service feature of the current service; and updating a corresponding record of the service feature in a system database, so that when a next service request of a same service type of the user is received, updated record of the service feature is used as a reference for configuring and assigning the channel. Accordingly, the channel utilization is enhanced, and the number of times for re-assigning a channel is significantly decreased.
