Abstract
The present invention relates to wireless telephone networks, and more particularly to the allocation of radio channels to calls in CDMA-based systems when their Radio Access Networks (RAN) are congested. A Base Station (BS) receives a call origination from a mobile device. The BS communicates information about the call and about its radio availability to a Mobile Switching Center (MSC). The MSC determines the priority of the call and how the call should be treated by the BS based on the supplied information. The MSC communicates the treatment information and the priority information back to the BS.When the RAN is congested, high-priority calls are queued. These high-priority calls are served based on allocation specification in which radio channels may be assigned to low-priority calls, which are not queued, while there are still calls in the queue.
