An improved method and system are disclosed for processing prioritized wireless calls. One embodiment of the present invention includes a method of providing prioritized wireless services, comprising the steps of: receiving a request for prioritized wireless service from a mobile device; determining the availability of a radio channel without obtaining the priority of the request; and if no radio channel is available, assigning a priority to the request and queuing the request according to the assigned priority.

System and method of handling prioritized wireless calls for mobile devices operating in an analog or TDMA mode

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.

Radio channel allocation for national security and emergency preparedness calls

A method and apparatus for completing a priority call to a wireless border switch. A priority or preemption request is transmitted as part of the signaling messages used to set up a call. A border switch is a switch which is used in conjunction with the switch indicated by the last-seen pointer from an HLR entry for the called terminal to page a called station. The switch indicated by the last-seen pointer transmits the priority request to a border switch, to indicate that the call should be given priority treatment. Further, preemption service for calls terminating on a wireless station can be provided. Advantageously, priority and preemption treatment can be provided for calls originated by wireless or landline stations and terminating on mobile station destinations that are served by a border switch; preemption or priority service can be provided for calls to a wireless station originated from a landline station; and preemption service can be provided for calls to a wireless station from a wireless station.
