A system and method is provided for fast call set-up in a wireless communication system. A base station sets up a call from a mobile station by sending null frames to the mobile station on a forward traffic channel instead of sending a base station acknowledgement order. The mobile station sends a traffic channel preamble to the base station on a reverse traffic channel instead of sending a mobile station acknowledgment order. The fast call set-up procedure of the present invention reduces the call set-up time from approximately two (2) to three (3) seconds to approximately two hundred milliseconds (200 msec) to three hundred milliseconds (300 msec).

System and method for providing fast call set-up in a wireless communication system

A wireless communication system, such as a cellular communication system prioritizes calls to have a low, regular or high priority. The communication channels provided by a base station are divided into regular channels and reserved channels. All calls are connected on regular channels until the regular channels are all full. When the regular channels are all full, then regular priority calls are connected as low priority calls or not at all. If a regular priority call is connected as a low priority call it is connected via a reserved channel. Once all the reserved channels are full, then a high priority call is attempted to be connected by dropping a low priority call and using the reserved channel that the low priority call was using.

Cellular telephone system which increases efficiency of reserved channel usage

A wireless communications network and method include a home system, a serving system, and authentication failure triggers. The home system includes an authentication center, a network information element, and a prescribed authentication capable mobile station. The authentication center performs an authentication of the prescribed mobile station upon a network access by the mobile station. Authentication includes use of shared secret data particular to the prescribed mobile station. The serving system includes a network access element and a network information element associated therewith. The serving system is capable of performing authentication upon authentication capable mobile stations. Lastly, the authentication failure triggers and shared secret data are shared with the serving system by the authentication center of the home system upon the mobile station's initial system access. The authentication failure triggers include instructions for use by the serving system with respect to authentication failures which may occur during a subsequent serving system access. The authentication triggers direct the serving system to handle authentication failures according to the authentication policies of the home system's authentication center. Therefore, the requirement for the authentication failure report operation is advantageously reduced.
