Abstract: A Voice call Precedence Over Packet Data (VPOPD) technique which would allow a customer of a wireless communication network service provider to choose whether to receive a call during an active packet data session. The VPOPD technique is a method of call processing comprising the steps of setting a feature value to be used in call processing when an associated mobile station has an active packet data session, and determining whether to reject a call termination request for the mobile station when the mobile station has an active packet data session using the feature value. The feature value may be set using a feature code transmitted from the mobile station, or provided by a service provider. If a determination to accept the call termination request is made, the following additional steps are performed: a message is sent to the mobile station to prevent race conditions from occurring, the mobile station is caused to enter a dormant state, and then the mobile is paged.

Abstract: The present invention, in illustrative embodiments, implements systems and methods for adjusting the timing of access requests in mobile communications systems, such as IS-95-A mobile telephone systems, to reduce the likelihood of request collisions—especially during periods of very high calling rates. These embodiments employ measurements of access channel occupancy, as well as system operator inputs, to develop thresholds and parameter translations at a base station. Execution of control algorithms at a base station advantageously yields modified persistence test parameters sent to mobile stations. When overload conditions are present, these modified parameters cause the mobile stations to experience variable delays through judicious control of persistence testing at the mobile stations.

Abstract: The system for increasing the call capacity of a wireless communications system degrades voice quality of the communications connections within a predetermined limit in order to increase the efficiency of the available RF spectrum as measured by the call carrying capacity of this allocated RF spectrum. This is accomplished by adjusting the transmission rate of the speech coder at the mobile subscriber unit and/or the speech coder that may be located at the mobile switching center so that the call carrying capacity of the wireless communications system is therefore increased. Additionally, the situation of call blocking is monitored to determine if frame error rate targets should be adjusted to further increase the call capacity. At times when the wireless system is not experiencing peak usage, the voice quality is restored to normal levels. The term “mobile subscriber unit” does not imply that the mobile unit is restricted to a moving vehicle.
