摘要： 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.

摘要： 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. The present state of the art includes the use of mobile subscriber units in fixed wireless applications as an alternative to traditional wire telephony services.
摘要翻译：用于增加无线通信系统的呼叫容量的系统将通信连接的语音质量降低到预定限度内，以便通过该分配的RF频谱的呼叫承载能力来测量可用RF频谱的效率。这是通过调整可能位于移动交换中心的移动用户单元和/或语音编码器处的语音编码器的传输速率来实现的，从而增加了无线通信系统的呼叫承载能力。此外，监控呼叫阻塞的情况，以确定是否应调整帧错误率目标以进一步增加呼叫容量。无线系统没有经历峰值使用时，语音质量恢复到正常水平。术语“移动用户单元”并不意味着移动单元被限制在移动的车辆上。现有技术包括在固定无线应用中使用移动用户单元作为传统有线电话服务的替代。
