Abstract: A method and system determines whether the receiving subscriber unit is also part of a digital wireless telephone system that has compatible vocoding capability. If so, vocoded data is converted into tones that are introduced into a wire-based telephone system for routing to the appropriate receiving digital wireless telephone system. When these tones are received by the receiving digital wireless telephone system, the vocoded data is regenerated based on the tones and then transmitted to the receiving subscriber unit. If the originating and receiving wireless subscriber units are part of the same digital wireless telephone system, the steps of conversion to tones and introduction into the wire-based telephone system may be omitted, and the vocoded data is passed between the two digital wireless telephone systems via an all-digital connection such as an ATM packet network or a wire-based telephone connection where the integrity of digital information is assured.

Abstract: A method and system for processing telephone calls within a digital wireless telephone system is described. During the initiation of a telephone call from a wireless subscriber unit, it is determined whether the receiving subscriber unit is also part of a digital wireless telephone system that has compatible vocoding capability. If so, vocoded data from the digital wireless telephone system is converted into tones that are introduced into a wire based telephone system for routing to the appropriate receiving digital wireless telephone system. When these tones are received by the receiving digital wireless telephone system, the vocoded data is regenerated based on the tones and then transmitted to the receiving subscriber unit. If the originating and receiving wireless subscriber units are part of the same digital wireless telephone system, the steps of conversion to tones and introduction into the wire based telephone system are omitted, and the call is routed completely within that digital wireless telephone system. In another embodiment of the invention, the step of conversion to tones is entirely omitted and the vocoded data is passed between the two digital wireless telephone systems via an all digital connection such as an ATM packet network or a wire based telephone connection where the integrity of digital information is assured.

Abstract: The wireless local loop system employs cellular technology to provide telephone service to fixed telephones of remote stations (20) having otherwise conventional handsets. The remote station (20) emulates a conventional public switched telephone network by providing an artificial dial tone from the handset of the remote station, after the handset is taken off-hook. The artificial dial tone is locally generated (112) by the remote station. The system, however, delays providing the dial tone if the system is busy, i.e. if the system is under a load condition. To this end, the system monitors load levels (20) and transmits signals to the remote stations indicating load conditions. A remote station (20), prior to granting at dial tone to the user, receives the load condition signals, determines whether the system is currently under load (211) and, if so, defers the dial tone (213). Hence, if the system is under a load condition, such that no lines or frequency channels are available, the user is not presented a dial tone until a line or channel becomes available. By deferring the dial tone until a line or channel is available, the wireless local loop system more effectively emulates a PSTN.

Abstract translation: 无线本地环路系统采用蜂窝技术为具有常规手机的远程站的固定电话提供电话服务。 在手机摘机之后，远程站通过从远程站的手机提供人造拨号音来仿真传统的公共交换电话网络。 人工拨号音由远程站本地生成。 然而，如果系统繁忙，即系统处于负载状态，则系统延迟提供拨号音。 为此，系统监视负载水平，并向远程站发送指示负载条件的信号。 在向用户授予拨号音之前，远程站接收负载条件信号，确定系统当前是否处于负载状态，如果是，则延迟拨号音。 因此，如果系统处于负载状态，使得没有线路或频道可用，则在线路或信道变得可用之前，用户不会呈现拨号音。 通过延迟拨号音直到线路或信道可用，无线本地环路系统更有效地模拟PSTN。
