摘要： A transmitter, having controllable transmission functions is described for transmitting coded message signals to a plurality of portable communications receivers, the coded message signals including and message information interleaved with transmitter control signals synchornized with the message information. The transmitter includes a receiving section for receiving the coded message signals from an input source for transmission. A decoder which couples to the receiving section decodes the synchronized transmitter control signals to derive transmission control signals. A transmitter section, responsive to the transmission control signals, transmits the coded message signals. Additional transmission control signals may also be derived from one or more receiver control signals embedded in the coded message signals.

摘要： A method and apparatus allows sharing first and second signaling formats (400, 708) in a communication system. The first signaling format (400) is synchronous and includes frames (401) transmitted in predetermined frame positions (402). Receivers (110) utilizing the first signaling format (400) are preprogrammed with a base frame position (324) corresponding to one of the predetermined frame positions (402). A system value (326) is transmitted (508) and stored (612) in the receivers (110) for enabling the receivers (110) to monitor(620) at least one frame position (402). The at least one monitored frame position (402)is determined from the preprogrammed base frame position (324) and the system value (326). Frames (401) of the first signaling format (400) are transmitted (508) periodically, and the second signaling format (708) is sent between the periodic transmissions of the first signaling format (400).

摘要： A method and apparatus for reliably delivering messages (200) from a central terminal (102) to a communication receiver (130) in a communication system (100), such as an electronic mail system. The central terminal (102) transmits messages (1300) to the communication receiver (130) and the communication receiver (130) receives transmitted messages (1300) over a first communication medium (122). The communication receiver (130) reconciles messages that it failed to receive over the first communication medium (122) with the central terminal (102) over a second communication medium (152). The reconciliation process between the communication receiver (130) and the central terminal (102) utilizes cyclic redundancy codes (CRCs) transmitted with the messages (1300) to identify the messages (1300) being reconciled.

摘要： In order to allocate frequency channels to transmitter units, the transmitter units are grouped in zones, each zone having one or more transmitter units (10, 20, 30) therein. A system controller (40) calculates a zone priority value which is a function of the zone's message traffic level and message latency. The zone priority value determines the order in which a zone is assigned a frequency channel. A channel priority value is calculated for each channel or sub-channel that can be accessed by the transmitter units (10, 20, 30) in the zone based on a probability of success and a mean quality margin value wherein the priority value of a channel determines the order in which an available channel is considered for assignment to a zone. A proposed channel is assigned to a given zone only if the proposed channel passes a channel quality check. The channel quality check may be based on co-channel and adjacent channel interference values. Alternatively, the channel quality check may be based on a determination of whether a channel proposed for assignment to a given zone is currently in use by another zone that is correlated with the given zone. Zones are merged and divided in order to provide increasing system capacity and better channel quality as the customer demands grow.
摘要翻译：为了向发射机单元分配频率信道，发射机单元被分组在区域中，每个区域中具有一个或多个发射机单元（10,20,30）。系统控制器（40）计算区域优先级值，该区域优先级值是该区域的消息流量级别和消息等待时间的函数。区域优先级值确定区域被分配频率信道的顺序。基于成功的概率和平均质量裕度值，针对可以由区域中的发射机单元（10,20,30）访问的每个信道或子信道的信道优先级值，其中，信道的优先级值确定将可用频道考虑用于分配给某个区域的顺序。只有建议的频道通过频道质量检查，才将所提议的频道分配给给定的频道。信道质量检查可以基于同信道和相邻信道干扰值。或者，信道质量检查可以基于确定被分配给给定区域的信道当前是否正在由与给定区域相关的另一个区域使用。区域被合并和分割，以便随着客户需求的增长提供增加的系统容量和更好的信道质量。

摘要： A data communication receiver (106) is assigned for receiving message signals within one or more message transmission frames (FIG. 3) transmitted in a predetermined sequence. The message signals include address (1604) and message (1608) information, and information (1710) designating one or more additional message transmission frames to which the data communication receiver (106) is responsive for receiving the message signals. The data communication receiver (106) includes a receiver (804) for receiving the message signals, a decoder (830, 816), coupled to the receiver (804), for decoding the address (1604) and designating (1608) information received during the assigned transmission frames, and a memory (850), for storing the message information received which is intended for the data communication receiver (106) during the assigned transmission frames. The decoder (830, 816) is further responsive to the designating (1608) information, for decoding additional address (1604) information received during the one or more additional transmission frames designated by the designating (1608) information, and the memory (850) further stores the message information associated therewith which is received during the one or more additional transmission frames. A display (842) is used to display the stored message information.
