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, 10) 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（10,20,10）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 radio communication system (1600) capable of communicating on at least two radio frequencies has a receiver (202, 206) which receives information addressed to at least one of a plurality of radio receivers (106) on a first radio frequency. A transmitter (104) transmits the information having a control signal therewith to at least one of the plurality of radio receivers (106) on the first radio frequency. A generator (102) generates the control signal for temporarily directing one or more of the plurality of radio receivers to a second radio frequency to receive address and message information. The radio receiver (106) has a receiver (804) which receives information on the first frequency, the information includes the control signal for temporarily directing the radio receiver (106) to the second radio frequency. A decoder (810) decodes the received information, and a frequency synthesizer 1802 directs the radio receiver (106) to receive information on the second radio frequency in response to the control signal. A controller (816) determines when to redirect the radio receiver (106) to return to the first radio frequency.

摘要： A radio communication system (100) has radio receivers (106) assigned to a predetermined one of a plurality of time periods (FRAME 0-127). The radio communication system (100) comprises a transmitter (104) that transmits information during the predetermined time period (FRAME 0-127) assigned to at least one radio receiver (106). A receiver (202, 206) receives information directed to said at least one radio receivers (106), the radio receivers (106) being individually assigned to receive information during at least one of a plurality of predetermined time periods (FRAME 0-127). A monitoring device (1702) monitors a level of traffic associated with each of the predetermined time periods (FRAME 0-127) and a measuring device (1704) measures a level of traffic associated with the at least one radio receiver (106) over the assigned predetermined time period (FRAME 0-127). An identifying device (1708) which is coupled to the measuring device (1704) identifies if the level of traffic associated with the at least one radio receiver (106) exceeds a predetermined threshold value during the assigned predetermined time period (FRAME 0-127). A generator (1732) which is coupled to the measuring device (1706) and to the identifying device (1708) generates a control signal, and the transmitter (1736) transmits the control signal to the at least one radio receiver (106) for reassigning the at least one radio receiver (106). The at least one radio receiver (106) comprises a receiver (804) which receives the control signal and a decoder (810) which is coupled to the receiver (804) which decodes the control signal. A reassigning device (1812) which is coupled to the decoder (810) reassigns the radio receiver (106) from the assigned predetermined time period (FRAME 0-127) to another of the plurality of predetermined time periods (FRAME 0-127) having a lower level of traffic value associated therewith for reducing the level of traffic in the assigned predetermined time period (FRAME 0-127).

摘要： In a battery powered selective call receiver receiving a synchronous signal, a battery saving method extends battery life by optimizing the amount of time the receiver circuit is activated when searching for the signal after previously acquiring synchronization. The battery saving method allows for turning the selective call receiver on without activating the receiver circuit. The receiver circuit is activated at a time later than the energization of the selective call receiver, where the time of activation of the receiver circuit is determined in response to the time passed since synchronization was last acquired and the system signal stability.

摘要： A paging system has a signal for transmitting a variable amount of messages to paging receivers. The signal has a synchronization signal, an address field, an information and a boundary signal indicative of the boundary between the address field and the information field. Each message has addresses which are included within the address field and may have message information which is included in the information field. The information field includes two portions, a first portion having a plurality of packets for holding a predetermined amount of information and a second portion for holding a variable amount of information. If the information associated with a messasge is less than the predetermined amount, the message information is stored in the first portion of the information field. If the message information is greater than the predetermined amount, it is stored in the first and second portions of information field and a vector signal indicating the location of the message information is stored in the first information field. The first portion further includes at least one check signal which provides parity for a plurality of packets. Methods of generating the message signal, receiving a message, displaying a message and conserving power during the reception of a message are described.

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.
