摘要： A non-real time messaging system (200) for targeting messages to a subscriber unit (222) comprises a synchronized profile of where a subscriber unit should be located (a predetermined base transmission area for transmission of messages to the subscriber unit) maintained between a controller (212) and the subscriber unit. The subscriber unit detects when the subscriber unit is not within the receiving range of a predetermined base transmission area, informs the controller and the controller directs subsequent transmissions to an area identified by the subscriber unit and otherwise transmits subsequent messages to the predetermined base transmission area. The system further includes a plurality of base receivers (217) coupled to the controller for receiving transmissions from the subscriber units and allowing the controller to detect when the subscriber unit is not within the receiving range of a predetermined base transmission area.

摘要： A two-way communication system is used for performing dynamic channel control. The two-way communication system comprises a base transceiver (102) and a plurality of selective call transceivers (122). The base transceiver (102) includes a plurality of base stations (116) controlled by a controller (112). The base transceiver (102) transmits query signals to the selective call transceivers (122) to prompt communication. The selective call transceivers (122) measure the signal quality of signals transmitted by the two-way communication system and transmit in return signal quality measurement data to the base transceiver (102) for analysis. The base transceiver (102) dynamically adjusts the signal quality of signals to be received by the selective call transceivers (122) in order to substantially reduce the noise interference that the selective call transceivers (122) experience.

摘要： A portable subscriber unit (104) monitors (602) a signal fading rate in an outbound channel from a base station (102), and transmits a message. The portable subscriber unit transmits (606) the message once on an inbound channel in response to the signal fading rate in the outbound channel being less than a predetermined value. The portable subscriber unit transmits (608) the message more than once in response to the signal fading rate in the outbound channel being greater than or equal to the predetermined value.

摘要： An etiquette controller (112) in a transmitter (14) in a first radio frequency (RF) communications system (10) enables radio frequency communications in a frequency bandwidth shared with heterogeneous RF communication systems (15). The etiquette controller (112) monitors the first RF signals in an isochronous frequency channel in a sub-band of the shared frequency bandwidth to determine whether (124) a frequency channel is free or whether (130, 136) the frequency channel comprises a communication channel which is free. In addition, the etiquette controller (112) causes the RF transceiver (102) to transmit (148) a channel relinquishment signal, monitors (150) the isochronous frequency channel for a predetermined monitoring time, and determines (152) whether the isochronous frequency channel is then free for the channel access.

摘要： A method and apparatus is used for transmitting an outbound message in a two-way messaging system having a plurality of cells employing frequency reuse. The outbound message is transmitted to a selective call transceiver (122) utilizing a first frequency reuse plan (312). The two-way messaging system awaits a positive acknowledgment (316, 318) from the selective call transceiver (122) confirming that the outbound message was received with an acceptable quality. The two-way messaging system retransmits the outbound message to the selective call transceiver (122) utilizing a second frequency reuse plan (332), in response to receiving a negative acknowledgment and also in response to failing to receive any acknowledgment within a predetermined time after transmitting the outbound message.

摘要： A two-way selective call communication system (FIG. 1) controls transmissions in a dominant cell (504) of a plurality of cells (502, 504) utilizing a common radio frequency for sending messages (408). The dominant cell carries significantly greater traffic than any other cell of the plurality of cells. A controller (112) groups (808, 906), into a first time period (708), the transmissions of non-dominant cell messages which interfere with the transmissions of dominant cell messages. The controller then determines a subset of the dominant cell messages that require a higher signal-to-interference ratio than available in the dominant cell during the first time period. The controller then transmits (908) the subset during a second time period (710) different from the first time period.

摘要： Nodes (103a-d, 105, 107, 109a-c, 111a-c) in an ad hoc communication network are coordinated. The network includes the node (111b) and one or more neighbor nodes (103a-d, 105, 107, 109a-c, 111a,c). The node (111b) can sleep in a low duty cycle. Further, the node (111b) can awaken, responsive to a schedule; and register with a cluster head (101); listen for one or more neighbors, wherein the at least one neighbor can be active (103a-d, 105, 107) or idle (109a-c, 111a,c); and/or listen for one or more requests from the cluster head (101) or active neighbor(s) (103a-d, 105, 107). Responsive to the request(s), the idle node (111b) can become active on a communication link.

摘要： Techniques are provided for allowing a node (300) in an ad hoc network to deterministically decide whether to relay broadcast information to another node in the ad hoc network. The node (300) receives broadcast information and measures received signal strength (RSS) of the broadcast information. The node (300) may determine if the measured RSS is below a low threshold, and if so, can relay the broadcast information to neighbor nodes. Otherwise, the node (300) can also determine if the measured RSS is above a high threshold, and if not, wait for a waiting period before relaying the broadcast information to the neighbor nodes. The node (300) may dynamically adjust the low threshold by decreasing the low threshold as the number of neighbor nodes increases and may dynamically adjust the high threshold by increasing the high threshold as the number of neighbor nodes decreases.
摘要翻译： 提供了允许自组织网络中的节点（300）确定地决定是否将广播信息中继到自组织网络中的另一个节点的技术。 节点（300）接收广播信息并测量广播信息的接收信号强度（RSS）。 节点（300）可以确定测量的RSS是否低于低阈值，如果是，则可以将广播信息中继到相邻节点。 否则，节点（300）还可以确定测量的RSS是否高于高阈值，如果不是，则等待等待周期，然后再将广播信息中继到相邻节点。 节点（300）可以通过随着邻居节点数量的增加而减小低阈值来动态地调整低阈值，并且可以随着邻居节点数的增加而增加高阈值来动态地调整高阈值。

摘要： A technique is used in a data terminal (110, 160) that encodes and decodes a data packet that is transmitted in a link of a frequency hopping system. During encoding, an information portion of the data packet is determined for transmission, a transmit redundancy check code is generated over the information portion and an identifier using a predetermined redundancy check code generator, and the data packet is generated to include the transmit redundancy check code and the information portion, but exclude the identifier. During decoding, the information portion and a received redundancy check code of the received data packet are determined, a calculated redundancy check code is generated over the information portion and the identifier, using the predetermined redundancy check code generator, and the information portion is rejected when the received redundancy check code does not match the calculated redundancy check code.
