摘要： A method for synchronizing timestamps in a network (e.g., a wireless ATM network) that includes a control node and a plurality of other nodes that communicate with one another over a common channel mediated by a medium-access control subsystem (e.g., one that uses a reservation-based TDMA protocol). The method includes the steps of sending a first command from the control node, at a first time, then storing a starting timestamp value in a register within the control node and each of the other nodes, in response to the first command, and then sending a second command from the control node, at a second time later than the first time. Each of the other nodes computes the difference between the starting timestamp value and a current timestamp value, and then adds the computed difference to the current timestamp value. In an alternative embodiment, the control node sends a preset command and each of the other nodes presets their respective timestamp to a prescribed initial timestamp value, in response to the preset command. Each of the nodes periodically compares a current timestamp counter value with a prescribed reset value, and upon detecting a coincidence, sets a sync flag latch to indicate that a next timestamp value correction is to be made, in response to a next preset command. Networks that implement the above-described methods are also disclosed.

摘要： A radio communication system where a connection between a controlled radio communication apparatus and a controlling radio communication apparatus is registered. A controlling radio communication apparatus sends vacant slot information indicative of a vacant time division multiplexing time slot to a controlled radio communication apparatus, the controlled radio communication apparatus sends a connection register request signal to the controlling radio communication apparatus using a vacant time division multiplexing time slot based on the vacant slot information, the controlling radio communication apparatus allocates the vacant time division multiplexing time slot to the controlled radio communication apparatus that sent the connection register request signal based on the received connection register request signal, thereby registering the connection of the controlled radio communication apparatus, and the controlled radio communication apparatus sends a control signal using the time division multiplexing time slot allocated by the first radio communication apparatus. With this structure, it is possible to automatically register a connection of a controlled radio communication apparatus.
