摘要:
A control system for a wireless telecommunications system, the control system comprising: a server maintaining an object based control structure for controlling the telecommunications system; and an interface to at least one control terminal of the telecommunications system and to at least one client station; wherein the server is responsive to signals from the at least one control terminal and/or to instructions from the at least one client station to generate an operation, the operation being applied to at least one object to effect a change in the at least one object, thereby to control the telecommunications system.
摘要:
A communications protocol interface is arranged at a central station of a telecommunications network and is responsive to a control message received from a network controller in accordance with a first message protocol to transmit the control message in accordance with a second message protocol to subscriber stations and is responsive to a control message received in accordance with the second message protocol to transmit the control message to the network controller in accordance with the first message protocol. The first message protocol is a balanced protocol with the communications protocol converter or the network controller able to initiate an exchange of information. The second message protocol is a master-slave protocol with the communications protocol interface acting as master. The second control message protocol operates over central station bus for communicating with at least one network element in the central station.
摘要:
The receiver (202) of a subscriber terminal (20) compares a code and phase of a master code sequence in the downlink signal (212) to a code and phase of a slave code sequence of the receiver (202). The receiver (202) adjusts the phase of the slave code sequence until a match is obtained with the master code sequence. The downlink signal (212) includes an overhead channel (224) having a power control signal (236), a code synchronization signal (234), and a frame alignment signal (232). A receiver (206) in the central terminal (10) monitors an uplink signal (214) transmitted by the transmitter (204) in the subscriber terminal and provides changes to the code synchronization signal (234) such that the transmitter (204) is synchronized to the receiver (206). The receiver (202) monitors the downlink signal (212) to identify the frame alignment signal (232) and establishes the downlink communication path when two successive frame alignment signals (232) are identified. In an acquisition mode during establishment of the downlink communication path, the downlink signal (212) is transmitted at a high power level and a low transmit rate. In a standby mode after establishment of the downlink communication path, the downlink signal (212) is transmitted at a low power level and a low transmit rate. In a traffic mode upon a request for wireless communication transmission, the downlink signal (212) is transmitted at a high power level and a high transmit rate.
