摘要： Communication between a Radio Equipment Control (REC) and a Radio Equipment (RE) in a wireless network uses a Common Public Radio Interface connection. When the Radio Equipment Control and the Radio Equipment are located remote from each other, and are connected by an asymmetric transport network, such as an Optical Transport Network, path delay data is transmitted in the Common Public Radio Interface data frames. This allows the CPRI end nodes to correct for path delay asymmetry using the path delay data.

摘要： A method distributes clock synchronization information within an optical communications network having a plurality of network elements. The method receives an ingress clock synchronization message at a first network element. The ingress clock synchronization message includes a clock synchronization message identifier and a correction field. The clock synchronization message identifier is inserted into an optical channel frame overhead and the ingress clock synchronization message is inserted into an optical channel frame payload. The optical channel frame overhead and the optical channel frame payload are transmitted across the first network element, across the network to a second network element, and across the second network element. A transit time of the clock synchronization message identifier is determined across each of the network elements. At the second network element, the correction field of the ingress clock synchronization message is updated with the transit times to form an egress clock synchronization message.

摘要： In a radio base station apparatus that connects a radio control device and plural radio devices to each other through plural links and transmits and receives data by using a frame, synchronization means calculates a difference between a first reference counter and a second reference counter from first and second transmission values and first and second reception values and corrects a count value of the second reference counter based on the difference so as to make the count value of the second reference counter coincide with a count value of the first reference counter.

摘要： A clock synchronization method, apparatus, and system are provided according to the embodiments of the present invention. The method includes: receiving time information TM1 transmitted by a central office side, in which the time information TM1 is obtained by the central office side by reading a local clock of the central office side when transmission data at a first designated location starts to be transferred, and the local clock of the central office side is synchronous with the Global Positioning System GPS or the Building Integrated Timing Supply BITS; judging whether transmission data at a second designated location starts to be received, if yes, reading a local clock of the Customer Premise Equipment side to obtain time information TS1; and synchronizing clock frequencies of the central office side and the Customer Premise Equipment side according to the time information TM1 and the time information TS1. Therefore, a network reference clock is not used as a working clock to perform the clock synchronization of a DSL system, and therefore the reliability of a DSL link may be independent from the reliability of the network reference clock.

摘要： A method and system for determining timers in an High Level Data Link Control (HDLC) Traffic Manager (HTM) state machine are disclosed. According to one aspect, the invention provides for determining a transit delay between two nodes by sending a first packet having a delay measurement byte to a second node that is on a link between the first node and the second node. The method also includes receiving a second packet with the delay measurement byte from the second node. The delay measurement byte sent by the second node is adjusted by the second node to indicate its receipt by the second node. A measured delay value is determined. The measured delay value is the delay between a time of sending the first packet to the second node and receiving the second packet from the second node. The measured delay value is determined by the hardware of the first node. Upon determining the measured delay value, timer values of the HTM state machine are set based on the measured delay value.
