Method and apparatus for generating and distributing an internal clock for radio network controller |
摘要 |
The present invention provides a method for generating an internal clock in a radio network controller and a relevant transmission processing board. The transmission processing board comprises: a clock signal selector for extracting a clock signal from a synchronous/asynchronous line connected with a core network when said transmission processing board functions as a master transmission processing board, or for obtaining a clock signal from a clock bus of a sub-rack in which said transmission processing board is located when said transmission processing board functions as a slave transmission processing board; a phase-locked loop for generating a reference transmission clock based on the clock signal extracted or obtained by said clock signal selector; and a clock driver for transmitting the generated reference transmission clock to the clock bus of the sub-rack in which said transmission processing board is located when said transmission processing board functions as a master transmission processing board. According to the present invention, it is not necessary to provide a dedicated clock board, which in turn reduces the types of boards and lowers the complexity of connection lines. <IMAGE> |
