Description

technical field [0001] The present invention relates to a system and method for optical access network, in particular to a system and method for moving down the wireless network layer to realize network interconnection. Background technique [0002] The existing optical fiber access network (collectively referred to as FTTx) is divided into FTTH (Fibre To The Home), Fiber To The Building (FTTB, Fiber To The Building) and Fiber To The Curb based on the location of the Optical Network Unit (ONU). (FTTC, Fiber To The Curb) and several other situations. [0003] The official name of OAN (Optical Access Network) is Fiber in the loop (FITL, Fiber in the loop). Due to the high bandwidth of the optical access network, it can better carry out TriplePlay, that is, transmit voice and data at the same time. Business with multimedia video. The optical fiber access network mainly adopts PON (Passive Optical Network, Passive Optical Network) technology, and now there are two mainstream m...

Problems solved by technology

[0014] Since the Node B in the existing protocol stack only handles the physical layer protocol, once the adaptive technology for decision-making using resource management needs to be implemented in the RNC, the network to the terminal must go through two stages: RNC to Node B, and Node B to the terminal , and vice versa, resulting in a longer delay at the Iub interface, and reducing the processing capability of the Node B and the statistical multiplexing rate of the transmission resources of the Iub interface; while the retransmission mechanism of the RLC layer between the RNC and the UE is at the Iub interface In the case of a large delay, the throughput rate will drop; and the outer loop power control algorithm cannot quickly adjust the SIRtarget according to the change of the air interface when the delay of the Iub interface is large; at the same time, the load information of the cell currently relies on NodeB to report periodically , there is an information lag, which causes the load information obtained by the RNC to be out of real time

[0015] It can be seen that the protocol structure that puts all access layers in the RNC will not be suitable for high-speed data transmission. After adopting technologies similar to adaptive coordination and feedback control, this protocol structure cannot guarantee high speed and high efficiency, so it is difficult to Adapt to the needs of high-speed data transmission
