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 FITL (Fiber in the loop). Due to the high bandwidth of the optical access network, it can better carry out triple play (Triple Play). Simultaneous transmission of voice, data and multimedia video services. The optical fiber access network mainly adopts passive optical network (Passive Optical Network, PON) technology, and now there are two mainstream mature technolog...

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 by resource management is required, it needs to be implemented in the radio network controller RNC. The network to the terminal must go through the RNC to Node B, and Node B to The two phases of the terminal, and vice versa, lead to a longer delay of the Iub interface, and reduce the processing capability of the Node B and the statistical multiplexing rate of the transmission resources of the Iub interface; while the retransmission of the RLC layer between the RNC and the UE When the Iub interface has 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 Iub interface has a large delay; at the same time, the cell load information currently depends on The NodeB reports periodically, and 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
