Taking the 3G / 2G wireless communication network and OAN interconnection as an example, the wireless communication network is a wireless extension of the OAN wired access, and is suitable for fixed wireless, nomadic, portable and mobile access applications, thus providing OAN network operators with the development of wireless networks. an evolutionary path.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to the technical field of interconnection between an optical access network and a wireless communication network. Background technique [0002] Currently, widely used network communication systems include optical network communication systems and wireless communication systems. The two communication systems will be introduced separately below. [0003] The optical network communication system includes an optical fiber access network (collectively referred to as FTTx), and the FTTx can be specifically divided into FTTH (fiber to the home), FTTB (fiber to the building) and FTTC (fiber optic to the side of the road) etc. Due to the high-bandwidth characteristics of the optical fiber access network, that is, FITL (Fiber in the loop), the Triple Play (simultaneous transmission of voice, data and multimedia video) services can be better carried out in the optical network ...

AI Technical Summary

Problems solved by technology

[0028] (1) Due to the need to go through the Iub interface, the corresponding processing time delay is relatively long, and the processing capability of the Node B and the statistical multiplexing rate of the Iub interface transmission resources are reduced;

[0029] (2) The retransmission mechanism of the RLC layer between the RNC and the UE causes the throughput rate of the wireless communication network to decline when there is a large time delay in the Iub interface;

[0030] (3) The outer loop power control algorithm applied in the wireless communication network cannot quickly carry out SIRtarget (target signal-to-interference ratio) adjustment according to changes in the air interface when the Iub interface time delay is large;

[0031] (4) Since the cell load information in the wireless communication network depends on Node B's periodic reporting, the above-mentioned processing process occupies a large amount of Iub interface resources and will cause a delay in reporting the cell load information, thereby making it impossible for the RNC to obtain real-time and accurate cell load information

For example, the interconnection between 3G / 2G wireless communication network and OAN network is a branch of FMC technology. However, there is no technology that can realize the interconnection between the two networks.
