Method and system for interconnecting base station and wired network

Abstract

The invention provides a method and a system for interconnecting a base station and a wired network. The method provided by the invention mainly comprises the following steps of: down-shifting a wireless interface protocol stack of the wired network to the base station; and connecting the base station and the wired network by a passive optical network (PON) or a hybrid fiber coax access network using a data over cable service interface specification (DOCSIS). In the method and the system, a PON / DOCSIS transmission technology serves as the transmission technology of the base station, a novel wireless network transmission way is provided for an operator, and distributed line resources of the conventional PON DOCSIS network can be utilized as much as possible by the construction of a 3G / 2G / worldwide interoperability for microwave access (WiMAX) access network, so the construction cost of the 3G / 2G / WiMAX access network is reduced. In the method and the system, the wireless interface protocol stack is down-shifted to the base station, so a standard lu / lur interface is maximally reutilized, a conventional universal terrestrial radio access network (UTRAN) architecture can be smoothly evolved, the influence of a transmission delay on user quality of service (QoS) is reduced, the transmission rate of the wireless network is increased, and the QoS of a high-speed data service is ensured.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for interconnecting a base station and a wired network. Background technique [0002] Packet networks headed by IP, including public INTERNET / enterprise INTRANET / community broadband access networks, are developing rapidly, featuring low cost, abundant interfaces, large bandwidth, and end-to-end applications. As a wide area network connection technology, IP technology has been popularized around the world, so it also provides operators with new transmission solutions. [0003] The rapid development of digital technology makes the three business networks of computer network, public telecommunication network and cable television network begin to penetrate each other. HFC (fiber optic / coaxial cable hybrid network) has become one of the three-network service carriers that has attracted much attention in the industry because of its good frequency band resources, coverage ...

AI Technical Summary

Problems solved by technology

[0030] 1. The time delay of the lub interface is relatively long, and the processing capability of Node B and the statistical multiplexing rate of the transmission resources of the lub interface are reduced;

[0031] 2. In the case of a large delay in the lub interface, the throughput rate of the retransmission mechanism of the RLC layer between the RNC and UE will decrease;

[0032] 3. When the time delay of the lub interface is relatively large, the outer loop power control algorithm cannot quickly adjust the SIRtarget according to the change of the air interface;

[0033] 4. Cell load information currently relies on NodeB to report periodically. After the information reported by NodeB lags behind, the load information obtained by RNC will not be real-time

[0039] When the transmission bandwidth required by data services continues to increase, if the operator continues to use the E1 / T1 transmission method, the link load between the BS and the base station controller will be relatively large due to the relatively low transmission rate of the E1 / T1 transmission method , cannot meet the rate requirements of high-speed data services, and cannot provide guarantees for the QoS of high-speed data services

At the same time, due to the low charges for data services, it will lead to high costs and low returns, which will seriously affect the profitability of operators.
