Transmission control method for wireless network and base station

Abstract

The invention relates to the field of wireless communication, and discloses a transmission control method of a wireless network and a base station, which reduces the probability of the base station withdrawing from service and improves the reliability of the base station. In the present invention, at least two Iub interface processing units in the base station are connected to the RNC through the same cable, the cable is Y-shaped, and is divided into a plurality of bifurcated cable joints on the base station side, and is connected to the Iub interface processing units respectively. Among the Iub interface processing units connected to the branch cable joint, one Iub interface processing unit sends uplink data to RNC, and at least one Iub interface processing unit receives downlink data from RNC. A loopback connection signal line is included in the branch cable joint to indicate that the Iub interface processing unit corresponding to the joint is connected to the RNC through the same cable as other Iub interface processing units.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to the Iub interface data backup technology of a base station in a wireless network. Background technique [0002] Wideband Code Division Multiple Access (WCDMA for short), as a representative technology of the third generation mobile communication (The Third Generation, 3G for short), has become increasingly popular. The network side of WCDMA is divided into two parts: Core Network (Core Net, "CN" for short) and Universal Mobile Telecommunications System Terrestrial Radio Access Network (UMTS Terrestrial RadioAccess Network, "UTRAN" for short). Network Controller, referred to as "RNC") and base stations. The interface between the base station and the RNC is called the Iub interface. [0003] With the development of technology, the capacity of WCDMA small base stations is getting higher and higher, and the integration degree is getting higher and higher. A typical small base...

Problems solved by technology

[0005] Although this architecture can increase the capacity of the base station and increase the processing capability of the base station, due to the limitation of the E1 cable interface, only the Iub interface processing unit of the main BBU in a base station can be connected to the RNC, and the redundancy of the Iub interface processing unit cannot be realized. The redundant backup makes the Iub interface processing unit of the main BBU become the critical path of the base station system. Once the Iub interface processing unit of the main BBU fails, the entire base station will be out of service, so that the reliability of the base station cannot be guaranteed
