Base station ring group network transmission detection method

Abstract

The invention forwards a method for detecting the transmitting the ring network of the base station, which includes the following steps. The controller of the base station sends a massage of transmission-detection. If receiving the massage, the station shows that the transmission of uplink works in a normal state, and the updated massage is sent to the downlink equipment. If not receiving the massage in the preset time, the station triggers a downlink level transmission-detection and sets the working state of uplink to be unmoral. This invention runs a loop detection and anti-loop detection simultaneously in the ring network, and each base station can obtains the transmission link status simultaneously, to avoid inconsistent transmitting massages by different station. The link detection does not involve a number of logic levels, thus the detection speed is very rapid.

Description

technical field [0001] The invention relates to a mobile communication network, in particular to a base station ring network transmission detection technology. Background technique [0002] There are four main networking modes of mobile communication system base stations: star, chain, tree and ring. The star networking method is relatively simple to implement and has high reliability, but it occupies more ports and transmission resources; the chain networking method can save transmission and port resources, but requires high reliability of transmission resources. chain, multiple base stations will be affected and cannot provide services; the chain type is actually a special tree-type network, which can save ports and transmission resources, but reliability cannot be guaranteed. [0003] In some special occasions, when the cellular system serves occasions with high security or reliability requirements, it is required that the system can provide services without interruption,...

Problems solved by technology

[0006] 1. The OML link is implemented by a multi-layer communication protocol between entities in the communication system. It takes time to transmit information between the internal layers of the entity, and most of the information transmitted on the OML link is operation and maintenance information rather than link detection information, so the transmission is interrupted. Chain detection is slow and inefficient;

[0007] 2. Each base station and the base station controller have their own independent OML link, and each link is performing link disconnection detection. Due to the complexity of the link entity state machine, each OML link when the transmission link is disconnected The timing of the detected link disconnection is different;

[0008] 3. The OML link carries all the operation and maintenance information of the relevant base stations. If the OML link is broken, it means that the base station loses contact with the base station controller. Therefore, it is difficult to use the OML link for transmission link detection to be independent of the base station operation and maintenance function;

[0009] 4. There is a close relationship between the OML link and the base station business. For example, base station configuration and cell attributes are downloaded from the base station controller to the base station through OML, and there is also a close relationship between the transmission link and the base station business; therefore, OML is used Link detection and transmission disconnection are difficult to be independent of business
