Tree-shaped optical fiber distribution system whole network upgrade control method and device

Abstract

The embodiment of the invention provides a tree-shaped optical fiber distribution system whole network upgrading control method and device. The method comprises the steps that an upgrading data packetis issued to target equipment through a special upgrading data interaction channel; and if it is determined that the response information of the target device for the upgrade data packet is not received within the first time threshold, a data communication link state with the target equipment is monitored, and the target equipment is upgraded according to the data communication link state. According to the tree-shaped optical fiber distribution system whole network upgrade control method and device provided by the embodiment of the invention, upgrade is carried out through the special upgradedata interaction channel, the upgrade is independent from a normal service channel and does not influence each other, and independent operation of an upgrade process and a service process is ensured.And when upgrading is abnormal, the target equipment is upgraded again by monitoring the state of the data communication link between the MU and the target equipment, so that manual on-site upgradingis avoided, whole-network synchronous upgrading can be realized, the upgrading efficiency is high, the operation is simple and convenient, and the success rate is high.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to a method and device for controlling network-wide upgrade of a tree-shaped optical fiber distribution system. Background technique [0002] With the changes in the characteristics of modern buildings, the increasingly dense high-rise reinforced concrete building structures have brought a great impact on the indoor signal coverage of traditional repeaters. The depth and quality of signal coverage need to be improved urgently. The unit MU directly drags and hangs multiple high-power remote RRU devices through optical fibers. The wide-range and coarse coverage mode is difficult to meet the needs of users in the actual use environment. Therefore, as the mainstream digital distributed optical fiber communication system coverage The method has gradually evolved into that each MU pulls multiple extension equipment EUs through optical fibers, and the EU pulls multiple ...

Problems solved by technology

The existing upgrade solutions are all based on physical devices connected by Ethernet. Various upgrade applications developed on the basis of equipment networking and IP protocol are very rich, there are many implementation methods, and the upgrade methods are also convenient and quick. However, for the tree-shaped optical fiber distribution system For MU, EU and RU devices, due to their limited software and hardware resources and cost considerations, especially the transmission interface of some module-level RU devices is not an Ethernet interface, the upgrade management method cannot be as convenient as that of ordinary network devices. Both the EU and RU devices are placed outdoors, and the distribution environment is complex, so it is not easy to directly connect and upgrade. All device management is performed at the MU side by relying on optical fiber links to achieve simple data communication, including the upgrade of the EU and RU by the MU. In most cases, it can only rely on After uploading the required upgrade package to the MU, the MU will send the upgrade package to the EU step by step, and then the EU will send the upgrade package to the RU to complete the upgrade

[0004] The upgrade process in the prior art is complicated, time-consuming and labor-intensive. If the upgrade is abnormal, manpower is still required to go to the site to guard the upgrade. Therefore, it is urgent to propose an efficient, stable and flexible upgrade solution to meet this type of tree-shaped optical fiber distribution system. equipment upgrade needs
