| Because the optimization of transmission networks can't receive obvious benefits as wireless networks, always be ignored by carriers. Now the carriers judge the quality of the transmission networks just by a simple way: whether it can provide the circuit. Don't consider the optimization of the current transmission networks. When the networks can't offer enough capability, most carriers always think of building, not optimizing. This paper based on the original version of the transmission network of CMBJ (China Mobile Group Beijing Co., Ltd.), we introduce some factors which can be optimized in the transmission network construction process of CMBJ from different points. Such as: equipment choosing, network organization mode, distribution of circuits, management of networks. Meanwhile, we provide some plan and optimization suggestions for the construction of local transmission networks which can provide good services to mobile business.This paper does some researches on network organization mode, equipment updating, and construction of optical networks, based on the current transmission networks of CMBJ. From these researches we can see that there are some shortages in the transmission networks and the operation goal. At the end, we provide some optimization suggestions for the equipment, network mode, and the network management system. Do a little contribution to construct a Golden transmission network of CMBJ. |
