Abstract

The embodiment of the invention provides C-RAN network planning method and device. The method comprises the following steps: acquiring the overlapping coverage of each RRU in an RRU set and other RRUs; marking the other RRUs of which the overlapping coverage is higher than a preset coverage threshold as adjacent RRUs; selecting one RRU from the RRU set as a main RRU; if the distance between the main RRU and the adjacent RRUs in the RRU set and the distance between any two adjacent RRUs meet the preset distance threshold values, combining the main RRU and the adjacent RRUs into a sub-cluster; removing the RRU in the sub-cluster from the RRU set; selecting the next RRU from the rest RRUs in the RRU set as a main RRU until the rest RRUs in the RRU set are not adjacent RRUs of other RRUs; according to the embodiment of the invention, the adjacent relation of each RRU in the RRU set is obtained, and the RRU in the RRU set is divided into the plurality of sub-clusters by combining the distance between the RRU set and the RRU set, so that the planning of the BBU is facilitated, the anti-interference effect between the RRUs is further reduced, and the spectrum efficiency function is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of wireless communication, and in particular to a C-RAN network planning method and device. Background technique [0002] The centralized radio access network (Centralized Radio Access Network, C-RAN) is a new radio access network framework proposed according to the current network conditions and the trend of technological progress. C-RAN is a green wireless access network architecture (Clean system) based on centralized processing (Centralized Processing), collaborative radio (Collaborative Radio) and real-time cloud computing architecture (Real-time CloudInfrastructure). Its essence is to achieve low cost, high bandwidth and flexible operation by reducing the number of base station equipment rooms, reducing energy consumption, adopting collaborative and virtualization technologies, realizing resource sharing and dynamic scheduling, and improving spectrum efficiency. The network a...
