巧解900MHzLTE-FDD与GSM共模组网的频率规划难题

An Intelligent Solution to the Frequency Plannning Problem of 900MHz LTEFDD and GSM Common-mode Networking

网络容量、网络覆盖、服务质量是互相制约关系,如何在网络覆盖、服务质量保持不变时,进行LTE-FDD和GSM网络的Band 8的频率规划是一个难题。介绍了业务量与频率资源需求的评估方法。在LTE-FDD使用10 MHz、5 MHz、3 MHz组网时,GSM 900 MHz共站允许的最大载频数、单小区允许最大承载TCH话务量、数据流量的计算方法、GSM高配置站点的减容评估方法和利用PDE提高PDCH承载效率减少PDCH数量的处理措施,以及LTE-FDD与GSM共模组网的质量评估方法。

The network capacity, network coverage, quality of service is interrelated. When network coverage, quality of service remains, this a problem on how to plan frequency in the LTE FDD and GSM network in Band 8. This describes the assessment methodology frequency resource requirements, When IOMHz, 5MHz, 3 MHz band is used for LTE-FDD network, How to calculate the maximum allowable number of cartier frequency in a GSM base station, and how to calculate the maximum allowable TCH traffic and throughput in a GSM cell. A reduction assessment methods in GSM base sites, the actions by using PDE improve efficiency to reduce the PDCH amount, and the Network quality assessment methods of LTE-FDD and GSM common-mode networking.
