分布式HLR的FE Pool技术浅析

摘要

分布式HLR部署时FE Pool是一种可选的组网方式。在简要介绍分布式HLR的基础上，阐述了FE Pool的工作原理和实现机制，描述了对相关网元的配置需求，并结合N+1的组网方式探讨了FE Pool在实际应用中的优劣势。最后，给出了部署FE Pool的具体建议，指出已采用GT寻址、建设有独立信令监测系统的，可以采用这种建设方式。%FE Pool is an optional deployment mode when constructing distributed HLR. On the basis of the brief description of distributed HLR,it elaborates the implementation principle and implementation mechanism of FE Pool,describes the requirements for the related equipments,and discusses the advantages and disadvantages of FE Pool in applications compared with“N+1”mode. Final y it gives suggestions on deploying FE Pool,points out that this mode is suitable for the network which has apply-ing the technology of GT addressing and using the independent signaling monitoring system.
