摘要:

LTE网络通过电路域回落(CSFB)技术为用户提供语音业务。MTRF功能可以解决CSFB边界电路域回落失败的问题,但是MTRF功能部署牵涉网络改造范围。通过对CSFB边界电路域回落问题的分析,在MTRF功能原理研究的基础上,提出了两种MTRF部署方案,应用于不同规模的网络结构。研究结果可以为后续网络建设提供参考借鉴。

Abstract:

The LTE provides voice services for users by CSFB technology. The MTRF function can solve the problems that unsuccessful circuit switched fallback on the edge of CSFB. The deployment of MTRF function involves the range of network remake. By analyzed the problem of unsuccessful circuit switched fallback on the edge of CSFB and studied the principle of MTRF, two deployment proposal were provided. They could be used in different scales of networks. The results could be provided a reference for the follow -up network construction.

Key words: long term evolution, circuit switched fallback, mobile terminating roaming forwarding
