Rohde & Schwarz CMW500 LTE and EV-DO Handover Application Note

About this manual

The document describes network handover mechanisms between LTE and EV-DO technologies. It details two main architectures: optimized handover, which allows seamless switching with minimal interruption (under 300ms), and non-optimized handover, which is simpler but causes longer service disruption.

It outlines the specific steps for active handovers from LTE to EV-DO, including pre-registration, preparation, and execution phases involving interfaces like S101 and S103. The text also covers cell reselection procedures and the necessary changes required on mobile User Equipment (UE) to support these new protocols. This manual is written in Chinese.

Frequently asked questions

What is the maximum interference time for optimized network switching?

The interference time should not exceed 300 milliseconds.

Which interface ensures no data loss during switching between the two network technologies?

The S103 interface ensures there is no data loss.

Which Rohde & Schwarz device supports testing for both optimized and non-optimized handovers?

The R&S CMW500 broadband wireless network analyzer supports these tests.
