SRNS Relocation Introduction Package

Before VP services are handed over to the 2G system, this feature enables the fallback of video telephony to speech to ensure continuous calls

SRNS Relocation (UE Not Involved)

SRNS Relocation with Hard Handover

SRNS Relocation with Cell/URA Update

Lossless SRNS Relocation

Benefits:

Reduce the bandwidth occupied by the Iur interface.

Reduce the transmission delay of user plane.

Get the parameters of cell-level algorithms to optimize the performances.

Ensure that communications are not interrupted when the UE moves to the coverage area of another RNC while the Iur interface is not available.

Help to keep the integrity and continuity of the data transfer, and improve the best effort service performance during the SRNS relocation procedure.

SRNS relocation based on delay optimization

SRNS relocation based on transmission optimization

documentation very useful for my job

Good Document

Sound good.......very useful

useful document, thanks
