Release Change Reference, StarOS Release 17 ▄
307
With this enhancement, the MME will allow operators to configure adjacency lists as TAI Lists, thus reducing the
Tracking Area Updates (TAU) received by MME. This feature enables the MME to send configured customized TAI
List in ATTACH_ACCEPT/TAU_ACCEPT when a request is received from the custom or border TAIs.
Tracking Area Updates (TAU) received by MME. This feature enables the MME to send configured customized TAI
List in ATTACH_ACCEPT/TAU_ACCEPT when a request is received from the custom or border TAIs.
The reduced TAU results in less signaling load on the MME and better operational efficiency.
