Introduction

PDN connections setup: Main service connection(Main A10) is responsible for creating the default PDN connection. aux SoType = 59 is responsible for creating additional PDN connections. If you configure an “Aux SoType = 59” on Landslide GUI, it’s not a real Aux connection, it just represents an addtionational PDN connection. Its corresponding APN indicates which PDN it connects to.If you configure an “Aux SoType = 67” on Landslide GUI, it’s a real Aux Connection. Its corresponding APN indicates which PDN this Aux is related with.If configuring total N PDN connections including main service connection and M real auxiliary service connection, you should set the aux number to N-1+M.In this test case, I take 2 PDN, and 3 real auxiliary for example.

Presupposition

In successor pages, we use main for short of main service connection, Aux for short of auxiliary service connection.I just show the difference between Multi-PDN and Multi-Aux with normal eHRPD case. Other parts are configured the same with normal eHRPD case.

• We should assign N PDN on the first N connections.

• The Item in “service instance APN Assignments” is associated with that in “Service Instance Setting”. That is: • Main -> P0 • Aux-1 -> P1• Aux-2 -> P2• Aux-3 -> P3• Aux-4 -> P4
