This document outlines various LTE SIT test scenarios including initial attach procedures with and without valid UE context, mobility procedures like handovers and tracking area updates, detach procedures, loss of coverage, and quality of service testing. It aims to test scenarios for initial attachment, mobility, detachment, handovers between RATs and cells, paging, service requests, and load/capacity of the LTE network.

1. LTE SIT test Scenario's :-
1). Initial Attach with IMSI (UE & MME does'nt have last UE context).
2). Initial Attach with old GUTI (When UE attach to same MME it has attached
last time , but MME does'nt have old UE context stored).
3). UE Attach to new MME that it never attached before & Old MME does'nt have
valid UE conext stored.
4). UE Attach with old GUTI (When UE attach to same MME it has attached before
last time, but MME has last stored UE context.)
5). UE Attach to new MME that it has never attached before & Old MME has UE
context still valid stored.)
6). Network triggered service request (PAGING)
7). UE triggered service request.
8). Detach scenario's (MME initiated explicit detach)
9). UE initiated explicit detach.
10). LTE UE Out of LTE coverage while moving in Connected state.(City A to City
B)
11). MME initaited implicit detach with TAU timer expiry and UE perform initial
Attach using old GUTI.
12).UE performing Intra-frequency cell-Reselection (UE moving from TA1 towards
TA2).
13). Intra-LTE/MME - Intra E-UTRAN Handovers (X2 based handover without SGW
reloaction).
14). Intra-LTE/MME - Intra E-UTRAN Handovers (S1 based handover).
15). E-UTRAN to UTRAN Inter-RAT Handover.
16). LTE QOS (LTE traffic class (QCI) testing ( Verify that LTE traffic is
mapped to appropriate service classes on MSE
according to P-bit marking in uplink and downlink directions in the collocation
scenario)
17). Load / capacity testing
18). Impact and recovery of the system after short IUB Link Break testing on
SIU-02 for 3 minutes.
19). TAU update procedure
