The LCS Test Case
Landslide Location services is able to simulate SLg messages between GMLC and MME interface, SLh interface between GMLC and HSS and SLs messages between the E-SMLC and the MME.
Slg provides the Slg interface tab in LCS Node/Nodal test cases for EPC location services between GMLC and MME.
Slh provides the Slh interface tab in LCS Node/Nodal test case for GMLC to request routing information from the HSS/HLR. The SLh interface is defined between the Gateway Mobile Location Center (GMLC) and the Home Subscriber Server (HSS) to allow the GMLC to request routing information from the HLR or HSS.
Sls provides the Sls interface tab in LCS Node/Nodal and MME Node/Nodal test cases for E-SMLC to provide location information to the MME. The SLs interface is defined between the Evolved Serving Mobile Location Center (E-SMLC) and the MME (Mobility Management Entity) .
In order to support back to back test case we provide LCS Node/ Nodal.
LCS (Location Services) is specified in 3GPP TS 23.271 and SLs interface in 3GPP TS 29.171.
With these test cases, you can :
Slg interface tab in LCS Node/Nodal test cases for EPC location services between GMLC and MME. GMLC initiate the EPC location services protocol by sending "Provide-Location-Request" (PLR) to MME. MME will respond with PLA. When MME wants to implicitly report the subscriber location MME, it will send Subscriber Location report to GMLC (LRR), which is acknowledged by GMLC via LRA. PLR (GMLC Node) and LR (GMLC Nodal) interface tabs - Available to initiate request for Location Services
Selecting Slh provides the Slh interface tab in HSS Node/Nodal test case for GMLC to request routing information from the HSS/HLR. LCS Node initiates the Routing Information Request (RIR) by sending it to HSS. HSS (LCS Nodal) responds with RIA.RIR (Routing information Request) and RIA (Routing Information Answer) interface tabs - Available to initiate request for Routing Information.
Selecting Sls provides the Sls interface tab in LCS Node/Nodal test case and MME Node/Nodal test case for MME to initiate a Location request from the E-SMLC. The E-SMLC performs a positioning procedure and returns the resulting location information to the MME.
Selecting E2 provides the E2 interface tab in LCS Node and PSAP Node test cases. LCS Node test case can be used to emulate a GMLC instance and an E2 interface for interacting with an external PSAP. Per reference docs : NENA-05-001 December 2003 (NENA Standard for the Implementation of the Wireless Emergency Service Protocol E2 Interface) and J-STD-036-A - Enhanced Wireless 9-1-1 Phase 2.
