GL Communications Inc., a developer of telecom test and measurement solutions, has announced its enhanced LoCation Services (LCS) architecture in LTE network briefly, and its latest MAPS™ SLs Emulator solution to meet the requirements in location services testing on LTE networks.
Speaking to the press, the CEO of GL Communications Mr. Vijay Kulkarni said, “LTE is similar to GSM/UMTS network and follows a client/server model with the positioning functionality distributed across LTE radio nodes, eNodeBs (eNB), Mobile Management Entity (MME), Evolved-Serving Mobile Location Center (E-SMLC) and Gateway Mobile Location Centre (GMLC).”
Mr. Kulkarni explained “LPP protocol supports hybrid positioning method, in which two or more position methods are used simultaneously to provide accurate measurements. The LTE Positioning Protocols (LPP and LPPa) are carried in LCS-AP PDUs over established SCTP session between an E-SMLC and MME.”
The standard positioning methods used in LTE network are:
- Enhanced Cell-ID (network based, handset assisted)
- OTDOA positioning method (network based, handset assisted)
- UTDOA positioning method (network based)
- A-GNSS based positioning methods (handset based, network-assisted)
