GL Announces Simulation of Location Based Services in LTE Networks
GL Communications Inc., announced today the release of its LoCation Services (LCS) Test Suite to support simulation of location based services in LTE networks.
- (1888PressRelease) March 29, 2017 - Gaithersburg, Maryland - GL Communications Inc., announced today the release of its LoCation Services (LCS) Test Suite to support simulation of location based services in LTE networks.
Speaking to the press, Mr. Karthik Ramalingam, a Senior Manager for Product Development of the company said, "The LCS architecture in LTE is similar to GSM/UMTS network, and follows a client/server model with the positioning functionality distributed across LTE radio nodes, eNodeBs, Mobile Management Entity (MME), Evolved-Serving Mobile Location Center (E-SMLC) and Gateway Mobile Location Centre (GMLC)."
He added, "LTE operates two positioning protocols via the radio network: LTE Positioning Protocol (LPP) and LPP Annex (LPPa). 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."
Mr. Ramalingam further explained, "GL's MAPS™ LCS test suite comprises of multiple products that work in tandem to support simulation of location services on LTE networks.
To support simulation of location services in LTE network, the MAPS™ SLs interface emulator supports LCS procedures over SLs interface between MME and E-SMLC using LCS-AP signalling protocol. Also, MAPS™ Diameter is enhanced to simulate LCS procedures over SLg, and SLh interfaces using Diameter protocol.
GL's MAPS™ supports simulation of different Positioning methods and Position Estimation of a Mobile Stations (MS) in universal coordinates. The estimate is expressed in terms of the geographical shapes and is composed of the type of shape plus the encoding of the shape itself. The Location Estimate parameters such as Type of Shape and coordinates can be input through conventional user profiles or can be fetched from a CSV file every time it sends the location estimate to the client. This selection is to be made by the user.
If the selection is 'Profile' all the values present in the particular profile will be sent in the message response. If the selection is made as 'CSV', an entry from the csv file is loaded and all the values from the fetched record will be sent in the message response.
These coordinates indicate different position of MS at different intervals of time and report is sent either periodically at specified time duration or at once when requested."
