GL Communications Inc., announced today its enhanced Mobile Application Part (MAP) Protocol Emulator that now supports LoCation Services (LCS) as per 3GPP TS 23.271 specifications.

Speaking to the press, Mr. Karthik Ramalingam, a Senior Manager for product development of the company said, “Accurate location services is playing a vital role in many public operations such as emergency services, vehicle tracking, stolen assets tracking, advertising, and social networking. Location based services provide information about the geographic location of Mobile Equipment (ME), which rely upon LoCation Service (LCS). “

He added, “MAP network now includes LoCation Services (LCS) specific elements and entities, their functionalities, interfaces, as well as communication messages, necessary to implement the positioning functionality in a cellular network. LCS architecture follows a client/server model with the Gateway Mobile Location Centre (GMLC) acting as the server providing information to External LCS Clients.”

Mr.Ramalingam further explained, “GL’s MAPS™ MAP IP signalling emulator is enhanced to simulate LCS procedures over Lg and Lh interfaces using MAP signalling protocol. Supported LCS procedures include Provide Subscriber Location, Subscriber Location Report, and Routing Info for LCS respectively, as per 3GPP TS 23.271 specifications.

The Lg and Lh interfaces enable LCS in the GPRS/UMTS to provide support for specialized mobile location services for operators, subscribers, and third-party service providers.

MS initiated Location Report Procedure is supported over Lg Interface between GMLC and MSC and Network Initiated Location Retrieval Procedure over Lh Interface between GMLC and HLR.

The Lg interface implements the following Mobile Application Services:MAP-Provide-Subscriber-Location and MAP-Subscriber-Location-Report.

The Lh interface implements the following Mobile Application Services: MAP-SEND-ROUTING-INFO-FOR-LCS, used to retrieve the routing information.”

He further added, “Other primary facilities provided by GL’s MAP emulator are “Mobility Services”, "Operation and Maintenance", "Call Routing and Roaming", "Subscription Information", "Short Message Service", “Packet Data Protocol (PDP) services for GPRS”, “Supplementary Services” and many more.”
