In plain words

TS 36.456 is "an introduction to the 3GPP TS 36.45x series of technical specifications", introducing SLm for interconnecting the Evolved Serving Mobile Location Centre (E-SMLC) and Location Measurement Unit (LMU) in E-UTRAN. The overview describes E-UTRAN as having a Radio Network Layer (RNL) and Transport Network Layer, and says logical nodes and interfaces belong to the RNL.

How this page was made

The facts box comes straight from the 3GPP TDoc list and specification archive as indexed by 3GPP Scout. An AI model (GPT-6 Luna) wrote the paragraph and named the source of each sentence. Code checked every quote word for word against the stored source text and every number against the cited source. A second AI model from another company (Claude Opus 5.5) reviewed the paragraph against the same sources. The 3GPP documents themselves govern.
