In plain words
TS 23.251 covers Network Sharing for GERAN, UTRAN and E-UTRAN, and details the impacts on network architecture. It describes how several core network operators can connect to one shared radio access network. Operators share radio network elements and "may also share the radio resources themselves".

How this page was made
The facts box and the tables come straight from the 3GPP specification archive and CR database 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.
