In plain words

RLP stands for Radio Link Protocol. TS 43.010 says its purpose is "for the purpose of implementing error control and retransmission mechanisms in the case of non-transparent low layer capabilities". TS 24.022 specifies RLP for circuit switched data transmission within a PLMN. TS 34.123-3 has a section on handling RLP for CS non-transparent data.

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.
