SRB-Identity: the RRC information element in TS 38.331
At a glance
- Specification
- 3GPP TS 38.331 V19.4.0, clause 6.3.2
- Structure
- A single INTEGER value
- Used in
- RLC-BearerConfig, RadioBearerConfig, SL-ConfigDedicatedNR
In plain words
SRB-Identity identifies a Signalling Radio Bearer (SRB) used by a UE, as TS 38.331 V19.4.0 clause 6.3.2 says: "The IE SRB-Identity is used to identify a Signalling Radio Bearer (SRB) used by a UE.". Its ASN.1 structure in that version is a single INTEGER value with no fields, so the IE identifies the bearer rather than containing multiple fields. That version references SRB-Identity in RLC-BearerConfig, RadioBearerConfig, and SL-ConfigDedicatedNR.

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.
