B.15 SUBSCRIBE method

29.1653GPPInter-IMS Network to Network Interface (NNI)Release 18TS

Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM

As described in table 6.1, the support of SUBSCRIBE method over the non-roaming II-NNI is based on bilateral agreement between the operators.

The table B.15.1 lists the supported header fields within the SUBSCRIBE request.
