from TS 24.501 subclause 6.4.1.5
The maximum number of PDU sessions which a UE can establish in a PLMN is limited by whichever is the lowest of: the maximum number of PDU session IDs allowed by the protocol (as specified in 3GPP TS 24.007 [11] subclause 11.2.3.1b), the PLMN's maximum number of PDU sessions and the UE's implementation-specific maximum number of PDU sessions.
As per TS 24.007 [11] subclause 11.2.3.1b, The range of PDU session ID is 1-15, does this mean a maximum of 15 PDU sessions?
