Validations ASN.1 Parent Types

This item identifies the high layer user protocol signalled between the mobile station and the network.

Derivation:

Derived values using bits 0-3 of GSM/UMTS item Rate Indication as defined in TS 3GPP 32.005. The 'Source Value' (see Values below) is derived using Other Rate Adaption bits (2 & 3) followed by Rate Adaption bits (0 & 1).

Conditionality:

Must be present within group Basic Service where derivable from the network supplied data (i.e. Rate Indication).

Values:
                UPI                                                         Source Value

* note that H.324 (which is used by circuit switched video telephony) uses the "H.223/H.245" setting at the protocol level.
