Editing My 33.128 Notes (section)

====== 6.2.2A.2.3	Transmission to the ICF ======
When activated (see clause 5.2.7), the IEF shall establish a TLS connection to the ICF as given over LI_XEM1. If the IEF fails to establish a TLS connection, it shall report an error over LI_XEM1 using the error reporting mechanisms described in ETSI TS 103 221-1 and attempt to reconnect after a configurable period of time.

When a record has been generated as described in clause 6.2.2A.2.2, the IEF shall encode the IEFAssociationRecord or IEFDeassociationRecord as a BER-encoded IEFMessage structure, following the ASN.1 schema given in Annex F, and transmit it to the ICF over the established TLS connection.

The IEF may transmit a keepalive request using the keepalive record defined in Annex F. Upon receiving a keepalive request, the ICF shall respond with a keepaliveResponse record containing the same sequence number used in the request. The circumstances under which the IEF transmits keepalive requests is out of scope of the 33.128 V18.0.0 (2022-06) document.
