9.11.3.29 LADN indication

Taught in 4. Inside TS 24.501, the document at the centre (CT1 — the group that writes what your phone says, overview).

The purpose of the LADN indication information element is to request the network for LADN information for specific LADN DNN(s) or to indicate a request for LADN information.

The LADN indication information element is coded as shown in figure 9.11.3.29.1 and table 9.11.3.29.1.

The LADN indication is a type 6 information element with a minimum length of 3 octets and a maximum length of 811 octets.

The LADN indication information element can contain a minimum of 0 and a maximum of 8 different LADN DNN values.

Value part of the LADN indication information element (octet 4 to h):The value part of the LADN indication information element consists of zero or more LADN DNN values. If the LADN indication information element conveys more than 8 LADN DNN values in this information element, the network shall consider the first 8 LADN DNN values and ignore the remaining octets of the information element.LADN DNN value:LADN DNN value is coded as the length and value part of DNN information element as specified in clause 9.11.2.1B starting with the second octet.
