10.1.60 Request LADN information +CRLADN

27.0073GPPAT command set for User Equipment (UE)Release 18TS

Table 10.1.60-1: +CRLADN action command syntax

Command	Possible response(s)
+CRLADN[=<ladn_dnn>[,<ladn_dnn>[,…]]]	+CME ERROR: <err> +CRLADN: <ladn_information_length>,<ladn_information>
+CRLADN=?

Description

The execution command enables the TE to request LADN information from the network for the specified LADN DNN(s). If the parameter <ladn_dnn> in the execution command is omitted, it indicates a request to the network for LADN information for all LADN(s) available in the current registration area. If <ladn_information_length> has a value of zero and <ladn_information> consists of an empty string, no LADN information is stored on the MT.

The command should be abortable as the LADN information is provided by the network.

Refer clause 9.2 for possible <err> values.

Defined values

<ladn_dnn>: string type; included when the TE wants to request LADN information for specific LADN DNN(s). The <ladn_dnn> is encoded as the value part of the DNN information element in 3GPP TS 24.501 [161], clause 9.11.2.1B. This parameter shall not be subject to conventional character conversion as per +CSCS.

<ladn_information_length>: integer type; indicates the number of octets of the <ladn_information> information element.

If the value is zero, no LADN information is stored on the MT.

<ladn_information>: string type; indicates the LADN information for one or more LADNs, where each LADN consists of a DNN and a tracking area identity list. The <ladn_information> is encoded as the value part of the LADN information information element in 3GPP TS 24.501 [161], clause 9.11.3.30, where each DNN is encoded as the value part of the DNN information element in 3GPP TS 24.501 [161], clause 9.11.2.1B, and each tracking area identity list is encoded as the length and the value part of the 5GS Tracking area identity list information element as specified in clause 9.11.3.9. This parameter shall not be subject to conventional character conversion as per +CSCS.

If the value is an empty string (""), no LADN information is stored on the MT.

Implementation

Optional.
