10.1.32 Initial PDP context activation +CIPCA

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

Table 10.1.32-1: +CIPCA parameter command syntax

Command	Possible response(s)
+CIPCA=[<n>[,<AttachWithoutPDN>]]
+CIPCA?	+CIPCA: <n>[,<AttachWithoutPDN>]
+CIPCA=?	+CIPCA: (list of supported <n>s),(list of supported <AttachWithoutPDN>s)

Description

The set command controls whether an initial PDP context (see clause 10.1.0) shall be established automatically following an attach procedure when the UE is attached to GERAN or UTRAN RATs and whether the UE is attached to E-UTRAN with or without a PDN connection.

For 5GS, the command controls whether an initial PDU session shall be established automatically following initial registration.

For <n>≠0, deactivating the last (active) PDP context can lead to a (re)establishment of the initial PDP context. Changing setting of <n> from 0 to 1 will cause an immediate attempt to (re)establish the initial PDP context if no PDP context is active. Changing <n> from 0 to 2 will if not roaming cause an immediate attempt to (re)establish the initial PDP context if no other PDP context is active. The value of <n>=3 applies to E-UTRAN or NG-RAN RATs and does not change the setting of PDP context activation in GERAN or UTRAN RATs. Changing <n> will never cause a PDP context deactivation.

For <AttachWithoutPDN>=1, the EPS Attach is performed without a PDN connection.

NOTE: For this command, the term roaming corresponds to being registered to a VPLMN which is not equivalent to HPLMN or EHPLMN.

The read command returns the current setting of the command.

The test command returns values supported as a compound value.
