From 03ded913ad60cafa9f79443c845cd01fe8a0c929 Mon Sep 17 00:00:00 2001 From: Oliver Smith Date: Thu, 2 May 2019 10:40:50 +0200 Subject: [PATCH] vty: make retrieve-imeisv-early configurable Prepare for Rhizomatica's subscriber on demand use case, in which the network access is disabled by default for new subscribers, but the IMEI is required in the HLR to find out which user has which IMSI. Due to the network access being disabled, the location update request towards the HLR fails and the MS gets rejected, so we need to get the IMEI early.
