From 10db2817e5ce76eebd61dd6b607a6dfad57fa417 Mon Sep 17 00:00:00 2001 From: Oliver Smith Date: Fri, 14 Dec 2018 16:14:34 +0100 Subject: GSUP: add CHECK-IMEI message Implement necessary messages for Procedure Check_IMEI_VLR (TS 23.018 Chapter 7.1.2.9). This lets the VLR ask the EIR to check if an IMEI is valid. In the Osmocom stack, we don't have an EIR and this request will be handled by the HLR. We will be able to store the IMEI in the HLR as side-effect (OS#2541). This is roughly based on TS 29.002 8.7.1 MAP_CHECK_IMEI service, but only implements the bare minimum required IEs (imei and imei_result).
