When a UE registers with only a TMSI, we obviously can't store an IMSI. However, since we're so far never *using* the list of UEs in osmo-hnbgw, we might as well just accept the TMSI registration and carry on as usual. This is particularly helpful with an ip.access nano3G femto cell, as it tends to send UE registrations with a TMSI+LAI identification instead of an IMSI when the subscriber is known. This causes timeouts of several minutes until a UE registration switches back to IMSI. When simply accepting the TMSI in osmo-hngw, no problems are apparent in our current code state. We could use the subscriber list during paging, but on the other hand, it doesn't hurt to anyway always page to all HNBs connected to osmo-hnbgw. The paging procedure does include a page-to-all-HNBs in case the first HNB paging fails. However, since we're now failing to record UEs that register by TMSI, we must be aware that trying to page such UE on only its last seen HNB will fail; it is plainly missing in the list. http://cgit.osmocom.org/osmo-iuh/commit/?id=0c35d83fbd19f841d84c3218635c5ac… commit 0c35d83fbd19f841d84c3218635c5ac9fdbf54d1 Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Mon Apr 25 14:55:35 2016 +0200 UE Register with TMSI: reply with a Register Reject When receiving a UE Register Request with TMSI and no IMSI, compose a Register Reject with the same UE Identity and send. The accepting function expects a ue_context argument and composes the message from the IMSI found there. This new rejection message cannot rely on a ue_context struct and hence uses the asn1 uE_Identity directly. http://cgit.osmocom.org/osmo-iuh/commit/?id=2860445326f4a23e382cb349d4e7b52… commit 2860445326f4a23e382cb349d4e7b52f44d8a7a1 Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Mon Apr 25 15:21:09 2016 +0200 RAB parameters: add Extended Max Bitrate This IE is seen in a "real life" pcap of hNodeB operation. We did not need it so far, but add it to test the ip.access nano3G. Comment from the future: the ip.access nano3G rebooted upon RAB Assignment Request, and after adding/tweaking some IEs it stopped rebooting. This is one of the changes that fixed the reboot issue. The changes have been tested incrementally until reboots vanished, but it's not clear/hasn't been tested whether omitting this change alone will cause reboots to re-appear. http://cgit.osmocom.org/osmo-iuh/commit/?id=3b8e4d9675c9e36c19e64256da3658e… commit 3b8e4d9675c9e36c19e64256da3658ed4347287f Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Mon Apr 25 15:17:25 2016 +0200 RAB parameters: tweak the Allocation Or Retention Priority These values are seen in a "real life" pcap from hNodeB operation.
