Attention is currently required from: pespin. Hello Jenkins Builder, pespin, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-bts/+/33829 to look at the new patch set (#3). Change subject: pcu_sock: forward downlink IMMEDAITE ASSIGNMENT with no IMSI to AGCH ...................................................................... pcu_sock: forward downlink IMMEDAITE ASSIGNMENT with no IMSI to AGCH When the SAPI PCU_IF_SAPI_PCH_DT is used, messages should include an IMSI. However, there may be situations in the PCU where no IMSI is available when sending an IMMEDIATE ASSIGNMENT through the PCH. In those cases we cannot calculate the paging group. Even though it would work to use the paging group 0, it is more appropriate to send the IMMEDIATE ASSIGNMENT through the AGCH then. As a background information to this it should be noted that this works because the IMSI is commonly not known during a GMM ATTACH REQUEST. In this phase the MS is in non-DRX mode, which means that it listens on all CCCH blocks (PCH and AGCH) See also: 3gpp TS 44.060, section 5.5.1.5 and 3gpp TS 45.002, section 6.5.3, 6.5.6 Related: OS#6097 Change-Id: Iaa3e5cdcf86578821e149b3e23482a0bcee19f7b --- M include/osmo-bts/bts.h M src/common/bts.c M src/common/pcu_sock.c 3 files changed, 69 insertions(+), 4 deletions(-) git pull ssh://gerrit.osmocom.org:29418/osmo-bts refs/changes/29/33829/3 -- To view, visit https://gerrit.osmocom.org/c/osmo-bts/+/33829 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: osmo-bts Gerrit-Branch: master Gerrit-Change-Id: Iaa3e5cdcf86578821e149b3e23482a0bcee19f7b Gerrit-Change-Number: 33829 Gerrit-PatchSet: 3 Gerrit-Owner: dexter <pmaier(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: pespin <pespin(a)sysmocom.de> Gerrit-Attention: pespin <pespin(a)sysmocom.de> Gerrit-MessageType: newpatchset
