pespin gerrit-no-reply at lists.osmocom.orgpespin has uploaded a new patch set (#2) to the change originally created by laforge. ( https://gerrit.osmocom.org/c/osmo-sgsn/+/18877 ) Change subject: Treat RAU as implicit RESUME if GMM is suspended ...................................................................... Treat RAU as implicit RESUME if GMM is suspended We so far only resumed from suspend upon receiving an explicit BSSGP RESUME message from the BSS. The latter is only possible in BSC-colocated PCU, where the BSC can trigger the message when releasing the dedicated channel. In BTS-colocated PCUs, this is not possible, and we have to rely on the MS resuming by RAU. See 3GPP TS 23.060 section 16.2.1.1.1 clause 6: The MS shall resume GPRS services by sending a Routeing Area Update Request message to the SGSN: * if the BSS did not successfully request the SGSN to resume GPRS services, * if the RR Channel Release message was not received before the MS left dedicated mode, * if the MS locally determines that the conditions for the GPRS suspension have disappeared Without this patch, the GMM state would forever be stuck in SUSPEND, which in turn causes the SGSN to page the MS all the time.
