( https://gerrit.osmocom.org/c/osmo-msc/+/15527 ) Change subject: paging: reduce paging response timer to 3 sec ...................................................................... Patch Set 5: This is possibly dangerous. Paging on GSM can take a rather long time, and it depends on factors such as CCCH/PCH capacity, configuration parameters such as number of paging groups, DRX cycle, ... See e.g. http://gsm-optimization.blogspot.com/2012/04/paging-group.html or http://etutorials.org/Mobile+devices/gprs+mobile+internet/Chapter+5+Radio+Interface+RLC+MAC+Layer/Listening+to+MS+Paging+Blocks/ If you have configured 9 paging groups, then the paging of one group only occurs once every 9 51-multiframes, which is 9*240ms, i.e. 2.1 seconds. And as you mapy page any number of MS at the same time in that paging group, there's queueing and quite a bit of delay. so 10s is actually not even the upper bound, IMHO. -- To view, visit https://gerrit.osmocom.org/c/osmo-msc/+/15527 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: osmo-msc Gerrit-Branch: master Gerrit-Change-Id: Ie695aa67458753794d70ed5154df51bfe6696da3 Gerrit-Change-Number: 15527 Gerrit-PatchSet: 5 Gerrit-Owner: lynxis lazus <lynxis at fe80.eu> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: pespin <pespin at sysmocom.de> Gerrit-CC: laforge <laforge at osmocom.org> Gerrit-Comment-Date: Wed, 09 Oct 2019 16:56:37 +0000 Gerrit-HasComments: No Gerrit-Has-Labels: No Gerrit-MessageType: comment -------------- next part -------------- An HTML attachment was scrubbed...
