<ul></ul><p>The easy way of testing: merely send two distinct Assignment Commands from the MSC,<br />which cause a different chan_mode, like go from SPEEC_V1 to SPEECH_AMR.</p>
<p>Then it would also be good to model a congestion scenario, where no SDCCH are available and TCH/* need to help out.<br />osmo-bsc is fairly strictly giving out only SDCCH channels for Immediate Assignment,<br />it will initially only give an MS a TCH/F if all SDCCH are occupied.<br />So a congestion test would first need to occupy all SDCCH, e.g. with a series of "dummy" Chan Requests,<br />then send one more Chan Request, to get a TCH/* lchan in mode = SIGN;<br />and would then send an Assignment Command from the MSC, expecting a Chan Mode Modify, and not a new Chan Activ.</p> OsmoBSC - Bug #3357: osmo-bsc doesn't perform RSL MODE MODIFY on ASSIGNMENT if channel is compatible.https://projects.osmocom.org/issues/3357?journal_id=170452020-01-08T22:28:54Zlaforge
