Support CSFB "Fast Return"
Added by laforge about 5 years ago.
Updated about 5 years ago.
Description
In order to help the MS/UE to return fast[er] to LTE, OsmoMSC should implement the following bit:
- The MSC sends the "CSFB indication" IE as part of BSSMAP CLEAR COMMAND on the A interface (see TS 48.008 3.2.2.121)
This will be used by the BSC to then trigger the inclusion of related IEs in the RR RELEASE
- Assignee set to dexter
- Priority changed from Normal to High
Assigning this for dexter to implement as separate patch on top of his SGs patch/branch. OsmoBSC already has the implementation [pending master merge], see #3777.
- Status changed from New to In Progress
- % Done changed from 0 to 10
- % Done changed from 10 to 70
Both libosmocore and omso-msc change have been merged. What's missing is testing it as part of our TTCN-3 testsuite.
- Status changed from In Progress to Stalled
- Assignee changed from dexter to laforge
I've tried to create a TTCN-3 test for this, but it appears that TITAN doesn't correctly parse/decode the CSFB Indicator of the BSSMAP Clear Command. I've posted a related message to the TITAN forum: https://www.eclipse.org/forums/index.php/m/1802832
- Related to Bug #3805: OsmoMSC sends invalid BSSMAP length field on CSFB CLEAR COMMAND added
- Status changed from Stalled to In Progress
- Status changed from In Progress to Resolved
- % Done changed from 70 to 100
