List of Timer numbers¶
- Table of contents
- List of Timer numbers
Below is a list of timer numbers used in Osmocom programs.
Many are specified by 3GPP specifications, indicated by a T (like T3103).
There are also various Osmocom specific timers, indicated by an X (like X23).
Timers specified by 3GPP¶
| configurable | Timer | Program | Purpose |
|---|---|---|---|
| yes | T7 | OsmoBSC | inter-BSC/MSC Handover outgoing, BSSMAP HO Required to HO Command timeout |
| yes | T8 | OsmoBSC | inter-BSC/MSC Handover outgoing, BSSMAP HO Command to final Clear timeout |
| yes | T10 | OsmoBSC | RR Assignment |
| yes | T101 | OsmoBSC | inter-BSC/MSC Handover incoming, BSSMAP HO Request to HO Accept |
| yes | T3101 | OsmoBSC | RR Immediate Assignment |
| yes | T3103 | OsmoBSC | Handover |
| yes | T3105 | OsmoBSC | Physical Information |
| yes | T3107 | OsmoBSC | (unused) |
| yes | T3109 | OsmoBSC | RSL SACCH deactivation |
| yes | T3111 | OsmoBSC | Wait time before RSL RF Channel Release |
| yes | T3113 | OsmoBSC | Paging |
| yes | T3115 | OsmoBSC | (unused) |
| yes | T3117 | OsmoBSC | (unused) |
| yes | T3119 | OsmoBSC | (unused) |
| yes | T3122 | OsmoBSC | Wait time after RR Immediate Assignment Reject |
| yes | T3141 | OsmoBSC | (unused) |
| yes | T3212 | OsmoBSC | Periodic Location Update timer, sent to MS (1 = 6 minutes) |
Timers specific to Osmocom¶
| configurable | Timer | Program | Purpose |
|---|---|---|---|
| yes | X1 | OsmoBTS | Time after which osmo-bts exits if regular ramp down during shut down process does not finish (s) |
| yes | X1 | OsmoBSC | MGCP response timeout |
| yes | X2 | OsmoBTS | Time after which osmo-bts exits if requesting transceivers to stop during shut down process does not finish (s) |
| yes | X2 | OsmoBSC | RTP stream establishing timeout |
| yes | X23002 | OsmoBSC | Wait time for RSL Channel Activate ACK after sending RSL Channel Activate |
| yes | X23005 | OsmoBSC | Wait time for RSL IPA CRCX ACK after sending RSL IPA CRCX |
| yes | X23006 | OsmoBSC | Wait time for RSL IPA MDCX ACK after sending RSL IPA MDCX |
Legacy timer numbers: specific to Osmocom, but still defined as T timers¶
| configurable | Legacy T timer | corresponding X timer | Software | Purpose |
|---|---|---|---|---|
| yes | T2427001 | - | libosmo-mgcp-client OsmoBSC OsmoMSC | timeout for MGCP response from MGW |
| yes | T992427 | - | OsmoBSC | MGCP timeout (2427 is the default MGCP port number) |
| yes | T993111 | - | OsmoBSC | Wait time after lchan was released in error (should be T3111 + 2s) |
| yes | T993210 | - | OsmoBSC | After L3 Complete, wait for MSC to confirm |
| yes | T999 | - | OsmoBSC | After Clear Request, wait for MSC to Clear Command (sanity) |
