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