bsc: Increase T3101 in osmo-bsc.cfg
Test BSC_Tests.TC_ho_during_lcs_loc_req sporafically failed due to ttcn3 taking >2s to transmit the Handover Complete and T3101 (3s by default) firing before receiving it. Increase it to give some more room and avoid sporadic failures.
See how 2nd RSL1.send() in as_handover() is delayed for >2s: """ 09:50:39.134962 27946 MSC_ConnectionHandler.ttcn:1737 Sent on RSL1 to IPA-BTS1-TRX0-RSL-RSL(2945) @RSL_Types.RSL_Message : { msg_disc := { msg_group := RSL_MDISC_DCHAN (4), transparent := false }, msg_type := RSL_MT_HANDO_DET (39), ies := { { iei := RSL_IE_CHAN_NR (1), body := { chan_nr := { u := { sdcch4 := { tag := '001'B, sub_chan := 0 } }, tn := 0 } } } } } ... 09:50:39.135037 27946 Osmocom_Types.ttcn:126 Start timer T: 0.3 s 09:50:39.435079 27946 Osmocom_Types.ttcn:127 Timeout T: 0.3 s 09:50:39.718007 27937 M3UA_Emulation.ttcn:887 Timeout T_ASPUP_resend: 2 s 09:50:42.131009 27943 IPA_Emulation.ttcnpp:772 Message enqueued on IPA_PORT from system @IPL4asp_Types.ASP_RecvFrom : { connId := 1, remName := "127.0.0.1", remPort := 3003, locName := "127.0.0.1", locPort := 11000, proto := { tcp := { } }, userData := 0, msg := '00040008250120'O } id 17 09:50:42.188991 27946 MSC_ConnectionHandler.ttcn:1742 enc_PDU_ML3_MS_NW(): Encoding @MobileL3_Types.PDU_ML3_MS_NW: { discriminator := '0000'B, tiOrSkip := { skipIndicator := '0000'B }, msgs := { rrm := { handoverComplete := { messageType := '00101100'B, rRCause := { valuePart := '00'O }, mobileObsservedTimeDiff := omit, mobileTimeDifferenceHyperframe := omit } } } } """
