nRF9160 getting stuck after cell change (ESM cause #26)

[Oliver Wierichs]

NOTE: This is related to the following issue: https://devzone.nordicsemi.com/f/nordic-q-a/63255/nrf9160-getting-stuck-after-cell-change

--------------------------------------------------------------------------------

Hi,

we are running into issues where the nRF9160 (in NB-IoT mode) does not seem to handle cell changes reliably. I am using modem firmware mfw_nrf9160_1.2.0 .

We made a simplified test firmware to debug the issue. The test firmware enables several unsolicited notifications from the modem and prints them to the log. It then sends a UDP packet every 30s to a server which logs them. It also calls AT%XMONITOR and AT%NBRGRSRP in hope to get additional information. The AT commands at startup are as follows:

AT%XSYSTEMMODE=0,1,0,2 // Set modem to NB-IoT mode
AT+CGMR // Query modem firmware
AT%XCBAND=? // Query supported bands
AT+CMEE=1 // Subscribe to mobile termination error
AT+CEREG=5 // Subscribe to network registration status
AT+CGEREP=1 // Subscribe to packet domain events
AT+CNEC=24 // Subscribe to network error codes
AT%CESQ=1 // Subscribe to signal quality
AT+CEINFO=1 // Subscribe to Coverage Enhancement notifications
AT%XBANDLOCK=2,"10000000000000000000" // Run-time lock to band 20

AT+CFUN=1 // Enable modem

// *** after connect ***

AT%XCBAND // Query current band
AT+CIMI // Query IMSI
AT+CGPADDR // Query IP address

After a while, sendto starts to fail with errno=ENETUNREACH. The logs show that this is because there is no longer a packet domain connection. The problem can be provoked by driving the system around in a car (more cell changes), but also happens after a few days if the system is stationary. It does seem to fix itself eventually, but may take many hours to do so. However, if I reset the system, it instantly connects again.

The log file looks as follows:

In this case, we observe the following Error messages:

• +CNEC_ESM: 26,0 (Session Management Error: Insufficient resources)

• +CNEC_EMM: 19 (Mobility Management Error: ESM failure)

• +CGEV: RESTR 2,2

  • Requested procedure restricted:

  • 2 – Throttling. Procedure restricted by 3GPP or operator-specific throttling.

  • 2 – Temporary restriction. Enabling requires e.g. back-off timer expiry.

According to the following site, this is related to the back-off timer T3396: https://itectec.com/spec/6-5-ue-requested-esm-procedures/ 

(see chapter 6.5.1.4.2 Handling of network rejection due to ESM cause #26)

What would be the appropriate action to prevent this error ?

Does Nordic use this timer, and can it be modified ?
