Description

Set command enables or disables the WLAN offload assistance data reporting. If reporting is enabled by <n>=1, the MT returns the following unsolicited result code from MT to TE whenever the WLAN offload assistance data changes at the MT:

+CWLANOLADI: [,<threshRSCPLow>,<threshRSCPHigh>[,<threshEcnoLow>,<threshEcnoHigh>[,<threshRSRPLow>,<threshRSRPHigh>[,<threshRSRQLow>,<threshRSRQHigh>[,<threshChUtilLow>,<threshChUtilHigh>[,<threshBackhRateDLLow>,<threshBackhRateDLHigh>[,<threshBackhRateULLow>,<threshBackhRateULHigh>[,<threshBeaconRSSILow>,<threshBeaconRSSIHigh>[,<opi>[,<tSteering>[,<WLANIdentifierListLength>[,<ssid_1>,<bssid_1>,<hessid_1>][,<ssid_2>,<bssid_2>,<hessid_2>][,…]]]]]]]]]]]]

Refer IE WLAN-OffloadConfig in 3GPP TS 36.331 [86] clause 6.3.6.

If a setting is not supported by the MT, +CME ERROR: <err> is returned. Refer clause 9.2 for possible <err> values.

Read command returns the current status of <n> and the WLAN offload assistance data currently available at the MT.

Test command returns the values supported by MT as compound values.
