Question: In an OPEN CHANNEL command related to WLAN bearer, how does the Mobile Equipment (ME) select the WLAN, according to 3GPP specifications?
Option 1: Based on the I-WLAN Identifier provided in the command.
Option 2: Using the Manual PLMN Selection Mode Procedure as defined in TS 24.234.
Option 3: According to TS 24.302 using the automatic mode WLAN selection procedure, ignoring any provided I-WLAN Identifier.
Option 4: By utilizing the ME's default local address configuration.
Explanation: When the OPEN CHANNEL command is related to a WLAN bearer (as opposed to an I-WLAN bearer), the ME's selection process for the WLAN is governed by TS 24.302, which specifies the use of automatic mode for WLAN selection. Additionally, in this context, any provided I-WLAN Identifier is to be ignored, as indicated in the relevant 3GPP specifications. This ensures seamless integration with non-3GPP access networks, such as those defined for accessing the Evolved Packet Core (EPC) via WLAN.
