OID_WW_MBX_TRAFFIC_AREA
The OID_WW_MBX_TRAFFIC_AREA OID requests the miniport driver to return information about the most recently received traffic-area frame as one of the following:
| Value | Meaning |
|---|---|
in_traffic_area |
Mobile unit has entered a subscribed traffic area. |
in _auth_traffic_area |
Mobile unit is outside traffic area but is authorized. |
unauth_traffic_area |
Mobile unit is outside traffic area and is unauthorized. |
unknown_traffic_area |
The driver has no information about the current traffic area. |
The radio modem sends a traffic area frame to the computer whenever the radio changes traffic area. The miniport driver should save the current value indicated in such a frame to support this OID.
If any bound protocol has enabled indications with OID_WW_GEN_INDICATION_REQUEST, the miniport driver must call NdisMIndicateStatusto notify such protocol(s) when the traffic area changes. It can ignore the TriggerValue member that was specified in the OID_WW_GEN_INDICATION_REQUEST.
Sets are irrelevant for this OID.
Note This OID is not available for use beginning with Windows Vista.
