_WWAN_USSD_SESSION_STATE enumeration

Description

The WWAN_USSD_SESSION_STATE enumeration lists the different types of USSD session states.

Constants

WwanUssdSessionStateNew

The USSD string is the first message of a USSD session.

WwanUssdSessionStateExisting

The USSD string is not the first message of a USSD session.

Remarks

Miniport drivers use the WWAN_USSD_SESSION_STATE enumeration to indicate whether a USSD string is the first message of a USSD session. Miniport drivers must use WwanUssdSessionStateNew for the first message of a network-initiated USSD session. Miniport drivers should use WwanUssdSessionStateExisting in all other cases.
