* lost due to many factors, including deactivateDataCall() being issued, the radio powered
* off, reception lost or even transient factors like congestion. This data call list is

*
* The Radio is expected to:
* - Create one data call context.
* - Create and configure a dedicated interface for the context.
* - The interface must be point to point.
* - The interface is configured with one or more addresses and is capable of sending and
* receiving packets. The prefix length of the addresses must be /32 for IPv4 and /128
* for IPv6.
* - Must not modify routing configuration related to this interface; routing management is
* exclusively within the purview of the Android OS.
* - Support simultaneous data call contexts up to DataRegStateResult.maxDataCalls specified
* in the response of getDataRegistrationState.

* addresses of the existing data connection. The format is IP address with optional "/"

* "192.0.1.11/16", or "2001:db8::1/64". Typically one IPv4 or one IPv6 or one of each. If
* the prefix length is absent, then the addresses are assumed to be point to point with
* IPv4 with prefix length 32 or IPv6 with prefix length 128. This parameter must be ignored
* unless reason is DataRequestReason.HANDOVER.
* @param dnses If the reason is DataRequestReason.HANDOVER, this indicates the list of DNS
* addresses of the existing data connection. The format is defined in RFC-4291 section

* Android uses this request to make its emergency call instead of using @1.0::IRadio.dial
* if the 'address' in the 'dialInfo' field is identified as an emergency number by Android.
*
* In multi-sim scenario, if the emergency number is from a specific subscription, this radio
* request is sent through the IRadio service that serves the subscription, no matter of the
* PUK/PIN state of the subscription and the service state of the radio.
*
* Some countries or carriers require some emergency numbers that must be handled with normal
* call routing if possible or emergency routing. 1) if the 'routing' field is specified as
* @1.4::EmergencyNumberRouting#NORMAL, the implementation must try the full radio service to
* use normal call routing to handle the call; if service cannot support normal routing, the
* implementation must use emergency routing to handle the call. 2) if 'routing' is specified
* as @1.4::EmergencyNumberRouting#EMERGENCY, the implementation must use emergency routing to
* handle the call. 3) if 'routing' is specified as @1.4::EmergencyNumberRouting#UNKNOWN,
* Android does not know how to handle the call.
*
* If the dialed emergency number does not have a specified emergency service category, the
* 'categories' field is set to @1.4::EmergencyServiceCategory#UNSPECIFIED; if the dialed
* emergency number does not have specified emergency Uniform Resource Names, the 'urns' field
* is set to an empty list. If the underlying technology used to request emergency services
* does not support the emergency service category or emergency uniform resource names, the
* field 'categories' or 'urns' may be ignored.
*
* In the scenarios that the 'address' in the 'dialInfo' field has other functions besides the
* emergency number function, if the 'hasKnownUserIntentEmergency' field is true, the user's
* intent for this dial request is emergency call, and the modem must treat this as an actual
* emergency dial; if the 'hasKnownUserIntentEmergency' field is false, Android does not know
* user's intent for this call.
*
* If 'isTesting' is true, this request is for testing purpose, and must not be sent to a real
* emergency service; otherwise it's for a real emergency call request.
