Support of emergency number descriptions
A method comprising transmitting, by a user equipment (UE) to a network node, a registration message comprising at least one of a first indicator configured to indicate emergency call information display capability, a second indicator configured to indicate language information, or a third indicator configured to indicate a status of previously received emergency information, and receiving, by the user equipment from the network node, a registration accept message.
1. A method comprising:
receiving, by a network node from a user equipment (UE), a registration request comprising a first indicator configured to indicate emergency call information display capability, wherein the first indicator indicates whether a mobile equipment (ME) domain of the UE is configured to send descriptions of emergency identifiers to a display of the UE, and wherein the registration request further comprises a mobile country code (MCC);
determining, by the network node, whether the descriptions of emergency identifiers need to be included in a registration accept message;
in response to determining that the descriptions of emergency identifiers need to be included in a registration accept message, selecting, by the network node, a language to use for transmitting the description of emergency identifiers based on the MCC; and
transmitting, from the network node to the UE, the registration accept message comprising the descriptions of emergency identifiers, wherein the descriptions of emergency identifiers are in the determined language,
wherein the registration further comprises a third indicator configured to indicate a status of previously received emergency information, and wherein the status of previously received emergency information comprises one or more of:
the UE has previously stored previously received descriptions of emergency identifiers,
an indication of the previously received descriptions of emergency identifiers,
an indication of previously received emergency identifiers, or
an indication of no previously stored descriptions of emergency identifiers.
2. The method of claim 1 , wherein the emergency call information display capability further comprises one or more of:
the UE is configured to display an emergency call service type;
the UE comprises a display;
the UE is configured to store the descriptions of emergency identifiers; or
a quantity of the descriptions of emergency identifiers the UE is configured to store.
3. The method of claim 1 , wherein the registration further comprises a second indicator configured to indicate language information, and wherein the language information comprises one or more of:
languages or encoding supported by the UE;
languages or encodings preferred by the UE; or
languages or encodings supported by an end user of the UE.
4. The method of claim 1 , further comprising:
determining, by the network node, a list of descriptions of emergency identifiers based on the registration request; and
transmitting, by the network node to the UE, the list of descriptions of emergency identifiers when the third indicator comprises the indication of no previously stored descriptions of emergency identifiers.
5. A network node comprising:
a memory; and
a processor, wherein the processor is configured to:
receive, from a user equipment (UE), a registration request comprising a first indicator configured to indicate emergency call information display capability, wherein the first indicator indicates whether a mobile equipment (ME) domain of the UE is configured to send descriptions of emergency identifiers to a display of the UE, and wherein the registration request further comprises a mobile country code (MCC);
determine whether the descriptions of emergency identifiers need to be included in a registration accept message;
in response to determining that the descriptions of emergency identifiers need to be included in a registration accept message, selecting a language to use for transmitting the description of emergency identifiers based on the MCC; and
transmit, to the UE, the registration accept message comprising the descriptions of emergency identifiers, wherein the descriptions of emergency identifiers are in the determined language,
wherein the registration further comprises a third indicator configured to indicate a status of previously received emergency information, and wherein the status of previously received emergency information comprises one or more of:
the UE has previously stored previously received descriptions of emergency identifiers,
an indication of the previously received descriptions of emergency identifiers,
an indication of previously received emergency identifiers, or
an indication of no previously stored descriptions of emergency identifiers.
6. The network node of claim 5 , wherein the emergency call information display capability further comprises one or more of:
the UE is configured to display an emergency call service type;
the UE comprises a display;
the UE is configured to store the descriptions of emergency identifiers; or
a quantity of the descriptions of emergency identifiers the UE is configured to store.
7. The network node of claim 5 , wherein the registration further comprises a second indicator configured to indicate language information, and wherein the language information comprises one or more of:
languages or encoding supported by the UE;
languages or encodings preferred by the UE; or
languages or encodings supported by an end user of the UE.
8. The network node of claim 5 , wherein the processor is further configured to:
determine a list of descriptions of emergency identifiers based on the registration request; and
transmit, to the UE, the list of descriptions of emergency identifiers when the third indicator comprises the indication of no previously stored descriptions of emergency identifiers.
9. A non-transitory computer readable medium containing instructions that when executed by a processor cause the processor to:
receive, from a user equipment (UE), a registration request comprising a first indicator configured to indicate emergency call information display capability, wherein the first indicator indicates whether a mobile equipment (ME) domain of the UE is configured to send descriptions of emergency identifiers to a display of the UE, and wherein the registration request further comprises a mobile country code (MCC);
determine whether the descriptions of emergency identifiers need to be included in a registration accept message;
in response to determining that the descriptions of emergency identifiers need to be included in a registration accept message, selecting a language to use for transmitting the description of emergency identifiers based on the MCC; and
transmit, to the UE, the registration accept message comprising the descriptions of emergency identifiers, wherein the descriptions of emergency identifiers are in the determined language,
wherein the registration further comprises a third indicator configured to indicate a status of previously received emergency information, and wherein the status of previously received emergency information comprises one or more of:
the UE has previously stored previously received descriptions of emergency identifiers;
an indication of the previously received descriptions of emergency identifiers;
an indication of previously received emergency identifiers; or
an indication of no previously stored descriptions of emergency identifiers.
10. The non-transitory computer readable medium of claim 9 , wherein the emergency call information display capability further comprises one or more of:
the UE is configured to display an emergency call service type;
the UE comprises a display;
the UE is configured to store the descriptions of emergency identifiers; or
a quantity of the descriptions of emergency identifiers the UE is configured to store.
11. The non-transitory computer readable medium of claim 9 , wherein the registration further comprises a second indicator configured to indicate language information, and wherein the language information comprises one or more of:
languages or encoding supported by the UE;
languages or encodings preferred by the UE; or
languages or encodings supported by an end user of the UE.
12. The non-transitory computer readable medium of claim 9 , wherein the instructions when executed by the processor further configure the processor to:
determine a list of descriptions of emergency identifiers based on the registration request; and
transmit, to the UE, the list of descriptions of emergency identifiers when the third indicator comprises the indication of no previously stored descriptions of emergency identifiers.
