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:
transmitting, by a user equipment (UE) to a network node, a registration message comprising:
a first indicator configured to indicate language information and
a second indicator configured to indicate a status of previously received emergency information, the second indicator including a result of a hashing function of the previously received emergency information; and
receiving, by the user equipment from the network node, a registration accept message.
2. The method of claim 1 , wherein the registration message further comprises a third indicator configured to indicate emergency call information display capability.
3. The method of claim 2 , wherein the emergency call information display capability comprises one or more of:
the UE is configured to display an emergency call service type;
the UE comprises a display;
a mobile equipment (ME) domain of the UE is configured to communicate descriptions of emergency identifiers;
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.
4. The method of claim 1 , wherein the language information comprises one or more of:
languages or encodings supported by the UE;
languages or encodings preferred by the UE; or
languages or encodings supported by an end user of the UE.
5. The method of claim 1 , 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 method of claim 1 , further comprising:
receiving, from the network node, a list of descriptions of emergency identifiers when the indicator indicates of no previously stored descriptions of emergency identifiers; and
storing the list of descriptions of emergency identifiers.
7. A user equipment (UE) comprising:
a memory; and
a processor coupled to the memory, the processor configured to:
transmit, to a network node, a registration message comprising a first indicator configured to indicate language information and a second indicator configured to indicate a status of previously received emergency information, the second indicator including a result of a hashing function of the previously received emergency information; and
receive, from the network node, a registration accept message.
8. The UE of claim 7 , wherein the registration message further comprises a third indicator configured to indicate emergency call information display capability.
9. The UE of claim 8 , wherein emergency call information display capability comprises one or more of:
the UE is configured to display an emergency call service type;
the UE comprises a display;
a mobile equipment (ME) domain of the UE is configured to communicate descriptions of emergency identifiers;
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.
10. The UE of claim 7 , wherein the language information comprises one or more of:
languages or encodings supported by the UE;
languages or encodings preferred by the UE; or
languages or encodings supported by an end user of the UE.
11. The UE of claim 7 , 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.
12. The UE of claim 7 , wherein the processor is further configured to:
receive, from the network node, a list of descriptions of emergency identifiers when a third indicator indicates of no previously stored descriptions of emergency identifiers; and
store the list of descriptions of emergency identifiers.
13. A computer program product comprising instructions embodied on a non-transitory computer readable storage medium, wherein the instructions, when executed by a processor, cause a user equipment (UE) to:
transmit, to a network node, a registration message comprising a first indicator configured to indicate language information and a second indicator configured to indicate a status of previously received emergency information, the second indicator including a result of a hashing function of the previously received emergency information; and
receive, from the network node, a registration accept message.
14. The computer program product of claim 13 , wherein the registration message further comprises a third indicator configured to indicate emergency call information display capability.
15. The computer program product of claim 14 , wherein emergency call information display capability comprises one or more of:
the UE is configured to display an emergency call service type;
the UE comprises a display;
a mobile equipment (ME) domain of the UE is configured to communicate descriptions of emergency identifiers;
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.
16. The computer program product of claim 13 , wherein the language information comprises one or more of:
languages or encodings supported by the UE;
languages or encodings preferred by the UE; or
languages or encodings supported by an end user of the UE.
17. The computer program product of claim 13 , 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.
18. The computer program product of claim 13 , wherein the processor is further configured to:
receive, from the network node, a list of descriptions of emergency identifiers when a third indicator indicates of no previously stored descriptions of emergency identifiers; and
store the list of descriptions of emergency identifiers.
