1. A computer-implemented method for identifying locations of infrastructure assets, the method comprising:
identifying a location of a first infrastructure asset and a location of a second infrastructure asset;
identifying a region of interest extending at least partially between the locations of the first and second infrastructure assets;
obtaining an aerial image of the region of interest;
determining that the aerial image of the region of interest comprises a third infrastructure asset;
determining a location of the third infrastructure asset based at least in part on the aerial image; and
storing the location of the third infrastructure asset in an infrastructure asset datastore.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for an emergency call service by a terminal, the method comprising:
transmitting an attach request message together with a first packet data network (PDN) connectivity request message to a mobility management entity (MME), wherein the first PDN connectivity request message includes request type information indicating a request for a connectivity to a PDN for an emergency bearer service; and
receiving an attach accept message including an indicator from the MME, the indicator indicating whether the emergency bearer service is supported,
wherein the connectivity to the PDN for the emergency bearer service is established if the indicator indicates that the emergency bearer service is supported.
2. The method of claim 1, further comprising:
transmitting a second PDN connectivity request message including request type information to the MME, wherein the request type information indicates that the terminal requests to establish a new connectivity to the PDN; and
receiving an activate default evolved packet system (EPS) bearer context request message from the MME in response to the second PDN connectivity request message.
3. The method of claim 2, wherein the transmitting the second PDN connectivity request message is performed without waiting for deactivation of the established connectivity to the PDN for the emergency bearer service.
4. The method of claim 1, wherein if the indicator indicates that the emergency bearer service is not supported, the connectivity to the PDN for the emergency bearer service is not established.
5. A method for an emergency call service by a Mobility Management Entity (MME), the method comprising:
receiving an attach request message together with a first packet data network (PDN) connectivity request message from a terminal, wherein the first PDN connectivity request message includes request type information indicating a request for a connectivity to a PDN for an emergency bearer service; and
transmitting an attach accept message including an indicator to the terminal, the indicator indicating whether the emergency bearer service is supported,
wherein the connectivity to the PDN for the emergency bearer service is established if the indicator indicates that the emergency bearer service is supported.
6. The method of claim 5, further comprising:
receiving a second PDN connectivity request message including request type information from the terminal, wherein the request type information indicates that the terminal requests to establish a new connectivity to the PDN; and
transmitting an activate default evolved packet system (EPS) bearer context request message to the terminal in response to the second PDN connectivity request message.
7. The method of claim 6, wherein the second PDN connectivity request message is transmitted without waiting for deactivation of the established connectivity to the PDN for the emergency bearer service.
8. The method of claim 5, wherein if the indicator indicates that the emergency bearer service is not supported, the connectivity to the PDN for the emergency bearer service is not established.
9. A terminal for providing an emergency call service, the terminal comprising:
a transmitter configured to transmit an attach request message together with a first packet data network (PDN) connectivity request message to a mobility management entity (MME), wherein the first PDN connectivity request message includes request type information indicating a request for a connectivity to a PDN for an emergency bearer service; and
a receiver configured to receive an attach accept message including an indicator from the MME, the indicator indicating whether the emergency bearer service is supported,
wherein the connectivity to the PDN for the emergency bearer service is established if the indicator indicates that the emergency bearer service is supported.
10. The terminal of claim 9,
wherein the transmitter is further configured to transmit a second PDN connectivity request message including request type information to the MME, wherein the request type information indicates that the terminal requests to establish a new connectivity to the PDN, and
the receiver is further configured to receive an activate default evolved packet system (EPS) bearer context request message from the MME in response to the second PDN connectivity request message.
11. The terminal of claim 10, wherein the transmitter is further configured to transmit the second PDN connectivity request message without waiting for deactivation of the established connectivity to the PDN for the emergency bearer service.
12. The terminal of claim 9, wherein, if the indicator indicates that the emergency bearer service is not supported, the connectivity to the PDN for the emergency bearer service is not established.
13. A Mobility Management Entity (MME) for providing an emergency call service, the MME comprising:
a receiver configured to receive an attach request message together with a first packet data network (PDN) connectivity request message from a terminal, wherein the first PDN connectivity request message includes request type information indicating a request for a connectivity to a PDN for an emergency bearer service; and
a transmitter configured to transmit an attach accept message including an indicator to the terminal, the indicator indicating whether the emergency bearer service is supported,
wherein the connectivity to the PDN for the emergency bearer service is established if the indicator indicates that the emergency bearer service is supported.
14. The MME of claim 13, wherein the receiver is further configured to receive a second PDN connectivity request message including request type information from the terminal, wherein the request type information indicates that the terminal requests to establish a new connectivity to the PDN, and
wherein the transmitter is further configured to transmit an activate default evolved packet system (EPS) bearer context request message to the terminal in response to the second PDN connectivity request message.
15. The MME of claim 14, wherein the second PDN connectivity request message is transmitted without waiting for deactivation of the established connectivity to the PDN for the emergency bearer service.
16. The MME of claim 13, wherein, if the indicator indicates that the emergency bearer service is not supported, the connectivity to the PDN for the emergency bearer service is not established.
