Uplink data indication
A wireless device receives, from a mobility management entity (MME), an attach accept message for establishing a packet data network (PDN) connection of the wireless device. The message indicates that transmission of uplink data via the PDN connection is not allowed until the wireless device receives an indication that transmission of uplink data via the PDN connection is allowed. Based on receiving the indication that transmission of uplink data via the PDN connection is allowed, sending, by the wireless device to a PDN gateway (PGW) one or more uplink packets associated with the PDN connection.

2. The method of claim 1 , wherein the one or more uplink packets are associated with an aerial service.
3. The method of claim 2 , further comprising sending, by a wireless device to the MME, an attach request message comprising a protocol configuration options indicating the aerial service.
4. The method of claim 2 , wherein the indication of the aerial service comprises a civil aviation authority uncrewed aerial vehicle identifier of the wireless device.
5. The method of claim 2 , wherein the indication that transmission of uplink data via the PDN connection is allowed comprises an authentication and/or authorization result associated with the aerial service.
6. The method of claim 1 , wherein the attach accept message comprises an evolved packet system bearer context message indicating that transmission of uplink data via the PDN connection is not allowed until the wireless device receives an indication that transmission of uplink data via the PDN connection is allowed.
7. The method of claim 1 , wherein the attach accept message comprises an evolved packet system bearer context message comprising a protocol configuration options indicating that transmission of uplink data via the PDN connection is not allowed until the wireless device receives an indication that transmission of uplink data via the PDN connection is allowed.
8. The method of claim 1 , further comprising receiving, by the wireless device from the MME, a modify evolved packet system bearer context message comprising the indication that transmission of uplink data via the PDN connection is allowed.
9. The method of claim 1 , further comprising receiving, by the wireless device from the MME, a modify evolved packet system bearer context message comprising a protocol configuration options comprising the indication that transmission of uplink data via the PDN connection is allowed.
10. The method of claim 1 , wherein based on the indication that transmission of uplink data via the PDN connection is not allowed, the wireless device does not send the one or more uplink packets associated with the PDN connection until the wireless device receives the indication that transmission of the uplink data via the PDN connection is allowed.
11. A wireless device comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
receive, from a mobility management entity (MME), an attach accept message:
for establishing a packet data network (PDN) connection of the wireless device; and
indicating that transmission of uplink data via the PDN connection is not allowed until the wireless device receives an indication that transmission of uplink data via the PDN connection is allowed; and
based on receiving the indication that transmission of uplink data via the PDN connection is allowed, send, to a PDN gateway (PGW) one or more uplink packets associated with the PDN connection.
12. The wireless device of claim 11 , wherein the one or more uplink packets are associated with an aerial service.
13. The wireless device of claim 12 , further comprising sending, by a wireless device to the MME, an attach request message comprising a protocol configuration options indicating the aerial service.
14. The wireless device of claim 12 , wherein the indication of the aerial service comprises a civil aviation authority uncrewed aerial vehicle identifier of the wireless device.
15. The wireless device of claim 12 , wherein the indication that transmission of uplink data via the PDN connection is allowed comprises an authentication and/or authorization result associated with the aerial service.
16. The wireless device of claim 11 , wherein the attach accept message comprises an evolved packet system bearer context message indicating that transmission of uplink data via the PDN connection is not allowed until the wireless device receives an indication that transmission of uplink data via the PDN connection is allowed.
17. The wireless device of claim 11 , wherein the attach accept message comprises an evolved packet system bearer context message comprising a protocol configuration options indicating that transmission of uplink data via the PDN connection is not allowed until the wireless device receives an indication that transmission of uplink data via the PDN connection is allowed.
18. The wireless device of claim 11 , further comprising receiving, by the wireless device from the MME, a modify evolved packet system bearer context message comprising a protocol configuration options comprising the indication that transmission of uplink data via the PDN connection is allowed.
19. The wireless device of claim 11 , wherein based on the indication that transmission of uplink data via the PDN connection is not allowed, the wireless device does not send the one or more uplink packets associated with the PDN connection until the wireless device receives the indication that transmission of the uplink data via the PDN connection is allowed.
20. A system comprising:
a packet data network, PDN, gateway, PGW, comprising: one or more processors and memory storing instructions that, when executed by the one or more processors, cause the PGW to:
send, to a mobility management entity, MME, an indication that transmission of uplink data via a PDN connection of a wireless device is not allowed until the wireless device receives an indication that transmission of uplink data via the PDN connection is allowed;
receive, from the wireless device, one or more uplink packets associated with the PDN connection; and
the MME, wherein the MME comprises: one or more processors and memory storing instructions that, when executed by the one or more processors, cause the MME to:
receive, from the PGW, the indication that transmission of uplink data via the PDN connection is not allowed until the wireless device receives the indication that transmission of uplink data via the PDN connection is allowed; and
send, to the wireless device, a message:
for establishing the PDN connection of the wireless device; and
indicating that transmission of uplink data via the PDN connection is not allowed until the wireless device receives the indication that transmission of uplink data via the PDN connection is allowed; and
