Out-of-band service discovery indication
Methods, systems, and devices for wireless communication are described. An access point (AP) may include a service discovery indicator in a broadcast message. A user equipment (UE) may tune to the radio frequency spectrum band of the AP and receive the broadcast message. The UE may identify a web resource based on the service discovery indicator and access the web resource to determine the capability configuration of the AP. The UE may access the web resource using an existing internet connection of its currently serving AP.
1. A method of wireless communication comprising:
tuning away, by a single tuner of a wireless device, from a second radio frequency spectrum band to a first radio frequency spectrum band, wherein the tuning away is to detect a presence of a first access point (AP);
receiving, via the first AP in the first radio frequency spectrum band while tuned away from the second radio frequency spectrum band, a broadcast message comprising a service discovery indicator, wherein the service discovery indicator provides an indication that the first AP supports out-of-band service capability discovery;
identifying, based at least in part on the service discovery indicator, a web resource associated with a capability configuration of the first AP; and
accessing, via a second AP in the second radio frequency spectrum band, the web resource to determine the capability configuration of the first AP in the first radio frequency spectrum band.
2. The method of claim 1 , further comprising:
determining, based on the capability configuration of the first AP, to switch from the second AP to the first AP for wireless communications in the first radio frequency spectrum band.
3. The method of claim 1 , wherein receiving the broadcast message comprises:
decoding an information block broadcast by the first AP in the first radio frequency spectrum band.
4. The method of claim 3 , wherein the information block comprises at least one of a master information block (MIB) or a system information block (SIB).
5. The method of claim 1 , wherein identifying the web resource comprises:
computing an address of the web resource based at least in part on the service discovery indicator.
6. The method of claim 5 , wherein the address comprises at least one of an internet protocol (IP) address, a fully qualified domain name (FQDN), or a uniform resource identifier (URI) of the web resource.
7. The method of claim 1 , wherein the first radio frequency spectrum band is an unlicensed radio frequency spectrum band associated with a MulteFire wireless network.
8. The method of claim 1 , wherein the first radio frequency spectrum band is associated with a neutral host small cell wireless network.
9. The method of claim 1 , wherein the service discovery indicator comprises an address of the web resource.
10. A method of wireless communication comprising:
tuning away, by a single tuner of a wireless device, from a second radio frequency spectrum band to a first radio frequency spectrum band, wherein the tuning away is to detect a presence of a first access point (AP);
receiving, via the first access point (AP) in the first radio frequency spectrum band while tuned away from the second radio frequency spectrum band, a broadcast message;
identifying, based at least in part on the broadcast message, a web resource associated with a capability configuration of the first AP; and
accessing, via a second AP in the second radio frequency spectrum band, the web resource to determine the capability configuration of the first AP in the first radio frequency spectrum band.
11. The method of claim 10 , further comprising:
determining, based on the capability configuration of the first AP, to switch from the second AP to the first AP for wireless communications in the first radio frequency spectrum band.
12. The method of claim 10 , wherein receiving the broadcast message comprises:
decoding an information block broadcast by the first AP in the first radio frequency spectrum band.
13. The method of claim 12 , wherein the information block comprises at least one of a master information block (MIB) or a system information block (SIB).
14. The method of claim 10 , wherein identifying the web resource comprises:
computing an address of the web resource based at least in part on an identifier of the first AP included in the broadcast message.
15. An apparatus for wireless communication comprising:
a processor;
memory in electronic communication with the processor; and
instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
tune away, by a single tuner of the apparatus, from a second radio frequency spectrum band to a first radio frequency spectrum band, wherein the tuning away is to detect a presence of a first access point (AP);
receive, via the first AP in the first radio frequency spectrum band while tuned away from the second radio frequency spectrum band, a broadcast message comprising a service discovery indicator, wherein the service discovery indicator provides an indication that the first AP supports out-of-band service capability discovery;
identify, based at least in part on the service discovery indicator, a web resource associated with a capability configuration of the first AP; and
access, via a second AP in the second radio frequency spectrum band, the web resource to determine the capability configuration of the first AP in the first radio frequency spectrum band.
16. The apparatus of claim 15 , wherein the instructions are operable to cause the processor to:
determine, based on the capability configuration of the first AP, to switch from the second AP to the first AP for wireless communications in the first radio frequency spectrum band.
17. The apparatus of claim 15 , wherein the instructions to cause the apparatus to receive the broadcast message comprise instructions to cause the apparatus to:
decode an information block broadcast by the first AP in the first radio frequency spectrum band.
18. The apparatus of claim 17 , wherein the information block comprises at least one of a master information block (MIB) or a system information block (SIB).
19. The apparatus of claim 15 , wherein the instructions to cause the apparatus to identify the web resource comprise instructions to cause the apparatus to:
compute an address of the web resource based at least in part on the service discovery indicator.
20. The apparatus of claim 19 , wherein the address comprises at least one of an internet protocol (IP) address, a fully qualified domain name (FQDN), or a uniform resource identifier (URI) of the web resource.
21. The apparatus of claim 15 , wherein the first radio frequency spectrum band is an unlicensed radio frequency spectrum band associated with a MulteFire wireless network.
22. The apparatus of claim 15 , wherein the first radio frequency spectrum band is associated with a neutral host small cell wireless network.
