Network data analytics function selection
A method, a computer-readable medium, and an apparatus are provided for a network entity. The network entity receives an analytics request from a consumer, the analytics request indicating at least one analytic and determines one or more network data analytics functions (NWDAFs) for the analytics request based on the at least one analytic indicated in the analytics request. A consumer sends an analytics request to a network entity including one or more analytics identifiers. The consumer receives, from the network entity, a response to the analytics request including an analytics output from one or more NWDAFs based on the analytics identifier(s) included in the analytics request. An NWDAF sends an analytics identifier registration to a network entity indicating one or more analytics supported by the NWDAF. Then, the NWDAF receives an analytics request(s) from consumer(s) via the network entity based on the NWDAF supporting an analytic in the analytics request.
1. A method of wireless communication at a network entity comprised in a wireless network, comprising:
receiving, at the network entity, an analytics request from a consumer of the wireless network, the analytics request including a first analytics identifier and a second analytics identifier;
determining a first network data analytics function (NWDAF) based on the first analytics identifier indicated in the analytics request and a second NWDAF based on the second analytics identifier indicated in the analytics request;
forwarding, from the network entity, a request to multiple NWDAFs, including forwarding a first request to the first NWDAF based on the first analytics identifier indicated in the analytics request and forwarding a second request to the second NWDAF based on the second analytics identifier indicated in the analytics request;
receiving multiple analytics responses including an analytics response from each of the multiple NWDAFs, including receiving a first analytics response from the first NWDAF and receiving a second analytics response from the second NWDAF;
combining the multiple analytics responses into a combined analytics response, wherein the network entity provides the combined analytics response to the consumer based on a combination of the first analytics response that the network entity received from the first NWDAF and the second analytics response that the network entity received from the second NWDAF; and
providing, to the consumer, the combined analytics response based on the combination of the first analytics response received from the first NWDAF and the second analytics response received from the second NWDAF.
2. The method of claim 1 , further comprising:
receiving an analytics identifier registration from one or more NWDAFs prior to receiving the analytics request from the consumer, wherein the multiple NWDAFs are determined for the analytics request further based on the analytics identifier registration from the one or more NWDAFs.
3. The method of claim 2 , wherein the network entity receives multiple analytics identifier registrations from the multiple NWDAFs, and wherein the network entity determines the multiple NWDAFs from the multiple NWDAFs based on matching a corresponding analytics identifier in the analytics request to a supported analytics identifier for a corresponding NWDAF from the multiple NWDAFs.
4. The method of claim 2 , wherein each analytics identifier registration from an NWDAF includes one or more analytics identifiers for analytics that are supported by the NWDAF.
5. The method of claim 4 , wherein the analytics identifier registration further includes a supported area for each of the multiple NWDAFs, and wherein the analytics request further includes a location, and wherein the network entity determines the multiple NWDAFs for the analytics request further based on the location included in the analytics request and the supported area for the multiple NWDAFs.
6. The method of claim 1 , wherein the network entity comprises a central NWDAF or a network report function, and wherein the consumer of the wireless network comprises one of:
a core network entity,
an application function, or
an original equipment manufacturer.
7. An apparatus for wireless communication at a network entity of a wireless network, comprising:
a memory; and
at least one processor coupled to the memory and configured to:
receive, at the network entity, an analytics request from a consumer of the wireless network, the analytics request including a first analytics identifier and a second analytics identifier;
determine a first network data analytics function (NWDAF) based on the first analytics identifier indicated in the analytics request and a second NWDAF based on the second analytics identifier indicated in the analytics request;
forward, from the network entity, a request to multiple NWDAFs, wherein the network entity forwards a first request to the first NWDAF based on the first analytics identifier indicated in the analytics request and forwards a second request to the second NWDAF based on the second analytics identifier indicated in the analytics request;
receive multiple analytics responses including an analytics response from each of the multiple NWDAFs, including reception of a first analytics response from the first NWDAF and reception of a second analytics response from the second NWDAF;
combine the multiple analytics responses into a combined analytics response, wherein the network entity provides the combined analytics response to the consumer based on a combination of the first analytics response that the network entity received from the first NWDAF and the second analytics response that the network entity received from the second NWDAF; and
provide, to the consumer, the combined analytics response based on the combination of the first analytics response received from the first NWDAF and the second analytics response received from the second NWDAF.
8. The apparatus of claim 7 , wherein the at least one processor is further configured to:
receive an analytics identifier registration from one or more NWDAFs prior to reception of the analytics request from the consumer, wherein the at least one processor is configured to determine the multiple NWDAFs are determined for the analytics request further based on the analytics identifier registration from the one or more NWDAFs.
9. The apparatus of claim 8 , wherein each analytics identifier registration from an NWDAF includes one or more analytics identifiers for analytics that are supported by the NWDAF.
10. The apparatus of claim 9 , wherein the analytics identifier registration further includes a supported area for each of the multiple NWDAFs.
11. The apparatus of claim 10 , wherein the analytics request further includes a location, and wherein the at least one processor is configured to determine the multiple NWDAFs for the analytics request further based on the location included in the analytics request and the supported area for the multiple NWDAFs.
12. The apparatus of claim 7 , wherein the at least one processor is configured to receive multiple analytics identifier registrations from a plurality of NWDAFs, and determine the multiple NWDAFs from the plurality of NWDAFs based on match of a corresponding analytics identifier in the analytics request to a supported analytics identifier for a corresponding NWDAF from the multiple NWDAFs.
13. The apparatus of claim 7 , wherein the network entity comprises a central NWDAF or a network report function, and wherein the consumer of the wireless network comprises one of:
a core network entity,
an application function, or
an original equipment manufacturer.
