9. An apparatus, comprising:

at least one processor;

at least one memory including computer program code;

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to;

compose in a wireless network, a wireless service discovery frame, the wireless service discovery frame including at least a service ID indicating support for providing proxy service discovery for other wireless devices operating in the wireless network and one or more indications whether the proxy service discovery is available for proxied publish services, proxied subscribe services, or both; and

transmit the composed wireless service discovery frame to the wireless network.

10. The apparatus of claim 9, wherein the service discovery frame includes a publish message indicating availability of proxy service discovery that includes the composed service ID.

11. The apparatus of claim 9, further comprising:

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to;

receive from at least one of the other wireless devices operating in the wireless network, a proxy registration request message in response to the transmitting of the wireless service discovery frame;

register the at least one of the other wireless devices operating in the wireless network, to provide a proxy publish service for the at least one of the other wireless devices; and

transmit to the at least one of the other wireless devices operating in the wireless network, a response message indicating initiation of proxy operation for the at least one of the other wireless devices, in response to the receiving of the proxy registration request message.

12. The apparatus of claim 11, wherein the proxy registration request message is for indicating that either the proxy registration request or a following message from the at least one of the other wireless devices operating in the wireless network, includes information on services to be subscribed or published by the wireless device as a proxy for the at least one of the other wireless devices.

13. The apparatus of claim 12, further comprising:

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to;

commence at least one of publishing and subscribing the services indicated by the proxy registration request, wherein the at least one of publishing and subscribing includes an indication that the at least one of published and subscribed services is proxied on behalf of the at least one of the other wireless devices operating in the wireless network.
