Unsynchronized service discovery

An electronic device comprising:

• a transceiver configured to, during an unsynchronized service discovery (USD) publish mode:
• transmit an unsolicited publish message, the unsolicited publish message indicating that further service discovery (FSD) is not required;
• and
• after transmission of the unsolicited publish message, monitor for receipt of a subscribe message from another electronic device;
• and
• a processor operably coupled to the transceiver, the processor configured to, upon receipt of a subscribe message indicating that FSD is not required:
• determine whether the subscribe message is relevant to an application of the electronic device;
• and
• in response to a determination that subscribe message is relevant:
• declare a replied event;
• generate a solicited publish message;
• and
• in response to declaration of the replied event:
• cause the transceiver to transmit at least one solicited publish message to the other electronic device;
• and
• declare that a USD publish instance has successfully concluded.

A method of operating an electronic device, the method comprising:

• monitoring for receipt of at least one publish message from another electronic device;
• upon receipt of a first publish message, determining whether the first publish message is relevant to an application of the electronic device;
• and
• in response to a determination that the first publish message is relevant:
• declaring a discovery result event;
• generating a follow-up message;
• and
• in response to the declaration of the discovery result event, transmitting the follow-up message to the other electronic device.
