Problems solved by technology

Low-power devices frequently perform service discovery within the discovery time window, which will increase the power consumption of the device, and if the low-power device is made to sleep within the discovery time window, other devices will not be able to discover the services it provides

Embodiment 1

[0082] This embodiment provides a service discovery method executed on the side of a dormant device. figure 1 is a flow chart of the service discovery method according to the first embodiment of the present invention.

[0083] In step S110, the dormant device discovers the proxy device according to the received service provisioning proxy message before going to sleep.

[0084] The device that initiates the provisioning service proxy message is a proxy device. Therefore, in the received message, search for the service proxy message of the provisioning class whose attribute identifier represents the proxy service and whose type is the provisioning class; since the source device in the provisioning service proxy message The address is the device address of the proxy device, so the device address of the device that initiates the provisioning service proxy message, that is, the device address of the proxy device, can be determined according to the service provisioning proxy message...

Embodiment 2

[0094] This embodiment provides a service discovery method executed on the proxy device side. figure 2 is a flow chart of the service discovery method according to the second embodiment of the present invention.

[0095] Step S210, receiving a request-type service agent message sent by unicast from the dormant device before the dormancy.

[0096] Before receiving the request service proxy message, it also includes: broadcasting the provision service proxy message to all devices in the NANCluster, so that after the dormant device receives the provision service proxy message, it can discover the proxy device according to the provision service proxy message .

[0097] Step S220, storing the proxy information of the dormant device included in the request service proxy message, where the proxy information includes: service information of the dormant device.

[0098] Since the message content of the request service proxy message is the proxy information of the dormant device, the...

Embodiment 3

[0109] This embodiment provides a service discovery method performed on a common device side. image 3 is a flow chart of the service discovery method according to the third embodiment of the present invention.

[0110] Step S310, discovering the proxy device according to the received service provisioning proxy message; wherein, the service provisioning proxy message includes service information of the dormant device.

[0111] Step S320, sending a unicast service proxy message including service information of the dormant device to the proxy device.

[0112] Step S330, receiving a response-type service proxy message including proxy information of a dormant device sent by the proxy device in unicast.

[0113] Proxy information is what a sleepable device stores to a proxy device before it goes into sleep.

[0114] The agent information includes: device information, service information and sleep time of a sleepable device.

[0115] After receiving the response service proxy mes...

Abstract

The invention discloses a service discovery method and apparatus. A service agent message used for achieving service agent is created; before the dormancy of a dormant device, the dormant device interacts with an agent device based on the service agent message, and the agent information is stored in the agent device; and during the dormancy of the dormant device, a common device discovers services provided by the dormant device through the agent device. By adopting the service discovery method and apparatus disclosed by the invention, the dormant device can sleep in a discovery time window to reduce the power consumption of the dormant device and generate no influence on the service discovery of other devices to the dormant device.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a service discovery method and device. Background technique [0002] The Wireless Fidelity (Wi-Fi for short) alliance has developed a standard specification for a Neighbor Awareness Network (NAN for short). This specification aims to enable devices to quickly discover services provided by surrounding devices. [0003] The NAN technology uses time synchronization to perform service discovery within the agreed discovery time window. Currently, two types of messages are defined in the standard: Beacon and service discovery messages. [0004] Beacon Beacon is divided into synchronous Beacon and discovery Beacon. The discovery Beacon is transmitted outside the discovery time window and is used to discover the NAN cluster (NANCluster). Among them, the NANCluster is a group composed of multiple devices, and the devices in the group are synchronized in time and use the...
