Problems solved by technology

[0006] However, low-power devices frequently perform service discovery within the discovery time window, which will increase power consumption. Therefore, they need a device that can provide more capabilities to help low-power devices enable several consecutive discovery time windows. Dormant within, and with minimal impact on business discovery

Embodiment 1

[0054] An embodiment of the present invention provides a caching service device selection method, which is applied to the main device side, such as figure 1 As shown, the method described in this embodiment specifically includes the following steps:

[0055] Step S101, storing cache service capability information and device information reported by each device providing cache service;

[0056] Specifically, in this step, after the service discovery time window starts, each device providing the cache service will actively report its own cache service capability information and device information to the master device. After receiving the information reported by each device providing the caching service, the master device stores it locally as the information basis for which devices can provide the caching service for the dormant device.

[0057] Step S102, when receiving a message requesting a caching service sent by a dormant device, include the caching capability information an...

Embodiment 2

[0068] The embodiment of the present invention provides a method for selecting a cache service device, which is applied to the dormant device side. The method on this side cooperates with the method on the master device side described in Embodiment 1 to realize the selection of a cache service device, as shown in figure 2 As shown, the method described in this embodiment specifically includes the following steps:

[0069] Step S201, sending a message requesting cache service to the master device;

[0070] Step S202, receiving a response message fed back by the master device;

[0071] Step S203, when the response message carries caching service capability information of a device that provides the caching service, send a caching service request message to the device; when the response message carries caching service capability information and When collecting device information, select a device that provides caching services according to the set selection strategy, and send a c...

Embodiment 3

[0077] An embodiment of the present invention provides a caching service device selection method, which is applied to the device side that provides caching services, such as image 3 As shown, the method described in this embodiment specifically includes the following steps:

[0078] Step S301, after the service discovery time window starts, report its own caching service capability information and device information to the main device, as the information basis for whether the main device or the dormant device selects this device as the caching service providing device;

[0079] Step S302: When receiving the caching service request message sent by the dormant device, respond to the caching service request message. Executing this step means that the device is selected as the cache service providing device, so it can receive the cache service request message sent by the dormant device. After responding to the message, the caching service can be provided for the dormant device. ...

Abstract

The invention discloses a cached business equipment selection method, equipment and system. The method comprises the following steps: storing cached business capability information and equipment information reported by equipment providing cached business; and when a cached business requesting message transmitted by dormant equipment is received, carrying the cached business capability information and the equipment information of the equipment providing the cached business in a response message to be transmitted to the dormant equipment. Main equipment disclosed by the invention stores related information of the equipment providing the cached business; the dormant equipment can simply query the main equipment when searching caching equipment; and a broadcast message is not needed, so that the network overhead is saved; and the query efficiency is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method, device and system for selecting cache service equipment. Background technique [0002] The Wi-Fi Alliance has developed a standard specification for a Neighbor Awareness Network (NAN). This specification aims at low power consumption and fast discovery of services provided by surrounding devices. [0003] The NAN technology uses time synchronization to perform service discovery within the agreed discovery time window. Two types of messages are defined in the current standard: Beacon and service discovery. Beacon Beacon is divided into synchronization Beacon and discovery Beacon. Discovery Beacon is transmitted outside the discovery time window and is used to discover NANCluster (NANCluster is a group composed of multiple devices. In this group, the time is synchronized and the same time window is used for service discovery); synchronization Beaco...
