Description

The present disclosure relates to the field of network technology, and more particularly to the field of wireless access technology.

Wireless connection (Wi-Fi) peer-to-peer (P2P) technology has attracted a lot of attention due to its flexibility, remote connection capability, large amount of data transmission, etc., and has become an efficient and stable technology. Establishing a suitable and accurate connection method is an important issue. Wi-Fi P2P technology is applied to the connection between smart devices with android system.

Conventional Wi-Fi P2P generally has two topologies.

Mode 1 is service discovery (discoverServices), ie discovering local services. First, two terminals are set up as a service side and a client, and both agree on a specific name. The service side turns on the Wi-Fi P2P connection, creates a local service with that name, the client starts discovering the local service, and among the found services, the service side that should be connected by matching that particular name. , and then establish a connection.

Mode 2 is peer discovery (discoverPeers), ie discovering peers. First, two terminals are set as the service side and the client, and the service side activates the Wi-Fi P2P connection. The client does Peers discovery and gets a list of peripheral devices that have turned on Wi-Fi P2P. Next, the target service side device is found by scanning and connecting to the devices in the device list.

Mode 1 is inefficient and may not find the target device for a long time. Mode 2 must discover all peripheral devices that have turned on the Wi-Fi P2P connection, then poll to determine which device is the target serving device and establish the connection. Such methods are inefficient and have drawbacks.

Accordingly, as those skilled in the art will appreciate, various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Also, in the following description, descriptions of well-known functions and structures are omitted from the viewpoint of simplification.

An embodiment of the present disclosure provides a peer-to-peer connection method, which is applied to a peer-to-peer connected client terminal device. FIG. 1 is a flow chart of implementing a peer-to-peer connection method according to an embodiment of the present disclosure. It includes steps S101, S102, and S103.

In step S101, service discovery (discoverServices) and peer discovery (discoverPeers) are activated.

in step S102, if the instance name of the service terminal device matches the pre-arranged name in response to having previously discovered the service terminal device through service discovery, initiate a peer-to-peer connection with the service terminal device; Stores the identity of the service terminal device.

In step S103, when a device matching the identification information of the service terminal device exists in the peer device target list in response to the discovery of the peer device target list by peer discovery, peer-to-peer connection with the device is established. Start.

Optionally, before executing step S101, first, one of the two android devices supporting Wi-Fi P2P connection is set as a service terminal device, and a service side application (APP) is installed on the service terminal device. and install a client application (APP) on the client terminal device, with the other being the client terminal device.

A service-side application (APP) is launched, and the service-side application (APP) initializes the Wi-Fi P2P of the service terminal device. launching a client application (APP), the client application (APP) simultaneously launching a client terminal device's service discovery (discoverServices) discovery method and peer discovery (discoverPeers) discovery method, and discovering through the two types of discovery; That is, step S101 is executed.

Before establishing a connection, the client terminal device and the service terminal device pre-negotiate a name, for example, InstanceName.

Optionally, in said step S102, if the client terminal device has found a service terminal device (ServiceDevice) first, it obtains an instance name (InstanceName) and finds a Wi-Fi P2P device (wifiP2PDevice) target. If the instance name (instanceName) is a prearranged name and the device is not connected, a connection is initiated to the device. After the client terminal device establishes a Wi-Fi P2P connection with the service terminal device, the client terminal device stores identification information of the service terminal device, such as unique identification address information (deviceAddress).

That is, optionally initiating a peer-to-peer connection with the service terminal device when the instance name of the service terminal device and the pre-arranged name in step S102 match:
sending a connection request message to the service terminal device when the instance name of the service terminal device matches the pre-arranged name and the service terminal device is not connected;
and receiving a connection success message from the service terminal device.

Optionally, in said step S103, if the wifiP2PDevice target was previously discovered by peer discovery (discoverPeers), scan these devices and determine if the device matches the unique identification address information (deviceAddress) saved in said step. , and if the device is not connected, it initiates a connection to the device.

That is, optionally, if there is a device that matches the identification information of the service terminal device in the peer device target list in step S103, initiating a peer-to-peer connection with the device includes:
If there is a device matching the identification information of the service terminal device in the peer device target list and the device is not connected, sending a connection request message to the device;
receiving a connection success message from the device.

In some embodiments, the service terminal device simultaneously initiates monitoring for service discovery (discoverServices) and monitoring for peer discovery (discoverPeers), and any discovery causes the client terminal device to receive a connection request message sent by the client terminal device. When monitored, it establishes a connection with the client terminal device.

FIG. 2 is a flowchart of a peer-to-peer connection establishment process according to an embodiment of the present disclosure, including the following steps.

A client terminal device launches a client application (APP) and a service terminal device launches a service side application (APP). Here, the client terminal device is an android device with a client application (APP) installed, and the service terminal device is an android device with a service side application (APP) installed. Client terminal devices and service terminal devices launch their respective applications (APPs), and there is no particular context for launch times.

A service side application (APP) turns on the service terminal device's Wi-Fi P2P connection and creates a service side. A client terminal device initiates service discovery (discoverServices) and peer discovery (discoverPeers) and simultaneously by the service discovery (discoverServices) method and peer discovery (discoverPeers). The service terminal device also starts monitoring for the two discovery schemes. The execution of the operations by the service terminal device and the client terminal device are performed on both sides respectively, and there is no particular context between their execution times.

If the local service device was previously monitored by discoverServices, the client terminal device determines whether the name of the device matches the pre-stored InstanceName and whether the device is not connected. and if the names match and the connection is not in progress, the connection with the service terminal device is initiated. A service terminal device monitors the connection request by monitoring for discoverServices and receives the connection request. The connection process is completed when the client terminal device receives the successful connection callback function and locally caches the unique identification address information (deviceAddress) of the service terminal device.

When the Peers device target list is discovered by peer discovery (discoverPeers) first, a device that matches the cached unique identification address information (deviceAddress) is searched from the list, and the address information matches. If the device is found and the device is not connected, indicating that the device is the target service terminal device, the client terminal device initiates connection with the service terminal device. The connection process is completed when the service terminal device monitors the connection request by monitoring for discoverPeers, receives the connection request, and feeds back the connection success to the client terminal device.

As described above, if the client terminal device has already discovered a service terminal device through discoverServices and established a Wi-Fi P2P connection with the service terminal device, then establish a Wi-Fi P2P connection again later. When doing so, if a peer device target list is discovered by peer discovery (discoverPeers) first, a device that matches a pre-stored device address (deviceAddress) is searched from the list, and for the device A Wi-Fi P2P connection may be initiated without polling each device in the list, thus increasing the efficiency of establishing a P2P connection.

Furthermore, embodiments of the present disclosure provide a peer-to-peer connection method applied to a peer-to-peer connection type service terminal device. FIG. 3 is a flow chart of implementing another peer-to-peer connection method according to an embodiment of the present disclosure. It includes steps S301 and S302.

In step S301, monitoring for service discovery and monitoring for peer discovery are activated.

In step S302, feed back a connection success message to the client terminal device that sent the connection request message in response to the connection request message being monitored by the service discovery monitoring method or the peer discovery monitoring.

As described above, after the service terminal device turns on the Wi-Fi P2P connection function, it can monitor for two kinds of discovery methods at the same time. discoverPeers Regardless of which discovery scheme is chosen, in either case, connection requests of the client terminal device can be monitored.
