Description

A device service calling method and device based on Alljoyn gateways

technical field

The present invention relates to the technical field of communication, in particular, to a method and device for invoking equipment services based on Alljoyn gateways.

Background technique

Alljoyn (Alltojoininthefun, Alljoyn communication protocol) is a point-to-point communication framework between devices based on C/S architecture, which consists of a bus daemon (BusDaemon) and terminal nodes. BusDaemon is responsible for message routing between terminal nodes, service discovery and other functions. The terminal node refers to the application program running on the device, which needs to connect to the BusDaemon after startup. If the terminal node provides a service, it will register a service name with the BusDaemon, which will be broadcast by the BusDaemon. As a client, you can find the service through the service name, and complete the specified function through remote calls.

In order to enable Alljoyn to better support smart home scenarios, Alljoyn's Smarthome service (Smarthomeservice) proposes the concept of centralized management, that is, SmartHomeservice runs on the gateway, and other Alljoyn devices register the services they provide with the gateway. All communication between Alljoyn devices goes through the Alljoyn Gateway. The Alljoyn gateway manages all registered Alljoyn devices in a unified manner. Thus, Alljoyn's point-to-point distributed communication mode is extended to a centralized communication mode, while ensuring the security of the communication process. However, this centralized communication mode can only communicate between devices based on the premise that all devices must first be registered on the same gateway. If there are more than two such gateway devices in the network, then there is no way to communicate between devices registered on different gateways, which obviously does not meet the smart home scenario.

detailed description

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

The main idea of this article is to ensure that the Alljoyn gateway realizes centralized control, and realizes that the machines and devices registered on different gateway devices have the ability to communicate with each other, and broadcasts the registration invitation message containing its own network address and password to the machine through the gateway device Device, so that the machine equipment originally registered on different gateway devices can be automatically registered on the same gateway device, so that the two machine devices that need to communicate can have communication capabilities.

The client device used herein refers to the machine device that is the source of the request message, and the server device refers to the machine device that is the callee with the target service that needs to be invoked by the request message.

The registration information table of the gateway device in this paper contains at least the network address of the registered device and the services it has. The gateway device can find the network address of the registered device and the services of the registered device by querying the registration information table.

As shown in Figure 1, a device service invocation method based on Alljoyn gateways is disclosed, which is used for the first gateway device registered with a client device, including:

S11. Receive a request message sent by the client device;

S12. If it is judged that the registration device of the gateway device does not provide the target service to be invoked by the request message, broadcast a registration invitation message carrying the identifier of the target service and the network address of the gateway device to the outside;

Wherein, the identifier of the target service is extracted from the request message by parsing the request message; in addition, the request message may also be used directly, for example, the request message is included in the registration invitation message;

S13. Receive registration information of a server device having the target service, and establish a connection with the server device;

Wherein, the server device is a device that sends registration information to the first gateway device according to the registration invitation message and can provide the target service.

S14. Invoking the target service on the server device according to the request message.

By broadcasting its own network address and temporary registration password between gateway devices, machines and devices registered on different gateway devices can be automatically registered on the same gateway device, so that machines and devices registered on different gateways can communicate with each other and inherit The concept of centralized management is introduced, so that the machine equipment must access other machine equipment through the gateway device, so as to ensure the security and stability of the system.

In some illustrative embodiments, judging whether the registration device of the gateway device provides the target service that the request message needs to invoke specifically includes: through the identifier of the target service, searching for the existence of If the registered device with the target service does not have the registered device with the target service, it is determined that the registered device of the gateway device does not provide the target service.

The initiator in the above process does not need to know the network address of the target device (server device) of the request message. When the current gateway device cannot know the situation of the target device, the current gateway device will broadcast the registration invitation message to the outside, and other gateways will send the registration invitation message to the outside world. The target service makes a judgment, so as to achieve the purpose of automatically finding the target device.

In a safe situation, the normal password of the first gateway device can also be used directly.

In some demonstrative embodiments, before broadcasting the registration invitation message including the temporary registration password, the method further includes: generating the temporary registration password.

In some demonstrative embodiments, after invoking the target service on the server device according to the request message, it further includes: receiving a result notification message sent by the server device, and sending the result notification message sent to the client device.

Among them, the result notification message can be used to inform the client device that the invocation of the target service has been successful, or it can be the parameter data after the server device has executed the service call, for example, the temperature of the air conditioner is lowered by 4°C through the smartphone, and the air conditioner After the service is executed, the expected adjustment time will be used as the result notification message; in addition, it can also be information or data requested by the client device from the server device, for example, a smartphone uses an air conditioner to obtain the current indoor temperature.

In some demonstrative embodiments, after invoking the target service on the server device according to the request message, the method further includes:

1) cancel the registration information of the server device on the gateway device; or,

2) Deregistering the registration information of the server device and the temporary registration password on the gateway device.

The procedure in 1) above is applied when the first gateway device is in an open access mode, and the process in 2) is applied in a case where the first gateway device is in a non-open access mode.

In some demonstrative embodiments, the logout is triggered by receiving a confirmation message sent by the client device to indicate that the client has successfully received the result notification message, that is, after receiving the confirmation message, the logout is performed Registration information, and a temporary registration password.

S22. If the server device with the target service identifier is found in the registration information table of the gateway device, send the network address of the first gateway device to the server device.

Wherein, if the server device with the target service identifier is not found in the registration information table of the gateway device, the registration invitation message is continuously broadcasted with the gateway device as the sending source to expand the broadcast range;

In some demonstrative embodiments, the registration invitation message further includes a temporary registration password of the first gateway device.
