The basic idea of the present invention is as follows: When the terminal determines that the user cannot complete the service requested by the user independently, the AP searches for the AP of the surrounding network, determines whether there is a network that can assist the terminal to complete the service, and when the terminal exists, the terminal accesses the network that can assist the terminal to complete the service. And the network that can assist the terminal to complete the service cooperates to complete the service; when not present, the terminal searches for the service capability information of other peripheral terminals, determines other terminals that can assist the terminal to complete the service, and negotiates with other terminals, and the terminal and The other terminals searched for form a service network to jointly implement the service.

In the present invention, the most common short-range wireless communication protocol WIFI is used for description. It should be noted that those skilled in the art can use other short-range communication protocols to perform appropriate modifications according to the method of the present invention. In the WIFI protocol, the service and capability information are broadcasted by multiplexing the WIFI protocol Service Set Identifier information. Therefore, the present invention redesigns the SSID part to associate the service group in the form of a key value table. The terminal information attribute value required by the network is added to the beacon frame, and the interaction of the terminal information capability and the service network information is integrated. FIG. 1 is a schematic diagram of a WIFI beacon frame format according to an embodiment of the present invention. As shown in FIG. 1, the present invention divides a 32-byte (Byte) SSID information into the following parts:

Service Name: 2Byte, which identifies the types of services required by the terminal. According to the requirements and functions of the collaborative services, it is divided into bandwidth aggregation class, content collaboration and interaction class, terminal capability provision class and service identifier provision. The bandwidth aggregation service refers to a service in which a terminal provides a large file or a video that is limited by its own bandwidth and cannot complete the user's demand. The service transmission capability of the other terminal is required to aggregate the bandwidth of multiple terminals for service download. Multi-terminal collaboration scenarios are more common types of services; content collaboration and interaction classes mean that multiple terminals share their respective terminal content. Or through the interoperability to complete the interactive process, such as multi-player games, multi-person collaborative work, etc.; Terminal capability-providing service refers to the completion of one or more functions by means of the unique capabilities of the peripheral terminals, which may be their own terminals. Having or not sufficient, such as the printing capability, external capacity, display capability, etc. of the terminal; providing service identification, providing service provision on behalf of the terminal, and common such as public terminals are generally used as service providers.

Service function parameter: 6Byte. If the service name is a specific service category, the part is further constrained by the foregoing service, such as service type, service function description information such as service quality requirements, delay requirement, service running environment, etc. If the service name is a service identifier, this part is the service capability that the terminal can provide. It is not specifically limited in the present invention, and an API (Application Programming Interface) interface is provided for those skilled in the art to define according to a specific service type.

Capability attribute name: 4Byte, describes the capability attributes of the terminal, including terminal type, supported communication protocol, hardware configuration, operating environment, bandwidth, computing power, transmission capability, and capabilities (such as data acquisition, information processing, printing, and external Put, show, etc.).

Capability attribute value: 4Byte, the attribute value corresponding to the capability attribute. If the attribute does not exist, the default tag is used.

It should be noted that if the service name is a specific service category, the capability attribute name and the capability attribute value represent the terminal capability information required for requesting the service; if the service name is the service identifier, the capability attribute name and the capability attribute value represent the terminal capability information of the terminal. . Due to the limitation of byte space, the capability attribute in the broadcast information adopts three values that the service provider or the requester is most concerned about, for example, less than three adopt the default value.

In the present invention, the terminal needs to perform capability information broadcast using a beacon frame carrying the SSID shown in FIG. 1. Similarly, the AP also broadcasts the capability information of the network to which it belongs. Specifically, the AP broadcasts the capability information of the network node and the server in the network to which the network belongs, as the capability information of the network to which it belongs. In this way, between the terminal and the terminal, between the terminal and the AP, the broadcast message can be confirmed. The other terminal and the capabilities supported by the AP are determined, so that when it is determined that the user cannot support the service requested by the user, the service requested by the user is integrated with the network to which the other terminal or the AP belongs.

The present invention will be further described in detail below in conjunction with the drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

FIG. 2 is a flowchart of a service providing method according to an embodiment of the present invention. As shown in FIG. 2, a service providing method according to an embodiment of the present invention includes the following steps:

Step 201: The user terminal sends its own service request.

Step 202: The terminal determines, according to the requested service information, whether the service can be completed independently. If yes, step 203 is performed, and step 204 is performed.

In this step, the terminal's judgment on the service needs to be judged by the user's usage habits, preferences, and service data provided by the server, and different users of the same service may have different service requirements.

Step 203: The terminal completes service provision by using its own capabilities.

Step 204: Encapsulate the service requirement information into the SSID, including selecting a corresponding service name according to the service type, encapsulating the user service requirement information into the service function description, and encapsulating the terminal attribute information according to the requirement for providing the service terminal. Of course, the above SSID also carries the capability information supported by the terminal. The capability information includes at least one of the following information: a name of a service required by the terminal, a service function parameter, a capability attribute name, and a capability attribute value.

Step 205: Search for the neighboring network AP, check the SSID information of each AP, check whether there is a service network providing the required service in the surrounding area, if yes, go to step 206, otherwise go to step 208.

Step 206: Negotiate according to the service requirement information and the service capability information provided by the service network, and determine whether the network meets the user service requirement. If the network is not satisfied, mark the network as a non-service network, and go to step 205. Otherwise, go to step 207.

Here, it is determined whether the network meets the user service requirement, mainly according to the service type of the service demand, the service quality requirement, the delay requirement, the service operation environment, etc., to determine whether the network has the capability, and if so, the terminal access In the network, the network server is based on the network. The capability information of the node determines a node that interacts with the terminal for the terminal, and allocates resources for the terminal, and the collaborative terminal implements the service requested by the user. If the terminal needs to print the service, and the terminal itself is not connected to a printing device such as a printer, the terminal can pass the relevant setting requirements of the printing service.

The SSID information is broadcast, and a certain network has a printing function, and after the terminal accesses the network, it determines whether the printing device in the network satisfies the printing requirement of the terminal according to the printing service of the terminal and the service demand parameter thereof, and satisfies the terminal. When printing business needs, provide printing services for the terminal.

Similarly, the service of the terminal side user may also include file conversion, file transfer, and the like. Those skilled in the art should understand that it is easy to implement service negotiation according to service requirements. Since there are many types of services involved in the present invention, it is impossible to enumerate the process of each service negotiation, and those skilled in the art should understand that this does not mean that These services cannot be implemented by the present invention. For any existing business, as long as the relevant requirements of the business are determined, the corresponding business negotiation can be realized according to the parameters and attributes of the business requirements.

Step 207, completing automatic configuration and joining the service network, and interacting with other nodes in the network to complete service provision.

Step 208: Configure the node into an Ad hoc mode, obtain the SSID information of the peripheral terminal through two-way interaction, and obtain a terminal that can provide services or request the same service by parsing the SSID information.

In this step, the reason is configured as Ad hoc mode, so that other terminals can search for their own service requirements or provide service capability information before establishing a connection.

Step 209: A plurality of terminals capable of providing the service negotiate according to the terminal capability, and select an optimal node as a central node to form a service network.

In this step, in the election process of the central node, the weighted sum is used according to the value of the terminal capability attribute in the SSID, and the terminal with the largest weighted sum is selected as the central node.

Here, the reason why the terminal of the central node is selected is mainly based on the convenience of interaction. If a terminal can carry more processing of the service, it can be used as the center of communication, thus, When each terminal performs service negotiation, it can reduce the amount of data negotiated by the service. The manner of service negotiation is basically the same as the manner of service negotiation between the terminal and the network to which the AP belongs.

In the present invention, the services negotiated by the terminal mainly include multi-player games, etc., for example, when the terminal user needs to perform multi-player games, the terminal can search for the neighboring terminal through the terminal, and when searching for multiple terminals, the terminals are The capability negotiation is performed to determine the central node terminal and perform the game cooperatively. The implementation of the collaborative game service is similar to the implementation of the multiplayer game supported by the existing Internet, except that the multiplayer game supported by the present invention needs to implement one of the terminals as a central node terminal.

Step 210: The AP node of the service network periodically updates the SSID information according to the capability information of the node and the server in the network, and the service network can provide the service information.

Through the above methods, the terminal capability in a certain area can be autonomously aggregated, and the unified service provision is completed through cooperation of multiple terminals.

The service discovery and networking method of the present invention can complete the service discovery and network configuration autonomously in the user terminal to enter the service terminal distribution area, and finally complete the service provision process. Since the terminal discovery and service discovery are performed before the terminal is connected, the transparent access of the service capability is realized, the cumbersome process of user configuration is omitted, and the user's optimal service experience can be realized.
