Background technique

In the field of mobile communication, with the development of technology and applications, the open service interface technology makes the next generation network a network that can provide rich personalized services, and future mobile terminals must have an open architecture. However, from the current point of view, various functions of the terminal are relatively concentrated, such as camera, display, audio, microphone, and earphones are all integrated into one device, and the terminal's access, processing, and display capabilities are also very limited. When a certain service requires higher terminal display capabilities and different access capabilities, such terminals must have great limitations on the development of this service. Therefore, the relative lag of terminal technology has become the bottleneck of business development: the capability is single, the structural system is closed, the scalability is not strong, and it is not suitable for the provision of multimedia data services.

Future terminals should be functionally componentized, interface standardized, protocol layered, and have an open architecture. Functional componentization is to divide the terminal into functional components such as network access, terminal input, display output, and data processing according to its business support capabilities. Each functional component is based on a dynamic and intelligent scheduling control strategy in accordance with the provisions of standard interfaces and layered protocols. , combined or separated to form a whole terminal. We call this terminal architecture a unified service terminal. In this way, the unified service terminal is a whole for service applications, which is formed by aggregation of different devices connected through the network.

Detailed ways

The unified service terminal system of the present invention is a virtual terminal formed by aggregating devices with one or more capabilities by using wireless or wired personal domain connection technology according to user requirements. The unified business terminal system constructed is a distributed terminal system.

In the present invention, the unified service terminal is abstracted into a logical system structure from a functional point of view. As shown in Figure 1, the unified service terminal system includes a framework function module, an execution environment function module, an aggregation control function module and multiple capabilities Server function module.

The framework function module is used to realize the central management and control function of the unified service terminal, which is responsible for controlling the aggregation and separation of each device in the unified service terminal system, and managing the information, user information and business information of all distributed devices in the unified service terminal system , evaluate the capability resources of the unified service terminal according to the business requirements, provide the best capability provision scheme for the business, and configure the execution environment.

The execution environment function module manages and coordinates the specific scheduling and collaborative work of the capability servers of the unified service terminal system, and provides a unified terminal operation interface for services.

The aggregation control function module is responsible for managing the capability collection and device status of each distributed device, and mainly controls the aggregation and separation process of each distributed device in the unified service terminal.

The capability server encapsulates various capability features of the unified service terminal system, and can conveniently provide capability services for services. In the present invention, one capability server only encapsulates one capability feature.

The method for building a unified service terminal involved in the present invention needs to install a series of software on the device, and these software include framework function software, aggregation control function software, execution environment software and capability server software. The framework function software realizes the function of the framework function module, the aggregation control function software realizes the function of the aggregation control function module, the execution environment software realizes the function of the execution environment function module, and the capability server software realizes the function of the capability server function module;

Equipment installed with framework function software, aggregation control function software, execution environment software, and capability server software has framework functions, execution environment, aggregation control function, and capability server, and becomes a class of equipment. That is to say, a type of device described in the present invention is a device having a framework function, an execution environment, an aggregation control function, and a capability server. A type of device can be used as the main control device in the unified service terminal system.

Devices installed with aggregated control function software and capability servers only have aggregated control functions and capability servers, and are Class II devices. That is to say, the second-type device mentioned in the present invention refers to a device that only has an aggregation control function and a capability server. Class II equipment cannot be used as the main control equipment of the unified service terminal.

The master control device involved in the present invention is the central control device in the unified service terminal system, only one type of device can serve as the master control device, and there is only one master control device in each unified service terminal system.

The method for constructing a unified service terminal system according to the present invention will be described below with reference to FIG. 2 .

In the present invention, the unified service terminal system aggregates devices with several kinds of capabilities together to form a virtual terminal, selects one type of device as the main control device, and constructs a unified service terminal system. This type of device may be a handheld device or a fixed-position device with relatively strong computing capabilities, which is selected by the user. The method comprises the following specific steps:

(1) The user selects one of the first-class devices, and runs the framework function module and the execution environment module on the first-class device, so that the first-class device becomes the main control device of the unified service terminal system to be constructed.

When running the framework function modules and execution environment modules on the type of equipment, several capability servers contained in the type of equipment are first aggregated on the type of equipment, thus becoming a unified The main control device of the business terminal system.

(2) The main control device of the unified service terminal system sends a broadcast message to notify the surrounding environment of the existence of the unified service terminal system and its own description information. .

The broadcast message is a self-describing information of the unified service terminal system, the purpose of which is to let the equipment receiving the broadcast message in the surrounding environment know the existence of the unified service terminal system and know the unified service terminal system from the information. The location and access method of the business terminal system, etc. Its content may include the ID and device type of the master device, etc. Wherein, the device type indicates whether the device is a first-class device or a second-class device.

(3) After receiving the broadcast message, the surrounding Class I or Class II devices send an aggregation request message to the frame function module of the master device.

After receiving the broadcast message, the first-class equipment or second-class equipment judges whether it has joined other unified service terminal systems. If not, send an aggregation request message to the main control device, and save information such as the ID and type of the main control device, indicating that the device requests to join the unified service terminal system indicated by the broadcast message. If the device has already joined other unified service terminal systems and cannot join the unified service terminal system to be built, the device will not respond to the broadcast message of the master control device.

(4) The main control device authenticates the device requesting aggregation, and returns an authentication result to the device requesting aggregation. Then, the aggregation device and the main control device that have successfully authenticated generate a capability service key during the authentication process, which is used for encryption and decryption when the capability server calls.

The authentication process described in this step includes the following steps:

a. The framework function module of the main control device randomly generates an authentication code, sends the authentication code to the device requesting aggregation, and generates a key corresponding to the authentication code through an authentication algorithm;

b. After receiving the authentication code, the device requesting aggregation generates a response key through the same authentication algorithm, and sends the response key to the master device;

c. After receiving the response key, the master device compares the key with the response key, and if the two are the same, it returns an authentication success message to the device requesting aggregation; The device returns an authentication failure message;

d. The master control device and the request aggregation device that have successfully authenticated use the authentication code to generate a capability service key through the same encryption algorithm, which is used for encryption and decryption when calling the device capability server.

(5) The device requesting aggregation judges the authentication result. If the authentication is successful, the device requesting aggregation sends the self-description information of the device to the main control device, registers the device information to the framework function module of the main control device, and at the same time informs the capability service key of the device to each capability server. The master device returns an aggregation success message to the device requesting aggregation. If the authentication fails, the device requesting aggregation cannot join the unified service terminal system, and the device clears the previously stored self-description information of the unified service terminal system that sends the broadcast message.

The self-describing information of the device includes: device ID, device type, framework function information, execution environment information, capability information, and the like. The main control device saves the self-description information of the device in the framework function module, and the framework function module manages the self-description information of the devices in the unified service terminal in a unified manner.

(6) Other devices add themselves to the unified service terminal system where the main control device is located through the same aggregation process as above, thereby enriching the capabilities of the unified service terminal system.

Through the above method, a distributed unified business terminal system is constructed and enriched, which presents business applications and the external environment as a whole, and directly interacts with business applications through the frame function modules of its main control equipment and execution environment modules, through Provide business applications with an open unified interface to support business applications calling the capabilities of the unified business terminal system, thereby providing corresponding service effects and user experience.

According to the present invention, a method for deploying and executing services through framework function modules and execution environments in the unified service terminal system is also provided, shielding each distributed capability server, thereby providing unified service capability support for service applications. In addition to comprising the above-mentioned steps of building a unified service terminal system, the method also includes the following steps:

(1) After the service is started, a broadcast message is released, and after receiving the service message, the framework function module of the main control device of the unified service terminal system returns a confirmation message to the service and initiates a service authentication process;

(2) After the business has passed the authentication, register its own information with the framework function module of the master control device that has successfully authenticated, and propose business capability requirements;

(3) The frame function module of the unified service terminal system adapts the best capability provision plan for the service according to the service capability requirement and sends it to the service.

(4) The service receives the capability provision plan issued by the framework function module of the main control device of the unified service terminal system, and makes a judgment. If it finds that its own capability requirements can be implemented based on the capability solution, it returns the capability call confirmation information. If not, the business application can choose to terminate the application program, or suspend and wait for the capability update of the unified service terminal system to meet the capability requirements of the business application;

(5) After receiving the capability invocation confirmation message, the unified service terminal system configures the execution environment, sends execution environment configuration success information to the service application, and sends the corresponding capability invocation command.

(6) The service calls the capability server through the capability call command; the service sends the capability call command to the execution environment, executes the environment analysis capability call command, and implements the call to the distributed capability server through the capability server agent in the execution environment, thereby The distribution and heterogeneity of the capability server is shielded from the business.

(7) When the service application ends, submit a service end request to the execution environment. According to the request, the execution environment sends a call end command to each capability server through the capability server agent, and each capability server ends the call operation according to the command. At the same time, the execution environment automatically releases the relevant capability server proxy, deletes the corresponding capability call and proxy mapping table, notifies the framework of the business end message, and the framework clears the corresponding information of the business. Finally, the framework sends a confirmation message to the business application. The business application exits normally.

The business authentication steps include:

a. The framework function module of the main control device randomly generates an authentication code, sends the authentication code to the service, and generates a key corresponding to the authentication code through an authentication algorithm;

b. After receiving the authentication code, the service generates a response key through the same authentication algorithm, and sends the response key to the framework function module;

c. The framework function module compares the key and the response key according to the received response key. If the two are the same, the authentication success message will be returned to the service; if the two are not the same, the authentication failure message will be returned to the service ;

In the step (5), it involves configuring the execution environment between the business application and the distributed capability server. distribution and heterogeneity.

The step of configuring the execution environment includes: after the framework receives the confirmation information of the capability provision scheme from the business application, submits the information of each capability server in the capability provision scheme and the corresponding capability service key to the execution environment in the unified business terminal system module, the execution environment module generates the capability server agent for each capability server corresponding to the capability provision scheme after receiving the information, and saves the capability call command and proxy mapping table in the execution environment to clarify the capability call command and capability server in the execution environment. The mapping relationship between the agent, the capability server and the capability service key, and the execution environment parses the capability invoking command according to the mapping relationship.

The following figure illustrates the mapping relationship among the capability call command, capability server agent, capability server and capability service key in the execution environment

Ability to invoke commands UI video capability server UICS VideoCS Capability Server Proxy UICS proxy VideoCSproxy Capability service key Key1 Key2

In the step (6), the business sends a capability call command to the execution environment. After the execution environment receives the capability call command, it will know the capability server proxy of the capability server that needs to be called by searching the capability call command and the proxy mapping table. ID, and send the corresponding invocation command to the identified agent. The capability server agent can automatically find the address of the capability server it acts as agent, and pass the corresponding commands and configuration parameters to the capability server, and establish a two-way communication relationship with the capability server, and constantly transmit the information of both parties.

During the transmission of the bidirectional data flow from the capability server agent of the execution environment to each corresponding capability server, it needs to be encrypted according to the capability service key corresponding to each capability server acquired during the process of configuring the execution environment. The receiver (capability server or capability server proxy) uses the same capability service key to decrypt the service data flow, thereby providing corresponding security guarantees from the perspective of data flow transmission.
