Description

Framework system for cooperation of mobile devices and method for cooperation of mobile devices

The present invention relates to a framework system for cooperation between mobile devices and a method for cooperating between mobile devices, and more specifically, it is possible to combine resources of several mobile devices into one virtual device so that it can be used as a local mobile device. A framework system and method are disclosed.

Today's mobile devices are becoming smaller, higher in performance and supporting a variety of features. As a result, it is common to use mobile devices, and it is easy to see how many mobile devices you can carry with you. The use of multiple devices means that the number of memories to be managed increases, and as memory technology advances, management becomes more difficult as the storage space grows.

Today's mobile services are divided into two streams: convergence and divergence. Convergence is one of the biggest trends in IT today. It combines several services into one, so users can get most of their services with just one device. Divergence focuses on the functionality of the service in the opposite sense, and in some cases, divergence is more appropriate for users than convergence. Moreover, most of these services are hardware dependent, so if new services emerge, they may not be available on converged devices. For example, a mobile device released in the absence of DMB service is inevitable for hardware replacement for DMB service, and without a GPS interface, a navigation program cannot be used even if it has a high-performance processor and a large LCD. In this case, if the hardware is not supported, you usually have to buy new hardware.

In addition, the use of various mobile devices often overlaps the functions of each device, which is not efficient in terms of price. In other words, each person usually has several mobile devices, and most of the functions of each mobile device are duplicated. MP3 players, for example, have features such as MP3, video, radio, and recorder, which also have cell phones and support PDAs and PMPs. Most people have these redundant features unnecessarily, which leads to an unnecessary cost increase.

The technical problem to be achieved by the present invention is to provide a framework system and a method of cooperation between mobile devices for cooperation between mobile devices that can combine the resources of several mobile devices to use as if it is a local mobile device.

In order to solve the above technical problem, a framework system for cooperation between mobile devices according to the present invention is a component included in a service consumer which is a device requesting a service supported by another device, and devices around the service consumer. A service discovery protocol component that collects service lists from the network; A database manager for storing the found service lists and retrieving a service list upon request of a service API of the service consumer; And a service transmission / reception protocol component that sends a service request to a corresponding device and receives a service response from the corresponding device according to a request of the service API, and is provided in a service provider which is a device that provides its own service to another device. In particular, a service discovery protocol component for providing a service list of the service provider to the service consumer; A service manager requesting a service from a service API of the service provider according to the service request; And a service transmission / reception protocol component for transmitting a service response according to the service request to the service consumer.

Here, the service discovery protocol component included in the service consumer may send a service discovery request to the peripheral devices and receive a service discovery response including a service list from the peripheral devices.

In addition, the service discovery request may be transmitted in a broadcasting manner.

The service consumer may further include a storage in which the collected service lists and a service description corresponding thereto are stored.

The framework system may further include a log manager that records an entire operation executed in the service consumer or the service provider as a component included in the service consumer or the service provider.

The service discovery protocol component included in the service provider may receive a service discovery request from the service consumer and transmit a service discovery response including a service list of the service provider to the service consumer. have.

Here, the service discovery response may be transmitted in a unicast manner.

The framework system may further include a service database manager which stores a list of services supported by the service provider as a component included in the service provider.

In addition, the framework system may further include a scheduler configured to schedule transmission of the service response of the service transceiving protocol component as a component included in the service provider.

In order to solve the above technical problem, the method of cooperation between mobile devices according to the present invention comprises: (a) collecting and storing a service list from neighboring devices in a service consumer which is a device requesting a service supported by another device; ; (b) retrieving the stored service list according to a request of a service API and, according to the result, transmitting a service request to a service provider which is a device that provides its service to another device; And (c) generating, at the service provider, a service response according to the transmitted service request and transmitting the service response to the service consumer.

Here, the step (a) may include transmitting a service discovery request from the service consumer to the peripheral devices; Generating, by the device receiving the transmitted service discovery request, a service discovery response including its service list and transmitting the generated service discovery response to the service consumer; And receiving the transmitted service discovery response and storing a service list included therein.

In this case, the service discovery request may be transmitted by broadcasting, and the service discovery response may be transmitted by unicast.

In addition, in the step (c), the service provider may generate service data through its service API according to the transmitted request and generate the service response including the service data.

Also, in the step (c), the service response may be temporarily stored and then transmitted to the service consumer according to scheduling.

According to the present invention described above, it is possible to combine the resources of several mobile devices into one virtual device so that it can be used like a local mobile device. Therefore, it enables more efficient use of storage space, enables the equal use of resources, and integrates even through devices that cannot be supported by hardware or support only one or two services. Can provide services. In addition, it is useful to design low-cost, high-efficiency devices because the network can use unique functions from other devices without adding special devices, and the duplication of functions can be avoided.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description and the accompanying drawings, substantially the same components are denoted by the same reference numerals, and redundant description will be omitted. In addition, in the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a reference diagram schematically illustrating the concept of the present invention. As shown in FIG. 1, in the present invention, the unique functions of each mobile device (for example, DMB receiver reception function of a DMB receiver, telephone function of a mobile phone, and camera function of a high performance camera) may be combined and used in another device. I want to be able to. In the embodiments of the present invention described below, it is assumed that a user owns several mobile devices having different functions, and that each mobile device is connected to each other through a wireless network. Hereinafter, a device requesting a service supported by another of mobile devices will be called a service consumer, and a device providing its service to another device will be called a service provider. .

2 and 3 are structures of a framework system for cooperation between mobile devices according to an embodiment of the present invention, and show structures of a service consumer side and a service provider side, respectively. The service consumer becomes the device to be used and the service provider becomes a cooperative device that provides its service through the wireless network. The service provider defines the name, type, and data format of the service in order to provide its own service to other devices, and provides it when a request is made from nearby devices. The service consumer has an API for retrieving the service list of other devices available around and using the service of other devices as its own service. The roles of service consumer and service provider may be interchanged.

The framework system according to the present embodiment is divided into components for operation and protocol components for communication between mobile devices. The components are classified into three hierarchical layers, which are an interface layer, a core layer, and a communication layer, as shown.

The interface layer is located between the service application and the core layer, and connects the service application and the framework. At this layer, the device communicates with the service using the service API. A module is then loaded to manage the service API and to translate messages received from the service API. The components of the core layer contain the core functions of the device, manage the entire framework, and control operations. The communication layer has components for communication between devices, which deliver the delivered message to the upper layer.

Now, the service consumer side structure of the framework system according to the present embodiment will be described in detail with reference to FIG. 2. As shown, the service consumer side includes a message parser 111 and a service manager 113 as components of an interface layer, a log manager 115 and a service list manager as components of a core layer. manager 117, service consumer controller 119, database manager 121, task manager 125, and service discovery protocol components as components of the communication layer. And a service transfer / receiver protocol component 129 are provided. The service consumer includes components for discovering service lists of peripheral devices.

The service manager 113 requests a service from the service API and notifies the message parser 111 and the service consumer controller 119 of the result. The message parser 111 parses the input API parameters and converts them into an understandable format for the framework.

The service consumer controller 119 controls the entire components and operations in the framework. The database manager 121 stores in the storage 123 service lists of other devices found by the service discovery protocol component 127 and a service description thereof. The service list is retrieved from the storage 123 upon request of the service API. The stored service list is continuously managed. The service list manager 117 manages a service list to support concurrent services for the framework. The task manager 125 manages a task queue for pending service requests. The log manager 115 is a component for a developer, and records the entire operations executed in the service consumer.

The service discovery protocol component 127 collects service lists by sending a service discovery request over the network to peripheral devices and receiving a service discovery response from them. The collected result is transmitted to the database manager 121. The service transmission / reception protocol component 129 sends a service request to a corresponding device in the vicinity according to a request from the service API through the service manager 113 and receives a service reply from the device.

3, the service provider side structure of the framework system according to the present embodiment will be described in detail. As shown, the service provider side includes a message parser 211 and a service manager 213 as components of an interface layer, a log manager 215 and a service database manager as components of a core layer. database manager (217), service provider controller (221), scheduler (scheduler, 225), service discovery protocol component (service discovery protocol component 227) and service transmission and reception protocol component (service transfer) as a component of the communication layer / receiver protocol component 229 is provided.

The service manager 213 requests a service from the service API and notifies the message parser 211 and the service provider controller 221 of the result. In particular, the service manager 213 requests a service from a service API according to a service request of another device introduced through the service transmission / reception protocol component 229. The message parser 211 parses the input API parameters and converts them into an understandable format for the framework.

The service provider controller 221 controls all the components and operations in the framework. The service database manager 217 stores a list of services supported by the service provider in the service DB 219. Scheduler 225 schedules the service transmit and receive protocol component 229 to send a service response when some event occurs or is activated in a periodic cycle. Service data for the service response is temporarily stored in the register 223.

The service discovery protocol component 227 receives the service discovery request from the service consumer and forwards it to the upper layer. The service provider controller 221 then determines whether to send a service list. The service discovery protocol component 227 receives a service list stored in the service DB 219 from the service database manager 217 and transmits a service discovery response including the service list to the service consumer.

The service transmit / receive protocol component 229 receives a service request from the service consumer, receives the service response from the service provider controller 221, and transmits the service response to the service consumer. At this time, the transmission time is determined by the scheduler 225.

4 is a flowchart illustrating a process of collecting a service list in the above-described framework system according to an embodiment of the present invention.

When service list manager 117 initiates service discovery, service discovery protocol component 127 generates a service discovery request. The service discovery request is transmitted to surrounding devices by broadcasting. Receiving the service discovery request, the service provider checks whether a service discovery response is possible. The service database manager 217 then generates a service discovery reply containing the service list, and the service discovery protocol component 227 sends it in a unicast fashion to the service consumer that made the service discovery request. As shown, other service providers that have received the service discovery request likewise generate and send a service discovery response to the service consumer. The service consumer receives a service discovery response from each service provider and stores a list of services included in the storage 123.

5 is a flowchart illustrating a process in which a service consumer requests a service and a service provider responds to the framework system according to an embodiment of the present invention.

The service manager 113 of the service consumer requests necessary service data according to the request of the service API. The database manager 121 then retrieves from the repository 123 a service provider suitable for the service data and its service list. The service transmission / reception protocol 129 generates a service request according to the searched result and transmits it to the corresponding service provider in a unicast manner. The service transmission / reception protocol component 229 of the service provider that receives the service request forwards it to the service manager 213. Delivery of the service request may be scheduled by the scheduler 225 as shown.

The service manager 213 generates service data through a service API according to the service request. The service data is either passed directly to the service transmit / receive protocol component 229 or temporarily stored in the register 223 and then delivered to the service transmit / receive protocol component 229 in accordance with the scheduling by the scheduler 225. The service transmit / receive protocol component 229 then generates a service response containing the service data and sends it to the service consumer in a unicast manner. The service transmission / reception protocol 129 receives a service response and transmits service data included therein to the service manager 113. The service manager 113 delivers the service data to the service application that needs it.

The present invention described above can be applied to, for example, the following cases. A device that has a camera device that needs it, but can't run it because it doesn't have a camera device, can run that application in collaboration with a device that can provide camera functionality around it. For example, a device having a two-dimensional image code reader but no camera (a service consumer) and a device service provider having a camera apparatus can read the image code using the above-described present invention. Alternatively, if a cooperation between the device (service consumer) and the device (service provider) that has an RFID reader is downloaded but has an application that requires RFID but is not available, the service consumer reads the RFID value read from the service provider. You can run the application using.

Meanwhile, the above-described embodiments of the present invention can be written as a program that can be executed in a computer, and can be implemented in a general-purpose digital computer that operates the program using a computer-readable recording medium. The computer-readable recording medium may be a magnetic storage medium (for example, a ROM, a floppy disk, a hard disk, etc.), an optical reading medium (for example, a CD-ROM, DVD, etc.) and a carrier wave (for example, the Internet). Storage medium).

So far I looked at the center of the preferred embodiment for the present invention. Those skilled in the art will appreciate that the present invention can be implemented in a modified form without departing from the essential features of the present invention. Therefore, the disclosed embodiments should be considered in descriptive sense only and not for purposes of limitation.
