detailed description

In order to make the purpose, technical solution and advantages of the application clearer, the embodiments of the application will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

Embodiment one

Figure 1 is a schematic diagram of a data storage and forwarding system provided by this embodiment, including a storage device and a server. The storage device can be a mobile phone, a PAD, a camera, a computer, etc. equipment.

In this embodiment, the storage device is divided into an initiator storage device and a responder storage device. In an example, the initiator storage device has a built-in 2G module and one or more short-range wireless communication modules, and the responder storage device has a built-in 3G/4G module and one or more short-range wireless communication modules. The initiator storage device and the responder storage device may communicate through a short-range wireless communication module. The short-range wireless communication may use Bluetooth, infrared data transmission (IrDA), ultra-wideband (UWB: Ultra Wideband), WiFi or other short-range wireless communication technologies. The initiator storage device can communicate with the server through the 2G module, and the responder storage device can communicate with the server through 3G/4G or wired technology.

The responder storage device sets a certain amount of free storage space and registers the free storage space on the server as a shared space. The communication sends the data to the responder storage device, and then the responder storage device stores and forwards the data to the server.

It is inconvenient for the initiator’s storage device to directly transmit data to the server. For example, the initiator’s storage device can only transmit data to the server through the 2G network, but there is not enough transmission time under low-speed conditions; or, although the initiator can transmit data through WiFi Data transmission to the server, but at an additional cost (transmission between end devices in the LAN is free), etc.

As shown in FIG. 2, this embodiment provides a data storage and forwarding control method, including:

Step 110: The server receives the data storage and forwarding request sent by the initiator storage device, and acquires the initiator user ID and the location information of the initiator storage device;

When the initiator user needs to send data to the server in a forwarding manner, a data storage and forwarding request is sent to the server through the initiator storage device.

The server may require the initiator user to register before using the service, and assign an initiator user ID to the initiator user during registration. The server uses the initiator user ID to identify the initiator user's storage space on the server,

Preferably, the data storage and forwarding request also carries information about the size of the data to be forwarded.

Step 120: The server determines a responder storage device that can forward data to the initiator storage device;

This step can be further divided into the following steps:

In the first step, the server searches for the shared capacity and location information reported by the registered responder storage device according to the location of the initiator storage device and the size of the data to be forwarded;

The server may query the location of the initiator storage device from the network where the initiator storage device is located, or the initiator storage device may report its location information in the data storage and forwarding request.

In this embodiment, the server registers the responder storage device, and saves the shared capacity and location information for data storage and forwarding reported by the registered responder storage device. The responder storage device may share part of the storage space according to its own resource conditions to store data sent by other storage devices to be forwarded to the server. Shared capacity and location information can be reported when the initiator storage device is registered, or can be reported after registration and updated in time, such as reporting location information to the server regularly or when the location is updated, so that the server can update the location information in time . The server may also actively query the location information of the registered responder storage device.

The location information of the initiator storage device and the responder storage device can be expressed by the area defined by the network where the storage device is located, such as a cell, tracking area, etc. in the mobile communication network, or by the position coordinates obtained by the GPS positioning device in the storage device. wait.

In the second step, the server takes the responder storage device that is located in the same area as the initiator storage device or whose distance is smaller than a set distance threshold, and whose shared capacity is not less than the data size, as the determined responder storage device.

The location information of the sender's storage device and the receiver's storage device can be area information defined in the network, such as cell information in a mobile communication network. When the responder's storage device and the initiator's storage device are located in the same area, the server believes that the two may establish The short-range wireless communication connection, so the responder storage device in the same area can be determined as the responder storage device that can forward data to the initiator storage device. At this time, all determined responder storage devices may be returned to the initiator storage device.

The location information of the sender's storage device and the receiver's storage device can also be the location coordinates obtained by GPS positioning, and the server can determine that the responder's storage device whose distance from the initiator's storage device is less than a set distance threshold value can be the initiator's storage device. The responder storage device to which the storage device forwards data. At this time, one or more responder storage devices that are closest to the initiator storage device among the determined responder storage devices may be returned to the initiator storage device.

It should be noted that the above-mentioned "can forward data for the initiator storage device" is a confirmation of the server, and does not mean that the subsequently determined responder storage device must be able to forward data for the initiator storage device.

In other embodiments, the data to be forwarded may also be sent to the responder storage device in batches. When the server selects the responder storage device for the initiator user, it can select the responder storage device with a shared capacity smaller than the size of the data to be forwarded according to the preset selection rules. For example, if the data to be forwarded is allowed to be sent to the responder in two Party storage device, the shared capacity of the responder storage device only needs to be no less than 1/2 of the size of the data to be forwarded.

Step 130: The server returns all or part of the determined NFC connection information of the responder storage device to the initiator storage device;

This step in turn includes:

Step 1: Send a data forwarding query to all or part of the determined responder storage devices;

The server sends a data forwarding query to all or part of the responder storage devices determined in step S102. The responder user chooses whether to accept the data forwarding request. If the user agrees to the data forwarding instruction, the responder storage device returns a data forwarding confirmation to the server, carrying the short-range wireless communication connection information of the responder storage device. The short-range wireless communication connection information is information required by the initiator storage device to establish a short-range wireless communication connection with the responder storage device, for example, may include the identifier of the responder storage device and the connection password of the responder storage device.

The short-range wireless communication function of the responder storage device may be turned off when idle, and the short-range wireless communication function may be automatically activated when data forwarding is agreed.

Step 2: Return all or part of the short-distance wireless communication connection information of the responder storage device that returns the data forwarding confirmation to the initiator storage device.

The server can send all received short-range wireless communication connection information of the responder storage device to the initiator storage device, and can also select some responder storage devices and send the short-range wireless communication connection information of this part of the responder storage device Give the initiator storage device.

Step 140: The initiator storage device establishes a wireless connection with the responder storage device according to the short-range wireless communication connection information, and sends the data to be forwarded, the address information of the server, and the initiator user ID to the responder storage device;

The initiator user may select a responder storage device from the received responder storage devices, and establish a short-range wireless communication connection with the responder storage device according to the short-range wireless communication connection information of the responder storage device. If the connection cannot be established, try to establish a NFC connection with the next responder storage device.

Before the initiator storage device sends forwarded data, it can use WPA2 and other encryption technologies to pass encryption to enhance data security. The encryption password can be set by the initiator user when registering in the server, or can be set in other ways, and the encryption password can also be bound with the initiator user ID. After encryption, the responding user cannot identify the data it forwards. When the initiator user accesses the data forwarded by himself, he needs to decrypt it through the key before restoring the original data to be forwarded.

Step 150: The responder storage device receives the data to be forwarded sent by the initiator storage device, the address information of the server, and the user ID of the initiator, stores the data to be forwarded in a shared space, and then sends the forwarded data and the initiator the user identification is sent to said server;

The responder storage device may simultaneously accept data forwarding from multiple initiator storage devices, and the servers to be forwarded may also be different. After receiving the data to be forwarded, the responder storage device may forward the data to be forwarded to the server immediately, or may forward the data to the server during an idle period.

Step 160: The server receives the data forwarded by the responder storage device and the initiator user ID, stores the forwarded data in the space corresponding to the initiator user ID, and returns a data forwarding completion confirmation to the corresponding initiator storage device.

The server can also record the log information of this data forwarding and storage.

According to the above steps, the initiator storage device can forward the data to the server through the responder storage device. In other embodiments, the responder storage device may also report the sharing period, and enable the data storage and forwarding function for the shared space only within the sharing period. When the server provides the storage device of the responder to the storage device of the initiator, it may carry sharing period information for the user of the initiator to choose. The responder storage device may also submit a change application to the server to change the shared capacity or shared period information.

In addition, payment mechanisms can also be set. Before the initiator storage device sends forwarded data to the responder storage device, the initiator user needs to prepay the space occupation fee to the responder user. The prepaid space occupation fee will be kept by the server, and will be transferred by the server to the responder after the data forwarding is completed. Responder users to ensure the reliability of fee payment. The payment standard and payment rule of the space occupation fee may be provided by the server or the responding user. If a payment mechanism is set, the initiator storage device also needs to provide the server with the payment account of the initiator user when sending the forwarding data to the server.

It should be noted that the storage device at the initiator and the storage device at the responder may be configured with a data store and forward function switch. When the initiator storage device disables the data store and forward function, the initiator storage device will no longer be able to rely on the data store and forward system to indirectly transmit data to the server; when the responder storage disk disables the data store and forward function, the responder storage device Data storage and forwarding services will no longer be provided for other storage devices. The server can display whether the data store and forward function of the responder storage device is turned off. When the server selects a responder storage device that can forward data for the initiator storage device, it will not do anything to the responder storage device that disables the data store and forward service. consideration, and will not send a data forwarding query to the responder storage device.

In addition, the responder storage device can be in a dormant or standby state when it is idle. When the power-saving power switch monitoring device receives the data forwarding query sent by the server, it will turn on the power, so that the responder storage device is in a working state, and according to the current The status of the storage device confirms whether it needs to accept the data forwarding request.
