detailed description

It is understood that the specific embodiments described herein are merely illustrative of the disclosure and are not intended to limit the disclosure.

The present disclosure provides a data transmission method. Referring to FIG. 1, in a first embodiment of the data transmission method of the present disclosure, the data transmission method includes:

Step S10: When the IP data is received by the IP node, extract the node identifier of the destination node carried by the service data.

As is well known to those skilled in the art, an Ad Hoc network is a multi-hop, centerless, self-organizing wireless network, also known as a multi-hop network, an infrastructure-free network, or a self-organizing network. The entire network has no fixed infrastructure, each Ad Hoc Festival Points are mobile and can dynamically maintain contact with other Ad Hoc nodes in any way. In the Ad Hoc network, due to the limited wireless coverage of the Ad Hoc node, two Ad Hoc nodes that cannot communicate directly can be forwarded by other nodes. Each Ad Hoc node is also a router that performs discovery and maintains the routing to other Ad Hoc nodes.

Based on the existing Ad Hoc technology, the data transmission method proposed in this embodiment is applied to the Ad Hoc converged communication system shown in FIG. 2, and is used for implementing CC data transmission, which is specifically performed by the data transmission apparatus. As shown in FIG. 2, in the Ad Hoc converged communication system to which the present disclosure is applied, an IP node and an Ad Hoc node are included, wherein the IP node accesses both the Ad Hoc network and the IP network. In a specific implementation, the IP node may be operated by a PC (Personal Computer, a personal computer, or a personal computer), and accesses the IP network through a wired manner, and accesses the Ad Hoc network through the set Wi-Fi module; the Ad Hoc node includes Mobile terminals such as mobile phones, notebook computers, digital broadcast receivers, PDAs (Personal Digital Assistants), PADs (tablets), game consoles, and PMPs (portable multimedia players).

In this embodiment, the data transmission device detects the service data received by the IP node, and when the IP node receives the service data, parses the received service data, and extracts the node identifier of the destination node carried by the service data. . The node identifier is used to uniquely identify an Ad Hoc node in the Ad Hoc network.

After extracting the node identifier of the destination node carried by the received service data, the data transmission device compares the extracted node identifier of the target node with the node identifier of the IP node where it is located to determine whether the IP node is the received service. The destination node of the data.

When the node identifier of the destination node is different from the node identifier of the IP node, the IP node is not the destination node of the received service data, and the data transmission device obtains the association information of the node identifier and the connection information stored by the IP node. The connection information to the destination node is then forwarded to the destination node based on the Ad Hoc network based on the connection information of the destination node.

Step S20: When the node identifier of the destination node is the same as the node identifier of the IP node, obtain the connection information of the stored Ad Hoc node associated with the IP node.

When the node identifier of the destination node is the same as the node identifier of the IP node, the IP node is the destination node of the received service data, and the data transmission device identifies whether the IP node has an associated Ad Hoc node, and if so, obtains the stored Connection information of the Ad Hoc node associated with the IP node. It should be noted that when an IP node has an associated Ad Hoc node, the node identifier of the IP node is the same as the node identifier of the associated Ad Hoc node, and the data transmission device is specifically based on the association information of the node identifier and the connection information stored by the IP node. Obtaining the connection information associated with the node identifier of the IP node; since the node identifier of the IP node is the same as the node identifier of the associated Ad Hoc node, the node identifier of the IP node is associated with the connection information of the IP node and its associated Ad Hoc Connection information of the node, after acquiring the connection information associated with the node identifier of the IP node, the data transmission device uses the connection information other than the connection information of the IP node in the acquired connection information as the Ad Hoc node associated with the IP node. Connection information.

Step S30: Transmit the service data to the associated Ad Hoc node based on the Ad Hoc network according to the connection information.

After obtaining the connection information of the Ad Hoc node associated with the IP node, according to the connection information of the associated Ad Hoc node, the service data received by the IP node is transmitted to the Ad Hoc node associated with the IP node based on the Ad Hoc network. CC copy of current business data. The connection information includes at least an IP address and a receiving port number of the receiving end, and may also include a MAC address of the receiving end.

It is easy to understand that in order to realize the CC data copy between the IP node and the associated Ad Hoc node, the IP node needs to be associated with the Ad Hoc node that needs to copy the service data. The following IP node is the PC, Ad Hoc. The node is a mobile phone, and the associated operation of the IP node and the Ad Hoc node is described.

On the Ad Hoc node, the user selects the original identifier for calculating the node identifier based on the association interface provided by the mobile phone. Optionally, in this embodiment, the mobile phone number of the mobile phone or the MAC address of the mobile phone is used as the original identifier selected by the user. After receiving the user's selection information, the mobile phone uses a hash algorithm such as MD5 to calculate a hash value of the original identifier corresponding to the selection information, and uses the calculated hash value as its node identifier. For example, if the user selects the mobile phone number of the mobile phone as the original identifier of the computing node identifier, the mobile phone extracts the mobile phone number carried by the SIM card, and uses the MD5 algorithm to calculate and extract the hash value of the mobile phone number as its node identifier.

On the IP node side, the user inputs the original identifier for calculating the node identifier based on the association interface provided by the PC (here, the same original identifier as that selected in the mobile phone needs to be input). After receiving the original identifier input by the user for calculating the node identifier, the PC calculates the hash value of the input original identifier by using the same hash algorithm of the mobile phone, and uses the calculated hash value as its node identifier. For example, the user selects the mobile phone number of the mobile phone as the original identifier of the mobile phone computing node identifier in the mobile phone. To realize the association between the mobile phone and the PC, the user needs to input the mobile phone number of the mobile phone as the PC to calculate the original identifier of the node identifier, correspondingly, After receiving the mobile phone number of the mobile phone input by the user, the PC uses the hash value of the mobile phone number input by the MD5 algorithm, and uses the calculated hash value as its node identifier.

Based on the foregoing description, it can be understood that after the IP node calculates its node identifier, the association between the Ad Hoc node and the IP node is completed. At this time, the same node identifier (after the association between the Ad Hoc node and the IP node is completed, the associated Ad Hoc node and the node identifier of the IP node are the same) are associated with the transmission information of the Ad Hoc node.

Optionally, an association identifier that is initially 0 may also be set on the IP node, and after the association between the Ad Hoc node and the IP node is completed, the association identifier is set to 1.

It should be noted that the function implementation of the above IP node is completed based on the data transmission device of the setting.

In the data transmission method provided in this embodiment, when the IP data of the IP network and the Ad Hoc network are simultaneously accessed, the received Ad Hoc network transmits the received service data to its associated Ad Hoc node when receiving the service data. The CC data of the service data is realized, thereby avoiding the consumption of traffic of the Ad Hoc node. Correspondingly, when the Ad Hoc node is a mobile terminal, the IP node can be used to copy the instant communication data, thereby reducing the cost of realizing the instant messaging function of the mobile terminal.

Further, based on the first embodiment, a second embodiment of the data transmission method of the present disclosure is proposed. In the embodiment, before the step S10, the method further includes:

When the node identifier of the source node is different from the node identifier of the IP node, the process proceeds to step S10.

In this embodiment, the transmitted service data carries the active node in addition to the node identifier of the destination node. The node identifier is used to determine whether the received service data is loopback service data, where the source node is the sender that initially sends the service data.

Correspondingly, when detecting that the IP node receives the service data, the data transmission device first parses the received service data, extracts the node identifier of the source node carried by the service data, and extracts the carried the received service data. After the node identifier of the source node, the data transmission device compares the node identifier of the source node with the node identifier of the IP node where the data node is located to determine whether the service data is loopback service data.

When the node identifier of the source node is different from the node identifier of the IP node, the received service data is non-loopback service data, that is, the service data sent by other nodes, and the data transmission device extracts the purpose of the received service data. The node identifier of the node is used to start the process of copying the foregoing service data. For details, refer to the related description of the foregoing first embodiment, and details are not described herein again.

Further, in this embodiment, after the step of extracting the node identifier of the source node carried by the service data when the IP data is received by the IP node, the method further includes:

When the node identifier of the source node is the same as the node identifier of the IP node, the received service data is loopback service data, that is, the service data is initially sent by the IP node, and finally sent back to the IP node. The transmission device directly discards the received service data and does not process it.

Further, based on the foregoing first or second embodiment, a third embodiment of the data transmission method of the present disclosure is proposed. In this embodiment, after step S30, the method further includes:

It should be noted that, in this embodiment, the operation of re-associating the Ad Hoc node with the IP node is further added on the basis of the foregoing embodiment. The following is only for the difference, and other reference may be made to the foregoing embodiment, and details are not described herein again. .

In this embodiment, when the user does not need the IP node to copy the service data, the association between the IP node and the Ad Hoc node can be cancelled. The following uses the Ad Hoc node as the mobile phone, and the IP node is the PC to explain the association between the Ad Hoc node and the IP node.

On the IP node side, after detecting the mobile phone (that is, the mobile phone associated with the PC) whose same identity as the node is connected to the Ad Hoc network, the PC sends a prompt message to the detected mobile phone.

On the Ad Hoc end, after receiving the prompt information transmitted by the PC, the mobile phone displays the received prompt information for the user to confirm whether to open the CC copy function of the PC; when receiving the information of the "open CC function" input by the user The mobile phone can maintain its current relationship with the PC without processing it; when receiving the information of the "closed CC function" input by the user, the mobile phone sends an undo CC command to the PC.

On the IP node side, when the PC receives the revocation CC command sent by the mobile phone, the PC recalculates its node identifier. The PC uses its MAC address as the original identifier of the compute node identifier, and uses the MD5 algorithm to calculate the hash value of its MAC address, and uses the calculated hash value as its node identifier. At the same time, the association relationship between the connection information and the node identifier of the mobile phone is deleted, and the association identifier is set to 0 to complete the cancellation of the association relationship. Optionally, the PC may also send a prompt message that the “association relationship has been released” to the mobile phone, and the mobile phone performs the display.
