Description

Method and system for continuing wireless communication without interruption

The present invention generally relates to a method and system for maintaining a smooth connection and avoiding interruption when capturing a wireless network connection, and more specifically for integrating and adjusting various factors affecting network connection quality, providing wireless Communication transmission continues the method of uninterrupted service and its system.

When deploying a wireless communication node in a large area, the network coverage must be considered, that is, the ratio of the wireless signal range to the floor area of the field. In addition, the wireless signal coverage areas of each wireless communication node often overlap, but some areas may not be covered by signals. When the user moves in the field, it may move to a location that is not covered by the current wireless communication node signal, which may cause the network to be disconnected.

If the mobile enters a signal overlap of more than two nodes, the user must select one of the nodes to access the network. Since the node is generally selected according to the signal strength, the stronger signal node may be more congested at this time, but the weaker signal can provide a relatively larger bandwidth.

In order to solve the quality problem of such network capture applications, the Republic of China Patent No. 4812871 discloses that the wireless network connection principle is automatically adjusted according to the user activity level. However, this prior art still only relies on the strength of the wireless network signal between the user device and the wireless communication node as a benchmark, and has not taught how to solve the network congestion problem.

US Patent No. 8,005,457 (Method and system for verifying network resource usage records) discloses that user equipment uses a wireless communication node to connect to the Internet. The billing mechanism of the road, and how to interrupt the connection of malicious users. Although it is mentioned that AAA System can be used to authenticate users and calculate network usage, it does not reveal how to control wireless communication nodes in order to improve the overall network QoS.

The quality of experience enhancement for wireless networks based on received signal strength at a mobile device discloses that the user equipment selects which wireless communication node should be connected according to the received signal strength indicator (RSSI). . This patent discloses that the user device can actively decide how to switch between two nodes, wherein the connection details and selection mechanism between the user device and the node are described in detail. However, this prior art fails to suggest a mechanism by which a wireless communication node determines which user equipment can be connected.

U.S. Patent No. 8,817,657 (Techniques for Enhanced Network Discovery) discloses that multicomm wireless devices can use scanning to obtain a list of respective base stations of a heterogeneous network, merge them, and merge the lists. Provided to other devices. Although this prior art utilizes pre-organizing and storing a list of wireless communication nodes for uninterrupted communication, there is still a lack of a central connection management mechanism to optimize the overall routing service.

The present invention proposes a method for integrating various factors affecting the quality of the network connection, such as a network topology and a quality of service (QoS), to provide an uninterrupted service for wireless communication transmission.

The method of the present invention avoids the existing signal strength indicator (RSSI) between the user equipment and the wireless communication node to determine the wireless communication section. The point provides services, and some wireless communication nodes are too connected, resulting in poor overall network usage.

The method of the invention can also avoid the problem that the user can connect to the wireless communication node, but the reliability of the network use and the transmission rate are low due to the external bandwidth congestion of the wireless communication node.

To achieve the above and other objects, the present invention provides a method for continuing uninterrupted wireless communication, which can be used by a network capture service system to capture a network by a user device through at least one wireless communication node of the system. The central computing unit of the service system includes: the mobile device, the connection status of the user equipment and the at least one wireless communication node, the previous connection record, and the instantaneous load of the at least one wireless communication node. Situation, for integration optimization calculations. According to the optimization calculation result, it is determined whether the user equipment should be disconnected by the at least one wireless communication node to which it is currently connected, and separately connected to another wireless communication node. If the determination is no, the user equipment maintains a connection with the at least one wireless communication node currently connected. If the determination is yes, the central operation unit transmits the connection information of the user equipment to the other wireless communication node, and assists in transmitting the network optimization information of the other wireless communication node to the user equipment. The currently connected at least one wireless communication node then disconnects the user equipment; and the user equipment utilizes the network optimization information of the other wireless communication node that has been obtained to quickly connect to the other wireless The communication node establishes a connection, reduces the round-trip time of switching between wireless communication nodes to continue the uninterrupted connection of the connection, thereby ensuring the quality of service of the network.

The present invention further provides a system for continuing wireless communication without interruption, which can be used by a network capture service system to capture a network through a wireless communication node of at least one wireless communication node of the system. The system includes at least one wireless communication node and a central operational unit. The central computing unit performs optimal integration according to the mobile device, the connection status of the user equipment and the at least one wireless communication node, the previous connection record, and the instantaneous load status of the at least one wireless communication node. The calculation is performed to determine whether the user equipment should be disconnected by the at least one wireless communication node to which it is currently connected, and separately connected to another wireless communication node. When the determination is no, the user equipment maintains a connection with the at least one wireless communication node currently connected. When the determination is yes, the central operation unit transmits the connection information of the user equipment to the other wireless communication node, and assists in transmitting the network optimization information of the other wireless communication node to the user equipment. Then, the currently connected at least one wireless communication node cuts off the connection with the user equipment; and the user equipment utilizes the network optimization information of the other wireless communication node that has been obtained, and quickly connects to the other The wireless communication node establishes a connection, which greatly reduces the round-trip time of switching between wireless communication nodes to continue the uninterrupted connection of the connection, thereby ensuring the quality of service of the network.

In the method for continuing the wireless communication of the present invention, the method further includes evaluating the service quality when the user equipment is connected to the wireless communication node, and can be used as a basis for the central operation unit to switch the network node. The evaluation includes: determining whether a relative signal strength indicator RSSI (Received Signal Strength Indicator) between the user equipment and the wireless communication node is greater than a certain value; if not, the central operation unit connects the user equipment The information is transmitted to the other wireless communication node and assists in transmitting network optimization information of the other wireless communication node to the user equipment.

In the method for continuing the wireless communication of the present invention, the relative wireless signal strength indicator is a measure of the signal strength between the wireless communication node and the user equipment.

In the method for continuing the wireless communication of the present invention, the quality of service level of the wireless communication node depends on the ratio of the bandwidth that can be currently served and the maximum service bandwidth, and the set of several parameters, and the parameters. Contains network packet loss rate and time to and from the wireless communication node and user equipment.

In the method and system for uninterrupted wireless communication of the present invention, the integrated optimization calculation performed by the central operation unit further includes predicting the location of the user equipment at a certain time point, and the prediction includes determining the user equipment.

2 is a flow chart showing the flow of authenticating a user device by a wireless communication node or a central computing unit in accordance with an embodiment of the present invention. In FIG. 2, the central processing unit authenticates and identifies the user equipment to control the user equipment approved by the management system to capture the network through the wireless communication node in the system. The process begins with step 100. First, in step 102, when a user equipment attempts to perform network capture, the wireless communication node within its signal range is conveniently scanned and used by its wireless communication capability (eg, IMEI, MAC ID, MAC address, BT MAC). The identification code of the device.

Thereafter, the wireless communication node facilitates searching for the user identification code stored in the local terminal in step 104 to identify in step 106 whether the user device is a legitimate user authenticated by the system. If the result of the check is affirmative, the wireless communication node of the system facilitates the user device to be connected in step 108 to connect the user device to the network.

Conversely, if the near-ground wireless communication node of the user equipment performs the identification result of the stored information and determines that the user equipment is not a certified legitimate user, the system proceeds to step 120. The master data file of the inspection system is retrieved by the central operation unit, and in step 122, it is determined whether the user equipment is a legitimate user authenticated by the system. If the result of the check is affirmative, the process returns to step 108, and the wireless communication node allows the user device to connect to the network.

However, if the result of the determination in step 122 is still negative, the system facilitates the registration of the user equipment in step 124. This can be done by the user equipment through its connected near-Earth wireless communication node. Once the login registration is successful, the system facilitates the establishment of its identification code for the newly registered user device in step 126. Then, in step 128, the identification data of the new user equipment and other related data are forwarded to all wireless communication nodes in the system for near-ground storage. Thereafter, the process returns to step 102 to re-execute the scanning (step 102), data search (step 104), identification of the comparison (step 106), and the like for the new user device. At this time, since the new user equipment is already a legitimate user of the system, it can of course be successfully connected to the network in step 108.

The method of the present invention described above in FIG. 2 is a method for continuing wireless communication without interruption. A network capture service system can be used for a user device to retrieve a network through a plurality of wireless communication nodes of the system. The method includes a central operation unit of the system according to the movement of the user equipment, a connection signal state of the user equipment and the at least one wireless communication node, a previous connection record, and an immediate load condition of the at least one wireless communication node. , for integration optimization calculations. The method further comprises determining, according to the optimization calculation result, whether the user equipment should be disconnected by the wireless communication node to which it is currently connected, and separately connected to another wireless communication node. If the determination is no, the user equipment maintains a connection with the currently connected at least one wireless communication node. If If the determination is yes, the central computing unit transmits the connection information of the user equipment to the other wireless communication node, and assists in transmitting the network optimization information of the other wireless communication node to the user equipment. Thereafter, the currently connected at least one wireless communication node disconnects the user equipment, and the user equipment utilizes the network optimization information of the other wireless communication node that has been obtained, and quickly connects to the other The wireless communication node establishes a connection, reduces the round-trip time of switching between wireless communication nodes to continue the uninterrupted connection of the connection, thereby ensuring the quality of service of the network.

In an embodiment of the present invention, the integrated optimization calculation performed by the central operation unit further includes predicting a location of the user equipment at a certain time point, and the prediction method includes determining a moving direction and a speed of the user equipment. The other wireless communication node to be switched by the user equipment may be located at a location predicted by the central operating unit of the user equipment. The service bandwidth of the at least one wireless communication node currently connected to the user equipment may be higher than the service bandwidth of the other wireless communication node. The user device can be a device with computing and wireless networking capabilities, including a smart phone, tablet, laptop, drone or driverless car.

In an embodiment of the invention, the method further comprises evaluating the quality of service of the user equipment when connected to the wireless communication node for use as a basis for the central computing unit to switch network nodes. The evaluation includes determining whether the relative radio signal strength indicator RSSI (Received Signal Strength Indicator) between the user equipment and the wireless communication node is greater than a certain value. If not, the central computing unit transmits the connection information of the user equipment to another wireless communication node, and assists in transmitting the network optimization information of the other wireless communication node to the user equipment. The relative wireless signal strength indicator is a measure of the signal strength between the wireless communication node and the user equipment. Moreover, the quality of service level of the wireless communication node depends on the bandwidth and maximum service that it can still serve. The ratio of the bandwidth to the bandwidth, and a set of parameters, including the network packet loss rate and the time of the signal to and from the wireless communication node and the user equipment.

The method of the present invention described above can be implemented in a system in which wireless communication continues uninterrupted, the system comprising a plurality of wireless communication nodes and a central operating unit. The central computing unit may perform integration optimization calculation according to the movement condition of the user equipment, the connection signal state of the user equipment and the at least one wireless communication node, the previous connection record, and the instantaneous load condition of the at least one wireless communication node. In order to determine whether the user equipment should be disconnected by the at least one wireless communication node to which it is currently connected, and separately connected to another wireless communication node. When the determination is no, the user equipment maintains a connection with the currently connected wireless communication node. When the determination is yes, the central computing unit transmits the connection information of the user equipment to the other wireless communication node, and assists in transmitting the network optimization information of the other wireless communication node to the user equipment. At this time, the currently connected wireless communication node cuts off the connection with the user equipment, and the user equipment quickly establishes the network optimization information of the other wireless communication node that has been obtained, and quickly establishes with the other wireless communication node. The connection greatly reduces the round-trip time of switching between wireless communication nodes to continue the uninterrupted connection of the connection, thus ensuring the quality of service that is captured by the network.

The method and system of the present invention described above is characterized in that: the two-layer authentication of the wireless communication node and the central computing unit enables the wireless communication node to return to the central computing unit to authenticate the user equipment every time to reach the user equipment. The requirement of fast connection can also be determined by the central operator's authentication and control to determine whether the user equipment can obtain the connection capability of the network. The central computing unit can also adjust the communication bandwidth of multiple wireless communication nodes to achieve global optimization by controlling the connection of user equipment.

3 is a state diagram showing a decision process in which the central computing unit 200 determines which wireless communication node is connected to the user equipment and requires the user equipment to reconnect to another particular wireless communication node, in accordance with an embodiment of the present invention.

If the user device 220 is desired to change from the A wireless communication node 212 to the B wireless communication node 214, the central operating unit 200 sends two indicators. The indicator 241 indicating that the disconnection is required requires the A wireless communication node 212 to disconnect from the user equipment 220, and the B-wireless communication node 214 is notified by the indicator 242 allowing the connection to accept the user equipment 220. Connected.

After the A wireless communication node 212 receives the indicator 241, the indicator 243 for sending the disconnect connection interrupts the connection with the user equipment 220 and knows that it will be served by the B wireless communication node 214. At this time, the user equipment 220 scans the available network signal, and sends a request to connect with the indicator 244 to successfully connect to the B wireless communication node 214.

According to the present invention, the network connection status when the user equipment is connected to each wireless communication node is completely recorded in each wireless communication node, so as to optimize the overall connection service of the system. The time-history diagram of Figure 4 shows the detailed process of a user equipment switching network connections within the system of the present invention in accordance with the embodiment depicted in Figure 3.

When the central processing unit 200 of the system confirms that the user equipment 220 should disconnect its connection with the A wireless communication node 212 and separately connects to the B wireless communication node 214, the central operation unit 200 prioritizes the user equipment 220. The indicator 313 is passed to the B wireless communication node 214 and assists in transmitting the network optimization information 315 of the B wireless communication node 214 to the user device 220.

Next, the A wireless communication node 212 disconnects from the user equipment 220. Since the user equipment 220 has obtained the network optimization information 315 of the B wireless communication node 214, the connection with the B wireless communication node 214 can be quickly established.

The context described above is system integrated management via a dedicated central computing unit 200 for overall optimization of system operation. In a general hardware resource of the connection service system, a user equipment 220 is deliberately disconnected from an available A wireless communication node 212 and connected to another B wireless communication node 214 to balance resources. The method of using, thereby enabling each user device to obtain the best connection service quality, is a feature of the present invention. This can greatly reduce the round-trip time (RTT) of switching between wireless communication nodes and improve QoS.

For example, in the foregoing examples, for the same user equipment (e.g., 220), it is assumed that there are more than two wireless communication nodes 212, 214 that can provide connection services at the same time within the range of their access distances. Even if an A wireless communication node 212 has been connected, the management calculation result of the central operation unit 200 of the system may require that the current A wireless communication node 212 should be interrupted, and otherwise connected to another B wireless communication node 214, even if This other B wireless communication node 214 may be a node of a smaller bandwidth. This may be because the system has determined that there are fewer users currently served by the node, so the user 220 can use a larger bandwidth, so for the user 220, the B wireless communication node 214 can provide better service quality.

Furthermore, the central processing unit 200 of the system may continuously determine the operation status of the overall system, and may also determine in advance that the user is about to leave the original A wireless communication node 212 and move toward the other B wireless communication node 214. . These predictive nature of system management disposal can further promote the overall service quality of the system. Figure 5 below illustrates this approach.

Figure 5 illustrates a multi-node signal coverage environment, such as the one depicted in Figures 2 and 3 above, where the central computing unit predicts the location of the user device at a certain point in time and specifies the appropriate wireless communication node for the user device. Connected.

In accordance with the present invention, the central computing unit is capable of verifying and identifying the identification code of the user device. When the same user equipment appears in the system, the central operation unit can predict the location where the user equipment may appear at a certain point in time via techniques such as the mobile mode of the user equipment and the network topology. Based on this prediction, the central operating unit can specify the appropriate wireless communication node in the system to provide connection services for the user equipment. Figure 5 is used to illustrate this process.

The circles 412, 414 and 416 indicated by the dashed lines in Fig. 5 indicate the wireless signal coverage of the wireless communication nodes 512, 514 and 516, respectively. When the user equipment 220 appears in the system service scope of FIG. 5, the central operation unit can authenticate the wireless communication node 512 and the wireless communication node 514 according to the system operation information controlled by the central operation unit, and the user equipment 220 can be connected. The user equipment 220 is predicted to move the path from 520a to 520b and then to 520c.

However, the actual movement of the user device 220 does move from 520a to 520b, but not to 520c, but to 520b1. However, in accordance with the present invention, when the user device 220 appears in the 520a location, it will receive signal optimization information from the wireless communication node 512 and the wireless communication node 514, even if the system does not predict that the user device 220 will move to 520b1. .

Therefore, when the user equipment 220 is separated from the wireless signal coverage area 512 of the wireless communication node 512, the wireless communication signal is not required to be re-scanned, but the wireless communication node 514 can be immediately connected according to the signal optimization information of the wireless communication node 514. In this way, the network connection interruption time can be minimized, and in the optimal state, the connection service that the user equipment 220 is performing is not interrupted, and the seamless connection is achieved.

In contrast, conventional techniques have been forced to disconnect the wireless communication signal since the user device 220 has left the wireless signal coverage range 512 of the wireless communication node 512, and the network connection is interrupted. line.

Although the present invention has been described above in connection with the preferred embodiments, it is not intended to limit the invention. It is to be understood by those skilled in the art that such modifications and variations can be made without departing from the spirit and scope of the invention, and the scope of the invention is defined by the scope of the appended claims.
