Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
When the configuration data of the service is transmitted for the wireless access device through the controller, the controller may divide the configuration data sent to the wireless access device into sent data and unsent data, for example, two different databases may be used to manage the sent configuration data and unsent configuration data, respectively, when the wireless access device is disconnected and re-accesses the controller, the controller only sends the unsent configuration data to the wireless access device, and when an acknowledgement message returned by the wireless access device is received, the configuration data is moved from the unsent database to the sent database.
As shown in fig. 1, the wireless access device and the controller perform data transmission through a wireless network. The wireless Access device may be a wireless Access Point (AP), a wireless router, and the like, and provides services such as Access and routing for the user equipment. The wireless network may be a mobile communication network, e.g., a 2G/3G/4G/5G network, etc. The controller may be a device having an information processing function for managing and controlling a wireless access device, such as a server, a computer, and the like, and may access the wireless network through a wired or wireless manner, for example, may be connected to an access network device or a core network device of the wireless network through an optical fiber.
For the convenience of understanding of the embodiments of the present invention, the following description will be further explained with reference to specific embodiments, which are not to be construed as limiting the embodiments of the present invention.
Fig. 2 is a flowchart of a data transmission method according to an embodiment of the present invention. As shown in fig. 2, the method specifically includes:
s210, the controller receives a registration message sent by the wireless access device, wherein the registration message is used for establishing the connection between the controller and the wireless access device.
The wireless access equipment sends a registration message to the controller every time the wireless access equipment is on line, and the controller sends service configuration data to the wireless access equipment which is successfully registered according to the service configuration. The wireless access device is on-line, which means that the wireless access device establishes connection with the controller.
S220, the controller sends configuration data to be sent corresponding to the wireless access equipment, wherein the configuration data to be sent refers to configuration data which is not sent or is not sent successfully.
When the controller sends the configuration data to the wireless access device, the wireless access device may be in an online state or an offline state, and when the wireless access device is in the offline state, the configuration data sent by the controller to the wireless access device cannot be received by the wireless access device, and therefore is marked as unsuccessfully sent configuration data.
When the wireless access device is online, the controller may directly send the configuration data to be sent to the wireless access device.
When the wireless access device is not on-line, the controller may generate incremental data that is different from configuration data that has been successfully transmitted, based on the configuration data to be transmitted. And when the wireless access equipment is on line, the controller sends the incremental data to the wireless access equipment.
S230, the controller receives a confirmation message sent by the wireless access device, where the confirmation message indicates that the wireless access device has successfully received the configuration data to be sent.
When the wireless access equipment successfully receives the configuration data sent by the controller, the wireless access equipment returns a confirmation message to the controller, so that the controller can know that the configuration data sent at this time is delivered.
S240, the controller marks the state of the configuration data to be sent as sent according to the confirmation message.
The controller may mark the configuration data that has been successfully received by the wireless access device as sent, for example, the controller may first store the configuration data that has not been sent or that has not been successfully sent in the incremental database, and when the configuration data has been successfully sent, the controller may transfer the configuration data that has been successfully received by the wireless access device in the incremental database to the backup database, and may delete the configuration data that has been successfully received by the wireless access device from the incremental database. The "incremental database" and the "backup database" are only examples, and other databases capable of distinguishing the two configuration data are within the scope of the present invention and will not be described again.
In the specific implementation process of the embodiment of the present invention, an authentication mechanism may be further added to more accurately provide services for the wireless access device, which is further described below with reference to fig. 3. The embodiment shown in fig. 3 is a preferred embodiment of the embodiment shown in fig. 2, and can be understood by reference.
S310, the controller receives a registration message sent by the wireless access device, where the registration message is used to establish a connection between the controller and the wireless access device, and the registration message may include a first state identifier, where the first state identifier is used to identify one data transmission between the controller and the wireless access device.
S320, the controller judges whether the wireless access device is registered for the first time.
The controller may determine by the first status identification included in the registration message, or may determine whether the wireless device has stored its mapping table entry locally, etc.
S330a, the controller generates a mapping table entry for the wireless device when the wireless device is first registered.
When the wireless access device registers for the first time, the wireless access device may send a first status identifier to the controller, where the first status identifier is used to identify that the wireless access device registers for the first time with the controller. The controller receives a first state identifier sent by the wireless access equipment, and generates a mapping table item of the wireless access equipment, wherein the mapping table item comprises a corresponding relation between the first state identifier and the wireless access equipment. Specifically, the controller may add a mapping table entry including a correspondence of the first state identification and the wireless access device in a mapping table. Each table entry of the mapping table stores a corresponding relationship between a wireless access device and a state identifier of the wireless access device.
S330b, when the registration is not the first registration, the controller determines whether the second status identifier in the mapping table entry corresponding to the wireless access device is consistent with the first status identifier.
When the wireless access device is not registered for the first time, the wireless access device may send the status identifier of the last data transmission between the wireless access device and the controller to the controller as the first status identifier. The controller may determine whether the first status flag and the second status flag are consistent. When the configuration data is inconsistent with the configuration data, the controller sends all the configuration data corresponding to the wireless access equipment, that is, the configuration data to be sent and the configuration data sent in the controller need to be sent to the wireless access equipment; when consistent, step S340 is performed.
S340, the controller sends to-be-sent configuration data corresponding to the wireless access device, where the to-be-sent configuration data is unsent or unsuccessfully-sent configuration data.
This step is similar to the aforementioned step S220 and can be understood by cross-reference.
S350, the controller receives a confirmation message sent by the wireless access device, where the confirmation message indicates that the wireless access device has successfully received the configuration data to be sent, and the confirmation message may also carry a third status identifier, where the third status identifier is used to identify current data transmission between the controller and the wireless access device.
After the wireless access device successfully receives the configuration data sent by the controller, the wireless access device may notify the controller so that the controller performs corresponding processing on the configuration data that is sent.
Meanwhile, the wireless access device may further generate a third status identifier and send the third status identifier to the controller.
And S360, the controller updates the mapping table corresponding to the wireless access equipment according to the third state identification.
After receiving the acknowledgement message sent by the wireless access device and obtaining the third state identifier, the controller needs to update the state of the wireless access device in the mapping table entry corresponding to the locally stored wireless access device, that is, the third state identifier is stored in the mapping table as the state identifier of the wireless access device, where the controller may directly replace the second state identifier with the third state identifier, or the controller may also use the third state identifier as the latest state identifier of the wireless access device, and so on. Therefore, the data to be transmitted and the transmitted data can be transmitted by taking the data identified by the third state as a demarcation point, so that the data transmission is clearer.
After step S360, when the registration message sent by the wireless access device is received again, steps S310, S320, S330a, S330b, S340, S350, and S360 may be iteratively executed. The first status flag, the second status flag and the third status flag in the step are adjusted correspondingly according to the content carried by the actual registration message and the confirmation message.
It should be noted that the "first state identifier", "second state identifier", and "third state identifier" in the embodiment of the present invention may be a timestamp, a random field, or a time. In other words, the time when the wireless access device and the controller transmit data may be used to mark the data transmission, a unique field may be randomly generated for each data transmission to mark the current data transmission, and the specific number of data transmissions may be used to mark the current data transmission, such as the first data transmission or the "N" th data transmission, where N may be a natural number.
It should be understood that the terms "first", "second", etc. in the embodiments of the present invention are used only for distinguishing similar features and are not intended to limit the present invention.
The invention is further described with reference to the following drawings and specific examples.
As shown in fig. 4, the wireless access device is deployed in a bus to provide services to passengers. When the bus passes through a tunnel or a place with weak signals, the controller deploys configuration data of a service to the wireless access equipment. The method comprises the following specific steps:
401, when the wireless access device registers to the controller for the first time, the timestamp status identifier of the wireless access device is carried in a registration message. After receiving the registration message of the wireless access device, the controller generates a mapping table item of the wireless access device, wherein the mapping table item comprises a corresponding relation between the wireless access device and the timestamp status identifier of the wireless access device. For example, the timestamp status identifier carried in the registration message sent by the wireless access device may be 0, and therefore, the timestamp status identifier corresponding to the wireless access device on the controller may also be 0 at this time.
The controller generates 402 configuration data for service a and then directly sends the configuration data for service a to the wireless access device. The controller may generate the configuration data of the service a according to the configuration data generation instruction sent by the administrator through the interface after receiving the configuration data generation instruction.
403, after the configuration is successful, the radio access device may update the local status identifier with a local timestamp "2015/11/1108: 00: 00" (if the current time of the device is 2015/11/1108:00:00 "), and then send a confirmation message to the controller, where the confirmation message may carry the timestamp status identifier" 2015/11/1108:00:00 "of the radio access device. After the controller receives the confirmation message, the timestamp status flag of the mapping table entry of the wireless access device is updated to be "2015/11/1108: 00: 00".
The controller may periodically send a heartbeat or a detection message to the wireless access device to detect if the wireless access device is online 404. For example, after a bus enters a tunnel, the controller finds that the wireless access device is not on-line through detection, and then notifies a patch (incremental data) generation/detection module to request a new service configuration of the wireless access device to generate the patch, that is, to identify a data state to be sent as a state to be sent.
405, the controller configures configuration data of service B for the radio access equipment, where service B is a new service.
406, the Patch generating/detecting module generates a Patch B for the new service B, and the Patch B is not directly issued to the wireless access device.
407, after the bus passes through the tunnel, the wireless access device sends a registration message to the controller again, the registration message has a local timestamp status identifier of the wireless access device, and the timestamp status identifier is a timestamp status identifier carried by a last time of sending a confirmation message by the wireless access device.
408, after the controller receives the registration message, the controller searches whether the patch exists in the wireless access device. The presence of the patch B for the wireless device is found and the timestamp status identifier in the registration message is compared to the device timestamp status identifier stored on the controller. If both are "2015/11/1108: 00: 00", the controller sends patch B only to the radio access device.
409, the wireless access equipment receives the patch B sent by the controller and then configures the configuration on the wireless access equipment. If the configuration is successful, a new timestamp status identification "2015/11/1109: 01: 01" is re-generated on the wireless access device (assuming the device current time is 2015/11/1109: 01:01) and an acknowledgement message is returned to the controller along with the timestamp status identification "2015/11/1109: 01: 01". And if the configuration fails, returning a configuration failure message to the controller, and carrying the timestamp of the last successful configuration.
After the controller receives the confirmation message returned by the wireless access equipment, the corresponding state identifier of the wireless access equipment in the controller is updated by using the timestamp state identifier '2015/11/1109: 01: 01' carried by the confirmation message, and the patch B is submitted to a database, if the submission is successful, the patch B is deleted, wherein the sent data is stored in the database.
