Detailed Description

Fig. 2 is a schematic structural diagram of a communication system according to an embodiment of the present disclosure, where the communication system includes a request end And a receiving end, And the request end And the receiving end communicate via a Control And Provisioning Protocol (CAPWAP) of a Wireless Access point. The CAPWAP protocol is a general tunnel protocol, and can be used to complete basic protocol functions such as Access Point (AP) discovery Access Controller (AC), and defines how to manage and configure Access points. In a communication system, the requesting end may be an Access point device, such as Wireless Terminal Access Points (WTPs), and the receiving end may be an Access Controller (AC). The CAPWAP can realize the automatic discovery of WTPs to the AC and the operation and maintenance of state machines of the WTPs and the AC, realize the management and the service configuration issuing of the AC to the WTPs, and provide a reliable mechanism for controlling the receiving and sending of messages and data messages.

The CAPWAP protocol is realized based on a UDP protocol and respectively provides a control channel and a data channel. A control channel, for which 5246 port is used, and a data channel, for which 5247 port is used, are provided separately. The CAPWAP provides a reliable transmission mechanism for the control channel, and for the control packet, the packet structure thereof is as shown in fig. 3, and includes: a Message Type (Message Type), a Sequence Number (SN), a Message Element Length (Message Element Length), a Flag (Flag), and a Message Element (Message Element).

The CAPWAP control messages are necessarily paired, the request end sends a request message, the receiving end needs to send a response message to the request end after processing the request message, and the request end considers that the last request message is successfully sent after receiving the response message and continues to send subsequent request messages. If the request end does not receive the response message in the specified time, the request end retransmits the last request message, and the retransmission interval can be 3S and the retransmission times can be 5 times in the default case. The Type of the Message is identified by a Message Type, where the Message Type of the request Message must be odd, and the Message Type of the response Message is equal to the request Message Type + 1. The Sequence Number (SN) in the CAPWAP control message is used for preventing mess, can be generated by a request end, the value range of the SN can be 0-255, the SN is added with 1 when the request end sends a request message, and when the SN exceeds 255, the SN is turned over to be 0. The SN carried in the CAPWAP response message must be consistent with the SN of the corresponding request message, and if not, the message is regarded as an illegal message and is directly discarded. For example, as shown in fig. 1, assuming that the message Type in the request message sent by the requesting end is 1 and the sequence number SN is 1, the receiving end returns the Type in the corresponding response message is 2 and the SN is 1.

Fig. 4 is a flowchart illustrating an information processing method according to an embodiment of the present application, where the method may be applied to the communication system shown in fig. 2, and referring to fig. 4, the method includes the following steps.

Step 401: the access point equipment sends a service request message of a first service to the access controller, wherein the service request message comprises a first queue identification and request information.

The access point device comprises at least two buffer queues, the first queue identification is used for identifying the first buffer queue, the first buffer queue belongs to the at least two buffer queues and is used for buffering the message of the first service, and the request information is used for requesting to process the first service.

The access point device may be a wireless terminal access point device (WTPs), where the WTPs may include multiple buffering queues, and there may be multiple services, and there may be a correspondence between the multiple services and the multiple buffering queues, and a buffering queue corresponding to each service may be used to buffer a packet corresponding to the service. The first service may be any one of a plurality of services, the first buffer queue may be any one of a plurality of queues, and the first queue identifier is used to identify the first buffer queue, for example, the first identifier may be a queue number of the first buffer queue.

Specifically, when the WTPs need to send request information of the first service to the AC, the WTPs may buffer a service request packet of the first service in the first buffer queue, and send the service request packet through the first buffer queue, where the service request packet includes the first queue identifier and the request information.

It should be noted that, the correspondence between the multiple services and the multiple buffer queues may also be referred to as a correspondence between the services and the buffer queues, and the correspondence may include a one-to-one, one-to-many, or many-to-one relationship, that is, one service may correspond to one buffer queue, or one service may correspond to multiple buffer queues, or multiple services may correspond to one buffer queue, which is not specifically limited in this embodiment of the present application.

In addition, the correspondence relationship may be set in advance. For example, if the communication of a certain service is frequent and the number of messages of the service is large, one or more buffer queues may be allocated to the service; or, the communication of some services is sparse, so that the number of messages of the services is small, and the services can be allocated to share one buffer queue.

For convenience of understanding, the example that the plurality of services includes 4 services (e.g., service 1 to service 4), the plurality of buffer queues includes 4 buffer queues (e.g., queue 1 to queue 4), and the correspondence between the 4 services and the 4 buffer queues is described as the following table 1.

TABLE 1

Step 402: the access controller receives a service request message from the access point device, wherein the service request message comprises a first queue identifier and request information.

The access controller may also include at least two buffer queues, and the first queue identifier may also be used to identify a first buffer queue of the at least two buffer queues of the access controller, where the first buffer queue is used to buffer the packet of the first service. In addition, the at least two buffering queues may be a plurality of buffering queues, and there may also be a correspondence between a plurality of services of the access controller and the plurality of buffering queues thereof, where the correspondence may be a one-to-one, one-to-many, or many-to-one relationship, and the correspondence may be allocated in advance. For a detailed description of the corresponding relationship, reference may be specifically made to the related description of the corresponding relationship in step 401, and details are not repeated herein in this embodiment of the application.

After the access point device sends the service request message of the first service to the access point device, the access controller may receive the service request message. The access controller may cache the service request packet in a first cache queue corresponding to the first queue identifier according to the first queue identifier included in the service request packet. Furthermore, when the access controller processes the service request message, the access controller may obtain the service request message from the first buffer queue, obtain request information in the service request message, and process the first service according to the request information.

Step 403: and the access controller sends a service response message to the access point equipment, wherein the service response message comprises the first queue identifier and response information, and the response information is used for indicating that the service request message is successfully received.

After receiving a service request message of a first service, the access controller may send a corresponding service response message to the access point device through the first buffer queue, where the service response message includes a first queue identifier and response information used to indicate that the service request message is successfully received.

The service request message and the service response message correspond to each other, that is, the service request message and the service response message are a pair of messages. Assuming that the message Type in the service request message is 3 and the sequence number SN is 3, the message Type in the service response message is 4 and the sequence number SN is 3.

Step 404: the access point equipment receives a service response message from the access controller, wherein the service response message comprises the first queue identification and response information.

When the access point device receives the service response message, the service response message may be cached in the first buffer queue, and when the access point device processes the service response message, the access point device may obtain the service response message from the first buffer queue, and determine that the service request message of the first service is successfully received according to the response information in the service response message.

For example, the communication between the WTPs and the AC includes messages of service 1 and service 2, where service 1 uses queue No. 0 and service 2 uses queue No. 1, and the message distribution of service 1 and service 2 can be as shown in fig. 5, so that messages of different services are transmitted through different buffer queues, and the problem that the request messages of other services of the WTPs cannot be sent and processed in time due to excessive request messages of a certain service and excessively long AC processing time is avoided.

Further, referring to fig. 6, before the access point device sends the service request message of the first service to the access controller (i.e. step 401), the access point device may further generate the service request message, that is, the method further includes: step 401a and step 401 b.

Step 401 a: and the access point equipment determines a first buffer queue from the corresponding relation between the service and the buffer queue according to the first service.

When the access point device needs to send request information of the first service to the access controller, the access point device may determine, according to the first service, the first buffer queue from a correspondence between a preset service and the buffer queue, that is, determine the buffer queue corresponding to the first service.

Step 401 b: and the access point equipment generates a service request message of the first service according to the first queue identification and the request information of the first buffer queue.

After the access point device determines that the cache queue corresponding to the first service is the first cache queue, the access point device may generate a service request packet of the first service according to the identifier of the first cache queue (i.e., the first queue identifier) and the request information of the first service.

Specifically, when a first service in the access point device needs to send request information, the first service may deliver the request information to a first buffer queue allocated in advance, and the CAPWAP may write an identifier of the first buffer queue into a CAPWAP header of the first service when sending the request information, and then send the identifier, that is, write the identifier of the first buffer queue into a service request message. Furthermore, after the access controller receives the service request message, the access controller can analyze the CAPWAP header to obtain a first queue identifier, so that the service request message is cached in a first buffer queue to wait for processing.

Accordingly, referring to fig. 6, before the access controller sends the service response message to the access point device (i.e., step 403), the access point device may further generate the service response message, that is, the method further includes: step 403a and step 403 b.

Step 403 a: and the access controller determines the first buffer queue from the corresponding relation between the service and the buffer queue according to the first service.

When the access controller needs to send the response information of the first service to the access point device, the access controller may determine, according to the first service, the first buffer queue from a preset correspondence between the service and the buffer queue, that is, determine the buffer queue corresponding to the first service.

Step 403 b: and the access controller generates a service response message of the first service according to the first queue identification and the response information of the first buffer queue.

After the access controller determines that the cache queue corresponding to the first service is the first cache queue, the access controller may generate a service response packet of the first service according to the identifier of the first cache queue (i.e., the identifier of the first queue) and the response information of the first service.

Specifically, when the access controller processes a service of the first service and needs to send a response message, the service may deliver the response message to a first buffer queue allocated in advance, and the CAPWAP may write an identifier of the first buffer queue into a CAPWAP header of the CAPWAP when sending the response message, and then send the identifier, that is, write the identifier of the first queue into the service response message. Furthermore, after the access point device receives the service response message, the access point device may analyze the CAPWAP header to obtain a first queue identifier, so as to cache the service response message in the first buffer queue for processing.

Further, the service request packet and the service response packet are both CAPWAP control packets, and headers of the service request packet and the service response packet both include wireless dedicated information (wireless specific information), that is, a Header of the CAPWAP control packet includes wireless dedicated information, and the wireless dedicated information is used to indicate the first queue identifier.

As shown in fig. 7, a structural diagram of a CAPWAP header is shown, where the CAPWAP header includes a fixed field and an extension field, the inherent field includes a CAPWAP Preamble (CAPWAP Preamble), a Header Length (HLEN), a Radio frequency ID (rid), a Radio frame identifier (WBID), a data frame identifier (T), a packet flag (F), a packet end flag (L), a bit option flag (W), a bit selection flag (M), a bit survival flag (K), a Reserved flag (Flags), a packet identifier (Fragment ID), a packet Offset (Fragment Offset), a Reserved code (Reserved, which is denoted by Rsvd in fig. 7), and a load (Payload), and the extension field may include a Wireless MAC Address (Radio MAC Address) and Wireless dedicated Information (Wireless Information). When the value of the bit option mark W is 1, a wireless special information option exists; when the value of the bit option flag M is 1, the wireless MAC address option exists. The detailed description of each field in the CAPWAP header can be found in the CAPWAP protocol, which is not specifically described in the embodiments of the present application.

In the embodiment of the application, the information for indicating the first queue identifier may be added to the header of the CAPWAP packet by using the wireless dedicated information. Wherein the CAPWAP protocol specifies that the bit option flag W has a value of 1 if a wireless specific information field is to be used.

The structure of the wireless dedicated information is shown in fig. 8, and includes a Length (Length) indicating the Length of Data and Data (Data). Illustratively, in fig. 8, Length occupies 8bits as an example, and the Length of Data is determined by the specific value of Length.

In the embodiment of the present application, Data is redefined, and the structure of the Data field is defined as a TLV structure, that is, the TLV structure includes a Type (Type), a Length (Length), and a Value (Value). Exemplarily, as shown in fig. 9, it is a schematic diagram of the structure of Data.

Alternatively, Type may be set to 1, Length may be set to 2, the Value of Value represents the first queue identifier (for example, the Value of Value is the actual queue number), and the Value Type of Value may be set to a short integer, which has a Value range of 0 to 65536. In practical application, the number of the maximum supported buffer queues can be set according to the performance of the device.

In the information processing method provided by the embodiment of the application, the access point device and the access controller both include at least two buffer queues, and when the access point device and the access controller send messages of different services, the access point device and the access controller can send respective messages through the buffer queue corresponding to each service, and carry the identifier of the buffer queue in the message, so that an opposite end can buffer the received messages in the corresponding buffer queue for processing, thereby avoiding the problem that the request messages of a certain service are too many and the request messages of other services cannot be sent and processed in time, and improving the performance of service processing.
