Description

Communication device and data communication method

technical field

The present invention relates to the technical field of communication, in particular, to a communication device and a data communication method.

Background technique

In 802.11, a new working group FILS (fast initial link setup, fast initial link setup) was established. The purpose of this working group is to solve how a large number of terminals can quickly communicate with an AP (access point, access point) in a WLAN network at the same time. access point) to establish an initial link. The project team's requirement is that 100 terminals can establish connections with the AP within 1 second.

During the discussion of the solution, the working group proposed such a solution: the AP sends a Probe response (probe response frame) in the form of a broadcast message, so that all STAs (terminals) can listen and must parse it , which can reduce the possibility of the STA sending a Proberequest (probe request frame), reduce signaling interaction, and improve the network access efficiency of the STA.

However, for those STAs that have established a connection with the AP, according to the above method, they must also receive and analyze the Probe response message broadcast by the AP, which will cause additional power consumption for these STAs that have already connected to the network.

Therefore, a new communication solution between the STA and the AP is needed, so that the communication device that has already connected to the network does not analyze the broadcast probe response frame, thereby avoiding unnecessary power consumption overhead.

Contents of the invention

Based on the above problems, the present invention proposes a new communication scheme between STA and AP, so that the communication equipment that has already entered the network will not analyze the broadcast probe response frame, thereby avoiding unnecessary power consumption overhead.

In view of this, the present invention proposes a communication device, including: a data interaction module for receiving a broadcast message frame; a data processing module for obtaining the type of the broadcast message frame and the source address of the broadcast message frame, wherein, if the When the broadcast message frame is a probe response frame and the source address of the broadcast message frame is the same as the media access control address of the access point where the communication device has established a network connection, the communication device discards the probe response frame The remaining part. In this technical solution, the communication device can be a STA, such as a mobile phone or a tablet, etc., the data processing module can be a chip module for data processing in the communication device, and the data interaction module is equivalent to a signal transceiving device and an antenna. The communication device obtains information from the received broadcast message frame, for example, the communication device has established a network connection with access point A, then when the communication device receives the probe response frame broadcast by access point A, and parses the probe response When the source address of the frame is the same as the MAC address of the access point A that establishes the connection, the rest of the probe response frame (except for the other parts used to obtain the type and source address) will not be parsed, so as to avoid the communication device from generating Unnecessary power overhead.

In the above technical solution, preferably, the data processing module determines the type of the broadcast message frame from the frame control field of the header of the MAC frame of the broadcast message frame. In this technical solution, only a part of the MAC frame header of the broadcast message frame can be parsed to determine the type of the broadcast message frame, so as to facilitate further judgment, so that when the broadcast message frame is a communication device that has established network communication When the access point broadcasts the probe response frame, no further parsing is performed to avoid unnecessary power consumption.

In the above technical solution, preferably, the data processing module determines the type of the broadcast message frame from the type subfield and the subtype subfield of the frame control field of the frame header of the medium access control frame of the broadcast message frame. In this technical solution, when the specific communication device can analyze the value of the type subfield (Type) in the frame control (FC) domain (Type) is "00" and the value of the subtype subfield (Subtype) is "0101", then determine the The broadcast message frame is a probe response frame, which is convenient for further judgment, so when the broadcast message frame is a probe response frame broadcast by an access point where the communication device has established network communication, no further analysis is performed to avoid unnecessary For power consumption, of course, other values of the type subfield and subtype subfield may also be used to identify the type of the probe response frame, which will not be repeated here.

In the above technical solution, preferably, it also includes: a data recording module, recording the received signal strength of the broadcast message frame as a first value, and recording the received signal from the network connection with the communication device before receiving the broadcast message frame The received signal strength of the last data frame of the access point is a second value; wherein, the data processing module determines the medium access of the access point where the source address of the broadcast message frame has established a network connection with the communication device When the control addresses are different, it is further determined whether the first value is greater than the second value, and if so, the communication device processes the remaining part of the probe response frame. In this technical solution, the communication device can measure and record the received signal strength of the received signal, for example, the value of RSSI (Received Signal Strength Indication, received signal strength index) can be used specifically. Assuming that the communication device has established a network connection with access point A, when the communication device performs data communication with access point A, the communication device can measure and record the RSSI value of the data frame during the data communication process, for example, when When the communication device determines that the source address in the probe response frame is different from the MAC address of the access point A that has established the connection, the communication device may also record that the received signal strength of the received probe response frame is RSSI1, and the record is consistent with the MAC address of the access point A. The received signal strength of the data frame of A's latest data communication is RSSI2. If RSSI1>RSSI2, the probe response frame can be processed to switch to the other access point, so as to obtain better communication effect.

In the above technical solution, preferably, the data processing module further determines that the second Whether a value is smaller than the second value, if yes, the communication device discards the rest of the probe response frame. In this technical solution, the received signal strength of the probe response frame received by the communication device from other access points is RSSI1, and the source address of the probe response frame is different from the MAC address of the access point A that has established the connection, and Record the received signal strength of the data frame of the latest data communication with access point A as RSSI2. If RSSI1<RSSI2, the remaining part of the received probe response frame can be discarded without switching to ensure that the communication device obtains better communication effect.

According to another aspect of the present invention, a data communication method is also proposed, including: receiving a broadcast message frame; obtaining the type of the broadcast message frame and the source address of the broadcast message frame; if the broadcast message frame is a detection When responding to a frame and the source address of the broadcast message frame is the same as the MAC address of the access point with which the receiver of the broadcast message frame has established a network connection, the remaining part of the probe response frame is discarded. In this technical solution, the communication device can be a STA, such as a mobile phone or a tablet, etc., the data processing module can be a chip module for data processing in the communication device, and the data interaction module is equivalent to a signal transceiving device and an antenna.

In the above technical solution, preferably, the step of obtaining the type of the broadcast message frame includes: determining from the type subfield and the subtype subfield of the frame control field of the frame header of the media access control frame of the broadcast message frame The type of the broadcast message frame. In this technical solution, when the specific communication device can analyze the value of the type subfield (Type) in the frame control (FC) domain (Type) is "00" and the value of the subtype subfield (Subtype) is "0101", then determine the The broadcast message frame is a probe response frame, which is convenient for further judgment, so when the broadcast message frame is a probe response frame broadcast by an access point where the communication device has established network communication, no further analysis is performed to avoid unnecessary For power consumption, of course, other values of the type subfield and subtype subfield may also be used to identify the type of the probe response frame, which will not be repeated here.

In this technical solution, the communication device can measure and record the received signal strength of the received signal, for example, the value of RSSI (Received Signal Strength Indication, received signal strength index) can be used specifically. Assuming that the communication device has established a network connection with access point A, when the communication device performs data communication with access point A, the communication device can measure and record the RSSI value of the data frame during the data communication process, for example, when When the communication device determines that the source address in the probe response frame is different from the MAC address of the access point A that has established the connection, the communication device may also record that the received signal strength of the received probe response frame is RSSI1, and the record is consistent with the MAC address of the access point A. The received signal strength of the data frame of A's latest data communication is RSSI2. If RSSI1>RSSI2, the probe response frame can be processed to switch to the other access point, so as to obtain better communication effect.

In the above technical solution, preferably, further comprising: when the source address of the broadcast message frame is inconsistent with the media access control address of the access point where the communication device has established a network connection, if the first value is less than the set If the second value is not specified, the remainder of the Probe Response frame is discarded.

Fig. 3 shows a specific flow chart of processing received broadcast message frames in the BSS according to an embodiment of the present invention.

For STAs in the BSS (basis service set, basic service set), that is, only one AP serves many STAs (including those on the network and those about to join the network), the specific process for the STA to process the received broadcast message frame is as follows: As shown in Figure 3, including:

Step 302, the STA receives the broadcast message frame. Since there is only one AP, ideally, for the STA that is under the BSS and has established a network connection with the AP, the received broadcast message frame should be from the BSS AP.

Step 304, judging the type of the broadcast message frame. Specifically, the type of the broadcast message frame can be obtained through the type subfield and subtype subfield of the frame control field (FC, Frame Control) of the frame header of the MAC (Medium Access Control) frame of the broadcast message frame . A table can be established in advance to record the correspondence between the type of the broadcast message frame and the values of the type subfield and the subtype subfield, so that the type of the frame control field of the frame header of the media access control frame of the received broadcast message frame can be viewed The value of the subfield and the subtype subfield to determine the specific type of the broadcast message frame, as shown in Table 1:

Table 1

Then, according to the records in Table 1, when the type subfield value of the received broadcast message frame is "00" and the subtype subfield value is "0101", it can be determined that the type of the broadcast message frame is a probe response frame.

Step 306, if it is determined in step 304 that the type of the broadcast message frame received is a probe response frame, then directly discard the remaining part of the probe response frame (in the process of determining its type, such as the type subfield and the subtype subfield and other parts are parsed, so the "remaining part" is the other parts before this), so as to avoid unnecessary power consumption loss to the STA.

In step 308, if it is determined in step 304 that the type of the received broadcast message frame is not a probe response frame, the STA performs the next operation process on the broadcast message frame.

The above describes the processing process of the received broadcast message frame when the STA is in a single BSS environment in conjunction with Figure 3, but the situation in the real environment is more complicated, and a STA often cannot ensure that it is only in one BSS , and is very likely to exist in OBSS (overlapping Basis Service Set, overlapping basic service set), that is, multiple APs use the same communication channel bandwidth to serve many STAs. For the STA in the OBSS environment, the following will describe in detail with reference to FIG. 4 .

Fig. 4 shows a specific flow chart of processing received broadcast message frames in OBSS according to an embodiment of the present invention.

As shown in Figure 4, the specific process of processing the received broadcast message frame in OBSS according to the embodiment of the present invention includes:

In step 402, the STA receives the broadcast message frame.

Step 404, judge the type of the broadcast message frame. Specifically, you can refer to step 304 in FIG. 3 and the corresponding description for judgment. The value of the type subfield and the subtype subfield of the frame control field of the header is obtained to determine whether the type of the broadcast message frame is a probe response frame, wherein, if yes, enter step 406, otherwise enter step 410.

Step 406, if the broadcast message frame is a probe response frame, then further obtain the source address information of the probe response frame; at the same time, for the STA connected to the network, the MAC address of the AP that has established a network connection with it can be obtained, so as to judge the probe response Whether the source address information of the frame is the same as the MAC address of the AP, if yes, go to step 412, otherwise go to step 408.

Step 408, when the source address information of the probe response frame is not the same as the MAC address of the AP, it means that the probe response frame comes from another BSS (different from the BSS where the current STA is located), and the STA can check the network information of the two BSSs. The status is judged so as to be in the BSS with better network status, so as to obtain better network conditions.

Specifically, when the STA is performing data communication with the connected AP, it records the received signal strength of the data frame of the data communication, such as using the RSSI value; at the same time, the STA can obtain the RSSI value of the currently received probe response frame. Assuming that the received signal strength of the probe response frame is RSSI1, and the received signal strength of the recorded data frame of the most recent data communication with the connected AP is RSSI2, then, if RSSI1>RSSI2, it means that the network status of another BSS is more OK, then go to step 410, that is, the STA can switch to the other BSS by processing the probe response frame, so as to obtain a better communication effect. If RSSI1<RSSI2, it means that the network status of the current BSS is better , then enter step 408, that is, the STA does not need to handover.

Step 410, perform the next operation on the received broadcast message frame.

Step 412, directly discard the remaining unparsed part of the broadcast message frame.

The above describes the technical solution of the present invention in detail in conjunction with the accompanying drawings. Considering that in related technologies, all STAs need to parse the received broadcast probe response frames, so that STAs that have already connected to the network will generate unnecessary circuit consumption. Therefore, this The invention proposes a communication device and a data communication method, so that the communication device that has already entered the network does not analyze the broadcast probe response frame, thereby avoiding unnecessary power consumption overhead.

For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
