Abstract

The present invention discloses a signal strength measurement method, a wireless gateway device, and a readable storage medium. The signal strength measurement method obtains the STA identification field of a station STA accessing a wireless access point AP, and searches for a signal strength algorithm associated with the STA identification field. If no associated signal strength algorithm is found, it is considered that the STA accesses the AP for the first time. At this time, by traversing and calculating multiple preset signal strength algorithms, the signal strength algorithm applicable to the STA accessing for the first time is matched, and the matched first signal strength algorithm is associated with the STA. Therefore, during the roaming process of the STA in the current wireless local area network, the first signal strength algorithm can be directly called to calculate the RSSI of the STA. Thus, the present invention can be compatible with STAs of different manufacturers, match the most suitable signal strength algorithm for the STA, so as to obtain accurate RSSI, and avoid the problem of incorrect RSSI calculation due to poor compatibility during the roaming process.

Description

Technical Field

[0001] The present invention relates to the technical field of wireless local area networks, and particularly to a signal strength measurement method, a wireless gateway device, and a readable storage medium. Background Art

[0002] WiFi (Wireless Fidelity, a wireless local area network based on the IEEE 802.11b standard) is a very flexible wireless data communication system. It can either be an effective extension of a traditional wired local area network or form a standalone network, greatly expanding the flexibility of wireless access networks.

[0003] In the WiFi technology, a STA (Station) usually obtains network services by connecting to an AP (Access Point). However, since the coverage area of a single AP is not large and the signal attenuation is significant after passing through walls, when deploying multiple APs for large - area coverage, multiple APs with the same SSID (Service Set Identifier) name and authentication encryption method are often deployed to build a roaming network. To enable a STA to roam between multiple APs, the STA preferentially selects the AP with the maximum RSSI (Received Signal Strength Indication) at the current location during movement for access. However, the RSSI algorithms applicable to STAs from different manufacturers are not the same. Therefore, during the roaming process, it is easy for the gateway device to make an incorrect judgment on the RSSI of the STA, thereby affecting the use of the network and resulting in a poor user experience. Summary of the Invention

[0004] The following is an overview of the subject matter described in detail herein. This overview is not intended to limit the scope of protection of the claims.

[0011] The signal strength measurement method provided in the first aspect of the embodiments of the present invention has at least the following beneficial effects: When the STA switches the accessed AP during the roaming process in the wireless local area network, at this time, the RSSI is calculated according to the association information uploaded by the STA accessing the AP. If the STA identification field of the STA can be found in the gateway, it means that the STA is not accessing the current wireless local area network for the first time. At this time, the signal strength algorithm associated with the STA identification field can be directly called to calculate the RSSI; if the STA identification field of the STA cannot be found in the gateway, it means that the STA is accessing the current wireless local area network for the first time. At this time, the gateway calculates the first RSSI and RCPI in a conventional manner, and based on a plurality of preset signal strength algorithms, matches a first signal strength algorithm suitable for calculating the RSSI of the STA, and finally associates the first signal strength algorithm with the STA identification field for calling when the STA accesses the current wireless local area network again; The embodiments of the present invention match the signal strength algorithm applicable to the STA accessing for the first time by traversing and calculating a plurality of preset signal strength algorithms, and associate the matched first signal strength algorithm with the STA, so that during the roaming process of the STA in the current wireless local area network, the first signal strength algorithm can be directly called to calculate the RSSI of the STA. Therefore, the most suitable signal strength algorithm can be called for STAs of different manufacturers to obtain accurate RSSI, avoiding the problem of incorrect RSSI calculation due to poor compatibility during the roaming process.

[0012] The second aspect of the embodiments of the present invention provides a wireless gateway device, including at least one processor and a memory for communicatively connecting with the at least one processor; the memory stores instructions that can be executed by the at least one processor, and the instructions are executed by the at least one processor to enable the at least one processor to execute the foregoing signal strength measurement method.

When the STA switches the accessed AP during the roaming process in the wireless local area network, at this time, the RSSI is calculated according to the association information uploaded by the STA accessing the AP. If the STA identification field of this STA can be found in the gateway, it means that this STA is not accessing the current wireless local area network for the first time. At this time, the signal strength algorithm associated with the STA identification field can be directly called to calculate the RSSI; if the STA identification field of this STA cannot be found in the gateway, it means that this STA accesses the current wireless local area network for the first time.

[0025] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] It should be noted that although module division is performed in the circuit structure schematic diagram, in some cases, it can be different from the module division in the circuit structure schematic diagram. The terms "first", "second", etc. in the specification and claims are used to distinguish similar objects and do not have to be used to describe a specific order or sequence.

[0027] The regulations of the signal strength algorithm for STAs (Stations) from different manufacturers are not consistent. Taking mobile phone terminals as an example, some manufacturers adopt the signal strength algorithm specified by the 802.11 standard, while some manufacturers adopt a signal strength algorithm with self-defined rules based on their own device ecosystems. In this case, the RSSI (Received Signal Strength Indication) calculated by the gateway device in the same way for STAs from different manufacturers through the underlying driver may be incorrect. This is because the underlying driver of a single gateway device has poor compatibility with STAs from different manufacturers and can only calculate an approximate value of the actual RSSI, with a high possibility of a large deviation. Therefore, it is not appropriate to use the underlying driver to calculate the RSSI during the frequent association process of STAs with APs, which is likely to cause STAs to switch APs (Access Points) incorrectly during the roaming process in the current wireless local area network, resulting in users being unable to receive a good signal and having a poor experience. Based on this, the present invention provides a signal strength measurement method, a wireless gateway device, and a readable storage medium. By traversing and calculating multiple preset signal strength algorithms, the signal strength algorithm suitable for the STA that first accesses is matched, and the first signal strength algorithm obtained by the matching is associated with the STA. Thus, during the roaming process of the STA in the current wireless local area network, the first signal strength algorithm can be directly called to calculate the RSSI of the STA. Therefore, the most suitable signal strength algorithm can be called for STAs from different manufacturers to obtain accurate RSSI, avoiding the problem of incorrect RSSI calculation due to poor compatibility during the roaming process.

[0028] The following further elaborates on the embodiments of the present invention with reference to the accompanying drawings.

[0029] As Figure 1 shown, the first aspect of the embodiment of the present invention provides a signal strength measurement method, including:

[0030] S110, obtaining the STA identification field of the station STA accessing the wireless access point AP;

[0031] When a STA roams in the current wireless local area network, it needs to access one of the APs to achieve a stable network connection. Obviously, multiple APs are often set up in the wireless local area network to expand the signal coverage. During the roaming process, the STA selects an AP to access based on the measured RSSI strength, and uploads STA-related information when accessing the AP. For example, the STA uploads the STA identification field to the AP, including the MAC (Media Access Control, physical address) and IP address (Internet Protocol Address) of the STA. The AP knows the information of the currently accessed STA by parsing the data packet, so as to facilitate the subsequent search for the signal strength algorithm.

[0032] S120, search for the signal strength algorithm associated with the STA identification field;

[0033] The reason for being able to search according to the STA identification field uploaded by the STA lies in the uniqueness of the STA identification field (MAC address, or the combination of MAC address and IP address). Based on this, the gateway device can correspond the STA with the signal strength algorithm one by one.

[0034] S130, when the associated signal strength algorithm is found, obtain the RSSI of the STA according to the found signal strength algorithm;

[0035] Step S130 corresponds to the situation where the STA accesses for the non-first time. Since the gateway device has stored the signal strength algorithm corresponding to the STA, the signal strength algorithm corresponding to the STA can be directly called according to the STA identification field uploaded by the STA, so as to obtain the RSSI of the STA.

[0036] S140, when the associated signal strength algorithm cannot be found, obtain the first RSSI of the STA and the received channel power parameter RCPI (Received Signal Strength Indication), match the first signal strength algorithm from the preset signal strength algorithms according to the first RSSI and RCPI, and associate the first signal strength algorithm with the STA identification field.

[0037] Step S140 corresponds to the situation where the STA accesses for the first time. Since the information of the STA accessing for the first time is not saved in the gateway device, the gateway device cannot find the corresponding signal strength algorithm at this time. It is necessary to match the signal strength algorithm for the STA accessing for the first time. The gateway device obtains the first RSSI through the conventional method, and also obtains the received channel power parameter RCPI through the self-measurement method. According to the first RSSI and RCPI, the first signal strength algorithm is matched from the preset signal strength algorithms, and it is associated as the signal strength algorithm suitable for the current STA. Specifically, referring to Figure 2 , the first signal strength algorithm is selected through the following method:

[0038] S210, Substitute the RCPI into the preset n signal strength algorithms respectively to obtain n RSSI[i], where RSSI[i] corresponds to the preset signal strength algorithm one by one, and i is a positive integer not greater than n;

[0039] Pre-store n signal strength algorithms in a memory in advance. To improve the accuracy, the preset n signal strength algorithms include but are not limited to the currently mainstream signal strength algorithms; substitute the calculated RCPI into the n signal strength algorithms respectively, and n signal strength values can be obtained, which are represented by RSSI[i]. The value of i is a positive integer between 1 and n, that is, the result obtained by the i-th signal strength algorithm is RSSI[i];

[0040] S220, Determine the RSSI[i] that is numerically closest to the first RSSI, and determine the preset signal strength algorithm corresponding to RSSI[i] as the first signal strength algorithm.

[0041] Through the above calculation, compare the obtained n RSSI[i] with the first RSSI[i] respectively, select the RSSI[i] that is numerically closest to the first RSSI, and select the signal strength algorithm corresponding to RSSI[i] as the first signal strength algorithm; the first signal strength algorithm selected in this way is considered to be consistent or matched with the signal strength algorithm actually used by the STA. Therefore, the first signal strength algorithm is associated with the STA identification field and saved locally, so that when the STA accesses the AP again, the first signal strength algorithm can be directly called to calculate the RSSI, reducing resource consumption and improving the accuracy of STA roaming access.

[0042] In an embodiment, referring to Figure 3 , when obtaining the STA identification field of the station STA accessing the wireless access point AP, also obtain the power information of the STA; the specific process of obtaining the first RSSI and the received channel power parameter RCPI of the STA in step S140 includes:

[0043] S310. Determine the first RSSI of the STA according to the power information;

[0044] According to the power information, the underlying driver of the gateway device can be used to calculate the RSSI, that is, the RSSI calculation in the conventional way. Although there may be calculation errors, for the STA that accesses for the first time, calculating the first RSSI through the underlying driver and using it as a reference value for signal strength algorithm matching is appropriate.

[0045] S320. Start the self-measurement process of the AP;

[0046] S330. Receive the RCPI reported by the STA;

[0047] In this embodiment, the gateway device obtains the RCPI by starting the self-measurement process. For example, the gateway device performs self-measurement based on the 802.11k protocol to receive the RCPI reported by the STA; refer to Figure 4 , where starting the self-measurement process of the AP specifically includes the following steps:

[0048] S410. Start timing;

[0049] S420. When the timing exceeds the preset time threshold, initiate a self-measurement request.

[0050] The purpose of starting the self-measurement request after timing is that some STAs reject the self-measurement requests sent by the AP in the initial stage of accessing the AP. This time length is usually 20 seconds to 30 seconds. Therefore, in order to be compatible with various STAs to implement RSSI measurement, the gateway device performs internal timing. When the timing exceeds the preset time threshold, a self-measurement request is initiated, which can avoid the situation where the self-measurement request is rejected in the initial stage of the STA accessing the AP.

[0051] In one embodiment, after step S140 selects the first signal strength algorithm, refer to Figure 5 , associate the first signal strength algorithm with the STA identification field, which specifically includes the following steps:

[0052] S510. Obtain the algorithm type of the first signal strength algorithm;

[0053] S520. Save the algorithm type and associate the algorithm type with the STA identification field.

[0054] Each of the preset n signal strength algorithms is set with a corresponding algorithm type. After selecting the first signal strength algorithm, obtain the algorithm type of the first signal strength algorithm and associate it with the STA identification field. In this way, when looking up the STA identification field, the algorithm type can be associated, and then the first signal strength algorithm can be called.

[0055] In one embodiment, refer toFigure 6 , for the case of a non-first-access STA, there are two different situations for calculating the RSSI of the STA. In the first situation, step S130 specifically includes:

[0056] S610, start the self-measurement process of the AP to obtain the received channel power parameter RCPI of the STA;

[0057] S620, obtain the RSSI of the STA according to the found signal strength algorithm and RCPI.

[0058] In this case, the AP for association starts the self-measurement process to obtain RCPI, and calculates the RSSI according to the obtained RCPI and the found signal strength algorithm; it can be understood that since the STA is not accessing for the first time, the STA identification field of the STA is stored in the gateway device. According to the method for the first access described above, the STA has associated the STA identification field with the first signal strength algorithm (i.e., the found signal strength algorithm) when accessing for the first time. Therefore, the associated signal strength algorithm can be directly called during this access to obtain the accurate RSSI.

[0059] In the second situation, referring to Figure 7 , step S130 specifically includes:

[0060] S710, find the RCPI of the STA associated with the signal strength algorithm;

[0061] S720, obtain the RSSI of the STA according to the found signal strength algorithm and RCPI.

[0062] In this case, the AP for association does not start the self-measurement process, but calculates the RSSI according to the RCPI value saved when the STA accessed for the first time. This saved RCPI is obviously obtained when the STA was associated with the STA identification field during the first access. In this way, the RSSI can be calculated directly without starting the self-measurement during this access.

[0063] The following uses an actual example to illustrate the embodiments of the present invention, which specifically includes the following steps:

[0064] Obtain the STA identification field of the station STA accessing the wireless access point AP;

[0065] Find the signal strength algorithm associated with the STA identification field;

[0066] If the associated signal strength algorithm is found, it is determined that the STA is not accessing the AP for the first time;

[0067] Find the received channel power parameter RCPI of the STA associated with the signal strength algorithm;

[0068] Obtain the RSSI of the STA according to the found signal strength algorithm and the RCPI.

[0069] If no associated signal strength algorithm can be found, determine that the STA is accessing the AP for the first time;

[0070] Obtain the power information of the STA, and determine the first RSSI of the STA according to the power information;

[0071] Start timing;

[0072] When the timing exceeds the preset time threshold, initiate a self-measurement request for the AP;

[0073] Receive the RCPI reported by the STA;

[0074] Substitute the RCPI into each of the n preset signal strength algorithms respectively to obtain n RSSI[i], where RSSI[i] corresponds one-to-one to the preset signal strength algorithm, n is a positive integer, and i is a positive integer not greater than n;

[0075] Determine the RSSI[i] that is numerically closest to the first RSSI, and determine the preset signal strength algorithm corresponding to RSSI[i] as the first signal strength algorithm;

[0076] Obtain the algorithm type of the first signal strength algorithm;

[0077] Save the algorithm type and associate the algorithm type with the STA identification field.

[0078] When the STA switches the accessed AP during the roaming process in the wireless local area network, the RSSI is calculated according to the association information uploaded by the STA accessing the AP at this time. If the STA identifier field of the STA can be found in the gateway, it means that the STA is not accessing the current wireless local area network for the first time. At this time, the signal strength algorithm associated with the STA identifier field can be directly called to calculate the RSSI; if the STA identifier field of the STA cannot be found in the gateway, it means that the STA is accessing the current wireless local area network for the first time. At this time, the gateway calculates the first RSSI and RCPI in a conventional manner, and based on a plurality of preset signal strength algorithms, matches a first signal strength algorithm suitable for calculating the RSSI of the STA, and finally associates the first signal strength algorithm with the STA identifier field for calling when the STA accesses the current wireless local area network again; In the embodiment of the present invention, by traversing and calculating a plurality of preset signal strength algorithms to match the signal strength algorithm suitable for the STA accessing for the first time, and associating the matched first signal strength algorithm with the STA, so that during the roaming process of the STA in the current wireless local area network, the first signal strength algorithm can be directly called to calculate the RSSI of the STA. Therefore, for STAs of different manufacturers, the most suitable signal strength algorithm can be called to obtain accurate RSSI, avoiding the problem of incorrect RSSI calculation due to poor compatibility during the roaming process.
