Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 is a schematic flow chart of a signal quality optimization method provided by the present invention, as shown in fig. 1, the method is applied to a virtual home gateway unit, and includes the following steps:
and 100, acquiring a local site information table of each home gateway unit in the fiber-to-the-home virtual domain, and summarizing the local site information table to obtain a domain site information table of the fiber-to-the-home virtual domain.
And 101, calculating the domain overall throughput score of the fiber-to-the-home virtual domain based on the domain site information table.
Step 102, adjusting the channel and/or bandwidth of the home gateway unit based on the overall throughput score in the domain of the fiber-to-the-home virtual domain.
The virtual home gateway unit is generated by the optical line terminal in the process of creating the optical fiber home virtual domain; the intra-domain overall throughput score is used to represent the intra-domain overall throughput of the fiber-to-the-home virtual domain.
Specifically, in the embodiment of the invention, in the process of creating the FTTR virtual domain, the optical line terminal (Optical Line Terminal, OLT) creates a virtual home gateway unit (Home Gateway Unit, HGU) for the FTTR virtual domain, where the virtual home gateway unit can act as a proxy for all HGUs in the FTTR virtual domain.
All HGUs within the FTTR virtual domain each maintain a local Station (STA) information table locally, which may include a terminal identification (e.g., may be represented by a media access control (Media Access Control, MAC) address) and a received signal strength indication (Received Signal Strength Indicator, RSSI) of the STA to which the HGU is connected.
The HGUs in the FTTR virtual domain may send respective local site information tables to the virtual home gateway unit at regular time, and after the virtual home gateway unit obtains the local site information tables of the HGUs, the domain site information tables of the entire FTTR virtual domain may be obtained by summarizing.
After obtaining the domain site information table of the whole FTTR virtual domain, the virtual home gateway unit may calculate the domain overall throughput score of the whole FTTR virtual domain based on the domain site information table.
In some embodiments, the domain site information table, the channels of each HGU, the bandwidth of each HGU, the transmit power of each HGU, and statistics of error alarms (noise) of the current channel of each HGU, noise intensity, user datagram statistics, and the like may be used as indicators to score the overall throughput in the domain of the overall FTTR virtual domain.
The method for scoring the throughput condition in the embodiment of the invention is not limited, for example, the indexes can be weighted to calculate the overall throughput score in the domain, and the higher the obtained overall throughput score in the domain is, the better the throughput condition of the whole FTTR virtual domain is, and the lower the overall throughput score in the domain is, the worse the throughput condition of the whole FTTR virtual domain is.
It will be appreciated that the HGU in the FTTR virtual domain periodically sends the respective local site information table to the virtual home gateway unit, which may update the domain site information table in real time and calculate the domain overall throughput score for the entire FTTR virtual domain in real time.
In the case where the intra-domain STA in the FTTR virtual domain changes, the intra-domain overall throughput score calculated in real time by the virtual home gateway unit also changes. Therefore, the virtual home gateway unit can adjust the channel of the intra-domain HGU according to the change condition of the overall throughput score in the domain; or, adjusting the bandwidth of the HGU in the domain; or, the channel and the bandwidth of the intra-domain HGU are adjusted.
According to the signal quality optimization method provided by the invention, the optical fiber home virtual domain is created through the optical fiber router terminal, the virtual home gateway units are generated, the local site information tables of all the home gateway units are acquired and summarized by the virtual home gateway units, the intra-domain overall throughput score is calculated according to the summarized domain site information tables, and the channel and/or bandwidth of the home gateway units are adjusted according to the intra-domain overall throughput score, so that the adjusted intra-domain overall throughput score is higher than the intra-domain overall throughput score before adjustment, and the optimization of the overall signal quality of the wireless terminal in the FTTR domain can be realized.
Optionally, the method further comprises:
sending a virtual domain access point discovery message to each home gateway unit, wherein the virtual domain access point discovery message is used for triggering each home gateway unit to request wireless parameter configuration;
Receiving a wireless parameter configuration request message sent by each home gateway unit;
and based on the wireless parameter configuration request message, the wireless parameter configuration of the optical line terminal to each home gateway unit is sent to each home gateway unit.
Specifically, in the embodiment of the present invention, the virtual home gateway unit may further obtain the wireless parameter configuration of the HGU in the domain from the OLT and issue the configuration to each HGU.
The virtual home gateway unit may send a virtual domain access point discovery (Virtual Area AP Discovery, VAAPD) message to each HGU, the virtual domain access point discovery message being used to trigger each HGU to request the virtual home gateway unit for the wireless parameter configuration.
After receiving the radio parameter configuration request message sent by each HGU, the virtual home gateway unit may send the radio parameter configuration obtained from the OLT to each HGU.
In some embodiments, the maximum bandwidth supported by each HGU may be used as the initial configuration of the bandwidth of each HGU, for example, the initial value of the bandwidth of each HGU is set to 160MHz if the maximum supported bandwidth of each HGU is 160MHz, the initial transmit power of each HGU may be set to 100%, and the channel of each HGU is set to be automatic.
In some embodiments, after the wireless parameter configuration is locally completed, each HGU may reply to the virtual home gateway unit with the respective wireless parameter configuration (such as bandwidth, transmit power, and channel parameters).
Optionally, adjusting the channel and/or bandwidth of the home gateway unit based on the intra-domain overall throughput score of the fiber-to-the-home virtual domain includes:
under the condition that the overall throughput score in the domain is increased, determining a first home gateway unit, wherein the first home gateway unit is the home gateway unit with the largest throughput score increase in the home gateway units;
the bandwidth of the first home gateway unit is increased.
Specifically, in the case that the overall throughput score in the domain increases, the virtual home gateway unit may first determine the increase amount of the throughput score in all the HGUs, and then determine, according to the increase amount of the throughput score of each HGU, the HGU with the largest increase amount of the throughput score in all the HGUs, that is, the first home gateway unit in the embodiment of the present invention.
The throughput score of a single HGU may be calculated based on a local site information table of the HGU, and the process is similar to the process of scoring the overall throughput in the domain of the overall FTTR virtual domain described above, which is not described herein.
The throughput score of the first home gateway unit increases the most, indicating that the variation in throughput situation of the first home gateway unit is optimal. If the bandwidth of the first home gateway unit does not reach the maximum bandwidth, the throughput score of the first home gateway unit can be continuously increased by increasing the bandwidth of the first home gateway unit, so that the optimization of the overall signal quality of the intra-domain wireless terminal is realized.
It should be noted that, the method of increasing the bandwidth in the embodiment of the present invention is not limited, and may be, for example, increasing the bandwidth by a fixed value (for example, increasing the bandwidth by 10 MHz) or increasing the bandwidth by an original fixed multiple (setting the bandwidth to be 2 times as much as the original), etc.
For example, the determined bandwidth of the first home gateway unit is 80MHz, the maximum bandwidth is 160MHz, and the bandwidth of the first home gateway unit may be set to 160MHz.
Optionally, adjusting the channel and/or bandwidth of the home gateway unit based on the intra-domain overall throughput score of the fiber-to-the-home virtual domain includes:
under the condition that the overall throughput score in the domain is reduced, determining a second home gateway unit, wherein the second home gateway unit is the home gateway unit with the largest throughput score reduction in the home gateway units;
selecting any one of channels which are idle than the current channel for the second home gateway unit, setting the bandwidth of the second home gateway unit as the maximum value, and recalculating the intra-domain overall throughput score of the fiber-to-the-home virtual domain;
reducing the bandwidth of the second home gateway unit and recalculating the intra-domain overall throughput score under the condition that the recalculated intra-domain overall throughput score does not reach the set condition; and repeating the steps of reducing the bandwidth of the second home gateway unit and recalculating the intra-domain overall throughput score until the recalculated intra-domain overall throughput score reaches the set condition.
Specifically, in the case that the overall throughput score in the domain decreases, the virtual home gateway unit may first determine the decrease amount of the throughput score in all the HGUs, and then determine, according to the decrease amount of the throughput score of each HGU, the HGU with the largest decrease amount of the throughput score in all the HGUs, that is, the second home gateway unit in the embodiment of the present invention.
The throughput score of the second home gateway unit is most reduced, indicating that the variation in throughput of the second home gateway unit is worst. The optimization of the overall signal quality of the wireless terminal within the domain may be achieved by attempting to increase the throughput score of the second home gateway unit by changing the channel and bandwidth of the second home gateway unit.
The virtual home gateway unit may first select any one of channels that is more idle than the current channel for the second home gateway unit, and recalculate the intra-domain overall throughput score of the fiber-to-home virtual domain after setting the bandwidth of the second home gateway unit to a maximum value.
Then, the virtual home gateway unit may determine whether the recalculated intra-domain overall throughput score reaches a set condition. The setting condition may be set according to the actual situation, for example, the setting condition is that the increment value of the overall throughput score in the domain after recalculation is larger than the set threshold value, or the setting condition is that the overall throughput score in the domain after recalculation is larger than the set threshold value, or the like.
And under the condition that the recalculated intra-domain overall throughput score reaches the set termination condition, the condition that the adjusted intra-domain overall throughput is optimized is better. And under the condition that the recalculated intra-domain overall throughput score does not reach the set condition, the virtual home gateway unit can reduce the bandwidth of the second home gateway unit, recalculate the intra-domain overall throughput score, and repeatedly reduce the bandwidth of the second home gateway unit and recalculate the intra-domain overall throughput score until the recalculated intra-domain overall throughput score reaches the set condition.
It should be noted that, the method of reducing the bandwidth in the embodiment of the present invention is not limited, and may be, for example, reducing the bandwidth by a fixed value (for example, reducing the bandwidth by 10 MHz) or reducing the bandwidth proportionally (setting the bandwidth to be 1/2 of the original bandwidth).
For example, the maximum bandwidth of the second home gateway unit is 160MHz, the bandwidth of the second home gateway unit may be initially set to 160MHz, and if the set condition is not reached, the bandwidth of the second home gateway unit may be set to 80MHz, and so on.
Optionally, adjusting the channel and/or bandwidth of the home gateway unit based on the intra-domain overall throughput score of the fiber-to-the-home virtual domain includes:
And adjusting the channel and/or bandwidth of the home gateway unit based on the overall throughput score in the domain of the fiber-to-the-home virtual domain and the number of the home gateway units.
In particular, in the case where the number of HGUs in the FTTR domain varies, the overall throughput in the domain also needs to be optimized.
In this case, the virtual home gateway unit may adjust the channel of the in-domain HGU based on the in-domain overall throughput score of the fiber-to-the-home virtual domain and the number of home gateway units; or, adjusting the bandwidth of the HGU in the domain; or, the channel and the bandwidth of the intra-domain HGU are adjusted.
Optionally, adjusting the channel and/or bandwidth of the home gateway unit based on the domain overall throughput score of the fiber-to-the-home virtual domain and the number of home gateway units includes:
determining a third home gateway unit under the condition that the number of the home gateway units is increased, wherein the third home gateway unit is the home gateway unit with the largest throughput score reduction amount in the increased number of the home gateway units;
selecting any one of channels which are idle than the current channel for the third home gateway unit, setting the bandwidth of the third home gateway unit as the maximum value, and recalculating the intra-domain overall throughput score of the fiber-to-the-home virtual domain;
Reducing the bandwidth of the third home gateway unit and recalculating the intra-domain overall throughput score under the condition that the recalculated intra-domain overall throughput score does not reach the set condition; repeating the steps of reducing the bandwidth of the third home gateway unit and recalculating the intra-domain overall throughput score until the recalculated intra-domain overall throughput score reaches the set condition.
Specifically, in the case that the number of HGUs in the domain increases, the virtual home gateway unit may first determine the reduction of the throughput score in the HGUs with the increased number (that is, the existing HGUs), and then determine the HGU with the largest reduction of the throughput score in the existing HGUs according to the reduction of the throughput score of each HGU, that is, the third home gateway unit in the embodiment of the present invention.
The throughput score of the third home gateway unit is most reduced, indicating that the variation in throughput of the third home gateway unit is worst. The optimization of the overall signal quality of the wireless terminal within the domain can be achieved by attempting to increase the throughput score of the third home gateway element by changing the channel and bandwidth of the third home gateway element.
The virtual home gateway unit may first select any one of channels that is more idle than the current channel for the third home gateway unit, and recalculate the intra-domain overall throughput score of the fiber-to-home virtual domain after setting the bandwidth of the third home gateway unit to a maximum value.
Then, the virtual home gateway unit may determine whether the recalculated intra-domain overall throughput score reaches a set condition. The setting condition may be set according to the actual situation, for example, the setting condition is that the increment value of the overall throughput score in the domain after recalculation is larger than the set threshold value, or the setting condition is that the overall throughput score in the domain after recalculation is larger than the set threshold value, or the like.
And under the condition that the recalculated intra-domain overall throughput score reaches the set termination condition, the condition that the adjusted intra-domain overall throughput is optimized is better. And in the case that the recalculated domain global throughput score does not reach the set condition, the virtual home gateway unit may reduce the bandwidth of the third home gateway unit, recalculate the domain global throughput score, and repeat the steps of reducing the bandwidth of the third home gateway unit and recalculate the domain global throughput score until the recalculated domain global throughput score reaches the set condition.
It should be noted that, the method of reducing the bandwidth in the embodiment of the present invention is not limited, and may be, for example, reducing the bandwidth by a fixed value (for example, reducing the bandwidth by 10 MHz) or reducing the bandwidth proportionally (setting the bandwidth to be 1/2 of the original bandwidth).
For example, the maximum bandwidth of the third home gateway unit is 160MHz, the bandwidth of the third home gateway unit may be initially set to 160MHz, and if the set condition is not reached, the bandwidth of the third home gateway unit may be set to 80MHz, and so on.
Optionally, adjusting the channel and/or bandwidth of the home gateway unit based on the domain overall throughput score of the fiber-to-the-home virtual domain and the number of home gateway units includes:
determining a fourth home gateway unit under the condition that the number of the home gateway units is reduced, wherein the fourth home gateway unit is the home gateway unit with the largest throughput score increment in the reduced number of the home gateway units;
and increasing the bandwidth of the fourth home gateway unit.
Specifically, in the case that the number of HGUs in the domain is reduced, the virtual home gateway unit may first determine an increase in throughput score in the reduced number of HGUs (that is, existing HGUs), and then determine, according to the increase in throughput score of each HGU, the HGU with the largest increase in throughput score in the existing HGU, that is, the fourth home gateway unit in the embodiment of the present invention.
The throughput score of the fourth home gateway unit increases the most, indicating that the change in throughput situation of the fourth home gateway unit is optimal. If the bandwidth of the fourth home gateway unit does not reach the maximum bandwidth, the throughput score of the fourth home gateway unit can be continuously increased by increasing the bandwidth of the fourth home gateway unit, so that the optimization of the overall signal quality of the intra-domain wireless terminal is realized.
It should be noted that, the method of increasing the bandwidth in the embodiment of the present invention is not limited, and may be, for example, increasing the bandwidth by a fixed value (for example, increasing the bandwidth by 10 MHz) or increasing the bandwidth by an original fixed multiple (setting the bandwidth to be 2 times as much as the original), etc.
For example, the determined bandwidth of the fourth home gateway unit is 80MHz, the maximum bandwidth is 160MHz, and the bandwidth of the fourth home gateway unit may be set to 160MHz.
The signal quality optimization method provided by the invention is further explained below through embodiments in specific application scenarios.
When the OLT creates an FTTR virtual domain, a Virtual HGU (VHGU) is created for the domain, and the VHGU acts as a proxy for all HGUs (APs) in the domain, which has the following functions: and obtaining the wireless parameter configuration of the intra-domain HGU from the OLT, and transmitting the wireless parameter configuration to each intra-domain HGU (AP), and dynamically adjusting wireless related parameters including channels and bandwidths for the intra-domain HGU (AP). The main process is as follows:
1. after the VHGU is created, a virtual domain AP discovery (Virtual Area AP Discovery, VAAPD) message is sent to all HGUs (APs) in the domain at regular time, and all HGUs in the domain respond to the VAAP message and request wireless parameter configuration from the VHGU. And the VHGU sends the wireless parameter configuration sent by the OLT to the intra-domain HGU to each HGU. For the wireless parameters, the VHGU selects the maximum bandwidth supported by the HGU (AP) in the domain as the initial configuration of the bandwidth, for example, the maximum supported bandwidth of the HGU (AP) in the domain is 160MHz, the initial value of the bandwidth is 160MHz, the transmission power is initially set to 100%, and the channel is set to be automatic. After the HGU in the domain completes configuration locally, its bandwidth, transmitting power and channel parameters are returned to VHGU.
2. Each in-domain HGU maintains a local STA information table locally, comprising the terminal identification (MAC address) and RSSI of the accessed STA, and each in-domain HGU sends the local STA information table to the VHGU at regular time. The VHGU gathers the local STA information table of each HGU in the domain into a domain STA information table, and the VHGU scores the current whole throughput condition of the domain according to the domain STA information table, the channel, the bandwidth and the transmitting power of each HGU, the error alarm (noise) statistical value, the noise intensity and the user data message statistical value of the current channel of each HGU and records the current whole throughput condition of the domain. The greater the score, the better the intra-domain throughput.
3. As STAs within a domain increase or decrease, the domain throughput score of the VHGU record may change:
3.1, when the intra-domain throughput score decreases without intervention of the VHGU, indicating that the intra-domain throughput condition is poor, finding the HGU with the largest decrease in intra-domain HGU throughput score.
Firstly, a relatively idle channel is reselected for the channel, the bandwidth is set to be the maximum, then the domain throughput value is recalculated, if the domain throughput value is not improved by 3 minutes to the expected optimized value, the bandwidth of the HGU (AP) is adjusted to be one half of the current bandwidth until the channel of the HGU (AP) does not need to be readjusted and the bandwidth is adjusted to be the minimum.
3.2, increasing the intra-domain throughput score VHGU without intervention, indicating that the intra-domain throughput condition is good, and finding the HGU with the most increased intra-domain HGU throughput score at the moment:
the corresponding HGU (AP) width is set to twice the current bandwidth until it is set to a maximum value (e.g., 160MHz or 80 MHz).
4. If there is a decrease in HGU (AP) in the domain, step 3.2 is repeated.
5. If there is a new HGU (AP) in the domain, repeating the step 3.1.
