Description

Multi-standard terminal compatible processing method, device and system

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a multi-standard terminal compatible processing method, device and system.

Background

Nowadays, Wireless Local Area Networks (WLANs) based on the 802.11 standard are widely deployed in schools, hospitals, airports and many enterprises to provide high-speed and convenient data services, and on the other hand, chips supporting the 802.11 standard have become indispensable hardware configurations of intelligent terminals (such as mobile phones, tablet computers, notebook computers, etc.). Due to the continuous evolution of the 802.11 standard, a scene of coexistence of terminals of multiple standards will exist for a long time. The current 802.11 standards supported by terminals include 802.11a, 802.11b, 802.11g, 802.11n, and 802.11ac, on one hand, the rates supported by terminals supporting different standards are very different, for example, the highest rate supported by 802.11a/g is 54Mbps, the highest rate supported by 802.11b is 11Mbps, the highest rate supported by 802.11n is 600Mbps, and the highest rate supported by 802.11ac exceeds 1 Gbps. On the other hand, terminals supporting these standards also operate in different frequency bands, 802.11a and 802.11ac operate in a 5G frequency band, 802.11b and 802.11G operate in a 2.4G frequency band, and 802.11n simultaneously supports terminals operating in 2.4G and 5G frequency bands.

Coexistence of terminals supporting multiple standards eventually leads to network throughput degradation for the following reasons: on one hand, the coexistence of Multiple standard terminals can cause the efficiency of an Access Point (AP) to be greatly reduced, and due to a competition mechanism of Carrier Sense Multiple Access (CSMA), a low-speed terminal can occupy a large amount of air interface time and influence the Access of a high-speed terminal, thereby reducing the total throughput of a network. On the other hand, when multiple standard terminals coexist, the AP and the terminals need to transmit a large amount of control signaling in order to reduce the collision probability. For example, in order for a terminal supporting 802.11g and an AP to be compatible with 802.11b, a Request to Send/Clear to Send (RTS/CTS) frame using a Direct Sequence Spread Spectrum (DSSS) modulation scheme needs to be sent. A large amount of control signaling will occupy a large amount of air interface time, resulting in a large reduction in network throughput.

In order to solve the above problems, one method in the prior art is to increase the received signal strength of the low-speed terminal users using 802.11a and 802.11g by using a multi-antenna beamforming technique, so as to increase the sending and receiving rates of the low-speed terminal and improve the throughput of the network; the other is to make the terminals with different rates occupy the same air interface time through dynamic air interface scheduling, or to improve the priority of the high-speed terminal user to access the network, so as to increase the throughput of the network.

However, the above-mentioned techniques do not reduce the overhead of control signaling brought by multi-standard terminal compatibility, and have a limited improvement on network throughput, and in the first technique, hardware upgrade of the AP is required, which increases cost.

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 clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment of the invention is based on a centralized WLAN network, and comprises a terminal user, an AP (Access Controller, hereinafter referred to as AC), wherein the terminal user accesses the network through the AP, the AC manages the AP and all terminal users accessing the WLAN network, and the information is interacted between the AC and the AP through a predefined protocol (CAPWAP, SNMP) and the like.

Fig. 1 is a flowchart of a first embodiment of a multi-standard terminal compatibility processing method according to the present invention, and this embodiment takes an AC as an execution subject for description, as shown in fig. 1, the method of this embodiment may include:

s101, the AC receives terminal user information periodically sent by the AP, and the terminal user information comprises: a terminal user identification ID, a terminal type, a user type, an associated AP and an adjacent AP.

The terminal type refers to whether the terminal user is a high-speed terminal or a low-speed terminal, and the user type refers to whether the terminal user is an edge user or a center user.

Before the AP sends the terminal user information, the AP periodically counts to obtain the terminal user information, and specifically, the AP may obtain a standard type supported by the terminal user by detecting a data modulation mode and a packet header of a data packet sent by the terminal user, or require the terminal user to actively report the standard type supported by the terminal user, and when the standard types supported by the terminal user are multiple, use the standard type supporting the highest rate as the standard type of the terminal user. Then, the AP divides the terminal user into a high-speed terminal and a low-speed terminal according to the working frequency band supported by the standard type of the terminal user, for example, when the 802.11ac terminal and the 802.11n/a terminal coexist, the 802.11ac terminal is the high-speed terminal, and the 802.11n/a terminal is the low-speed terminal; when 802.11n and 802.11a/b/g terminals coexist, the 802.11n terminal is a high-speed terminal; when 802.11b and 802.11g terminals coexist, the 802.11g terminal is a high-speed terminal, and the 802.11b terminal is a low-speed terminal; when 802.11a/ac and 802.11b/g terminals coexist, this situation is treated independently because they operate in different frequency bands.

And then the AP divides the terminal user into a central user and an edge user according to whether the terminal user has an adjacent cell, wherein if the signal intensity of a non-associated cell received by the terminal user exceeds a preset threshold value, the non-associated cell is the adjacent cell of the terminal user, the terminal user with the adjacent cell is the edge user, and the terminal user without the adjacent cell is the central user.

And finally, the AP sends the terminal user information comprising the terminal user Identification (ID), the terminal type, the user type, the associated AP and the adjacent AP to the AC. For example, the end-user information is shown in the following table one:

watch 1

It should be noted here that, because 802.11n supports terminals operating in 2.4G and 5G frequency bands simultaneously, the types of terminals operating in the two frequency bands of a terminal user with a standard type of 802.11n may be different, so when an AP sends terminal user information to an AC, the AP needs to report the types of terminals operating in the two frequency bands of the terminal user with the standard type of 802.11n, respectively.

And S102, the AC classifies the terminal users of each cell according to the terminal user information, and performs working frequency band migration or cell migration on the terminal users supporting the same working frequency band after classification.

Specifically, the AC performs classification processing on the terminal users of each cell according to the working frequency bands supported by the terminal users, and performs corresponding processing for different working frequency bands. When the working frequency band supported by the terminal user can be switched, the AC switches the working frequency band of the terminal user, if the terminal user of 802.11n and the user of 802.11b/G coexist, the user of 802.11n is transferred to the working frequency band of 5G, and if the terminal user of 802.11n and the user of 802.11a/AC coexist, the user of 802.11n is transferred to the working frequency band of 2.4G. Specifically, the terminal user is notified to adjust the working frequency band of the terminal user.

When the working frequency band of the terminal user can not be switched, the following processing is carried out:

and S10, clustering edge users in the terminal users by the AC according to the terminal user information, and dividing the edge users with the same adjacent area AP and the same terminal type in the same cell into the same cluster to obtain cluster users.

And S11, the AC migrates the cluster user to the adjacent cell of the cluster user according to the preset condition.

Specifically, when the cluster user is a low-speed terminal, when the number of central users whose terminal types are high-speed terminals in a cell where the cluster user is located is greater than a preset threshold value, and the number of central users whose terminal types are high-speed terminals in an adjacent cell of the cluster user is less than the preset threshold value, the AC migrates the cluster user to the adjacent cell of the cluster user. Or,

when the cluster user is a high-speed terminal, when the number of central users with the terminal type of the high-speed terminal in the cell where the cluster user is located is smaller than a preset threshold value, and the number of central users with the terminal type of the high-speed terminal in an adjacent cell of the cluster user is larger than the preset threshold value, the AC migrates the cluster user to the adjacent cell of the cluster user.

The setting of the preset threshold value can be determined according to the model evaluation gain, and when the preset threshold value is determined according to the model, whether the gain exists in the migration or not is determined. If there is no model, the threshold can be set to 100%, i.e. the case where gain is determined is migrated, and the case where it is not determined whether there is gain is adjusted is temporarily not.

It should be noted here that, further, the AC may perform iterative operation on the working frequency band migration or cell migration of the terminal user, and when no cluster user needs to perform migration processing, or when the iteration reaches a preset number of times, the iteration is stopped.

Further, the AC performs cell migration on the cluster users according to the cluster user priorities, and the smaller the number of the cluster users, the higher the priority.

Wherein, the AC migrates the cluster user to the neighboring cell of the cluster user, and the specific process may be:

and the AC sends a switching instruction to an associated AP of the cluster user, and the associated AP adjusts radio frequency parameters according to the switching instruction to complete the cell migration of the cluster user, wherein the radio frequency parameters comprise power and an antenna directional diagram. Taking the adjustment of the antenna directional diagram as an example, if a certain cluster of users needs to be switched from the cell a to the cell B, the coverage directional diagram of the cell a can be adjusted, the strength of the cluster of users receiving the AP signal of the cell a is reduced, or the coverage directional diagram of the cell B is adjusted, the strength of the cluster of users receiving the AP signal of the cell B is increased, or both the two are adjusted at the same time, so that the strength of the cluster of users receiving the AP signal of the cell B exceeds the cell a and exceeds the minimum demodulation threshold, and the users can automatically complete the switching and re-associate from the cell a to the cell B.

And after the terminal user migration is finished, the AC analyzes the coexistence condition of each cell, and if a certain cell is a single type of terminal user, the AC sends an instruction to the AP to change the compatible working mode of the AP and stop sending the additional control frame. For cells where different types of terminals coexist, the control frame still needs to be transmitted.

For a network with user migration, the AP needs to adjust an air interface scheduling policy according to the distribution of users. And adjusting the priority of the high-speed terminal according to the proportion of the high-speed terminal. The adjustment strategy may be as follows: when the high-speed terminal increases in proportion, the priority of the high-speed terminal is reduced; otherwise, the priority is improved, and certain fairness is ensured.

In the multi-standard terminal compatibility processing method provided in this embodiment, the AC is used to receive the terminal user information periodically sent by the AP, classify the terminal users of each cell according to the terminal user information, and perform working frequency band migration or cell migration on the terminal users supporting the same working frequency band after classification. Therefore, terminal users supporting the same working frequency band among cells can be migrated to the same cell to work, and extra signaling overhead brought by compatibility is reduced, so that the reduction of throughput brought by the compatibility of the cells with terminals of different standards can be reduced. In addition, the similar terminals can be gathered through multiple iterations, the effect of air interface scheduling is improved, and the throughput of the network is improved.

Fig. 2 is a flowchart of a second embodiment of the multi-standard terminal compatibility processing method of the present invention, and as shown in fig. 2, the method of this embodiment may include:

s201, AP periodically acquires terminal user information, wherein the terminal user information comprises: a terminal user identification ID, a terminal type, a user type, an associated AP and an adjacent AP.

Specifically, the AP may obtain the standard type supported by the terminal user by detecting the data modulation mode and the packet header of the data packet sent by the terminal user, or require the terminal user to actively report the standard type supported by the terminal user, and when the standard types supported by the terminal user are multiple, use the standard type supporting the highest rate as the standard type of the terminal user. Then, the AP divides the terminal user into a high-speed terminal and a low-speed terminal according to the working frequency band supported by the standard type of the terminal user, for example, when the 802.11ac terminal and the 802.11n/a terminal coexist, the 802.11ac terminal is the high-speed terminal, and the 802.11n/a terminal is the low-speed terminal; when 802.11n and 802.11a/b/g terminals coexist, the 802.11n terminal is a high-speed terminal; when 802.11b and 802.11g terminals coexist, the 802.11g terminal is a high-speed terminal, and the 802.11b terminal is a low-speed terminal; when 802.11a/ac and 802.11b/g terminals coexist, this situation is treated independently because they operate in different frequency bands.

And finally, the AP sends the terminal user information comprising the terminal user ID, the terminal type, the user type, the associated AP and the adjacent AP to the AC.

S202, the AP sends the terminal user information to the AC, so that the AC classifies the terminal users of each cell according to the terminal user information, and performs working frequency band migration or cell migration on the terminal users supporting the same working frequency band after classification.

Further, after the AP sends the end user information to the access controller AC, the method further includes:

the AP receives a switching instruction sent by the AC. And the AP adjusts radio frequency parameters according to the switching instruction so as to enable the cluster users to carry out cell migration, wherein the radio frequency parameters comprise power and an antenna directional diagram. Taking the adjustment of the antenna directional diagram as an example, if a certain cluster of users needs to be switched from the cell a to the cell B, the coverage directional diagram of the cell a can be adjusted, the strength of the cluster of users receiving the AP signal of the cell a is reduced, or the coverage directional diagram of the cell B is adjusted, the strength of the cluster of users receiving the AP signal of the cell B is increased, or both the two are adjusted at the same time, so that the strength of the cluster of users receiving the AP signal of the cell B exceeds the cell a and exceeds the minimum demodulation threshold, and the users can automatically complete the switching and re-associate from the cell a to the cell B.

In the multi-standard terminal compatibility processing method provided in this embodiment, the AP periodically obtains the terminal user information, and then sends the terminal user information to the access controller AC, so that the AC performs classification processing on the terminal users of each cell according to the terminal user information, and performs working frequency band migration or cell migration on the terminal users supporting the same working frequency band after the classification processing. Therefore, terminal users supporting the same working frequency band among cells can be migrated to the same cell to work, and extra signaling overhead brought by compatibility is reduced, so that the reduction of throughput brought by the compatibility of the cells with terminals of different standards can be reduced.

The following describes the technical solution of the embodiment of the method shown in fig. 1 and 2 in detail by using a specific embodiment.

Fig. 3 is a flowchart of a third embodiment of a multi-standard terminal compatibility processing method according to the present invention, and as shown in fig. 3, the method of this embodiment may include:

s301, AP periodically acquires the terminal user information, wherein the terminal user information comprises: a terminal user identification ID, a terminal type, a user type, an associated AP and an adjacent AP.

Specifically, the AP may obtain the standard type supported by the terminal user by detecting the data modulation mode and the packet header of the data packet sent by the terminal user, or require the terminal user to actively report the standard type supported by the terminal user, and when the standard types supported by the terminal user are multiple, use the standard type supporting the highest rate as the standard type of the terminal user. And then the AP divides the terminal user into a high-speed terminal and a low-speed terminal according to the working frequency band supported by the standard type of the terminal user. And then the AP divides the terminal user into a central user and an edge user according to whether the terminal user has an adjacent cell, wherein if the signal intensity of a non-associated cell received by the terminal user exceeds a preset threshold value, the non-associated cell is the adjacent cell of the terminal user, the terminal user with the adjacent cell is the edge user, and the terminal user without the adjacent cell is the central user.

And S302, the AC classifies the terminal users of each cell according to the terminal user information.

And S303, when the working frequency band of the terminal user can be switched, the AC switches the working frequency band of the terminal user.

S304, when the working frequency band of the terminal user can not be switched, the AC clusters the edge users in the terminal user according to the terminal user information, and divides the edge users with the same adjacent cell AP and the same terminal type in the same cell into the same cluster to obtain cluster users.

S305, when the cluster user is a low-speed terminal according to a preset condition, when the number of central users with the terminal type of a high-speed terminal in a cell where the cluster user is located is larger than a preset threshold value and the number of central users with the terminal type of a high-speed terminal in an adjacent cell of the cluster user is smaller than the preset threshold value, the AC migrates the cluster user to the adjacent cell of the cluster user.
