Obviously, the described embodiments are only It is a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

The terms "first", "second", "third", "fourth", etc. (if any) in the description and claims of this application and the above-mentioned drawings are used to distinguish similar objects, without having to use To describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein, for example. In addition, the terms "including" and "having" and any variations of them are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those clearly listed. Those steps or units may include other steps or units that are not clearly listed or are inherent to these processes, methods, products, or equipment.

The embodiments of the present application can be applied to the network architecture shown in FIG. 1, which includes a first network device in a first network, a second network device in a second network, and a newly introduced network element, that is, a network cooperative controller , Wherein the first network and the second network are different types of networks, and the first network device and the second network device are connected through a designated interface for collaboratively providing network services.

As an example, the first network may be a cellular network, including analog cellular networks and digital cellular networks. Specifically, the first network device in the first network may be a base station, and the second network may be a wireless local area network (WLAN). ), the second network device in the second network may specifically be a wireless access point (Wireless Access Point, AP), and the AP in the second network is centrally controlled by a wireless controller (Wireless Access Point Controller, AC).

Among them, the digital cellular network can be a second-generation (2Generation, 2G) communication network such as the Global System for Mobile Communication (GSM), or it can be a CDMA2000 based on Code Division Multiple Access (CDMA). , Wideband Code Division Multiple Access, WCDMA or Time Division Synchronous Code Division Multiple Access, TD-SCDMA, and other third-generation (3Generation, 3G) communication networks, or Long Term Evolution (LTE), and other fourth-generation (4Generation, 4G) communication networks , New Radio (NR) and other fifth-generation (5Generation, 5G) communication networks.

In the above example, the designated interface between the first network device and the second network device may specifically be the Xw interface. In addition, the user terminal (User Equipment, UE) may connect to the cellular network through the uu interface, or through the connection with the WLAN AC/AP The interface between u-wlan connects to WLAN and uses the corresponding network service. It should be noted that the above-mentioned interface is an existing interface, that is, an old interface. In actual application, its cells are adaptively modified to be compatible with the network cooperative control method of this application.

Furthermore, due to the introduction of new logical network elements, such as a cellular WLAN cooperative controller, a new interface is created. For example, the interface between the cellular WLAN cooperative controller and the eNB or gNB in the cellular network is X-3GPP. The interface X-WLAN between the WLAN cooperative controller and the WLAN AC/AP, etc.

The cellular WLAN cooperative controller summarizes the information of the cellular network and the WLAN through the above-mentioned interface, and performs service balancing and interference management based on the information. For ease of understanding, exemplified description is given below with the first network being the cellular network and the second network being the WLAN.

Next, from the perspective of the network cooperative controller, the network cooperative control method provided in the embodiment of the present application is exemplified.

Referring to the flowchart of the network cooperative control method shown in FIG. 2, the method includes:

S201: Receive first information reported by a first network device in the first network and/or second information reported by a second network device in the second network.

The first network and the second network are different types of networks, and the first network device in the first network and the second network device in the second network are connected through a designated interface to achieve network convergence, and Coordinate the provision of network services and give full play to the respective advantages of the first network and the second network.

In practical applications, the first network may be a cellular network, and the second network may be a WLAN. In this way, the first network device may be a base station, and the second network device may be an AP. The network cooperative controller is a centralized control point of the upper layer of the first network and the second network. The first network device and the second network device can report their respective information representing the network conditions to the network cooperative controller, and the network cooperative controller Gather the above information and make adjustments to the network side equipment.

Among them, the network status can include the network load status and the network interference status. The network load status includes the number of connected users (that is, the number of user terminals) and the service operation status of the access users. The network interference status includes the interference that can be divided into user terminal measurement and interference The first interference information obtained by the measurement and/or the second interference information obtained by the interference measurement performed by the second network device.

Based on this, the first information reported by the first network device may be the service characteristic of the service currently running by the user terminal, which is determined by the first network device according to the running service condition of the user terminal connected to the first network device. Of course, in some cases, the first information may also include the first interference information reported by the user terminal, and the first interference information represents the interference situation obtained by the interference measurement performed by the user terminal.

The second information reported by the second network device may be the second interference information reported by the second network device, and the second interference information characterizes the interference situation obtained by the interference measurement performed by the second network device.

S202: Determine a control strategy for a target network device connected to the first network device in the second network by using a collaborative algorithm according to the first information and/or the second information.

It can be understood that when the first information includes the service characteristics of the service currently running on the user terminal, the network coordination controller may determine the first network device with a heavier network load based on the service characteristics. If the user terminal under the first network device mainly runs the designated Service type, the specified service type can be any of various service types, then the target network device can be determined from the second network device connected to the first network device, and the target network device can be determined based on the specified service type that is mainly running The working mode is used as a control strategy for the target network device.

In practical applications, service characteristics may include the number of user terminals running various types of services under the first network device. When the number of user terminals running a specified service type under the first network device reaches the first threshold, there are more The user terminal runs the service of the specified service type, that is, the user terminal under the first network device mainly runs the service of the specified service type. At this time, the network coordination controller may connect at least one second network device connected to the first network device Determined as the target network device.

Of course, the service feature can also be the proportion of user terminals running various types of services under the first network device. When the proportion of user terminals running a specified service type under a network device reaches a first threshold, such as 80%, it can be determined The first network device mainly runs services of a specified service type. At this time, the network coordination controller may determine at least one second network device connected to the first network device as the target network device.

Service types include uplink service types and downlink service types. The so-called uplink service type refers to the service type of data flow mainly from the user terminal to the network device, and the so-called downlink service type refers to the service type of the data flow mainly from the network device side to the user terminal side. . The designated service type can be any of the above-mentioned service types. In one example, when most user terminals are running video watching services, it indicates that they mainly run downlink service types of services. In another example, when watching concerts or sports events, more users take photos and Posting the above-mentioned photos on social platforms indicates that the main business operations are upstream business types.

In consideration of load balancing, the network coordination controller may determine the working mode of the target network device according to the service type corresponding to the service with the largest number of user terminals running various types of services or the largest user terminal proportion.

Specifically, if the number of user terminals running uplink service type services is the largest or the proportion of user terminals is the largest, the working mode of the target network device can be set to uplink only (UL Only) mode, that is, the target network device is only in the uplink The business is offloaded to the first network device to reduce the uplink load of the first network device.

In the same way, if the number of user terminals running downlink services is the largest or the proportion of user terminals is the largest, the working mode of the target network device can be set to DownLink Only (DL Only) mode, that is, the target network device is only in the downlink The business offloads the first network device to reduce the downlink load of the first network device.

Of course, in some cases, such as when the number of user terminals running both the uplink service type and the downlink service type are large, the network coordination controller can also set the working mode of the target network device to a hybrid mode, that is, the target network device is targeted for uplink and downlink services. All are diverted.

In the same way, when the number of user terminals running both the uplink service type and the downlink service type is small, the network coordination controller can also set the working mode of the target network device to non-distribution mode, that is, the target network device does not distribute all services. At this time, the connection between the UE and the WLAN can be released.

In some embodiments, the first information further includes the first interference information reported by the user terminal, and the network coordination controller may also use the channel of the interference source in the first interference information and the service set identifier (Service Set Identifier). , SSID) to determine the target network device. Of course, in some cases, the network coordination controller can determine the target network device according to the channel of the interference source and the basic server identifier (Basic Service Set Identifier, BSSID).

Then, the network cooperative controller can determine the control strategy for the target network device. Specifically, the network cooperative controller can determine whether the power of the interference source of the first interference information type is greater than the preset power threshold. If so, it indicates that the interference source has a large interference to the UE. At this time, the network cooperative controller can determine whether the interference is in the data The role in the transmission process determines the control strategy for the interference source. If it is the sender, the power can be adjusted. For example, the power of the interference source can be reduced to reduce the interference of the interference source. If it is the receiver, it is difficult to reduce the power to improve the UE. The interference can release the UE under the interference source.

In specific implementation, the network collaborative controller can determine the role of the interference source in the transmission process based on the user terminal operating service distribution under the interference source in the first interference information. If the distribution indicates that the number of user terminals running uplink services reaches the third Threshold, or if the proportion of user terminals running uplink services reaches the fourth threshold, it indicates that the interference source is mainly the data receiving method. At this time, the network coordination controller determines that the control strategy for the target network device is to release the interference The user terminal under the source.

Of course, if the distribution indicates that the number of user terminals running downlink services reaches the third threshold or the proportion of user terminals running downlink services reaches the fourth threshold, it indicates that the source of interference is mainly the data sender. When the network coordination controller determines the power adjustment amount for the target network device according to the power of the interference source in the first interference information, the control strategy for the target network device includes adjusting the power adjustment amount of the target network device according to the power adjustment amount. Power until the interference is reduced to a preset level.

When determining the power adjustment amount for the target network device, the network cooperative controller may determine the preset ratio of the interference source power as the power adjustment amount for the target network device, and the preset ratio may be set according to actual needs, for example, Set to 5%, 10%, etc. For example, when the power of the target network device is 100 milliwatts (mW), the power adjustment amount can be set to 10% of 100 mW, that is, 10 mW.

The preset level can be set according to actual needs. In one example, the preset level can be that the interference is zero, that is, no interference is generated.

In this embodiment, the second information includes the second interference information reported by the second network device. Correspondingly, the network coordination controller may determine according to the channel and service set identifier of the interference source in the second interference information The target network device then determines a control strategy for the target network device in the second network.

Similar to determining the control strategy for the target network device based on the first information, the network cooperative controller can first determine whether the power of the interference source in the second interference information is greater than the preset power threshold, and if so, further based on the interference source in the data transmission process The role of determining the control strategy for the interference source.

Specifically, if the distribution of user terminal operating services under the interference source in the second interference information indicates that the number of user terminals running uplink services reaches the fifth threshold, or the proportion of user terminals running uplink services reaches the sixth threshold, then It is determined that the control strategy for the target network device is to release the user terminal under the interference source.

Of course, if the priority of the user terminal operating service under the second network device that reports the second interference information is higher than the priority of the user terminal operating service under the interference source, for example, the UE under the second network device mainly runs a call service , And the UE under the interference source mainly runs the video playback service. Considering that the call service has a higher priority than the video playback service, the network coordination controller can determine that the control strategy for the target network device is to release the user under the interference source The terminal, in this way, can guarantee the needs of users with higher priority.

Among them, the priority of running the business can be set according to actual needs, for example, it can be set according to the real-time requirements of the business and/or the added value brought to the operator, and the network cooperative controller can give priority to guaranteeing higher real-time requirements. Business needs, and business needs that bring high added value to operators.

If the distribution of user terminal services under the interference source in the second interference information indicates that the number of user terminals running downlink-type services reaches the fifth threshold, or the proportion of user terminals running downlink-type services reaches the sixth threshold, It indicates that the interference source is mainly the data sender, and the network cooperative controller can determine the power adjustment amount for the target network device according to the power of the interference source in the second interference information, and determine the control for the target network device The strategy includes adjusting the power of the target network device according to the power adjustment amount until the interference is reduced to a preset level.

It should be noted that, for the first interference information, the third and fourth thresholds used to determine the data sender and the third and fourth thresholds used to determine the data receiver may be the same or different, depending on Set according to actual needs. Similarly, for the second interference information, the fifth and sixth thresholds used to determine the data sender and the fifth and sixth thresholds used to determine the data receiver can be the same or different, which can be based on actual needs. And set.

S203: Adjust the working state of the target network device according to the control strategy.

Specifically, when the control strategy is to adjust the working mode, the network coordination controller may send the working mode of the target network device to the first network device, and instruct the first network device to send the user terminal to the user terminal. The working mode of the target network device, so that the user terminal resets the offload mode of the target network device.

When the control strategy is to adjust the power of the target device according to the power adjustment amount until the interference is reduced to a preset level, the network coordination controller may send the power adjustment amount to the target network device, indicating the target The network device adjusts the power according to the power adjustment amount.

When the control strategy is to release the user terminal under the target network device, the control strategy is sent to the first network device to instruct the target network device to send instruction information to the user terminal to instruct the user terminal to release Network connection with the target network device.

It can be seen from the above that the embodiment of the present application provides a network cooperative control method. When the first network and the second network are merged, a new logical network element, that is, a network cooperative controller, is introduced in the upper layer of the first network and the second network. It can receive the first information reported by the first network device and/or the second information reported by the second network device, and determine the control strategy for the target network device based on the first information and/or second information reported by the network device using a collaborative algorithm , And adjust the working status of the network device based on the control strategy, such as adjusting the uplink and downlink mode of the network device or the power of a certain network device, which can balance the network side load, reduce network interference, and have high availability, meeting user needs.

In order to facilitate the understanding of the technical solution of the present application, the following will exemplify the network cooperative control method in conjunction with the sequence diagram.

Referring to the sequence diagram of the network cooperative control method shown in Figure 3, as shown in Figure 3, the UE completes the UE capability negotiation, air interface measurement, and WLAN establishment of the cellular and WLAN in advance, and then performs the following steps:

1. The UE reports the user's business characteristics on the uu port;

Specifically, when the UE is watching a video, the reported service feature is a downlink service, and when the UE is conducting a live video broadcast, the reported service feature is an uplink service;

2. The UE reports the first interference information on the uu port. The first interference information includes the channel, SSID/BSSID, signal strength and other information of the interference source obtained by the UE in the interference measurement;

3. The cellular eNB/gNB summarizes the service feature information of multiple UEs under the network element, the WLAN information associated with the UE, and the first interference information and sends it to the "cellular WLAN cooperative controller";

4. The WLAN AC/AP performs interference measurement to obtain the second interference information, and sends the second interference information to the "cellular WLAN cooperative controller";

5. "Cellular WLAN collaborative controller" uses a collaborative algorithm to determine a control strategy for the target network device based on the aggregated service feature information, UE-related WLAN information, first interference information, and second interference information;

Specifically, the network coordination controller performs optimization calculations such as WLAN AP DL/UL working mode, AP channel/power configuration, and WLAN release based on the information summarized by multiple cellular eNB/gNB and WLAN AC/AP;

6. "Cellular WLAN collaborative controller" outputs through the aforementioned collaborative algorithm: WLAN AP DL/UL working mode, release of WLAN and other information are sent to the cellular eNB/gNB;

7. The cellular eNB/gNB generates the configuration information of the UE and sends it to the UE. If the AP works in DL only mode, reset the data offload mode of the UE under this AP to uplink no offload; if the AP working mode is UL only, then reset Suppose the offload algorithm under this AP is no offload for downlink; if a UE does not offload for uplink and downlink, the WLAN connection can be released;

8. The "Cellular WLAN Collaborative Controller" outputs through the aforementioned collaborative algorithm: power increase/decrease/channel reconfiguration/frequency range reset of an AP, etc., then the WLAN AC/AP performs this operation.

In the above-mentioned embodiment, the order of steps 1 and 2 can be arbitrary, for example, it can be performed at the same time or one after another. Similarly, the order of steps 3 and 4 and the order of steps 6 and 8 can also be arbitrary, such as Point to the above steps 3 and 4 at the same time, and perform the above steps 6 and 8 at the same time.

In practical applications, the network cooperative controller can also implement network cooperative control only based on service characteristics or only based on interference information, which will be described in detail below in conjunction with a sequence diagram.

Referring to the sequence diagram of the network cooperative control method shown in FIG. 4, in this method, the UE has completed UE capability negotiation, air interface measurement, and WLAN connection establishment of the cellular and WLAN. The method includes:
