Detailed Description

The embodiment of the application provides a network cooperative control method, which is used for solving the problems that the usability is poor and the user requirements are difficult to meet due to the fact that the network side load and the interference condition are not considered in the existing network fusion method.

In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.

The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the drawings described above, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The embodiment of the present application is applicable to a network architecture as shown in fig. 1, where the network architecture 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 coordination controller, where 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 providing network services in coordination.

As an example, the first Network may be a cellular Network, and includes an analog cellular Network and a digital cellular Network, where the first Network device in the first Network may specifically be a base station, the second Network may specifically be a Wireless Local Area Network (WLAN), the second Network device in the second Network may specifically be a Wireless Access Point (AP), and the AP in the second Network is centrally controlled by a Wireless Access Point Controller (AC).

The digital cellular network may be a second Generation (2G) communication network such as a Global System for mobile communication (GSM), a third Generation (3G) communication network such as CDMA2000, Wideband Code Division Multiple Access (WCDMA) or time Division synchronous Code Division Multiple Access (TD-SCDMA) based on Code Division Multiple Access (CDMA), a fourth Generation (4G) communication network such as Long Term Evolution (LTE), and a fifth Generation (5G) communication network such as New Radio, NR).

In the above example, the specified interface between the first network device and the second network device may specifically be an Xw interface, and furthermore, the User terminal (UE) may connect to the cellular network through a uu interface, or connect to the WLAN through an interface u-WLAN between the UE and the WLAN AC/AP to use the corresponding network service. It should be noted that the above-mentioned interface is an existing interface, i.e. an old interface, and in actual application, the cell of the interface is adaptively modified so as to be compatible with the network cooperative control method of the present application.

Further, due to the introduction of a new logical network element, which may be for example a cellular WLAN coordination controller, new interfaces are created, e.g. interface X-3GPP between the cellular WLAN coordination controller and the eNB or the gNB in the cellular network, interface X-WLAN between the cellular WLAN coordination controller and the WLAN AC/AP, etc.

The cellular WLAN cooperative controller collects the information of the cellular network and the WLAN through the interface, and performs service equalization and interference management according to the information. For ease of understanding, the first network is hereinafter exemplified as a cellular network and the second network is exemplified as a WLAN.

Next, a network coordination control method provided in the embodiment of the present application is exemplarily described from the perspective of a network coordination controller.

Referring to a flowchart of a network cooperation control method shown in fig. 2, the method includes:

s201: receiving first information reported by a first network device in a first network and/or second information reported by a second network device in a second network.

The first network and the second network are different types of networks, and the first network equipment in the first network and the second network equipment in the second network are connected through a designated interface, so that network convergence is realized, network services are cooperatively provided, and the respective advantages of the first network and the second network are fully exerted.

In practice, the first network may be a cellular network and the second network may be a WLAN, and thus the first network device may be a base station and the second network device may be an AP. The network coordination controller is a centralized control point on the upper layers of the first network and the second network, the first network device and the second network device can report information representing network conditions to the network coordination controller, and the network coordination controller aggregates the information to adjust the network side device.

The network condition may include a network load condition and a network interference condition, where the network load condition includes the number of users (i.e., the number of user terminals) accessing and a service operation condition of the users accessing, and the network interference condition includes first interference information obtained by performing interference measurement by a user terminal and/or second interference information obtained by performing interference measurement by a second network device.

Based on this, the first information reported by the first network device may be a service characteristic of a currently running service of the user terminal, which is determined by the first network device according to a running service condition of the user terminal accessing the first network device. Certainly, in some cases, the first information may further include first interference information reported by the ue, where the first interference information represents an interference condition obtained by performing interference measurement by the ue.

The second information reported by the second network device may be second interference information reported by the second network device, where the second interference information represents an interference situation obtained by the second network device performing interference measurement.

S202: and determining a control strategy for a target network device connected with the first network device in the second network by utilizing a cooperative algorithm according to the first information and/or the second information.

It can be understood that, when the first information includes a service feature of a service currently operated by the user terminal, the network coordination controller may determine, based on the service feature, a first network device with a heavier network load, and if the user terminal under the first network device mainly operates a specified service type, which may be any one of the service types, the network coordination controller may determine a target network device from a second network device connected to the first network device, determine a working mode of the target network device based on the specified service type that mainly operates, and use the working mode as a control policy for the target network device.

In practical application, the service characteristics may include the number of user terminals running various types of services under the first network device, and when the number of user terminals running specified service types under the first network device reaches a first threshold, it is characterized that more user terminals run services of specified service types, that is, the user terminals under the first network device mainly run services of specified service types, and at this time, the network coordination controller may determine at least one second network device connected to the first network device as a target network device.

Of course, the service feature may also be a user terminal occupation ratio of each type of service operated by the first network device, and when the user terminal occupation ratio of the specified service type operated by the first network device reaches a first threshold, for example, 80%, it may be determined that the service of the specified service type is mainly operated by the first network device, and 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.

The service types include an uplink service type and a downlink service type, the uplink service type refers to a service type in which a data stream mainly flows from a user terminal to network equipment, and the downlink service type refers to a service type in which a data stream mainly flows from a network equipment side to a user terminal side. The specified traffic type may be any of the traffic types described above. In one example, when a majority of user terminals run a service for watching videos, it indicates that a service of a downlink service type is mainly run, and in another example, when a lot of users take photos and publish the photos on a social platform, it indicates that a service of an uplink service type is mainly run.

In consideration of load balancing, the network coordination controller may determine the operating mode of the target network device according to the service type corresponding to the service in which the number of the user terminals operating each type of service is the largest or the ratio of the user terminals is the largest.

Specifically, if the number of the user terminals running the UpLink service type service is the largest or the percentage of the user terminals is the largest, the operating mode of the target network device may be set to an UpLink Only offload (ULOnly) mode, that is, the target network device Only offloads the first network device in the UpLink service, so as to reduce the UpLink load of the first network device.

Similarly, if the number of the user terminals running the DownLink service type service is the largest or the percentage of the user terminals is the largest, the operating mode of the target network device may be set to a DownLink Only offload (DLOnly) mode, that is, the target network device Only offloads the first network device in the DownLink service, so as to reduce the DownLink load of the first network device.

Certainly, in some cases, for example, when the number of the user terminals running the uplink service type and the downlink service type is large, the network coordination controller may further set the working mode of the target network device to the hybrid mode, that is, the target network device performs the offloading for both the uplink service and the downlink service.

Similarly, when the number of the user terminals operating the uplink service type and the downlink service type is small, the network coordination controller may set the working mode of the target network device to be the non-shunting mode, that is, the target network device does not shunt for all services, and at this time, the connection between the UE and the WLAN may be released.

In some embodiments, the first information further includes first interference information reported by the ue, and the network coordination controller may further determine the target network device according to a channel and a Service Set Identifier (SSID) of an interference source in the first interference information, and in some cases, the network coordination controller may determine the target network device according to a channel and a base server Identifier (BSSID) of the interference source.

The network coordination controller may then determine a control policy for the target network device. Specifically, the network coordination controller may determine whether the power of the interference source of the first interference information is greater than a preset power threshold, and if so, it indicates that the interference source has greater interference to the UE.

In a specific implementation, the network coordination controller may determine a role of the interference source in the transmission process based on a service distribution condition of the user terminal running under the interference source in the first interference information, and if the distribution condition indicates that the number of the user terminals running the uplink type service reaches a third threshold, or the percentage of the user terminals running the uplink type service reaches a fourth threshold, it indicates that the interference source is mainly a data receiving method, and at this time, the network coordination controller determines that the control policy for the target network device is to release the user terminal under the interference source.

Of course, if the distribution condition indicates that the number of the user terminals running the downlink type service reaches the third threshold or the percentage of the user terminals running the downlink type service reaches the fourth threshold, it indicates that the interference source is mainly a data sender, at this time, the network coordination controller determines a power adjustment amount for the target network device according to the power of the interference source in the first interference information, and the control strategy for the target network device includes adjusting the power of the target network device according to the power adjustment amount until the interference is reduced to a preset degree.

When determining the power adjustment amount for the target network device, the network coordination controller may determine a preset proportion of the interference source power as the power adjustment amount for the target network device, where the preset proportion may be set according to an actual requirement, for example, may be set to 5%, 10%, and so on. For example, when the power of the target network device is 100 milliwatts (mW), the power adjustment amount may be set to 10% of 100m W, i.e., 10 mW.

The preset degree may be set according to actual needs, and in one example, the preset degree may be that the interference is 0, that is, no interference is generated.

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

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

Specifically, if the distribution of the service running of the user terminal under the interference source in the second interference information indicates that the number of the user terminals running the uplink type service reaches a fifth threshold, or the percentage of the user terminals running the uplink type service reaches a sixth threshold, the control policy for the target network device is determined to be to release the user terminal under the interference source.

Of course, if the priority of the service run by the user terminal under the second network device reporting the second interference information is higher than the priority of the service run by the user terminal 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 a video playing service, the network coordination controller may determine that the control policy for the target network device is to release the user terminal under the interference source in consideration of the fact that the priority of the call service is higher than the video playing service, so that the user requirement with higher priority can be ensured.

The priority of the operation service can be set according to actual needs, for example, the priority can be set according to the requirement of the service on real-time performance and/or the added value brought to the operator, and the network coordination controller can preferentially guarantee the service requirement with higher requirement on real-time performance and the service requirement with high added value brought to the operator.

If the distribution condition of the operation service of the user terminal under the interference source in the second interference information represents that the number of the user terminals operating the downlink type service reaches the fifth threshold, or the percentage of the user terminals operating the downlink type service reaches the sixth threshold, it indicates that the interference source is mainly a data sender, the network coordination controller may determine a 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 strategy for the target network device includes adjusting the power of the target network device according to the power adjustment amount until the interference is reduced to a preset degree.

It should be noted that, for the first interference information, the third threshold and the fourth threshold used for determining the data sending side and the third threshold and the fourth threshold used for determining the data receiving side may be the same or different, and may be specifically set according to actual requirements. Similarly, for the second interference information, the fifth threshold and the sixth threshold used for determining the data sending side and the fifth threshold and the sixth threshold used for determining the data receiving side may be the same or different, and may be set according to actual needs.

S203: and adjusting the working state of the target network equipment according to the control strategy.

Specifically, when the control policy 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 working mode of the target network device to the user terminal, so that the user terminal resets the split mode of the target network device.

When the control policy is to adjust the power of the target device according to the power adjustment amount until the interference is reduced to a preset degree, the network coordination controller may send the power adjustment amount to the target network device, and instruct the target network device to adjust the power according to the power adjustment amount.

And when the control strategy is to release the user terminal under the target network equipment, sending the control strategy to the first network equipment to instruct the target network equipment to send instruction information to the user terminal and instruct the user terminal to release the network connection with the target network equipment.

As can be seen from the above, when a first network and a second network are merged, a new logical network element, that is, a network coordination controller, is introduced to an upper layer of the first network and the second network, and the new logical network element can receive first information reported by a first network device and/or second information reported by a second network device, determine a control policy for a target network device by using a coordination algorithm based on the first information and/or the second information reported by the network device, and adjust a working state of the network device based on the control policy, for example, adjust an uplink and downlink mode of the network device or a power of a certain network device, so as to balance a load on a network side, reduce network interference, have high availability, and meet user requirements.

In order to facilitate understanding of the technical solution of the present application, the network coordination control method will be further exemplarily described below with reference to a timing chart.

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

1. UE reports the service characteristics of the user on the uu port;

specifically, when the UE watches the video, the service characteristic is reported as a downlink service, and when the UE performs video live broadcasting, the service characteristic is reported as an uplink service;

2. the UE reports first interference information on a uu port, wherein the first interference information comprises information such as a channel, SSID/BSSID and signal strength of an interference source obtained by interference measurement of the UE;

3. the method comprises the steps that a cellular eNB/gNB collects service characteristic information of a plurality of UE (user equipment), WLAN (wireless local area network) information related to the UE and first interference information under a network element and sends the service characteristic information, the WLAN information and the first interference information to a cellular WLAN cooperative controller;

4. performing interference measurement on the WLAN AC/AP to obtain second interference information, and sending the second interference information to a cellular WLAN cooperative controller;

5. the cellular WLAN cooperative controller determines a control strategy aiming at target network equipment by utilizing a cooperative algorithm based on the summarized service characteristic information, the WLAN information associated with the UE, the first interference information and the second interference information;

specifically, the network coordination controller performs optimization calculation such as a DL/UL working mode of a certain AP of the WLAN, channel/power configuration of the AP, release of the WLAN, and the like based on information summarized by the plurality of cellular enbs/gnbs and the WLAN AC/APs;

6. the 'cellular WLAN cooperative controller' outputs through the cooperative algorithm: information such as a certain AP DL/UL working mode of the WLAN, WLAN release and the like is sent to the cellular eNB/gNB;

7. the cellular eNB/gNB generates and sends configuration information of the UE to the UE, and if the AP works in a DL only mode, the data distribution mode of the UE under the AP is reset to be uplink non-distribution; if the AP working mode is ULonly, resetting the shunting algorithm under the AP as downlink non-shunting; if a certain UE does not perform uplink and downlink shunting, the WLAN connection can be released;

8. the 'cellular WLAN cooperative controller' outputs through the cooperative algorithm: power up/down/channel reconfiguration/frequency range reset of a certain AP, etc., the WLAN AC/AP performs this operation.

In the above embodiment, the sequence of steps 1 and 2 may be arbitrary, for example, it may be executed simultaneously or sequentially, and similarly, the sequence of steps 3 and 4 and the sequence of steps 6 and 8 may also be arbitrary, as pointing to steps 3 and 4, and executing steps 6 and 8 simultaneously.

In practical applications, the network coordination controller may also implement network coordination control only according to service characteristics or only according to interference information, which is described in detail below with reference to the timing diagram.

Referring to the timing diagram of the network coordination control method shown in fig. 4, in the method, the UE has completed UE capability negotiation, air interface measurement, and WLAN connection establishment of the cellular and WLAN, and the method includes:

1. UE reports the service characteristics of the user on the uu port;

2. the method comprises the steps that a cellular eNB/gNB collects service characteristic information of a plurality of UE (user equipment) and WLAN (wireless local area network) information related to the UE under a network element and sends the service characteristic information and the WLAN information to a cellular WLAN cooperative controller;

3. the cellular WLAN cooperative controller determines a control strategy aiming at target network equipment by utilizing a cooperative algorithm based on the summarized service characteristic information and the associated WLAN information;

specifically, the cellular WLAN cooperative controller performs optimization calculation on a DL/UL working mode of a certain AP of the WLAN based on information summarized by a plurality of cellular eNBs/gNBs and WLAN AC/APs;

4. the 'cellular WLAN cooperative controller' outputs through the cooperative algorithm: a certain APDL/UL working mode of the WLAN and sending to the cellular eNB/gNB;

5. the cellular eNB/gNB generates and sends configuration information of the UE to the UE, and if the AP works in a DL only mode, the data distribution mode of the UE under the AP is reset to be uplink non-distribution; if the working mode of the AP is UL only, the shunting algorithm under the AP is reset to be downlink non-shunting.

In this embodiment, when the WLAN air interface only receives downlink data, since the downlink data is sent by the network side device, the air interface is less occupied, the transmission efficiency of the WLAN air interface is improved, and when the WLAN air interface only receives uplink data, a higher data sending rate supplement can be provided for the cellular network. For example, the uplink coverage of the cellular network is limited for a far-point user, the cellular network is changed into a full uplink mode through the WLAN, and the WLAN data transmission rate is high.

Next, referring to a timing diagram of a network coordination control method shown in fig. 5, in the method, a UE has completed UE capability negotiation, air interface measurement, and WLAN connection establishment of a cellular network and a WLAN, the method includes:

1. the UE reports first interference information on a uu port;

the interference information comprises information such as a channel, SSID/BSSID, signal strength and the like of an interference source;

2. the method comprises the steps that WLAN information and first interference information related to UE under a network element are collected by a cellular eNB/gNB and sent to a cellular WLAN cooperative controller;

3. the WLAN AC/AP carries out interference measurement to obtain second interference information and sends the second interference information to the cellular WLAN cooperative controller;

4. the cellular WLAN cooperative controller determines a control strategy aiming at the target network equipment by utilizing a cooperative algorithm based on the received first interference information, the associated WLAN information and the second interference information;

specifically, based on the information summarized by a plurality of cellular eNBs/gNBs and WLAN AC/APs, optimization calculation such as AP power/channel configuration and WLAN release is performed;

5. the 'cellular WLAN cooperative controller' outputs through the cooperative algorithm: releasing information such as WLAN; and send to cellular eNB/gNB;

6. the cellular eNB/gNB generates and sends the configuration information of the UE to the UE and indicates to release the connection with the WLAN;

7. the 'cellular WLAN cooperative controller' outputs through the cooperative algorithm: power up/down/channel reconfiguration/frequency range reset of a certain AP, etc., the WLAN AC/AP performs this operation.

In this embodiment, the cellular WLAN cooperative controller obtains the channel and service conditions of APs in a management range, or obtains the AP conditions in a non-management range through information interaction between centralized control points, and controls the current unimportant APs to reduce the influence on the important APs, such as power reduction/user release, based on user access and SLA guarantee conditions under each AP. The interference of the WLAN AP can be inhibited by identifying the interference AP, releasing the user under the interference AP, adjusting the service and the like, and increasing/reducing the power of the AP, reconfiguring the channel, resetting the frequency range.
