Technical Field

Background

The quality assurance of mobile network traffic depends on the management of the end-to-end network, wherein when the demands of the application traffic on the network and the capabilities provided by the network match, both the application traffic can be optimized and the network resources can be fully utilized. Under the existing 3GPP (3 rd Generation Partnership Project, third generation partnership project) system, application services interact through a core network, so the main scheme for controlling the service quality of an application currently is as follows: the core network obtains the quality requirement of the application service through DPI (Deep Packet Inspection, deep packet analysis), and then the quality requirement of the application service is acted on the network through a corresponding quality control strategy, mainly QoS (Quality of Service ) regulation strategy.

However, since the quality of the mobile Network is limited by the congestion status of the wireless Network in real time and the fluctuation of the wireless Network channel, and according to the connection relationship of the 5G (5 th-Generation, fifth Generation mobile communication technology) Network architecture as shown in fig. 1 and the description of the Network functions in 3gpp TS 23.501, the Access Network (radio Access Network) and the capability openness node do not have a connection relationship, and the Access Network and the capability openness node do not have a communication protocol, the core Network does not know the Network status of the wireless Network, and therefore, when the core Network regulates the Network quality based on the QoS regulation policy, the core Network is not well applied in the current Network architecture.

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but 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.

In the existing 5G network architecture, the access network and the capability opening node do not have a connection relationship, and the access network and the capability opening node do not have a communication protocol, so that wireless network information of the access network cannot be opened through NEF or AF, and therefore a core network does not know the network condition of the wireless network, and when the core network regulates and controls the network quality in a network quality regulation strategy based on QoS, a good optimization effect is not obtained in the current network, and therefore application experience of a user is not optimized, and network resources are not fully utilized.

Therefore, to overcome the above technical problems, an embodiment of the present invention provides an information sending method, including:

and sending the access network capability information.

Wherein, sending the access network capability information includes any one of the following modes:

an access network sends the access network capability information;

the DU transmits access network capability information;

the CU sends access network capability information.

Therefore, the network condition of the current wireless network of the access network, namely the access network capability information of the access network, is sent through the access network or the DU or the CU, so that the mobile network executes a corresponding network quality regulation strategy according to the access network capability information of the access network, and meanwhile, the application equipment can regulate and control the application data of the current access application according to the access network capability information of the access network.

Specifically, when the access network or the DU or the CU sends the access network capability information, the triggering may be based on the locally stored configuration information, that is, when the triggering event of sending the access network capability information is currently satisfied, or when the reporting period of the access network capability information is reached, the access network capability information of the access network is automatically sent.

Or when the access network or the DU or the CU sends the access network capability information, the triggering may also be based on first information sent by other devices, and in this embodiment of the present invention, the request information, the control information, the query information, the indication information, or the configuration information is regarded as first information, that is, the first information is the request information, the control information, the query information, the indication information, or the configuration information, where the first information is used to request the DU to send the access network capability information, so if the access network receives the request information, the control information, the query information, the indication information, or the configuration information sent by other devices, the access network capability information of the access network is sent.

That is, the access network or DU or CU decides whether to send access network capability information; and if so, sending the access network capability information of the access network.

Specifically, the access network or DU or CU deciding whether to send access network capability information includes:

if a first message for transmitting the access network capability information is received, determining to transmit the access network capability information; or according to the locally stored configuration information, determining to send the access network capability information when determining that the triggering event of sending the access network capability information is met currently or the reporting period of the access network capability information is reached.

The procedure of triggering the access network or the DU or CU to send access network capability information as described above is then described below in connection with specific embodiments, respectively.

Embodiment one:

when an access network transmits its own access network capability information based on locally stored configuration information, an embodiment of the present invention provides an information transmission method, as shown in fig. 2, including the steps of:

step S201: the access network transmits access network capability information.

Specifically, the sending access network capability information includes:

transmitting access network capability information through a user plane data packet; or (b)

Transmitting access network capability information through signaling; or (b)

Transmitting access network capability information through data packets related to network slices; or (b)

The access network capability information is sent through network slice related signaling.

That is, the access network may send access network capability information via the user plane data packet; the access network capability information can also be sent through signaling; the access network capability information can also be sent through the data packet related to the network slice; access network capability information may also be sent through network slice related signaling. It will be understood, of course, that in the embodiment of the present invention, the manner in which the access network capability information is transmitted by the access network is not specifically limited.

It should be noted that, the network slice is a concept introduced by the 5G mobile network, specifically, a logic network providing specific network capabilities and characteristics; it can be used by operators to provide network services with mutually isolated and customizable functions for different vertical industries, different customers and different services based on Service level Agreement SLA business service agreements signed by customers. For a description of network slicing see in particular 3gpp ts23.501.

Specifically, in the embodiment of the present invention, the access network sending the access network capability information includes:

And the access network capability information includes at least one of the following information:

information of bandwidth which can be provided by the access network currently;

information of network rate that the access network can currently provide;

information of network quality that the access network can currently provide;

the access network can provide cached information currently;

That is, when the access network transmits the access network capability information, the access network may transmit, according to the locally stored configuration information, a parameter value corresponding to one or more of bandwidth information (available bandwidth information) that the access network can currently provide, network rate information (available network rate information) that the access network can provide, network capacity information (available network capacity information) that the access network can provide, network quality information (available network quality information) that the access network can provide, cache information (available cache information) that the access network can provide, computing capability information (available computing capability information) that the access network can provide, or computing resource information (available computing resource information) that the access network can provide, and may transmit an indication information indicating whether the access network capability information that the access network can currently provide meets the access network capability requirement of the application or the user.

When the access network sends the indication information whether the access network capability information which can be provided by the access network meets the access network capability requirement of the application or the user, the method specifically comprises the following steps:

if the access network capability requirement of the application or the user in the locally stored configuration information is 20M bandwidth for the expected access network, the access network judges whether the 20M bandwidth can be provided according to the current wireless state of the access network, and if so, the access network sends indication information capable of providing the 20M bandwidth; if not, an indication that 20M bandwidth cannot be provided is transmitted. Specifically, the access network may indicate that itself can provide a bandwidth of 20M by transmitting 1, that is, the access network transmits indication information of 1 at this time, or may indicate that itself cannot provide a bandwidth of 20M by transmitting 0, that is, the access network transmits indication information of 0 at this time.

In the embodiment of the present invention, the access network capability requirement of the application or the user is specifically, which type of information included in the access network capability information is not specifically limited. Also, the form of the indication information of whether the access network capability information currently available to the access network satisfies the access network capability requirement of the application or the user is not particularly limited.

Therefore, in the embodiment of the invention, the access network capacity information which can be provided by the mobile network is actively sent through the access network, so that the mobile network can execute the corresponding network quality regulation strategy according to the access network capacity information of the access network, and meanwhile, the application equipment can regulate and control the application data of the current access application according to the access network capacity information of the access network, thereby not only improving the application experience of a user, but also avoiding the waste of network resources.

Embodiment two:

when the access network transmits its own access network capability information based on the received first information, the embodiment of the invention provides an information receiving method, as shown in fig. 3, which includes:

step S301: the access network receives the first information.

The first information is used for requiring the access network to send access network capability information, and the first information is request information, control information, inquiry information, indication information or configuration information.

Specifically, in the embodiment of the present invention, the access network receiving the first information includes:

The access network receives request information or control information sent by AMF or SMF; or (b)

The access network receives the sending request information, the control information, the inquiry information, the indication information or the configuration information, so that the access network can send the access network capability information according to the control, the configuration or the indication, and the problem that the access network cannot perform capability opening in the prior art can be solved in a configuration enabling aspect, thereby realizing regulation and control on the service and the network quality based on the network condition of the wireless network.

Specifically, the process of the NEF transmitting request information, control information, inquiry information or indication information to the access network is as shown in fig. 4, that is, the NEF may directly request information from the access network. The procedure of the AMF or SMF transmitting the request information or the control information to the access network is shown in fig. 5, that is, when the AMF or SMF transmits the request information to the access network, it is necessary to acquire the request information or the control information from the NEF first, and then forward the request information or the control information to the access network. The process of the UPF sending the query or indication information to the access network is shown in fig. 6, that is, the UPF needs to acquire the query or indication information from the NEF before forwarding the query or indication information to the access network. It will be understood, of course, that in the embodiment of the present invention, a path for acquiring the first information by the access network is not specifically limited.

Specifically, in the embodiment of the present invention, the first information is used to request the access network to send indication information about whether the access network capability information that can be provided by the access network currently meets the access network capability requirement of an application or a user; or (b)

Since the access network capability information includes at least one of the following information:

information of bandwidth which can be provided by the access network currently;

information of network rate that the access network can currently provide;

information of network quality that the access network can currently provide;

the access network can provide cached information currently;

Therefore, when the access network sends the access network capability information of the access network based on the first information, the access network can send the available bandwidth information, the available network rate information, the available network capacity information, the available network quality information, the available cache information, the available computing capability information or the parameter value corresponding to one or more information among the available computing resource information according to the current network condition of the access network, and can also send the indication information whether the access network capability information which can be provided by the access network meets the access network capability requirement of an application or a user.

In order to explicitly indicate which type of information is specifically transmitted when the access network transmits the access network capability information, in the embodiment of the present invention, the first information carries at least one of the following information:

access network capability requirement information of an application or user;

Wherein, the information type includes an index of information and an object of the index, the information index refers to available bandwidth information, available network rate information, available network capacity information, available network quality information, available buffer information, available computing power information or available computing resource information of an access network, and the object of the index refers to whether the information index to be transmitted currently is user-level information or service-level information or application-level information; the feedback path is the target receiving device of the access network sending the access network capability information; by information format is meant that the access network is transmitted in the format of the corresponding parameter values of the access network capability information or in the format of the corresponding preset discrete levels of the access network capability information; the unit information refers to a unit, such as bytes, when the access network transmits the access network capability information; the triggering event of sending the access network capability information or stopping sending the access network capability information means that a certain preset condition is met; the reporting period of the access network capability information is that a preset reporting time is reached; the information smoothing window is the duration of information statistics performed by the access network. The access network capability requirement information of an application or a user is reference information for decision-making access network capability allocation, decision-making, which is transferred to the access network, i.e. the access network is enabled to allocate resources directly according to the requirements of the application or the user.

Specifically, the access network may directly obtain the network requirement of the application according to the current access application of the application device, or obtain the network requirement of the user from the core network. When the core network obtains the network requirement of the user, the core network also needs to obtain the network requirement according to the current access application of the application equipment. The access network or the core network may be calculated according to the context information sent by the application device when the application device accesses the application to obtain the network requirement of the application, where the context information includes, but is not limited to, a time length of a video slice, a video code rate level list, a user expected bandwidth rate, a list of user expected bandwidth rates, and the like.

Specifically, when the feedback path carried in the first information is a UPF, the access network sends its own access network capability information to the UPF, and if the feedback path carried in the first information is a NEF, the access network sends its own access network capability information to the NEF. And are not illustrated herein.

It should be noted that, in the embodiment of the present invention, the sending device that sends the first information may be the same as or different from the target receiving device that receives the access network capability information. That is, when the NEF transmits the indication information to the access network, the access network may be instructed to transmit the access network capability information to itself, or the access network may be instructed to transmit the access network capability information to other devices. Therefore, in the embodiment of the present invention, the target receiving device that receives the access network capability information may be specified according to the connection status and the requirement of the current network architecture, so in the embodiment of the present invention, the feedback path for sending the access network capability information by the access network is not specifically limited.

Specifically, when the application accessed by the application device is a video application, the video code rates corresponding to the videos with different resolutions are different, so that the corresponding code rate level can be set for the videos with different resolutions, for example, the video code rate can be expressed as 720P by 1, and the video code rate can be expressed as 1080P by 2. The first information may thus instruct the access network via the information format to send bandwidth information that it is currently able to provide, or the level that the access network is currently able to provide.

Specifically, the trigger event that causes the access network to send the access network capability information or stop sending the access network capability information may be a service type of an application, or may be an IP address of the wireless network. For example, the service types of the application can be divided into video service, call service and the like, so that the triggering event can be set as when the currently accessed video service is the video service, and the access network is triggered to send the access network capability information or stop sending the access network capability information. It will be understood, of course, that in the embodiment of the present invention, a trigger event or a reporting period for the access network to send the access network capability information may be set according to actual requirements, so in the embodiment of the present invention, this is not specifically limited.

Specifically, the information smoothing is a method for processing information, that is, an effective basic "present" amount is estimated from a series of "past" information amounts, and the information smoothing window refers to a "past" duration of information statistics, for example, the information smoothing window is 20S, which indicates that the access network performs integrated processing on access network capability information in the past 20S, estimates bandwidth information that can be provided by the access network in a future period, and when a transmission period is reached, transmits the estimated access network capability information to other devices.

The information carried in the first information is acquired from AF or AS.

Specifically, as shown in fig. 3, the method further includes:

step S302: and sending the access network capability information of the access network according to the first information.

That is, after receiving the first information, the access network needs to send relevant information that the user or the application expects to send by the access network according to the information carried in the first information.

Therefore, in the embodiment of the invention, the access network sends the access network capability information which can be provided by the mobile network according to the first information, so that the mobile network can execute the corresponding network quality regulation strategy according to the access network capability information of the access network, and meanwhile, the application equipment can regulate and control the application data of the current access application according to the access network capability information of the access network, thereby improving the application experience of a user and improving the utilization rate of network resources.

As can be seen from the foregoing, the first information is request information, control information, inquiry information, indication information or configuration information, so when the first information is request information, the method further includes:

and the access network sends response information.

The response information sent by the access network is used for informing the NEF or the AMF or other equipment that the request information is received, and sending the access network capability information according to the request information. Wherein the response information may directly carry access network capability information. That is, as shown in fig. 7, after receiving the request information sent by the NEF or the AMF, the access network carries response information of the access network capability information to the NEF or the AMF, so that the NEF or the AMF obtains the current wireless network condition of the access network.

When the first information is request information, if the access network has no openable access capability information, the method further comprises:

That is, as shown in fig. 8, when the access network temporarily has no openable access capability information, or is unable to open its own access capability information to the core network or the terminal for other reasons, the NEF or the AMF sends failure information to the network, and informs the NEF or the AMF of the reason that the access network cannot send the access capability information through the failure information, so that the NEF or the AMF performs quality control based on the currently executed quality control policy after receiving the failure information sent by the access network.

Because the final target receiving device of the access network capability information is UE and AS, and when the access network sends the access network capability information to the AS, the access network needs to be forwarded by the related device of the core network, so the process of sending the access network capability information to the core network is actually included in the process of sending the access network capability information to the AS. Therefore, the sending the access network capability information of the access network includes:

the access network sends the access network capability information to the UE; or (b)

The access network sends the access network capability information to an AS.

A specific procedure for the access network to transmit access network capability information will be described below in connection with specific embodiments.

When the access network capability information is sent through the user plane data packet, the access network capability information may be specifically carried in a packet header of the user plane data packet or some fields of a packet body of the user plane data packet, which is not specifically limited in the embodiment of the present invention.

The air interface signaling may be RRC (Radio Resource Control ) signaling, or MAC CE signaling. It will be understood, of course, that in the embodiment of the present invention, the form of the user plane data packet and the air interface signaling for transmitting the access network capability information is not specifically limited.

The process of sending the access network capability information to the UE by the access network is shown in fig. 9, that is, the access network will carry the access network capability information in a user plane data packet, or in a packet header of the user plane data packet, or in an air interface signaling, and then directly send the user plane data packet or the air interface signaling carrying the access network capability information to the UE, so that the UE can obtain the access network capability information of the access network.

The access network capacity information of the UE is sent to the UE through the access network, so that the access network can open the capacity of the UE, the UE can know the current wireless network according to the received access network capacity information, the application data of the current access application can be regulated and controlled, the application experience of a user is improved, network resources can be reasonably utilized, and the waste of the network resources is avoided.

That is, the access network transmits the access network capability information to the AS or the NEF through the UPF after transmitting the access network capability information to the UPF.

Specifically, the method further comprises:

That is, after the access network sends the access network capability information to the UPF, if the UPF sends the access network capability information to the NEF, the access network capability information needs to be sent to the AF or the AS or the UE through the NEF.

The process of sending the access network capability information by the access network through the UPF is shown in fig. 10, that is, the access network encapsulates the access network capability information in a user plane data packet, or a packet header of the user plane data packet, and then sends the user plane data packet carrying the access network capability information to the UPF, so that the UPF can obtain the access network capability information of the access network.

After receiving the access network capability information sent by the access network, the UPF may send the access network capability information in the following manner:

mode one: the UPF further encapsulates the user plane data packet carrying the access network capability information in an application layer data packet, and sends the application layer data packet to the AS, so that the AS can acquire the access network capability information of the access network.

Mode two: the UPF forwards the user plane data packet carrying the access network capability information to the NEF, and then the NEF forwards the access network capability information carried by the user plane data packet to the AF or AS or UE so that the AF or AS or UE can acquire the access network capability information of the access network.

The first and second modes may be two parallel transmission modes, and may be used alone or simultaneously, so in practical application, an appropriate transmission mode may be selected according to the current open demand, and therefore in the embodiment of the present invention, the mode for transmitting the access network capability information by the UPF is not specifically limited.

In the embodiment of the present invention, the data packet sent by the access network to the UPF may be a GTP-U data packet. Specifically, a schematic diagram of a GTP-U packet provided by an embodiment of the present invention is shown in table 1.

mode one: AS shown in fig. 12, the NEF directly sends signaling carrying access network capability information to the AF or AS or UE, so that the AF or AS or UE can acquire the access network capability information of the access network.

Mode two: AS shown in fig. 13, the NEF forwards the signaling carrying the access network capability information to the AF, and then the AF forwards the access network capability information carried in the signaling to the AS, so that the AS can acquire the access network capability information of the access network.

Therefore, the method further comprises: and the AF sends the access network capability information to the AS.

Example nineteenth:

according to another aspect of the present invention, there is also provided a quality of service adjustment method, as shown in fig. 27, the method including:

step S2701: and the application equipment receives the access network capability information sent by the access network.

Step S2702: and generating regulation and control information of application data aiming at the current access application according to the access network capability information.

According to the embodiment, the access network can send the access network capability information of the access network to the application device, namely the UE or the AS, so that the UE or the AS can regulate and control the application data of the current access application according to the current network condition of the access network after receiving the access network capability information sent by the access network, thereby improving the application experience of the user.

If the application currently accessed by the UE or the AS is a video application, and the bandwidth required for downloading the video is 10M, and the bandwidth information currently provided by the access network is 20M, the network requirement of the UE or the AS can be met, the UE or the AS downloads the corresponding video with the bandwidth of 10M, thereby avoiding the waste of bandwidth resources. However, if the bandwidth information that the access network can currently provide is 5M, in order to ensure that the access to the video application is smooth, the UE or AS may adjust the bandwidth of the access to the video application to 5M.

Wherein, to enable the mobile network quality and the service quality to maintain consistency in the regulation process, the method further comprises:

Specifically, the application device sends the network requirement and/or requirement indication of the current access application to the mobile network, so that the mobile network executes the corresponding network quality control strategy according to the network requirement and/or requirement indication of the current access application of the application device.

That is, the application device sends the network requirement and/or requirement indication of the previous access application to the mobile network, so that the mobile network can execute the corresponding network quality control policy based on the network requirement and/or requirement indication of the application device, thereby ensuring the bandwidth required by the application device and not wasting network resources.

Wherein when the application device is an AS, the sending, by the application device, a network requirement and/or a requirement indication of a current access application to a mobile network includes:

and the AS sends the identification information corresponding to the current access application of the AS to the mobile network, wherein the identification information is correspondingly set by the AS according to the received access network capability information.

That is, the AS may divide the received access network capability information into different levels, for example, when the bandwidth information that the access network can provide is 10M, the AS may set identification information corresponding to the access network capability information, where the identification information may be in the form of a tag or a value, if in the form of a tag, the AS may set the value corresponding to the bandwidth information of 10M to 1, and when the bandwidth information that the access network can provide is 20M, the AS may set the value corresponding to the bandwidth information of 20M to 2, so the AS may inform the mobile network of the current network requirement by transmitting 1 or 2 to the mobile network.

It will be understood, of course, that in the embodiment of the present invention, the form of adding the identification information corresponding to the access network capability information to the AS is not specifically limited.

Example twenty:

according to another aspect of the present invention, there is also provided a network quality regulation method, as shown in fig. 28, the method including:

step S2801: the mobile network identifies network requirements of the application device for current access to the application.

Step S2802: and executing a corresponding network quality control strategy according to the identified network requirement of the application equipment for accessing the application currently.

In the embodiment of the invention, the mobile network comprises an access network and a core network, and the above embodiment shows that the access network can open the capability to the core network, so that after the mobile network receives the network requirement of the current access application of the terminal sent by the terminal, the access network and the core network can execute the corresponding network quality control strategy according to the network requirement of the current access application of the application device, thereby ensuring the bandwidth required by the application device and not wasting network resources.

If the application currently accessed by the application device is a video application, and the bandwidth required for downloading the video is 10M, and the bandwidth information that can be provided by the access network is 20M, so that the access network and/or the core network can only provide the bandwidth of 10M for the application device under the condition of ensuring that the user requirement can be met, in order to avoid resource waste. However, if the bandwidth information that the access network can only provide is 5M, in order to avoid causing poor application experience of the user, the access network and the core network can first save the bandwidth that provides 5M to the application device by executing the corresponding network quality control policy, and when the bandwidth that the access network can provide is 10M, the bandwidth that provides 10M to the application device.

Wherein the network requirements and the demand indications of the application device currently accessing the application can be carried in the application data packet or the packet header of the application data packet. In particular, it may be explicitly or implicitly included in the packet sequence number, tag, indication bit, or directly in the header content of the packet, i.e. the requirements and/or the indication of the requirements of the network.

When the application device is an AS, the mobile network identifying the network requirement of the application device for accessing the application currently includes:

From the above, the AS may divide the received access network capability information into different levels, and set identification information corresponding to each level, so that the mobile network may identify the AS's current access application network requirement according to the identification information sent by the AS.

Example twenty-one:

AS can be seen from the above, the first information received by the access network is obtained from the AF or AS, so that the interaction flow of the application device (AS or UE) with the mobile network is shown in fig. 29, and includes the following steps:

step S2901: an application device (AS or UE) sends a network quality request to a mobile network.

The request may carry a network requirement and/or a requirement indication of the current access service of the application device (AS or UE).

Step S2902: the mobile network performs a network quality response to the application device (AS or UE), wherein the network quality response carries access capability information of the access network.

Step S2903: the mobile network performs a corresponding network quality control policy based on the network requirements of the application device (AS or UE) currently accessing the service.

Step S2904: an application device (AS or UE) regulates and controls application data of a current access application based on network requirements of a current access service and bandwidth information which can be provided by an access network.

Therefore, the access network capability information of the mobile network is opened to the application equipment (AS or UE) or the core network through the access network, so that the end-to-end quality assurance pull-through of the mobile network can be realized, and the application experience of a user and the utilization rate of network resources are improved.

Since the mobile network includes a core network and an access network, after the mobile network receives a network quality request sent by a terminal, an interaction flow between the core network and the access network is shown in fig. 30, and includes the following steps:

step S3001: the core network may send a wireless network quality request to the access network based on a network quality request sent by an application device (AS or UE).

Step S3002: the access network performs wireless network quality response to the core network, wherein the wireless network quality response carries network access capability information of the access network.

Step S3003: the access network may implement a corresponding network quality control policy based on network access capability information that itself is capable of providing and network requirements of the application device (AS or UE).

Step S3004: after receiving the wireless network quality response sent by the access network, the core network can also execute a corresponding network quality control policy based on network access capability information that can be provided by the access network and network requirements of application equipment (AS or UE).

In step S3003 and step S3004, the mobile network performs network quality control, so that the core network and the access network may perform network quality control simultaneously, or the core network or the access network may perform network quality control separately. Therefore, in the embodiment of the present invention, the executing the corresponding network quality control policy includes:

Specifically, when the mobile network is a core network and the core network performs network quality regulation, the method includes:

and generating regulation and control information aiming at application data according to the access network capability information and the network requirement of the application equipment for accessing the application currently.

That is, the core network may provide the application device with a corresponding bandwidth based on the access network capability information and the network requirement of the application device currently accessing the application, and then execute a corresponding network quality control policy for the application data bandwidth requirement of the application device currently accessing the application, so as to ensure that the bandwidth requirement of the application device can be met.

Specifically, in the 5G scenario, the interface between the core network and the access network is an NG interface, so a process of wireless network quality response is defined on the interface, and further, an associated NG-U interface may be adopted, and the wireless network quality information is carried by the user plane packet or the packet header of the user plane packet, that is, step S3005 below.

S3005: and the access network sends the quality information of the associated wireless network to the core network.

Thus, on the basis of the above, the application device (AS or UE) also comprises the following steps in the process of interacting with the mobile network:

step S3905: the mobile network transmits the road network quality information to an application device (AS or UE).

As can be seen from the foregoing, the access network includes CUs and DUs, so in the foregoing embodiment of the present invention, the executing the corresponding network quality control policy includes:

The corresponding network quality control policy is executed through the DU.

Example twenty two:

AS can be seen from the above embodiments, the core network sends a radio network quality request to the access network, because the AS or the UE has received the network quality request, and thus the AS has open capability of initiating the access network to the access network, the AS may send the quality request to the AF and then send the quality request to other core network devices by the AF, so the process is AS shown in fig. 31, i.e. the AS/AF will send the network quality request to the NEF, the NEF will forward the network quality request to the AMF/SMF after receiving the network quality request, and the AMF/SMF will send the request information to the CU in the access network after receiving the request information.

The CU may send access network capability information of the access network to the AMF/SMF directly according to the network quality request. Meanwhile, the CU can also send the received network quality request to the DU, so that the DU can send the access network capability information of the access network to the CU and then forward the access network capability information to the AMF/SMF.

It should be noted that, the CU may be an optional step of forwarding the received network quality request to the DU, so the embodiment of the present invention is not limited in particular.

The AMF/SMF forwards the access network capability information to the NEF after receiving the access network capability information sent by the CU, and the NEF forwards the access network capability information to the AS or the AF again after receiving the access network capability information sent by the CU, so that the access network can be opened to the AS or the AF finally.

Example twenty-three:

The CU may send access network capability information of the access network directly to the NEF according to the network quality request. Meanwhile, the CU may also send the received network quality request to the DU, so that the DU sends access network capability information of the access network to itself, and then forwards the same to the NEF.

After receiving the access network capability information sent by the CU, the NEF forwards the access network capability information to the AS or the AF again, and finally, the access network opens the capability to the AS or the AF.

Example twenty-four:

on the basis of the above embodiment, the procedure of initiating the access network capability opening to the access network by the AS may also be AS shown in fig. 33, that is, initiating the access network capability opening to the access network by signaling of the control plane, that is, the AS/AF may send control signaling carrying the bandwidth available for the user to the NEF, after receiving the control signaling, the NEF may forward the control signaling to the UPF, and after receiving the control signaling, the UPF may send the control signaling to the CU in the access network again.

The CU may send access network capability information of the access network directly to the UPF according to the control signaling. Meanwhile, the CU can also send the received control signaling to the DU, so that the DU sends the access network capability information of the access network to the CU and then forwards the information to the UPF.

It should be noted that, the CU may further forward the received control to the DU as an optional step, so the method is not particularly limited in the embodiment of the present invention.

After receiving the access network capability information sent by the CU, the UPF forwards the access network capability information to the NEF, and after receiving the access network capability information sent by the CU, the NEF forwards the access network capability information to the AS or the AF again, so that the access network can open the capability to the AS or the AF.

Example twenty-five:

on the basis of the above embodiment, the procedure of initiating the access network capability opening to the access network by the AS may also be AS shown in fig. 34, that is, initiating the access network capability opening to the access network through the indication information of the data plane, that is, the AS/AF may send the indication information carrying the available bandwidth of the user to the DN, after receiving the indication information, the DN may forward the indication information to the UPF, and after receiving the indication information, the UPF may send the indication information to the CUs in the access network again.

The CU may send, directly according to the indication information, access network capability information of the access network to the UPF. Meanwhile, the CU may also send the received indication information to the DU, so that the DU sends the access network capability information of the access network to itself, and then forwards the information to the DN.

It should be noted that, the CU forwards the received control signaling to the DU as an optional step, so the method is not specifically limited in the embodiment of the present invention.

After receiving the access network capability information sent by the CU, the DN is forwarded to the AS or the AF again, and finally the access network is opened to the AS or the AF.

Example twenty-six:

on the basis of the above embodiment, in the embodiment of the present invention, taking AS an example the current access application device of the AS the video application device, the process of the AS deciding to play the bandwidth is described, where the process is shown in fig. 35.

The AS segments the video currently to be pushed into a plurality of video clips, wherein the duration of each video clip is the same. And then the duration of the video segment is sent to a core network, the core network calculates the bandwidth requirement for sending the video segment based on the duration of the video segment and sends a bandwidth estimation request to an access network, the access network carries out bandwidth estimation response to the core network according to the bandwidth currently available and the bandwidth requirement for issuing the video segment, and if the bandwidth currently available by the access network can meet the bandwidth requirement for issuing the video segment, the core network can provide the AS with the bandwidth meeting the bandwidth requirement for issuing the video segment. At this time, the AS will issue a video stream, so that in the process of issuing a video stream by the AS, the bandwidth requirement of the video clip issued by the AS can be always satisfied, so that the core network will execute a quality control policy based on QoS Flow (stream), and the access network will execute a quality control policy based on DRB (data radio bearer ), and send the video stream issued by the AS to the UE.

Example twenty-seventh:

on the basis of the above embodiment, in the embodiment of the present invention, taking the current access application device of the UE as the video application device as an example, the process of deciding to play the bandwidth by the UE is described, where the process is shown in fig. 36.

The UE may also segment the video currently to be downloaded or played into multiple video clips, where each video clip has the same duration. And then, the duration of the video segment is sent to an access network, wherein the access network transmits the duration of the video segment to a core network, the core network calculates the bandwidth requirement for sending the video segment based on the duration of the video segment, and sends a network quality request to the access network, and the access network responds to the core network according to the bandwidth available at present and the bandwidth requirement for downloading or playing the video segment.

If the bandwidth currently available to the access network can meet the bandwidth requirements for downloading or playing the video clip, the access network can directly provide the AS with a bandwidth that meets the bandwidth requirements for delivering the video clip. Or the core network provides the AS with the bandwidth meeting the bandwidth requirement of issuing the video fragment, and then the access network transmits the bandwidth to the UE.

At this time, the UE requests to send a video stream to the AS, so that in the process of sending the video stream by the AS, the bandwidth requirement of downloading or playing the video clip can be always met, so that the core network executes a quality control policy based on QoS Flow (stream), and the access network executes a quality control policy based on DRB (data radio bearer ), and sends the video stream sent by the AS to the UE.

According to the above, no matter the AS decides to play the bandwidth or the UE decides to play the bandwidth, the core network and the access network can provide the AS or the UE with corresponding bandwidths based on the network requirement of the AS or the UE for accessing the video service, so that the application experience of the user can be improved, and the waste of network resources can be avoided.

Specifically, the AS or the UE may send the video stream level to the core network or directly send the bandwidth expected when the AS or the UE accesses the current application, or the like, in addition to the duration of sending the video clip to the core network. In the embodiment of the present invention, this is not particularly limited.

In the process of deciding to play the bandwidth by the AS or the UE, the steps 1, 2 and 3 may be set to a one-time action, that is, when the AS or the UE accesses the current application, the core network only needs to send the request information to the access network once, and in the subsequent access process, the access network may periodically open the access network capability to the AS or the UE or the core network according to the period of the AS or the UE accessing the current application, such AS the duration of the video clip, etc.
