Description

Information processing method, terminal equipment, network equipment and application server

Technical Field

The present invention relates to the field of information processing technologies, and in particular, to an information processing method, a terminal device, a network device, an application server, a chip, a computer-readable storage medium, a computer program product, and a computer program.

Background

In the related art, the network status information provided by 3GPP (3rd Generation Partnership Project) has a problem that the network status information cannot be timely notified to the application layer, so as to timely adjust the behavior of the application layer to achieve the purpose of avoiding or reducing the influence of user sampling. Taking the network status information as a QoS (Quality of Service) parameter as an example, that is, taking the change of the QoS parameter as an example, the QoS parameter may change with the change of the condition, and in order to adapt the application to the change of the QoS, the QoS parameter needs to be notified to the application server through the network element of the 3 GPP. However, the process of notification may result in a large delay overhead, so that the application server cannot timely perceive the change of QoS. Specifically, in the related art, the QoS parameter provided by the network side for the terminal device may change frequently, when the QoS parameter changes, the base station on the network side may notify the change situation to the central application server through the core network, and the central application server may need to interact with the local application server to notify the change of the QoS parameter. It can be seen from the above analysis that the application server cannot timely obtain the change of the QoS, which may cause the application layer to be unable to timely adjust the corresponding application layer behavior, and therefore the terminal device may also be unable to timely adjust the corresponding application layer behavior according to the change of the QoS parameter, thereby resulting in poor experience of the user of the terminal device.

Detailed Description

So that the manner in which the features and aspects of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the invention, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings.

Technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all 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 technical scheme of the embodiment of the application can be applied to various communication systems, for example: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (Long Term Evolution, LTE) System, an LTE Frequency Division Duplex (FDD) System, an LTE Time Division Duplex (TDD), a Universal Mobile Telecommunications System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication System, or a 5G System.

For example, the communication system 100 applied in the embodiment of the present application may be as shown in fig. 1-1. The communication system 100 may include a network device 110, and the network device 110 may be a device that communicates with a UE120 (or referred to as a communication terminal, terminal). Network device 110 may provide communication coverage for a particular geographic area and may communicate with UEs located within that coverage area. Optionally, the Network device 110 may be a Base Transceiver Station (BTS) in a GSM system or a CDMA system, a Network device (NodeB, NB) in a WCDMA system, an evolved Node B (eNB or eNodeB) in an LTE system, or a wireless controller in a Cloud Radio Access Network (CRAN), or a Network device in a Mobile switching center, a relay Station, an Access point, a vehicle-mounted device, a wearable device, a hub, a switch, a bridge, a router, a Network side device in a 5G Network, or a Network device in a Public Land Mobile Network (PLMN) for future evolution, or the like.

The communication system 100 also includes at least one UE120 located within the coverage area of the network device 110. "UE" as used herein includes, but is not limited to, connections via wireline, such as Public Switched Telephone Network (PSTN), Digital Subscriber Line (DSL), Digital cable, direct cable connection; and/or another data connection/network; and/or via a Wireless interface, e.g., to a cellular Network, a Wireless Local Area Network (WLAN), a digital television Network such as a DVB-H Network, a satellite Network, an AM-FM broadcast transmitter; and/or another UE's device configured to receive/transmit communication signals; and/or Internet of Things (IoT) devices. A UE that is arranged to communicate over a radio interface may be referred to as a "radio communication terminal", "radio terminal" or "mobile terminal".

Optionally, a Device to Device (D2D) communication may be performed between UEs 120.

It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

With reference to fig. 1-2, the related processing when the network state information, especially the QoS parameter, changes in the related art will be described: when a fast moving terminal, the QoS provided by the network may change frequently. When the QoS of the service changes, the base station informs a core network element (such as an SMF or PCF), the SMF or PCF sends the changed situation to the AF through a capability openness network element NEF, the AF may also need to interact with a user plane application server (DN) to adjust the related behavior, and the dashed line shows the interface between a control plane network element and a user plane network element of the application server, and belongs to the category defined outside 3 GPP. Specifically, if the QoS of the 3GPP network changes on average every 2 seconds, and the time for the 3GPP network element to notify the application server and perform the corresponding operation also takes 2 seconds, the application layer may not respond to the change of the QoS at all times, that is, the QoS may change again when the application layer responds.

It can be seen that the time delay caused by the simultaneous AF and the adjustment of the 3GPP network element mainly comes from: 1) communication time between the 3GPP network element and the AF; and/or, 2) the communication time of the AF with the user plane server (DN). In some scenarios, the time delay caused by 1) and/or 2) may be long. Therefore, the change of the 3GPP network state information cannot be timely notified to the AF and the AF cannot interact with the DN to adjust in time.

In view of the foregoing problem, an embodiment of the present invention provides an information processing method, as shown in fig. 2, including:

step 21: the terminal equipment acquires network state information; the terminal equipment stores a first strategy, wherein the first strategy is used for representing the corresponding relation between the network state information and the application layer behavior; and the network state information is used for the terminal equipment to determine the application layer behavior to be executed.

An embodiment of the present invention further provides an information processing method, as shown in fig. 3, including:

step 31: the network equipment sends network state information to the terminal equipment;

An information processing method provided in an embodiment of the present invention, as shown in fig. 4, includes:

step 41: and the application server receives the changed condition of the adjusted application layer behavior and/or network state information sent by the terminal equipment.

The application layer may be understood as a protocol layer above the NAS layer, for example, a protocol layer corresponding to an operating system or an application installed in the terminal device.

The network status information may include QoS parameters. Wherein the QoS parameter comprises at least one of the following:

a 5G quality of service indication (5QI, 5G QoS Index), AN Allocation And Retention Priority (ARP), a determined data stream Bit Rate (GFBR), a Maximum data stream Bit Rate (MFBR), AN uplink or downlink Maximum Packet loss Rate, AN end-to-end Packet Delay Budget (PDB), AN Access Network (AN Access Network) -PDB, a Packet error Rate, a Packet Priority, AN average window, a resource Allocation type, a Maximum data burst capacity, a UE-Aggregate Maximum Bit Rate (AMBR), a session-AMBR.

The network status information may also include other parameters related to the network status, which are not listed here.

The application layer behavior may correspond to at least one of:

coding rate, coding format, occupied bandwidth, compression rate, data packet size, data packet sending interval/period, data packet sending time point, and terminal moving speed and track.

The application layer behavior may also include other application layer related behaviors, which are not listed here.

The network device may be a network element of 3GPP, and may include, for example, a core network device and an access network device; the access network device may include a base station, a WLAN access device, and the like, which are not exhaustive here.

Examples 1, 1,

The method for the terminal device to obtain the network status information may be as follows: and the terminal equipment receives the network state information sent by the network equipment.

Wherein, the network device may be: an access network device or a core network device. The following description is respectively made for the cases where the network device is an access network device and a core network device:

case 1, the network device is an access network device:

the terminal device receives network state information sent by an access network device, wherein the network state information is carried by an AS (Access stratum) message. That is, when the network device is an access network device, the access network device directly sends the network state information to the terminal device. Here, the access network device may be a base station.

The AS message may be a Radio Resource Control (RRC) message.

It should be noted that in this case, there may be two subsequent processing modes:

in a processing mode, network equipment, that is, access network equipment sends network state information to terminal equipment as long as the network state information is acquired. Correspondingly, the terminal device adjusts the application layer behavior to obtain the adjusted application layer behavior based on the changed network state information and the first policy under the condition that the network state information changes.

Whether the network state information changes or not can be compared by the terminal device according to the network state information obtained last time (or stored last time) and the received network state information, if the network state information is different, the terminal device can determine that the network state information changes, and further, the terminal device can adjust the application layer behavior based on the changed network state information and the first strategy to obtain the adjusted application layer behavior.

In another processing mode, the network state information may be sent to the terminal device when the access network device determines that the network state information changes. Correspondingly, the terminal device adjusts the application layer behavior to obtain the adjusted application layer behavior based on the changed network state information and the first policy under the condition that the network state information changes.

The difference from the previous processing method is that in this processing method, the terminal device does not need to judge whether the network status information changes again, but only receives the network status information sent by the access network device, the terminal device can consider that the network status information changes, and then determines the corresponding application layer behavior according to the first policy from the received network status information, and adjusts the application layer behavior to obtain the adjusted application layer behavior.

Case 2, the network device is a core network device:

the core network device receives network state information sent by the access network device, and the core network device sends an NAS message carrying the network state information to the terminal device.

Correspondingly, the terminal equipment receives network state information sent by core network equipment; wherein the network state information is carried by a NAS message.

The access network device may be a base station; the core network device may be a network element of a core network, such as an AMF or an SMF.

Taking the network state information as the QoS parameter as an example: after the base station senses the change of the QoS, the QoS parameters are sent to a core network element AMF or SMF, and the core network element AMF or SMF (through NAS signaling) is sent to the terminal equipment.

It should be noted that, in this case, there may be the following three subsequent processing modes:

in a processing mode, an access network device sends network state information to a core network device no matter whether the network state information changes or not; similarly, the core network device sends the network state information to the terminal device regardless of whether the network state information changes.

At this time, whether the network state information changes or not may be compared by the terminal device according to the network state information obtained (or stored) last time and the network state information received this time, and if the network state information is different, the terminal device may determine that the network state information changes, and further, the terminal device may adjust the application layer behavior based on the changed network state information and the first policy to obtain the adjusted application layer behavior.

In another processing mode, when the access network device determines that the network state information changes, the network state information may be sent to the core network device, and the core network device sends the network state information to the terminal device. Correspondingly, the terminal device adjusts the application layer behavior to obtain the adjusted application layer behavior based on the changed network state information and the first policy under the condition that the network state information changes.

In this processing mode, the terminal device may not need to determine whether the network state information changes again, but may consider that the network state information changes as long as the network state information sent by the access network device is received, and then use the received network state information as the changed network state information, and adjust the application layer behavior by using the changed network state information and the first policy to obtain the adjusted application layer behavior.

In another processing mode, the core network device determines whether the network state information is changed, if so, the core network device sends the network state information to the terminal device, otherwise, the core network device does not send the network state information to the terminal device. Correspondingly, the terminal device adjusts the application layer behavior to obtain the adjusted application layer behavior based on the changed network state information and the first policy under the condition that the network state information changes.

In this processing manner, the terminal device may not need to determine whether the network state information changes again, but may consider that the network state information changes as long as the network state information sent by the access network device is received, and then use the received network state information as the changed network state information, and adjust the application layer behavior by using the changed network state information and the first policy to obtain the adjusted application layer behavior.

The adjusting of the application layer behavior comprises adjusting encoding related parameters.

The application layer behavior corresponds to at least one of: coding rate, coding format, occupied bandwidth, compression rate, data packet size, data packet sending interval/period, data packet sending time point, and terminal moving speed and track.

In this example, for the foregoing two cases, whether the network device is an access network device or a core network device, the first indication may be received in advance;

the first indication is used for indicating whether the network equipment notifies the terminal equipment of the network state information.

The first indication may further indicate a specific notification manner.

For example, the first indication may be used to indicate whether the network device notifies the terminal device of a change condition of the network status information; or, the network device is used to indicate whether the network device notifies the terminal device of the network status information. The difference between the two is that the former is to send the network state information to the terminal device when the network state information changes, or the change situation of the network state information; the latter is that the network device may send the network status information to the terminal device regardless of whether the network status information has changed.

For another example, the first indication may further include network status information sent by an AS message or an NAS message.

For example, the first indication is used to indicate whether to directly notify the terminal of the change of the network state information through the 3GPP system, and may also indicate whether to notify the terminal through AS signaling or NAS signaling.

The first indication may be subscription information from a user, or may be that the terminal device sends the subscription information to the 3GPP network element through an NAS or AS message, or may be that the application server sends the subscription information to the 3GPP network element (that is, the network device).

The network side may return a second indication according to the first indication, where the second indication is used to indicate whether the network side supports notifying the terminal of the network status information, and a specific notification manner (e.g., notifying according to an AS or NAS message).

Or, the terminal device sends the first indication to the network according to the second indication, that is, after the terminal receives the second indication, the terminal device sends the first indication to the network according to the notification whether the network supports the network state information and the specific notification mode.

It should be noted that, taking the network status information as the QoS parameter as an example, there are many QoS change conditions, such as: a base station handover occurs; network congestion (e.g., a sudden increase in the number of users) has occurred; the terminal moves into or out of a specific range (e.g., the service range of the edge server), etc., and will not be described herein.

The changing of the network state information may include: changes in QoS parameters, changes in terminal device location, etc.

The location of the terminal device may be represented by GPS coordinates, the identity of the cell in which it is located, the identity of the base station, the TAI, etc. Such as a change in QoS if a terminal device has a base station handoff.

Examples 2,

In a case where the terminal device provided in example 1 acquires network status information from the network device, the processing of the terminal device further includes:

and the terminal equipment sends the adjusted change condition of the application layer behavior and/or the network state information to an application server through a 3GPP system user interface.

Accordingly, the processing of the application server may include: and the application server receives the changed condition of the adjusted application layer behavior and/or network state information sent by the terminal equipment.

Based on the foregoing example 1, it can be seen that the terminal device may determine whether the network state information changes by itself, or may determine whether the network state information changes by a network device (such as an access network device or a core network device), and if the terminal device determines whether the network state information changes, the terminal device may compare the network state information currently received with the network state information stored in the previous time, and if the network state information is different from the network state information stored in the previous time, determine that the network state information changes.

The change condition of the network state information may include at least one of: the network state information changes to increase or decrease, the change value of the network state information, the last saved network state information, the current network state information, and the like.

Taking the network status information as the QoS parameter as an example, the change condition of the network status information may be understood as the change condition of the QoS parameter, and then the change condition may include: the change of the QoS parameter is increase or decrease, the change value of the QoS parameter, the last saved QoS parameter, the current QoS parameter and the like.

Or, there may be another situation, if the network device senses whether the network state information changes, if so, the changed network state information is sent to the terminal device; accordingly, the terminal device receives the network status information. In this case, the terminal device may determine that the network status information has changed as long as the network status information is received.

Likewise, the change condition of the network status information may include at least one of the following: the network state information changes to increase or decrease, the change value of the network state information, the last saved network state information, the current network state information, and the like.

Examples 3,

Different from the foregoing example, the present example may determine the current network status information according to a pre-configured predicted change situation of the network status information by the terminal device, specifically:

the terminal equipment acquires the change condition of the configured predicted network state information;

wherein the predicted change situation of the network state information comprises: and predicting different network state information corresponding to the terminal equipment in different areas and/or time.

And the terminal equipment determines the corresponding network state information according to the current area and/or time of the terminal equipment based on the predicted change condition of the network state information.

And under the condition that the network state information changes, the terminal equipment adjusts the application layer behavior based on the changed network state information and the first strategy to obtain the adjusted application layer behavior.

And then, the terminal equipment sends the adjusted change condition of the application layer behavior and/or the network state information to an application server.

The predicted change condition of the network state information may specifically be a predicted QoS change condition.

For example, the terminal device may also configure a predicted QoS change situation, such as that the terminal device predicts QoS parameters of different areas on a passing route according to a route to be moved. Alternatively, the QoS parameter corresponding to the time may be predicted according to the time point corresponding to the route to be moved. Or, according to the route to be moved, prediction can be performed to obtain different areas on the passed route and time points of reaching the different areas, so as to determine the corresponding QoS parameters.

The predicted change situation of the network state information may be obtained by: and the network equipment configures the predicted change condition of the network state information for the terminal equipment.

For example, the information may be sent to the terminal device for a network element of a 3GPP network.

In this example, the terminal device may adjust the policy in time when moving to the corresponding location according to a first policy, such as a QoS and behavior correspondence table.

The predicted route may be identified by a cell identifier, a base station identifier, a TAI, etc., for example, what QoS parameters are corresponding to different cell identifiers of the network high-speed terminal.

The application layer behavior corresponds to at least one of:

Example 4, on the basis of any of the foregoing examples 1 to 3, this example specifies a first policy:

the first policy includes: at least one network state information and an application layer behavior corresponding to each network state information.

The application layer behaviors corresponding to different network state information may be the same or different. For example, referring to table 1, taking the network state information as the QoS parameter and the relevant parameter of the application layer behavior as the coding rate as an example for explanation, when one or more values of the QoS parameter is x1 combination, the coding rate of the application layer corresponds to y 1; when one or more values of the QoS parameters are x2 combination, the coding rate of the application layer is y 2:

TABLE 1

It should be understood that table 1 is only an example, and the network status information in the actual process may not be limited to the QoS parameter, nor the relevant parameter of the application layer behavior is limited to the coding rate. The network state information may be a combination of one or more parameters, and the related parameters of the application layer behavior may also be one or more parameters, which are not exhaustive in this example.

In another case, the first policy may include: at least one first parameter, and an application layer behavior corresponding to each first parameter;

wherein each of the first parameters is used for indicating at least one network status information.

In other words, in the case where the first parameter is included in the first policy, the network state information is indicated by the first parameter. Specifically, the first parameter may be referred to as a Reference parameter. By adding the first parameter, different combinations of QoS parameters can be classified into the same first parameter, so that several first parameters are divided, and different first parameters correspond to different application layer behaviors (such as coding rate, coding format and the like), thereby being beneficial to reducing the configuration and interaction amount.

In this case, the first policy may only configure a mapping relationship between the first parameter and the application layer behavior parameter, and in such a case, the terminal only needs to receive a notification of the first parameter from the network side, so that the terminal does not need to be notified every QoS change, thereby reducing the amount of interaction.

Still alternatively, the first policy may be configured with the first parameter, network status information, and parameters related to application layer behavior. Specifically, the first policy includes at least one first parameter, each first parameter corresponds to network state information, and each first parameter corresponds to a parameter related to an application layer behavior. The application layer behaviors corresponding to different first parameters are different, and in addition, different network state information may correspond to the same first parameter.

Still further, the change of the first parameter may be directly notified to the terminal by the 3GPP network, or the terminal may map to different references (first parameters) according to the QoS parameter to query the corresponding application layer behavior.

An example of the first policy includes a first parameter, network status information, and an application layer behavior parameter, as shown in table 2 below, and is described by taking the first parameter as reference, the network status information as a QoS parameter, and the application layer behavior parameter as an encoding rate as an example:

TABLE 2

It should be understood that table 2 is only an example, and the network status information in the actual process may not be limited to the QoS parameter, nor the relevant parameter of the application layer behavior is limited to the coding rate. The network state information may be a combination of one or more parameters, and the application layer behavior related parameters may also be one or more parameters, and the combination of the network state information corresponding to different first parameters may also be not only the QoS parameter combination described above, but also other parameter combinations, which is only not exhaustive in this example.

Further, before the terminal device executes the foregoing step 21, the first policy is also acquired. The terminal equipment receives a first strategy configured by the network equipment; the network equipment is access network equipment or core network equipment;

or, the terminal device receives the first policy configured by an application server.

Specifically, the first policy may be configured to the terminal device by a network device, such as a 3GPP access network or a core network element; alternatively, the first policy may be configured to the terminal device by the application server.

When the network equipment is access network equipment, the first strategy is carried by a Radio Resource Control (RRC) message; and when the network equipment is core network equipment, the first strategy is carried by NAS information. For example, if the 3GPP network element is configured to the terminal, the core network device (e.g., PCF or SMF) may send the downlink NAS message to the terminal device. Still further, the NAS message may include a container for carrying the first policy.

In summary, a specific example of the scheme provided in this embodiment, as shown in fig. 5, may be: when the QoS of the 3GPP system is changed, the 3GPP network element directly informs the terminal (through AS layer or NAS layer signaling); the application layer of the terminal can directly sense the change of the QoS, so that the change can be rapidly adjusted according to the preset behaviors (such as different QoS corresponding to different coding rates or formats) of the application layer; the terminal informs the change situation and/or the adjusted behavior of the QoS to an application server on the network side through a user plane of the 3GPP in the form of an application data packet.

Finally, it should be noted that the present embodiment can be applied to any network state change to adjust the behavior of the application layer, and the adjustment can be performed quickly as long as the network state change is configured on the terminal. The method is suitable for services with higher QoS requirements, such as V2X, URLCC, unmanned aerial vehicles and the like, and can also be used in 4G networks or WLAN networks.

In addition, a simplified process of notifying the application server of the QoS change by the 3GPP network is provided, and the application server can have no interface with the 3GPP core network; and the existing architecture and signaling are fully used, and the influence on the existing protocol is small.

An embodiment of the present invention provides a terminal device, as shown in fig. 6, including:

a first communication unit 61 that acquires network status information; the network state information is used for the terminal equipment to determine the application layer behavior to be executed;

the first processing unit 62 stores a first policy, where the first policy is used to characterize a correspondence between network state information and application layer behavior.

An embodiment of the present invention further provides a network device, as shown in fig. 7, including:

a second communication unit 71 that transmits network status information to the terminal device;

As shown in fig. 8, an application server provided in an embodiment of the present invention includes:

the third communication unit 81 receives the changed situation of the adjusted application layer behavior and/or network status information sent by the terminal device.

The network state information contains QoS parameters. Wherein the QoS parameter includes at least one of:

5G quality of service indication 5QI, allocation and retention priority ARP, determined data stream bit rate GFBR, maximum data stream bit rate MFBR, uplink or downlink maximum packet loss rate, end-to-end PDB, AN-PDB, packet error rate, packet priority, averaging window, resource allocation type, maximum data burst capacity, UE-aggregated maximum bit rate AMBR, session-AMBR.

The application layer behavior corresponds to at least one of:

Examples 1, 1,

The method for the terminal device to obtain the network status information may be as follows: the first communication unit 61 receives network status information sent from the network device.

case 1, the network device is an access network device:

the first communication unit 61 of the terminal device receives network status information sent by an access network device, where the network status information is carried by an AS message. That is, when the network device is an access network device, the access network device directly sends the network state information to the terminal device. Here, the access network device may be a base station.

The AS message may be an RRC message.

It should be noted that, when the network state information changes, the first processing unit 62 of the terminal device adjusts the application layer behavior based on the changed network state information and the first policy to obtain the adjusted application layer behavior.

Case 2, the network device is a core network device:

the second communication unit 71 of the network device receives the network status information sent by the access network device, and sends the NAS message carrying the network status information to the terminal device.

Correspondingly, the first communication unit 61 of the terminal device receives the network state information sent by the core network device; wherein the network state information is carried by a NAS message.

The first processing unit 62 of the terminal device adjusts the coding-related parameters.

The first indication may further indicate a specific notification manner.

For example, the first indication may be used to indicate whether the network device notifies the terminal device of a change condition of the network status information; or, the network device is used to indicate whether the network device notifies the terminal device of the network status information. The difference between the two is that the former is to send the network state information to the terminal device when the network state information changes, or the change situation of the network state information; the latter is that the network device can send the network status information to the terminal device regardless of whether the network status information changes.

The network side may return, according to the first indication, a second indication through the second communication unit, where the second indication is used to indicate whether the network side supports notifying the terminal of the network status information and a notification manner supported by the network device (e.g., notifying according to an AS or NAS message). Accordingly, the first communication unit of the terminal device may receive the second indication. For example, if the second indication indicates that the network device supports notifying the terminal device of the network status information, a specific notification manner may be further obtained, for example, the notification manner supported by the network device may be AS message notification.

The terminal device may learn whether the network device supports notifying the network status information after receiving the second indication, and if so, further receive the network status information sent by the network device through the second communication unit, and the specific processing is the same as the foregoing example.

Or the first communication unit of the terminal equipment sends the first instruction to the network according to the second instruction.

After receiving the second indication, the terminal sends the first indication to the network by the first communication unit of the terminal device according to the notification whether the network supports the network state information and the specific notification mode supported by the network device. The network device is informed whether to inform the network state information through the first indication, and in addition, the network device can be informed of the informing mode adopted through the first indication.

Examples 2,

Based on the terminal device provided in example 1, obtaining network status information, and in a case that the network status information changes, after adjusting the application layer behavior to obtain an adjusted application layer behavior, the processing of the terminal device further includes:

the first communication unit 61 of the terminal device sends the adjusted change condition of the application layer behavior and/or the network state information to the application server.

Accordingly, the processing of the application server may include: the third communication unit 81 of the application server receives the adjusted behavior of the application layer and/or the change of the network status information sent from the terminal device.

Examples 3,

the first communication unit 61 of the terminal equipment acquires the change situation of the configured predicted network state information;

wherein, the predicted change situation of the network state information comprises: and predicting different network state information corresponding to the terminal equipment in different areas and/or time.

The first processing unit 62 of the terminal device determines the corresponding network state information according to the current area and/or time of the terminal device based on the predicted change condition of the network state information.

The application layer behaviors corresponding to different network state information may be the same or different.

The terminal device also obtains a first policy. A first communication unit 61 of the terminal equipment receives a first policy configured by network equipment; the network equipment is access network equipment or core network equipment;

alternatively, the first policy configured by an application server is received.

In addition, a simplified procedure for notifying the application server of the change of the QoS in the 3GPP network is provided, and the application server can have no interface with the 3 GPP; and the existing architecture and signaling are fully used, and the influence on the existing protocol is small.
