The scheme provided by the embodiment of the application relates to a QoS calling technology based on hybrid networking in mobile communication. It is understood that the hybrid networking technology is a hybrid network construction technology including two subscription network modalities. For example, the hybrid network may be a hybrid network including a 2G (second generation mobile communication technology) network and a 3G (third generation mobile communication technology) network, may be a hybrid network including a 3G network and a 4G (fourth generation mobile communication technology) network, may be a hybrid network including a 4G network and a 5G (fifth generation mobile communication technology) network, and may also be a hybrid network including any two future mobile network modalities, such as a 5G network and a 6G (sixth generation mobile communication technology) network, with the advance of network technology, which is not limited in this embodiment. Under the mixed networking, the QoS platform simultaneously interfaces the core networks of the two signed network forms, QoS service of the two signed network forms is simultaneously realized, and interaction can be carried out between the core networks of the two signed network forms. It should be understood that the hybrid networking technology may also be a hybrid network building technology including multiple subscription network forms, and the QoS platform simultaneously interfaces with core networks to which the multiple subscription network forms belong, and simultaneously implements QoS services of the multiple subscription network forms, which is not limited in this embodiment.

The QoS platform may be deployed on a network open function nef (network Exposure function), a capability open access platform af (application function), or other network component entities.

Fig. 1 is a schematic diagram of a networking architecture of a QoS platform convergence intensive deployment according to an exemplary embodiment of the present application. As can be seen from the networking architecture for QoS platform convergence intensive deployment shown in fig. 1, in a hybrid networking including a 4G network and a 5G network, a QoS platform interfaces with a 4G core network and a 5G core network at the same time, and interacts with a network element of the 4G core network through a diameter protocol interface and interacts with a network element of the 5G core network through an HTTP2 protocol interface.

It should be understood that the user equipment in the 4G network is 4G user equipment, and the 4G user equipment is accessed to the 4G core network; the user equipment under the 5G network is 5G user equipment, and the 5G user equipment is accessed to a 5G core network. The 4G user equipment accesses the QoS platform through the 4G wireless signals, the 5G user equipment accesses the QoS platform through the 5G wireless signals in a scene with 5G wireless signals, and the 5G user equipment can also access the QoS platform through the 4G wireless signals in a scene without the 5G wireless signals.

The network elements of the 4G core network comprise one or more of the following: mobility Management entity mme (mobility Management entity), service gateway sgw (serving Gate way), PDN gateway pgw (PDN Gate way), policy and Charging Rules function pcrf (policy and Charging Rules function), home Subscriber server hss (home Subscriber server), base station (enb evolved Node b). Pdn (public Data network) is a public Data network and a communication network providing Data communication services to the public. The system consists of a switch, a network control center, user home equipment, a communication line and other facilities. Each network-accessing subscriber can communicate with other subscribers on the network, and the public data network is responsible for transparent error-free transmission of data therebetween.

Wherein, the network element of the 5G core network comprises one or more of the following: network storage function nrf (nf replication function), user Plane function upf (user Plane function), radio Access network ran (radio Access network), network open function NEF, policy Control function pcf (policy Control function), unified Data Management udm (unified Data manager), Access and Mobility Management function amf (Access and Mobility Management function), session Management function smf (session Management function).

The PCRF network element of the 4G core network can interact with the PCF network element of the 5G core network, the AF directly interacts with the PCRF network element of the 4G in a 4G mode, the PCRF network element interacts with the PCF network element, and the interaction between the AF and the PCF network element is indirectly realized, so that the QoS service of the 5G is realized.

Illustratively, the QoS platform and the PCRF of the 4G core network establish an Rx session based on a diameter protocol, issue a QoS securing policy to the 4G core network through the Rx session, the 4G core network triggers to establish a dedicated bearer corresponding to the QoS, and the dedicated bearer executes the QoS securing policy issued by the core network on the wireless side, thereby implementing the QoS differentiated service of the 4G network.

Illustratively, the QoS platform establishes an N5 session based on the HTTP2 protocol with the PCF of the 5G core network, issues a QoS securing policy to the 5G core network through the N5 session, the 5G core network triggers the establishment of a QoS flow corresponding to the QoS securing policy, and executes the corresponding QoS securing policy on the wireless side, thereby implementing differentiated services of the 5G network.

The networking architecture for the QoS platform convergence intensive deployment shown in this embodiment effectively improves the problem of routing addressing of the QoS platform to the home core network element, and for 4G user equipment, the QoS platform addresses the PCRF network element of the 4G core network to which the user equipment belongs through a number segment in the user equipment number; for 5G user equipment, the QoS platform carries a SUPI (Subscription Permanent Identifier) Identifier to identify a PCF network element of a home 5G core network of the user equipment through a network function entity with an addressing function. The method not only solves the routing and network element addressing problems of the QoS platform in the process of executing the issuing of the QoS guarantee strategy, but also helps the QoS platform shield 4/5G network layer interface protocol.

Based on the hybrid networking, embodiments of the present application respectively provide a QoS invoking method based on hybrid networking, a QoS invoking apparatus based on hybrid networking, an electronic device, a computer-readable storage medium, and a computer program product, which will be described in detail below.

Referring to fig. 2, fig. 2 is a flowchart illustrating a QoS invocation method based on hybrid networking according to an exemplary embodiment of the present application. The method can be applied to an implementation environment of a networking architecture containing the QoS platform convergence intensive deployment shown in fig. 1 and executed by a QoS platform in the networking architecture. It should be understood that the method may be applied to other exemplary implementation environments and is specifically executed by devices in other implementation environments, and the embodiment does not limit the implementation environment to which the method is applied.

In an exemplary embodiment, the QoS invocation method based on hybrid networking at least includes steps S110 to S170, which are described in detail as follows:

step S110, responding to a token acquisition request from the user equipment, generating a token carrying user network identification information, and sending the encrypted token to the user equipment.

The user equipment may be an electronic device having a network connection function, such as a smart phone, a vehicle-mounted computer, a tablet computer, a notebook computer, or a computer, but is not limited thereto. The user equipment may communicate with the converged QoS platform through wireless networks such as 3G, 4G, and 5G, which is not limited herein.

The token is a mark or a secret number for identity authentication between the user equipment and the QoS platform, the user equipment sends a request to the QoS platform in a certain mode, the QoS platform sends the request to the user equipment, and the user equipment accesses, views or operates resources of the QoS platform by using the token.

The user network identification information contains the signing network form of the user equipment, and the user equipment cannot know the signing network form of the user equipment, so that the QoS platform places the signing network form of the user equipment in the user network identification information of the token and sends the signing network form of the user equipment to the user equipment, and the user equipment can know the signing network form of the user equipment according to the user network identification information conveniently.

Step S130, receiving a QoS guarantee request from the user equipment, where the QoS guarantee request carries the encrypted token and the bandwidth information to be guaranteed.

The QoS guarantee request is information returned to the QoS platform by the user equipment after receiving the encrypted token sent by the QoS platform, and is used for requesting the QoS guarantee of the stable bandwidth from the QoS platform, so that the user equipment can conveniently perform scenes such as outdoor live broadcast or video playing.

It should be noted that the QoS related parameters include at least one of the following: service Data Flow sdf (service Data Flow), guaranteed minimum bandwidth gbr (guaranteed Flow Bit rate), maximum bandwidth mbr (max Bit rate), QoS Class identifier qci (QoS Class identifier), allocation and Retention priority function parameter arp (allocation and Retention priority).

Based on the QoS related parameters, the bandwidth information to be guaranteed in this embodiment includes one or more of GBR, MBR, QCI, and ARP, which is not limited herein.

And S150, responding to the QoS guarantee request, decrypting the encrypted token to obtain the token, and identifying the signed network form of the user equipment according to the user network identification information carried in the token.

The user network identification information is generated according to the signing network form identification and carries the signing network form identification. If the user equipment is determined to be 4G user equipment according to the signing network form identification inserted into the core network, the user network identification information generated by the QoS platform carries the 4G network identification; and if the user equipment is determined to be 5G user equipment according to the signing network form identifier inserted into the core network, carrying the 5G network identifier by the user network identifier information generated by the QoS platform. The QoS platform can confirm the signed network form of the user equipment according to the signed network form identification contained in the user network identification information.

The contracted network modalities of the user equipment comprise a 4G network and a 5G network. Because the 4G user equipment can only access the 4G core network, and the 5G user equipment only accesses the 5G core network, the QoS platform can judge whether the user equipment is accessed to the 4G core network or the 5G core network according to the signed network form identifier, thereby judging the signed network form of the user equipment, namely whether the user equipment is the 4G user equipment or the 5G user equipment.

The signed network form identifier comprises a 4G network identifier and a 5G network identifier. The signing network form mark is a mark inserted by the core network executing the head enhancing action when the message information of the token request sent by the user equipment passes through the core network, and the core network transmits the message information to the QoS platform after executing the head enhancing action. And the QoS platform receives the message information sent by the core network, generates user network identification information carried in the token according to the signing network form identification, generates the token carrying the user network identification information, encrypts the token, and sends the encrypted token to the user equipment. The QoS platform can judge whether the user equipment is 4G user equipment or 5G user equipment according to the signing network form identification, and is convenient for generating corresponding user network identification information according to the signing network form identification.

And step S170, performing QoS guarantee response on the broadband information needing to be guaranteed according to the signed network form obtained by identification.

When the signed network form of the user equipment is a 4G network, the signed network form obtained by identification is the 4G user equipment, and at the moment, the process of carrying out QoS guarantee response on the broadband information needing to be guaranteed according to the signed network form obtained by identification comprises the following steps: the QoS platform addresses a PCRF network element in a 4G core network to which the user equipment belongs according to a number segment in the number of the user equipment, and initiates an AAR guarantee request to the PCRF network element; after receiving the AAR guarantee return code of the PCRF network element according to the AAR guarantee request, the QoS platform issues a QoS guarantee strategy and/or a QoS guarantee return code to the user equipment according to the AAR guarantee return code.

Illustratively, the QoS platform addresses a PCRF network element of a 4G core network to which the user equipment belongs according to an H code in the number of the user equipment, where the H code is a number segment in the number of the user equipment and can distinguish the province and the region to which the user equipment belongs. For example, if the user equipment is a mobile phone, the number of the user equipment is a mobile phone number, the mobile phone number is usually 11 bits, the first seven bits are H-codes, which is also called a mobile phone number segment, wherein the 1 st to 3 th bits are network identification numbers, and the 4 th to 7 th bits are area codes, and the location of the mobile phone number can be queried through the 4 th to 7 th bits of the H-codes, for example, which province and which city the mobile phone number belongs to.

The AAR guarantee is a guarantee interface provided by a PCRF network element in the 4G core network for the QoS platform, and the QoS platform can issue a QoS guarantee strategy of a user to the 4G core network through the guarantee interface.

The method comprises the steps of an AAR guarantee request, a request for providing a guarantee interface and sent to a PCRF network element by a QoS platform, and an AAR guarantee request sent to the PCRF network element by an AF of the QoS platform through an Rx interface.

And the PCRF network element responds to the AAR guarantee request, establishes a special bearer of the bandwidth information, namely establishes a guarantee interface for bearing a QoS guarantee strategy of the user equipment, and sends the AAR guarantee return code to the QoS platform after the establishment is finished. Referring to fig. 3, fig. 3 is a schematic diagram of a unified scheduling interface and a unified return code called by 4/5G network QoS according to an exemplary embodiment of the present application, and as shown in fig. 3, if a guarantee interface is successfully created, a corresponding AAR guarantee return code is a character string 2001; if the policy is not authorized, the corresponding AAR guarantee return code is string 5003; if the session does not exist, the corresponding AAR guarantee return code is string 5065.

And the QoS guarantee return code is set in one-to-one correspondence with the AAR guarantee return code. After receiving the AAR guarantee return code sent by the PCRF network element, the QoS platform determines whether to issue a QoS guarantee strategy to the user equipment according to the AAR guarantee return code, and/or sends the QoS guarantee return code to the user equipment according to the AAR guarantee return code, and the user can know whether the user equipment successfully calls the QoS capability according to the QoS guarantee return code. As shown in fig. 3, if the AAR guarantee return code is the character string 2001, the corresponding QoS guarantee return code is "0, successful", which indicates that the QoS guarantee policy is successfully issued to the user equipment; if the AAR guarantee return code is the string 5003, the corresponding QoS guarantee return code is "130, the policy is not authorized"; if the AAR guarantee return code is the string 5065, the corresponding QoS guarantee return code is "131, and the user does not exist".

When the signed network form of the user equipment is a 5G network, the signed network form obtained by identification is the 5G user equipment, and at the moment, the process of carrying out QoS guarantee response on the broadband information needing to be guaranteed according to the signed network form obtained by identification comprises the following steps: the QoS platform carries an SUPI identifier, addresses a PCF network element in a 5G core network to which the user equipment belongs according to the SUPI identifier through a network functional entity with an addressing function, and sends a service request for establishing a strategy issuing interface to the obtained PCF; and after receiving the service guarantee return code returned by the PCF network element according to the service request, the QoS platform issues a QoS guarantee strategy and/or a QoS guarantee return code to the user equipment according to the service guarantee return code.

Illustratively, the QoS platform carries the SUPI identifier, and the PCF network element of the home 5G network of the user equipment is addressed according to the SUPI identifier through the HNRF of the large area.

The large-area HNRF is a network functional entity deployed in a large area and has an addressing function for discovering other network functional entities.

Illustratively, the QoS flow of the GBR is established to carry traffic requested for QoS provisioning of the user equipment.

GBR, guaranteed bit rate, GBR only applies to GBR bearers, guaranteed bit rate is provided to GBR bearers, and traffic of GBR bearers includes voice, streaming media, real-time games, and the like.

The service request for creating the policy issuing interface includes an Npcf policy authorization (Npcf _ PolicyAuthorization) service request, where Npcf _ PolicyAuthorization is a policy issuing interface provided by a PCF network element in a 5G core network for the QoS platform, and the QoS platform may issue the QoS guarantee policy of the user to the core network through the policy issuing interface. The Npcf _ PolicyAuthorization service request is a service request for creating a policy issuing interface sent by the QoS platform to the PCF network element, and for the 5G user equipment, the created policy issuing interface is an N5 interface of 5G, and is used for bearing a QoS guarantee policy of the user equipment.

And the PCF network element responds to the service request of the creation strategy issuing interface, establishes a special bearer of bandwidth information, namely, the creation strategy issuing interface is used for bearing a QoS guarantee strategy of the user equipment, and after the creation is finished, the PCF network element sends the service guarantee return code to the QoS platform. Fig. 4 is a schematic diagram of a unified scheduling interface and a unified return code for 4/5G network QoS invocation according to an exemplary embodiment of the present application, and as shown in fig. 3, if a policy issuing interface is successfully created, a corresponding service guarantee return code is a character string 201; if the policy is not authorized, the corresponding service guarantee return code is a character string 403; if the session does not exist, the corresponding service provisioning return code is the character string 404.

And after receiving the service guarantee return code sent by the PCF network element, the QoS platform determines whether to issue a QoS guarantee strategy to the user equipment according to the service guarantee return code, and/or sends the QoS guarantee return code to the user equipment according to the AAR guarantee return code, and the user can know whether the user equipment successfully calls the QoS capability according to the QoS guarantee return code. The QoS guarantee return code and the service guarantee return code are arranged in a one-to-one correspondence mode. As shown in fig. 3, if the service guarantee return code is a character string 201, the corresponding QoS guarantee return code is "0, successful", which indicates that the QoS guarantee policy is successfully issued to the user equipment; if the service guarantee return code is the character string 403, the corresponding QoS guarantee return code is "130, the policy is not authorized"; if the service guarantee return code is the character string 404, the corresponding QoS guarantee return code is "131, and the user does not exist".

As can be seen from the above, in the technical solution provided in the embodiment of the present application, under the condition that the signed network form of the user equipment is unknown, the QoS platform generates a token carrying user network identification information according to the token acquisition request of the user equipment, and subsequently, when performing QoS provisioning, only the QoS platform needs to identify the signed network form of the user equipment through the user network identification information carried in the token, and then, according to the obtained signed network form, performs QoS provisioning response on the broadband information that needs to be provisioned for the user equipment. The third-party application is not needed to distinguish the signed network form of the user, the uniform scheduling interface is used for directly calling the QoS capability, and the QoS capability guarantee service of stable bandwidth is greatly improved under the condition that the signed network form of the user equipment is unknown. That is, according to the technical scheme of the embodiment of the application, the opening of the QoS capabilities of the 2C and the 2B can be realized without depending on the signed network form of the user equipment, the QoS capability guarantee service with low time delay or stable bandwidth is provided for the user equipment, and the problem that the QoS capabilities cannot be deployed and uniformly invoked based on 4/5G fusion in the current industry standard is effectively solved. In addition, in the technical solution provided in the embodiment of the present application, when the QoS guarantee response is performed on the broadband information to be guaranteed according to the subscription network form of the user equipment, the QoS capability invocation does not require a third party to distinguish the subscription network form of the user by using a uniform scheduling interface and a uniform return code, and the QoS capability invocation can be implemented by using a uniform interface for all subscription network forms across the country. In addition, the technical scheme provided by the embodiment enables a third party to directly call the QoS capability of the QoS platform by using a nationwide uniform scheduling interface without distinguishing the signed network form identifier of the user equipment, and can fully exert the network advantages and values of the QoS platform.

In another exemplary embodiment, based on the embodiment shown in fig. 2, the QoS calling method further includes a step S100 executed before the step S110, which is described in detail as follows:

step S100, a QoS platform receives message information sent by a core network, wherein the message information contains a token acquisition request initiated by user equipment and a signed network form identifier inserted by the core network to execute a head enhancing action, and the signed network form identifier is used for generating user network identification information carried in a token.

The header enhancement action is an action performed by the core network to insert a subscription network profile identifier.

Illustratively, when the core network is a 4G core network, the header enhancement action is an operation performed by a PGW gateway in the 4G core network to insert a 4G network identity.

It can be understood that the 4G network identifier is a judgment basis for the QoS platform to judge that the user equipment is the 4G user equipment, and the QoS platform can identify that the user equipment is the 4G user equipment accessed from the 4G core network according to the 4G network identifier. And when the message information of the token acquisition request initiated by the user equipment passes through a PGW gateway of the 4G core network, the PGW gateway executes a head enhancement action and inserts the head enhancement action into the 4G network identifier.

Illustratively, when the core network is a 5G core network, the header enhancement action is an operation performed by a UPF gateway in the 5G core network to insert a 5G network identity.

It can be understood that the 5G network identifier is a judgment basis for the QoS platform to judge that the user equipment is the 5G user equipment, and the QoS platform identifies that the user equipment is the 5G user equipment according to the 5G network identifier.

The signed network form identifier is a judgment basis for judging whether the user equipment is 4G user equipment or 5G user equipment by the QoS platform, directly influences the signed network form judgment of the user equipment, and plays a key role in calling the QoS capability of the user equipment. Therefore, in order to facilitate accurate determination of the signed network form identifier, the embodiment provides an HTTP/HTTPs header enhancement insertion policy, where the HTTP/HTTPs header enhancement insertion policy includes: when the message information of the token acquisition request of the user equipment passes through the core network, the core network executes the head enhancement action and inserts the X-RAT-Type mark.

The 4G core network and the 5G core network can both execute a header enhancement action of inserting the X-RAT-Type mark, for 4G user equipment of 4G wireless access, the X-RAT-Type mark of the core network executing the header enhancement action insertion is a 4G network identification, and for 5G user equipment of 4G wireless access or 5G wireless access, the X-RAT-Type mark of the core network executing the header enhancement action insertion is a 5G network identification.

Illustratively, if the 4G user equipment is wirelessly accessed through 4G, when the 4G core network performs a header enhancement action of inserting an X-RAT-Type flag, inserting an X-RAT-Type identifier by a PGW gateway in the 4G core network, where the inserted X-RAT-Type identifier is X-RAT-Type: EUTRAN; if the 5G user equipment is accessed wirelessly through 4G, when the 5G core network executes the head enhancement action of inserting the X-RAT-Type mark, the UPF gateway in the 5G core network executes the insertion of the X-RAT-Type mark, and the inserted X-RAT-Type mark is X-RAT-Type, namely EUTRAN; and if the 5G user is accessed through the 5G wireless network, when the 5G core network executes the head enhancement action of inserting the X-RAT-Type mark, the UPF gateway in the 5G core network executes the insertion of the X-RAT-Type mark, and the inserted X-RAT-Type mark is X-RAT-Type: NR. The user can be determined to be in 4G wireless access or 5G wireless access through the X-RAT-Type mark, and the judging mode comprises the following steps: if the X-RAT-Type is marked as EUTRAN, determining that the user equipment is 4G wireless access; and if the X-RAT-Type mark is NR, determining that the user equipment is 5G wireless access.

Based on the situation, when the QoS platform receives the message information with the X-RAT-Type, if the signing network form identifier carried in the message information is the X-RAT-Type: NR, it may be determined that the user equipment is a 5G user equipment accessed through a 5G radio access, and thus, the user equipment is determined to be a 5G core network accessed 5G user equipment. The QoS platform identifies the Type of the X-RAT-Type according to the signing network form carried in the message information: and the NR generates a token carrying user network identification information, and sends the encrypted token to the user equipment, wherein the user network identification information carried by the token is an X-RAT-Type for inserting the head enhancement action of the core network: NR, facilitating the QoS platform to select the 4G route to execute the QoS guarantee strategy when responding to the QoS guarantee request of the user equipment; if the signing network form identifier carried in the message information is X-RAT-Type: EUTRAN, at this time, it may be determined that the user equipment is accessed through 4G radio, may be 4G user equipment accessed through 4G radio, and may also be 5G user equipment accessed through 4G radio, and at this time, it is impossible to determine a network access state of the user equipment, where the network access state of the user equipment refers to whether the user equipment is accessed through a 4G core network or a 5G core network. Therefore, it is impossible to distinguish whether the ue is a 4G ue or a 5G ue, so that the corresponding route cannot be accurately selected in the subsequent steps to execute the QoS guarantee policy.

Therefore, the signed network form of the user equipment cannot be judged by the X-RAT-Type mark alone, and whether the user equipment is the 4G user equipment or the 5G user equipment cannot be distinguished. In order to solve the problem, it is convenient to determine whether the user equipment is a 4G core network access or a 5G core network access according to the signed network form identifier, so as to determine whether the user equipment is a 4G user equipment or a 5G user equipment, and this embodiment further provides a 5G header enhancement insertion policy, where the 5G header enhancement insertion policy includes: in the SMF/UPF header enhancement setting of 5G, a 5G network identifier which can be inserted by a 5G core network when the header enhancement action is executed is added: the X-APN-DNN label, i.e. the inserted 5G network identity performed by the UPF gateway, also comprises the X-APN-DNN label. And the X-APN-DNN mark is a network identifier special for the 5G core network, and when a message initiated by the user equipment and used for acquiring the token request passes through the UPF gateway of the 5G core network, the UPF gateway executes head enhancement and inserts the X-APN-DNN mark. Illustratively, the format of the X-APN-DNN tag is X-APN-DNN: because the X-APN-DNN mark is specific to the 5G core network, when the QoS platform receives the message information with the X-APN-DNN mark, the CTNET judges that the user equipment is a 5G user accessed through the 5G core network, and the QoS platform identifies the X-APN-DNN according to the 5G network: the CTNET generates a token carrying user network identification information, and sends the encrypted token to user equipment, wherein the user network identification information carried by the token is a 5G network identification X-APN-DNN for inserting a core network execution head enhancement action: CTNET. The QoS platform is convenient to select a route of 5G to execute the QoS guarantee strategy when responding to the QoS guarantee request of the user equipment.

For example, if the 5G user equipment is wirelessly accessed through 4G, the 5G core network performs the insertion of the X-APN-DNN by the UPF gateway in the 5G core network while performing the header enhancement action of inserting the X-APN-DNN tag: CTNET; if the 5G user is accessed wirelessly through 5G, when the 5G core network executes the head enhancement action of inserting the X-APN-DNN mark, the UPF gateway in the 5G core network executes the insertion of the X-APN-DNN: CTNET.

It can be understood that the execution sequence of the HTTP/HTTPs header enhancement insertion policy and the 5G header enhancement insertion policy may be exchanged, and the QoS platform may not be affected to determine whether the user equipment is a 4G user equipment or a 5G user equipment according to the subscription network form identifier. For example, if the 5G user equipment is accessed through the 4G radio, the 5G core network may first perform HTTP/HTTPs header enhancement insertion policy insertion X-RAT-Type: EUTRAN, post-enforcement 5G header enhancement insertion policy insertion X-APN-DNN: CTNET; or, the 5G core network may first perform 5G header enhancement insertion policy insertion X-APN-DNN: CTNET, then, executing HTTP/HTTPS head enhancement insertion strategy to insert X-RAT-Type: EUTRAN.

When the QoS platform judges according to the signed network form identifier, if the signed network form identifier contains X-RAT-Type: the EUTRAN mark and the X-APN-DNN mark can determine that the user equipment is 5G user equipment accessed for 4G wireless; if the signed network form identifier does not contain the X-APN-DNN mark, determining that the user equipment is 4G user equipment with 4G wireless access; if the signing network form mark contains X-RAT-Type: NR and X-APN-DNN labels, it can be determined that the user equipment passes 5G user equipment for 5G wireless access.

As can be seen from the above, in the method provided in this embodiment, when the core network executes the header enhancement action, the HTTP/HTTPs header enhancement insertion policy and the 5G header enhancement insertion policy are adopted to insert the signed network form identifier in the message information, and then the message information is sent to the QoS platform, and the QoS platform can accurately determine the signed network form of the user equipment according to the signed network form identifier without a third-party application distinguishing the signed network form of the user equipment. The mode of setting the signing network form identifier shortens the identification process of the QoS platform to the signing network form of the user equipment, and improves the accuracy and efficiency of QoS capability calling to a great extent.

Referring to fig. 4, fig. 4 is a flow chart illustrating a QoS invocation interaction based on hybrid networking according to an exemplary application scenario of the present application. As shown in fig. 4, the interaction process is described in detail as follows:

the user equipment initiates a QoS business process and sends a token acquisition request to the QoS platform.

When the message information of the token acquisition request passes through the core network, the core network executes the head enhancing action to insert the signing network form identification into the message information, and after the head enhancing action is executed, the message information is sent to the QoS platform.

The QoS platform receives message information sent by a core network, the message information contains a token acquisition request initiated by user equipment, the QoS platform responds to the token acquisition request from the user equipment, generates a token carrying user network identification information, and sends the encrypted token to the user equipment.

And after receiving the encrypted token, the user equipment sends a QoS guarantee request to the QoS platform, wherein the QoS guarantee request carries the encrypted token and the bandwidth information to be guaranteed.

The QoS platform receives and responds to a QoS guarantee request of the user equipment, decrypts the encrypted token to obtain the token, and identifies the signing network form of the user equipment according to the user network identification information carried in the token; and the QoS platform performs QoS guarantee response on the broadband information needing guarantee according to the signed network form obtained by identification.

As can be seen from the above, in the method provided in this embodiment, the QoS platform, the 4G core network, the 5G core network, and the user equipment interact with each other through the network, and the QoS capability invocation is implemented when the signed network form of the user equipment is unknown.
