Description

Parameter determination method, communication device and storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to a parameter determining method, a communication apparatus, and a storage medium.

Background

In an Evolved Packet System (EPS) network, in order to realize control of quality of service (QoS) of a service, a QoS control mechanism based on an EPS bearer is proposed. The EPS bearer may be divided into a Guaranteed Bit Rate (GBR) bearer and a Non-guaranteed bit rate (Non-GBR) bearer: for each GBR bearer, the control of the bandwidth is based on a Maximum Bit Rate (MBR) parameter. For Non-GBR bearers, in order to limit bandwidth, an Aggregate Maximum Bit Rate (AMBR) concept is proposed, and the AMBR may be divided into an Access Point Name (APN) AMBR and a User Equipment (UE) AMBR. Wherein the APN-AMBR parameter is used to identify a maximum bandwidth of all Non-GBR bearers on one or more Packet Data Network (PDN) connections. In the downlink direction, the APN-AMBR parameters are controlled by a packet data gateway (PGW).

The APN-AMBR parameter signed by the terminal is stored in the home subscriber server (HSS +). After the terminal accesses the EPS network, the data transmission capability of the core network and the base station in the EPS network is weak, so that the terminal can use a smaller APN-AMBR parameter in the EPS network. With the development of a 5G access network, a scenario of a mixed networking of a 4G network and a 5G access network may occur, and after a terminal is switched from the 4G network to the 5G access network, because the HSS + stores a smaller signed APN-AMBR parameter, although the terminal is switched from the 4G network with a lower data transmission capability to the 5G access network with a higher data transmission capability, the terminal still uses the signed APN-AMBR parameter in the 4G network, that is, the terminal still uses a bandwidth in the 4G network in the switched 5G access network, so that the bandwidth is still smaller, and the advantage of the 5G access network cannot be effectively embodied.

Disclosure of Invention

The application provides a parameter determination method, a communication device and a storage medium, so as to realize that APN-AMBR parameters used by a terminal are matched with network capability accessed by the terminal.

In a first aspect, the present application provides a parameter determining method, including determining a type of a first access network to which a terminal is currently accessed, and configuring an APN-AMBR parameter for controlling a maximum bandwidth carried by a Non-guaranteed bit rate Non-GBR of the terminal as a first APN-AMBR parameter corresponding to the type of the first access network, where different types of access networks correspond to different APN-AMBR parameters.

Based on the scheme, after the type of the first access network to which the terminal is currently accessed is determined, the APN-AMBR parameter is configured to be the first APN-AMBR parameter corresponding to the type of the first access network, so that the maximum bandwidth of the Non-guaranteed bit rate Non-GBR bearer used by the terminal can be matched with the capability of the access network to which the terminal is currently accessed.

In a possible implementation manner, when the terminal is switched to access the first access network from the second access network, the type of the first access network is determined, and a second APN-AMBR parameter currently used for controlling a maximum bandwidth of a Non-GBR bearer of the terminal is modified into a first APN-AMBR parameter corresponding to the type of the first access network, where the second APN-AMBR parameter is an APN-AMBR parameter corresponding to the type of the second access network. Therefore, the APN-AMBR parameters used by the terminal can be matched with the current access network capability accessed by the terminal by triggering and modifying the APN-AMBR parameters in time.

Two implementations of configuring the APN-AMBR parameter as a first APN-AMBR parameter corresponding to a type of the first access network are provided as follows.

In a possible implementation manner, when it is determined that the terminal is switched to access the first access network from the second access network, the target device is notified to modify an APN-AMBR parameter, which is currently used for controlling a maximum bandwidth carried by the terminal Non-GBR, from the second APN-AMBR parameter to a first APN-AMBR parameter corresponding to the type of the first access network, where the second APN-AMBR is an APN-AMBR parameter corresponding to the type of the second access network. When the terminal is determined to be switched to access the first access network from the second access network, the target device is informed to modify the current APN-AMBR parameter from the second APN-AMBR to the first APN-AMBR, and the second APN-AMBR corresponds to the type of the second access network because the first APN-AMBR corresponds to the type of the first access network, so that the APN-AMBR used by the terminal can be matched with the network capacity accessed by the terminal by triggering and modifying the APN-AMBR parameter in time.

Detailed Description

Fig. 1a illustrates a hybrid networking system architecture diagram of a Long Term Evolution (LTE) network and a Non-independent Networking (NAS) network. As shown in fig. 1a, the system architecture includes HSS +, Mobility Management Entity (MME), MME +, PGW, Serving Gateway (SGW). The core network elements of the system are all core network elements in an LTE network. The access network may be an evolved UMTS terrestrial radio access network (E-UTRAN) of a fourth generation access network evolution, or may be a 5G radio access network 5G-RAN, and the terminal may access the MME in the core network through the E-UTRAN, or may access the SGW in the core network through the 5G-RAN.

The HSS + is mainly used to store user subscription data, such as APN-AMBR parameters, located in the home network of the user subscription.

The MME and MME + are mainly used for performing mobility management, EPS bearer control, and the like on a user, for example, functions of session management such as location registration and temporary identity allocation, handover in a CONNECT state, PDN connection, bearer maintenance, creation, modification, deletion, and the like. Wherein, MME + also adds NAS function compared with MME.

The SGW is mainly used for user plane bearer from a terminal to a core network, data caching in an idle mode of the terminal, a function of initiating a service request at a network side, and functions of lawful interception, packet data routing and forwarding. The SGW is a device that connects Radio Access Networks (RANs) of different third Generation Partnership Project (3 GPP), and is an anchor point of a user plane in the 3GPP system (i.e., when a user accesses from different access networks, service data passes through the SGW), and one user can only have one SGW at one time. In scenarios of handover between different RATs (including fallback), the SGW is unchanged. For example, when a terminal switches between different radio access network types of 3GPP, such as between NR and LTE networks (Inter-RAT handover), both eNB and MME may change, but the SGW does not change.

The PGW is responsible for allocating user IP addresses, charging functions, packet filtering, policy control, and other functions, and is a mobility anchor point of a 3GPP access network, and a user can access multiple PGWs at the same time.

The interface between the HSS + and the MME is an interface S6a, and the interface S6a is mainly used for functions of user access authentication, user subscription data insertion, user access PDN authorization, authentication of a mobility management message of a user when interconnected with a non-3 GPP system, and the like. The interface between the MME and the E-UTRAN is the S1-MME interface, i.e. the interface between the evolved base station eNodeB and the MME, for transferring user data and corresponding user plane control frames. The interface between the PGW and the SGW is an S5/S8 interface, and can be divided into a control plane and a user plane. The S5 interface is an interface between the SGW and the PGW within the network. The interface should be able to provide the function of SGW relocation during user mobility under the condition of SGW and PGW separation. S8 is an interface between an SGW and a PGW of a Public Land Mobile Network (PLMN), and should have an S5 interface function in a roaming case. The interface between the SGW and the 5G-RAN and the interface between the SGW and the E-UTRAN are both S1-U interfaces, i.e. interfaces between enodebs and SGW, which are used to carry user plane tunnels and path switching between enodebs during handover. The interface between the MME and the MME + is an S10 interface, namely a control plane interface between the MME, and is used for redistribution of the MME (or MME +) and transmission of information between the MMEs (or MME +). The interface between the SGW and the MME is an S11 interface, and is used for transmitting information such as bearer control and session control.

Fig. 1b illustrates a networking system architecture diagram of an LTE network and an NR network. As shown in FIG. 1b, the terminal accesses to the MME in the core network through the access E-UTRAN under the LTE network. The terminal accesses to the AMF in the core network through the 5G-RAN under the NR network. The core network of the LTE network is the same as that of the NR network, and the HSS + entity is merged with a Unified Data Management (UDM) entity, and is referred to as a data management entity (or referred to as an HSS +/UDM entity); the policy control entity may be a Policy Control Function (PCF) entity and a Policy and Charging Rules Function (PCRF) entity, which are functionally combined and may be collectively referred to as a policy control entity; a Session Management Function (SMF) entity and a PGW-C entity are merged and collectively called a session management entity; the UPF entity and the PGW-U entity are combined and collectively called as a user plane entity; the SGW entity can also be split into an SGW-C entity and an SGW-U entity.

The interface between the MME and the AMF is an N26 interface, and the N26 interface can realize the intercommunication between the EPC and the NG core network. The network supports an N26 interface, which is an optional direction for interworking, and an N26 interface supports the functions supported by the S10 interface in fig. 1 a.

The terminal is a device with a wireless transceiving function, can be deployed on land, and comprises an indoor or outdoor terminal, a handheld terminal or a vehicle-mounted terminal; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). The terminal device may be a mobile phone (mobile phone), a tablet computer (pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal, an Augmented Reality (AR) terminal, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned driving (self driving), a wireless terminal in remote medical treatment (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety, a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), a user equipment (user equipment, UE), and the like. The terminal can Access a 4G Access network or a 5G Access network through a wireless air interface and obtain corresponding services, and the terminal can exchange information with a base station through the air interface and exchange information with a mobility management entity of a core network through Non-Access-Stratum signaling (NAS).

It is to be understood that the above entities or functions can be network elements in a hardware device, software functions running on dedicated hardware, or virtualized functions instantiated on a platform (e.g., a cloud platform). The above-described functionality may be divided into one or more services, and further, a service entity may be present that exists independently of the network functionality.

It is to be understood that the terms "first," "second," and the like in the embodiments of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. "and/or" for describing an association relationship of associated objects, indicating that there may be three relationships, e.g., "a and/or B" may indicate: only A, only B and both A and B are present, wherein A and B may be singular or plural.

It should be noted that, in the embodiment of the present application, an LTE access network is also referred to as a 4G access network or an EPS network, the LTE access network is referred to as an E-UTRAN, and a core network of the LTE access network is referred to as an EPC network. The NR access network is also called a 5G access network or a 5GS network and the NR access network is called an NR-RAN or a 5G-RAN.

Fig. 2a exemplarily shows a schematic flow chart of a parameter determining method provided in the present application, and the method includes the following steps:

step 201, determining the type of a first access network currently accessed by the terminal.

In one possible implementation, the type of access network includes a 3G access network, a 4G access network, or a 5G access network. The type of the first access network may be any one of a 3G access network, a 4G access network, and a 5G access network.

Step 202, configuring an access point name-aggregated maximum bit rate APN-AMBR parameter for controlling a maximum bandwidth of a terminal Non-guaranteed bit rate Non-GBR bearer as a first APN-AMBR parameter corresponding to a type of a first access network.

And different APN-AMBR parameters corresponding to different types of access networks. For one PDU session, based on the type of each access network, one APN-AMBR parameter may be respectively corresponding, i.e. sessions of different types of access networks may have different APN-AMBR parameters.

As can be seen from steps 201 to 202, a type of a first access network currently accessed by the terminal is determined, and the APN-AMBR parameter is configured as a first APN-AMBR parameter corresponding to the type of the first access network. In this way, the maximum bandwidth of the Non-guaranteed bit rate Non-GBR bearer used by the terminal can be made to match the capability of the access network to which the terminal is currently accessing.

Further analysis and explanation are performed in combination with a specific scenario, for example, when it is determined that the type of the first access network of the terminal is an NR access network, the current APN-AMBR parameter is configured to the first APN-AMBR, so that the terminal accesses to the 5G access network and can establish a session using the APN-AMBR with the 5G bandwidth, and the advantage of the 5G access network can be fully utilized.

The method for determining the parameters is further explained with the following examples given in case one and case two in conjunction with fig. 2a above.

Situation one

In conjunction with fig. 1a, step 201 and step 202 may be performed by a PGW.

In step 201, when the terminal switches to access from the second access network to the first access network, the access network device in the first access network determines the type of the first access network of the terminal, and sends the type of the first access network to the PGW.

In step 202, the PGW may modify a second APN-AMBR parameter currently used for controlling a maximum bandwidth of a Non-GBR bearer of the terminal to a first APN-AMBR parameter corresponding to the type of the first access network, where the second APN-AMBR parameter is an APN-AMBR parameter corresponding to the type of the second access network.

For example, if the first access network is a 5G access network and the second access network is a 4G access network, the access network device in the first access network is an MME +. And if the first access network is a 4G access network and the second access network is a 5G access network, the access network equipment in the first access network is an MME.

Situation two

In conjunction with fig. 1b, step 201 and step 202 may be performed by a session management entity (SMF/PGW).

In step 201, when the terminal switches to access from the second access network to the first access network, the access network device in the first access network determines the type of the first access network of the terminal, and sends the type of the first access network to the session management entity.

And if the first access network is a 5G access network and the second access network is a 4G access network, the access network equipment in the first access network is AMF. And if the first access network is a 4G access network and the second access network is a 5G access network, the access network equipment in the first access network is an MME.

In the step 202, the session management entity may modify a second APN-AMBR parameter currently used for controlling a maximum bandwidth of a Non-GBR bearer of the terminal to a first APN-AMBR parameter corresponding to the type of the first access network, where the second APN-AMBR parameter is an APN-AMBR parameter corresponding to the type of the second access network.

Based on the above first and second cases, the above advantageous effects are further described in conjunction with specific scenarios. And if the type of the second access network is an LTE access network, the type of the first access network is an NR access network, the first APN-AMBR corresponds to the type of the first access network, and the second APN-AMBR corresponds to the type of the second access network. Because the data processing capability in the 5G access network is stronger than that in the 4G access network, usually the APN-AMBR configured in the 5G access network is larger than that configured in the 4G access network, that is, the first APN-AMBR is larger than the second APN-AMBR, when the terminal is determined to be accessed from the LTE access network to the NR access network, the current second APN-AMBR parameter is modified to be the first APN-AMBR, so that the terminal is accessed to the 5G access network, and the session can be established by using the APN-AMBR with the 5G bandwidth, that is, the advantages of the 5G access network can be fully utilized. If the type of the second access network is an NR access network and the type of the first access network is an LTE access network, it can be determined that the first APN-AMBR is smaller than the second APN-AMBR, and when it is determined that the terminal is switched from the NR access network to the LTE access network, the current parameter of the second APN-AMBR is modified into the first APN-AMBR, so that the access network connected with the terminal is a 4G access network, the provided bandwidth is smaller, and the APN-AMBR using the 4G bandwidth is modified in time, which is beneficial to avoiding the problem that the core network still transmits data to the base station at the bandwidth rate of 5G, but the terminal uses the 4G APN-AMBR for communication, and when the capability of the base station is insufficient, the problem of a large amount.

For the above step 202, the following two implementation manners are provided in the present application for configuring the APN-AMBR parameter as the first APN-AMBR parameter corresponding to the type of the first access network.

Implementation mode one

In one possible implementation manner, the type of the first access network may be sent when the access network device in the first access network receives the type of the first access network when the terminal accesses the first access network. Illustratively, the access network device of the first access network sends the type of the first access network to the PGW or the SMF/PGW. And the PGW or the SMF/PGW determines a first APN-AMBR parameter corresponding to the type of the first access network from the pre-stored association relationship between the types of different access networks and different APN-AMBR parameters, and configures the current APN-AMBR parameter as the first APN-AMBR parameter.

For example, the PGW or SMF/PGW may pre-store an association relationship between the 5G access network and the corresponding APN-AMBR parameter, an association relationship between the 4G access network and the corresponding APN-AMBR parameter, and the like.

Implementation mode two

Receiving a first APN-AMBR (access point name-average scheduling buffer) which is sent by access network equipment in a first access network and corresponds to the type of the first access network, and configuring APN-AMBR parameters which are currently used for controlling the maximum bandwidth of a Non-GBR bearer of a terminal into the received first APN-AMBR parameters.

Illustratively, the access network device of the first access network sends the first APN-AMBR parameter to the PGW or the SMF/PGW. The PGW or SMF/PGW may directly configure the current APN-AMBR parameter as the first APN-AMBR parameter.

Fig. 2b schematically illustrates a flow chart of another parameter determination method provided in the present application, where the method includes the following steps:

step 211, determining the type of the terminal accessing the first access network.

Step 220, informing the target device to configure the APN-AMBR parameter used for controlling the maximum bandwidth of the Non-guaranteed bit rate Non-GBR bearer of the terminal as a first APN-AMBR parameter corresponding to the type of the first access network.

The APN-AMBR parameters corresponding to different types of access networks are different, and the target device is a device for controlling the maximum bandwidth of a Non-GBR bearer of the terminal according to the APN-AMBR parameters.

In conjunction with fig. 1a above, the target device is a PGW. In conjunction with FIG. 1b, the target device is SMF/PGW.

In a possible implementation manner, the terminal is determined to be switched to access the first access network from the second access network, the target device is notified to modify the APN-AMBR parameter currently used for controlling the maximum bandwidth borne by the terminal Non-GBR from the second APN-AMBR parameter to the first APN-AMBR parameter corresponding to the type of the first access network, and the second APN-AMBR parameter is the APN-AMBR parameter corresponding to the type of the second access network.

Further analysis is performed by combining with a specific scenario, and if the second access network is an LTE access network and the first access network is an NR access network, the first APN-AMBR corresponds to the type of the first access network, the second APN-AMBR corresponds to the type of the second access network, because the data processing capacity in the 5G access network is stronger than that in the 4G access network, the APN-AMBR corresponding to the 5G access network is generally larger than that corresponding to the 4G access network, namely the first APN-AMBR is larger than the second APN-AMBR, when the terminal is determined to be switched from the LTE access network to the NR access network, the target device is informed to modify the current APN-AMBR parameter from the second APN-AMBR to the first APN-AMBR, therefore, the terminal accesses the 5G access network, and the APN-AMBR using the 5G bandwidth is modified to establish the session in time, so that the advantages of the 5G access network can be fully utilized. If the second access network is an NR access network and the first access network is an LTE access network, determining that the first APN-AMBR is smaller than the second APN-AMBR, and informing the target device to modify the current APN-AMBR parameter from the second APN-AMBR to the first APN-AMBR when determining that the terminal is switched from the NR access network to the LTE access network, so that the access network connected with the terminal is a 4G access network, the bandwidth provided by the access network is smaller, and the APN-AMBR using the 4G bandwidth is modified in time, which is beneficial to avoiding the problem that the terminal uses the 4G APN-AMBR to transmit data to the base station because the core network still uses the 5G bandwidth rate to communicate, and when the capability of the base station is insufficient, the problem of a large amount of downlink data packet loss.

To the above step 212, the present application provides the following two implementation manners for determining to notify the target device to modify the current APN-AMBR parameter from the second APN-AMBR parameter to the first APN-AMBR parameter.

Implementation mode one

Implementation mode two

With reference to fig. 2b, the present application takes the types of access networks including an NR access network and an LTE access network as an example. In a 4G and 5G hybrid network, due to the mobility of the terminal, the following two scenarios may occur.

In a first scenario, a terminal firstly accesses a 4G access network and then switches from the 4G access network to a 5G access network.

In this scenario, the first access network is an NR access network, and the second access network is an LTE access network.

In a second scenario, the terminal firstly accesses the 5G access network and then switches from the 5G access network to the 4G access network.

In this scenario, the first access network is an LTE access network, and the second access network is an NR access network.

The following describes the parameter determination method in detail in different situations in conjunction with the above two specific scenarios.

For scenario one, the following three scenarios are illustrated.

In case a, the above steps 211 to 212 are performed by the MME + or the AMF.

The HSS + stores the incidence relation between the first access network and the first APN-AMBR parameter and the incidence relation between the second access network and the second APN-AMBR parameter.

The parameter determination method is described in detail below with reference to fig. 1a and 1b, respectively, described above.

Case a-1, with reference to fig. 1a, the steps 211 to 212 are performed by the MME +, and the target device is the PGW.

In this case, the access network device when the terminal accesses the second access network is an MME, and the access network device when the terminal accesses the first access network is an MME +.

Fig. 3 is a schematic flow chart of another parameter determination method provided in the present application. Firstly, after the terminal accesses the 4G access network, that is, the terminal accesses the MME in the core network through the E-UTRAN, step 301 to step 302 are performed:

in step 301, the MME sends a first subscription data acquisition request to the HSS +.

Accordingly, the HSS + receives the first subscription data acquisition request from the MME.

The type of the second access network included in the first subscription data acquisition request is an LTE access network.

In step 302, the HSS + sends a first subscription response to the MME.

And the first subscription response comprises second APN-AMBR parameters corresponding to the LTE.

After the terminal is switched from the 4G access network to the 5G access network, the terminal accesses to the MME + in the core network through the 5G-RAN, and then step 303 to step 304 are performed:

step 303, the MME + sends a second subscription data acquisition request to the HSS +.

Accordingly, the HSS + receives the second subscription data acquisition request from the MME +.

The type of the first access network included in the second subscription data acquisition request is the NR access network.

In step 304, the HSS + sends a second subscription response to the MME +.

Accordingly, the MME + receives the second subscription response from the HSS +.

And the second subscription response comprises the first APN-AMBR parameter corresponding to the NR.

In the process of switching the terminal from the 4G access network to the 5G access network (inter handover), the method includes steps 305 to 307:

step 305, the MME sends the type of the second access network to the MME +.

And the type of the second access network is an LTE access network.

Accordingly, the MME + receives the type of the second access network from the MME.

In a possible implementation manner, when the MME sends the context of the terminal to the MME +, the context of the terminal includes the type of the second access network (i.e., LTE access network), and the MME + may obtain the context of the terminal from the MME through the following two implementation manners.

In the first implementation manner, when the MME determines that the terminal is switched to access to the MME +, the MME actively sends the terminal context to the MME +.

And in the second implementation mode, when the MME + determines that the terminal is accessed, the MME + sends a request for acquiring the context of the terminal to the MME, and after receiving the request for acquiring the context of the terminal, the MME + sends the context of the terminal to the MME +.

Step 306, the MME + determines that the type of the local first access network is different from the type of the second access network received from the MME, and determines that the terminal switches the type of the access from the type of the second access network to the type of the first access network.

Step 307, the MME + informs the PGW to modify the current APN-AMBR parameter from the second APN-AMBR parameter to the first APN-AMBR parameter.

As can be seen from steps 301 to 307, after the terminal accesses the 4G access network, the APN-AMBR parameter in the 4G access network is used to establish the session, so that the APN-AMBR parameter used by the terminal can be matched with the accessed network. And after the access network accessed by the terminal is changed, the MME (access network equipment accessed by the terminal before switching) sends the type of the access network accessed by the terminal to the MME + (access network equipment accessed after the terminal is switched), so that the MME + determines whether to trigger modification of the APN-AMBR parameter according to the received type of the access network and the type of the local access network, and after the terminal is switched from the 4G access network to the 5G access network, the MME + informs the PGW to modify the APN-AMBR parameter from the second APN-AMBR parameter (before switching) to the first APN-AMBR parameter (after switching).

Case a-2, in conjunction with fig. 1b above, steps 211 through 212 are performed by the AMF, and the target device is the SMF.

In this case, the access network device when the terminal accesses the second access network is an MME, and the access network device when the terminal accesses the first access network is an AMF.

And the HSS + stores the incidence relation between the first access network and the first APN-AMBR parameter and the incidence relation between the second access network and the second APN-AMBR parameter. Fig. 4 is a schematic flow chart of another parameter determination method provided by the present application. After the terminal accesses the 4G access network, that is, the terminal accesses the MME in the core network through the E-UTRAN, steps 301 to 302 in fig. 3 may be executed, and after the terminal is handed over from the 4G access network to the 5G access network, the terminal accesses the AMF in the core network through the 5G-RAN and then executes steps 401 to 403:

step 401, the AMF notifies the SMF terminal to access the first access network.

Accordingly, the terminal which is notified by the SMF receiving AMF accesses the first access network.

Step 402, the SMF sends a second subscription data acquisition request of the terminal to the HSS +/UDM.

Accordingly, the HSS +/UDM receives a second subscription data fetch request from the SMF.

And the type of the first access network included in the second subscription data acquisition request is an NR access network.

In step 403, the HSS +/UDM sends a second subscription response to the SMF.

Accordingly, the SMF receives a second subscription response from the HSS +/UDM.

And the second subscription response comprises a first APN-AMBR parameter corresponding to the NR.

In the process of switching the terminal from the 4G access network to the 5G access network (inter handover), steps 403 to 406 are performed:

in step 404, the MME sends the type of the second access network to the AMF.

Here, the type of the second access network is an LTE access network.

Accordingly, the AMF receives the type of the second access network from the MME.

In step 405, the AMF determines that the type of the local first access network is different from the received type of the second access network, and determines to switch the access from the type of the second access network to the type of the first access network.

The sequence of the above steps 401 and 404 is an example, and the steps 401 to 403 may be executed first, and then the step 404 may be executed; step 404 may be executed first, and then steps 401 to 403 may be executed.

In step 406, the AMF informs the SMF to modify the current APN-AMBR parameter from the second APN-AMBR parameter to the first APN-AMBR parameter.

In step 407, the SMF modifies the current APN-AMBR parameter from the second APN-AMBR parameter to the first APN-AMBR parameter.

As can be seen from steps 301, 302, and 401 to 407, after the terminal accesses the 4G access network, the APN-AMBR parameter establishment session in the LTE access network is used, so that the APN-AMBR parameter used by the terminal matches the network capability of the access. When Inter handover occurs, the type of the previous access network of the terminal is mutually transferred between an MME and an AMF in a core network and is used as a basis for judging whether an entity accessed by the terminal currently triggers modification of the APN-AMBR parameter, and if the modification is required to be triggered, the APN-AMBR parameter is modified in time, so that the bandwidth used by the terminal can be ensured to be matched with the network capability accessed currently. When the access is switched from the 4G access network to the 5G access network, the APN-AMBR parameters are modified in time, so that the bandwidth of the 5G access network is fully utilized.

Case B, step 211 and step 212 above are performed by HSS +/UDM.

The HSS +/UDM stores the association relationship between the first access network and the first APN-AMBR parameter and the association relationship between the second access network and the second APN-AMBR parameter. It can also be understood that the data management entity stores different APN-AMBR parameters corresponding to types of the same terminal accessing different access networks.

The parameter determination method is explained in detail below in connection with the above-described fig. 1a and 1B, respectively, for case B.

Case B-1, in conjunction with fig. 1a, the steps 211 to 212 are performed by the HSS +/UDM, and the target device is the PGW.

Fig. 5 shows another parameter determination method provided by the present application. First, after the terminal accesses the 4G access network, that is, after the terminal accesses the MME through the E-UTRAN, referring to fig. 3, the above step 301 to step 302 are performed, and after the terminal switches from the 4G access network to the 5G access network, and after the terminal accesses the MME + through the 5G-RAN, referring to step 303 to step 304 in fig. 3, in a process of switching from the 4G access network to the 5G access network (inter handover), the method may include steps 501 to 502:

step 501, the HSS + determines that the type of the first access network is different from the type of the second access network, and then determines that the terminal switches to access from the type of the second access network to the type of the first access network.

In a possible implementation manner, the type of the first access network is carried when the MME sends the first subscription data acquisition request to the HSS +, and the type of the second access network is carried when the MME sends the second subscription data acquisition request to the HSS +.

Step 502, the HSS + informs the PGW through the MME + to modify the current APN-AMBR parameter from the second APN-AMBR parameter to the first APN-AMBR parameter.

In one possible implementation, the HSS + may carry an indication in the second subscription response of step 304 that informs the PGW to modify the APN-AMBR parameter. For example, it may be an information element in the second subscription response, which may indicate a type change of the access network. It will also be appreciated that step 501 in fig. 5 may be performed between steps 303 and 304 of fig. 3, and step 502 may be omitted.

In one possible implementation, the MME + may send the first APN-AMBR parameter directly to the PGW. In another possible implementation, the MME + may send the type of the first access network to the PGW.

In step 503, the PGW modifies the current APN-AMBR parameter from the second APN-AMBR parameter to the first APN-AMBR parameter.

Based on the scheme shown in fig. 5, the data management entity issues a specific subscription APN-AMBR parameter according to the type of the access network of the terminal, so that the APN-AMBR parameter used by the terminal is matched with the network capability of the access. And the data management entity informs the PGW to modify the current APN-AMBR parameter from the second APN-AMBR parameter to the first APN-AMBR parameter according to the type of the first access network and the type of the second access network, namely after the terminal is switched from the 4G access network to the 5G access network, the APN-AMBR parameter corresponding to the NR network establishes a session when the terminal is used, so that the 5G bandwidth service can be fully utilized.

Case B-2, in conjunction with fig. 1B above, steps 211 through 212 are performed by the AMF, and the target device is the SMF.

Fig. 6 shows another parameter determination method provided by the present application. After the terminal accesses the 4G access network, that is, the terminal accesses the MME through the E-UTRAN, steps 301 to 302 in fig. 3 may be executed, and after the terminal switches from the 4G access network to the 5G access network, the terminal accesses the AMF in the core network through the 5G-RAN, and then steps 601 to 604 are executed:

step 601, the AMF informs the SMF terminal to access the first access network.

The first access network is an NR access network.

Step 602, the SMF sends a second subscription data acquisition request of the terminal to the HSS +/UDM.

In step 603, the HSS +/UDM sends a second subscription response to the SMF.

In the process of switching the terminal from the 4G access network to the 5G access network (inter handover), the method includes steps 604 to 606:

and step 604, the HSS +/UDM determines that the type of the first access network is different from that of the second access network, and then determines that the terminal is switched to access the type of the first access network from the type of the second access network.

In step 605, the HSS +/UDM informs the SMF via the AMF to modify the current APN-AMBR parameter from the second APN-AMBR parameter to the first APN-AMBR parameter.

In step 606, the SMF modifies the current APN-AMBR parameter from the second APN-AMBR parameter to the first APN-AMBR parameter.

In one possible implementation, the indication that the HSS +/UDM informs the SMF to modify the APN-AMBR parameter may be carried in the second subscription response of step 603. For example, it may be an information element in the second subscription response, which may indicate a type change of the access network. It will also be appreciated that step 603 is performed in conjunction with step 604, omitting step 605.

Based on the scheme shown in fig. 6, the data management entity issues a specific subscription APN-AMBR parameter according to the type of the access network of the terminal, so that the APN-AMBR parameter used by the terminal is matched with the network capability of the access. And the data management entity informs the SMF to modify the APN-AMBR parameter from the second APN-AMBR parameter to the first APN-AMBR parameter through the AMF according to the type of the first access network and the type of the second access network, namely after the terminal is switched from the 4G network to the 5G network, the APN-AMBR parameter corresponding to the NR network establishes a session when the terminal is used, so that the 5G bandwidth service can be fully utilized.

In case C, the above steps 211 and 212 are performed by the terminal.

The parameter determination method is described in detail below in connection with the above-described fig. 1a and 1b, respectively, for case C.

Case C-1, in conjunction with fig. 1a above, the target device is a PGW.

After the terminal accesses the 4G access network, that is, after the terminal accesses the MME of the core network through the E-UTRAN, step 301 to step 302 in fig. 3 are executed, the MME acquires the second APN-AMBR parameter corresponding to the LTE, and after the terminal is switched from the 4G access network to the 5G access network, the terminal accesses the MME + of the core network through the 5G-RAN, step 303 to step 304 in fig. 3 may be executed, and the MME + acquires the first APN-AMBR parameter corresponding to the NR. The terminal accesses the 4G access network first, and then switches from the 4G access network to the 5G access network, and the terminal may detect that the 4G access network is switched to the 5G access network, as shown in fig. 7, which is a schematic flow chart of another parameter determination method provided by the present application. The method comprises the following steps:

in step 701, the terminal detects that the second access network is switched to the first access network.

Here, the first access network is an NR access network, and the second access network is an LTE access network.

In a possible implementation manner, the terminal determines that the access network before handover is an LTE access network, and the access network after handover is an NR access network, which indicates that the terminal detects that the access network is handed over from the second access network to the first access network.

In step 702, the terminal notifies the PGW through the MME + to modify the APN-AMBR parameter from the second APN-AMBR parameter to the first APN-AMBR parameter.

In a possible implementation, the notification in this step may carry the first APN-AMBR parameter and/or the type of the first access network.

In step 703, the PGW modifies the current APN-AMBR parameter from the second APN-AMBR parameter to the first APN-AMBR parameter.

As can be seen from steps 701 to 703, after the terminal senses that the type of the access network changes, the terminal actively initiates a procedure of modifying the APN-AMBR parameter, so as to implement that the APN-AMBR parameter used by the terminal matches with the current network capability of the access.

Case C-2, in conjunction with fig. 1b above, the target device is SMF.

After the terminal accesses the 4G access network, that is, after the terminal accesses the MME of the core network through the E-UTRAN, step 301 to step 302 in fig. 3 are executed, the MME acquires the second APN-AMBR parameter corresponding to the LTE, and after the terminal is switched from the 4G access network to the 5G access network, and after the terminal accesses the AMF in the core network through the 5G-RAN, the AMF notifies the SMF that the terminal has accessed the core network, step 401 to step 403 in fig. 4 may be executed, and the SMF acquires the first APN-AMBR parameter corresponding to the NR from the HSS +/UDM. The terminal accesses the 4G access network first, and then switches from the 4G access network to the 5G access network, and the terminal may detect that the 4G access network is switched to the 5G access network, as shown in fig. 8, which is a schematic flow chart of another parameter determination method provided by the present application. The method comprises the following steps:

in step 801, a terminal detects that access is switched from a second access network to a first access network.

This step is the same as the implementation of step 701 described above, and is not described here again.

And step 802, the terminal informs the SMF through the AMF to modify the current APN-AMBR parameter from the second APN-AMBR parameter to the first APN-AMBR parameter.

In step 803, the SMF modifies the current APN-AMBR parameter from the second APN-AMBR parameter to the first APN-AMBR parameter.

Based on the method shown in fig. 8, the data management entity issues a specific subscription APN-AMBR parameter according to the type of the access network of the terminal, and actively initiates a process of modifying the APN-AMBR parameter after the terminal senses that the type of the access network changes, so as to match the APN-AMBR parameter used by the terminal with the currently accessed network. Moreover, after switching from the 4G network to the 5G network, the advantages of the 5G network can be fully utilized by modifying the APN-AMBR parameter.

For scenario two, three scenarios are also possible.

In case D, the steps 211 to 212 are performed by the MME, and the target device is the PGW.

Case D-1, with reference to fig. 1a, the access network device when the terminal accesses the second access network is MME +, and the access network device when the terminal accesses the first access network is MME.

For a detailed parameter determination process, reference may be made to the description of fig. 3, and specifically, the MME in fig. 3 may be replaced by an MME +, and the MME + is replaced by an MME, which is not described herein again.

Case D-2, in conjunction with fig. 1b above, steps 211 through 212 are performed by the AMF, and the target device is the SMF.

In this case, the access network device when the terminal accesses the second access network is the AMF, and the access network device when the terminal accesses the first access network is the MME.

For a detailed parameter determination process, reference may be made to the description in fig. 4, and specifically, the MME in fig. 4 may be replaced by an AMF, and the AMF may be replaced by an MME, which is not described herein again.

In case E-1, referring to fig. 1a, the access network device when the terminal accesses the second access network is MME +, and the access network device when the terminal accesses the first access network is MME.

For a detailed parameter determination process, reference may be made to the description of fig. 5, and specifically, the MME in fig. 5 may be replaced by an MME +, and the MME + is replaced by an MME, which is not described herein again.

For a detailed parameter determination process, reference may be made to the description in fig. 6, and specifically, the MME in fig. 6 may be replaced by an AMF, and the AMF may be replaced by an MME, which is not described herein again.

In case F, the above steps 211 and 212 are performed by the terminal, and the target device is a PGW.

In case F-1, with reference to fig. 1a, the access network device when the terminal accesses the second access network is MME +, and the access network device when the terminal accesses the first access network is MME.

For a detailed parameter determination process, reference may be made to the description of fig. 7, and specifically, the MME in fig. 7 may be replaced by an MME +, and the MME + is replaced by an MME, which is not described herein again.
