[0050] First, the English terms used in the embodiments of the present invention are described: Session Management Function (SMF) module, User Plane Function (UPF) module, Heartbeat Request message, Heartbeat Response message, Load Control Information, Overload Control Information, and Central Processing Unit (CPU).

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0052] In this application, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0053] An embodiment of the present invention discloses a data processing method and system. When a UPF module and an SMF module are in an associated state, the UPF module uses target type messages other than session-level messages to report at least one of Load Control Information and OverLoad Control Information to the SMF module, thereby improving the flexibility of the UPF module in reporting at least one of Load Control Information and OverLoad Control Information to the SMF module.

[0054] like Figure 1 FIG. 1 is a flow chart of a data processing method disclosed in an embodiment of the present invention. The data processing method is applied to the UPF module and mainly includes the following steps:

[0055] Step S101: Control the UPF module and the SMF module to be in an associated state.

[0056] The UPF module is used for user plane message transmission, and the SMF module is used for control plane user session management.

[0057] The process of establishing an association between the UPF module and the SMF module is as follows:

[0058] First, the UPF module sends an association request message to the SMF module. Then, the SMF module receives the association request message and feeds back an association response message to the UPF module. Finally, the UPF module receives the association response message and establishes an association with the SMF module based on the PFCP protocol.

[0059] After the UPF module and the SMF module are associated, they send Heartbeat Request messages to each other to detect whether the other end is alive, and the receiver sends a Heartbeat Response message to indicate that it is in normal operation.

[0060] Step S102: Interact target type messages with the SMF module in the associated state, where the target type messages are messages other than the session level messages interacting with the SMF module; wherein the target type messages carry at least one of Load Control Information and OverLoad Control Information, and Load Control Information and OverLoad Control Information are used to indicate the load status of the UPF module.

[0061] When the UPF module and the SMF module are in an associated state, one way to exchange target type messages is that the UPF module encapsulates the target type messages carrying Load Control Information and OverLoad Control Information, and periodically sends the target type messages to the SMF module.

[0062] For example, after encapsulating a target type message carrying Load Control Information and OverLoad Control Information, the target type message is sent to the SMF module multiple times at regular intervals to prevent the loss of target type messages due to network anomalies and / or module anomalies. For another example, a target type message carrying Load Control Information and OverLoad Control Information is periodically encapsulated, and each time a target type message is encapsulated, a target type message is sent to the SMF module. This method can update the Load Control Information and OverLoad Control Information in the target type message in real time according to the load status of the UPF module to ensure that the Load Control Information and OverLoad Control Information obtained by the SMF module are consistent with the load status of the UPF module.

[0063] The duration period for periodically sending target type messages to the SMF module is set by technical personnel according to actual conditions. The present invention does not make any specific restrictions on the specific duration period for periodically sending target type messages to the SMF module.

[0064] Currently, the UPF module can use session-level messages to send Load Control Information and OverLoad Control Information. Session-level messages include PFCP session creation messages, PFCP session modification messages, and PFCP session deletion request messages.

[0065] When the UPF module and the SMF module need to conduct session-level services, the UPF module receives the PFCP session creation message, PFCP session modification message, and PFCP session deletion request message sent by the SMF module. As a result, the UPF module can only feedback Load Control Information and OverLoad Control Information when conducting session-level services. This embodiment adjusts the ability to feedback Load Control Information and OverLoad Control Information so that other types of messages besides session-level messages can also feedback Load Control Information and OverLoad Control Information.

[0066] For example, after the UPF module and the SMF module are associated, they send Heartbeat Request messages to each other to detect whether the other end is alive. The receiver sends a Heartbeat Response message to indicate that it is in normal operation. Then the Heartbeat Request message or the Heartbeat Response message can be used as a target type message to feedback Load Control Information and OverLoad Control Information through the Heartbeat Request message or the Heartbeat Response message, thereby increasing the feedback path of Load Control Information and OverLoadControl Information.

[0067] In an embodiment of the present invention, when the UPF module and the SMF module are in an associated state, the UPF module uses target type messages other than session-level messages to periodically report at least one of Load Control Information and OverLoad Control Information to the SMF module, thereby improving the flexibility of the UPF module in reporting at least one of Load Control Information and OverLoad Control Information to the SMF module.

[0068] like Figure 2 FIG. 1 is a flow chart of another data processing method disclosed in an embodiment of the present invention. The data processing method is applied to the UPF module and mainly includes the following steps:

[0069] Step S201: The UPF module controls the UPF module and the SMF module to be in an associated state.

[0070] The execution process and execution principle of step S201 are consistent with the execution process and execution principle of the above-mentioned step S101, which can be used as a reference and will not be repeated here.

[0071] Step S202: The UPF module obtains the load status of the UPF module.

[0072] The load status of the UPF module indicates the current usage status of the UPF module. The load status of the UPF module includes the CPU utilization change rate and the context occupancy change rate.

[0073] Step S203: When the load status of the UPF module meets the preset reporting conditions, the UPF module encapsulates Load Control Information and OverLoad Control Information in a target type message.

[0074] The load status of the UPF module includes but is not limited to the CPU utilization change value, the context occupancy change value, etc. When the CPU utilization change rate is greater than the preset CPU utilization change rate and the context occupancy change rate is greater than the preset occupancy change rate, the UPF module encapsulates the Load Control Information and OverLoad Control Information in the target type message.

[0075] The preset CPU utilization change rate is set by technicians according to actual conditions, and the present invention does not make any specific limitation.

[0076] The preset occupancy change rate is set by technical personnel according to actual conditions and is not specifically limited in the present invention.

[0077] To facilitate understanding of the process of encapsulating Load Control Information and OverLoad Control Information in a target type message when the load status of the UPF module meets the preset reporting conditions, an example is provided here to illustrate:

[0078] For example, the UPF module configures the reporting conditions, configures the preset CPU utilization change rate to 3%, and the preset occupancy change rate to 5%. When the CPU utilization change value in the load change information of the UPF module is 5%, and the context occupancy rate is 6%, then the CPU utilization change value 5% is greater than the CPU utilization change rate 3%, and the context occupancy rate 6% is greater than the preset occupancy change rate 5%. It is determined that the load change information of the UPF module meets the reporting conditions, and the UPF module encapsulates the Load Control Information and OverLoadControl Information in the target type message.

[0079] Step S204: The UPF module sends a target type message to the SMF module.

[0080] In step S204, the UPF module may send target type messages to the SMF module multiple times to prevent the target type messages from being lost due to network anomalies and / or module anomalies.

[0081] In an embodiment of the present invention, when the UPF module and the SMF module are in an associated state, the UPF module uses target type messages other than session level messages to report at least one of Load Control Information and OverLoad Control Information to the SMF module, thereby realizing carrying at least one of load control information and overload control information in target type messages other than session level messages for reporting. In this way, messages other than session level messages can be adjusted, and at least one of load control information and overload control information is reported when sending messages other than session level messages, thereby improving the flexibility of the user plane function module in reporting at least one of load information and overload information to the session management function module.

[0082] Optionally, in the associated state, the UPF module receives the Heartbeat Request message sent by the SMF module, the UPF module responds to the Heartbeat Request message, and the UPF module sends a Heartbeat Response message carrying Load Control Information and OverLoad Control Information to the SMF module.

[0083] As described above for the association establishment process, after the UPF module and the SMF module are associated, they send Heartbeat Request messages to each other to detect whether the other end is alive. The receiver sends a Heartbeat Response message to indicate that it is in normal operation. Therefore, the above-mentioned target type message can be a Heartbeat Request message or a Heartbeat Response message. The target type message has a Load Control Information field and / or an Overload Control Information field. The Load Control Information field is used to write LoadControl Information, and the Overload Control Information field is used to write OverLoad ControlInformation. Target type messages include but are not limited to HeartbeatRequest messages, Heartbeat Response messages, etc.

[0084] For example, after receiving a Heartbeat Request message, the UPF module encapsulates Load Control Information and OverLoad Control Information in a Heartbeat Response message. The Heartbeat Response message is a target-type message. Furthermore, the Heartbeat Response message indicates that the UPF module is operating normally, allowing the Heartbeat Response message to provide both operational and load information.

[0085] like Figure 3 FIG. 1 is a flow chart of another data processing method according to an embodiment of the present invention. The data processing method is applied to the SMF module and mainly includes the following steps:

[0086] Step S301: The SMF module controls the SMF module and the UPF module to be in an associated state.

[0087] The process of establishing an association between the SMF module and the UPF module is as follows:

[0088] First, the SMF module sends an association request message to the UPF module. Then, the UPF module receives the association request message and feeds back an association response message to the SMF module. Finally, the SMF module receives the association response message and establishes an association with the UMF module based on the PFCP protocol.

[0089] After the SMF module and the UPF module are associated, they send Heartbeat Request messages to each other to detect whether the other end is alive, and the receiver sends a Heartbeat Response message to indicate that it is in normal operation.

[0090] Step S302: The SMF module obtains a target type message from the UPF module in an associated state. The target type message is a message other than a session-level message interacting with the SMF module.

[0091] The target type message carries at least one of Load Control Information and OverLoad Control Information, and Load Control Information and OverLoad Control Information are used to indicate the load status of the UPF module.

[0092] The target type message obtained by the SMF module from the UPF module in the associated state can be:

[0093] The SMF module receives the target type message sent by the UPF module. The target type message is sent when the load status of the UPF module meets the preset reporting conditions or is sent periodically by the UPF module. Among them, if the load status of the UPF module meets the preset reporting conditions, please refer to the above step S203. If the UPF module sends it periodically, please refer to the above step S102. No further details will be given here.

[0094] or,

[0095] In the associated state, the SMF module sends a Heartbeat Request message to the UPF module and receives a Heartbeat Response message carrying Load Control Information and OverLoad Control Information from the UPF module. The Heartbeat Response message is sent by the UPF module in response to the Heartbeat Request message.

[0096] Step S303: The SMF module extracts at least one of Load Control Information and OverLoad Control Information from the target type message. The Load Control Information and OverLoad Control Information are used to indicate the load status of the UPF module.

[0097] The target type message may be a heartbeat request message or a heartbeat response message. The target type message includes a LoadControl Information field and / or an Overload Control Information field. The Load ControlInformation field is used to write Load Control Information, and the Overload Control Information field is used to write OverLoad Control Information.

[0098] The corresponding SMF module extracts at least one of Load Control Information and OverLoad Control Information from the target type message, which may be extracted from the Load Control Information field and / or the Overload Control Information field.

[0099] Step S304: The SMF module adjusts the service of the user plane function module based on at least one of the Load Control Information and the OverLoad Control Information.

[0100] According to the 3GPP protocol, when a user accesses the core network to create a session, the SMF module needs to select the UPF module based on multiple parameters. If the UPF1 module and the UPF2 module are available, the UPF1 module has a higher load and the UPF2 module has a lower load. When a new user creates a session, the SMF module can select the UPF2 module with a lower load, which is to perform a load adjustment operation on the UPF module. Through this process, the effect of load sharing between the two UPF modules is achieved.

[0101] In an embodiment of the present invention, when the UPF module and the SMF module are in an associated state, the SMF module obtains a target type message from the UPF module in the associated state, and the SMF module extracts at least one of Load Control Information and OverLoad Control Information from the target type message. Based on at least one of Load Control Information and OverLoad Control Information, the SMF module adjusts the service of the user plane functional module to achieve the purpose of load sharing for the UPF module.

[0102] For simplicity of description, the aforementioned method embodiments are described as a series of actions. However, those skilled in the art should be aware that the present invention is not limited by the order of the actions described, as certain steps can be performed in other orders or simultaneously according to the present invention. Furthermore, those skilled in the art should also be aware that the embodiments described in this specification are preferred embodiments, and the actions and modules involved are not necessarily required for the present invention.

[0103] Based on the above embodiment Figure 1 A data processing method is disclosed, and an embodiment of the present invention also discloses a data processing system. Figure 4 As shown, the data processing system mainly includes a first control unit 401 and an interaction unit 402 .

[0105] Interaction unit 402 is configured to exchange target-type messages with the SMF module in the associated state. Target-type messages are messages other than session-level messages exchanged with the SMF module. Target-type messages carry at least one of Load Control Information and OverLoad Control Information, which are used to indicate the load status of the UPF module.

[0106] Furthermore, it also includes an acquisition module.

[0107] The acquisition module is used to obtain the load status of the UPF module.

[0108] The interaction unit 402 includes a first encapsulation module and a first sending module.

[0113] The second encapsulation module is used to encapsulate the target type message carrying Load Control Information and OverLoad Control Information.

[0115] For example, after the second encapsulation module encapsulates a target type message carrying Load Control Information and OverLoad Control Information, the second sending module sends the target type message to the SMF module multiple times at regular intervals to prevent the problem of target type message loss due to network anomalies and / or module anomalies. For another example, the second encapsulation module periodically encapsulates a target type message carrying Load Control Information and OverLoad Control Information. Every time a target type message is encapsulated, the second sending module sends the target type message to the SMF module. This method can update the LoadControl Information and OverLoad Control Information in the target type message in real time according to the load status of the UPF module to ensure that the LoadControl Information and OverLoad Control Information obtained by the SMF module are consistent with the load status of the UPF module.

[0116] Furthermore, it also includes a receiving unit.

[0117] The receiving unit is used to receive the request message sent by the SMF module in the associated state.

[0118] The interaction unit 402 is specifically configured to respond to the request message and send a Heartbeat Response message carrying Load Control Information and OverLoad Control Information to the SMF module.

[0119] In an embodiment of the present invention, when the UPF module and the SMF module are in an associated state, the UPF module uses target type messages other than session level messages to report at least one of Load Control Information and OverLoad Control Information to the SMF module, thereby realizing carrying at least one of load control information and overload control information in target type messages other than session level messages for reporting. In this way, messages other than session level messages can be adjusted, and at least one of load control information and overload control information is reported when sending messages other than session level messages, thereby improving the flexibility of the user plane function module in reporting at least one of load information and overload information to the session management function module.

[0121] The second control unit 501 is used to control the SMF module and the UPF module to be in an associated state.

[0122] The acquisition unit 502 is used to obtain target type messages from the UPF module in the associated state, where the target type messages are messages other than session level messages interacting with the SMF module.

[0124] The adjusting unit 504 is configured to adjust services of the user plane functional module based on at least one of Load Control Information and OverLoad Control Information.

[0125] Furthermore, the acquiring unit 502 includes a first receiving module.

[0126] The first receiving module is used to receive a target type message sent by the UPF module. The target type message is sent when the load status of the UPF module meets the preset reporting conditions or is sent periodically by the UPF module.
