Detailed ways

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in various forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concepts of the example embodiments. To those skilled in the art. The described features, structures or characteristics may be combined in any suitable manner in one or more embodiments.

Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings represent the same or similar parts, and thus their repeated description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and/or processor devices and/or microcontroller devices.

In the current 3GPP (3rd Generation Partnership Project) specification, when BSF is deployed in a distributed manner, there will be multiple BSFs. For IP type PDU (Protocol Data Unit) sessions, AF (Application Function) searches for the corresponding BSF based on the UE IP address range. Each BSF is responsible for a different IP range (IP range). When the BSF registers with the NRF (NF Register Function, network registration function), it will bring the responsible UE IP address range, but for Ethernet type PDU sessions, that is, the UE address is a MAC address type, it cannot find the BSF by dividing the range like the IP address. If the AF wants to find the BSF based on the MAC address, it needs to go to each one every time. BSF sends a lookup request, which results in very low efficiency, and a lot of signaling transmission is added to the network, resulting in low session binding efficiency.

Among them, the MAC address is a hardware address, which is used to define the location of the network device. The MAC address has a total of 48 bits (6 bytes) and is expressed in hexadecimal. The last 24 bits are allocated by various organizations such as IEEE, and the first 24 bits are designated by the manufacturer who actually produces the network equipment.

Based on the above shortcomings, the present disclosure provides a session binding method, which is applied to the central data terminal. Referring to FIG. 1 , the central data terminal performs step S101 to summarize information on multiple binding support functions into session binding data.

In step S110, the information of multiple binding support functions is summarized into session binding data;

The binding support function information includes a user terminal address, a binding support function address, and policy control function information. The session binding data is used to bind the target terminal address based on the target terminal address sent by the binding information requesting end. The policy control function information corresponding to the terminal address is fed back to the binding information requesting end.

In this example real-time mode, the central data terminal can respond to the registration request of the above-mentioned binding support function and summarize the above-mentioned binding support function information into session binding data, wherein the user terminal address in the above-mentioned binding support function information is and policy control function information is registered and provided by the policy control function.

Specifically, the user can send a session establishment request to the above-mentioned policy control function, and then the policy control function will register the user address and policy control function information to the above-mentioned binding support function, so that the above-mentioned central data end can aggregate multiple bindings Information about supported features.

In this example implementation, the above-mentioned user terminal address is the user UE MAC address, and may also be other non-IP type addresses, which is not specifically limited in this example implementation.

In this exemplary embodiment, referring to FIG. 2 , the above-mentioned central data terminal may further include steps S210 to S230. in particular:

In step S210, the target terminal address sent by the binding information requesting end is received.

In an example implementation of the present disclosure, the above-mentioned target terminal address may be the target UE MAC address, which may be sent by the binding information requesting end. The above-mentioned binding information requesting end may be an AF (Application Function, application function) connected to the NEF ( Network Exposure Function), or it can be a separate AF, which is not specifically limited in this example implementation.

In step S220, it is determined in the session binding data according to the target terminal address and the user terminal address that the target terminal address corresponds to the policy control function information.

In an example implementation of the present disclosure, after receiving the above-mentioned target terminal address, the central data terminal compares the above-mentioned target address with the above-mentioned user terminal address, and searches for whether any of the multiple user terminal addresses is consistent with the target terminal address. If there is a user terminal address, the policy control function information corresponding to the user terminal address is determined as the policy control function information corresponding to the target terminal address.

In step S230, the policy control function information is fed back to the binding information requesting end.

In an example implementation of the present disclosure, after the above-mentioned central data terminal obtains the corresponding policy control function information according to the above-mentioned target terminal address, the policy control function information can be fed back to the above-mentioned binding information requesting terminal.

If there is no user terminal address that is the same as the target terminal address in the central data terminal, the central data terminal feeds back binding failure information to the binding information requesting terminal. In this example implementation, the binding failure information can be text information such as "no matching item", "binding failure", etc., or it can also be numerical information. For example, the central data terminal can send "0" to the above-mentioned data requesting terminal. Indicates binding failure. The content of the binding failure information can be customized according to user needs and is not specifically limited in this example implementation.

In this example implementation, the policy control function information may include address information of the policy control function bound to the user.

In an example implementation of the present disclosure, with reference to Figure 3, step S310 can be performed first. The UE can send a UE PDU session establishment request to the above-mentioned policy control function, and the policy control function receives the above-mentioned UE PDU session establishment request. Afterwards, the policy control function executes step S302 to register the user address and policy control function information to the above-mentioned binding support function. The binding support function executes steps S303 and S304, feeds back registration success information to the policy control function, and then sends the above-mentioned binding support function information to the above-mentioned central data terminal, wherein the above-mentioned binding support function information may include the user terminal address , binding support function address and policy control function information.

Further, the present disclosure also provides a session binding method, which is applied to the binding information requesting end. Referring to Figure 4, the session binding step may include the following steps:

Step S410, receive the center data terminal address;

Step S420: Send a target terminal address to the central data terminal so that the central data terminal can feed back policy control function information corresponding to the target terminal address according to the target terminal address.

In this example implementation, the above-mentioned binding information requesting end may be composed of an AF (Application Function, application function) connected to an NEF (Network Exposure Function, network opening function), or it may be a separate AF. No specific limitation is made in this exemplary embodiment.

Each of the above steps is explained in detail below.

In step S410, the center data terminal address is received.

In this example implementation, the above-mentioned binding information requester can carry information including the target terminal address to the network registration function to search for the central data terminal. After the above-mentioned network registration function receives the search request, the above-mentioned central data terminal address is sent to the above-mentioned central data terminal. The binding information requesting end is bound to receive the above-mentioned center data end address.

In step S420, a target terminal address is sent to the central data terminal so that the central data terminal can feed back policy control function information corresponding to the target terminal address according to the target terminal address.

In an example implementation of the present disclosure, after obtaining the above-mentioned central data terminal address, the binding information requesting terminal sends the target terminal address to the above-mentioned central data terminal based on the above-mentioned central data terminal address, so that the central data terminal sends the above-mentioned central data terminal The policy control function information corresponding to the target terminal address is fed back to the binding information requesting end.

After receiving the above-mentioned target terminal address, the central data terminal compares the above-mentioned target address with the above-mentioned user terminal address, and searches for whether there is a user terminal address consistent with the target terminal address among multiple user terminal addresses. If so, it will be given to The policy control function information corresponding to the user terminal address is determined as the policy control function information corresponding to the target terminal address.

Furthermore, the present disclosure also discloses a session binding method for binding the support function terminal, which may include step S510 and step S520 as shown in FIG. 5 .

In step S510, a registration request for the policy control function is received, and the user terminal address and policy control function information are obtained.

In this example implementation, the binding support function receives the registration request of the policy control function, and obtains the user terminal address and policy control function information from the policy control function, where the user terminal address is the policy when the UE registers with the policy control function. The policy control function information obtained by the control function may be the policy control function address.

In step S520, the binding support function address user terminal address and policy control function information are transmitted to the central data terminal as the binding support function information, so that the central data terminal Information about supported features is summarized as session binding data.

In an example implementation of the present disclosure, the binding support function sends its own address, that is, the binding support function address and the above-mentioned user terminal address and policy control function information as the binding support function information to the central data terminal, so that The central data end can summarize information about binding support functions into session binding data.

The process of the central data terminal summarizing the information about binding support functions into session binding data has been described in detail above, so it will not be described again here.

Furthermore, the present disclosure also discloses a new session binding method, which is applied to the network registration function. In the service registration, the session establishment request of the binding information requesting end is received, and the central data end address is sent to the binding information. The requesting end is so that the binding information requesting end obtains the policy control function information corresponding to the target terminal address from the central data end according to the target terminal address.

Among them, the specific working process of the above-mentioned network registration function has been introduced in detail above, so it will not be described again here.

Specifically, referring to Figure 6, the network registration function may first perform step S601 to receive a search request from the binding information requesting end carrying information including the target terminal address, and then perform step S602 to send the binding information requesting end to the binding information requesting end. Feed back the central data end address, so that the above-mentioned binding information requesting end obtains the policy control function information corresponding to the target terminal address at the central data end according to the target terminal address. Specifically, the above-mentioned binding information requesting end may perform step S603 to The central data terminal sends the target terminal address, and then the central data terminal can perform step S604 to feed back the policy control function information to the above-mentioned binding information requesting terminal.

The present disclosure also provides a session binding function, which may include a central data terminal and a binding support function terminal. The binding support function terminal is configured to receive a registration request for the policy control function, obtain the user terminal address and policy control function information, and The binding support function address user terminal address and policy control function information are transmitted to the central data terminal as the binding support function information; the central data terminal is configured to transmit multiple binding support function information Summarized into session binding data; the binding support function information includes user terminal address, binding support function address and policy control function information; the session binding data is configured to be based on the target terminal sent by the binding information requesting end address, and feeds back the policy control function information corresponding to the target terminal address to the binding information requesting end.

In this example implementation, the functions and execution steps of the central data terminal and the binding support function can be referred to the above description of the binding session function, and will not be described again here.

To sum up, in this exemplary embodiment, the present disclosure uses a central data end to summarize the information of binding support functions into session binding data. When performing session binding, it only needs to be based on the sending target of the binding information requesting end. By using the terminal address, the search and feedback of the policy control function information can be completed at the central data end, and the session binding can be completed without sending a search request to the binding support function, which reduces the amount of data output and improves the efficiency of session binding.
