Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a data forwarding processing method, apparatus, device and medium. Background Technology

[0002] The Service Communication Proxy (SCP) network element supports data forwarding between network elements. That is, the SCP network element acts as a message proxy network element, and each time it receives a service request packet sent by the service request network element, it forwards the service request packet to the service response network element.

[0003] In related technologies, after the SCP network element obtains the encoded service request packet, it decodes the entire service request packet to obtain the decoded string message. Based on the decoded string message, it obtains the address of the next-hop network element, modifies the string message according to the address of the next-hop network element, re-encodes the modified string message, and forwards the re-encoded service request data packet to the next-hop network element.

[0004] However, the encoding and decoding operations performed by the aforementioned SCP network elements during packet forwarding consume a significant amount of SCP's computing power, thus affecting SCP's performance. Summary of the Invention

[0008] This disclosure also provides a data forwarding processing apparatus applied to a Service Proxy (SCP) network element, comprising: an acquisition module for acquiring an encoded first service request packet sent by a service request network element, wherein the header field of the first service request packet includes a first header field and a second header field, the first header field corresponding to a first network element address of a target service response network element, and the second header field corresponding to a second network element address of a next-hop service response network element; a determination module for decoding the first header field to obtain the first network element address, and determining the second network element address of the next-hop service response network element based on the first network element address; a query module for querying a preset mapping table to determine whether a second network element address encoding index value corresponding to the second network element address is included; and an update processing module for updating the initial field value of the second header field to the second network element address encoding index value when the second network element address encoding index value is included, and forwarding the updated first service request packet to the next-hop service response network element corresponding to the second network element address.

[0010] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0011] The data forwarding processing scheme provided in this disclosure obtains an encoded first service request packet sent by a service requesting network element. The header field of the first service request packet includes a first header field and a second header field.

[0020] In this disclosure, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0021] In this disclosure, the term "multiple" refers to two or more, and other quantifiers are similar.

[0022] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0023] The data forwarding processing method and apparatus of this disclosure are used to reduce the computing power consumption of SCP network elements and improve the performance of SCP network elements.

[0024] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0025] The technical solutions provided in this disclosure can be applied to a variety of systems. For example, applicable systems may include Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, Long Term Evolution Advanced (LTE-A) systems, Universal Mobile Telecommunications System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) systems, 5G New Radio (NR) systems and their evolved communication systems, and 6G (sixth generation mobile communication technology) systems. These systems may include terminal equipment and network equipment. The systems may also include a core network component, such as the Evolved Packet Core (EPC) or the 5G Core Network (5GC).

[0026] In related technologies, the SCP network element acts as a service proxy network element, forwarding relevant data packets between network elements. Taking the use of SCP for data forwarding between Unified Data Management (UDM) network elements and Session Management (SMF) network elements as an example, such as... Figure 1 As shown, the SCP network element acts as a service proxy, forwarding data packets between relevant UDM network elements and SMF network elements. Figure 1 The UDM network elements include UDM-1, UDM-2, UDM-3, and UDM-4, ​​and the SMF network elements include SMF-1, SMF-2, SMF-3, and SMF-4. When the relevant network elements communicate with each other, the service requesting network element will discover the network element address of the service responding network element through the Registration and Discovery Function (NF Repository Function, NRF).

[0027] In actual communication, if the data packets forwarded by the SCP network element are sent based on the Hypertext Transfer Protocol (HTTP), then refer to... Figure 2 The service request network element A (which can also be seen as a consumer network element in an HTTP-based service scenario) communicates with the NRF network element to obtain the network element address b of the target service response network element B (which can also be seen as a producer network element in an HTTP-based service scenario). A fills b into the HTTP header field of the first service request packet S1, for example, the 3gpp-sbi-target-apiroot field. Then, it fills the network element address c of the SCP network element into the HTTP header field, for example, the authority field. A encodes S1 with the relevant network element addresses to obtain the encoded S2, and sends S2 to the SCP network element. The SCP network element decodes S2 to obtain S3, reads the content of the 3gpp-sbi-target-apiroot field, fills the network element address b of B into the authority field of the HTTP header, encodes the modified S3 to obtain S4, and sends S4 to B. After B generates service response data, it passes the service response data through the SCP to A.

[0028] As can be seen from the above description, the SCP network element, as a forwarding proxy network element for HTTP messages, needs to decode the HTTP header, replace the field values ​​in the relevant fields, and then re-encode each packet. The processing flow is complex and consumes a lot of resources, which can easily affect the performance of SCP.

[0029] To address the aforementioned technical issues, this disclosure proposes a data forwarding processing method, which is applied to SCP network elements.

[0030] Figure 3 This is a flowchart illustrating a data forwarding processing method according to an embodiment of the present disclosure, as shown below. Figure 3 As shown, the method includes:

[0031] Step 301: Obtain the encoded first service request packet sent by the service request network element. The header field of the first service request packet includes a first header field and a second header field. The first header field corresponds to the first network element address of the target service response network element, and the second header field corresponds to the second network element address of the next-hop service response network element.

[0032] In this context, the service request network element can be either the consumer network element that triggers the service request or a transitional network element that participates in the intermediate message forwarding during the service request execution process. For example, for a service request packet sent by consumer network element W, the routing link is W network element - E network element - R network element - T network element. The network elements forward relevant messages through SCP network elements as service proxy network elements. In this embodiment, the service request network element can be W network element, E network element, R network element, etc.

[0033] In this embodiment, the target service response network element can be understood as the final response network element in the service request scenario. For example, the target service response network element is the aforementioned network element T.

[0034] In one embodiment of this disclosure, an encoded first service request packet sent by a service request network element is obtained. The header field of the first service request packet includes a first header field and a second header field. The second header field can be one or more, and can be set according to the needs of the scenario. For example, in a scenario based on HTTP communication, the first header field can include the 3gpp-sbi-target-apiroot field, and the second header field can include the authority field.

[0035] The first header field corresponds to the first network element address of the target service response network element. This can be understood as storing the first network element address or an index value corresponding to it. Therefore, the first network element address of the target service response network element can be uniquely determined based on the first header field. The second header field corresponds to the second network element address of the next-hop service response network element. This can also be understood as storing the second network element address or an index value corresponding to it. Therefore, the network element address of the next-hop service response network element can be uniquely determined based on the second header field. The network element address of the next-hop service response network element can include an SCP network element, the target service response network element, or other service network elements in the core network. Other service network elements in the core network can include SCP network elements in other core networks, or network elements other than other SCP network elements in other core networks. The next-hop service response network element is the service request data packet. In the current scenario, the next network element to be sent, continuing with the above embodiment as an example, when the service request network element is network element W, then network element E is the next-hop service response network element.

[0036] Step 302: Decode the first header field to obtain the first network element address, and determine the second network element address of the next-hop service response network element based on the first network element address.

[0037] In one embodiment of this disclosure, to reduce the computational power consumption of the SCP network element, only the first header field can be decoded to obtain the first network element address, and the second network element address of the next-hop service response network element can be determined based on the first network element address. In some possible embodiments, an internal routing table can be queried to obtain the second network element address of the next-hop service response network element corresponding to the first network element address. Here, the next-hop service response network element is relative to the service request network element.

[0038] Step 303: Query the preset mapping table to determine whether it contains the second network element address encoding index value corresponding to the second network element address.

[0039] It should be noted that in business request scenarios, after forwarding relevant business request data packets, a preset mapping table is set in advance. This preset mapping table stores the mapping relationship between network element addresses and network element address encoding index values. Thus, based on the preset mapping table, the network element address encoding index value corresponding to the network element address can be retrieved without re-encoding the network element address. The network element address encoding index value is the encoded value.

[0040] It is easy to understand that after the initial forwarding of the service request data packet between two network elements, the correspondence between the network element address and the network element address encoding index value can be stored in the preset mapping table. The correspondence in the preset mapping table can be reused when the service request data packet is sent to the corresponding network element next time.

[0041] Therefore, in one embodiment of this disclosure, before decoding the first header field to obtain the first network element address, it is also necessary to determine whether the SCP network element is a service request packet between the network element that first forwards the service request and the target service response network element. For example, historical service forwarding path information can be stored in advance, which stores the network elements traversed by each service request. Based on this historical service forwarding path information, it can be determined whether the SCP network element is a service request packet between the network element that first forwards the service request and the target service response network element.

[0042] For example, in some possible embodiments, after resolving the first network element address, after querying the internal routing table to determine the second network element address, the preset mapping table can be directly queried to determine whether it contains the second network element address encoding index value corresponding to the second network element address. If the second network element address encoding index value is found, it is determined that the SCP network element is not a service request packet between the first forwarding service request network element and the target service response network element; otherwise, it is determined that the SCP network element is a service request packet between the first forwarding service request network element and the target service response network element.

[0043] Step 304: When the second network element address encoding index value is included, update the initial field value of the second header field to the second network element address encoding index value, and forward the updated first service request packet to the next-hop service response network element corresponding to the second network element address.

[0044] In one embodiment of this disclosure, when the second network element address encoding index value is included, the initial field value of the second header field is updated to the second network element address encoding index value, and the updated first service request packet is forwarded to the next-hop service response network element corresponding to the second network element address. Here, the first network element address in the updated first service request is now an encoded value, for example, it can be a re-encoded value or a historical encoding index value after querying the first network element address. Therefore, the SCP network element only needs to decode the first header field and simply replace the encoded field value in the second header field, without needing to perform overall decoding and encoding of the first service request packet, greatly reducing the computing power consumption of the SCP network element, improving its performance, and increasing the speed of SCP network element packet forwarding.

[0045] In some possible embodiments, in order to further improve the performance of SCP packets, the field positions corresponding to the second header fields can be pre-stored. For example, when multiple second header fields are included, the field positions corresponding to each second header field can be stored. The field position may include the number of bytes, etc. Thus, when the second network element address encoding index value is included, the pre-stored field positions corresponding to the second header fields are queried, and the initial field values ​​corresponding to the second header fields are updated to the second network element address encoding index values ​​according to the field positions.

[0046] In another embodiment of this disclosure, if the SCP network element is determined to be a service request packet between the first forwarding service request network element and the target service response network element, then the first service request packet is decoded to obtain the decoded service request string. That is, the first service request packet is decoded as a whole during the first forwarding, the first network element address corresponding to the first header field in the service request string is determined, the second network element address of the next-hop service response network element is determined based on the first network element address, the initial field value corresponding to the second header field in the service request string is updated to the second network element address, and then the updated service request string is encoded to obtain the encoded second service request packet.

[0047] The encoding algorithm used to encode the updated business request string can be any encoding algorithm. In the scenario of business requests based on HTTP / 2, the encoding algorithm can be the HTTP / 2 header compression algorithm (HPACK). The HPACK algorithm introduces static and dynamic tables to map strings to binary encoded values, which greatly reduces the transmission volume. In this embodiment, if the first header field 3gpp-sbi-target-apiroot: in the decoded business request string is http: / / [240a:0000:0000:0002:0000:0000:0000:0041]:3301, the HPACK algorithm will convert the above field into a binary code stream with a total length of 58 bytes after recognizing the first header field for the first time, and store the corresponding encoding index value Index 65 in the dynamic table. After recognizing the first header field as http: / / [240a:0000:0000:0002:0000:0000:0000:0041]:3301 again, the field value of the first header field can be directly replaced with 0xc1 (0x80+65), without re-encoding the above first header field.

[0048] This compression algorithm can also be applied to scenarios where the SCP network element does not forward the service request packet between the service request network element and the target service response network element for the first time. That is, after decoding the first header field of the first service request packet, a pre-maintained dynamic table can be queried to determine the first network element address encoding index value corresponding to the first network element address. The first network element address in the decoded first header field can be replaced based on the first network element address encoding index value, without having to encode the first network element address again.

[0049] As mentioned above, the next-hop service response network element may be the target service response network element. In one embodiment of this disclosure, when the next-hop service response network element corresponding to the second network element address is the target service response network element, the service response data sent by the target service response network element is obtained, and the service response data is fed back to the service request network element through the SCP network element.

[0050] After forwarding the second service request packet to the next-hop service response network element corresponding to the second network element address, the second network element address encoding value corresponding to the second network element address is determined based on the second service request packet, and the second network element address encoding index value of the second network element address encoding value is determined. The second network element address encoding index value corresponds to the second network element address encoding value. For example, the second network element address encoding value is determined to be the second network element address encoding index value, or the second network element address encoding value is calculated according to a preset mapping algorithm to obtain the second network element address encoding index value. The preset mapping algorithm can be any mapping algorithm, such as a hash algorithm.

[0051] In the embodiments of this disclosure, after determining the second network element address encoding index value, the correspondence between the second network element address and the second network element address encoding index value is stored in a preset mapping table so that the second network element address encoding index value can be reused when forwarding data packets next time.

[0052] To more clearly describe the data forwarding process, the following example illustrates a scenario where an SCP network element forwards a service request based on the HTTP / 2 communication protocol. When making a service request based on HTTP / 2, the requesting network element is the Access and Mobility Management Function (AMF), and the target service response network element is the Session Management Function (SMF). The first header field includes the 3gpp-sbi-target-apiroot field, and the second header field includes the authority field. The network element address is identified by IP address and port number, as shown in the example below.

[0053] like Figure 4As shown, when the SCP network element forwards the service request packet between the service request network element and the target service response network element for the first time, the AMF communicates with the NRF to request the discovery of the second network element address of the SMF. The NRF feeds back the IP and port of the SMF. The AMF writes the IP and port of the SMF into the 3gpp-sbi-target-apiroot field of the first service request packet before encoding, fills the IP and port of the SCP network element into the authority field, encodes the first service request packet to generate the encoded first service request packet codemsg1, and sends codemsg1 to the SCP network element.

[0054] The SCP network element decodes `codemsg1` to obtain the string `string1`. It extracts the SMF's IP address and port from the decoded `3gpp-sbi-target-apiroot` field. The SCP network element then looks up its internal routing table to find the IP address and port of the next-hop service response network element for the SMF network element. If the SMF network element and SCP network element are directly connected, the IP address and port of the next-hop service response network element sent by the SCP network element to the SMF network element are the SMF network element's own IP address and port. Therefore, when the SCP network element forwards the request, the `authority` value should be filled with the SMF network element's IP address and port. The SCP network element modifies the `authority` field in the HTTP / 2 header, filling it with the IP address and port of the next-hop service response network element for the SMF network element, resulting in `string2`. The SCP then re-encodes `string2` to generate `codemsg2`. In this embodiment, a pre-defined mapping table also stores the correspondence between the encoded value of the `authority` field (`codetext1`) and the IP address and port of the next-hop service response network element. Finally, the SCP network element sends `codemsg2` to the next-hop service response network element.

[0055] like Figure 5 As shown, when the SCP network element forwards the service request packet between the service request network element and the target service response network element for the first time, the AMF network element calls the NF discovery service of the NRF network element to request the discovery of the SMF. The NRF returns the IP and port of the SMF. The AMF writes the IP and port of the SMF into the 3gpp-sbi-target-apiroot field of the first service request packet before encoding, fills the IP and port of the SCP network element into the authority field, encodes the first service request packet to generate the encoded first service request packet codemsg3, and sends codemsg3 to the SCP network element.

[0056] The SCP network element decodes the 3gpp-sbi-target-apiroot field in codemsg3, identifies the IP and port of the SMF, looks up the routing table to obtain the IP and port of the next-hop response network element destined for the SMF network element, queries the preset mapping table based on the IP and port of the next-hop response network element, determines the corresponding codetext1, and can replace the authority field in codemsg3 with codetext1 based on the pre-recorded field position of codetext1 to obtain codemsg4. Then, the SCP network element sends codemsg4 to the next-hop service response network element.

[0057] Therefore, in the above embodiments, the complete request packet needs to be parsed and encoded only during the first forwarding. In the second and subsequent forwarding processes, only the 3gpp-sbi-target-apiroot field needs to be parsed. Moreover, the pre-defined mapping table is used to replace re-encoding, which greatly improves the forwarding efficiency. When the SCP network element forwards the service request packet corresponding to HTTP2 to the next-hop service response network element, if the network element address of this next-hop service response network element appears for the first time, the entire service request packet is parsed, the HTTP2 header is modified, re-encoded, and sent to the next hop. The correspondence between the network element address encoding index value and the network element address corresponding to the modified field (second header field) is recorded.

[0058] When an SCP network element forwards a service request packet corresponding to HTTP / 2 to the next-hop service response network element, if the network element address of this next-hop service response network element is not appearing for the first time, it queries a preset mapping table, replaces the original field value with the network element address encoding index value recorded in the preset mapping table, and then sends it to the next hop. Compared with the first forwarding, subsequent forwardings do not need to parse the complete service request data packet or re-encode it, reducing the computing power consumption of the SCP network element.

[0059] In summary, the data forwarding processing method of this disclosure embodiment obtains an encoded first service request packet sent by a service requesting network element. The header field of the first service request packet includes a first header field and a second header field. The first header field corresponds to the first network element address of the target service response network element, and the second header field corresponds to the second network element address of the next-hop service response network element. The first header field is decoded to obtain the first network element address, and the second network element address of the next-hop service response network element is determined based on the first network element address. A preset mapping table is queried to determine whether a second network element address encoding index value corresponding to the second network element address is included. If the second network element address encoding index value is included, the initial field value of the second header field is updated to the second network element address encoding index value, and the updated first service request packet is forwarded to the next-hop service response network element corresponding to the second network element address. This technical solution reduces the computational power consumption of SCP forwarding data and improves the performance of the SCP network element.

[0060] To implement the above embodiments, this disclosure also proposes a data forwarding processing apparatus. The data forwarding processing apparatus is applied in a Service Proxy (SCP) network element. Figure 6 This is a schematic diagram of the structure of a data forwarding processing apparatus according to an embodiment of the present disclosure, as shown below. Figure 6 As shown, the data forwarding processing device includes a memory 610, a transceiver 620, and a processor 630. The memory 610 is used to store computer programs; the transceiver 620 is used to send and receive data under the control of the processor 630.

[0061] Processor 630 is used to read computer programs from memory and perform the following operations:

[0062] Obtain the encoded first service request packet sent by the service request network element. The header field of the first service request packet contains a first header field and a second header field. The first header field corresponds to the first network element address of the target service response network element, and the second header field corresponds to the second network element address of the next-hop service response network element.

[0063] Decode the first header field to obtain the first network element address, and determine the second network element address of the next-hop service response network element based on the first network element address;

[0064] Query the preset mapping table to determine whether it contains the second network element address encoding index value corresponding to the second network element address;

[0065] When the second network element address encoding index value is included, the initial field value of the second header field is updated to the second network element address encoding index value, and the updated first service request packet is forwarded to the next-hop service response network element corresponding to the second network element address.

[0066] Among them, Figure 6In this context, the bus architecture can include any number of interconnected buses and bridges, specifically linking various circuits together, represented by one or more processors (represented by a processor) and memories (represented by memory). The bus architecture can also link together various other circuits such as peripheral devices, voltage regulators, and power management circuits, which are well known in the art and therefore will not be described further herein. The bus interface provides an interface. The transceiver 620 can be multiple elements, including transmitters and receivers, providing a unit for communicating with various other devices over transmission media, including wireless channels, wired channels, optical fibers, etc. The processor is responsible for managing the bus architecture and general processing, and the memory 610 can store data used by the processor 630 during operation.

[0067] The processor 630 can be a central processing unit (CPU), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or a complex programmable logic device (CPLD). The processor can also adopt a multi-core architecture.

[0068] In one embodiment of this disclosure, before decoding the first header field to obtain the first network element address, the processor is further configured to:

[0069] It is determined that the SCP network element is not the network element that first forwards the service request packet between the target service response network element and the network element that first forwards the service request.

[0070] In one embodiment of this disclosure, the processor is further configured to:

[0071] When determining that the SCP network element is the service request packet between the network element that first forwards the service request and the target service response network element, the first service request packet is decoded to obtain the decoded service request string.
