Fig. 2 is a flow chart schematically illustrating an acquisition method for service data, in accordance with some embodiments of the present disclosure.
In step S202, the ue accesses the ICN network and sends a service request message to an ICN-GW (Information Centric Networking Gateway). The service request message includes a service name corresponding to the requested service data. Thus, the user equipment does not use the IP address information of the user equipment when sending the service request message, thereby being capable of releasing the association between the service request message and the IP address.
In step S204, the ICN-GW forwards the service request message to the corresponding uplink classifier according to the service name and the stored first FIB (Forwarding Information Base) Information Table, and adds corresponding first Forwarding record Information in the first PIT Table, when the cached CS (Content Store, Content cache) Information and the stored first PIT Table (Pending Interest Table) do not include the service name.
For example, after receiving the service request message sent by the user equipment, the ICN-GW determines whether the cached CS information includes the service name of the service request message, that is, determines whether the cached CS information includes the service data requested by the service request message, or may be understood as whether the ICN-GW determines whether the service data requested by the service request message is cached before receiving the service request message. If the cached CS information does not include the service name of the service request message, the ICN-GW further determines whether the first PIT table includes the service name of the service request message, i.e., determines whether there is currently a service request identical to the service request message. If the same service request message does not exist in the first PIT table, the ICN-GW forwards the service request message to the upstream classifier.
In some embodiments, the first FIB information table includes a forwarding path from the ICN-GW to an edge cloud platform capable of providing the requested service data.
For example, the ICN-GW may forward the service request message to the corresponding upstream classifier according to the service name and a forwarding path corresponding to the service name (i.e., a forwarding path from the ICN-GW to an edge cloud platform capable of providing the requested service data), and add corresponding first forwarding record information in the first PIT table. Here, the first forwarding record information includes the service request message, and may be used to prevent the same service request message from being forwarded multiple times.
In step S206, the uplink classifier forwards the service request message to the corresponding edge cloud platform in an ICN packet data manner according to the service name and the stored second FIB information table, and adds corresponding second forwarding record information to the stored second PIT table.
In some embodiments, the second FIB information table includes a forwarding path from the upstream classifier to an edge cloud platform capable of providing the requested service data.
The following describes, with reference to a specific embodiment, that the uplink classifier forwards the service request message to the corresponding edge cloud platform in an ICN packet data manner.
For example, the uplink classifier first groups the service request message, and divides the service request message into ICN packet data units for transmission, where the ICN packet data units include a service name of the requested service data, information of the user equipment, and the like. Here, the information of the user equipment may include identification information of the requesting terminal, i.e., identity information for identifying the requesting terminal, and may be used to determine the terminal requesting the service data. And then forwarding the service request message to the corresponding edge cloud platform according to the service name and a forwarding path corresponding to the service name (namely, a forwarding path from the uplink classifier to the edge cloud platform capable of providing the requested service data), and adding corresponding second forwarding record information in the stored second PIT table. Where the second forwarding record information includes the service request message, it may be used to avoid that the same service request message is forwarded multiple times.
In some embodiments, the respective edge cloud platform may comprise the edge cloud platform closest in distance to the user device. The service request message is dredged to the edge cloud platform closest to the user equipment, so that service data can be provided nearby, and delay time caused by transmission distance is reduced.
In some embodiments, if the location of the user device changes, the corresponding edge cloud platform may include an edge cloud platform with which a connection has been established with the user device prior to the location change. The service request message is dredged to the edge cloud platform, connection with other edge cloud platforms is not required to be established again, cost can be reduced, and unstable service caused by replacement of the edge cloud platform can be avoided.
In step S208, the edge cloud platform processes the service request message according to the service name in the service request message by using the corresponding network function module to generate a service response message, and returns the service response message to the uplink classifier in an ICN packet data manner, where the service response message includes service data corresponding to the service name.
In step S210, the uplink classifier buffers the service data in the service response message and forwards the service response message to the ICN-GW.
The ICN-GW buffers the service data in the service response message and forwards the service response message to the user equipment at step S212.
Thus, there is provided an acquisition method for service data according to some embodiments of the present disclosure. The user equipment transmits a service request message containing a service name corresponding to the requested service data to the ICN-GW. The ICN-GW forwards the service request message to an uplink classifier. And then the data is forwarded to the corresponding edge cloud platform by the uplink classifier. And the edge cloud platform processes the service request message by utilizing the corresponding network function module to return a service response message corresponding to the service request message. The ICN network-based service data acquisition method is realized. This method is different from an acquisition method for service data based on a TCP/IP architecture in the related art. The service data acquisition method based on ICN deployment can provide better mobility support. In the acquisition method of the embodiment of the disclosure, the service data may be acquired based on the service name, and the connection with the new edge cloud platform may not be established based on the IP address information of the user equipment.
In an edge computing system of a TCP/IP architecture in the related art, after a location of a service requester (user equipment) moves, the service requester may receive a service of an original edge cloud, but this way cannot guarantee that the service is still provided by a nearest edge cloud platform, which results in a large service delay.
In some embodiments, the method for acquiring service data may further include: when the CS information includes a service name, the ICN-GW returns service data corresponding to the service name to the user equipment. For example, when the user equipment sends a service request message to the network node ICN-GW, the ICN-GW returns the server data directly to the user equipment if it has cached the service data corresponding to the service name.
In the above embodiments, the ICN-GW has a caching capability. When the service data requested by the user equipment is cached in the ICN-GW, the ICN-GW can directly return the cached requested service data to the user equipment. Therefore, the time delay of the same service request can be reduced, the real-time service requirement is met, and the user experience of hot service in the network is improved.
In other embodiments, the upstream classifier may also have a buffering capability to buffer service data that has been requested. In this way, the uplink classifier can also directly return the buffered requested service data to the user equipment, thereby reducing the delay of the same service request.
In some embodiments, the method for acquiring service data may further include: the ICN-GW does not forward the service request message to the upstream classifier when the CS information does not include the service name and the first PIT table includes the service name. Here, the first PIT table contains the service name, which indicates that the service request message has been forwarded by the ICN-GW before, so here the ICN-GW may no longer forward the service request message to the upstream classifier. This may avoid the same service request message being forwarded multiple times.
In some embodiments, the method for acquiring service data may further include: and the ICN-GW forwards the service request message to other edge cloud platforms in the ICN network or other ICN networks to acquire corresponding service data under the condition that the current edge cloud platform cannot provide the requested service data.
For example, in a case where the edge cloud platform closest to the user equipment cannot provide the requested service data, the ICN-GW may groom the service request message to other edge cloud platforms or other ICN networks for corresponding processing. Therefore, the user equipment can be ensured to normally acquire the requested service data.
It should be noted here that, if other edge cloud platforms or other ICN networks need to receive the service request message in the form of IP packet data, the ICN-GW divides and encapsulates the service request message into IP packet data units, and then completes the forwarding. Here, the IP packet data unit includes IP address information of the transmitting node and the receiving node. If other edge cloud platforms or other ICN networks need to receive the service request message in an ICN packet data mode, the ICN-GW divides the service request message and encapsulates the service request message into an ICN packet data unit, and then the forwarding is achieved.
In some embodiments, the ICN-GW and the uplink classifier, etc. may forward according to their stored FIB information, forwarding policy, user selection, etc. Services which can be provided by the adjacent edge cloud platform can be directly forwarded to the edge cloud platform for processing; and for the request which needs to be forwarded to other edge cloud platforms in the ICN network or other ICN networks, forwarding the request to other edge cloud platforms in the ICN network or other ICN networks.
In some embodiments, the method for acquiring service data may further include: and after forwarding the service response message to the ICN-GW, the uplink classifier clears the second forwarding record information in the second PIT table. Here, the second forwarding record information is cleared to indicate that the upstream classifier has not currently forwarded the above-mentioned service request message.
In some embodiments, the method for acquiring service data may further include: and the ICN-GW clears the first forwarding record information in the first PIT table after forwarding the service response message to the user equipment. Here, the first forwarding record information is cleared to indicate that there is no service request message currently being forwarded as described above.
In some embodiments, the step of the user equipment accessing the ICN network may comprise the steps of:
first, the user equipment transmits an Access request message to an AMF (Access and Mobility Management Function). The reception request message contains identification information of the user equipment. The identification information of the user equipment may include, for example: SUCI (Subscription conditional Identifier) or 5G-GUTI (5G Global Unique temporal Identity, 5G).
Next, the AMF performs an authentication operation on the user equipment according to the identification information of the user equipment, and sends an authentication success message to an SMF (Session Management Function) after the authentication is successful. The authentication success message includes identification information of the user equipment.
And then, after receiving the authentication success message, the SMF configures the network element in the ICN network and returns a session establishment message to the user equipment according to the identification information of the user equipment. The session setup message includes the configured network element information. The network element information configured here includes: session information and related forwarding rule information configured by a user plane Network element (e.g., ICN-GW, uplink classifier, etc.), and session information configured at a RAN (Radio Access Network).
And then, after receiving the session establishment message, the user equipment is connected with the configured network element, thereby accessing the ICN network.
In the above embodiment, the ue accesses the ICN network through the AMF and the SMF, and may establish a session message with the ICN network, so as to subsequently perform the above method for acquiring service data.
In some embodiments, the method for acquiring service data may further include: before user equipment accesses an ICN (integrated circuit network), the edge cloud platform sends a registration request message to a network element of the ICN, wherein the registration request message comprises service data which can be provided by the edge cloud platform and position information of the edge cloud platform; and after receiving the registration request message, the network element of the ICN records service data which can be provided by the edge cloud platform and position information of the edge cloud platform, establishes a corresponding FIB information table in each ICN-GW in the ICN, and returns a registration success message to the edge cloud platform.
In the embodiment, the process of registering the edge cloud platform with the ICN network is realized. Before the user equipment accesses the ICN, the edge cloud platform reports the service data and the position information which can be provided to a network element of the ICN, and the subsequent ICN-GW and the uplink classifier can reasonably distribute the service request message of the user equipment to the most appropriate edge cloud platform or other ICN according to the information so as to acquire the requested corresponding service data.
Fig. 3 is a flow chart that schematically illustrates an acquisition method for service data, in accordance with further embodiments of the present disclosure.
In step S302, the edge cloud platform registers in the ICN network. For example, before the user equipment sends the service request message to the ICN network, the edge cloud platform registers with a network element (e.g., a UDM (Unified Data Management) network element), thereby informing the network element of the service Data that can be provided and the location information of the edge cloud platform. The ICN network establishes corresponding records and establishes corresponding FIB information tables in each ICN-GW.
In step S304, the user equipment accesses the ICN network. For example, the user equipment may access the ICN network by the methods described above. The type of connection thus established between the user equipment and the network is the ICN network type. The user equipment may send related messages required when establishing the connection to the access network and the uplink classifier.
In step S306, the user equipment sends a service request message to the ICN-GW. The service request message includes a service name corresponding to the requested service data.
In step S308, the ICN-GW processes the service request message sent by the ue, that is, determines whether the cached CS information and the stored first PIT table include the service name of the service request message, and makes a corresponding operation response according to different determination results. The following description will be made with specific reference to the following three cases.
In the first case, the ICN-GW determines that the CS information includes the service name of the service request message, and then performs step S310, that is, transmits the cached service data corresponding to the service request message to the user equipment.
In the second case, the ICN-GW determines that the CS information does not include the service name of the service request message, but the first PIT table includes the service name of the service request message, then the ICN-GW performs step S312, i.e., suspends forwarding of the service request message.
In the third case, if the ICN-GW determines that the CS information does not include the service name of the service request message and the first PIT table does not include the service name of the service request message, the ICN-GW performs step S314, i.e., forwards the service request message to the corresponding uplink classifier. The detailed description of this step can refer to step S204.
In step S316, the uplink classifier forwards the service request message to the corresponding edge cloud platform in an ICN packet data manner, which may refer to step S206.
In step S318, the edge cloud platform forwards the service request message to the corresponding network function module according to the service name in the service request message for processing. For example, the edge cloud platform forwards the service request message to an NEF (Network Exposure Function) module according to the service name for processing. Here, a plurality of network function modules (i.e., service function modules) are deployed on the edge cloud platform, and each network function module may provide corresponding service data. After being forwarded to the edge cloud platform, a certain service request message can be processed by a corresponding network function module according to a requested service name. For example, a video service module may be deployed on the edge cloud platform, and the relevant video request may be processed by the video service module of the edge cloud platform.
In step S320, the network function module processes the service request message to generate a service response message, and sends the service response message to the edge cloud platform. For example, the NEF processes the service request message to generate a service response message, and feeds back the service response message to the edge cloud platform. The service response message may contain a data packet processed by the network function module.
It should be noted here that the network function module is deployed on the edge cloud platform, and thus, the network function module is a part of the edge cloud platform. The network function module provides service data, namely the edge cloud platform provides service data. The network function module generates a service response message, that is, the edge cloud platform generates a service response message by using the corresponding network function module.
In step S322, the edge cloud platform sends a service response message to the upstream classifier.
In step S324, the uplink classifier buffers the service data and forwards the service response message. For example, the uplink classifier queries the second PIT table according to the service name, caches the service data in the service response message, and forwards the service response message to the ICN-GW in an ICN packet data manner from the corresponding port according to the second forwarding record information in the second PIT table. In addition, the uplink classifier clears the second forwarding record information stored in the second PIT table after the forwarding is finished.
The ICN-GW buffers and forwards the service response message at step S326. For example, the ICN-GW queries a first PIT table according to the service name, caches the service data in the service response message, and forwards the service response message to the user equipment from a corresponding port in an ICN packet data manner according to the first forwarding record information in the first PIT table. In addition, the ICN-GW clears the first forwarding record information stored in the first PIT table after the forwarding is finished.
Thus, there is provided methods for acquisition of service data according to further embodiments of the present disclosure. Because the network nodes such as the ICN-GW and the uplink classifier have the caching capability, when the service data requested by the user equipment is cached in the network nodes such as the ICN-GW and the uplink classifier, the network nodes such as the ICN-GW and the uplink classifier can directly return the cached requested service data to the user equipment. Therefore, the time delay of the same service request can be reduced, the real-time service requirement is met, and the user experience is improved.
The ICN network names the service content provided by the network and routes and forwards the packet according to the content/service name carried in the packet. The ICN network may support deep sensing and intelligent caching of content/services by the network (i.e., a cache node in the ICN may cache service content data according to service characteristics, network caching policies, etc., and use the cached data to serve subsequent identical service requests), and may better achieve load balancing of the network. In addition, compared with a TCP/IP system architecture in the related art, the information center network realizes the decoupling of the identity and the position in the network and can provide better mobility support.
Furthermore, in the edge computing system of the TCP/IP architecture of the related art, after the location of the service requester moves, the service requester may need to establish a connection with a new edge computing platform closest to the new location to acquire the service. This approach requires the establishment of a new connection and therefore the overhead of establishing a connection. When the switching frequently occurs, because the edge computing system based on the TCP/IP architecture adopts the connected mode, the frequent switching may cause the connection between the user equipment and the network to be interrupted, and the connection needs to be re-established to continue transmitting the service data, thereby making it difficult to ensure the stability of providing the service. In the embodiment of the present disclosure, the edge computing system based on the ICN architecture adopts a connectionless mode, and the user equipment may obtain the service data by resending the service request message, so that the stability of providing the service may be improved.

FIG. 5 is a block diagram that schematically illustrates an acquisition system for service data, in accordance with further embodiments of the present disclosure.
As shown in fig. 5, the system for acquiring service Data in this embodiment includes a User equipment 501, (R) AN (Radio) Access Network 502, AN uplink classifier 503, AN ICN-GW and UPF (User Plane Function) 504, AN AMF505, AN SMF506, AN edge cloud platform 507, AN AF (Application Function) 508, AN ICN-DN (Information central Network-Data Network) 509, AN NSSF (Network Slice Selection Function) 510, AN AUSF (Authentication service Function) 511, AN UDM512, AN NEF513, and a PCF (Policy Control Function) 514. Here (R) AN502 may comprise part of the ICN-GW.
As shown in fig. 5, N1-N15 are interface reference points known to those skilled in the art in the mobile communication network, and are used to describe the connection relationship between network elements.
For example, N1 is an interface for connecting the user equipment 501 and the AMF 505. N2 is AN interface for connecting (R) AN502 with AMF 505. N3 is AN interface for connecting (R) AN502 and upstream classifier 503. N4 is an interface for connecting upstream classifier 503 and SMF 506. N5 is an interface for connecting AF508 and PCF 514. N6 is an interface for connecting the upstream classifier 503 and the edge cloud platform 507. N7 is an interface for connecting SMF506 and PCF 514. N8 is an interface for connecting AMF505 and UDM 512. N9 is an interface for connecting two UPFs. N10 is an interface for connecting SMF506 and UDM 512. N11 is an interface for connecting SMF506 and AMF 505. N12 is an interface for connecting AUSF511 and AMF 505. N13 is an interface for connecting AUSF511 and UDM 512. N14 is an interface for connecting two AMFs. N15 is an interface for connecting AMF505 and PCF 514. N22 is an interface for connecting AMF505 and NSSF 510.
The AMF505 may authenticate and authorize the user device 501 and the edge cloud platform 507. For example, the AMF505 supports the user equipment 501 and other terminals in the ICN network by enhancing the AMF network element, and allows the edge cloud platform 507 in the ICN network to perform application access to the user equipment.
The SMF506 may maintain a PDU (Packet Data Unit) session established between the user equipment 501 and the edge cloud platform 507 in the uplink classifier after the user equipment 501 completes authentication. For example, according to the characteristics of the ICN network, the SMF506 may forward the service request message of the user equipment 501 to the edge cloud platform 507 closest to the user equipment 501, and establish a corresponding PDU session. Here, the SMF506 may also push information of creation, deletion, etc. of the PDU session to the ICN-GW, i.e. the SMF506 maintains a PDU session message at the ICN-GW. SMF50 may also create forwarding state information (using FIBs, etc.) to ensure that ICN flows can be forwarded to the appropriate port when the network configures the ICN service, and may issue resource management policies (such as bandwidth, storage, caching policies, etc.) to the ICN-GW.
The uplink classifier 503 may classify the data information to be forwarded for transmission according to the service data requested by the user equipment 501 and the identification information of the user equipment 501. For example: the upstream classifier 503 may store therein relevant classification rules. After receiving the uplink data stream, the uplink classifier obtains the device identifier of the user equipment 501 and the requested service name, matches the device identifier with the classification rule, finds associated stream information, and forwards the stream to other devices (e.g., other ICN-GW or edge cloud platforms).
The ICN-GW may route and forward the service request message according to the service name corresponding to the service request data, and may cache the service data in the service response message. In case of receiving the service request message with the same service name as the service name, the ICN-GW may directly feed back the cached service data corresponding to the service request message to the user equipment 501, so as to reduce service latency. The ICN-GW may complete maintenance of the FIB with the assistance of SMF506 to ensure that packet forwarding of service request messages is achieved.
The AF508 may enable control capabilities for applications in the edge cloud platform. AF508 may interact with network elements such as PCF514, UDM512, etc. and change the policies and status information contained therein. The AF508 may also control and manage related services, etc. for the edge cloud platform. The AF508 may regulate service data traffic of the edge cloud platform, for example, through interactions with the SMF506 and AMF 505. The AF-ICN has the capability to communicate with the northbound interface, enabling richer network capabilities with NEF 13.
ICN-DN509 may be comprised of a number of ICN network nodes configured to provide network capabilities and application capabilities to the outside. For example, the network capability includes caching, multi-path transmission, mobility, and the like, and the application capability includes various network resources suitable for the application, such as storage, network state resources, and the like.
Further, UPF 504, NSSF510, AUSF511, and PCF514, etc., are functions known to those skilled in the art and will not be described in detail herein.
There has thus been provided an acquisition system for service data according to further embodiments of the present disclosure. The above system designed based on the ICN architecture can provide better mobility support. In addition, because the network nodes such as the ICN-GW and the uplink classifier in the system have caching capability, when the service data requested by the user equipment is cached in the network nodes such as the ICN-GW and the uplink classifier, the network nodes such as the ICN-GW and the uplink classifier can directly return the cached requested service data to the user equipment. Therefore, the time delay of the same service request can be reduced, the real-time service requirement is met, and the user experience of hot service in the network is improved.
