Description

Technical Field

[0001] The present invention relates to the field of network communication technology, and in particular to a computing power perception method and system for a mobile computing power network. Background Art

[0002] The mobile computing network is based on mobile network capabilities and infrastructure, and is an open computing network infrastructure composed of 5G-A / 6G network architecture and computing resources. It introduces unified scheduling of networks and computing power, fully utilizing computing resources such as terminal computing power, base station computing power, and edge computing power. Computing power scheduling improves the experience of 5G access services, optimizes the computing network experience of end-to-end services, and increases the utilization rate of mobile computing network resources, achieving synergy between mobile networks and computing power. In addition, mobile networks naturally support the mobility of end users and provide efficient scheduling and QoS assurance capabilities for services in mobile mode based on the mobility management and session management capabilities of the core network and wireless access network. Therefore, after incorporating computing power factors, the mobile computing network can provide mobile connectivity capabilities that are coordinated with computing networks through appropriate innovation.

[0003] Computing power perception is the prerequisite for the coordinated and unified orchestration and scheduling of computing power. When mobile communication network nodes (such as terminals and base stations) act as computing power providers, they need to register their own computing power capabilities in the mobile computing power network and support real-time updates of computing power. The mobile computing power network perceives information about computing power nodes and computing power services on the nodes, such as the computing power resource type and computing power service type on the nodes, providing a reference for the subsequent unified orchestration of computing network resources.

[0004] Existing computing power awareness solutions (including computing power registration and updating) are primarily targeted at bearer networks. Bearer networks and mobile communication networks differ significantly in terms of architecture, interfaces, and communication protocols, making these solutions inappropriate for mobile communication networks. One current implementation for mobile computing power networks involves adding a computing power registration center to the core network. By expanding the control plane N1 (NAS) and N2 (NGAP) interfaces, the UE uses the Register N1 message to report its computing power information to the computing power registration center, and the base station uses the NG Establish N2 message to report this information. This solution requires significant changes to the 3GPP standard interface, making it difficult to standardize and scale its application.

[0005] How to achieve computing power perception in mobile computing power networks while reducing changes to existing 3GPP standard interfaces is a technical problem that needs to be solved. Summary of the Invention

[0006] The technical task of the present invention is to address the above shortcomings and provide a computing power perception method for a mobile computing power network to solve the problems of the computing power perception method for a mobile computing power network.

[0007] In a first aspect, the present invention provides a computing power perception method for a mobile computing power network, which is applied between a terminal, a base station, and a core network, wherein an N6 interface exists between a user plane of the core network and a computing power registration center. The method comprises the following steps:

[0008] Terminal registration update: The terminal sends a registration request message to the core network, and executes the terminal registration process of the 3GPP protocol based on the registration request message, wherein the registration request message carries an indication for indicating whether the terminal is a computing power node. The core network stores the indication in the registration request message in the context of the terminal. After executing the terminal registration process, the terminal sends a PDU session establishment request message to the core network. If the terminal is a computing power node, the PDU session establishment request message carries a request for requesting the IP address of the computing power registration center. The core network returns a PDU session establishment accept message to the terminal. The PDU session establishment accept message carries the IP address of the computing power registration center. After the PDU session is established, the PDU session update process is executed to establish a dedicated QoS flow for transmitting terminal computing power information. The terminal reports and updates its computing power information to the computing power registration center through the user plane and using the application layer protocol to realize the registration and update of terminal-side computing power information;

[0009] Base station link establishment and update: The base station sends an NG establishment request message to the core network. The NG establishment request message carries an indication of whether the base station is a computing power node. The core network returns an NG establishment response message to the base station. If the base station is a computing power node, the NG establishment response message carries the IP address of the computing power registration center. The base station reports and updates its computing power information to the computing power registration center through the user plane and the application layer protocol to realize the registration and update of the computing power information on the base station side.

[0010] Preferably, for the terminal, the indication in the registration request message indicating whether the terminal is a computing power node is carried by the terminal capability information element. For the terminal serving as a computing power node, the PDU session establishment request message is used to request the IP address of the computing power registration center and is carried by the protocol configuration option information element in the terminal-to-network direction. The IP address of the computing power registration center in the PDU session establishment acceptance message is returned by the protocol configuration option information element in the network-to-terminal direction.

[0011] Preferably, for the base station, the indication in the NG establishment request message for indicating whether the base station is a computing power node is carried by the reported broadcast PLMN item information element, and for the base station serving as a computing power node, the IP address of the computing power registration center in the NG establishment response message is carried by the PLMN support item information element.

[0012] Preferably, for terminals and base stations that serve as computing power nodes, when the computing power nodes report and update their computing power information to the computing power registration center through the user plane and using the application layer protocol, if the HTTP / HTTPS protocol is adopted, the computing power nodes register the computing power information through the POST method and update the computing power information through the PUT method. When the base station and terminal no longer serve as computing power nodes, their computing power information is deleted through the DELETE method.

[0013] In a second aspect, the present invention provides a mobile network computing power network system, including a terminal, a base station, a core network, and a computing power registration center, wherein an N6 interface exists between a user plane of the core network and the computing power registration center;

[0014] During the terminal registration update phase, the terminal is used to send a registration request message to the core network. Based on the registration request message, the terminal and the core network cooperate to execute the terminal registration process of the 3GPP protocol, wherein the registration request message carries an indication for indicating whether the terminal is a computing power node, and the core network is used to store the indication in the registration request message in the context of the terminal. After executing the terminal registration process, the terminal is used to send a PDU session establishment request message to the core network. If the terminal is a computing power node, the PDU session establishment request message carries a request for requesting the IP address of the computing power registration center. The core network is used to return a PDU session establishment acceptance message to the terminal. The PDU session establishment acceptance message carries the IP address of the computing power registration center. After the PDU session is established, the terminal and the core network cooperate to execute the PDU session update process and establish a dedicated QoS flow for transmitting terminal computing power information. The terminal reports and updates its computing power information to the computing power registration center through the user plane and using the application layer protocol to realize the registration and update of the terminal-side computing power information;

[0015] During the base station link establishment and update phase, the base station is used to send an NG establishment request message to the core network. The NG establishment request message carries an indication of whether the base station is a computing power node. The core network is used to return an NG establishment response message to the base station. If the base station is a computing power node, the NG establishment response message carries the IP address of the computing power registration center. The base station reports and updates its computing power information to the computing power registration center through the user plane and the application layer protocol to realize the registration and update of the computing power information on the base station side.

[0016] Preferably, for the terminal, the indication in the registration request message indicating whether the terminal is a computing power node is carried by the terminal capability information element. For the terminal serving as a computing power node, the PDU session establishment request message is used to request the IP address of the computing power registration center and is carried by the protocol configuration option information element in the terminal-to-network direction. The IP address of the computing power registration center in the PDU session establishment acceptance message is returned by the protocol configuration option information element in the network-to-terminal direction.

[0017] Preferably, for the base station, the indication in the NG establishment request message for indicating whether the base station is a computing power node is carried by the reported broadcast PLMN item information element, and for the base station serving as a computing power node, the IP address of the computing power registration center in the NG establishment response message is carried by the PLMN support item information element.

[0018] Preferably, for terminals and base stations that serve as computing power nodes, when the computing power nodes report and update their computing power information to the computing power registration center through the user plane and using the application layer protocol, if the HTTP / HTTPS protocol is adopted, the computing power nodes register the computing power information through the POST method and update the computing power information through the PUT method. When the base station and terminal no longer serve as computing power nodes, their computing power information is deleted through the DELETE method.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments given are not intended to limit the present invention. Unless there is a conflict, the embodiments of the present invention and the technical features in the embodiments may be combined with each other.

[0025] The embodiments of the present invention provide a computing power perception method and system for a mobile computing power network, which are used to solve the technical problem of how to achieve computing power perception in a mobile computing power network while reducing changes to the 3GPP standard interface.

[0026] Example 1:

[0027] The present invention provides a computing power perception method for a mobile computing power network, which is applied between a terminal, a base station, and a core network. An N6 interface exists between the core network user plane and a computing power registration center. The method of this embodiment includes two steps: terminal registration update and base station link establishment update.

[0028] Terminal registration update: The terminal sends a registration request message to the core network, and executes the terminal registration process of the 3GPP protocol based on the registration request message, wherein the registration request message carries an indication for indicating whether the terminal is a computing power node. The core network stores the indication in the registration request message in the context of the terminal. After executing the terminal registration process, the terminal sends a PDU session establishment request message to the core network. If the terminal is a computing power node, the PDU session establishment request message carries a request for requesting the IP address of the computing power registration center. The core network returns a PDU session establishment acceptance message to the terminal. The PDU session establishment acceptance message carries the IP address of the computing power registration center. After the PDU session is established, the PDU session update process is executed to establish a dedicated QoS flow for transmitting terminal computing power information. The terminal reports and updates its computing power information to the computing power registration center through the user plane using the application layer protocol to realize the registration and update of terminal-side computing power information.

[0029] In this embodiment, for a terminal, the indication in the registration request message indicating whether the terminal is a computing power node is carried by the terminal capability information element. If the terminal is a computing power node, the PDU session establishment request message is used to request the IP address of the computing power registration center and is carried by the protocol configuration option (PCO) information element in the terminal-to-network direction. The IP address of the computing power registration center in the PDU session establishment acceptance message is returned by the protocol configuration option (PCO) information element in the network-to-terminal direction.

[0030] Base station link establishment and update: The base station sends an NG establishment request message to the core network. The NG establishment request message carries an indication of whether the base station is a computing power node. The core network returns an NG establishment response message to the base station. If the base station is a computing power node, the NG establishment response message carries the IP address of the computing power registration center. The base station reports and updates its computing power information to the computing power registration center through the user plane and the application layer protocol to realize the registration and update of the computing power information on the base station side.

[0031] In this embodiment, for the base station, the indication in the NG establishment request message indicating whether the base station is a computing power node is carried by the reported broadcast PLMN item information element. If the base station is a computing power node, the IP address of the computing power registration center in the NG establishment response message is carried by the PLMN support item information element.

[0032] In the method disclosed in this embodiment, there is an N6 interface between the computing power registration center and the UPF. The terminal reports whether it is a computing power node in the registration message. For the computing power terminal, the core network sends the IP address of the computing power registration center when the PDU session is established. The terminal and the computing power registration center communicate through the application layer protocol (such as HTTP, HTTPS, SIP, etc.), including the registration and update of the computing power information on the terminal side; for the base station, the computing power base station is reported in the NG establishment message, and the IP address of the computing power registration center is obtained through the response message. Then, the computing power information is reported to the computing power registration center using the application layer protocol.

[0033] In this embodiment, for terminals and base stations that serve as computing power nodes, when the computing power nodes report and update their computing power information to the computing power registration center through the user plane and using the application layer protocol, if the HTTP / HTTPS protocol is adopted, the computing power nodes register the computing power information through the POST method and update the computing power information through the PUT method. When the base station and terminal no longer serve as computing power nodes, their computing power information is deleted through the DELETE method.

[0034] Based on the computing power perception method disclosed in this embodiment, Figure 1 and Figure 2 As shown, the specific operation steps of terminal registration update and base station link establishment update are given.

[0035] The terminal computing power registration and computing power update process includes the following steps, as follows:

[0036] Step 1: The terminal sends a Registration Request (NAS) message to the AMF through NG-RAN. The 5GMMcapabilityIE in the message carries an indication of whether it is a computing power node.

[0037] 5GMMcapabilityIE is used to provide UE-related capability information to the network and is indicated in the form of a Bitmap. In this embodiment, 1 bit is used in the existing idle bits to indicate whether it is used as a computing power node.

[0038] Step 2: Refer to section 4.2.2.2.2 of 3GPP TS 23.502 and perform the UE initial registration procedure. The AMF stores the computing node indication in the UE context.

[0039] Step 3: The UE sends a PDU session establishment request (PDUSessionEstablishmentRequest) NAS message to the AMF through the NG-RAN to request the establishment of a PDU session. The message carries the protocol configuration option (PCO) / ePCO information and requests the IP address of the computing power registration center from the network side.

[0040] PCO / ePCO is used to provide the UE with some additional information related to the network it is connected to. The AdditionalParameters list of this IE contains a dedicated parameter container. In this embodiment, in the terminal-to-network direction, a protocol-reserved container identifier value is used to request the IP address of the computing power registration center from the network.

[0041] Step 4: AMF sends Nsmf_PDUSession_CreateSMContext Request to SMF, carrying the N1 SMcontainer containing the PDUSessionEstablishmentRequest message and the UE's computing node indication;

[0042] Step 5: SMF interacts with UDM to obtain UE's session management subscription data;

[0043] Step 6: SMF verifies the computing node identity of the UE, responds to its PCO request, and returns Nsmf_PDUSession_CreateSMContext Response to AMF, which carries the IP address of the computing registration center;

[0044] SMF can obtain the IP address of the computing power registration center through pre-configuration or signaling interaction.

[0045] Step 7: Refer to Section 4.3.2.2.1 of 3GPP TS 23.502 and continue with the PDU session establishment process.

[0046] Step 8: The AMF returns a PDU Session Establishment Accept message to the UE, which corresponds to the PCO / ePCO request parameter in the PDU Session Establishment Request message. The IP address of the computing power registration center is provided to the UE as part of the PCO / ePCO.

[0047] Step 9: Refer to Section 4.3.3.2 of 3GPP TS 23.502 and execute the PDU session update process to establish a dedicated QoS flow for transmitting computing power information.

[0048] Considering that after the terminal completes the computing power registration, the subsequent computing power information update is intermittent, and the computing power registration and update information belong to high-priority signaling, preferably, the QoS flow is of non-GBR type and uses the same 5QI value as IMS signaling (5QI=5).

[0049] Step 10: The terminal reports computing power information to the computing power registration center through the user plane using application layer protocols (such as HTTP, HTTPS, SIP, etc.). The computing power measurement method is not defined and may include information such as node identification, node type, computing power type, computing resources, storage resources, and remaining power.

[0050] Preferably, the application layer protocol is recommended to use HTTP / HTTPS protocol, and the terminal uses the POST method to register its own computing power information with the computing power registration center.

[0051] Step 11: The computing power registration center returns a 200OK status code, indicating that the terminal computing power information is successfully registered;

[0052] Step 12: If the terminal meets the computing power information update conditions, such as computing resources decreasing by a preset percentage, the terminal uses the PUT method to update the computing power information to the computing power registration center;

[0053] Step 13: The computing power registration center returns a 200OK status code, indicating that the terminal computing power information is updated successfully.

[0054] If a terminal no longer serves as a computing power node (e.g., due to insufficient remaining battery power), it can use the HTTP / HTTPS DELETE method to notify the computing power registration center to delete its computing power information, and will no longer participate in computing power scheduling. It can then re-register for computing power after its computing power capacity is restored.

[0055] The registration and update process of the base station computing power node includes the following operations:

[0056] Step 0: AMF obtains the IP address of the computing power registration center through pre-configuration, signaling interaction with SMF, and querying NRF.

[0057] Step 1: NG-RAN sends an NGSetupRequest message to AMF to establish a connection between the two. The message carries an indication of whether it is a computing power node.

[0058] The computing power node indication can be carried under the Supported TA List—>Supported TA Item—>Broadcast PLMN List—>Broadcast PLMN Item IE of the message.

[0059] Step 2: AMF returns an NGSetupResponse to NG-RAN. For computing nodes, the message carries the IP address of the computing power registration center.

[0060] Similarly, the computing power registration center IP address can be carried under the PLMN Support List—>PLMN SupportItem IE of the message.

[0061] Step 3: NG-RAN uses application layer protocols (such as HTTP, HTTPS, SIP, etc.) to report computing power information to the computing power registration center. The computing power measurement method of the base station is not defined, and may include information such as node identification, node type, computing power type, computing resources, storage resources, etc.

[0062] Preferably, the application layer protocol is recommended to use HTTP / HTTPS protocol, and NG-RAN uses the POST method to register its own computing power information with the computing power registration center.

[0063] Step 4: The computing power registration center returns a 200OK status code, indicating that the base station computing power information is successfully registered;

[0064] Step 5: If the base station meets the computing power information update conditions, such as computing resources decreasing by a preset percentage, it uses the PUT method to update the computing power information to the computing power registration center;

[0065] Step 6: The computing power registration center returns a 200OK status code, indicating that the base station computing power information is updated successfully.

[0066] The computing power information exchanged between NG-RAN and the computing power registration center using the application layer can pass through the UPF, that is, reuse the N3 interface and GTP-U protocol between NG-RAN and UPF, and then reach the computing power registration center via the N6 interface. However, it should be noted that the GTP-U protocol carried by the N3 interface is UE-related. The user plane address (transport layer IP address and TEID) of the GTP-U tunnel is exchanged during the UE initial context establishment / PDU session resource establishment process. The computing power information transmitted between NG-RAN and UPF in this embodiment is not UE-related. The existing protocol process needs to be adaptively modified to transmit non-UE-related data. The modified process can be used in a variety of scenarios, not only for the computing power information transmission in this embodiment, but also for the perception data transmission between NG-RAN via UPF and SF (perception function) in the interawareness fusion scenario. The specific modification method is not described in this invention.

[0067] Example 2:

[0068] The present invention provides a mobile network computing power network system, including a terminal, a base station, a core network and a computing power registration center, wherein an N6 interface exists between the core network user plane and the computing power registration center.

[0069] During the terminal registration update phase, the terminal is used to send a registration request message to the core network. Based on the registration request message, the terminal and the core network cooperate to execute the terminal registration process of the 3GPP protocol, wherein the registration request message carries an indication for indicating whether the terminal is a computing power node, and the core network is used to store the indication in the registration request message in the context of the terminal. After executing the terminal registration process, the terminal is used to send a PDU session establishment request message to the core network. If the terminal is a computing power node, the PDU session establishment request message carries a request for requesting the IP address of the computing power registration center. The core network is used to return a PDU session establishment acceptance message to the terminal. The PDU session establishment acceptance message carries the IP address of the computing power registration center. After the PDU session is established, the terminal and the core network cooperate to execute the PDU session update process and establish a dedicated QoS flow for transmitting the terminal computing power information. The terminal reports and updates its computing power information to the computing power registration center through the user plane and using the application layer protocol to realize the registration and update of the terminal-side computing power information.

[0070] In this embodiment, for the terminal, the indication in the registration request message indicating whether the terminal is a computing power node is carried by the terminal capability information element. For the terminal serving as a computing power node, the PDU session establishment request message is used to request the IP address of the computing power registration center, which is carried by the protocol configuration option information element in the terminal-to-network direction. The IP address of the computing power registration center in the PDU session establishment acceptance message is returned by the protocol configuration option information element in the network-to-terminal direction.

[0071] During the base station link establishment and update phase, the base station is used to send an NG establishment request message to the core network. The NG establishment request message carries an indication of whether the base station is a computing power node. The core network is used to return an NG establishment response message to the base station. If the base station is a computing power node, the NG establishment response message carries the IP address of the computing power registration center. The base station reports and updates its computing power information to the computing power registration center through the user plane and the application layer protocol to realize the registration and update of the computing power information on the base station side.

[0072] In this embodiment, for the base station, the indication in the NG establishment request message indicating whether the base station is a computing power node is carried by the reported broadcast PLMN item information element. For the terminal serving as a computing power node, the IP address of the computing power registration center in the NG establishment response message is carried by the PLMN support item information element.

[0073] For terminals and base stations that act as computing power nodes, when the computing power nodes report and update their computing power information to the computing power registration center through the user plane and using the application layer protocol, if the HTTP / HTTPS protocol is adopted, the computing power nodes register the computing power information through the POST method and update the computing power information through the PUT method. When the base station and terminal no longer act as computing power nodes, their computing power information is deleted through the DELETE method.

Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core ideas. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as a limitation on the present invention.
