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 composed of an open computing network infrastructure based on the 5G-A / 6G network architecture and computing resources. It introduces unified scheduling of networks and computing power, and can make full use of computing power resources such as terminal computing power, base station computing power, and edge computing power. With the help of computing power scheduling, the experience of 5G access services can be improved, the computing network experience of end-to-end services can be optimized, and the utilization rate of mobile computing network resources can be improved to achieve the coordination of mobile networks and computing power. In addition, mobile networks naturally support the mobility of terminal users, and provide efficient scheduling and QoS guarantee 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 connection capabilities for computing network coordination 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, to provide a reference for the subsequent unified orchestration of computing network resources.

[0004] Existing computing power perception solutions (including computing power registration and computing power update) are mainly aimed at bearer networks. Bearer networks and mobile communication networks have many differences in architecture, interface and communication protocol, and related solutions cannot be directly applied to mobile communication networks. For mobile computing power networks, one current implementation solution is to add a computing power registration center to the core network, and expand the control plane N1 (NAS) and N2 (NGAP) interfaces. That is, the UE uses the registration N1 message to report the terminal's computing power information to the computing power registration center, and the base station uses NG to establish the N2 message for reporting. This solution requires major changes to the 3GPP standard interface, which is difficult to standardize and promote on a large scale.

[0005] How to achieve computing power perception in mobile computing 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, and 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 acceptance message to the terminal, and 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 and using the application layer protocol to realize the registration and update of the computing power information on the terminal side;

[0009] Base station link establishment 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 using 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 through the terminal capability information element. For the terminal that is 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 through 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 through the protocol configuration option information element in the network-to-terminal direction.

[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 stations and terminals no longer serve as computing power nodes, their computing power information is deleted through the DELETE method.

[0014] In 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 cooperates with the core network to execute the PDU session update process, establish a dedicated QoS flow for transmitting terminal computing power information, and 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 computing power information on the terminal side.

[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 using 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 through the terminal capability information element. For the terminal that is 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 through 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 through 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 through the reported broadcast PLMN item information element, and for the base station that serves as a computing power node, the IP address of the computing power registration center in the NG establishment response message is carried through the PLMN support item information element.

[0024] The present invention is further described below in conjunction with 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 are not intended to limit the present invention. In the absence of 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] Embodiment 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, wherein an N6 interface exists between a user plane of the core network 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, and 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 the computing power information on the terminal side.

[0029] 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. 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 through 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 through the protocol configuration option (PCO) information element in the network-to-terminal direction.

[0030] Base station link establishment 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 using 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 used to indicate 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, and 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 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 the terminal no longer act 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 (RegisterRequest) NAS message to 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, perform the UE initial registration process, and 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 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 the IE contains a dedicated parameter container. In this embodiment, in the terminal-to-network direction, a container identifier value reserved by the protocol 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 PDUSessionEstablishmentRequest message in the N1 SMcontainer and the UE's computing node indication;

[0042] Step 5: SMF interacts with UDM to obtain the 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 to execute the PDU session establishment process;

[0046] Step 8: AMF returns a PDU session establishment accept (PDUSessionEstablishmentAccept) message to the UE, corresponding to the PCO / ePCO request parameter in the PDU session establishment request message, and 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, execute the PDU session update process, and 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 belongs to high-priority signaling, preferably, the QoS flow is of non-GBR type and uses the same 5QI value as the IMS signaling (5QI=5).

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

[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: The terminal meets the computing power information update conditions, such as computing resources decreasing by a preset percentage, and 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 the terminal no longer serves as a computing power node (for example, the remaining power is insufficient), the HTTP / HTTPSDELETE method can be used to notify the computing power registration center to delete its computing power information, and then no longer participate in computing power scheduling, and re-register for computing power after the 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 response to NG-RAN. For computing power 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: The base station meets the computing power information update conditions, such as computing resources decreasing by a preset percentage, and 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 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, and 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. In this embodiment, the computing power information transmitted between NG-RAN and UPF is not related to the UE, and the existing protocol process needs to be adaptively modified for the transmission of non-UE-related data. The modified process can be used in a variety of scenarios, not only for the computing power information transmission of this embodiment, but also for the perception data transmission between NG-RAN and SF (perception function) via UPF in the interaesthesia fusion scenario. The specific modification method is not described in the present invention.

[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, and 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, establish a dedicated QoS flow for transmitting terminal computing power information, and 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 computing power information on the terminal side.

For the terminal 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 through 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.

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 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.
