These key capability indicators represent at least an order of magnitude improvement over their 5G counterparts, and also introduce more new capability indicators across various dimensions.

[0040] The following describes the technical terms relevant to this application.

[0041] 1) Digital Twin

[0042] Digital twins fully utilize data from physical models, sensor updates, and operational history to integrate multi-disciplinary, multi-physical, multi-scale, and multi-probabilistic simulation processes, mapping these data in a virtual space to reflect the entire lifecycle of the corresponding physical equipment. Initially proposed for digitizing fighter jet maintenance, they have since found applications in industrial manufacturing and smart cities. With the emergence of new mobile network services and the continuous expansion of network scale, network operation and maintenance have become increasingly complex, making the deployment of innovative technologies difficult. Therefore, digital twins are considered a crucial direction for 6G networks, providing intelligent operation and maintenance and smart autonomy throughout the entire lifecycle of mobile networks.

[0043] 2) Complexity and power consumption

[0044] Looking at the development history from 2G, 3G, 4G to 5G, the continuous expansion of network scale and the increasing complexity have led to complex and redundant network architectures. Based on existing network development trends, the complexity of 6G networks supporting the Internet of Things will increase exponentially. Currently, the industry generally assesses that the computational complexity of 5G will be 10 to 20 times higher than that of 4G modems. Continuing in this direction, the complexity of 6G will be at least an order of magnitude higher than that of 5G. Therefore, 6G terminals will inevitably adopt low-complexity design schemes.

[0045] Mobile phone battery capacities are constantly increasing, with 4500mAh being a common capacity now. However, battery life is the same as, or even shorter than, that of 4G phones. According to test data from relevant organizations, due to factors such as the increased number of transmitting and receiving antennas, the increased complexity of baseband processing, and the coverage of 5G network deployment, the power consumption of 5G phones is currently about 20% higher than that of 4G phones.

[0046] The following describes several scenarios involved in this application.

[0047] When digital twin networks involve terminals, the protocol functions of the terminals need to be customized for modem-related digital twin services. Existing terminals are difficult to support UE modem-related digital twin services, therefore, it is necessary to solve the digital twin problem at the UE modem level.

[0048] For example, an operator develops its own enterprise standards based on 3GPP Rx (e.g., R16) standards. Network equipment and mobile terminals in this operator's commercial network all adhere to these enterprise standards. Based on this commercial network, the operator provides digital twin network services to itself, internet app developers, equipment manufacturers, and terminal manufacturers. When digital twin network services provide digital twin domain verification for potentially commercial new technologies, it is usually necessary to incrementally add new functionalities to the existing enterprise standard functions. These newly added functionalities may be standard-defined functions or lightweight, custom (non-standard) small functions based on standard-defined functions. Specific examples are shown below.

[0049] When operators provide digital twin networks as a new service to terminal manufacturers, equipment vendors, etc., the specific scenarios include at least the following: terminal companies solve and verify modem functions, equipment vendors provide new functions based on a certain version of the protocol, and operators launch new functions according to business needs.

[0050] Scenario 1: A network operator's network operation and maintenance optimization department is conducting network optimization research and development, which requires the use of newly defined functions in Ry (e.g., R17) (such as enhanced positioning). During this new technology development process, the performance of the solution needs to be verified and iteratively optimized. Alternatively, equipment vendors may also need to use newly defined functions in Ry (e.g., R17) during the development of new network technologies (such as some functions of NR-light in industrial scenarios). Therefore, for the mobile terminals conforming to enterprise standards based on Rx (e.g., R16) as described in the example, the above function updates cannot be achieved through existing signaling or network management configurations. When using the operator's digital twin service for end-to-end new technology verification during the above new technology development, the protocol software functions on the digital twin UE side need to be updated. A potential time-division multiplexing digital twin solution is based on user authorization, sending the protocol software functions of the digital twin user to the user via the air interface during the early morning hours for installation and use. After the digital twin is completed, the protocol software used by the UE in the commercial network is restored. With UE-side hardware support, the above-mentioned protocol software that needs to be installed and used by the UE may come from operators, equipment vendors, etc., and is not limited to chip manufacturers or terminal manufacturers. Furthermore, the verification of the aforementioned new technologies typically requires equivalent support from network-side devices and even application-layer functions. Therefore, the update process requires unified control of the process by the network side, sending and instructing the UE side to complete the protocol software update.

[0051] Scenario 2: When adding new features (such as newly defined NAS messages) or optimizing communication performance in a terminal company's modem, network equipment is required for verification during the R&D process. Building a verification environment in-house often involves significant manpower and high equipment costs, and it's difficult to achieve interoperability verification across all equipment providers in the operator's network, and it's also difficult to cover different network coverage and topology scenarios in commercial networks. The aforementioned digital twin service can support the terminal company's new technology verification, but it requires hardware support on the UE side and user authorization, and involves downloading and installing protocol software functions to create a digital twin UE. Therefore, the network side needs to uniformly control the above process, sending and instructing the UE side to complete protocol software updates and configuring the digital twin UE. The aforementioned online upgrade of terminal-side protocol functions is also essential for industry terminals in industry network scenarios. Due to the limitations of deployment and installation in industry environments, industry terminals typically have longer usage cycles than ordinary user terminals, thus requiring online upgrades of the terminal-side protocol software for new functions during use.

[0052] Scenario 3: The new functions used in Scenario 1 above may also be potential Rz (such as R18) technologies, which are currently non-standardized functions. Alternatively, they may be lightweight functions customized by operators or equipment vendors based on the aforementioned (R16) enterprise standard. Therefore, these functions cannot be implemented through existing signaling or network management configurations. Similar to Scenario 1, UE-side software function updates are required for verification. Further targeting 6G networks, a potential solution is based on standard-defined physical layer (or part of MAC) technology. (Part of) MAC and above functions support different service requirements through air interface protocol software download and updates. Under this technical solution, the network and terminal need to interact to download and update protocol software.

[0190] The following example illustrates the method for updating the terminal protocol function of this application, using specific application scenarios as examples.

[0191] Embodiment 1 of the present invention: A method for updating terminal protocol functions based on MAC CE

[0192] The methods for updating the terminal protocol functionality include:

[0193] Step 1: The base station sends a protocol function software update request for the first service (i.e., the second protocol function update request described in the above embodiment) to the terminal through the MAC CE. The protocol function software update request includes at least one of the following: the configured protocol function range, which includes at least one of the following: physical layer protocol function, higher layer user plane protocol function, higher layer control plane protocol function, NAS protocol function, and application layer protocol function.

[0194] Optionally, the MAC CE may also include: the service type of the requested protocol function software and the requested updated protocol function software (i.e., the protocol function software configuration information of the first service).

[0195] That is, in this embodiment of the application, the protocol function software update request and the protocol function software configuration information can be sent in the same message. Of course, they can also be sent separately; for example, the protocol function software update request can be sent via MAC CE, and the protocol function software can be sent via the user plane. That is, the protocol function software can be sent via either MAC CE or the user plane.

[0196] In this embodiment of the application, a new protocol software update MAC CE can be added, which is included in the extended definition of the extended logical channel identifier (eLCID).

[0197] In this embodiment of the application, the protocol function configuration information may optionally be one of the following:

[0198] 1) Complete protocol function documentation;

[0199] Optionally, the complete protocol function file includes: a protocol function description and a protocol function file, wherein the protocol function description includes at least one of the following: a protocol function indicator, a protocol interface indicator, an updated protocol function file length indicator, and a protocol function identifier.

[0200] A complete protocol function file is, for example, a complete UE-side baseband processing function software. Figure 4 As shown, Figure 4 This is a schematic diagram illustrating the protocol function description of the UE-side baseband processing function software according to an embodiment of this application. When Protocol SWFunction Indication is all 1s, it represents complete UE-side baseband processing function software; when Protocol SWInterface Indication is 001, it represents the NGAP interface. When Length Of Protocol SW File is 0000 11111111 1111, it indicates that the protocol function file length is 4095 bytes. The protocol function identifier is used to identify the protocol function, and the subsequent fields represent the protocol function file.

[0201] 2) Some protocol function files;

[0202] Optionally, the partial protocol function file includes: a protocol function description and a protocol function file. The protocol function description includes at least one of the following: a reference template or reference function for the protocol function, a protocol function indication, a protocol interface indication, an updated protocol function file length indication, and a protocol function identifier.

[0203] The term "partial protocol function file" refers to a file that does not need to include protocol function configuration information for each layer, but can update only the protocol function configuration information for a portion of the layers, such as the PDCP layer.

[0204] Some protocol function files, such as those updating to add a new header compression function defined by PDCP, may contain protocol function descriptions and software files. The protocol function descriptions may include a reference template / function (e.g., R16-PDCP), protocol function indicators, protocol interface indicators, protocol software length indicators, and / or protocol function identifiers.

[0205] 3) Incremental protocol function files based on historical downloads.

[0206] Optionally, the incremental protocol function file based on historical downloads includes: a protocol function description and a protocol function file. The protocol function description includes at least one of the following: a reference template or reference function for the protocol function (e.g., a protocol software function identified as ×× in historical downloads), the insertion position information of the incremental protocol function (e.g., the position of the 1000th byte), an indication of the length of the updated protocol function file, and a protocol function identifier.

[0207] The aforementioned protocol function identifiers can also serve as reference templates or reference functions for protocol functions, thereby enabling incremental updates based on the versions represented by the aforementioned identifiers.

[0208] Step 1 above can be completed by one or more messages. One feasible approach is for the base station to send only the protocol function description via the MAC CE, such as the aforementioned protocol function indication, protocol interface indication, updated protocol function file length indication, and / or protocol function identifier. The protocol function file is then sent via the user plane. In this case, a dedicated logical channel needs to be defined so that the UE can identify it from the MAC PDU and install and update it. This approach is more suitable for downloading large protocol function software.

[0209] Step 2: The terminal updates the protocol function software according to the above protocol function configuration information.

[0210] If the protocol function software update is completed, the UE sends an update completion message to the base station. If the update is complete and the UE only supports the updated protocol function software, the UE deletes the old protocol function software. If the update is successful and the UE can support multiple protocol function software, the network side can send the usage rule configuration for the successfully updated protocol function to the UE through RRCreconfiguration.

[0211] If the protocol function software update fails, the terminal sends an update failure message to the network-side device and deletes the updated protocol function software.

[0212] Embodiment 2 of the present invention: A method for updating terminal protocol functions based on RRC messages

[0213] Please refer to Figure 5 The methods for updating the terminal protocol function include:

[0214] Step 1: The network device sends a protocol software update request for the first service (i.e., the second protocol function update request mentioned in the above embodiment) to the terminal via RRC signaling. The protocol software update request includes at least one of the following: the configured protocol function range, which includes at least one of the following: physical layer protocol functions, higher layer user plane protocol functions, higher layer control plane protocol functions, NAS protocol functions, and application layer protocol functions.

[0215] Optionally, the MAC CE may also include: the service type of the requested protocol function software and the requested updated protocol function software (i.e., the protocol function software configuration information of the first service).

[0216] The content of the protocol function configuration information is described in Example 1 and will not be repeated here.

[0217] Step 1 above can be completed by one or more messages. One feasible approach is for the base station to send only the protocol function description via RRC signaling, such as the aforementioned protocol function indication, protocol interface indication, updated protocol function file length indication, and / or protocol function identifier. The protocol function file is then sent via DRB. In this case, the PDCP PDU header needs to indicate that the user plane data packet is a protocol function software file so that the UE can identify it from the PDCP PDU and install and update it. This approach is more suitable for downloading large protocol function software.

[0218] Step 2: The terminal updates the protocol function software according to the above protocol function configuration information.

[0219] 2a: If the protocol function software update is completed, the UE sends an RRC update complete message to the base station. If the update is complete and the UE only supports the updated protocol function software, the UE deletes the old protocol function software. If the update is successful and the UE can support multiple protocol function software, the network side can send the usage rule configuration for the successfully updated protocol function to the UE through RRCreconfiguration.

[0220] 2b: If the protocol function software update fails, the terminal sends an update failure message "protocol software update failure" to the network-side device and deletes the updated protocol function software.

[0221] Embodiment 3 of the present invention: Terminal protocol function software update scheme triggered by terminal based on NAS messages

[0222] Please refer to Figure 6 The methods for updating the terminal protocol function include:

[0223] Step 1: The UE sends a protocol function software update request for the first service, NAS MM Transport (protocol software update), which is the first protocol function update request described in the above embodiment. The protocol function software update request includes at least one of the following: the configured protocol function range, which includes at least one of the following: physical layer protocol function, higher layer user plane protocol function, higher layer control plane protocol function, NAS protocol function, and application layer protocol function.

[0224] In this embodiment of the application, the configured protocol function range can be defined as a protocol type information unit, and a potential implementation scheme is to use 5 bits to represent it (which can support 31 potential protocol function cases).

[0225] Optionally, a protocol function software update request may also include: the service type of the requested protocol function software and suggestions or requirements for the requested update of the protocol function software.

[0226] Step 2: If the AMF supports protocol function software updates, then the AMF analyzes whether there is available protocol function software based on the request message and / or UE context information and / or UE subscription information, etc.

[0227] Step 2a: If available protocol software is available, the AMF sends a protocol software function update acceptance message to the UE. For the transmission method of the protocol function software, one method is through NAS information delivery. In this case, it's important to note that NAS messages have a maximum length limit (e.g., NR is 9000 bytes). If the protocol software exceeds the maximum length of the NAS message, segmentation and reassembly are required. The other method is through the user plane, which requires providing a service identifier (e.g., similar to the IMS definition of protocol software update service) so that the UE's baseband processing unit can identify and use it. The protocol function software update process is the same as in Example 1.

[0228] Step 2b: If no possible protocol software is available, send a protocol software function update rejection message to the UE.

[0229] Step 3: If the protocol function update is supported by other network functions in the core network, as shown in the diagram using xNF as an example, then AMF needs to support the transparent transmission of this message. xNF analyzes whether there is available protocol function software based on the request message and / or UE context information and / or UE subscription information.

[0230] Step 4.1a: If xNF has available protocol function software, follow the same process as step 2a;

[0231] Step 4.1b: If not, xNF sends a Protocol Software Function Update Rejection Message to the UE.

[0232] Step 5: Optional, the UE reports the protocol software update status.

[0233] Step 6a: Optionally, if the update is successful and the UE can only support the requested protocol function, the network side sends an old protocol function software deletion message to the UE. Only after receiving this message can the UE delete the old protocol software.

[0234] Step 6b: Optionally, if the update is successful and the UE supports both the updated protocol functions and the old protocol function software, the network side sends the operation rules of the successfully updated protocol function software to the UE, such as which eSIM it belongs to.

[0235] Step 7: Optionally, if the update fails, the network side sends a recovery message to the UE, and the UE deletes the received protocol function software and continues to use the old protocol function software before the update.

[0236] Please refer to Figure 7 In this embodiment of the application, optionally, the above-mentioned protocol function update request, acceptance and rejection messages can be added to the 5GSmobility management message.

[0237] Embodiment 4 of the present invention: A network-triggered terminal protocol function software update scheme based on NAS messages.

[0238] Please refer to Figure 8 The methods for updating the terminal protocol function include:

[0239] Step 1: The network-side device sends a protocol software update request (NAS MM transport) for the first service, which is the second protocol software update request described in the above embodiment. The protocol software update request includes at least one of the following: the configured protocol function range, which includes at least one of the following: physical layer protocol functions, higher layer user plane protocol functions, higher layer control plane protocol functions, NAS protocol functions, and application layer protocol functions.

[0240] In this embodiment of the application, the configured protocol function range can be defined as a protocol type information unit, and a potential implementation scheme is to use 5 bits to represent it (which can support 31 potential protocol function cases).

[0241] Optionally, a protocol function software update request may also include: the service type of the requested protocol function software and suggestions or requirements for the requested update of the protocol function software.

[0242] Steps 2.1a-2.2a: If the UE analyzes its hardware and resources and finds that it can support the protocol function software update, then the UE sends a receive message to the network. The method of transmitting the protocol software is the same as step 2a in Embodiment 3.

[0243] Step 2b: If the UE does not support the protocol function software update, then the UE sends a rejection message to the network.

[0244] It should be noted that the terminal protocol function update method provided in this application embodiment can be executed by a terminal protocol function update device, or by a control module in the terminal protocol function update device for executing the terminal protocol function update method. This application embodiment uses the execution of the terminal protocol function update method by a terminal protocol function update device as an example to illustrate the terminal protocol function update device provided in this application embodiment.
