Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a high-performance connection and transmission method for wire bonding silver wire equipment. Background Art

[0002] The 3rd Generation Partnership Project (3GPP) defines a non-public network (NPN). A non-public network generally refers to a network where data does not leave the campus. Specifically, it is a dedicated network technology that can only be used by specific users or organizations to achieve security and privacy protection. A non-public network can protect the security of data transmission by using encryption technologies and security protocols to prevent data from being stolen or tampered with by unauthorized third parties. A non-public network can also provide a more reliable network connection by using dedicated network equipment and technologies to ensure the stability and accuracy of data transmission. A non-public network allows users to access restricted network resources, such as enterprise internal networks. Taking the wire bonding production scenario as an example, an operator can customize a non-public network for a wire bonding manufacturer, enabling wire bonding equipment, such as the production line of silver wire bonding equipment, to access the non-public network, thereby realizing intelligent and networked intelligent production.

[0003] However, limited by the network scale, compared with the public network, the network resources of the non-public network are relatively limited, and resource shortages may occur. In response to this situation, how to ensure the service reliability of devices in the non-public network, such as ensuring that the production stability and reliability of silver wire bonding equipment are not affected, is an urgent problem to be solved currently.

[0031] 1. The fifth-generation (5G) mobile communication system:

[0032] Figure 1 is a schematic diagram of the 5G system architecture. As Figure 1 shown, the 5G system includes: an access network (AN) and a core network (CN), and may also include: terminals.

[0033] The above-mentioned terminal can be a terminal with transceiver functions, or a chip or chip system that can be set in the terminal. This terminal can also be called a user equipment (UE), access terminal, subscriber unit, user station, mobile station (MS), mobile platform, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user equipment. The terminal in the embodiments of the present application can be a mobile phone, cellular phone, smart phone, tablet computer (Pad), wireless data card, personal digital assistant (PDA), wireless modem, handset, laptop computer, machine type communication (MTC) terminal, a computer with wireless transceiver functions, virtual reality (VR) terminal, augmented reality (AR) terminal, wireless terminal in industrial control, wireless terminal in self-driving, wireless terminal in remote medical, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, in-vehicle terminal, roadside unit (RSU) with terminal functions, etc. The terminal of the present application can also be an in-vehicle module, in-vehicle module, in-vehicle component, in-vehicle chip or in-vehicle unit built into a vehicle as one or more components or units.

[0034] The above-mentioned AN is used to implement access-related functions, can provide network access functions for authorized users in a specific area, and can determine transmission links of different qualities to transmit user data according to user levels, service requirements, etc. The AN forwards control signals and user data between the terminal and the CN. The AN may include: access network elements, which may also be referred to as radio access network (RAN) devices.

[0035] The RAN device may be a device that provides access for the terminal. For example, the RAN device may include: The RAN device may also include 5G, such as the gNB in the new radio (NR) system, or one or a group (including multiple antenna panels) of antenna panels of the base station in 5G, or may also be a network node constituting the gNB, transmission and reception point (TRP) or transmission point (TP) or transmission measurement function (TMF), such as a building base band unit (BBU), or a centralized unit (CU) or a distributed unit (DU), an RSU with base station functions, or a wired access gateway, or a core network element of 5G. Alternatively, the RAN device may also include an access point (AP) in a wireless fidelity (WiFi) system, a wireless relay node, a wireless backhaul node, various forms of macro base stations, micro base stations (also referred to as small stations), relay stations, access points, wearable devices, vehicle-mounted devices, and so on.

Or, in the next-generation mobile communication system, the network device may have other naming methods, all of which are covered by the protection scope of the embodiments of the present application, and the present application makes no limitation thereto.

[0036] The CN is mainly responsible for maintaining the subscribed data of the mobile network and providing functions such as session management, mobility management, policy management, and security authentication for the terminal. The CN mainly includes the following network elements: user plane function (UPF) network element, authentication server function (AUSF) network element, access and mobility management function (AMF) network element, session management function (SMF) network element, network slice selection function (NSSF) network element, network exposure function (NEF) network element, network function repository function (NRF) network element, policy control function (PCF) network element, unified data management (UDM) network element, application function (AF) network element, and network slice-specific and standalone non-public network (SNPN) authentication and authorization function (NSSAAF) network element.

For example, the UPF network element can receive user data from a data network (DN), and forward the user data to the terminal through an access network element. The UPF network element can also receive user data from the terminal through the access network element and forward the user data to the DN. The DN network element refers to the operator network that provides data transmission services for users. For example, Internet Protocol (IP) multimedia service (IMS), Internet, etc.

Specific functions include, for example, allocating Internet Protocol (IP) addresses for users and selecting UPFs that provide packet forwarding functions.

[0041] The PCF network element mainly supports providing a unified policy framework to control network behavior, providing policy rules to control layer network functions, and is also responsible for obtaining user subscription information related to policy decisions. The PCF network element can provide policies to the AMF network element and the SMF network element, such as quality of service (QoS) policies, slice selection policies, etc.

[0042] The NSSF network element can be used to select network slices for terminals.

[0043] The NEF network element can be used to support the opening of capabilities and events.

[0044] The UDM network element can be used to store user data, such as subscription data, authentication / authorization data, etc.

[0045] The AF network element mainly supports interacting with the CN to provide services, such as influencing data routing decisions, policy control functions, or providing some third-party services to the network side.

[0046] In the embodiments of the present invention, "indication" may include direct indication and indirect indication, and may also include explicit indication and implicit indication. If the information indicated by a certain information is called the information to be indicated, then in the specific implementation process, there are many ways to indicate the information to be indicated. For example, but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. It is also possible to indirectly indicate the information to be indicated by indicating other information, where there is an association relationship between the other information and the information to be indicated. It is also possible to only indicate a part of the information to be indicated, while the other parts of the information to be indicated are known or pre-agreed. For example, it is also possible to achieve the indication of specific information by means of the arrangement order of each information pre-agreed (such as protocol regulations), thereby reducing the indication overhead to a certain extent. At the same time, it is also possible to identify the common parts of each information and indicate them uniformly to reduce the indication overhead caused by separately indicating the same information.

[0047] In addition, the specific indication method can also be various existing indication methods, such as, but not limited to, the above-mentioned indication methods and their various combinations, etc. The specific details of various indication methods can refer to the prior art and will not be elaborated herein. As can be seen from the above description, for example, when multiple pieces of information of the same type need to be indicated, it may occur that the indication methods of different pieces of information are different.

The embodiments of the present invention do not limit the specific sending method. Among them, the sending periods and / or sending times of these sub-information can be predefined, such as predefined according to a protocol, or can be configured by the sending device by sending configuration information to the receiving device.

[0049] "Predefined" or "preconfigured" can be implemented by pre-saving corresponding codes, tables or other ways that can be used to indicate relevant information in the device. The embodiments of the present invention do not limit its specific implementation method. Among them, "saving" can mean saving in one or more memories. The one or more memories can be set separately or integrated in an encoder or decoder, a processor, or an electronic device. The one or more memories can also be partially set separately and partially integrated in a decoder, a processor, or an electronic device. The type of the memory can be any form of storage medium, and the embodiments of the present invention do not limit this.

[0050] The "protocol" involved in the embodiments of the present invention can refer to a protocol family in the communication field, a standard protocol with a frame structure similar to that of a protocol family, or a related protocol in a reliable access method system for future Internet of Things devices. The embodiments of the present invention do not make specific limitations on this.

[0051] In the embodiments of the present invention, descriptions such as "when...", "in the case of...", "if", and "when" all refer to that the device will perform corresponding processing under a certain objective situation, which does not limit the time, and does not require the device to have a judgment action when implemented, nor does it mean that there are other limitations.

[0052] In the description of the embodiments of the present invention, unless otherwise specified, " / " indicates that the objects associated before and after are in an "or" relationship. For example, A / B may represent A or B. The "and / or" in the embodiments of the present invention is merely a description of the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. Here, A and B may be singular or plural. Also, in the description of the embodiments of the present invention, unless otherwise specified, "a plurality of" means two or more than two. "At least one (item)" or its similar expression refers to any combination of these items, including any combination of a single item or plural items. For example, at least one (item) of a, b, or c may represent: a, b, c, a - b, a - c, b - c, or a - b - c, where a, b, and c may be single or multiple. Additionally, in order to clearly describe the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, terms such as "first" and "second" are used to distinguish the same items or similar items with basically the same functions and roles.

[0054] Next, the technical solutions in the present application will be described with reference to the accompanying drawings.

[0055] Please refer to Figure 2 , the embodiments of the present application provide a communication system. This communication system is applied to a private network and specifically may include: RAN devices and a bonded silver wire device cluster.

[0056] Among them, the private network may adopt the same as the above Figure 1The described network architecture also includes RAN devices and terminals, as well as some core network elements, such as AMF network elements, UDM network elements, etc. In this communication system, the specific device form of the terminal can be a bonded silver wire device, such as a bonded silver wire device cluster composed of multiple bonded silver wire devices. Among these multiple bonded silver wire devices, some bonded silver wire devices are provided with at least two antenna panels to support multi-beam simultaneous transmission in the uplink or downlink, that is, at least two antenna panels each transmit an uplink or downlink beam, so as to improve data transmission efficiency and reduce latency. Another part of these multiple bonded silver wire devices is provided with a single antenna panel. The bonded silver wire device cluster is deployed in a private network. Usually, the bonded silver wire device cluster also accesses the private network, such as accessing the RAN device, and registers to the core network of the private network through the RAN device. After that, a service process is established, such as establishing a protocol data unit (PDU) session.

[0057] Next, the interaction between the management device and the operator network in the above production system will be described in detail in combination with the method.

[0058] Please refer to Figure 3 , the embodiment of the present application provides a high-performance connection and transmission method for bonded silver wire devices. This method can be applied to the communication between RAN devices and bonded silver wire device clusters. The process of this method includes:

[0059] S301, the RAN device determines that there are N bonded silver wire devices in the bonded silver wire device cluster that need to switch networks.

[0060] Among them, the bonded silver wire device cluster is a cluster of terminal devices deployed in NPN and subscribed to NPN. The bonded silver wire device cluster currently accesses NPN, and N is an integer greater than 1.

[0061] The RAN device can determine that it cannot allocate resources that meet the requirements of the bonded silver wire device cluster to the bonded silver wire device cluster according to the resource usage situation of the RAN device.

[0062] For example, first, the RAN device can estimate the resources that the RAN device will allocate to each terminal currently accessing the RAN device according to the number of terminals currently accessing the RAN device and the service priority of each terminal currently accessing the RAN device.

[0063] Among them, the terminals currently accessing the RAN device include a bonded silver wire device cluster. The RAN device can determine the number of terminals currently accessing the RAN device at a preset judgment time in the current cycle. Or; the RAN device can also determine the number of terminals currently accessing the RAN device when the number of terminals accessing the RAN device changes. Or; the RAN device can also receive a service request from the AF through the AMF network element serving the NPN. Among them, the AF is used to provide control services for the bonded silver wire device cluster, and the service request is used to request the RAN device to evaluate the service quality of the RAN device serving the bonded silver wire device cluster. Thus, in response to the request for the RAN device to evaluate the service quality of the RAN device serving the bonded silver wire device cluster, the RAN device determines the number of terminals currently accessing the RAN device. If the service priority of each terminal currently accessing the RAN device is higher, the more resources the RAN device is expected to allocate to this terminal. The resources allocated by the RAN device to each terminal currently accessing the RAN device are the resource usage of the RAN device.

[0064] Exemplarily, taking the bonded silver wire device cluster including 4 bonded silver wire devices as an example, if the service priority of bonded silver wire device #1 is level 1, the resources that the RAN device is expected to allocate to this bonded silver wire device #1 are 20MB of bandwidth. If the service priority of bonded silver wire device #2 is level 2, which is lower than level 1, the resources that the RAN device is expected to allocate to this bonded silver wire device #2 are 15MB of bandwidth. If the service priority of bonded silver wire device #3 is level 3, which is lower than level 2, the resources that the RAN device is expected to allocate to this bonded silver wire device #3 are 10MB of bandwidth. If the service priority of bonded silver wire device #4 is also level 3, the resources that the RAN device is expected to allocate to this bonded silver wire device #4 are also 10MB of bandwidth.

[0065] After that, the RAN device can determine the resources that the RAN device will allocate to the bonded silver wire device cluster according to the resources that the RAN device will allocate to each terminal currently accessing the RAN device. Continuing with the above example, for the above 4 bonded silver wire devices, the resources that the RAN device will allocate to the bonded silver wire device cluster are 20MB + 15MB + 10MB + 10MB = 55MB of bandwidth. The RAN device determines that the resources that the RAN device will allocate to the bonded silver wire device cluster are less than the resources required by the bonded silver wire device cluster. Among them, the resources required by the bonded silver wire device cluster are stored in the context of the bonded silver wire device cluster on the local RAN device; the fact that the resources that the RAN device will allocate to the bonded silver wire device cluster are less than the resources required by the bonded silver wire device cluster means that the RAN device cannot allocate resources that meet the requirements of the bonded silver wire device cluster to the bonded silver wire device cluster. Continuing with the above example, the resources required by the bonded silver wire device cluster are 80M of bandwidth, that is, 20M of bandwidth for each bonded silver wire device. Then, the above 55MB of bandwidth is less than 80M of bandwidth, indicating that the RAN device cannot allocate resources that meet the requirements of the bonded silver wire device cluster to the bonded silver wire device cluster.

[0066] In the case where the RAN device cannot allocate resources that meet the requirements of the bonded silver wire device cluster to the bonded silver wire device cluster, the RAN device can determine that the number of bonded silver wire devices that need to switch networks in the bonded silver wire device cluster is N according to the difference between the resources that the RAN device will allocate to the bonded silver wire device cluster and the resources required by the bonded silver wire device cluster. Continuing with the above example, 80MB - 55MB = 25MB, and each bonded silver wire device is 20M of bandwidth. At this time, N = 2, that is, 2 bonded silver wire devices need to be switched to access the public network, so that the remaining bonded silver wire devices can be allocated resources that meet their own requirements. The RAN device selects a target bonded silver wire device and N - 1 other bonded silver wire devices from the N bonded silver wire devices according to the number of bonded silver wire devices that need to switch networks in the bonded silver wire device cluster being N. Among them, the target bonded silver wire device is the bonded silver wire device with the worst signal quality between the RAN device among the bonded silver wire devices with at least two antenna panels. The target bonded silver wire device can perform uplink or downlink multi-beam simultaneous transmission through at least two antenna panels of the target bonded silver wire device, so as to ensure that the communication rate is large enough to support N bonded silver wire devices to obtain services from the first PLMN. The N - 1 other bonded silver wire devices are the bonded silver wire devices with the first N - 1 worst signal qualities between the RAN device among the bonded silver wire devices with one antenna panel.

[0067] Optionally, Method 1: In the case where the RAN device cannot allocate resources that meet the requirements of the bonded silver wire device cluster for the bonded silver wire device cluster, and before selecting N bonded silver wire devices, the RAN device may also send a subscription request to the AMF network element serving the NPN. Among them, the subscription request is used to request to subscribe to the network capability information in the group subscription data of the bonded silver wire device cluster. The RAN device receives the subscription acceptance returned by the AMF network element for the subscription request. Among them, the subscription acceptance carries network capability information, and the network capability information is used to indicate that the bonded silver wire device cluster supports switching from the NPN to the public network. The RAN device determines that the bonded silver wire device cluster has the ability to switch from the NPN to the public network according to the network capability information.

[0068] Optionally, Method 2: In the case where the bonded silver wire device cluster has the ability to switch from the NPN to the public network, and before selecting N bonded silver wire devices, the RAN device may also trigger a configuration update (SOR) process to obtain a network list that the bonded silver wire device cluster can switch to from the UDM network element serving the NPN. The network list includes at least one PLMN, such as the identifiers of at least one PLMN. Among them, the first PLMN is the PLMN with the highest priority among the at least one PLMN.

[0069] It can be understood that the RAN device can also directly obtain the network list from the AMF network element through Method 1. For Method 2, since the SOR process is usually initiated by the terminal, the difference in this application is that the RAN device acts as an agent for the terminal to initiate the SOR process to obtain the network list from the UDM network element.

[0070] S302. The RAN device sends indication information to N bonded silver wire devices.

[0071] Among them, the indication information is used to indicate that the target bonded silver wire device among the N bonded silver wire devices needs to switch from the NPN to access the first Public Land Mobile Network (PLMN), and the indication information is also used to indicate that the other bonded silver wire devices among the N bonded silver wire devices except the target bonded silver wire device need to establish a PC5 connection with the target bonded silver wire device. The first PLMN is the public network. For example, the RAN device may send the first indication information to the target bonded silver wire device among the N bonded silver wire devices. The first indication information indicates that the target bonded silver wire device needs to switch from the NPN to access the first PLMN by carrying the identifier of the first PLMN. Among them, the first PLMN has previously saved the subscription data of the target bonded silver wire device in the first PLMN to support the target bonded silver wire device to be able to switch from the NPN to access the first PLMN. The RAN device may also send the second indication information to each of the N - 1 other bonded silver wire devices among the N bonded silver wire devices. The second indication information indicates that the N - 1 other bonded silver wire devices need to establish a PC5 connection with the target bonded silver wire device by carrying the identifier of the target bonded silver wire device.

[0072] In summary:

[0073] In a private network, when the resources of RAN devices in the private network are in short supply, the RAN device can switch some of the bonded silver wire devices in the bonded silver wire device cluster currently deployed and connected to the private network, such as N bonded silver wire devices, to connect to the public network, such as the first PLMN, so as to continue to guarantee the services of these N bonded silver wire devices through the resources of the first PLMN, thereby realizing that the production stability and reliability of the bonded silver wire devices can be ensured without being affected in the case of network resource shortage. Moreover, since only one target bonded silver wire device among these N bonded silver wire devices is connected to the first PLMN, and the remaining bonded silver wire devices obtain services from the first PLMN by establishing a PC5 connection with the target bonded silver wire device, the air interface resource overhead of the first PLMN can also be reduced, and too much impact on the original services in the first PLMN can be avoided.
