Technical Field

The application relates to the technical field of communication, in particular to a high-performance connection and transmission method of bonding silver wire equipment.

Background

The third generation partnership project (3rd Generation Partnership Project,3GPP) defines a private network (NPN). Private networks generally refer to networks where data does not go out of the campus, and in particular, a private network technology can only be used by a specific user or organization to achieve security and privacy protection. The private network can protect data transmission from theft or tampering by unauthorized third parties by using encryption techniques and security protocols. The private network can also provide a more reliable network connection by using dedicated network devices and technologies to ensure the stability and accuracy of data transmission. The private network may allow users to access restricted network resources, such as an enterprise intranet, and the like. Taking the bonding wire production scene as an example, an operator can customize a private network for a bonding wire manufacturer, so that bonding wire equipment, such as a production line of bonding silver wire equipment, can be connected into the private network, thereby realizing intelligent and networked intelligent production.

However, the private network is limited by the network scale, and compared with the public network, the network resources are limited, and the situation of resource shortage may occur, and for this situation, how to ensure the service reliability of the devices in the private network, such as ensuring that the production stability and reliability of the bonded silver wire devices are not affected, is a problem to be solved at present.

The technical solutions in the present application will be described below with reference to the accompanying drawings.

Referring to fig. 2, an embodiment of the present application provides a communication system, where the communication system is applied to a private network, and may specifically include: RAN device and bonded silver wire device cluster.

The private network may adopt a network architecture similar to that described in fig. 1, and also includes RAN devices and terminals, and some core network elements, such as AMF network elements, UDM network elements, and so on. In the communication system, the terminal specific device form may be a bonded silver wire device, such as a bonded silver wire device cluster formed by a plurality of bonded silver wire devices. Some of the plurality of bonding silver wire devices are provided with at least two antenna panels for supporting uplink or downlink multi-beam simultaneous transmission, that is, the at least two antenna panels respectively transmit uplink or downlink beams, thereby improving data transmission efficiency and reducing time delay. Another portion of the plurality of bonded silver wire devices is provided with a single antenna panel. The cluster of bonded silver devices is deployed into the private network, and in a normal case, the cluster of bonded silver devices is also connected into the private network, such as a RAN device, and registered to a core network of the private network through the RAN device, and then a service flow, such as a Protocol Data Unit (PDU) session, is established.

The interaction of the management device and the operator network in the above-described production system will be described in detail below in connection with the method.

Referring to fig. 3, an embodiment of the present application provides a high performance connection and transmission method for a bonded silver wire device. The method may be applicable to communications between RAN devices and clusters of bonded silver wire devices. The method comprises the following steps:

s301, the RAN device determines that N bonding silver wire devices in the bonding silver wire device cluster need to switch networks.

The bonding silver wire equipment cluster is a cluster of terminal equipment which is deployed on the NPN and signed with the NPN, the bonding silver wire equipment cluster is currently connected to the NPN, and N is an integer larger than 1.

The RAN equipment can determine that resources meeting the demands of the bonding silver wire equipment clusters cannot be allocated to the bonding silver wire equipment clusters according to the resource use condition of the RAN equipment.

For example, first, the RAN device may estimate resources to be allocated by the RAN device for each terminal currently accessing the RAN device according to the number of terminals currently accessing the RAN device and the traffic priority of each terminal currently accessing the RAN device.

The terminal accessed to the RAN equipment currently comprises a bonding silver wire equipment cluster. The RAN device may determine the number of terminals currently accessing the RAN device at a preset determination opportunity of the current period. Or alternatively; the RAN equipment can also determine the number of terminals accessing the RAN equipment currently or when the number of terminals accessing the RAN equipment is changed; the RAN device may also receive a service request from the AF through an AMF network element serving the NPN. The AF is used for providing control service for the bonding silver wire device cluster, and the service request is used for requesting the RAN device to evaluate the service quality of the RAN device service bonding silver wire device cluster. As such, in response to requesting the RAN device to evaluate a quality of service of the RAN device service bonded silver wire device cluster, the RAN device determines a number of terminals currently accessing the RAN device. If the service priority of each terminal currently accessing the RAN equipment is higher, the estimated RAN equipment allocates more resources for the terminal. The resources allocated by the RAN equipment to each terminal accessed to the RAN equipment at present are the resource use condition of the RAN equipment.

Taking an example that the bonded silver wire device cluster includes 4 bonded silver wire devices, if the service priority of the bonded silver wire device #1 is level 1, the estimated RAN device will allocate a bandwidth of 20MB to the bonded silver wire device # 1. If the service priority of the bonding silver wire device #2 is 2 and is lower than the service priority of the bonding silver wire device #2 by 1, the estimated resources to be allocated to the bonding silver wire device #2 by the RAN device are 15MB of bandwidth. If the service priority of the bonding silver wire device #3 is 3 and is lower than the service priority of the bonding silver wire device #3 by 2, the estimated resources to be allocated to the bonding silver wire device #3 by the RAN device are 10MB of bandwidth. If the traffic priority of the bonding wire device #4 is also level 3, the estimated resources to be allocated by the RAN device to the bonding wire device #4 are also 10MB of bandwidth.

The RAN device may then determine the resources to be allocated by the RAN device for the cluster of bonded silver wire devices based on the resources to be allocated by the RAN device for each terminal currently accessing the RAN device. Continuing with the example above, for the 4 bonded silver devices described above, the RAN device will allocate 20mb+15 mb+10mb+10mb=55 MB of bandwidth for the cluster of bonded silver devices. The RAN device determines that the RAN device is to allocate less resources for the cluster of bonded silver devices than are required by the cluster of bonded silver devices. The resources required by the bonding silver wire equipment cluster are stored in the context of the bonding silver wire equipment cluster local to the RAN equipment; the RAN device will allocate less resources to the cluster of bonded silver devices than the resource representation required by the cluster of bonded silver devices: the RAN device cannot allocate resources for the cluster of bonded silver devices that meet the requirements of the cluster of bonded silver devices. Continuing with the above example, if the bandwidth of the resource 80M required by the bonded silver device cluster, i.e. the bandwidth of each bonded silver device is 20M, the bandwidth of 55MB is smaller than the bandwidth of 80M, which indicates that the RAN device cannot allocate the resource meeting the requirement of the bonded silver device cluster for the bonded silver device cluster.

Under the condition that the bonding silver wire equipment cluster cannot be allocated with the resources meeting the requirements of the bonding silver wire equipment cluster, the RAN equipment can determine that the number of bonding silver wire equipment needing to switch networks in the bonding silver wire equipment cluster is N according to the difference value between the resources to be allocated for the bonding silver wire equipment cluster by the RAN equipment and the resources required by the bonding silver wire equipment cluster. Continuing with the above example, 80MB-55 mb=25mb, and each bonding wire device has a bandwidth of 20M, where n=2, i.e. 2 bonding wire devices need to be switched to access the public network, then the remaining bonding wire devices can be allocated resources that meet their own needs. The RAN equipment selects a target bonding silver wire device and N-1 other bonding silver wire devices from the N bonding silver wire devices according to the number of the bonding silver wire devices needing to switch networks in the bonding silver wire device cluster. The target bonding silver wire device is bonding silver wire device with the worst signal quality between the bonding silver wire device and the RAN device, and the target bonding silver wire device can execute uplink or downlink multi-beam simultaneous transmission through the at least two antenna panels of the target bonding silver wire device, so that the communication rate can be ensured to be large enough, and N bonding silver wire devices can be supported to acquire service from the first PLMN. N-1 other bonded silver wire devices are provided with bonded silver wire devices of an antenna panel having a signal quality front N-1 difference with the RAN device.

Alternatively, mode 1: in the case that the RAN device cannot allocate resources meeting the requirements of the bonded silver device cluster to the bonded silver device cluster, and before selecting N bonded silver devices, the RAN device may further send a subscription request to an AMF network element serving the NPN. The subscription request is used for requesting to subscribe to network capability information in group subscription data of the bonded silver wire device cluster. The RAN equipment receives subscription acceptance returned by the AMF network element for the subscription request. The subscription acceptance carries network capability information, and the network capability information is used for indicating that the bonded silver wire equipment cluster supports switching from NPN to public network. And the RAN equipment determines that the bonding silver wire equipment cluster has the capability of switching from NPN to public network according to the network capability information.

Alternatively, mode 2: in the case that the bonded silver device cluster has the capability of switching from NPN to public network, and before selecting N bonded silver devices, the RAN device may further trigger a configuration update (SOR) procedure, obtain, from a UDM network element serving NPN, a network list that the bonded silver device cluster can switch, where the network list includes at least one PLMN, such as an identifier of the at least one PLMN, and where a first PLMN is a PLMN with a highest priority among the at least one PLMN.

It will be appreciated that the RAN device may also obtain the network list directly from the AMF network element in mode 1. For mode 2, since the SOR procedure is generally initiated by the terminal, the difference in the present application is that the RAN equipment initiates the SOR procedure by proxy terminal to obtain the network list from the UDM network element.

S302, the RAN equipment sends indication information to N bonding silver wire equipment.

The indication information is used for indicating that target bonding wire devices in the N bonding wire devices need to be switched from NPN to be connected to a first public land mobile network PLMN, and the indication information is also used for indicating that other bonding wire devices except the target bonding wire devices in the N bonding wire devices need to be connected with the target bonding wire devices through a PC5, wherein the first PLMN is a public network. For example, the RAN device may send first indication information to a target bonded silver device of the N bonded silver devices, where the first indication information indicates that the target bonded silver device needs to be switched from the NPN to the access to the first PLMN by carrying an identifier of the first PLMN, where the first PLMN stores in advance subscription data of the target bonded silver device in the first PLMN, so as to support that the target bonded silver device can be switched from the NPN to the access to the first PLMN. The RAN device may also send second indication information to N-1 other bonding wire devices in the N bonding wire devices, where the second indication information indicates, by carrying an identifier of the target bonding wire device, that the N-1 other bonding wire devices need to establish a PC5 connection with the target bonding wire device.
