Detailed Description

Referring to fig. 1, a 5G network architecture as determined by the third generation partnership project (3rd Generation Partnership Project,3GPP) ts.23.501 may include nodes or network elements such as: UE, RAN equipment, user plane function (User plane Function, UPF) equipment, data Network (DN) control plane Network elements; the UE is a 5G terminal device, a control plane of the 5G network adopts a service-based architecture, and the control plane network element may include an authentication server function (Authentication Server Function, AUSF) entity, an access and mobility management function (Access and Mobility Management Function, AMF) entity, a session management function (Session Management Function, SMF) entity, a network slice selection function (Network Slice Selection Function, NSSF) entity, a network opening function (Network Exposure Function, NEF) entity, a network storage function (Network Repository Function, NRF) entity, a PCF entity, a unified data management (Unified Data Management, UDM) entity, and an AF entity. The UDM entity is used for realizing functions of user subscription data management, authentication information generation, mobility management, short message routing and the like; the AUSF entity is used to provide authentication related functions. In fig. 1, nausf, namf, nsmf, nnssf, nnef, nnrf, npcf, nudm, naf represents service interfaces provided by an AUSF entity, an AMF entity, an SMF entity, an NSSF entity, a NEF entity, an NRF entity, a PCF entity, a UDM entity, and an AF entity, respectively; n1, N2, N3, N4, N6, and N9 denote an N1 interface, an N2 interface, an N3 interface, an N4 interface, an N6 interface, and an N9 interface, respectively.

In the related art, an industry network may be implemented through a communication networking architecture of a 5G network and an industrial internet, referring to fig. 2, each industry device may access the 5G network through a 5G gateway or a 5G client terminal device (Customer Premise Equipment, CPE); for example, the industry device may be connected to the 5G CPE by using a WIFI communication method, a wired communication method, or the like. The 5GCPE may access the 5G network via the SIM card such that end-to-end communication is completed. The network elements of the network referring to fig. 2,5G may include network elements of next generation base stations (the next Generation Node B, gNB), 5G core network (5 GC). Illustratively, the network elements of the 5GC may include management and orchestration function (Management and Orchestration, MANO) entities, network element management system (Element Management System, EMS) entities, UPF devices, NRF entities, AMF entities, SMF entities, PCF entities, UDM entities, and the like. Illustratively, the 5GC may access the internet through the chinese mobile internet (China Mobile Network, CMNET).

In the communication networking architecture shown in fig. 2, industry equipment does not need to be changed, and the introduction of the 5G network in the peer-to-peer architecture can be made imperceptible.

When industrial equipment sends a PLC message or an IO message, the 5G gateway can realize the forwarding of the PLC message or the IO message; when monitoring the sending condition of a PLC message or an IO message of industrial equipment, the random jitter can occur at the sending interval of the PLC message or the IO message, so that the jitter occurs when the message reaches an air interface; referring to fig. 3, in a scenario of transmitting a single PLC message or a single IO message, when a time point of transmitting any one PLC message or any one IO message is T1, random jitter may occur at a time point of next transmitting the single PLC message or the single IO message, for example, it may be T2, T3 or T4 shown in fig. 3.

In fig. 4, arrows filled with different patterns respectively represent transmission time points of different types of PLC messages or different types of IO messages, it can be seen that, in a scenario where multiple PLC messages or multiple IO messages are concurrent, a transmission time interval of any one PLC message or any one IO message does not completely conform to a reserved transmission time interval (Transmission Time Interval, TTI) time slot, a situation that a message arrives randomly occurs, and peak-to-average ratio is high due to the concurrence of multiple PLC messages or multiple IO messages. In order to make the air interface scheduling opportunity accurately match the arrival time of the PLC message or the IO message, and avoid introducing cache waiting caused by missing scheduling opportunities, the 5G network needs to reserve multiple resources for each PLC text or IO message, or reserve multiple uplink scheduling opportunities.

The reasons for random jitter of the arrival time of the message after preliminary analysis include: the PLC equipment, the IO equipment and the 5G network are not strictly time-synchronized, the PLC equipment or the IO equipment sends data packets based on a local crystal oscillator, and the problem of insufficient stability exists; in an industry application scenario, a cycle period (CT) of sending a PLC message or an IO message is generally about 10ms, and a wire transmission delay is shorter, for example, the wire transmission delay is less than or equal to 1ms, and a wire concurrency capability is sufficient, so that a Time point of sending the PLC message or the IO message is not required to be strictly constrained to have no jitter. But for 5G wireless transmission scenarios, more redundant radio resources need to be reserved for the 5G air interface to match the jittered message arrival times and unpredictable multi-user concurrency. Such traffic patterns would undoubtedly be seen as inefficient use of radio resources for 5G resources.

Step 504: the UE receives the time slot proposal; the time slot for transmitting data is determined according to the time slot proposal.

In the embodiment of the present application, after receiving the timeslot proposal, the UE may select an adopted timeslot from at least one timeslot list according to the timeslot proposal, where the selected timeslot is the received timeslot proposal. After the UE selects the adopted timeslot, the timeslot proposal can be confirmed through interaction with the RAN device, and then the timeslot for transmitting data can be determined according to the timeslot proposal.

In some embodiments of the present application, the AF entity or the service orchestration server may further obtain first information, where the first information includes a usage pattern of the service information or a receiving object of the service information.

Illustratively, the AF entity or the service orchestration server may obtain the first information when obtaining the service information; alternatively, the first information may be acquired after the service information is acquired.

Here, the service information is used in a manner of using the service information in the 5G network, for example, the service information is used for RAN to perform service scheduling and reserve TTI resources. The receiving object of the service information is a receiving object of the service information in the 5G network, for example, the receiving object of the service information is RAN equipment of a service associated with the service information.

Accordingly, the process of sending service information to the RAN device by the AF entity or the service orchestration server may include: transmitting the service information to RAN equipment by transmitting the service information and the first information to a Policy Control Function (PCF) entity; the first information is used by the PCF entity to determine whether traffic information needs to be sent to the RAN device.

In the embodiment of the application, after receiving the service information and the first information, the PCF entity can determine whether to send the service information to the RAN device according to the first information, or can determine which RAN device to send the service information to according to the first information. The PCF entity forwards the service information to the RAN equipment, so that the RAN equipment can conduct service arrangement and resource reservation according to the service information.

In some embodiments of the present application, the identity of the RAN equipment may also be obtained; for example, the identification of the RAN device is the ID of the RAN device. Accordingly, the AF entity or the service orchestration server may send service information to the RAN device according to the identity of the RAN device.

Illustratively, the AF entity or the service orchestration server may obtain the identity of the RAN device when obtaining the service information; alternatively, the identification of the RAN device may be obtained after the service information is obtained.

In some embodiments of the present application, the RAN device may receive service information sent by the AF entity or the service orchestration server through a direct transmission manner; alternatively, the RAN device may receive service information forwarded by the AF entity or the service orchestration server through the NEF entity.

Illustratively, when the traffic orchestration server is an intra-operator server, the traffic orchestration server need not forward the traffic information to the RAN device through the NEF entity, but may send the traffic information to the RAN device through a direct transmission.

Illustratively, where the traffic orchestration server is not an operator internal server, but is a third party server, the traffic orchestration server may forward traffic information to the RAN device through the NEF entity

It can be seen that, in the embodiment of the present application, the RAN device may receive the service information through multiple data transmission modes, that is, the RAN may receive the service information more flexibly according to the requirements of the actual scenario.

In this way, the RAN device may send a reasonable timeslot suggestion to the UE during the registration process or the session establishment process of the UE, so that data may be sent during the registration process or the session establishment process of the UE in a reasonable timeslot, which is beneficial to optimizing the service transmission performance during the registration process or the session establishment process of the UE.
