Fig. 1 shows a schematic diagram of a mobile communication system provided by an exemplary embodiment of the present application. The mobile communication system 100 may include: a user terminal (User Equipment, UE), a radio access network (Radio Access Network, RAN), a core network (Core) and an application function (Application Function, AF). Among them, UE, RAN, and Core are the main components of the architecture. Logically, they can be divided into two parts: the user plane and the control plane. The control plane is responsible for the management of the mobile network, and the user plane is responsible for the transmission of service data. In the figure, the NG2 reference point is located between the RAN control plane and the Core control plane, the NG3 reference point is located between the RAN user plane and the Core user plane, and the NG6 reference point is located between the Core user plane and the data network.

UE: It is the entrance for mobile users to interact with the network. It can provide basic computing capabilities and storage capabilities, display service windows to users, and accept user operation inputs. The UE will adopt the next-generation air interface technology to establish a signal connection and a data connection with the RAN, thereby transmitting control signals and service data to the mobile network.

RAN: Similar to the base station in the traditional network, it is deployed close to the UE to provide network access functions for authorized users in a specific area, and can use different quality transmission tunnels to transmit user data according to user levels and service transmission requirements. RAN can manage its own resources, use them reasonably, provide access services for UEs as needed, and forward control signals and user data between UEs and the core network. In various embodiments of the present application, the network transmission capability is the transmission capability of the RAN. The transmission capability includes: at least one of transmission bandwidth, transmission rate, and QoS.

Core: Responsible for maintaining the subscription data of the mobile network, managing the network elements of the mobile network, and providing functions such as session management, mobility management, policy management, and security authentication for the UE. When the UE is attached, it provides network access authentication for the UE; when the UE has a service request, it allocates network resources for the UE; when the UE moves, it updates the network resources for the UE; when the UE is idle, it provides a quick recovery mechanism for the UE; When the UE is deattached, it releases network resources for the UE; when the UE has business data, it provides data routing functions for the UE, such as forwarding uplink data to the data network (Data Network, DN), or receiving UE downlink data from the DN, forwarding to the RAN and thereby sent to the UE.

AF: various services at the application layer, which can be the operator's internal AF or a third-party AF (such as video server, game server); AF determines the transmission requirements of business data streams. For example, the AF determines the transmission requirements of the service data flow according to the type of the service data flow, the delay requirement, and the priority.

Exemplarily, the AF determines the transmission requirement of the service data flow according to the network transmission capability of the RAN, so that the RAN can carry the transmission of the service data flow, that is, the transmission requirement of the service data flow meets the network transmission capability.

Figure 2 is the detailed architecture determined on the basis of Figure 1, where the core network user plane includes: User Plane Function (UPF); the core network control plane includes: Authentication Server Function (Authentication Server Function, AUSF), interface Access and Mobility Management Function (AMF), Session Management Function (SMF), Network Slice Selection Function (NSSF), Network Exposure Function (NEF) , Network Function Repository Function (NF Repository Function, NRF), Unified Data Management (Unified Data Management, UDM), Policy Control Function (Policy Control Function, PCF). The functions of these functional entities are as follows:

UPF: perform user data packet forwarding according to SMF routing rules; AUSF: perform UE security authentication; AMF: UE access management and mobility management; SMF: UE session management; NSSF: select network slices for UE; NEF: Northbound Open the network function to the third party through the API interface; NRF: provide the storage function and selection function of network function entity information for other network elements; UDM: user subscription context management; PCF: user policy management.

In the architecture shown in Figure 2, the N1 interface is the reference point between the UE and the AMF; the N2 interface is the reference point between the RAN and the AMF, and is used for sending NAS messages; the N3 interface is the reference point between the RAN and the UPF, Used to transmit user plane data, etc.; N4 interface is the reference point between SMF and UPF, used to transmit information such as tunnel identification information, data cache indication information, and downlink data notification messages of N3 connections; N6 interface is UPF and UPF The reference point between DNs is used to transmit user plane data, etc.

There are generally multiple UEs, and one or more UEs may be distributed in a cell managed by each RAN. UE may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem with wireless communication functions, as well as various forms of user equipment, mobile stations (Mobile Station, MS), etc. . For convenience of description, the devices mentioned above are collectively referred to as UE. The RAN and the UE communicate with each other through some air technology, for example: User to Network interface Universal (Uu). The RAN and AMF communicate with each other through some air technology, such as the N1 interface in the fifth generation mobile communication technology (5th Generation, 5G) new air interface (New Radio, NR) system.

The number of RANs is usually multiple. RAN includes radio access network (Radio Access Network, RAN). The access network in the 5G NR system can be called the New Generation-Radio Access Network (NG-RAN). The RAN is a device that provides wireless communication functions for UEs. RAN may include various forms of macro base stations, micro base stations, relay stations, access points and so on. In systems using different radio access technologies, the names of devices with RAN functions may be different. For example, in 5G NR systems, they are called 5G base stations (Next Generation Node B, gNodeB or gNB). As communication technology evolves, the term "access network equipment" may change.

The UE connects to the RAN at the access layer through Uu, exchanges access layer information and performs wireless data transmission, and the UE performs a Non-access Stratum (Non-access Stratum, NAS) connection with the AMF through the N1 interface to exchange NAS messages. In addition to performing mobility management on the UE, the AMF is also responsible for forwarding information related to session management between the UE and the SMF. The PCF is responsible for formulating policies related to UE mobility management, session management, and charging. The UPF performs data transmission with the DN through the N6 interface, and performs data transmission with the RAN through the N3 interface.

The "5G NR system" in the embodiments of the present disclosure may also be called a 5G system or an NR system, but those skilled in the art can understand its meaning. The technical solution described in the embodiments of the present disclosure can be applied to the 5G NR system, and can also be applied to the subsequent evolution system of the 5G NR system.

The terminal and the user equipment (User Equipment, UE) in the embodiments of the present disclosure express the same meaning, and the two can be replaced with each other.

It should be noted that the name of the interface between each network element in FIG. 1 and FIG. 2 is just an example, and the name of the interface in a specific implementation may be another name, which is not specifically limited in this embodiment of the present application. The names of network elements (such as SMF, AF, UPF, etc.) included in FIG. 1 and FIG. 2 are only examples, and do not limit the functions of the network elements themselves. In the fifth generation mobile communication system (5th Generation System, 5GS) and other networks in the future, the above-mentioned network elements may also have other names, which are not specifically limited in this embodiment of the present application. For example, in a 6G network, some or all of the above-mentioned network elements may use the terms in 5G, or may use other names, etc., which will be described in a unified manner here, and will not be described in detail below. In addition, it should be understood that the name of the message (or signaling) transmitted between the above network elements is only an example, and does not constitute any limitation on the function of the message itself.

Next, combined with the network architecture shown in Figure 2, the quality of service (Quality of Service, QoS) management and feedback in the 5G system will be introduced.

In related technologies, before the transmission of the service data flow starts, the AF at the opposite end of the UE provides the PCF with the transmission requirements of the service data flow. Among them, if the AF is trusted by the operator, it can directly provide information to the PCF, and if it is a third-party AF that is not trusted by the operator, it can provide information to the PCF through the Network Exposure Function (NEF). Exemplarily, the transmission requirements of the service data flow include: flow description information for service data flow detection, for IP type data packets, the IP type data packets are generally composed of source address, destination address, source port number, destination port IP quintuple information composed of numbers and protocol types above the IP layer. The transmission requirements of the service data flow also include: QoS-related requirements. Exemplarily, the QoS-related requirements include, but are not limited to, at least one of the following information: bandwidth requirements, and service types. The PCF formulates policy and charging control (Policy and Charging Control, PCC) rules based on the information received from the AF and sends them to the SMF. The SMF determines the appropriate QoS flow for the received PCC rule, which is used to transmit the service data flow corresponding to the PCC rule, and provides QoS guarantee for the transmission of the service data.

The SMF provides the QoS flow parameters of each QoS flow to the RAN. Exemplarily, the QoS flow parameters include at least: 5G QoS identifier (5G QoS Identifier, 5QI), address resolution protocol (Address Resolution Protocol, ARP), and the QoS flow parameters also Including: code rate requirements.

5QI is an index value of QoS characteristics that can correspond to delay and bit error rate requirements, and Table 1 shows an example of 5QI.

ARP provides QoS flow allocation for RAN or keeps resource priority. For each QoS flow, the RAN guarantees the transmission requirements of the QoS flow according to the QoS flow parameters received from the SMF.

Table I

5QI time delay BER 66 100ms 1%

The concept of candidate QoS flow configuration is introduced in the 5G network, which is only used for guaranteed bit rate (Guaranteed Bit Rate, GBR) type QoS flows. For each QoS flow, SMF provides QoS flow parameters to RAN, and can also provide Provide multiple candidate QoS flow configurations with priority order. RAN guarantees the transmission requirements of service data flows according to the QoS flow parameters received from SMF. If the transmission requirements cannot be guaranteed, RAN selects candidates according to priority order QoS flow configuration guarantees the transmission requirements of service data flows according to the selected candidate QoS flow parameters, and the RAN can also inform the AF of the candidate QoS flow parameters adopted.

In related technologies, due to lack of time information, abnormal situations may occur in the transmission of data streams at certain time points. For example, when multiple service data streams are transmitted, multiple service data streams are sent at the same time point. This leads to a shortage of network resources allocated to each service data flow. However, in a longer period of time, the network transmission capacity can guarantee the transmission requirements of each business data stream, and abnormal situations during the transmission of business data streams can be avoided.

In the following, the technical solution of the present application will be described through several embodiments.

Figure 3 provides a flowchart of a method for information transmission provided by an embodiment of the present application, in which the first network element may be a device in the wireless access network shown in Figure 1, such as a base station, the method includes:

The network transmission capability is used to describe the carrying capacity of the network for the service data flow corresponding to the service request. Exemplarily, in the wireless communication network architecture, the service request is sent by the AF to the PCF. In various embodiments of the present application, the network transmission capability is the transmission capability of the radio access network.

Determining the time-based network transmission capability information by the first network element may be determining time-based network transmission capability information for all service requests, or determining time-based network transmission capability information for some service requests.

In this embodiment, the time-based network transmission capability information includes at least one time-corresponding network transmission capability information. At least one time includes a current time and/or a future time after the current time. Exemplarily, time may be understood as a moment, a time period, or a time slice, which is not limited in this embodiment. For example, the time includes time 12:00; or, the time includes a time slice with a length of 1 ms; or, the time includes a time segment with a length of 10 seconds.

For example, the time-based network transmission capability information includes network transmission capability information corresponding to 12:00:00. Exemplarily, the time-based network transmission capability information includes network transmission capability information respectively corresponding to m times, where m is an integer greater than 1.

Exemplarily, the information of the GPS clock is used to directly indicate the time.

For example: time-based network transmission capability information is: [12:00:00, 50MHz; 12:00:01, 80MHz], indicating that when the GPS clock is 12:00:00, the available transmission bandwidth of the network is 50MHz; GPS When the clock is 12:00:01, the available transmission bandwidth of the network is 80MHz.

• Use "start time + period" to implicitly indicate time.

Exemplarily, the information of the GPS clock is used to represent the time of the first time-based network transmission capability information, that is, the information of the GPS clock is used to represent the start time, and the time of the i-th time-based network transmission capability information is: start time+ Period length*(i-1), i is an integer greater than or equal to 2.

For example: set the cycle length of time-based network transmission capability information to 10ms, set the effective time length of time-based network transmission capability information to 1ms, when the GPS clock is 12:00:00, the time-based network transmission capability The information is: [50MHz, 20MHz, 0MHz, 0MHz, 50MHz, 20MHz, 50MHz, 100MHz, 0MHz, 0MHz], indicating that at the first ms starting at 12:00:00, the available transmission bandwidth of the network is 50MHz; at the second ms, the network The available transmission bandwidth is 20MHz; at 3ms, the available transmission bandwidth of the network is 0MHz, and so on.

In this embodiment, no limitation is imposed on the parameters included in the network transmission capability information. Exemplarily, the parameters included in the network transmission capability information include but are not limited to at least one of the following parameters: transmission bandwidth, transmission rate, and QoS.

In this embodiment, no limitation is imposed on the granularity of the time-based network transmission capability information. Exemplarily, the time-based network transmission capability information is based on service granularity, or based on user granularity, or based on carrier granularity, that is, the granularity of time-based network transmission capability information includes but is not limited to the following granularity:

When describing with a single service, the time-based network transmission capability information of different services may be the same or different. When describing based on the granularity of each service, the time-based network transmission capability information of each service is the same. For example, for service 1, the time-based network transmission capability information includes a transmission bandwidth of 30 MHz; for service 2, the time-based network transmission capability information includes a transmission rate of 168 Mbps; for service 3, the time-based network transmission capability information includes a transmission bandwidth 15MHz; for each service, the time-based network transmission capability information includes a transmission bandwidth of 20MHz.

When describing with a single user, the time-based network transmission capability information of different users may be the same or different. When describing based on the granularity of each user, the time-based network transmission capability information of each user is the same. For example, for user 1, the time-based network transmission capability information includes a transmission bandwidth of 80 MHz; for user 2, the time-based network transmission capability information includes a transmission rate of 330 Mbps; for user 3, the time-based network transmission capability information includes a transmission bandwidth 30MHz; for each user, the time-based network transmission capability information includes a transmission bandwidth of 50MHz.

• Based on carrier granularity.

Time-based network transmission capability information is described at the granularity of a single carrier or each carrier. When a single carrier is used for description, the time-based network transmission capability information of different carriers may be the same or different. When describing based on the granularity of each carrier, the time-based network transmission capability information of each carrier is the same. For example, for carrier 1, the time-based network transmission capability information includes a transmission bandwidth of 20 MHz; for carrier 2, the time-based network transmission capability information includes a transmission rate of 100 Mbps; for carrier 3, the time-based network transmission capability information includes a transmission bandwidth 20MHz; for each carrier, the time-based network transmission capability information includes a transmission bandwidth of 25MHz.

Optionally, the network transmission capability information includes: information on whether the transmission requirement is met, that is, the network transmission capability can be described in the dimension of whether the network transmission capability meets the transmission requirement of the service data flow. Exemplarily, in the wireless communication network architecture, the transmission requirement is sent by the AF to the PCF, and the QoS parameter sent by the SMF to the first network element carries the transmission requirement. Exemplarily, the transmission requirements include but are not limited to at least one of the following requirements: transmission bandwidth requirements, transmission rate requirements, and QoS requirements.

For example: the network transmission capability information is: [1, 0, 0, 1, 0, 0, 1, 0, 1]; where 1 means that the transmission requirements are met, and 0 means that the transmission requirements are not met, that is, in the first, the first The 4th, 7th and 9th time slots can meet the transmission requirements.

Step 320: the first network element sends time-based network transmission capability information.

Exemplarily, in the wireless communication network architecture, the first network element sends the time-based network transmission capability information to the SMF, and the SMF sends the time-based network transmission capability information to the PCF.

To sum up, the method provided in this embodiment can obtain accurate network transmission capability information at various time points within a period of time by using time information to correspond to network transmission capability information. The transmission requirements of business data streams can be targeted at each time point, and the selection range of time for business data stream transmission can be expanded to avoid abnormal situations during the transmission of business data streams and ease the network for centralized transmission of business data streams The pressure increases the utilization rate of the network transmission capacity.

Next, the parameters included in the network transmission capability information are introduced in detail: In each embodiment of the present application, no limitation is imposed on the parameters included in the network transmission capability information. Exemplarily, the parameters included in the network transmission capability information include but are not limited to at least one of the following parameters: transmission bandwidth, transmission rate, and QoS.

· Transmission bandwidth;

Exemplarily, the transmission bandwidth includes but is not limited to: the size of the available transmission bandwidth, or the ratio between the available transmission bandwidth and the network bandwidth resource.

The network transmission capacity information is: [12:00:00, 30%; 12:00:01, 60%], which means that when the GPS clock is 12:00:00, the available transmission bandwidth of the network is 30% of the network bandwidth resources ; When the GPS clock is 12:00:01, the available transmission bandwidth of the network is 60% of the network bandwidth resources.

·Transmission rate;

The transmission rate indicates the number of bits transmitted per unit time.

It should be noted that there is no limitation on the time unit corresponding to the transmission rate, and the time unit corresponding to the transmission rate includes but not limited to: second, time slot, frame or subframe.

Exemplarily, the network transmission capability information is: [168, 330, 0, 0, ..., 168, 168, 0, 0] Mbps, indicating that a duration is 10ms, sub-carrier space (sub-carrier space, SCS) = 30KHz , the borne transmission rates of 20 time slots are: 168Mbps, 330Mbps, 0Mbps, 0Mbps, ..., 168Mbps, 168Mbps, 0Mbps, 0Mbps.

· QoS.

Exemplarily, in the case where the available transmission bandwidth of the first time slot and the second time slot is 50 MHz, other time slots are MHz, and the user's reference modulation code is 16QAM, 1/2, the network transmission capability is able to support The cycle is 20ms, the transmission rate is 336Mbps, the delay is 1ms, and the reliability is 90% of the service data flow. It can support business data flow that is close to and lower than the above-mentioned transmission requirements. In the case of QoS=83, the obtained network transmission capacity does not match the QoS, and the network transmission capacity can be equivalently converted. For example, the network transmission capacity with a transmission rate of 336Mbps and a reliability of 90% can be approximately equal to The effect is a network transmission capability with a transmission rate of 168Mbps and a reliability of 99.99%.

To sum up, the method provided in this embodiment shows the specific parameters included in the network transmission capability information, uses at least one of transmission bandwidth, transmission rate, and QoS to describe the network transmission capability, and enriches the dimension of describing the network transmission capability .

For example, the application layer applies to the network layer to establish the first QoS radio bearer, and the network layer feeds back the transmission time that can meet the first QoS requirement. For example, the application layer applies to the network layer to establish a wireless bearer with QoS=82, and the network layer feeds back the transmission time pattern that can support the QoS requirement within 2 wireless frames (odd frame + even frame) as [1, 0, 0, 1, 0, 0, 1, ..., 1, 0], where 1 means yes and 0 means no.

The starting time is also indicated to the application layer by the network layer. The application layer determines the service generation time based on the transmission time list meeting the QoS requirements. For example, the transmission time pattern for supporting the QoS requirement reported by the network is: [1, 0, 0, 1, 0, 0, 1, ..., 1, 0], the application layer is in the fourth time slot of the odd radio frame Start to generate services with a period of 20m.
