Example 1
Fig. 1 is a schematic diagram of an optional scenario architecture of a 5GC and an MEP in linkage according to the related art, wherein the 5GC is generally provided by a CT enterprise, and the MEP is generally provided by a cloud computing or other IT enterprise, and split transmission is performed between the two through a standard internet interface protocol; however, in a 5G private network scenario, if a scheme of separate CT and IT design is still adopted, since different enterprise-designed equipment products are different, an interface between the two is difficult to define, and network capability information is inconvenient to transmit, for example, 5GC capability information required by MEP cannot be transmitted, and flexibility and extensibility are poor.
In order to solve the above problem, an embodiment of the present application provides a new communication system in which a 5GC is linked with an MEP, as shown in fig. 2, the system includes:
5GC module 20, which includes UPF entity 200, configured to receive service request information of AF module 220, and send network capability information corresponding to the service request information to AF module 220 according to the service request information;
the 5GC module 20 may further include: NEF entities, SMF entities, etc.
The MEP module 22 includes an AF module 220, configured to receive service request information sent by the UE, obtain network capability information corresponding to the service request information from the UPF entity 200, and provide a service corresponding to the service request information for the UE according to the network capability information.
It should be noted that the functions of the AF module in the MEP and the AF entity in the core network may be the same or different, and the AF module is a virtual function module designed based on IaaS.
As can be seen from fig. 3, the 5GC and the MEP are both designed based on IaaS, and both are upper bearer function modules, and the UPF entity 200 and the AF module 220 may implement fast and convenient transmission of network capability information in a custom protocol manner, where in some optional embodiments of the present application, the network capability information includes at least one of the following: cell Load capacity (Cell Load), signal-to-noise ratio (SINR), quality of service (QoS), Throughput (Throughput), Location (Location).
Specifically, the AF module 220 may receive the network capability information in various ways, for example:
the AF module 220 receives an IP data packet from the UPF entity 200; the network capability information is obtained from the extension header of the IP data packet, that is, an in-band flow following manner is adopted, and the information can be encapsulated into the original data flow in a specific format by means of an encapsulation protocol such as customized or GRE, or an IPv6 extension header.
Optionally, the network capability information may also be received in an out-of-band proprietary manner: the AF module 220 receives a dedicated message from the UPF entity 200, wherein the dedicated message is a message dedicated to transmitting network capability information; and acquiring the network capacity information from the special message, wherein the special message carries the IP data flow identification corresponding to the network capacity information. It can thus be seen that the out-of-band proprietary approach can use a customized protocol along with a particular data stream identification to associate the IP data streams and communicate the above information.
In the operating environment shown in fig. 2, an embodiment of the present application provides a data communication method, as shown in fig. 3, the method at least includes steps S302-S306, where:
step S302, the AF module in the MEP receives the service request information sent from the UE.
In an optional embodiment of the present application, an AF module in an MEP receives service request information sent by a UE, where the service request information carries target network capability information. For example, after the UE starts a corresponding video playing APP, it detects a definition selection instruction from the user, that is, the user has a requirement on the definition of the played video, generates a service request message based on the definition selected by the user, and sends the service request message to the AF module in the MEP, where the AF module completes definition adjustment according to the acquired network capability information of the core network device.
Step S304, the AF module acquires network capability information corresponding to the service request information from the core network device.
In an optional embodiment of the present application, the AF module receives network capability information from a UPF entity in the core network device, where the network capability information includes at least one of the following: cell load capability, signal-to-noise ratio, throughput, positioning information, QoS enforcement, etc.
After the AF module acquires the network capability information from the UPF entity, the network capability information is packaged according to a format supported by the PaaS, and the packaged network capability information is used as the capability information of the PaaS equipment.
In an optional embodiment of the present application, the UPF entity receives network capability information from an NEF entity in the core network device, and then transmits the network capability information to an AF module of the MEP, where the NEF entity determines the network capability information according to preset configuration information, where the preset configuration information includes: and collecting and formulating network capacity information periodically according to a preset period.
Specifically, the NEF entity periodically collects and formulates the relevant network information and capabilities (such as positioning information, QoS execution conditions, etc.) of the user, and then sends the relevant network information and capabilities to the SMF entity through the service interface, and the relevant network information and capabilities are sent to the UPF entity by the SMF entity, and then are called by the AF module in the MEP.
In an alternative embodiment of the present application, the UPF entity may also generate the network capability information locally. Specifically, the method comprises the following steps: the UPF entity generates network capacity information based on a local flow management strategy and sends the generated network capacity information to an AF module; alternatively, the UPF entity receives network capability information from the base station apparatus. The local traffic management policy is a policy for identifying and classifying data flows, and implementing traffic control, optimization, and traffic guarantee for a key service, based on a traffic condition and a traffic management and control policy of a network, and includes but is not limited to Qos management, and may specifically include management of the following dimensions:
1) time delay: latency refers to the transmission time required for an IP packet to reach a network egress point from a network ingress point. Some time-sensitive applications, such as real-time voice services and video services, have the most stringent delay requirements. The main factors contributing to network latency can be simply divided into network-generated latency and device-generated latency. The delay generated by the device generally refers to the delay generated when the device processes the service data, which has a great relationship with the performance of the device, including devices of various layers of the network, such as SDH devices, routing devices, media gateways, and the like. Network-generated delays include both fundamental transmission delays (i.e., the inherent delay required for an electrical or optical signal to travel over a physical medium) and link rate delays (i.e., the delay generated when the link rate is lower than the data transmission rate). Due to the best effort nature of IP networks, both device-induced delays and network-induced delays are also related to the data traffic conditions in the actual network. When the data volume is large and the network and the device are fully operational. The resulting congestion and queuing, scheduling and forwarding delays will increase significantly.
2) Dithering: when a transmitting end transmits a compressed and packed voice signal in an IP network, the transmission paths of the data packets may be different, so that the arrival time of different data packets at a receiving end may be different, which causes a discontinuous situation, called jitter, when the receiving end plays back the voice signal. The receiving end can compensate the influence of jitter by increasing the receiving buffer. But the size of the jitter buffer will affect both jitter and delay. If jitter has an impact on speech quality, increasing the size of the jitter buffer reduces jitter to an acceptable level; but if the buffer is too large, it will increase the delay and also make it unacceptable to the user. A typical jitter buffer generates a delay of 20ms but usually up to 80 ms. The size of the jitter buffer needs to be set according to the specific network conditions.
3) Packet loss rate: in general, data packets are dropped at the point where congestion occurs in the network, and erroneous packets generated in the transmission line are also dropped. Generally, when the number of received packets exceeds the size limit of the output port, congestion occurs, and thus, packet loss occurs. Packet loss can also result if there is not enough input buffering at the end of the packet arrival. The packet loss rate is generally defined as the percentage of packets that are dropped when a number of consecutive packets are transmitted in the network at certain time intervals. From the perspective of user experience, a packet loss rate generally higher than 2% is unacceptable.
4) Throughput: throughput refers to the transmission rate of IP packets in the network and may be expressed as an average rate or a peak rate. The throughput of the network is a measure of the ability of the network to forward IP packets, and depends mainly on the link rate, the port rate of the node device, and the service condition of the network.
5) Availability: availability refers to the percentage of time intervals that a user can use the IP service availability function over the entire time interval of the IP service. For example, within 5 consecutive min, if the packet loss rate provided by an IP network is less than or equal to 75%, the time period is considered to be available, otherwise it is not available. Availability is mainly used for measuring the capability of a network device and a link to normally provide services and determining whether the network device and the link can support continuously available packet transmission services.
In an optional embodiment of the present application, the AF module receives a custom communication protocol message from the core network device, where the custom communication protocol message carries network capability information corresponding to the service request information.
Specifically, the AF module receives an IP data packet from the UPF entity, where an extension field of the IP data packet carries network capability information, and the process is also called an in-band flow, that is, the network capability information may be encapsulated into an original data flow in a specific format by using an encapsulation protocol such as customized or GRE, or an IPv6 extension header.
Optionally, the network capability information may also be transmitted in an out-of-band proprietary manner, and the AF module receives a dedicated message from the UPF entity, where the dedicated message is a message dedicated to transmitting the network capability information; the network capability information is obtained from the special message, wherein the special message carries the IP data stream identifier corresponding to the network capability information, that is, the out-of-band proprietary manner can use a customized protocol and a specific data stream identifier to associate the IP data stream and transmit the network capability information.
In an optional embodiment of the present application, the MEP and the core network device are both designed based on IaaS, that is, the MEP and the 5GC both carry a function module on the IaaS.
Step S306, the AF module provides the service corresponding to the service request information for the UE according to the network capability information.
In an optional embodiment of the present application, the AF module determines target network capability information required by the service request first; after obtaining the network capacity information from the UPF entity, comparing the network capacity information with the target network capacity information; if the network capability information is consistent with the target network capability information, the AF module provides a service corresponding to the service request information for the UE according to the network capability information; and if the network capability information is inconsistent with the target network capability information, generating prompt information for indicating that the network capability information is inconsistent with the target network capability information, and sending the prompt information to the UE. By adopting the means, the capability matching between the MEP and the core network equipment can be realized, and the reliability of communication can be ensured.
The AF module described above may be operated in the computer terminal (or mobile device) shown in fig. 4. As shown in fig. 4, the computer terminal 40 (or mobile device 40) may include one or more (shown as 402a, 402b, … …, 402 n) processors 402 (processor 402 may include, but is not limited to, a processing device such as a microprocessor MCU or a programmable logic device FPGA), memory 404 for storing data, and a transmission module 406 for communication functions. Besides, the method can also comprise the following steps: a display, an input/output interface (I/O interface), a Universal Serial Bus (USB) port (which may be included as one of the ports of the I/O interface), a network interface, a power source, and/or a camera. It will be understood by those skilled in the art that the structure shown in fig. 4 is only an illustration and is not intended to limit the structure of the electronic device. For example, the computer terminal 40 may also include more or fewer components than shown in FIG. 4, or have a different configuration than shown in FIG. 4.
It should be noted that the one or more processors 402 and/or other data processing circuitry described above may be referred to generally herein as "data processing circuitry". The data processing circuitry may be embodied in whole or in part in software, hardware, firmware, or any combination thereof. Further, the data processing circuit may be a single stand-alone processing module, or incorporated in whole or in part into any of the other elements in the computer terminal 40 (or mobile device). As referred to in the embodiments of the application, the data processing circuit acts as a processor control (e.g. selection of variable resistance termination paths connected to the interface).
The memory 404 may be used to store software programs and modules of application software, such as program instructions/data storage devices corresponding to the methods in the embodiments of the present application, and the processor 402 executes various functional applications and data processing by running the software programs and modules stored in the memory 404, so as to implement the vulnerability detection method of the application program. The memory 404 may include high-speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 404 may further include memory located remotely from the processor 402, which may be connected to the computer terminal 40 via a network. Examples of such networks include, but are not limited to, the internet, intranets, local area networks, mobile communication networks, and combinations thereof.
The transmission module 406 is used to receive or transmit data via a network. Specific examples of the network described above may include a wireless network provided by a communication provider of the computer terminal 40. In one example, the transmission device 406 includes a Network adapter (NIC) that can be connected to other Network devices through a base station so as to communicate with the internet. In one example, the transmission device 406 may be a Radio Frequency (RF) module, which is used for communicating with the internet in a wireless manner.
The display may be, for example, a touch screen type Liquid Crystal Display (LCD) that may enable a user to interact with a user interface of the computer terminal 40 (or mobile device).
In an alternative embodiment of the present application, a specific process of 5GC interacting with MEPs is shown in fig. 5, and the process includes steps S502-S512, where:
step S502, the AF module in the MEP receives the service request information sent from the UE.

The network information required by the MEP can be conveniently transmitted through an interface protocol between the UPF entity in the user-defined core network equipment and the AF module in the MEP, so that the technical problems that due to the fact that CT and IT are separately designed in a 5G private network scene, interfaces between different equipment products designed by different enterprises are difficult to define, and network capacity information expansion is inconvenient are solved.
