[0102] Figure 1 is a network device and terminal communication system architecture diagram according to an example embodiment. The communication method provided by the present disclosure can be applied to Figure 1 the communication system architecture diagram shown. As Figure 1 shown, the network side device can send signaling based on Figure 1 the architecture shown.

[0103] It can be understood that Figure 1The illustrated network device and terminal communication system is only illustrative, and other network devices can also be included in the wireless communication system, such as core network devices, wireless relay devices, wireless backhaul devices, and the like, which are not shown in Figure 1 The number of network devices and the number of terminals included in the wireless communication system are not limited in the embodiments of the present disclosure.

[0104] It can be further understood that the wireless communication system of the embodiments of the present disclosure is a network that provides wireless communication functions. The wireless communication system can use different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA), carrier sense multiple access with collision avoidance (CSMA / CA). Depending on the capacity, rate, latency and other factors of different networks, the network can be divided into 2G (English: generation) network, 3G network, 4G network or future evolution network, such as 5G network. The 5G network can also be referred to as a new radio network (New Radio, NR). For the convenience of description, the wireless communication network is sometimes referred to as a network in the present disclosure.

[0105] Further, the network device involved in the present disclosure can also be referred to as a wireless access network device. The wireless access network device can be a base station, an evolved node B (eNB), a home base station, an access point (AP) in a wireless fidelity (WiFi) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), or a transmission and reception point (TRP), etc., and can also be a gNB in an NR system, or can also be a component or a part of a device constituting a base station, etc. When it is a vehicle-to-everything (V2X) communication system, the network device can also be a vehicle-mounted device. It should be understood that the specific technology and specific device form adopted by the network device in the embodiments of the present disclosure are not limited.

[0106] Further, the terminal involved in the present disclosure can also be referred to as a terminal device, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc., and is a device that provides voice and / or data connectivity for a user, for example, a handheld device having wireless connection function, a vehicle-mounted device, etc. At present, some examples of the terminal are: a mobile phone, a pocket personal computer (PPC), a palm computer, a personal digital assistant (PDA), a notebook computer, a tablet computer, a wearable device, or a vehicle-mounted device, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device can also be a vehicle-mounted device. It should be understood that the specific technology and specific device form adopted by the terminal in the embodiments of the present disclosure are not limited.

[0107] With the rapid development of artificial intelligence technology, multi-modal interaction and multi-modal machine learning have become important research directions. Multi-modal technology needs to fuse and process multi-modal information to obtain better interactive experience and stronger machine learning capability. Each specific type of information or information storage representation form can be referred to as a modality. For example, human touch, hearing, vision, smell, etc. Among them, the multimedia data describing the same object, the same type of data information from different sensors, and the media. From a broad perspective, two different languages can also be considered as two modalities, and even the data sets collected in two different situations can also be considered as two modalities.

[0108] In the related art, the network defined by 3GPP processes multi-modal information as application layer data, and the cooperation between modes is handed over to the application layer for processing.

[0109] Therefore, in the related art, the application layer requires that the application layer can dynamically adjust the QoS requirement of each mode according to the network condition in the process of processing multi-modal data. However, not all application layers have this function, and if the application layer does not have the function of dynamically adjusting to meet the QoS requirement of multi-modal data, it may need to be realized through interaction with the 3GPP network, but the 3GPP network may not be able to meet the QoS requirement of multi-modal data according to the actual situation of the network.

[0110] Based on this, the present disclosure provides an application function session processing method, which sends the QoS update request of all terminals in multi-modal to the network by the application function.

[0111] In other words, the AF sends the QoS update request of all terminals in multi-modal to the policy control function (PCF) through the network exposure function (NEF), and the PCF uniformly controls the policy according to the QoS update request of all terminals.

[0112] Figure 2 is a flowchart of an application function session processing method according to an exemplary embodiment. As shown in Figure 2 The application function session processing method is used in a first network device, and includes the following steps.

[0114] In the embodiment of the present disclosure, the application function session quality of service update request includes the parameter information of the terminal group, wherein the terminal group includes one or more terminals. The first network device can be a network element or a node, and in the embodiment of the present disclosure, the first network device can be understood as an AF.

[0115] In an example embodiment of the present disclosure, the AF determines to send an application function session quality of service update request to a second network device (e.g., NEF) for updating QoS reservation resources for a group of terminals with required QoS and an established AF session.

[0116] In an example embodiment of the present disclosure, the parameter information of the terminal group includes at least one of the following:

[0117] an identifier of the application function;

[0118] a transaction reference ID;

[0119] a flow description mapped to the terminal group;

[0120] a QoS reference mapped to the terminal group; and

[0121] an alternative service requirement.

[0122] In an example embodiment of the present disclosure, a requested time period and / or traffic volume mapped to the terminal group can also be included in the application function session quality of service update request. It is determined that the transaction reference ID included in the application function session quality of service update request is set to the reference ID assigned by the NEF to create the application function session quality of service update request.

In the application policy authentication update request, any optional time period and / or traffic volume are also included, and are mapped to the data connection information of the terminal group.

[0135] In an implementation, the NEF fails to authenticate the application function session quality of service update request, and the NEF sends a result value of the authentication failure to the AF, so as to inform the AF that the application function session quality of service update request is not authorized through the result value of the authentication failure.

[0153] In the embodiments of the present disclosure, the PCF receives an application policy authentication update request and determines that the NEF authentication is successful. Based on the parameter information of the terminal group included in the application policy authentication update request, the parameter information of the required terminal group is determined, and then the quality of service parameter set mapped to the terminal group is determined. It is determined whether to allow updating the determined quality of service parameter set mapped to the terminal group.

[0154] In the embodiments of the present disclosure, the application policy authentication request includes a replacement service request, and the replacement service request includes one or more quality of service reference parameter sets mapped to the terminal group.

[0170] In an embodiment of the present disclosure, in response to the failed update of the service quality parameter set mapped to the terminal group, an application policy authentication update notification message is sent to indicate that the NEF fails to update the service quality parameter set mapped to the terminal group.

[0171] In an example embodiment of the present disclosure, the application function session processing method of the present disclosure is described by taking the interaction of a first network device (for example, an AF), a second network device (for example, an NEF), and a third network device (a PCF) as an example.

As shown in Figure 11As shown, the AF sends an application function session quality of service update request, and the NEF authenticates the application function session quality of service update request mapped to the terminal group. In response to successful authentication of the application function session quality of service update request, an application policy authentication update request is sent to the PCF. In the case of failed authentication of the application function session quality of service update request, the NEF sends a result value of the authentication failure to the AF, so as to inform the AF that the application function session quality of service update request is not authorized. The PCF receives the application policy authentication update request, and determines that the NEF is successfully authenticated. Based on the parameter information of the terminal group included in the application policy authentication update request, the PCF determines the required parameter information of the terminal group, and further determines a quality of service parameter set mapped to the terminal group. It is determined whether to update the determined quality of service parameter set mapped to the terminal group, and an application policy authentication update response mapped to the terminal group is sent. According to the successful update / identification of the quality of service parameter set mapped to the terminal group, an application policy authentication update notification message is sent. The NEF sends an application function session quality of service update response and an application policy authentication update notification message to the AF according to the received application policy authentication update response and the application policy authentication update notification message mapped to the terminal group.
