[0003] The present application relates to the field of communication technology, and specifically to a method, apparatus, device, and readable storage medium for processing artificial intelligence (AI) services. Background Art

[0004] Artificial intelligence has entered the application era and can help all walks of life complete various tasks and provide a variety of services. With the development of wireless mobile communication technology, artificial intelligence (AI) will become one of the pillar technologies of future mobile communication technology.

How to implement AI services in operator networks is an urgent problem to be solved.

[0060] The following will be combined with the accompanying drawings in the embodiments of this application to clearly describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0061] The terms "first", "second", etc. in this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same type, and do not limit the number of objects, for example, the first object can be one or more. In addition, "or" in this application represents at least one of the connected objects. For example, "A or B" covers three options, namely, Option 1: including A but not including B; Option 2: including B but not including A; Option 3: including both A and B. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0062] The term "indication" in this application can be either a direct indication (or explicit indication) or an indirect indication (or implicit indication). A direct indication can be understood as the sender explicitly informing the receiver of specific information, the operation to be performed, or the requested result, etc. in the instruction sent; an indirect indication can be understood as the receiver determining the corresponding information based on the instruction sent by the sender, or making a judgment and determining the operation to be performed or the requested result, etc. based on the judgment result.

[0063] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA) or other systems. The terms "system" and "network" in this application are often used interchangeably, and the technology described can be used for the systems and radio technologies mentioned above, as well as for other systems and radio technologies. The following description describes a New Radio (NR) system for example purposes, and NR terminology is used in most of the following description, but these technologies can also be applied to systems other than NR system applications, such as 6th Generation (6G) communication systems.

[0064] To facilitate understanding of the embodiments of the present application, the following technical points are first introduced below:

[0065] 1. About IP Multimedia Subsystem (IMS) data transmission.

[0066] In the fifth generation mobile communication technology system (5GS), IMS is a data network (DN). The terminal is connected to the user plane function (UPF) through the base station, and then enters the IMS core network through the proxy call session control function (P-CSCF).

[0067] The terminal establishes a PDU session dedicated to the IMS network. The Data Network Name (DNN) is the IMS network. When the terminal establishes the PDU session, the Session Management Function (SMF) discovers that it is the IMS DNN and establishes the PDU session and assigns the P-CSCF address and default Quality of Service (QoS) flow parameters to the terminal. This is because, from the perspective of 5GS, the P-CSCF is an application server (AS). When the terminal uses the service, the establishment of a dedicated QoS flow is dynamically triggered according to the QoS requirements of the application layer, which triggers the PDU session modification process and issues the dedicated QoS flow parameters.

[0068] The terminal uses the default QoS flow to transmit IMS signaling, such as Session Initialization Protocol (SIP) signaling, to negotiate some control parameters, and uses a dedicated QoS flow to transmit IMS data, such as audio and media streams.

Communication resources are a set of resources provided by the existing 3rd Generation Partnership Project (3GPP) to terminals or third parties for communication services, including but not limited to communication links, allocated and scheduled frequency bands, memory of base stations or network elements, signaling forwarding, and other resources.
