[0066] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without any creative work fall within the scope of protection of the present application.

[0067] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be exchanged under appropriate circumstances, 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", "second", etc. are generally of a kind and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0068] It is worth noting that the technology described in the embodiments of the present application is not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be applied to 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) and other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described technology can be applied to the above-mentioned systems and radio technologies, as well as other systems and radio technologies. However, the following description describes a New Radio (NR) system for example purposes, and NR terminology is used in most of the following description, and these technologies can also be applied to applications other than NR system applications, such as 6th Generation (6G) communication systems. th

[0069] In order to better understand the scheme of the embodiments of the present application, first, the following is explained:

[0070] The network architecture to which the embodiments of the present application are applied is specifically described in Figure 1a and Figure 1b ;

[0071] As Figure 1a ​As shown, since the release of communication resources and computing resources needs to be considered, in the embodiments of the present application, a computing resource node (or also referred to as a computing storage resource node) or other new functional entity is added in the network architecture to provide one or both of the computing resources and the storage resources. Accordingly, in the current communication system, a user plane channel of UE-gNB-UPF (PDU session) is established for the user to provide the user with communication services, and the established PDU session needs to meet the communication service requirement (Quality of Service, QoS) of the user; in the embodiments of the present application, a computing session of UE-gNB-UPF-computing node is established for the user to provide the user with communication computing services, and the computing session needs to meet the computing service requirement of the user, that is, the communication QoS and the computing QoS of the computing service. There are multiple computing bearers in the computing session, and each computing bearer has its own computing QoS and communication QoS, which need to meet the roundtrip delay requirement and the computing service requirement. The computing session can also be referred to as a PDU session in the implementation, that is, it is implemented in the manner of an enhanced PDU session.

[0072] It should be noted that the resource release for the computing session in the embodiments of the present application can be to release all resources, that is, to release all communication resources and computing resources at the same time; or the resource release for the computing session can also be to release part of the resources, that is, to release the computing resources and the communication resources of a certain computing task in multiple computing tasks.

[0073] As shown in Figure 1b , a network architecture of an embodiment of the present application is shown, which involves network elements including: a terminal (User Equipment, UE), a mobility management function (Access and Mobility Management Function, AMF), a session management function (Session Management Function, SMF), a computing power management function (which can also be referred to as a computing power management network element), and a policy management function (Policy Control Function, PCF); wherein the computing power management function is a newly added network element for managing the computing power resources (including computing resources and storage resources) on the computing storage resource node (which can also be referred to as a computing node), as shown in Figure 1b , the SMF can manage the user plane function (User Plane Function, UPF), that is, allocate the UPF side communication resources and the base station side communication resources according to the communication QoS of the user, and the computing power management function can manage the computing storage resource node, that is, allocate the computing storage node resources according to the computing QoS of the user.

[0074] The method provided by the embodiments of the present application will be described in detail in combination with specific examples and application scenarios thereof with reference to the accompanying drawings.

[0075] Referring to Figure 2 The embodiments of the present application provide a method for releasing a computing session, which comprises the following steps:

[0076] Step 201: An SMF acquires a first message, the first message being used to request release of one or both of communication resources and computing resources in a computing session, and then step 202 and / or step 203 are executed;

[0077] Step 202: The SMF sends a second message to a PCF according to the first message, the second message being used to request deletion of a communication management policy;

[0078] Step 203: The SMF sends a third message to a computing management function according to the first message, the third message being used to request release of computing resources;

[0079] The computing session mentioned above is a session containing both communication resources and computing resources established by a wireless mobile network to meet the computing service requirements of a user. The computing session can provide the user with the computing service requested by the user while transmitting communication data for the user. There can be one to multiple computing bearers in the computing session, each computing bearer having its own computing QoS and communication QoS, and needing to meet both the roundtrip delay requirement and the computing service requirement. The computing session can also be referred to as a PDU session in implementation, that is, it is implemented in the manner of an enhanced PDU session. At this time, the computing bearer can also be referred to as a QoS flow or a bearer in implementation.

[0080] The SMF mentioned above is used for processing related to communication resources, and the computing management function is used for processing related to computing resources.

[0081] In a possible implementation, the computing resources mentioned above include computing resources and storage resources.

[0082] The first message mentioned above can be a Protocol Data Unit (PDU) session release request, a computing session release request, a computing resource release message, or a communication resource release message.

[0083] In the embodiments of the present application, there can be multiple cases in which the SMF acquires the first message, and the cases are as follows:

[0084] Case one: the SMF and the computing power management function obtain the first message at the same time, that is, the computing session release is executed by the SMF and the computing power management function together, then the SMF performs the processing of releasing the communication resource based on the first message, for example, requesting the PCF to delete the communication management policy, and the computing power management function performs the processing of releasing the computing power resource based on the first message, for example, requesting the PCF to delete the computing power management policy, which are collectively referred to as case one below;

[0085] Case two: the SMF obtains the first message, that is, the computing session release is executed by the SMF in a centralized manner, then the SMF performs the processing of releasing the communication resource based on the first message, and at the same time, the SMF sends a request message to the computing power management function to request the computing power management function to perform the processing of releasing the computing power resource, which are collectively referred to as case two below.

[0086] In the embodiments of the present application, the SMF or the computing power management function in the network obtains a message for requesting to release one or both of the communication resource and the computing power resource in the computing session, and performs the corresponding resource release processing, thereby realizing the release of the communication resource and the computing power resource by the network.

[0087] Specifically, the above step 202 refers to, in the above case one, after the SMF obtains the first message, the SMF sends a second message to the PCF to request to delete the communication management policy.
