[0003] In the 6G era, the network is no longer a simple communication network, but a deep integration network of computing, data, AI and communication, which provides diversified information services for users. The traditional mobile communication network provides services such as voice and data, which are basic services of universal nature, and only provides a transmission channel for users without any data processing.

[0004] Currently, in the related network architecture, the session management function and the data-related function are completely separated for the session establishment process, each of which is responsible for the corresponding service, and there is no interaction between the session management function and the data-related function when executing the data service. Or, the control and arrangement management function of the data plane are integrated with the session management function. If other service types of network functions, such as AI and computing, are integrated in this way, it will cause the network element to be relatively large, increase the complexity of the network function, and be not conducive to the network customization according to the needs of multiple application scenarios.

[0178] In the present disclosure, the term “and / or” describes an association relationship of associated objects, which means that there can be three relationships, for example, A and / or B can mean that there are three cases of A alone, A and B together, and B alone. The character “ / ” generally represents an “or” relationship between the associated objects before and after it.

[0179] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present disclosure.

[0180] In order to clearly understand the technical solutions of the present disclosure, first, the solutions of the related art will be described in detail.

[0181] Currently, in the related network architecture, for the session establishment process, the session management function and the data-related function are completely separated, each of which is responsible for the corresponding service, and there is no interaction between the session management function and the data-related function when performing data services. Alternatively, the control and arrangement management function of the data plane are integrated with the session management function. If other business types of network functions, such as AI, computing, etc., are integrated in this way, it will cause the network element to be relatively large, increase the complexity of the network function, and be not conducive to the network customization according to the needs of multiple application scenarios. In addition, the introduction of new functions will affect the existing services, and at the same time, it does not meet the plug-and-play characteristics of the 6G network.

[0182] Therefore, the session establishment process in the related art cannot be applied to the user's demand for various services in the 6G network.

[0183] Therefore, based on the above research, the business session establishment method, device and readable storage medium provided by the present disclosure are proposed. In the present disclosure, the UE sends a session establishment message to the network, receives a session acceptance response message sent by the network, and realizes business session establishment. The session establishment message carries the business type (such as AI, perception, data, computing, etc.) requested by the UE, the business session ID, the session management information, etc. Therefore, different business session establishments can be realized based on different business types, and can be applied to the user's demand for AI, perception, data, computing, etc. in the 6G network scenario.

[0184] Among them, the method and the device are based on the same application concept. Since the principles of solving problems are similar, the implementation of the device and the method can be mutually referred to, and the repeated parts will not be described again.

[0185] Embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0186] Referring to FIG. 1, FIG. 1 is a flowchart of a business session establishment method provided by an embodiment of the present disclosure. The execution subject of the business session establishment method provided by the present embodiment is a UE, and the business session establishment method will be described in detail below.

[0187] The business session establishment method provided by the present embodiment includes the following steps:

[0188] Step 101: sending a session establishment message, wherein the session establishment message includes: UE demand type, business session ID, and session management information, and the UE demand type is used to indicate the business type requested by the UE;

[0189] Step 102: receiving a session acceptance response message.

[0190] In the embodiments of the present disclosure, the UE realizes service session establishment by sending a session establishment message to the network and receiving a session acceptance response message sent by the network. The session establishment message carries UE demand type, service session ID, session management information, etc. The UE demand type is used to indicate the service type (such as AI, perception, data, computing, etc. New services) requested by the UE. Based on different service types, different service session establishments are realized, which can be applied to the demand of users for AI, perception, data, computing, etc. New services in the 6G network scenario.

[0191] The UE sends a session establishment message to the network (such as a first network function or an access network device in the core network). The first network function or the access network device receives the session establishment message and interprets the UE demand type and the service session ID in the session establishment message. The session management information is encapsulated in a container. For example, a message content such as session management information is encapsulated in the container in the "session establishment message". When the receiving end (such as the first network function or the access network device) receives the "session establishment message", it does not interpret the message content (such as the session management information) encapsulated in the container, but directly and transparently sends the message content encapsulated in the container to the next node (such as a second network function or a third network function), which reads the message content encapsulated in the container.

[0192] For the 6G network, a service establishment process (referred to as service session establishment process) for users to obtain new services such as AI, computing, data, and perception is designed in combination with the related session establishment process. In the service session establishment process, the UE sends the following messages to the network: UE demand type (computing power, AI, perception, data, voice), [optionally, DNN] (referring to traditional session establishment), session ID (herein, service session ID, which will not be described below), N1 SM container (encapsulating session management information). The session management information includes session ID, Requested demand Type, [optionally, requested session SSC mode] (related to demand), and demand information.

[0193] In the service session management function selection process, when there is a demand for new services, the support of the service session management function for the new service capability needs to be considered.

[0194] Optionally, the session management information includes the service session ID, the UE requested service type, and demand information.

[0195] The demand information includes parameters of the requested service type.

[0196] Optionally, when the UE requirement type is a traditional voice and data service, the session establishment message further comprises the following: information of at least one network slice, a data network name (DNN) requested by the UE.

[0197] When the UE requirement type is a new service other than the traditional voice and data service, the session establishment message further comprises or does not comprise at least one of the following: information of at least one network slice, a DNN requested by the UE, the new service comprising at least one of the following: artificial intelligence (AI), perception, data, and calculation.

[0198] For the new service, the session establishment message sent by the UE can carry the information of at least one network slice and / or the DNN requested by the UE, or can not carry the information of at least one network slice and / or the DNN requested by the UE, both of which can realize establishment of the new service.

[0199] Optionally, the sending of the session establishment message comprises the following:

[0200] The session establishment message is sent to a core network device or an access network device.

[0201] Optionally, the receiving of the session acceptance response message comprises the following:

[0202] The session acceptance response message is received from a core network device or an access network device.

[0203] In the embodiments of the present disclosure, the UE initiates a service session establishment message (hereinafter referred to as a session establishment message) to the network (an access network and a core network), and the service session establishment message contains: a UE requirement type, (optionally, information of at least one network slice, such as Single Network Slice Selection Assistance Information (S-NSSAI) hereinafter referred to as S-NSSAI (s)), (optionally, a data network name (DNN) requested by the UE, that is, UE Requested DNN), a service session ID, an N1 SM container (encapsulating session management information), and the like, wherein the session management information includes a service session ID, a Requested requirement Type (that is, a requested service type, hereinafter referred to as a UE requested service type), (optionally, a requested session service continuity mode (SSC mode)), requirement information. Based on the above information, the service session establishment is performed. Based on different service types, different service session establishments are further implemented, which can be suitable for the demand of users for AI, perception, data, calculation and other new services in the 6G network scenario.

[0204] In combination with FIG. 2, FIG. 2 shows a network architecture diagram. In the core network (English: Core Network, CN for short), the following functions can be included: subscription data management function, AI function, data function, sensing function, policy control function, network storage function, computing function, user plane function, access mobility management function, service session management function, etc. The AI function represents the control, management, and execution functions of network intelligence. The control, management, and execution functions of AI; the data function represents the control, management, and execution functions of data; the computing function represents the arrangement, management, and execution functions of computing resources; the access mobility management function (such as Access and Mobility management Function, AMF for short) includes the access mobility management of traditional services, and can also include the access mobility management of new services such as data, sensing, computing, and AI; the service session management function (such as Session Management Function, SMF for short) includes the session management of traditional service connections, and can also include the connection management of new services such as data, sensing, computing, and AI; the policy control function includes the policy control management of traditional services, and can also include the policy control management of new services such as data, sensing, computing, and AI; the subscription data management includes the user subscription data management of traditional service connections, and can also include the user subscription data management of new services such as data, sensing, computing, and AI; the network storage function includes the registration, storage, discovery, and other services of traditional network functions, and also includes the registration, storage, discovery, and other services of enhanced traditional network functions and new functions such as data, computing, sensing, and AI; and the user plane function supports data forwarding and transmission in different dimensions such as intelligence, sensing, computing, and data.

[0205] Here, the service not only includes basic services such as voice and data, but also can include future new services such as intelligence, sensing, computing, and data.

[0206] The above network functions will register and report relevant information to the network storage function, including the support of new information elements such as computing, data, AI, and security.

[0207] Specifically, for a 6G network, a service establishment process for a user to obtain a new service is designed.

[0208] 1. UE initiates service session establishment message to network (access network and core network): UE requirement type, [optionally, S-NSSAI(s)], [optionally, UE Requested DNN], service session ID, N1 SM container (encapsulating session management information), etc. information, wherein the N1 SM container includes service session ID, Requested requirement Type, [optionally, Requested session SSC mode], requirement information.

[0209] Based on the above information, the service session establishment process is performed, and the following two methods can be used:

[0210] Method 1:

[0211] 2.1 The first network function (such as access mobility management function) performs AI selection based on user requirement type, and sends the session management information in the service session establishment request message (herein referred to as session establishment message) to the selected second network function (such as service session management function);

[0212] 3.1 For new services, the second network function performs AI selection, and sends the service establishment request to the selected network function of the new service, and carries the service requirement information and other information.

[0213] 4.1 AI performs service policy generation based on the obtained subscription data and policy information.

[0214] 5 The second network function performs user plane connection establishment based on the service policy sent by AI.

[0215] Method 2:

[0216] 2.2 The first network function (such as access mobility management function) performs AI selection based on user requirement type, and sends AI new service establishment request (which contains session management information) to the selected AI.

[0217] 3.2 AI performs service policy generation based on the obtained subscription data and policy information, and performs selection of the second network function (such as service session management function) at the same time.

[0218] 3.3 The selected second network function performs user plane connection establishment based on the service policy.

[0219] Among them, for new services, the selection of the second network function and the third network function (such as AI) needs to consider the service type and requirement information.

[0220] For example, embodiment one (service session establishment process, user service judgment by service session management function)

[0221] Referring to FIG. 3, FIG. 3 is an interaction diagram of a service session establishment method provided by the embodiment of the present disclosure, and the steps of the service session establishment method include:

[0222] Step 1: UE initiates a service session establishment message (UE to CN: NAS message) to the access mobility management function: NAS Message (UE requirement type, [optionally, S-NSSAI(s)], [optionally, UE Requested DNN], service session ID, N1 SM container, and the like). The N1 SM container includes the service session ID, Requested requirement type, [optionally, requested session SSC mode], and requirement information.

[0223] The UE requirement type refers to the service type requested this time, such as AI type, perception, data (service), computing power, traditional voice and data service, and the like; the requirement information refers to the specific parameters of the requested service type, such as data type, data location, data acquisition frequency, data accuracy, data real-time performance, and the like for data service; computing resource type, required computing power size, service type, time length, and the like for computing power service; data type, data size, data dimension, AI inference result requirement, and the like for AI service. When only the requirement type is traditional voice and data service, [S-NSSAI(s)], [UE Requested DNN], and [requested session SSC mode] need to be carried, and other types of services can not carry the parameters (or can carry the parameters).

[0224] Step 2: The access mobility management function performs service session management function selection, which will be described in the following embodiment four.

[0225] Step 3: The service session management function receives the service session creation request from the access mobility management function, judges the requested service type based on the parameters carried in the request message to obtain the corresponding network function. If it is traditional voice and data service, 4A is executed, otherwise 4B or 4C is executed. 4A is not expanded, and can be referred to the 5G session establishment process.

[0226] The following steps are for the 4B process:

[0227] Step 4B: The service session management function performs the selection of AI and the like (i.e., step 4a), and sends a service establishment request to the network function of the new service selected (i.e., step 4b), carrying the service session ID, requirement information, and the like.

[0228] Steps 5-7: After receiving the request, the network function of the new service (here, the third network function) performs subscription data acquisition and network policy acquisition, and determines the service policy of the new service. The network function of the new service sends a response message to the service session management function, carrying the service policy of the new service, or also carrying the selected user plane function. The execution of the user plane function selection can be performed by the network function of the new service, or by the service session management function. Here, the service session management function and the AI and the like can respectively acquire corresponding subscription data and policies, or one of them can acquire all the subscription data of the user.

[0229] Among them, step 5: the network function of the new service acquires subscription data from the subscription data management function; step 6: the network function of the new service acquires network policy (here, service policy) from the policy control function; optionally, the network function of the new service selects the user plane. Step 7a: the network function of the new service sends an AI and the like new service establishment response to the service session management function; optionally, step 7b: the service session management function acquires subscription data from the subscription data management function; optionally, step 7c: the service session management function acquires network policy from the policy control function. Optionally, the service session management function selects the user plane.

[0230] Step 8: Based on the response message, the service session management function generates user plane forwarding rules, service processing rules, and the like based on the service policy of the new service, and can also need to select the user plane function (based on the result of step 8, if the user plane function has been selected in step 8, the operation is ignored.).

[0231] Step 9: The service session management function sends a service session acceptance response message to the access mobility management function, and the access mobility management function sends a service session acceptance response message to the UE.

[0232] The following steps are for the 4C process:

[0233] Step 4C: The service session management function acquires subscription data from the subscription data management function (i.e., step 4);

[0234] Step 5: The service session management function acquires network policy from the policy control function;

[0235] Step 6: After receiving the request, the network function of the new service (here, the third network function) performs subscription data acquisition and network policy acquisition to determine the service policy of the new service. The network function of the new service sends a response message to the service session management function, carrying information including the service policy of the new service, or also including the selected user plane function. The execution of the user plane function selection can be the network function of the new service, or the service session management function. Here, the service session management and AI functions can be used to acquire corresponding subscription data and policies, respectively, or one of them can acquire all relevant subscription data of the user.

[0236] Step 6a: The service session management function sends a service establishment request to the selected network function of the new service; optionally, step 6b: the network function of the new service acquires subscription data from the subscription data management function; step 6c: the network function of the new service acquires network policy from the policy control function. The network function of the new service generates a service policy; optionally, the network function of the new service performs user plane selection.

[0237] Step 7: The network function of the new service sends an AI new service establishment response to the service session management function.

[0238] Optionally, the service session management function performs user plane selection.

[0239] Step 8: Based on the response message, the service session management function generates user plane forwarding rules, service processing rules, etc. based on the service policy of the new service, and can also perform user plane function selection (based on the result of step 8, if the user plane function has been selected in step 8, the operation is ignored.).

[0240] Step 9: The service session management function sends a service session acceptance response message to the access mobility management function, and the access mobility management function sends a service session acceptance response message to the UE.

[0241] For example, embodiment two (service session establishment process, service judgment by the access mobility management function)

[0242] Referring to FIG. 4, FIG. 4 is an interaction diagram of a service session establishment method provided by the embodiment of the disclosure.

[0243] Different from embodiment one, the access mobility management function determines the type of service of the UE based on the NAS message sent by the UE, and if it is a new service, the service session establishment request is sent to the AI function (i.e., the network function of the new service (here, the third network function)). The AI function performs service session management function selection.

[0244] The steps of the service session establishment method include:

[0245] Step 1: UE initiates a service session establishment message to the access mobility management function (UE to CN: NAS message): NAS Message (UE requirement type, [optionally, S-NSSAI(s)] [optionally, UE Requested DNN], service session ID, N1 SM container, etc. information). Wherein the N1 SM container includes service session ID, Requested requirement type, [optionally, requested session SSC mode], requirement information.

[0246] Wherein, the UE requirement type refers to the type of service requested this time, such as AI type, perception, data (service), computing power, traditional voice and data service, etc.; the requirement information refers to the specific parameters of the requested service type, such as for data service, it may contain data type, data location, data acquisition frequency, data accuracy, data real-time performance, etc. information; for computing power service, it may contain computing power resource type, demand computing power size, service type, time length, etc. information; for AI service, it may contain data type, data size, data dimension, AI inference result requirement, etc. information. When only the requirement type is traditional voice and data service, [S-NSSAI(s)], [UE Requested DNN], [requested session SSC mode] need to be carried, and other types of services can not carry this parameter (also can carry this parameter).

[0247] Step 2: The access mobility management function performs AI function selection. The access mobility management function judges the type of service requested based on the parameters carried in the request message to obtain the corresponding network function. If it is traditional voice and data service, execute 3a, otherwise execute 3b and 4A process or execute 3b and 4B. Wherein 3a is not expanded, which can be referred to the session establishment process of 5G.

[0248] Step 3b: The access mobility management function sends a service establishment request to the selected network function of new type service, and carries service session ID, requirement information, etc.

[0249] The following steps are for the process of 4A:

[0250] Step 4-7: After receiving the request, the network function of the new service performs subscription data acquisition and network policy acquisition to determine the service policy of the new service. The network function of the new service sends a response message to the service session management function, carrying information including the service policy of the new service, or also including the selected user plane function. The execution of the user plane function selection can be the network function of the new service, or the service session management function. Here, the service session management and AI functions can be required to acquire corresponding subscription data and policies respectively, or one of them can acquire all relevant subscription data of the user.

[0251] Step 4: The network function of the new service acquires subscription data from the subscription data management function; Step 5: The network function of the new service acquires network policy (here, service policy) from the policy control function; optionally, the network function of the new service performs user plane selection. Step 6: The network function of the new service performs service session management function selection. Step 7a: The network function of the new service sends an AI and the like new service establishment response to the service session management function; optionally, step 7b: The service session management function acquires subscription data from the subscription data management function; optionally, step 7c: The service session management function acquires network policy from the policy control function. Optionally, the service session management function performs user plane selection.

[0252] Step 8: The service session management function establishes a connection with the selected user plane.

[0253] Step 9: The service session management function sends a service session creation response message to the network function of the new service.

[0254] Step 10: The network function of the new service sends a service session acceptance response message to the access mobility management function, and the access mobility management function sends a service session acceptance response message to the UE.

[0255] The following steps are for the 4B process:

[0256] Step 4: The network function of the new service performs service session management function selection;

[0257] Step 5-7: The network function of the new service performs subscription data acquisition and network policy acquisition to determine the service policy of the new service. The network function of the new service sends a response message to the service session management function, carrying information including the service policy of the new service, or also including the selected user plane function. The execution of the user plane function selection can be the network function of the new service, or the service session management function. Here, the service session management and AI functions can be required to acquire corresponding subscription data and policies respectively, or one of them can acquire all relevant subscription data of the user.

[0258] In the method, in step 5, the network function of the new service acquires subscription data from a subscription data management function; and in step 6, the network function of the new service acquires a network policy from a policy control function. The network function of the new service generates a service service policy; and optionally, the network function of the new service performs user plane selection.

[0259] In step 7a, the network function of the new service (here, a third network function) sends a service session creation request to a service session management function.

[0260] Optionally, in step 7b, the selected service session management function acquires subscription data and acquires a network policy. Optionally, in step 7c, the selected service session management function acquires a network policy from a policy control function. Optionally, the selected service session management function performs user plane selection.

[0261] In step 8, the service session management function establishes a connection with the selected user plane.

[0262] In step 9, the service session management function sends a service session creation response message to the network function of the new service.

[0263] In step 10, the network function of the new service sends a service session acceptance response message to an access mobility management function, and the access mobility management function sends a service session acceptance response message to the UE.

[0264] For example, in a radio access network (RAN) service scenario, the RAN can perform operations performed by an access mobility management function.

[0265] As shown in FIG. 5, FIG. 5 is an interaction diagram three of a service session establishment method provided by an embodiment of the present disclosure.

[0266] The service session establishment method includes the following steps:

[0267] In step 1, the UE initiates a service session establishment message (UE to CN: NAS message) to the access mobility management function: NAS Message (UE requirement type, [optional S-NSSAI], [optional UE Requested DNN], service session ID, N1 SM container, and the like). The N1 SM container includes a service session ID, a Requested requirement type, [optional Requested session SSC mode], and requirement information.

[0268] Wherein, the UE demand type refers to the service type of this request, such as AI type, perception, data (service), computing power, traditional voice and data service, etc.; the demand information refers to the specific parameters of the requested service type, such as for data service, it may contain data type, data location, data acquisition frequency, data accuracy, data real-time performance, etc. For computing power service, it may contain computing power resource type, demand computing power size, service type, time length, etc. For AI service, it may contain data type, data size, data dimension, AI inference result requirement, etc. When only the demand type is traditional voice and data service, [S-NSSAI (s)], [UE Requested DNN], [requested session SSC mode] need to be carried, and other types of services can not carry this parameter (or can carry this parameter).

[0269] Step 2: Access the mobility management function for AI and other function selection. The access mobility management function judges the requested service type based on the parameters carried in the request message to obtain the corresponding network function. If it is traditional voice and data service, execute 3a, otherwise execute 3b, 4 and 5A process or execute 3b, 4 and 5B. Wherein 3a is not expanded, which can be referred to 5G session establishment process.

[0270] Step 3b: The access mobility management function sends a service establishment request to the selected network function of new service, and carries the service session ID, demand information and other information.

[0271] Step 4: The network function of new service performs service session management function selection.

[0272] The following steps are for 5A process:

[0273] Steps 5-7: The network function of new service performs subscription data acquisition and network policy acquisition to determine the service policy of new service. The network function of new service sends a response message to the service session management function, which carries the service policy of new service, or also includes the selected user plane function. The execution of user plane function selection may be the network function of new service, or the service session management function. Here, the service session management and AI and other functions may obtain the corresponding subscription data and policy respectively, or one of them may obtain all the related subscription data of the user.

[0274] Step 5: The network function of the new service acquires subscription data from the subscription data management function; Step 6: The network function of the new service acquires network policy (here, service service policy) from the policy control function; optionally, the network function of the new service performs user plane selection. Step 7: The network function of the new service sends a service session creation request to the service session management function; optionally, the service session management function performs user plane selection.

[0275] Step 8: The service session management function establishes connection with the selected user plane.

[0276] Step 9: The service session management function sends a service session creation response message to the network function of the new service.

[0277] Step 10: The network function of the new service sends a service session acceptance response message to the access mobility management function, and the access mobility management function sends a service session acceptance response message to the UE.

[0278] The following steps are for the 5B process:

[0279] Step 5: The network function of the new service sends a service session creation request to the service session management function.

[0280] Step 6: The service session management function acquires subscription data from the subscription data management function;

[0281] Step 7: The service session management function acquires network policy from the policy control function;

[0282] Optionally, the service session management function performs user plane selection.

[0283] Step 8: The service session management function establishes connection with the selected user plane.

[0284] Step 9: The service session management function sends a service session creation response message to the network function of the new service.

[0285] Step 10: The network function of the new service sends a service session acceptance response message to the access mobility management function, and the access mobility management function sends a service session acceptance response message to the UE.

[0286] In the RAN service scenario, the RAN can select AI and other functions. In this embodiment, the RAN can parse the UE service requirement information, which includes: UE requirement type, [optionally, S-NSSAI (s)], [optionally, UE Requested DNN], service session ID, N1 SM container and other information. The implementation process of this embodiment can also be seen in FIG. 3 and FIG. 4 (replace the access mobility management function with the RAN), which will not be described here.

[0287] Example 4 (selection of service session management function)

[0288] In the processing of new services, the selection of the service session management function needs to consider the new service requirement information requested by the UE, that is, the AI and other new service identification information and the location of the UE need to be carried in the network function discovery request information sent to the network storage function.

[0289] Referring to FIG. 6, FIG. 6 is an interaction diagram four of the service session establishment method provided by the embodiment of the present disclosure.

[0290] The steps of the service session establishment method include:

[0291] Step 0: The service session management function item network storage function sends a network function (English: Network Function, abbreviated as: NF) registration request (the NF profile includes the support capability for new services).

[0292] Step A: Implementation process for the access mobility management function

[0293] Step 1: The access mobility management function sends a service session management function discovery request (carrying AI and other new service identification information) to the network storage function;

[0294] Step 2: The network storage function sends a service session management function discovery response to the access mobility management function.

[0295] Step B: Implementation process for AI and other functions

[0296] Step 1: AI and other functions send a service session management function discovery request (carrying AI and other new service identification information) to the network storage function;

[0297] Step 2: The network storage function sends a service session management function discovery response to AI and other functions.

[0298] Example 5 (service session modification / release process)

[0299] Due to the introduction of new services, the trigger of service session modification and release will also be expanded from the original network function to AI and other functions. The reasons for modification and release may be due to changes in QoS parameters of new services, changes in service providers, completion of services, etc.

[0300] Therefore, in the present disclosure, the UE achieves service session establishment by sending a session establishment message to the network and receiving a session acceptance response message sent by the network. The session establishment message carries the service type (such as AI, perception, data, calculation, etc.) requested by the UE, service session ID, session management information, etc., so that different service session establishments can be achieved based on different service types, and can be suitable for the demand of users for AI, perception, data, calculation, etc. in the 6G network scenario.
