[0121] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0122] The existing service establishment process is based on AMF forwarding UE and RAN side signaling to related CN network elements. In the future, the network will gradually realize end-to-end service. The industry is discussing the service-oriented RAN control plane and the N2 interface, which is the interface between RAN and AMF. How will the RAN and CN network architecture evolve? Figure 1 shown.

[0123] Based on the traditional method, direct interaction and mutual calling of RAN and CN services can be achieved. However, it may cause the complexity of cross-domain service calling, especially with the increase of services in the future network, this mutual calling relationship will become more complicated; and based on the existing solution, it is impossible to establish high-quality and highly flexible service links based on user preferences, service characteristics and network real-time resources, and give full play to the service advantages. Therefore, it is necessary to optimize the existing service establishment process.

[0124] The embodiment of the present application proposes a service establishment method based on service policy. The proposed RAN network storage function realizes functions such as registration of RAN side services, cross-domain discovery and invocation of core network CN services, and service policy issuance.

[0125] The following, in conjunction with the accompanying drawings, describes in detail the service registration and discovery method, business policy negotiation method and business establishment method provided in the embodiments of the present application through specific embodiments and their application scenarios.

[0126] See also Figure 2 , Figure 2 is a flow chart of a service establishment method performed by a UE provided in an embodiment of the present application, such as Figure 2 As shown, the following steps are included:

[0127] Step 201: Send a service establishment request to a radio access network RAN ​​network element, wherein the service establishment request includes a UE ID and a requested service type, and the RAN network element is a RAN network function NF or a RAN network storage function. In the case where the RAN network element is a RAN network function (NF), the service establishment request also includes a service policy identifier (ID) selected by the UE.

[0128] In the embodiment of the present application, in order to assist the RAN side function to quickly call the core network service across domains, simplify the signaling interaction between NFs, and realize the rapid establishment of services, a new RAN side network element is proposed, that is, a RAN network storage function can be developed, or it can also be called a RAN network storage library function or a RAN service management function (such as a RAN synchronous equipment management function (Synchronous Equipment Management FunctionSeMF)), which is used to assist the RAN side NF to realize service registration, as well as cross-domain discovery, service policy negotiation and calling functions with the core network CN service. The RAN network storage function is a network side network element.

[0129] It should be noted that before the formal service establishment process is carried out, the RAN network storage function can pre-register, discover and negotiate service policies with the CN NF and RAN NF, and send the service request configuration to the UE, so that the RAN network storage function obtains the CN NF information that supports the service policy negotiation function, thereby initiating service policy requests to these CN NFs, obtaining service policy related information, and broadcasting service policy related information to the relevant RAN NFs, thereby establishing the association between the CN NF, RAN NF and the service policy. In addition, the relevant service policy information and reporting configuration information can also be sent to the UE, so that the UE can select the service policy according to the service needs and initiate the service establishment process to the RAN side, or directly initiate the service establishment process to the RAN side, and the RAN side assists the UE in selecting the appropriate service policy according to the network environment. In this embodiment, it is assumed that before initiating the service establishment request, the RAN network storage function has performed the above process with the CN NF, RAN NF and UE.

[0130] This embodiment provides a fast service establishment process based on service policy. When there is a demand for service use, the UE can send a service establishment request to the relevant network element on the RAN side, and the service establishment request at least includes the UE ID, i.e., the identifier of the UE and the service type, which is used to indicate the requested UE and service type. The service type may be voice service, data service, interactive service, collection service, etc. When the UE needs to request a data service, the data service type is carried in the service establishment request. In specific implementation, the service establishment request can be sent via a Radio Resource Control (RRC) message. For example, the UE can send an RRC establishment request to the RAN network element, and the RRC establishment request carries the service request ID, UE ID and the requested service type. The service request ID is used to indicate the request to establish the service.

[0131] In actual applications, there can be two different service establishment scenarios. Scenario 1 is that the UE independently selects a service strategy and directly interacts with the RAN NF associated with the selected service strategy. This scenario is suitable for latency-sensitive services, and the UE directly interacts with the associated RANNF for parallel processing.

[0132] In this scenario, the UE can independently select a service policy based on service requirements. Specifically, the UE can select a suitable service policy based on the service policy information pre-issued to it by the RAN network storage function and the service type requested by itself, and determine the RAN NF associated with the service policy, thereby directly initiating a service establishment request to the RAN NF, and carrying at least the UE ID, service type and selected service policy ID in the request to inform the RAN NF of the service type requested by the UE and the selected service policy, so that the RAN NF responds to its request and uses the corresponding service policy to provide the UE with service services of the corresponding service type.

[0133] Scenario 2 is that the RAN network storage function assists the UE in selecting service policies. The RAN network storage function can flexibly select service policies for the UE according to the network environment and instruct the relevant RAN NF to provide services. This scenario is suitable for services with high reliability requirements.

[0134] In this scenario, the UE can initiate a service establishment request to the RAN network storage function according to service requirements, and carry at least the UE ID and service type in the request to inform the RAN network storage function of the service type requested by the UE, so that the RAN network storage function selects a service policy suitable for its service type for the UE, and instructs the associated RAN NF to use the corresponding service policy to provide the UE with service services of the corresponding service type.

[0135] After receiving the service establishment request sent by the UE, the RAN network element can establish and provide a service of the corresponding service type for the UE according to information such as the service type carried in the request.

[0136] Specifically, in the case where the UE sends a service establishment request carrying at least the requested service type and the selected service policy ID to the RAN NF, that is, corresponding to scenario one, the RAN NF can determine the CN NF associated with the service policy ID based on the service policy related information broadcasted to it by the RAN network storage function in the service policy negotiation process according to the service policy ID, and thus send a service establishment request carrying at least the UE ID and the service policy ID to the CN NF; the CN NF then uses the service policy corresponding to the service policy ID to establish a service service of the corresponding service type for the UE based on the UE ID and the service policy ID carried in the service establishment request; and the RAN NF can cooperate with the CN NF to provide the UE with a service service of the corresponding service type.

[0137] In the case where the UE sends a service establishment request carrying at least the requested service type to the RAN network storage function, that is, corresponding to scenario 2, the RAN network storage function may select a suitable service policy for the UE according to the service type, and determine the RAN NF associated with the service policy ID selected for the UE based on the RAN NF information associated with each service policy ID obtained by the RAN network storage function in the service policy negotiation process, thereby sending a service establishment indication to the RAN NF, and the indication carries at least the UE ID and the service policy ID, which is used to indicate that the RAN NF needs to use the service policy ID to establish a service service for the UE; the RAN NF determines the CN NF associated with the service policy ID based on the service establishment indication and the service policy related information broadcasted to it by the RAN network storage function in the service policy negotiation process, thereby sending a service establishment request carrying at least the UE ID and the service policy ID to the CN NF; the CN NF uses the service policy corresponding to the service policy ID to establish a service service of the corresponding service type for the UE based on the UE ID and the service policy ID carried in the service establishment request; the RAN NF may cooperate with the CN The NF provides business services of the corresponding business type for the UE.

[0138] Optionally, before step 201, the method further includes:

[0139] Receiving a service request configuration sent by the RAN network storage function, wherein the service request configuration includes service policy information and reporting configuration information, the service policy information includes at least one service policy ID to be selected and a service type and service policy applicable condition associated with each service policy ID to be selected, and the reporting configuration information includes a device ID and a service type;

[0140] The step 201 comprises:

[0141] Selecting a service policy ID from the at least one service policy ID to be selected, and sending a first service establishment request to the RAN NF associated with the selected service policy ID, wherein the first service establishment request includes a UE ID, a requested service type, and the selected service policy ID;

[0142] Alternatively, a second service establishment request is sent to the RAN network storage function, wherein the second service establishment request includes the UE ID and the requested service type.

[0143] In one implementation, the RAN network storage function may issue a service establishment configuration between the base station and the UE based on the service policy. That is, the RAN network storage function may configure the service request for the UE, inform the UE of the optional service policy information and the relevant information that needs to be reported in the service establishment process, so that when the UE has a service use demand, it can select a service policy suitable for its service according to the service policy information configured by the network, and send a service establishment request carrying the corresponding information to the associated RAN NF according to the relevant information that needs to be reported by the network configuration, or directly send a service establishment request carrying the corresponding information to the RAN network storage function according to the relevant information that needs to be reported by the network configuration.

[0144] Specifically, the RAN network storage function can send a service request configuration to the UE, which can be sent to the UE through a non-access layer (NAS) or an RRC message, and the service request configuration includes at least service policy information and reporting information configuration; wherein the service policy information is optional service policy information sent by the network to the UE, including at least one optional service policy ID, an associated service type, and a service policy applicable condition; the reporting configuration information is the relevant information that the UE needs to report when establishing a service, including at least a device ID and a requested service type.

[0145] The associated service type refers to the service type associated with each optional service policy ID; and the RAN network storage function can issue multiple service policies for the same service type.

[0146] The service policy applicability conditions refer to the conditions under which each optional service policy ID is available, for example, the UE link quality reaches the configured threshold, the UE computing power processing capability is higher than the configured threshold, the security policy supported by the UE meets the configured level, etc.; or the UE receives a service type indication broadcast by the base station that is applicable to the service policy.

[0147] The above business request configuration process can be found in Figure 5 The service request configuration interaction process between the UE and the RAN network storage function.

[0148] After receiving the service request configuration, the UE can choose to independently select a service policy or have the network assist it in selecting a service policy according to the service scenario that actually needs to be established, and initiate a service establishment request to the corresponding RAN side network element according to the service request configuration, carrying the relevant information that the network indicates needs to be reported in the request.

[0149] Specifically, in scenario 1, the UE can select a service policy ID from at least one service policy ID configured in the network according to service usage requirements, and send a first service establishment request to the RAN NF associated with the selected service policy ID, in which the request carries at least the UE ID, the requested service type and the selected service policy ID; the RAN NF responds accordingly based on the first service establishment request, and uses the service policy selected by the UE in combination with the associated CN NF to provide the UE with service services of the corresponding service type.

[0150] In scenario 2, the UE can directly send a second service establishment request to the RAN network storage function according to the service usage requirements, and the request carries at least the UE ID and the requested service type. The RAN network storage function responds accordingly to the second service establishment request, selects a suitable service policy ID for the UE, and instructs the associated RAN NF and CN NF to use the service policy selected by the UE to provide the UE with a service of the corresponding service type.

[0151] In this implementation, the network configures the UE's optional service policy information and the reporting information during service establishment, so that the UE can obtain optional service policy information, can independently select service policies, and can also initiate service establishment requests according to its configuration specifications, ensuring that the service is quickly and successfully established.

[0152] Optionally, the service policy information further includes at least one of a service policy priority, associated RAN NF information, associated CNNF information, a service capability of the service policy, a geographical scope of application of the service policy, and a time scope of application of the service policy.

[0153] That is, in one implementation, the RAN network storage function may also include service policy priority, associated RAN NF information, associated CN NF information, service capability of the service policy, geographical scope of application of the service policy, time scope, etc. in the service policy information configured for the UE.

[0154] The service policy priority refers to the priority between different service policies, and can guide the UE to prioritize multiple service policies when there are multiple service policies to choose from or multiple services are established.

[0155] The associated RAN NF information may include information of a single RAN NF associated with a service policy, or may include information of a RAN NF set associated with a service policy, which refers to the RAN NF or RAN NF set information that needs to provide corresponding services when establishing a certain service, including but not limited to NF ID, NF IP address, NF type, etc.; when the network sends the RANNF / NF set information associated with the service policy to the UE, the UE can directly initiate a service request to the corresponding NF.

[0156] The associated CN NF information may include information of a single CN NF associated with the service policy, or may include information of a CN NF set associated with the service policy, that is, information of the CN NF or CN NF set that needs to provide corresponding services when establishing a certain service, including but not limited to NF ID, NF IP address, NF type, etc.

[0157] The service policy service capability refers to the service capability level corresponding to the service policy; different service policies can be associated with different RAN NFs, CN NFs and their service capabilities, so the service link quality and service capabilities provided by different service policies may be different. The UE can select the service policy based on the service capability level matched by the service policy, combined with its own capabilities and preferences.

[0158] The applicable geographical scope and time scope of the business policy may refer to that the business policy has available geographical scope restrictions and time scope restrictions, such as the business policy is available in certain geographical locations and in certain time periods.

[0159] In this implementation, by configuring more comprehensive service policy information for the UE, the UE can be better guided to select a service policy and quickly initiate a service establishment request.

[0160] Optionally, the reporting configuration information further includes at least one of a selected service policy ID, a requested service capability, link quality information, and device capability information.

[0161] That is, in one implementation manner, the RAN network storage function may also include the selected service policy ID, requested service capabilities, air interface link quality information, device capability information, etc. in the reporting configuration information sent to the UE.

[0162] The selected service policy ID refers to the service policy ID selected by the UE.

[0163] The service capability requested by the UE refers to the demand for network service capability reported by the UE. For example, a RAN-side positioning service can be called when a service request is made, and the UE can carry the positioning accuracy level in the service request message; or the UE can select the service capability based on the service policy issued by the network.

[0164] The air interface link quality information, the device capability information, etc. can assist the network in selecting a service strategy that is suitable for the UE and is beneficial to optimizing resources on the RAN side.

[0165] In this implementation manner, by instructing the UE to report more specific service establishment related information, it is beneficial for the network to perform more targeted service policy configuration on the UE, thereby ensuring the service quality of the UE.

[0166] Optionally, the service establishment request also includes at least one of requested service capability, link quality information and UE capability information.

[0167] That is, in one implementation, when initiating service establishment, the UE may also carry the requested service capability, air interface link quality information, UE capability information, etc. in the service establishment request to indicate the network's required service capability, current network status, own capability, etc. In specific implementation, the UE may carry the relevant information indicated by the network to be reported when sending a service establishment request to the network, according to the specific relevant information to be reported indicated in the reporting configuration information sent by the network.

[0168] In this implementation, by reporting more specific relevant information for service establishment in the service establishment request, the network can be assisted in selecting a service strategy that is suitable for the UE and is conducive to resource optimization on the RAN side, thereby ensuring the service quality of the UE.

[0169] Optionally, after step 201, the method further includes:

[0170] Receive a service establishment request response sent by the RAN network element, wherein the service establishment request response includes the UE ID and the service type, and when the RAN network element is a RAN network storage function, the service establishment request response also includes a service policy ID indicating the UE selection.

[0171] That is, the RAN network element can establish and provide a service of the corresponding service type for the UE according to the service type and other information carried in the service establishment request of the UE, and then return a service establishment request response to the UE, and the response can carry at least the UE ID and the service type, to indicate that the service of the service type has been successfully established for the UE.

[0172] Specifically, in the case where the UE sends a service establishment request carrying at least the requested service type and the selected service policy ID to the RAN NF, that is, corresponding to scenario one, the RAN NF can determine the CN NF associated with the service policy ID based on the service policy related information broadcasted to it by the RAN network storage function in the service policy negotiation process according to the service policy ID, and thus send a service establishment request carrying at least the UE ID and the service policy ID to the CN NF; the CN NF uses the service policy corresponding to the service policy ID to establish a service service of the corresponding service type for the UE based on the UE ID and the service policy ID carried in the service establishment request, and sends a service establishment request response to the RAN NF; after receiving the service establishment request response from the CN NF, the RAN NF cooperates with the CN NF to provide the UE with a service service of the corresponding service type, and returns a service establishment request response to the UE, which carries at least the UEID and the service type, indicating that the UE has successfully established a service of the requested service type for it.

[0173] For details on the business establishment process corresponding to the above scenario 1, please refer to Figure 5 The interaction process of scenario 1 in the illustrated embodiment, wherein the bearer service may be a RAN side network element, such as a RAN NF; the service establishment request initiated by the UE to the RAN NF may be a radio resource control (Radio Resource Control, RRC) establishment request, and accordingly, the service establishment request response returned by the RAN NF to the UE is an RRC establishment request response.

[0174] In the case where the UE sends a service establishment request carrying at least the requested service type to the RAN network storage function, that is, corresponding to scenario 2, the RAN network storage function may select a suitable service policy for the UE according to the service type, and determine the RAN NF associated with the service policy ID selected for the UE based on the RAN NF information associated with each service policy ID obtained by the RAN network storage function in the service policy negotiation process, thereby sending a service establishment indication to the RAN NF, and the indication carries at least the UE ID and the service policy ID, which is used to indicate that the RAN NF needs to use the service policy ID to establish a service for the UE; the RAN NF determines the CN NF associated with the service policy ID based on the service establishment indication and the service policy related information broadcasted to it by the RAN network storage function in the service policy negotiation process, thereby sending a service establishment request carrying at least the UE ID and the service policy ID to the CN NF; the CN NF uses the service policy corresponding to the service policy ID to establish a service of the corresponding service type for the UE based on the UE ID and the service policy ID carried in the service establishment request, and sends a service establishment request response to the RAN NF; the RAN After receiving the service establishment request response from the CN NF, the NF cooperates with the CN NF to provide the UE with service services of the corresponding service type, and sends a service establishment indication response carrying at least the UEID and the service type to the RAN network storage function; the RAN network storage function further returns a service establishment request response to the UE, which carries at least the UE ID and the service type, indicating that the UE has successfully established a service of the service type it requested.

[0175] For details on the business establishment process corresponding to the above scenario 2, please refer to Figure 5 In the interactive process of scenario 2 in the illustrated embodiment, the service establishment request initiated by the UE to the RAN network storage function may be an RRC establishment request, and accordingly, the service establishment request response returned by the RAN network storage function to the UE is an RRC establishment request response.

[0176] Combine the following Figure 6 The specific embodiment shown is an example of the service establishment method in the embodiment of the present application, and the specific process is as follows:

[0177] Step 0. The RAN network storage function sends the service request configuration, including service policy information, reporting information configuration, etc. It can be understood that this step is the service request configuration process before the service establishment process.

[0178] The service policy information is an optional service policy information sent by the network to the UE, including a service policy ID, the associated service type is a multimedia video service, the service policy applicable condition is that the UE can request the network's artificial intelligence (AI) video quality enhancement service when the link quality reaches the configured threshold, the associated RAN side bearer service, and AI service information, i.e., RAN NF information;

[0179] Reporting information configuration refers to the information that the UE needs to report when establishing a service, including UE ID, service type, selected service policy ID, requested service capability, air interface link quality information, etc.

[0180] When the UE selects a service policy autonomously but the air interface link quality does not reach the configured threshold, the following process is executed:

[0181] Step 1. The UE sends an RRC establishment request to the RAN side bearer service, which includes the UE ID, the requested service type is multimedia video service, and the selected service policy ID;

[0182] Step 2. The RAN side bearer service sends a service establishment request to the user plane function (UPF) configured by the service policy, carrying the UE ID, the requested service type and the selected service policy ID; wherein the UPF is a CN NF;

[0183] Step 3. UPF sends a service establishment request response to the RAN side bearer service;

[0184] Step 4. The RAN side bearer service sends an RRC establishment request response to the UE, carrying the UE ID and the service type of the response.

[0185] When the air interface link quality reaches the configured threshold, the UE executes the following process:

[0186] Step 5. The UE initiates a service establishment request to the AI ​​enhanced service through the Media Access Control (MAC) control element (CE) through the RAN side bearer service, carrying the UE ID, the requested service type is multimedia video service, the requested AI reasoning service, the selected service policy ID and the bearer service information of the established connection;

[0187] Step 6. The AI ​​enhanced service sends a service establishment request to the UPF configured by the service policy, carrying the UE ID, the requested service type, and the selected service policy ID;

[0188] Step 7. The UPF sends a service establishment request response to the AI ​​enhanced service, and the AI ​​enhanced service sends the service establishment request response to the RAN side bearer service;

[0189] Step 8. The RAN side bearer service sends a service request response through MAC CE, carrying the UE ID and the response service type.

[0190] Through the service policy configuration issued by the RAN network storage function proposed in the embodiment of the present application, the UE can directly initiate a service request to the network NF according to the requested service type and the selected service policy, and the network NF provides services or reserves resources based on the pre-negotiated service policy. If based on the existing network function, when the UE needs to request a new related service during the service establishment process, it needs to be forwarded to the core network element, such as the Policy Control Function (PCF), through the network NF (such as AMF). The PCF initiates the call update of the CN side service, and then notifies the NF on the RAN side to perform the service update configuration of the NF on the RAN side. The signaling interaction process is complicated, and the established air interface connection may also be affected by the newly added service.

[0191] In the service establishment method of the embodiment of the present application, the UE sends a service establishment request to the RAN network element, wherein the service establishment request includes the UE ID and the requested service type, and the RAN network element is a RAN network function NF or a RAN network storage function. When the RAN network element is a RAN NF, the service establishment request also includes the service policy ID selected by the UE. The embodiment of the present application proposes a new RAN-side function, namely, the RAN network storage function, to assist the mutual discovery and calling of the RAN NF and the CN NF, simplify the signaling interaction between the NFs, realize the rapid establishment of services, and reduce the delay, thereby reducing the complexity of cross-domain calls in the service establishment process.

[0192] See also Figure 3 , Figure 3 is a flow chart of a service establishment method performed by a RAN network storage function provided in an embodiment of the present application, such as Figure 3 As shown, the following steps are included:

[0193] Step 301: Receive a service establishment request sent by a UE, wherein the service establishment request includes a UE ID and a requested service type.

[0194] Step 302: Determine a selected service policy ID according to the service establishment request, and send a service establishment indication to the RAN NF associated with the service policy ID, wherein the service establishment indication includes the UE ID and the service policy ID.

[0195] Optionally, after step 302, the method further includes:

[0196] Receive a service establishment indication response sent by the RAN NF, wherein the service establishment indication response includes the UE ID and the service type.

[0197] Sending a service establishment request response to the UE, wherein the service establishment request response includes the UE ID and the service type.

[0198] Optionally, before step 301, the method further includes:

[0199] Send a service request configuration to the UE, wherein the service request configuration includes service policy information and reporting configuration information, the service policy information includes at least one service policy ID to be selected and the service type and service policy applicability condition associated with each service policy ID to be selected, and the reporting configuration information includes the device ID and the service type.

[0200] Optionally, the service policy information further includes at least one of a service policy priority, associated RAN NF information, associated CNNF information, a service capability of the service policy, a geographical scope of application of the service policy, and a time scope of application of the service policy.

[0201] Optionally, the reported configuration information also includes at least one of requested service capability, link quality information and device capability information.

[0202] Optionally, the service establishment request also includes at least one of requested service capability, link quality information and UE capability information.

[0203] It should be noted that this embodiment is as Figure 2 The implementation method of the RAN network storage function side corresponding to the embodiment shown, its specific implementation method and the above optional implementation methods can be found in Figure 2 The related introduction in the illustrated embodiments can achieve the same technical effect, and will not be repeated here to avoid repetition.

[0204] Optionally, before sending the service request configuration to the UE, the method further includes:

[0205] Sending a service policy request to the CN NF, wherein the service policy request includes a requested service policy ID and its associated service type and RAN NF information;

[0206] receiving a service policy request response sent by the CN NF, wherein the service policy request response includes the service policy ID;

[0207] Sending service policy related information to the RAN NF associated with the service policy ID, wherein the service policy related information includes the service policy ID and its associated service type, RAN NF information, and CN NF information.

[0208] That is, the RAN network storage function and the CN NF can negotiate service policies to support rapid service establishment. When subsequent services are established, the RAN NF can quickly call the corresponding service policy from the CN NF to provide service services or reserve resources for the service policy according to the pre-negotiated service policy.

[0209] Specifically, the RAN network storage function may send a service policy request to the CN NF, wherein the request carries at least the requested service policy ID, the associated service type, and the associated RAN NF information.

[0210] The associated RAN NF information may include information of a single RAN NF associated with a service policy, or may include information of a RAN NF set associated with a service policy, that is, information of a RAN NF or RAN NF set that needs to provide corresponding services when establishing a certain service, including but not limited to NF ID, NF IP address, NF type, etc.

[0211] After receiving the service policy request, the CN NF determines whether the service policy ID and service type requested by the RAN network storage function are satisfied according to whether the service type requested is supported. If it is determined that the service policy ID and service type are satisfied, the CN NF responds to the service policy request and returns a service policy request response carrying at least the service policy ID to the RAN network storage function. The CN NF may also store the service policy ID and its associated RAN NF information.

[0212] The RAN network storage function may also broadcast the service policy related information corresponding to the service policy ID to the related RAN NF, that is, the RAN NF or RAN NF set associated with the service policy ID, so that the RAN NF obtains the related information of the service policy ID.

[0213] The service policy related information at least includes the service policy ID, associated service type, associated RAN NF information, associated CN NF information and other information.

[0214] The associated CN NF information may include information of a single CN NF associated with the service policy, or may include information of a CN NF set associated with the service policy, that is, information of the CN NF or CN NF set that needs to provide corresponding services when establishing a certain service, including but not limited to NF ID, NF IP address, NF type, etc.

[0215] In this way, RAN NF can be associated with the service policy and can obtain the CN NF information associated with the associated service policy. After the service policy negotiation, the UE can directly initiate a service establishment request to the RAN NF based on the selected service policy, and the RAN NF can also quickly initiate a service establishment request to the associated CN NF.

[0216] Optionally, the service policy request also includes service capabilities required to be provided by the CN NF.

[0217] In one implementation, when the RAN network storage function initiates a service policy request to the CN NF, the request may also carry the service capabilities required to be provided by the CN NF, that is, the service capabilities required to be provided by the CN NF when establishing a certain service.

[0218] For example, for a certain UPF service policy S1, its service type is data class, and UPF needs to establish a user plane connection with general link quality for the UE; for service policy S2, its service type is AR interaction class, and UPF needs to establish a user plane connection with higher link quality for the UE.

[0219] Through this implementation, when negotiating service policies with CN NF, CNNF can be required to provide corresponding service capabilities according to service usage requirements, so that CN NF can provide services to UE according to its required service capabilities and ensure the service quality of UE.

[0220] Optionally, the service policy request response further includes at least one of an available geographical location, available time, service capability and security capability of the service policy ID.

[0221] In one implementation, when the CN NF returns a service policy request response to the RAN network storage function, the CN NF may also carry the available geographic location, available time, service capabilities, security capabilities, etc. of the service policy ID in the response to indicate the scope of application of the service policy, the service capabilities and security capabilities that the CN NF can provide, etc.

[0222] The service capability refers to the ability of a CN NF to provide services. For example, a CN NF supports AI services, and its service capability is indicated by supported algorithms, processing delays, etc.; a CN NF supports information open services, and its service capability is indicated by supported open information types, etc.

[0223] The security capability refers to the security policy of the CN NF. For example, Unified Data Management (UDM) provides different security policies, algorithms, keys, etc. for different services, where UDM is a type of CN NF.

[0224] In this implementation, by indicating the applicable scope of the RAN network storage function service policy, the service capability and security capability of the CN NF and other information, the RAN network storage function can be assisted to reasonably select and use the service policy according to the service requirements of the UE.

[0225] Optionally, the business policy related information further includes at least one of business policy priority, feedback configuration, available geographical location of the business policy ID, available time, security capability and quality of service (QoS) requirements.

[0226] In one implementation, the service policy related information broadcasted by the RAN network storage function to the RAN NF may also include service policy priority, feedback configuration, service policy available geographic location, service policy available time, security capabilities, QoS requirements, etc.

[0227] The service policy priority refers to the processing priority when the RAN NF processes multiple service policies. The service policy priority can be configured according to the service type, for example, the priority of interactive services is higher than that of transmission services; different service policies for the same service type can be configured according to the service capabilities associated with the service policies, for example, for AI services, the priority of services associated with lower AI processing delay is higher than that of services associated with higher AI processing delay.

[0228] The feedback configuration is to configure the RAN NF to feedback the relevant information of the service establishment. Specifically, when the UE directly initiates a service establishment request to the RANNF, or the network configures the RAN NF to feedback the relevant information of the service establishment, the RAN NF reports the relevant information of the service establishment to the RAN network storage function. For example, the AI ​​function feedback is the AI ​​capability information provided by the UE requesting the service, and the bearer management function feedback is the QoS information of the radio bearer established by the UE.

[0229] The security capability refers to the security level of the service policy. For example, different services provide different security policies, algorithms, keys, etc.

[0230] The QoS requirement refers to the QoS requirement that needs to be guaranteed when the RAN NF provides the corresponding service. For example, the RAN side bearer service establishes different bearers for voice and data interaction services to meet different data transmission rate, latency and other requirements; for another example, the RAN side computing service reserves different computing resources and data cache space for different VR services in advance.

[0231] In this implementation, by indicating more specific service policy related information to the RAN NF, it is possible to assist the RAN NF in reasonably using and selecting service policies and provide more accurate service quality assurance services.

[0232] The process of interaction between RAN network storage function and CN NF for service policy negotiation can be as follows: Fig.14 shown.

[0233] Optionally, before sending the service policy request to the CN NF, the method further includes:

[0234] Sending a service discovery request to a CN network repository function (Network Repository Function, NRF), wherein the service discovery request includes at least one of the requested CN NF information supporting the service policy and the requested service type;

[0235] A service discovery response sent by the CN NRF is received, wherein the service discovery response includes matching CN NF information and a matching CN NF address.

[0236] That is, the RAN network storage function can assist the RAN side NF to realize cross-domain discovery and invocation of core network services. The RAN network storage function can be responsible for service discovery of RAN NF / CN NF in different areas, such as a base station coverage area, a base station group coverage area, an AMF service area, etc.

[0237] Before the service policy negotiation process, the CN NF and CN NRF first perform a service registration process, so that the CN NRF stores the information of the CN NF that supports service policy negotiation. The RAN network storage function then performs a service discovery process with the CN NRF to obtain the information of the CN NF that supports service policy negotiation, so that the service policy negotiation can be performed with the CN NF that supports service policy negotiation to support rapid service establishment.

[0238] Specifically, the CN NF may initiate a service registration request to the CN NRF, and the request carries at least a support service policy indication, that is, indicates that the CN NF supports the service policy negotiation function.

[0239] The CN NRF may respond to the service registration request, store the registered CN NF information, and return a service registration response to the CN NF.

[0240] The RAN network storage function initiates a service discovery request to the CN NRF, and the request carries at least one of the requested CN NF information supporting the service policy and the requested service type, wherein the requested CNNF information supporting the service policy may be the requested CN NF ID or CN NF type supporting the service policy.

[0241] The CN NRF may respond to the service discovery request, search for CN NF information matching the CN NF information supporting the service policy and the requested service type requested by the RAN network storage function from the registered CN NF information, and carry the matching CN NF information and the matching CN NF address in the service discovery response to the RAN network storage function. The matching CN NF information may include a matching CN NF type, a matching CN NF or a CN NF set, and the matching CN NF address may include a matching single CN NF address or a matching CN NF set address.

[0242] For example, a RAN network storage function initiates a service discovery request to discover UPFs that support service policy negotiation. CNNRF sends a service discovery response and sends the UPF address information that supports different service types to the RAN network storage function.

[0243] In this implementation, the RAN network storage function can assist the RAN-side NF in realizing cross-domain discovery and calling of core network services, thereby supporting rapid service establishment.

[0244] Optionally, the service registration request also includes at least one of the service type supported by the CN NF, the supported geographical scope, the available time, the service capability and the security capability.

[0245] In one implementation, when the CN NF initiates a service registration request to the CN NRF, the CN NF may also carry in the request information such as the service type supported by the CNNF, the supported geographical scope, the available time, the service capability and the security capability.

[0246] The service types supporting service policies refer to the service types supported by CN NF for service policy negotiation. For example, a UPF supports service policy negotiation, and the service types it supports include voice services, data services, interactive services, etc.; for example, a UDM supports service policy negotiation, and the service types it supports include data services, collection services, etc.

[0247] The service capability refers to the ability of a CN NF to provide services. For example, a CN NF supports AI services, and its service capability is indicated by supported algorithms, processing delays, etc.; a CN NF supports information open services, and its service capability is indicated by supported open information types, etc.

[0248] The security capability refers to the security policy of the CN NF. For example, UDM provides different security policies, algorithms, keys, etc. for different services.

[0249] The supported service scope refers, for example, to the geographical area where the CN NF can provide services.

[0250] The available time refers to the time range within which the CN NF supports providing services.

[0251] In this implementation, by registering more specific information related to the service policies supported by the CN NF and its own capability information, the RAN network storage function can obtain detailed and comprehensive CN NF information, which facilitates subsequent targeted service policy negotiation.

[0252] Optionally, the service discovery response also includes at least one of the service type, supported geographical scope, available time, service capability and security capability supported by the matching CN NF.

[0253] In one implementation, when the CN NRF returns a service discovery response to the RAN network storage function, it may also carry in the response information such as the service type, supported geographical scope, available time, service capability, security capability, etc. supported by the matching CN NF. The specific indicated information items may be determined based on the information items carried by the CN NF when registering with the CN NRF.

[0254] In this way, by sending more and more comprehensive CN NF information to the RAN network storage function in the service discovery process, the RAN network storage function can obtain detailed and comprehensive CN NF information, which is convenient for subsequent targeted service policy negotiation.

[0255] The process of interaction between CN NF, CN NRF and RAN network storage function for service registration and discovery can be as follows: Fig.10 shown.

[0256] In the service establishment method of the embodiment of the present application, the RAN network storage function receives a service establishment request sent by the UE, wherein the service establishment request includes the UE ID and the requested service type; according to the service establishment request, the selected service policy ID is determined, and a service establishment indication is sent to the RAN NF associated with the service policy ID, wherein the service establishment indication includes the UE ID and the service policy ID. The embodiment of the present application proposes a new function on the RAN side, namely the RAN network storage function, to assist the mutual discovery and calling of the RAN NF and the CN NF, simplify the signaling interaction between the NFs, realize the rapid establishment of services, reduce latency, and thus reduce the complexity of cross-domain calls in the service establishment process.

[0257] See also Figure 4 , Figure 4 is a flow chart of a service establishment method performed by a RAN NF provided in an embodiment of the present application, such as Figure 4 As shown, the following steps are included:

[0258] Step 401: Receive a first service establishment request sent by a UE, wherein the first service establishment request includes a UEID, a requested service type, and a selected service policy ID.

[0259] Step 402: Send a third service establishment request to the core network CN NF associated with the service policy ID, wherein the third service establishment request includes the UE ID and the service policy ID.

[0260] Optionally, after step 402, the method further includes:

Accordingly, the above sending a second service establishment request response to the UE is replaced by: sending a service establishment indication response to the RAN network storage function, wherein the service establishment indication response includes the UE ID and the service type.

[0264] Optionally, the service establishment request also includes at least one of requested service capability, link quality information and UE capability information.

[0266] Receive service policy related information sent by the RAN network storage function, wherein the service policy related information includes the requested service policy ID and its associated service type, RAN NF information and CN NF information.

[0267] Optionally, the service policy related information further includes at least one of service policy priority, feedback configuration, available geographical location of the service policy ID, available time, security capability and QoS requirement.

[0268] It should be noted that this embodiment is as Figure 2 , Figure 3 The implementation method of the RAN NF side corresponding to the embodiment shown in the figure, its specific implementation method and the above optional implementation methods can be found in Figure 2 or Figure 3 The related introduction in the illustrated embodiments can achieve the same technical effect, and will not be repeated here to avoid repetition.

[0269] In the service establishment method in the embodiment of the present application, the RAN NF receives a first service establishment request sent by the UE, or receives a service establishment indication sent by the RAN network storage function, wherein the first service establishment request includes the UE ID, the requested service type and the selected service policy ID, and the service establishment indication includes the UE ID and the selected service policy ID; and sends a third service establishment request to the core network CN NF associated with the service policy ID, wherein the third service establishment request includes the UE ID and the service policy ID. The embodiment of the present application proposes a new function on the RAN side, namely the RAN network storage function, to assist the mutual discovery and calling of the RAN NF and the CN NF, simplify the signaling interaction between the NFs, realize the rapid establishment of services, and reduce latency, thereby reducing the complexity of cross-domain calls in the service establishment process.

[0270] See also Figure 7 , Figure 7 is a flow chart of a service registration method performed by a CN NF provided in an embodiment of the present application, such as Figure 7 As shown, the following steps are included:

[0271] Step 701: Send a service registration request to the CN NRF, wherein the service registration request includes a support service policy indication, which is used to indicate that the CN NF supports a service policy negotiation function.

[0272] Optionally, after step 701, the method further includes:

[0273] Receive the service registration response sent by the CN NRF.

[0274] In this embodiment, the CN NF may initiate a service registration request to the CN NRF, and the request carries at least a support service policy indication to indicate that the CN NF supports the service policy negotiation function.

[0275] The CN NRF may respond to the service registration request, store the registered CN NF information, and return a service registration response to the CN NF to indicate successful registration, so that the CN NF receives the service registration response sent by the CN NRF.

[0276] Optionally, the service registration request also includes at least one of the service type supported by the CN NF, the supported geographical scope, the available time, the service capability and the security capability.

[0277] In one implementation, when the CN NF initiates a service registration request to the CN NRF, the CN NF may also carry in the request information such as the service type supported by the CNNF, the supported geographical scope, the available time, the service capability and the security capability.

[0278] The service types supporting service policies refer to the service types supported by CN NF for service policy negotiation. For example, a UPF supports service policy negotiation, and the service types it supports include voice services, data services, interactive services, etc.; for example, a UDM supports service policy negotiation, and the service types it supports include data services, collection services, etc.

[0279] The service capability refers to the ability of a CN NF to provide services. For example, a CN NF supports AI services, and its service capability is indicated by supported algorithms, processing delays, etc.; a CN NF supports information open services, and its service capability is indicated by supported open information types, etc.

[0280] The security capability refers to the security policy of the CN NF. For example, UDM provides different security policies, algorithms, keys, etc. for different services.

[0281] The supported service scope refers, for example, to the geographical area where the CN NF can provide services.

[0282] The available time refers to the time range within which the CN NF supports providing services.

[0283] In this implementation, by registering more specific information related to the service policies supported by the CN NF and its own capability information, the RAN network storage function can obtain detailed and comprehensive CN NF information, which facilitates subsequent targeted service policy negotiation.

[0284] In the service registration method of the embodiment of the present application, the CN NF sends a service registration request to the CN NRF, wherein the service registration request includes a support service policy indication, which is used to indicate that the CN NF supports the service policy negotiation function. In this way, through the service registration process, the CN NRF can store the registered CN NF information supporting the service policy negotiation function, thereby facilitating the RAN network storage function to realize cross-domain discovery and call of the CN NF.

[0285] See also Figure 8 , Figure 8 is a flow chart of a service discovery method performed by a RAN network storage function provided in an embodiment of the present application, such as Figure 8 As shown, the following steps are included:

[0286] Step 801: Send a service discovery request to the CN NRF, wherein the service discovery request includes at least one of the requested CN NF information supporting the service policy and the requested service type.

[0287] Step 802: Receive a service discovery response sent by the CN NRF, wherein the service discovery response includes matching CN NF information and a matching CN NF address.

[0288] That is, the RAN network storage function can assist the RAN side NF to realize cross-domain discovery and invocation of core network services. The RAN network storage function can be responsible for service discovery of RAN NF / CN NF in different areas, such as a base station coverage area, a base station group coverage area, an AMF service area, etc.

[0289] After the CN NF and CN NRF perform the service registration process, the CN NRF stores the CNNF information that supports service policy negotiation. The RAN network storage function then performs the service discovery process with the CN NRF to obtain the CNNF information that supports service policy negotiation, so that it can perform service policy negotiation with the CN NF that supports service policy negotiation to support rapid service establishment.

[0290] Specifically, the RAN network storage function initiates a service discovery request to the CN NRF, and the request carries at least one of the requested CN NF information supporting the service policy and the requested service type, wherein the requested CN NF information supporting the service policy may be, for example, the requested CN NF ID or CN NF type supporting the service policy.

[0291] The CN NRF may respond to the service discovery request, search for CN NF information matching the CN NF information supporting the service policy and the requested service type requested by the RAN network storage function from the registered CN NF information, and carry the matching CN NF information and the matching CN NF address in the service discovery response to the RAN network storage function. The matching CN NF information may include a matching CN NF type, a matching CN NF or a CN NF set, and the matching CN NF address may include a matching single CN NF address or a matching CN NF set address.

[0292] For example, a RAN network storage function initiates a service discovery request to discover UPFs that support service policy negotiation. CNNRF sends a service discovery response and sends the UPF address information that supports different service types to the RAN network storage function.

[0293] Optionally, the service discovery response also includes at least one of the service type, supported geographical scope, available time, service capability and security capability supported by the matching CN NF.

[0294] In one implementation, when the CN NRF returns a service discovery response to the RAN network storage function, it may also carry in the response information such as the service type, supported geographical scope, available time, service capability, security capability, etc. supported by the matching CN NF. The specific indicated information items may be determined based on the information items carried by the CN NF when registering with the CN NRF.

[0295] In this way, by sending more and more comprehensive CN NF information to the RAN network storage function in the service discovery process, the RAN network storage function can obtain detailed and comprehensive CN NF information, which is convenient for subsequent targeted service policy negotiation.

[0296] In the service discovery method in the embodiment of the present application, the RAN network storage function sends a service discovery request to the CN NRF, wherein the service discovery request includes at least one of the requested CN NF information supporting the service policy and the requested service type; and receives a service discovery response sent by the CN NRF, wherein the service discovery response includes the matching CN NF information and the matching CN NF address. In this way, the RAN network storage function can realize cross-domain discovery of core network services through the service discovery process, and then can perform service calls based on the obtained CN NF information, supporting rapid service establishment.

[0297] See also Fig. 9 , Fig. 9 is a flow chart of a service registration and discovery method performed by a CN NRF provided in an embodiment of the present application, such as Fig. 9 As shown, the following steps are included:

[0298] Step 901: Receive a service registration request sent by a CN NF, wherein the service registration request includes a service policy support indication, which is used to indicate that the CN NF supports a service policy negotiation function.

[0299] Step 902: Receive a service discovery request sent by the RAN network storage function, wherein the service discovery request includes at least one of the requested CN NF information supporting the service policy and the requested service type.

[0300] Step 903: Send a service discovery response to the RAN network storage function, wherein the service discovery response includes matching CN NF information and a matching CN NF address.

[0301] Optionally, after step 901, the method further includes:

[0302] Send a service registration response to the CN NF.

[0303] Optionally, the service registration request also includes at least one of the service type supported by the CN NF, the supported geographical scope, the available time, the service capability and the security capability.

[0304] Optionally, the service discovery response also includes at least one of the service type, supported geographical scope, available time, service capability and security capability supported by the matching CN NF.

[0305] It should be noted that this embodiment is as Figure 7 , Figure 8 The implementation method of the CN NRF side corresponding to the embodiment shown in the figure, its specific implementation method and the above optional implementation methods can be found in Figure 7 or Figure 8 The related introduction in the illustrated embodiments can achieve the same technical effect, and will not be repeated here to avoid repetition.

[0306] The above process of interaction between CN NF, CN NRF and RAN network storage function for service registration and discovery can be as follows: Fig.10 shown.

[0307] In the service registration and discovery method in the embodiment of the present application, the CN NRF receives a service registration request sent by the CN NF, wherein the service registration request includes a support service policy indication, which is used to indicate that the CN NF supports the service policy negotiation function; receives a service discovery request sent by the RAN network storage function, wherein the service discovery request includes at least one of the requested CN NF information supporting the service policy and the requested service type; sends a service discovery response to the RAN network storage function, wherein the service discovery response includes the matching CN NF information and the matching CN NF address. In this way, through the service registration and discovery process, the RAN network storage function can realize cross-domain discovery and calling of core network services, and then can perform service calls based on the obtained CN NF information, supporting rapid service establishment.

[0308] See also Fig.11 , Fig.11 is a flow chart of a service policy negotiation method performed by a RAN network storage function provided in an embodiment of the present application, such as Fig.11 As shown, the following steps are included:

[0309] Step 1101: Send a service policy request to the CN NF, wherein the service policy request includes a requested service policy ID and its associated service type and RAN NF information.

[0310] Step 1102: Receive a service policy request response sent by the CN NF, wherein the service policy request response includes the service policy ID.

[0311] Step 1103: Send service policy related information to the RAN NF associated with the service policy ID, wherein the service policy related information includes the service policy ID and its associated service type, RAN NF information, and CN NF information.

[0312] In this embodiment, the RAN network storage function and the CN NF can negotiate service policies to support rapid service establishment. When a subsequent service is established, the RAN NF can quickly call the corresponding service policy from the CN NF to provide service services or reserve resources for the service policy according to the service policy negotiated in advance.

[0313] Specifically, the RAN network storage function may send a service policy request to the CN NF, wherein the request carries at least the requested service policy ID, the associated service type, and the associated RAN NF information.

[0314] The associated RAN NF information may include information of a single RAN NF associated with a service policy, or may include information of a RAN NF set associated with a service policy, that is, information of a RAN NF or RAN NF set that needs to provide corresponding services when establishing a certain service, including but not limited to NF ID, NF IP address, NF type, etc.

[0315] After receiving the service policy request, the CN NF determines whether the service policy ID and service type requested by the RAN network storage function are satisfied according to whether the service type requested is supported. If it is determined that the service policy ID and service type are satisfied, the CN NF responds to the service policy request and returns a service policy request response carrying at least the service policy ID to the RAN network storage function. The CN NF may also store the service policy ID and its associated RAN NF information.

[0316] The RAN network storage function may also broadcast the service policy related information corresponding to the service policy ID to the related RAN NF, that is, the RAN NF or RAN NF set associated with the service policy ID, so that the RAN NF obtains the related information of the service policy ID.

[0317] The service policy related information at least includes the service policy ID, associated service type, associated RAN NF information, associated CN NF information and other information.

[0318] The associated CN NF information may include information of a single CN NF associated with the service policy, or may include information of a CN NF set associated with the service policy, that is, information of the CN NF or CN NF set that needs to provide corresponding services when establishing a certain service, including but not limited to NF ID, NF IP address, NF type, etc.

[0319] In this way, RAN NF can be associated with the service policy and can obtain the CN NF information associated with the associated service policy. After the service policy negotiation, the UE can directly initiate a service establishment request to the RAN NF based on the selected service policy, and the RAN NF can also quickly initiate a service establishment request to the associated CN NF.

[0320] Optionally, the service policy request also includes service capabilities required to be provided by the CN NF.

[0321] In one implementation, when the RAN network storage function initiates a service policy request to the CN NF, the request may also carry the service capabilities required to be provided by the CN NF, that is, the service capabilities required to be provided by the CN NF when establishing a certain service.

[0322] For example, for a certain UPF service policy S1, its service type is data class, and UPF needs to establish a user plane connection with general link quality for the UE; for service policy S2, its service type is AR interaction class, and UPF needs to establish a user plane connection with higher link quality for the UE.

[0323] Through this implementation, when negotiating service policies with CN NF, CNNF can be required to provide corresponding service capabilities according to service usage requirements, so that CN NF can provide services to UE according to its required service capabilities and ensure the service quality of UE.

[0324] Optionally, the service policy request response further includes at least one of an available geographical location, available time, service capability and security capability of the service policy ID.

[0325] In one implementation, when the CN NF returns a service policy request response to the RAN network storage function, the CN NF may also carry the available geographic location, available time, service capabilities, security capabilities, etc. of the service policy ID in the response to indicate the scope of application of the service policy, the service capabilities and security capabilities that the CN NF can provide, etc.

[0326] The service capability refers to the ability of a CN NF to provide services. For example, a CN NF supports AI services, and its service capability is indicated by supported algorithms, processing delays, etc.; a CN NF supports information open services, and its service capability is indicated by supported open information types, etc.

[0327] The security capability refers to the security policy of the CN NF. For example, Unified Data Management (UDM) provides different security policies, algorithms, keys, etc. for different services, where UDM is a type of CN NF.

[0328] In this implementation, by indicating the applicable scope of the RAN network storage function service policy, the service capability and security capability of the CN NF and other information, the RAN network storage function can be assisted to reasonably select and use the service policy according to the service requirements of the UE.

[0329] Optionally, the service policy related information further includes at least one of service policy priority, feedback configuration, available geographical location of the service policy ID, available time, security capability and QoS requirement.

[0330] In one implementation, the service policy related information broadcasted by the RAN network storage function to the RAN NF may also include service policy priority, feedback configuration, service policy available geographic location, service policy available time, security capabilities, QoS requirements, etc.

[0331] The service policy priority refers to the processing priority when the RAN NF processes multiple service policies. The service policy priority can be configured according to the service type, for example, the priority of interactive services is higher than that of transmission services; different service policies for the same service type can be configured according to the service capabilities associated with the service policies, for example, for AI services, the priority of services associated with lower AI processing delay is higher than that of services associated with higher AI processing delay.

[0332] The feedback configuration is to configure the RAN NF to feedback the relevant information of the service establishment. Specifically, when the UE directly initiates a service establishment request to the RANNF, or the network configures the RAN NF to feedback the relevant information of the service establishment, the RAN NF reports the relevant information of the service establishment to the RAN network storage function. For example, the AI ​​function feedback is the AI ​​capability information provided by the UE requesting the service, and the bearer management function feedback is the QoS information of the radio bearer established by the UE.

[0333] The security capability refers to the security level of the service policy. For example, different services provide different security policies, algorithms, keys, etc.

[0334] The QoS requirement refers to the QoS requirement that needs to be guaranteed when the RAN NF provides the corresponding service. For example, the RAN side bearer service establishes different bearers for voice and data interaction services to meet different data transmission rate, latency and other requirements; for another example, the RAN side computing service reserves different computing resources and data cache space for different VR services in advance.

[0335] In this implementation, by indicating more specific service policy related information to the RAN NF, it is possible to assist the RAN NF in reasonably using and selecting service policies and provide more accurate service quality assurance services.

[0336] In the service policy negotiation method in the embodiment of the present application, the RAN network storage function sends a service policy request to the CN NF, wherein the service policy request includes the requested service policy ID and its associated service type and RAN NF information; receives the service policy request response sent by the CN NF, wherein the service policy request response includes the service policy ID; sends service policy related information to the RAN NF associated with the service policy ID, wherein the service policy related information includes the service policy ID and its associated service type, RAN NF information and CN NF information. In this way, the RAN network storage function can prepare for calling service policies and providing service services when establishing services by negotiating service policies with the CN NF, thereby supporting rapid service establishment.

[0337] See also Fig.12 , Fig.12 is a flow chart of a service policy negotiation method performed by a CN NF according to an embodiment of the present application, such as Fig.12 As shown, the following steps are included:

[0338] Step 1201: Receive a service policy request sent by a RAN network storage function, wherein the service policy request includes a requested service policy ID and its associated service type and RAN NF information.

[0339] Step 1202: Send a service policy request response to the RAN network storage function, wherein the service policy request response includes the service policy ID.

[0340] Optionally, the service policy request also includes service capabilities required to be provided by the CN NF.

[0341] Optionally, the business policy request response further includes at least one of an available geographical location, available time, service capability and security capability of the business policy.

[0343] In the service policy negotiation method in the embodiment of the present application, the CN NF receives a service policy request sent by a RAN network storage function, wherein the service policy request includes a requested service policy ID and its associated service type and RAN NF information; and sends a service policy request response to the RAN network storage function, wherein the service policy request response includes the service policy ID. In this way, the RAN network storage function can prepare for calling service policies and providing service services when establishing a service by negotiating service policies with the CN NF, thereby supporting rapid service establishment.

In this way, the RAN network storage function notifies the relevant RAN NF of the acquired service policy related information by negotiating the service policy with the CN NF, so as to prepare for calling the service policy and providing service services when establishing the service, and support rapid service establishment.
