Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a service implementation method and device. Background Art

[0002] Based on the actual business development needs, there will be a need to sign a service based on a specific / designated effective area in the terminal's home location, and trigger and control the designated service according to the corresponding specific / designated effective area in the roaming location. For example, the scenario of triggering designated services (such as LOGO display, short video, etc.) in the effective areas such as "airport", "XX VIP lounge", and "XX gymnasium" in the roaming location.

[0003] Considering the flexibility of business development and network planning adjustments, it is difficult to configure the network location information of all roaming areas related to different services at the terminal's home location, or to pre-configure the PRA of different services in the entire network. Currently, there is no relevant technical solution to solve this problem.

[0004] Example of business scenario: The terminal signs a contract for a designated service in a certain effective area at the home location, such as implementing the corresponding service execution in certain designated places such as airports and railway stations across the country, such as entering the effective area to display a specific LOGO, watch short videos with unlimited traffic, or execute other access and mobility service policies, etc. For the above example scenario, if the contract is signed at the PCF (Policy Control Function) of the terminal's home location, it is necessary to configure the network-side location information of the effective area related to the whole network roaming location in advance (such as TAI (Tracking Area Identity), PRA (Presence Reporting Area), etc.).

[0039] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] To facilitate understanding of the technical solution provided by the present invention, the following contents are now introduced: In the 5G network, the PCF network element implements the policy control function. User policies are divided into terminal policies (UE Policy), access and mobility policies (AM Policy), and session policies (SM Policy). According to the 3GPP business process, the AMF (Access and Mobility Management Function) network element interacts with the PCF network element through the N15 interface to implement access and mobility policies (AM POLICY) and UE POLICY policy control; the SMF (Session Management Function) network element interacts with the PCF network element through the N7 interface to implement session class policies (SM POLICY) control.

[0041] Among them, AM POLICY can provide access policy control based on the terminal access location, such as frequency selection, SMF selection, access location control, bandwidth control, etc., so it is defined in the standard as being controlled by the PCF network element in the roaming area, that is, AM POLICY services can be provided in the roaming area based on designated areas or specific places (such as scenic spots, specific) according to the local business development needs of the roaming area. However, in terms of actual business development needs and the need to meet the needs of flexible business development, there will be terminals that sign AM POLICY in their home locations, but perform corresponding AM POLICY control and execution in the roaming area. For business scenarios where the scope of service provision in this scenario is unlimited, the vAM-PCF network element in the roaming area can directly execute the relevant policies after obtaining the corresponding policies from the hAM-PCF network element to which the terminal belongs; however, if the service needs to be provided in a specific area, such as policy control execution based on the TAI list or PRA information, there is currently no relevant solution.

[0042] For SM POLICY scenarios, if there is a need to trigger specific areas and control services in different roaming locations, it is difficult to configure regional information (such as TAI, PRA, etc.) of the entire network roaming location for the hAM-PCF network element to which the terminal belongs. At the same time, due to real-time adjustments in network planning and construction, it is also difficult to synchronize the updates of relevant information. Therefore, solutions for related scenarios also need to be considered.

[0043] In the 5G network, facing the complexity of 5G service scenarios, the diversification of service requirements, and the personalization of service experience, 3GPP introduced NWDAF (Network Data Analytics Function) network elements in 5GC, which provides new solutions for providing on-demand services and improving the efficiency of network resource utilization with its intelligent perception, real-time analysis and reasoning capabilities. NWDAF receives service analysis subscription requests from consumer 5GC NF (PCF, AMF, SMF, etc.) network elements, AF (Application Function) network elements, OAM (Operation Administration and Maintenance) network elements, etc., collects raw data from other related 5GC NF (PCF, AMF, SMF, etc.), AF (Application Function), OAM (Operation Administration and Maintenance) network elements, etc., and uses artificial intelligence, machine learning, reasoning and other advanced technical analysis and prediction models to intelligently analyze the raw data, and outputs the analysis results to consumer 5GC NF, AF, OAM, etc., to optimize network resource utilization and improve user terminal service experience.

[0044] Figure 1 This is one of the flow charts of the service implementation method provided by the present invention. Figure 1 As shown, the service implementation method provided by the present invention is applied to a first network device, and the method may include: Step 110: Acquire service information and / or effective area information of a designated service from a second network device; Step 120: When it is determined that the target terminal enters the effective area corresponding to the roaming location, a designated service is executed for the target terminal in the effective area based on the service information; The first network device is a roaming network device of the target terminal, and the second network device is a home network device of the target terminal; the service information and the effective area information are determined when the target terminal activates a designated service.

[0045] In step 110, the second network device can determine whether the geographical area where the target terminal is located is located in a roaming area that provides the specified service based on the acquired network location configuration information (such as AMF ID, GUAMI, etc.) currently accessed by the target terminal.

[0046] If so, the second network device will send the service information and / or effective area information of the designated service to the first network device.

[0047] The first network device may receive the service information and / or effective area information sent by the second network device.

[0048] The service information may include package information of the activated designated service (such as service ID, etc.).

[0049] The effective area information may include the region / province where the designated business is carried out and the geographical area information supported by the business, such as "XX Airport in XX Province", "XX Scenic Area in XX City", etc.

[0050] Designated services may include various types of voice services and data services, such as displaying a specific LOGO, providing specific voice services (scenic spot guides, venue precautions, etc.), providing short video services with specific content, etc.

[0051] In step 120, the first network device acquires the location information of the target terminal in real time, and determines whether the target terminal has entered the effective area based on the service information and / or effective area information acquired from the second network device.

[0052] If so, the first network device will execute the designated service for the target terminal within the effective area based on the service information.

[0053] The service implementation method provided by the present invention can avoid configuring the network side location information of all the effective areas of different services in the roaming area in advance at the terminal's home location, thereby simplifying the process of executing the specified service in the effective area of ​​the roaming area and improving the feasibility of service implementation by determining the service information and the effective area information (non-network side location information) when the terminal activates the specified service, and executing the specified service when the terminal enters the effective area of ​​the roaming area.

[0054] In one embodiment, in order to specifically adapt to the scenario based on the AM POLICY service, the first network device may include a vAM-PCF network element and an AMF network element; the second network device may include an hAM-PCF network element; and the method may specifically include: The vAM-PCF network element obtains service information and / or effective area information from the hAM-PCF network element; When it is determined that the target terminal enters the effective area of ​​the roaming area, the vAM-PCF network element and the AMF network element use the service information to execute the designated service for the target terminal in the effective area.

[0055] It should be noted that the vAM-PCF network element and the hAM-PCF network element may be existing PCF network elements that are responsible for AM POLICY-based services, or may be newly defined PCF network elements used for AM POLICY-based services, and the embodiment of the present invention does not specifically limit this.

[0056] like Figure 2 As shown, in this embodiment, the workflow of the above network elements may be as follows: Step 210, the vAM-PCF network element initiates a request to the hAM-PCF network element to which the target terminal belongs to obtain the service information (AM POLICY) subscribed by the target terminal. At the same time, the request carries the user information and user location information (such as AMF ID, GUAMI, etc.) of the target terminal.

[0057] Step 220: The hAM-PCF network element determines whether the user is accessing the roaming area providing the designated service based on the effective area information pre-acquired when the target terminal activates the designated service and the location information of the target terminal received from the vAM-PCF network element. The location information of the target terminal is obtained by the vAM-PCF network element from the AMF network element.

[0058] If yes, the hAM-PCF network element sends the service information (such as service ID, etc.) and / or effective area information to the vAM-PCF network element.

[0059] If not, the hAM-PCF network element does not send the service information and effective area information to the vAM-PCF network element.

[0060] Step 230: The vAM-PCF network element executes the service logic of the specified service according to the locally pre-configured service execution logic information of the specified service and the network side location information of the corresponding effective area (such as TAI list, PRA information, etc.).

[0061] That is, after the vAM-PCF network element obtains the designated service information provided by the roaming area to which the target terminal has signed a contract from the hAM-PCF network element, the vAM-PCF network element cooperates with the AMF network element to complete the execution and control of the designated service in the effective area according to the pre-configured service execution logic information of the designated service and the network-side location information of the corresponding effective area: when the target terminal enters the effective area, the execution of the designated service is triggered; when the target terminal leaves the effective area, the execution of the designated service is stopped. The specific implementation scheme for realizing service control based on the TAI list or PRA method can be executed according to the operator's policy, and the present invention will not elaborate on it.

[0062] In one embodiment, before obtaining the service information and / or effective area information of the specified service from the second network device, the method may further include: Pre-configure the business execution logic information of the specified business and the network side location information of the effective area.

[0063] Specifically, in the present invention, the business support system in the roaming area can provide package information of the designated service, and synchronize the activation information of the designated service to the business support system of the relevant geographical area (such as province, city, etc.) that allows the contract of the designated service.

[0064] The activation information covers the basic package information of the designated service (such as the designated service ID, etc.) and the effective area information of the designated service. The effective area information includes the designated service development area, the geographical area supported by the service, etc., such as "xx Province-Airport", "xx Province-XX Scenic Area", etc.

[0065] The service support system at the terminal's home location can accept or reject the opening of the designated service to the terminal in this geographical area according to local management requirements and network conditions. If rejected, a rejection message will be sent to the service support system at the roaming location. When the terminal in this geographical area roams to the area where the designated service is provided, the terminal can be prompted by SMS or other means that its home location does not currently support the opening of the designated roaming service.

[0066] If the business support system at the terminal's location accepts the designated service and provides it to the local terminal, when the terminal applies for activation of the designated service, the business support system at the terminal's location will activate it to the terminal's contracted node, such as a PCF network element, and carry the service information and the corresponding effective area information of the service.

[0067] Specifically, Figure 2 Taking an example as an example, the service implementation method provided by the present invention may further include: Step 201, service activation: according to the above designated service activation process, the target terminal activates the designated service of the roaming area in the home area, including signing a roaming service contract with the hAM-PCF network element, which carries service information and / or corresponding effective area information.

[0068] Optionally, the service support system may also send the target terminal a contract-specific field identifier in the UDM / UDR for the AM POLICY service of the terminal's contract-based location.

[0069] Step 202, pre-configuration requirements: The vAM-PCF network element pre-configures the service execution logic information of the specified service and the relevant network-side location information of the local effective area corresponding to the specified service (such as the PRA or TAI list information corresponding to the "airport", etc.). Subsequently, when the target terminal enters or exits the effective area, the execution and control of the specified service is triggered; when the target terminal leaves the effective area, operations such as stop / pause are completed according to the predetermined rules.

[0070] Step 203: The vAM-PCF network element establishes a connection with the hAM-PCF network element.

[0071] After the target terminal completes the network registration process in the roaming location, the first network device and the second network device can establish a connection through the vAM-PCF network element and the hAM-PCF network element. The connection process may specifically include the following sub-steps: Step 2031: The AMF network element triggers two service discoveries to the NRF network elements vAM-PCF network element and hAM-PCF network element of the first network device based on the default configuration rule; Optionally, if in step 201 the business support system identifies the AM POLICY service of the terminal's contracted location in the UDM / UDR to which the target terminal belongs, and in the network registration process of the target terminal, the AMF network element obtains the terminal user's contract data from the terminal UDM / UDR, then the AMF network element can also implement step 2031 based on the specific field.

[0072] Step 2032: The AMF network element discovers the vAM-PCF network element and hAM-PCF network element information from the NRF network element service.

[0073] Step 2033: The AMF network element establishes an N15 connection with the vAM-PCF network element according to the standard definition process, and transmits the hAM-PCF network element address or domain name information to the vAM-PCF network element.

[0074] After completing step 203, the above step 210 may be entered.

[0075] In one embodiment, the specified service may be any of the following: Only used for services in the effective area of ​​the above roaming location; Used for services in different roaming areas.

[0076] It is understandable that when a designated service is a service used only in an effective area of ​​a certain roaming location, it can still be signed and promoted for use to users across the entire network.

[0077] When the designated service is a service used in effective areas of different roaming locations, the identifier of the designated service may be uniformly planned for the entire network.

[0078] Specifically, when the specified service can be implemented in the effective area of ​​the entire network, the service information (such as the service ID of the unified planning) of the entire network can be configured for the specified service in the service activation process. Figure 2 In steps S201, S220 and other steps, only the service information of the unified planning of the whole network needs to be exchanged.

[0079] When a specified service is only available in certain areas, the service effective area information corresponding to the specified service can be carried in the data opened to the PCF network element, or the service effective area information can be provided in the hAM-PCF network element static configuration.

[0080] Figure 3 This is the second flow chart of the service implementation method provided by the present invention. Figure 3 As shown, the service implementation method provided by the present invention is applied to the second network device, and the method may include: Step 310: Acquire location information of a target terminal from a first network device; Step 320: When it is determined that the target terminal is located in a roaming area where the designated service is provided, provide the first network device with service information and / or effective area information of the designated service; The first network device is a roaming network device of the target terminal, and the second network device is a home network device of the target terminal; The service information is used to implement the designated service of the target terminal in the effective area; the service information and the effective area information are determined when the target terminal activates the designated service.

[0081] In step 310, the second network device may obtain the network location configuration information (such as AMF ID, GUAMI, etc.) to which the target terminal is currently connected from the first network device.

[0082] In step 320, the second network device may determine whether the geographical area where the target terminal is located is in a roaming area that provides the designated service based on the acquired network location configuration information currently accessed by the target terminal.

[0083] If so, the second network device will send the service information and / or effective area information of the designated service to the first network device.

[0084] The first network device may receive the service information and / or effective area information sent by the second network device.

[0085] The service information may include package information of the activated designated service (such as service ID, etc.).

[0086] The effective area information may include the region / province where the designated business is carried out and the geographical area information supported by the business, such as "XX Airport in XX Province", "XX Scenic Area in XX City", etc.

[0087] Designated services may include various types of voice services and data services, such as displaying a specific LOGO, providing specific voice services (scenic spot guides, venue precautions, etc.), providing short video services with specific content, etc.

[0088] After receiving the service information and / or effective area information sent by the second network device, the first network device will obtain the location information of the target terminal in real time, and determine whether the target terminal has entered the effective area based on the service information and / or effective area information obtained from the second network device.

[0089] If so, the first network device will execute the designated service for the target terminal within the effective area based on the service information.

[0090] The service implementation method provided by the present invention can avoid configuring the network side location information of all the effective areas of different services in the roaming area in advance at the terminal's home location, thereby simplifying the process of executing the specified service in the effective area of ​​the roaming area and improving the feasibility of service implementation by determining the service information and the effective area information (non-network side location information) when the terminal activates the specified service, and executing the specified service when the terminal enters the effective area of ​​the roaming area.

[0091] In one embodiment, in order to specifically adapt to the scenario based on the AM POLICY service, the second network device may include an hAM-PCF network element; the first network device may include a vAM-PCF network element and an AMF network element; the method may specifically include: The hAM-PCF network element receives the location information of the target terminal sent by the vAM-PCF network element, and the location information of the target terminal is obtained by the vAM-PCF network element from the AMF network element; When the hAM-PCF network element determines that the target terminal is located in a roaming area where the designated service is provided, the hAM-PCF network element sends service information and / or effective area information of the designated service to the vAM-PCF network element.

[0092] It should be noted that the vAM-PCF network element and the hAM-PCF network element may be existing PCF network elements that are responsible for AM POLICY-based services, or may be newly defined existing PCF network elements used for AM POLICY-based services, and the embodiment of the present invention does not specifically limit this.

[0093] like Figure 2 As shown, in this embodiment, the workflow of the above network elements may be as follows: Step 210, the vAM-PCF network element initiates a request to the hAM-PCF network element to which the target terminal belongs to obtain the service information (AM POLICY) subscribed by the target terminal. At the same time, the request carries the user information and user location information (such as AMF ID, GUAMI, etc.) of the target terminal.

[0094] Step 220: The hAM-PCF network element determines whether the user is accessing the roaming area providing the designated service based on the effective area information pre-acquired when the target terminal activates the designated service and the location information of the target terminal received from the vAM-PCF network element. The location information of the target terminal is obtained by the vAM-PCF network element from the AMF network element.

[0095] If yes, the hAM-PCF network element sends the service information (such as service ID, etc.) and / or effective area information to the vAM-PCF network element.

[0096] If not, the hAM-PCF network element does not send the service information and effective area information to the vAM-PCF network element.

[0097] Step 230: The vAM-PCF network element executes the service logic of the specified service according to the locally pre-configured service execution logic information of the specified service and the network side location information of the corresponding effective area (such as TAI list, PRA information, etc.).

[0098] That is, after the vAM-PCF network element obtains the designated service information provided by the roaming area to which the target terminal has signed a contract from the hAM-PCF network element, the vAM-PCF network element cooperates with the AMF network element to complete the execution and control of the designated service in the effective area according to the pre-configured service execution logic information of the designated service and the network-side location information of the corresponding effective area: when the target terminal enters the effective area, the execution of the designated service is triggered; when the target terminal leaves the effective area, the execution of the designated service is stopped. The specific implementation scheme for realizing service control based on the TAI list or PRA method can be executed according to the operator's policy, and the present invention will not elaborate on it.

[0099] In one embodiment, the method may further include: In the process of opening the designated service at the target terminal, the service information and / or effective area information of the designated service sent by the service support system is received.

[0100] Specifically, in the present invention, the service support system of the roaming network device can provide package information of the designated service, and synchronize the activation information of the designated service to the service support system of the relevant geographical area (such as province, city, etc.) that allows the contract of the designated service.

[0101] The activation information covers the basic package information of the designated service (such as the designated service ID, etc.) and the effective area information of the designated service. The effective area information includes the designated service development area, the geographical area supported by the service, etc., such as "xx Province-Airport", "xx Province-XX Scenic Area", etc.

[0102] The service support system at the terminal's home location can accept or reject the opening of the designated service to the terminal in this geographical area according to local management requirements and network conditions. If rejected, a rejection message will be sent to the service support system at the roaming location. When the terminal in this geographical area roams to the area where the designated service is provided, the terminal can be prompted by SMS or other means that its home location does not currently support the opening of the designated roaming service.

[0103] If the business support system at the terminal's location accepts the designated service and provides it to the local terminal, when the terminal applies for activation of the designated service, the business support system at the terminal's location will activate it to the terminal's contracted node, such as a PCF network element, and carry the service information and the corresponding effective area information of the service.

[0104] Specifically, Figure 2 Taking an example as an example, the service implementation method provided by the present invention may further include: Step 201, service activation: according to the above designated service activation process, the target terminal activates the designated service of the roaming area in the home area, including signing a roaming service contract with the hAM-PCF network element, which carries service information and / or corresponding effective area information.

[0105] Optionally, the service support system may also send the target terminal a contract-specific field identifier in the UDM / UDR for the AM POLICY service of the terminal's contract-based location.

[0106] Step 202, pre-configuration requirements: The vAM-PCF network element pre-configures the service execution logic information of the specified service and the relevant network-side location information of the local effective area corresponding to the specified service (such as the PRA or TAI list information corresponding to the "airport", etc.). Subsequently, when the target terminal enters or exits the effective area, the execution and control of the specified service is triggered; when the target terminal leaves the effective area, operations such as stop / pause are completed according to the predetermined rules.

[0107] Step 203: The vAM-PCF network element establishes a connection with the hAM-PCF network element.

[0108] After the target terminal completes the network registration process in the roaming location, the first network device and the second network device can establish a connection through the vAM-PCF network element and the hAM-PCF network element. The connection process may specifically include the following sub-steps: Step 2031: The AMF network element triggers two service discoveries to the NRF network elements vAM-PCF network element and hAM-PCF network element of the first network device based on the default configuration rule; Optionally, if in step 201 the business support system identifies the AM POLICY service of the terminal's contracted location in the UDM / UDR to which the target terminal belongs, and in the network registration process of the target terminal, the AMF network element obtains the terminal user's contract data from the terminal UDM / UDR, then the AMF network element can also implement step 2031 based on the specific field.

[0109] Step 2032: The AMF network element discovers the vAM-PCF network element and hAM-PCF network element information from the NRF network element service.

[0110] Step 2033: The AMF network element establishes an N15 connection with the vAM-PCF network element according to the standard definition process, and transmits the hAM-PCF network element address or domain name information to the vAM-PCF network element.

[0111] After completing step 203, the above step 210 may be entered.

[0112] In one embodiment, the specified service may be any of the following: Only used for services in the effective area of ​​the above roaming location; Used for services in different roaming areas.

[0113] It is understandable that when a designated service is a service used only in an effective area of ​​a certain roaming location, it can still be signed and promoted for use to users across the entire network.

[0114] When the designated service is a service used in effective areas of different roaming locations, the identifier of the designated service may be uniformly planned for the entire network.

[0115] Specifically, when the specified service can be implemented in the effective area of ​​the entire network, the service information (such as the service ID of the unified planning) of the entire network can be configured for the specified service in the service activation process. Figure 2 In steps S201, S220 and other steps, only the service information of the unified planning of the whole network needs to be exchanged.

[0116] When a specified service is only available in certain areas, the service effective area information corresponding to the specified service can be carried in the data opened to the PCF network element, or the service effective area information can be provided in the hAM-PCF network element static configuration.

[0117] Figure 4 This is the third flow chart of the service implementation method provided by the present invention. Figure 4As shown, the service implementation method provided by the present invention is applied to a first network device, and the method may include: Step 410: receiving a trigger message sent by the second network device, and determining whether the target terminal enters the effective area based on the trigger message; Step 420: When the target terminal enters the effective area, a feedback message of the terminal entering the effective area is sent to the second network device; The trigger message includes effective area information, which is determined when the target terminal activates the designated service; The feedback message is used to trigger the specified service of the target terminal in the effective area; The first network device is a roaming network device of the target terminal, and the second network device is a home network device of the target terminal.

[0118] Before step 410, the second network device may obtain the current access location information (such as AMF ID, GUAMI, etc.) of the target terminal from the first network device, and determine whether the target terminal is located in a roaming area providing the specified service in combination with the pre-acquired effective area information.

[0119] If yes, the second network device will send a trigger message (eg, trigger) to the first network device to obtain a notification of the target terminal entering or exiting the effective area, wherein the trigger message includes effective area information.

[0120] If not, the second network device will not send a trigger message to the first network device.

[0121] Among them, the effective area information may include the region / province where the designated business is carried out and the geographical area information supported by the business, such as "XX Airport in XX Province", "XX Scenic Area in XX City", etc.

[0122] Designated services may include various types of voice services and data services, such as displaying a specific LOGO, providing specific voice services (scenic spot guides, venue precautions, etc.), providing short video services with specific content, etc.

[0123] In step 410, the first network device receives the trigger message and acquires event information of the target terminal entering or exiting the effective area based on the effective area information in the trigger message.

[0124] In step 420, when the first network device determines that the target terminal enters the effective area based on the event information of the target terminal entering and exiting the effective area, the first network device sends a feedback message of the terminal entering the effective area to the second network device.

[0125] After receiving the feedback message, the second network device can determine that the target terminal has entered the effective area, and the second network device will execute the designated service of the target terminal in the effective area based on the feedback message.

[0126] The service implementation method provided by the present invention can avoid pre-configuring the network side location information of all different service effective areas in the roaming area at the terminal's home location by triggering the target terminal's home network device to initiate the execution of the specified service in the effective area when the target terminal enters the effective area of ​​the roaming area, thereby simplifying the process of executing the specified service in the effective area of ​​the roaming area and improving the feasibility of service implementation.

[0127] In one embodiment, the method may further include: Receiving an indication message sent by the second network device; Based on the indication message, the designated service of the target terminal in the effective area is executed.

[0128] It should be noted that in addition to the second network device directly executing the designated service based on the feedback message, the second network device can also send an indication message to the first network device after receiving the feedback message, and the first network device can execute the designated service of the target terminal in the effective area based on the indication message.

[0129] The service implementation method provided by the present invention effectively expands the service scenarios because both the first network device and the second network device can execute the designated service of the target terminal in the effective area.

[0130] In one embodiment, in order to specifically adapt to the scenario based on the SM POLICY service, the first network device may include an SMF network element and an AMF network element; the second network device may include a PCF network element; the method may specifically include: The SMF network element receives the trigger message sent by the PCF network element, and obtains information from the AMF network element based on the trigger message whether the target terminal enters the effective area; When the target terminal enters the effective area, the SMF network element sends a feedback message to the PCF network element.

[0131] like Figure 5 As shown, in this embodiment, the workflow of the above network elements may be as follows: Step 510: The PCF network element determines whether the target terminal is currently in a roaming location (such as a province, city, etc.) that provides the specified service based on the location information in the effective area information and the current access location information of the target terminal obtained through the SMF network element (such as AMF ID, GUAMI, etc.). The location information of the target terminal is obtained by the SMF network element from the AMF network element.

[0132] If so, the PCF network element sends a trigger message to the N7 interface message of the SMF network element to obtain notification of the target terminal entering or leaving the effective area, where the trigger message includes effective area information (such as "airport", etc.).

[0133] If not, the PCF does not send a trigger message.

[0134] Step 520, the SMF network element subscribes to the AMF network element for events of the target terminal entering and exiting the effective area transmitted through the N7 interface according to the trigger obtained from the N7 interface, and feeds back the obtained entry and exit results to the PCF network element.

[0135] Step 530: The PCF network element executes specific service logic based on the information about the target terminal entering and exiting the effective area reported by the SMF network element: When the target terminal enters the effective area, the PCF network element executes the designated service of the target terminal in the effective area based on the relevant SM POLICY; when the target terminal leaves the effective area, the PCF network element terminates or suspends the designated service execution. When the target terminal session ends, the designated service process terminates.

[0136] In one embodiment, the first network device may further include a NWDAF network element, and the method may further include: The NWDAF network element receives the indication message sent by the PCF network element, and executes the designated service of the target terminal in the effective area based on the indication message.

[0137] Still Figure 5 For example, when the first network device includes a NWDAF network element, the method may further include the following steps: Step 530', the PCF network element implements intelligent service triggering based on the information of the target terminal entering and exiting the effective area reported by the SMF network element: When the target terminal enters the effective area, the PCF network element sends an indication message to the NWDAF network element through the N23 interface. After receiving the indication message, the NWDAF network element will intelligently execute and control the designated services of the target terminal in the effective area based on the indication message and pre-configured designated service rules.

[0138] When the target terminal leaves the effective area, the PCF network element can terminate or suspend the intelligent service process according to the operator's service policy.

[0139] In one embodiment, before receiving the trigger message sent by the second network device, the method may further include: The network-side location information of the pre-configured effective area.

[0140] Specifically, in the present invention, the business support system in the roaming area can provide package information of the designated service, and synchronize the activation information of the designated service to the business support system of the relevant geographical area (such as province, city, etc.) that allows the contract of the designated service.

[0141] The activation information covers the basic package information of the designated service (such as the designated service ID, etc.) and the effective area information of the designated service. The effective area information includes the designated service development area, the geographical area supported by the service, etc., such as "xx Province-Airport", "xx Province-XX Scenic Area", etc.

[0142] The service support system at the terminal's home location can accept or reject the opening of the designated service to the terminal in this geographical area according to local management requirements and network conditions. If rejected, a rejection message will be sent to the service support system at the roaming location. When the terminal in this geographical area roams to the area where the designated service is provided, the terminal can be prompted by SMS or other means that its home location does not currently support the opening of the designated roaming service.

[0143] If the business support system at the terminal's location accepts the designated service and provides it to the local terminal, when the terminal applies for activation of the designated service, the business support system at the terminal's location will activate it to the terminal's contracted node, such as a PCF network element, and carry the service information and the corresponding effective area information of the service.

[0144] Specifically, Figure 5 Taking an example as an example, the service implementation method provided by the present invention may further include: Step 501, service activation: according to the above-mentioned designated service activation process, the target terminal activates the designated service of the roaming area in the home area, including signing a roaming service contract with the PCF network element, which carries service information and / or effective area information.

[0145] Step 502, pre-configuration requirements: The AMF network element pre-configures the network side location information of the local effective area corresponding to the specified service (such as the PRA or TAI list information corresponding to the "airport", etc.).

[0146] Step 503: The SMF network element establishes a connection with the PCF network element.

[0147] After the target terminal completes the basic session establishment process, an N7 interface link can be implemented between the SMF network element and the PCF network element, wherein the PCC process can refer to the prior art and will not be described in detail in the present invention.

[0148] After completing step 503, the above step 510 may be entered.

[0149] In one embodiment, the specified service may be any of the following: Only used for services in the effective area of ​​the above roaming location; Used for services in different roaming areas.

[0150] It is understandable that when a designated service is a service used only in an effective area of ​​a certain roaming location, it can still be signed and promoted for use to users across the entire network.

[0151] When the designated service is a service used in effective areas of different roaming locations, the identifier of the designated service may be uniformly planned for the entire network.

[0152] Specifically, when the specified service can be implemented in the effective area of ​​the entire network, the service information (such as the service ID of the unified planning) of the entire network can be configured for the specified service in the service activation process. Figure 2 In steps S501, S510 and other steps, only the service information of the unified planning of the whole network needs to be exchanged.

[0153] Figure 6 This is the fourth flow chart of the service implementation method provided by the present invention. Figure 6 As shown, the service implementation method provided by the present invention is applied to the second network device, and the method may include: Step 610: Acquire location information of a target terminal from a first network device; Step 620: When it is determined that the target terminal is located in a roaming area where the designated service is provided, a trigger message is sent to the first network device; the trigger message is used to determine whether the target terminal enters an effective area; Step 630: Receive a feedback message sent by the first network device, where the feedback message is generated when it is determined that the target terminal enters the effective area; Step 640: Execute the designated service of the target terminal in the effective area based on the feedback message; The trigger message includes effective area information, which is determined when the target terminal activates the designated service; The first network device is a roaming network device of the target terminal, and the second network device is a home network device of the target terminal.

[0154] In step 610, the second network device may obtain the current access location information (such as AMF ID, GUAMI, etc.) of the target terminal from the first network device.

[0155] In step 620, the second network device may determine whether the target terminal is located in a roaming area providing a designated service based on the current access location information of the target terminal in combination with the pre-acquired effective area information.

[0156] If yes, the second network device will send a trigger message (eg, trigger) to the first network device to obtain a notification of the target terminal entering or exiting the effective area, wherein the trigger message includes effective area information.

[0157] If not, the second network device will not send a trigger message to the first network device.

[0158] Among them, the effective area information may include the region / province where the designated business is carried out and the geographical area information supported by the business, such as "XX Airport in XX Province", "XX Scenic Area in XX City", etc.

[0159] Designated services may include various types of voice services and data services, such as displaying a specific LOGO, providing specific voice services (scenic spot guides, venue precautions, etc.), providing short video services with specific content, etc.

[0160] In step 630, the first network device receives the trigger message and acquires event information of the target terminal entering or exiting the effective area based on the effective area information in the trigger message.

[0161] When the first network device determines that the target terminal enters the effective area based on the event information of the target terminal entering and exiting the effective area, the first network device sends a feedback message of the terminal entering the effective area to the second network device.

[0162] In step 640, after receiving the feedback message, the second network device can determine that the target terminal has entered the effective area, and the second network device will execute the designated service of the target terminal in the effective area based on the feedback message.

[0163] The service implementation method provided by the present invention can avoid pre-configuring the network side location information of all different service effective areas in the roaming area at the terminal's home location by triggering the target terminal's home network device to initiate the execution of the specified service in the effective area when the target terminal enters the effective area of ​​the roaming area, thereby simplifying the process of executing the specified service in the effective area of ​​the roaming area and improving the feasibility of service implementation.

[0164] In one embodiment, the method may further include: An indication message is sent to the first network device based on the feedback message, where the indication message is used to execute a designated service of the target terminal in the effective area.

[0165] It should be noted that in addition to the second network device directly executing the designated service based on the feedback message, the second network device can also send an indication message to the first network device after receiving the feedback message, and the first network device can execute the designated service of the target terminal in the effective area based on the indication message.

[0166] The service implementation method provided by the present invention effectively expands the service scenarios because both the first network device and the second network device can execute the designated service of the target terminal in the effective area.

[0167] In one embodiment, in order to specifically adapt to the scenario based on the SM POLICY service, the second network device may include a PCF network element; the first network device may include an SMF network element and an AMF network element; the method may specifically include: The PCF network element receives the location information of the target terminal sent by the SMF network element, and the location information of the target terminal is obtained by the SMF network element from the AMF network element; When it is determined that the target terminal is located in a roaming area that provides the specified service, the PCF network element sends a trigger message to the SMF network element; The PCF network element receives the feedback message sent by the SMF network element and executes the specified service of the target terminal in the effective area based on the feedback message.

[0168] like Figure 5 As shown, in this embodiment, the workflow of the above network elements may be as follows: Step 510: The PCF network element determines whether the target terminal is currently in a roaming location (such as a province, city, etc.) that provides the specified service based on the location information in the effective area information and the current access location information of the target terminal obtained through the SMF network element (such as AMF ID, GUAMI, etc.). The location information of the target terminal is obtained by the SMF network element from the AMF network element.

[0169] If so, the PCF network element sends a trigger message to the N7 interface message of the SMF network element to obtain notification of the target terminal entering or leaving the effective area, where the trigger message includes effective area information (such as "airport", etc.).

[0170] If not, the PCF does not send a trigger message.

[0171] Step 520, the SMF network element subscribes to the AMF network element for events of the target terminal entering and exiting the effective area transmitted through the N7 interface according to the trigger obtained from the N7 interface, and feeds back the obtained entry and exit results to the PCF network element.

[0173] In one embodiment, the first network device may further include a NWDAF network element, and the method may further include: The PCF network element sends the indication message to the NWDAF network element based on the feedback message.

[0174] Still Figure 5 For example, when the first network device includes a NWDAF network element, the method may further include the following steps: Step 530', the PCF network element implements intelligent service triggering based on the information of the target terminal entering and exiting the effective area reported by the SMF network element: When the target terminal enters the effective area, the PCF network element sends an indication message to the NWDAF network element through the N23 interface. After receiving the indication message, the NWDAF network element will intelligently execute and control the designated services of the target terminal in the effective area based on the indication message and pre-configured designated service rules.

[0175] When the target terminal leaves the effective area, the PCF network element can terminate or suspend the intelligent service process according to the operator's service policy.

[0176] In one embodiment, the method may further include: In the process of opening the designated service at the target terminal, the service information and / or effective area information of the designated service sent by the service support system is received.

[0177] Specifically, in the present invention, the business support system of the roaming network equipment can provide package information of the specified service, and synchronize the activation information of the specified service to the business support system of the network equipment in the relevant geographical area (such as province, city, etc.) that allows the contract of the specified service.

[0178] The activation information covers the basic package information of the designated service (such as the designated service ID, etc.) and the effective area information of the designated service. The effective area information includes the designated service development area, the geographical area supported by the service, etc., such as "xx Province-Airport", "xx Province-XX Scenic Area", etc.

[0179] The service support system of the terminal's home network device can accept or reject the opening of the designated service to the terminal in this geographical area according to local management requirements and network conditions. If rejected, a rejection message is sent to the service support system of the roaming network device. When the terminal in this geographical area roams to the designated service provision area, the terminal can be prompted by SMS or other means that its home area does not currently support the opening of the designated roaming service.

[0180] If the business support system of the terminal's network device accepts the designated service and provides it to the local terminal, when the terminal applies for activation of the designated service, the business support system of the terminal's network device is activated to the terminal's contracted node, such as a PCF network element, and carries the service information and the corresponding effective area information of the service.

[0181] Specifically, Figure 5 Taking an example as an example, the service implementation method provided by the present invention may further include: Step 501, service activation: according to the above-mentioned designated service activation process, the target terminal activates the designated service of the roaming area in the home area, including signing a roaming service contract with the PCF network element, which carries information such as service information and / or effective area.

[0183] Step 503: The SMF network element establishes a connection with the PCF network element.

[0184] After the target terminal completes the basic session establishment process, an N7 interface link can be implemented between the SMF network element and the PCF network element, wherein the PCC process can refer to the prior art and will not be described in detail in the present invention.

[0185] After completing step 503, the above step 510 may be entered.

[0186] In one embodiment, the specified service may be any of the following: Only used for services in the effective area of ​​the above roaming location; Used for services in different roaming areas.

[0187] It is understandable that when a designated service is a service used only in an effective area of ​​a certain roaming location, it can still be signed and promoted for use to users across the entire network.

[0188] When the designated service is a service used in effective areas of different roaming locations, the identifier of the designated service may be uniformly planned for the entire network.

[0189] Specifically, when the specified service can be implemented in the effective area of ​​the entire network, the service information (such as the service ID of the unified planning) of the entire network can be configured for the specified service in the service activation process. Figure 5 In steps S501, S510 and other steps, only the service information of the unified planning of the whole network needs to be exchanged.

[0190] Figure 7 This is the fifth flow chart of the service implementation method provided by the present invention. Figure 7 As shown, the service implementation method provided by the present invention is applied to a first network device, and the method may include: Step 710: Receive the effective area information sent by the second network device, and convert the effective area information into network side location information; Step 720: Send the network-side location information of the effective area to the session anchor network device of the target terminal; Step 730: Receive a network side location subscription message of the target terminal, and determine the real-time network side location information of the target terminal based on the network side location subscription message; the network side location subscription message is generated by the second network device; Step 740: Synchronize the real-time network side location information to the second network device; The first network device is a roaming network device of the target terminal, and the second network device is a home network device of the target terminal; The network side location information of the effective area and the real-time network side location information are used to determine the designated service of the target terminal in the effective area; The effective area information is determined when the target terminal activates the specified service.

[0191] Before step 710, the second network device may obtain the current access location information (such as AMF ID, GUAMI, etc.) of the target terminal from the first network device, and determine whether the target terminal is located in a roaming area providing the specified service in combination with the pre-acquired effective area information.

[0192] If yes, the second network device will send a trigger message (eg, trigger) to the first network device to obtain a notification of the target terminal entering or exiting the effective area, wherein the trigger message includes effective area information.

[0193] If not, the second network device will not send a trigger message to the first network device.

[0194] Among them, the effective area information may include the region / province where the designated business is carried out and the geographical area information supported by the business, such as "XX Airport in XX Province", "XX Scenic Area in XX City", etc.

[0195] Designated services may include various types of voice services and data services, such as displaying a specific LOGO, providing specific voice services (scenic spot guides, venue precautions, etc.), providing short video services with specific content, etc.

[0196] In step 710, the first network device receives the trigger message and obtains the effective area information from the trigger message. Then, the first network device converts the effective area information into network side location information (such as PRA and TAI list corresponding to the effective area).

[0197] In step 720, the first network device sends the converted network side location information of the effective area to the session anchor network device of the target terminal, and the session anchor network device sends the network side location information of the effective area to the second network device.

[0198] The second network device will send a network side location subscription message to the session anchor point based on the network side location information of the effective area to subscribe to the network side location information of the target terminal; alternatively, the second network device may also send a network side location subscription message directly to the first network device based on the network side location information of the effective area.

[0199] In step 730, the first network device may receive a network-side location subscription message of the target terminal from the session anchor network device or the second network device, and determine the real-time network-side location information of the target terminal based on the network-side location subscription message.

[0200] Next, in step 740, the first network device may send the real-time network side location information of the target terminal to the session anchor network device, and the session anchor network device may send the real-time network side location information to the second network device.

[0201] Alternatively, the first network device may directly send the real-time network-side location information of the target terminal to the second network device.

[0202] The second network device determines whether the target terminal enters the effective area based on the network side location information of the effective area and the real-time network side location information.

[0203] If the target terminal enters the effective area, the second network device will execute the designated service of the target terminal in the effective area.

[0204] If the target terminal leaves the effective area, the second network device will terminate or suspend the execution of the designated service of the target terminal in the effective area.

[0205] The service implementation method provided by the present invention can avoid pre-configuring the network side location information of all different service effective areas in the roaming area at the terminal's home location by triggering the target terminal's home network device to initiate the execution of the specified service in the effective area when the target terminal enters the effective area of ​​the roaming area, thereby simplifying the process of executing the specified service in the effective area of ​​the roaming area and improving the feasibility of service implementation.

[0206] In one embodiment, the method may further include: An indication message sent by the second network device is received, and a designated service of the target terminal in the effective area is executed based on the indication message.

[0207] It should be noted that in addition to directly executing the designated service by the second network device based on the network side location information and real-time network side location information of the effective area, the second network device can also send an indication message to the first network device after receiving the network side location information and real-time network side location information of the effective area to determine that the target terminal has entered the effective area, and the first network device will execute the designated service of the target terminal in the effective area based on the indication message.

[0208] The service implementation method provided by the present invention effectively expands the service scenarios because both the first network device and the second network device can execute the designated service of the target terminal in the effective area.

[0209] In one embodiment, in order to specifically adapt to the scenario based on the SM POLICY service, the first network device may include a roaming SMF network element and an AMF network element; the second network device may include a PCF network element; the session anchor network device may include a session anchor SMF network element; the method may specifically include: The roaming SMF network element receives the effective area information sent by the PCF network element and converts the effective area information into network side location information; The roaming SMF network element sends the network side location information of the effective area to the session anchor SMF network element; The roaming SMF network element receives the network side location subscription message of the target terminal, and the AMF network element determines the real-time network side location information of the target terminal based on the network side location subscription message; The roaming SMF network element synchronizes the real-time network location information to the PCF network element.

[0210] like Figure 8 As shown, in this embodiment, the workflow of the above network elements may be as follows: Step 810: The PCF network element determines whether the target terminal is currently in a roaming location (such as a province, city, etc.) that provides the specified service based on the location information in the effective area information and the current access location information of the target terminal obtained through the N7 interface (such as AMF ID, GUAMI, etc.).

[0211] If so, the PCF network element sends a trigger message to the N7 interface message of the roaming SMF network element to obtain notification of the target terminal entering or leaving the effective area, where the trigger message includes effective area information (such as "airport", etc.).

[0212] If not, the PCF network element does not send a trigger message.

[0213] Step 820: The roaming SMF network element converts the effective area information obtained from the N7 interface into network side location information (such as the PRA and TAI list corresponding to the effective area), and feeds back the network side location information to the PCF network element.

[0214] It should be noted that for the scenario where the target terminal mobile handover involves inserting an I-SMF network element in the roaming location, the following methods can be adopted according to the operator's policy: Solution 1: The PCF network element triggers session reestablishment in the roaming location based on the target terminal location. The subsequent process is the same as the process without I-SMF scenario, such as the above Figure 5 process.

[0215] Solution 2: The I-SMF network element or AMF network element of the first network device (roaming location) pre-configures the network side location information of the effective area and continues with subsequent steps.

[0216] Step 830: The roaming SMF network element (I-SMF network element) or the AMF network element sends the network side location information of the effective area to the session anchor SMF network element.

[0217] Step 840: The session anchor SMF network element sends the network side location information of the effective area to the PCF network element.

[0218] Step 850: The PCF network element sends a network side location subscription message (PRA subscription) of the target terminal to the session anchor SMF network element based on the received network side location information to subscribe to the real-time network side location information of the target terminal.

[0219] Alternatively, execute step 850', the PCF network element initiates a PRA subscription to the AMF network element through the roaming SMF network element (via the I-SMF network element).

[0220] Among them, the PCF network element can determine the specific type of the network side location subscription message of the target terminal based on the following business logic: If the received data is PRA and the corresponding TAI LIST, the PCF network element sends the PRA subscription (including PRA and the corresponding TAI list); If the received ID is a PRA ID, the PCF network element sends the PRA subscription (the TAI list corresponding to the specific PRA needs to be configured on the AMF network element); If the received information is a TAI list, the PCF network element sends a TAC location subscription.

[0221] Step 860: The roaming SMF network element sends the real-time network location information to the session anchor SMF network element, and the session anchor SMF network element then sends the real-time network location information to the PCF network element.

[0222] Alternatively, execute step 860', the roaming SMF network element (via the I-SMF network element) sends the real-time network location information to the PCF network element.

[0223] Step 870: The PCF network element determines whether the target terminal enters the effective area based on the acquired network side location information of the effective area and the real-time network side location information to execute specific service logic: When the target terminal enters the effective area, the PCF network element executes the designated service of the target terminal in the effective area based on the relevant SM POLICY; when the target terminal leaves the effective area, the PCF network element terminates or suspends the designated service execution. When the target terminal session ends, the designated service process terminates.

[0224] In one embodiment, the first network device may further include a NWDAF network element, and the method may further include: The NWDAF network element receives the indication message sent by the PCF network element, and executes the designated service of the target terminal in the effective area based on the indication message.

[0225] Still Figure 8 For example, when the first network device includes a NWDAF network element, the method may further include the following steps: Step 870', the PCF network element implements intelligent service triggering based on the information of the target terminal entering and exiting the effective area reported by the SMF network element: When the target terminal enters the effective area, the PCF network element sends an indication message to the NWDAF network element. After receiving the indication message, the NWDAF network element intelligently executes and controls the designated services of the target terminal in the effective area based on the indication message and pre-configured designated service rules.

[0226] When the target terminal leaves the effective area, the PCF network element can terminate or suspend the intelligent service process according to the operator's service policy.

[0227] Optionally, in combination with the implementation of a specific intelligent service processing flow, the PCF network element can simultaneously carry the corresponding service information (such as service ID, etc.) and the network side location information corresponding to the corresponding effective area when initiating the service subscription process between the PCF network element and the intelligent service node NWDAF network element. The NWDAF network element can control the intelligent service process based on the effective area information.

[0228] In one embodiment, before receiving the effective area information sent by the second network device, the method may further include: The network-side location information of the pre-configured effective area.

[0229] Specifically, in the present invention, the business support system in the roaming area can provide package information of the designated service, and synchronize the activation information of the designated service to the business support system of the relevant geographical area (such as province, city, etc.) that allows the contract of the designated service.

[0230] The activation information covers the basic package information of the designated service (such as the designated service ID, etc.) and the effective area information of the designated service. The effective area information includes the designated service development area, the geographical area supported by the service, etc., such as "xx Province-Airport", "xx Province-XX Scenic Area", etc.

[0231] The service support system at the terminal's home location can accept or reject the opening of the designated service to the terminal in this geographical area according to local management requirements and network conditions. If rejected, a rejection message will be sent to the service support system at the roaming location. When the terminal in this geographical area roams to the area where the designated service is provided, the terminal can be prompted by SMS or other means that its home location does not currently support the opening of the designated roaming service.

[0232] If the business support system at the terminal's location accepts the designated service and provides it to the local terminal, when the terminal applies to activate the designated service, the business support system of the terminal's network device will be activated to the terminal's contracted node, such as a PCF network element, and carry the service information and / or the effective area information of the service.

[0233] Specifically, Figure 8 Taking an example as an example, the service implementation method provided by the present invention may further include: Step 801, service activation: according to the above-mentioned designated service activation process, the target terminal activates the designated service of the roaming area in the home area, including signing a roaming service contract with the PCF network element, which carries information such as service information and / or effective area.

[0234] Step 802, pre-configuration requirement: the roaming SMF network element or AMF network element pre-configures the network side location information of the local effective area corresponding to the specified service (such as the PRA or TAI list information corresponding to the "airport", etc.).

[0235] Step 803: The roaming SMF network element establishes a connection with the PCF network element.

[0236] After the target terminal completes the basic session establishment process, the N7 interface link can be realized between the roaming SMF network element and the PCF network element, wherein the PCC process can refer to the prior art and will not be described in detail in the present invention.

[0237] After completing step 803, the above step 810 may be entered.

[0238] In one embodiment, the specified service may be any of the following: Only used for services in the effective area of ​​the above roaming location; Used for services in different roaming areas.

[0239] It is understandable that when a designated service is a service used only in an effective area of ​​a certain roaming location, it can still be signed and promoted for use to users across the entire network.

[0240] When the designated service is a service used in effective areas of different roaming locations, the identifier of the designated service may be uniformly planned for the entire network.

[0241] Specifically, when the specified service can be implemented in the effective area of ​​the entire network, the service information (such as the service ID of the unified planning) of the entire network can be configured for the specified service in the service activation process. Figure 5 In steps S801, S810 and other steps, only the service information of the unified planning of the whole network needs to be exchanged.

[0242] Fig. 9 This is the sixth flow chart of the service implementation method provided by the present invention. Fig. 9 As shown, the service implementation method provided by the present invention is applied to the second network device, and the method may include: Step 910: Acquire location information of a target terminal from a first network device; Step 920: When it is determined that the target terminal is located in a roaming area where the designated service is provided, the effective area information is sent to the first network device; Step 930: Receive network-side location information of the effective area from the session anchor network device of the target terminal; Step 940: Send a network side location subscription message of the target terminal to the session anchor network device, and obtain the real-time network side location information of the target terminal; the network side location subscription message is used to subscribe to the real-time network side location information of the target terminal; Step 950: When it is determined that the target terminal has entered the effective area based on the network side location information of the effective area and the real-time network side location information, execute the designated service of the target terminal in the effective area; The first network device is a roaming network device of the target terminal, and the second network device is a home network device of the target terminal; The effective area information is determined when the target terminal activates the specified service.

[0243] In step 910, the second network device may obtain the current access location information (such as AMF ID, GUAMI, etc.) of the target terminal from the first network device.

[0244] In step 920, the second network device may determine whether the target terminal is located in a roaming area providing a designated service based on the current access location information of the target terminal and the pre-acquired effective area information.

[0245] If yes, the second network device will send a trigger message (eg, trigger) to the first network device to obtain a notification of the target terminal entering or exiting the effective area, wherein the trigger message includes effective area information.

[0246] If not, the second network device will not send a trigger message to the first network device.

[0247] Among them, the effective area information may include the region / province where the designated business is carried out and the geographical area information supported by the business, such as "XX Airport in XX Province", "XX Scenic Area in XX City", etc.

[0248] Designated services may include various types of voice services and data services, such as displaying a specific LOGO, providing specific voice services (scenic spot guides, venue precautions, etc.), providing short video services with specific content, etc.

[0249] In step 930, the first network device receives the trigger message and obtains the effective area information from the trigger message. Then, the first network device converts the effective area information into network side location information (such as the PRA and TAI list corresponding to the effective area).

[0250] The first network device will send the converted network side location information of the effective area to the session anchor network device of the target terminal, and the session anchor network device will send the network side location information of the effective area to the second network device.

[0251] In step 940, the second network device will send a network side location subscription message to the session anchor point based on the network side location information of the effective area to subscribe to the network side location information of the target terminal; alternatively, the second network device may also send a network side location subscription message directly to the first network device based on the network side location information of the effective area.

[0252] The first network device may receive a network-side location subscription message of the target terminal from the session anchor network device or the second network device, and determine the real-time network-side location information of the target terminal based on the network-side location subscription message.

[0253] Then, the first network device may send the real-time network-side location information of the target terminal to the session anchor network device, and the session anchor network device may send the real-time network-side location information to the second network device.

[0254] Alternatively, the first network device may directly send the real-time network-side location information of the target terminal to the second network device.

[0255] In step 950, the second network device determines whether the target terminal enters the effective area based on the network side location information of the effective area and the real-time network side location information.

[0256] If the target terminal enters the effective area, the second network device will execute the designated service of the target terminal in the effective area.

[0257] If the target terminal leaves the effective area, the second network device will terminate or suspend the execution of the designated service of the target terminal in the effective area.

[0258] The service implementation method provided by the present invention can avoid pre-configuring the network side location information of all different service effective areas in the roaming area at the terminal's home location by triggering the target terminal's home network device to initiate the execution of the specified service in the effective area when the target terminal enters the effective area of ​​the roaming area, thereby simplifying the process of executing the specified service in the effective area of ​​the roaming area and improving the feasibility of service implementation.

[0259] In one embodiment, executing the designated service of the target terminal in the effective area may include: An instruction message is sent to the first network device, where the instruction message is used to execute a designated service of the target terminal in the effective area.

[0260] It should be noted that in addition to directly executing the designated service by the second network device based on the network side location information and real-time network side location information of the effective area, the second network device can also send an indication message to the first network device after receiving the network side location information and real-time network side location information of the effective area to determine that the target terminal has entered the effective area, and the first network device will execute the designated service of the target terminal in the effective area based on the indication message.

[0261] The service implementation method provided by the present invention effectively expands the service scenarios because both the first network device and the second network device can execute the designated service of the target terminal in the effective area.

[0262] In one embodiment, in order to specifically adapt to the scenario based on the SM POLICY service, the second network device may include a PCF network element; the first network device may include a roaming SMF network element and an AMF network element; the session anchor network device may include a session anchor SMF network element; the method may specifically include: The PCF network element obtains the location information of the target terminal from the AMF network element; When it is determined that the target terminal is located in a roaming location where the specified service is provided, the PCF network element sends the effective area information to the roaming SMF network element; The PCF network element receives the network side location information of the effective area from the session anchor SMF network element; The PCF network element sends a network-side location subscription message of the target terminal to the session anchor SMF network element, and obtains the real-time network-side location information of the target terminal; When it is determined that the target terminal enters the effective area, the PCF network element executes the designated service of the target terminal in the effective area.

[0263] like Figure 8 As shown, in this embodiment, the workflow of the above network elements may be as follows: Step 810: The PCF network element determines whether the target terminal is currently in a roaming location (such as a province, city, etc.) that provides the specified service based on the location information in the effective area information and the current access location information of the target terminal obtained through the N7 interface (such as AMF ID, GUAMI, etc.).

[0264] If so, the PCF network element sends a trigger message to the N7 interface message of the roaming SMF network element to obtain notification of the target terminal entering or leaving the effective area, where the trigger message includes effective area information (such as "airport", etc.).

[0265] If not, the PCF network element does not send a trigger message.

[0266] Step 820: The roaming SMF network element converts the effective area information obtained from the N7 interface into network side location information (such as the PRA and TAI list corresponding to the effective area), and feeds back the network side location information to the PCF network element.

[0267] It should be noted that for the scenario where the target terminal mobile handover involves inserting an I-SMF network element in the roaming location, the following methods can be adopted according to the operator's policy: Solution 1: The PCF network element triggers session reestablishment in the roaming location based on the target terminal location. The subsequent process is the same as the process without I-SMF scenario, such as the above Figure 5 process.

[0268] Solution 2: The I-SMF network element or AMF network element of the first network device (roaming location) pre-configures the network side location information of the effective area and continues with subsequent steps.

[0269] Step 830: The roaming SMF network element (I-SMF network element) or the AMF network element sends the network side location information of the effective area to the session anchor SMF network element.

[0270] Step 840: The session anchor SMF network element sends the network side location information of the effective area to the PCF network element.

[0271] Step 850: The PCF network element sends a network side location subscription message (PRA subscription) of the target terminal to the session anchor SMF network element based on the received network side location information to subscribe to the real-time network side location information of the target terminal.

[0272] Alternatively, execute step 850', the PCF network element initiates a PRA subscription to the AMF network element through the roaming SMF network element (via the I-SMF network element).

[0273] Among them, the PCF network element can determine the specific type of the network side location subscription message of the target terminal based on the following business logic: If the received data is PRA and the corresponding TAI LIST, the PCF network element sends the PRA subscription (including PRA and the corresponding TAI list); If the received ID is a PRA ID, the PCF network element sends the PRA subscription (the TAI list corresponding to the specific PRA needs to be configured on the AMF network element); If the received information is a TAI list, the PCF network element sends a TAC location subscription.

[0274] Step 860: The roaming SMF network element sends the real-time network location information to the session anchor SMF network element, and the session anchor SMF network element then sends the real-time network location information to the PCF network element.

[0275] Alternatively, execute step 860', the roaming SMF network element (via the I-SMF network element) sends the real-time network location information to the PCF network element.

[0276] Step 870: The PCF network element determines whether the target terminal enters the effective area based on the acquired network side location information of the effective area and the real-time network side location information to execute specific service logic: When the target terminal enters the effective area, the PCF network element executes the designated service of the target terminal in the effective area based on the relevant SM POLICY; when the target terminal leaves the effective area, the PCF network element terminates or suspends the designated service execution. When the target terminal session ends, the designated service process terminates.

[0277] In one embodiment, the first network device may further include a NWDAF network element, and the method may further include: The PCF network element sends indication information to the NWDAF network element.

[0278] Still Figure 8 For example, when the first network device includes a NWDAF network element, the method may further include the following steps: Step 870', the PCF network element implements intelligent service triggering based on the information of the target terminal entering and exiting the effective area reported by the SMF network element: When the target terminal enters the effective area, the PCF network element sends an indication message to the NWDAF network element. After receiving the indication message, the NWDAF network element intelligently executes and controls the designated services of the target terminal in the effective area based on the indication message and pre-configured designated service rules.

[0279] When the target terminal leaves the effective area, the PCF network element can terminate or suspend the intelligent service process according to the operator's service policy.

[0280] Optionally, in combination with the implementation of a specific intelligent service processing flow, the PCF network element can simultaneously carry the corresponding service information (such as service ID, etc.) and the network side location information corresponding to the corresponding effective area when initiating the service subscription process between the PCF network element and the intelligent service node NWDAF network element. The NWDAF network element can control the intelligent service process based on the effective area information.

[0281] In one embodiment, the method may further include: In the process of opening the designated service at the target terminal, the service information and / or effective area information of the designated service sent by the service support system is received.

[0282] Specifically, in the present invention, the business support system in the roaming area can provide package information of the designated service, and synchronize the activation information of the designated service to the business support system of the relevant geographical area (such as province, city, etc.) that allows the contract of the designated service.

[0283] The activation information covers the basic package information of the designated service (such as the designated service ID, etc.) and the effective area information of the designated service. The effective area information includes the designated service development area, the geographical area supported by the service, etc., such as "xx Province-Airport", "xx Province-XX Scenic Area", etc.

[0284] The service support system at the terminal's home location can accept or reject the opening of the designated service to the terminal in this geographical area according to local management requirements and network conditions. If rejected, a rejection message will be sent to the service support system at the roaming location. When the terminal in this geographical area roams to the area where the designated service is provided, the terminal can be prompted by SMS or other means that its home location does not currently support the opening of the designated roaming service.

[0285] If the business support system at the terminal's location accepts the designated service and provides it to the local terminal, when the terminal applies to activate the designated service, the business support system of the terminal's network device will be activated to the terminal's contracted node, such as a PCF network element, and carry the service information and / or the effective area information of the service.

[0286] Specifically, Figure 8 Taking an example as an example, the service implementation method provided by the present invention may further include: Step 801, service activation: according to the above-mentioned designated service activation process, the target terminal activates the designated service of the roaming area in the home area, including signing a roaming service contract with the PCF network element, which carries information such as service information and / or effective area.

[0287] Step 802, pre-configuration requirement: the roaming SMF network element or AMF network element pre-configures the network side location information of the local effective area corresponding to the specified service (such as the PRA or TAI list information corresponding to the "airport", etc.).

[0288] Step 803: The roaming SMF network element establishes a connection with the PCF network element.

[0289] After the target terminal completes the basic session establishment process, the N7 interface link can be realized between the roaming SMF network element and the PCF network element, wherein the PCC process can refer to the prior art and will not be described in detail in the present invention.

[0290] After completing step 803, the above step 810 may be entered.

[0291] In one embodiment, the specified service may be any of the following: Only used for services in the effective area of ​​the above roaming location; Used for services in different roaming areas.

[0292] It is understandable that when a designated service is a service used only in an effective area of ​​a certain roaming location, it can still be signed and promoted for use to users across the entire network.

[0293] When the designated service is a service used in effective areas of different roaming locations, the identifier of the designated service may be uniformly planned for the entire network.

[0294] Specifically, when the specified service can be implemented in the effective area of ​​the entire network, the service information (such as the service ID of the unified planning) of the entire network can be configured for the specified service in the service activation process. Figure 5 In steps S801, S810 and other steps, only the service information of the unified planning of the whole network needs to be exchanged.

[0295] The service implementation methods described in the above embodiments of the present invention may also be applied to the following scenarios: Scenario 1: Local featured services are enabled in roaming areas, but the effective area is not a fixed area. That is, the service activation data can only provide the service name, such as "xx featured service in xx province".

[0296] Scenario 2: The terminal signs a network-wide service in the home location, but the scope of the service provided in various places is not fixed. That is, the service activation data only contains unified service information planned for the entire network (such as service ID, etc.), such as "xx service (such as short video)". However, the service needs to be triggered and controlled based on the scope of the service provided in the local area in the roaming location.

[0297] For the above scenario, based on the solution described in this proposal, the "Effective Area" field information can be replaced with "XX Province XX Featured Service" (corresponding to the above scenario 1) or the "xx service" (corresponding to the above scenario 2) uniformly planned for the entire network. Similarly, the corresponding service control can be achieved by configuring the network-side location information corresponding to the local "xx featured service" or "xx service" in the roaming area, thereby realizing service implementation when the service provision area is not fixed, without the need to pre-configure the network-side location information corresponding to the corresponding service of the entire network at the terminal's home node and update it in real time.

[0298] In addition, considering that the "effective area" and "xx business" may be temporarily planned according to business development, or the business area may be dynamically adjusted, the relevant parsing data may also be shared by multiple nodes. Therefore, in order to ensure data consistency and simplify the configuration requirements of related nodes, it is possible to consider using a unified data storage function to realize the parsing data storage of local related "effective area" and "xx business" and the network side location area. When the network side obtains the "effective area" and "xx business" information, it can go to the unified database to convert the network side location area information and then perform subsequent business processing.

[0299] Fig.10 This is one of the structural diagrams of the service implementation device provided by the present invention. Fig.10 As shown, the present invention provides a service implementation device, which is applied to a first network device, and the device may include: An acquisition module 1010 is used to acquire service information and / or effective area information of a specified service from the second network device; An execution module 1020 is configured to execute a designated service for the target terminal in the effective area based on the service information when it is determined that the target terminal enters an effective area corresponding to the roaming location; The first network device is a roaming network device of the target terminal, and the second network device is a home network device of the target terminal; the service information and effective area information are determined when the target terminal activates the designated service.
