Description

Background Art

[0002] With the continuous development of mobile communication technology, 5G (5th generation mobile networks) networks, with their ultra-high speed, ultra-low latency and massive connections, are gradually penetrating into all walks of life, promoting the accelerated development of social informatization.

Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0064] The specific implementation of the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.

[0065] Figure 1 FIG. 1 shows an exemplary application system architecture diagram to which the information transmission method in the embodiment of the present disclosure can be applied. Figure 1 As shown, the system architecture 100 may include a target network element 101 , a network 102 , and a UDM network element 103 .

[0066] The target network element 101 may send a user subscription data request message to the UDM network element 103. Then, the UDM network element 103 may obtain the user subscription data request message sent by the target network element 101.

[0067] Then, the UDM network element 103 may determine the location information of the target user according to the user subscription data request message, and may determine the subscription DNN of the target user according to the location information of the target user.

[0068] Finally, the UDM network element 103 may send the contracted DNN to the target network element 101 , where the contracted DNN is used to implement user service management based on location information.

[0069] The network 102 is a medium used to provide a communication link between the target network element 101 and the UDM network element 103, and may be a wired network or a wireless network.

[0070] Optionally, the wireless network or wired network described above uses standard communication technology and / or protocols. The network is typically the Internet, but may also be any network, including but not limited to a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile, wired or wireless network, a private network or any combination of a virtual private network). In some embodiments, technologies and / or formats including Hyper Text Mark-up Language (HTML), Extensible Markup Language (XML), etc. are used to represent data exchanged over the network. In addition, conventional encryption technologies such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), Internet Protocol Security (IPSec), etc. may be used to encrypt all or some links. In other embodiments, customized and / or dedicated data communication technologies may also be used to replace or supplement the above data communication technologies.

[0071] Those skilled in the art will know that Figure 1 The number of target network elements 101, networks 102 and UDM network elements 103 is only illustrative, and any number of target network elements 101, networks 102 and UDM network elements 103 may be provided according to actual needs. This is not limited in the embodiments of the present disclosure.

[0072] Under the above system architecture, an information transmission method is provided in an embodiment of the present disclosure, and the method can be executed by any electronic device with computing and processing capabilities.

[0073] In some embodiments, the information transmission method provided in the embodiments of the present disclosure may be executed by the UDM network element of the above system architecture. In other embodiments, the information transmission method provided in the embodiments of the present disclosure may be executed by the UDM network element in the above system architecture and the target network element in an interactive manner.

[0074] Figure 2 A flow chart of an information transmission method in an embodiment of the present disclosure is shown as follows: Figure 2 As shown, the information transmission method provided in the embodiment of the present disclosure includes the following steps S202 to S208.

[0075] S202: The UDM network element obtains a user subscription data request message sent by a target network element.

[0076] The disclosed embodiment does not limit the target network element, and the target network element can be determined according to the application scenario or experience. For example, the target network element can be any network element that needs to perform policy control on the service subscribed by the target user according to the target user's contract data. For example, the target network element can be an SMF network element, an AMF network element, etc.

[0077] The disclosed embodiment also does not limit the conditions for the target network element to send the user subscription data request message. For example, the target network element may send the user subscription data request message during the process of the target user going online, or may send the user subscription data request message during the process of establishing a target user session.

[0078] Exemplarily, the user subscription data request message may be included in a user registration request message of the target user. Alternatively, the user subscription data request message may be included in a session establishment request message of the target user.

[0079] In some exemplary embodiments, the information transmission method provided by the embodiments of the present disclosure may further include: obtaining a user location information mapping table, where the user location information mapping table is used to describe the mapping relationship between each location information and the contracted DNN.

[0080] Exemplarily, the user location information mapping table may be pre-configured in the UDM network element. Alternatively, the UDM network element may obtain the user location information mapping table from a device storing the user location information mapping table. The user location information mapping table may include multiple location information, and each location information corresponds to a contracted DNN.

[0081] It should be noted that, since customized network services may require users to use different service strategies in different location areas, the embodiment of the present disclosure can determine the contracted DNN corresponding to each location information based on the user location information mapping table, and differentiated control requirements for different location areas can be achieved by contracting DNNs corresponding to each user.

[0082] S204: The UDM network element determines the location information of the target user according to the user subscription data request message.

[0083] In some possible implementations, the target user may be a user who has subscribed to a specified service. Exemplarily, the specified service may be a service that needs to be differentially controlled according to user location information.

[0084] Therefore, when the target user subscribes to the designated service, the UDM network element can read the location information of the target user after obtaining the user subscription data request message corresponding to the target user.

[0085] In some exemplary embodiments, determining the location information of the target user based on the user subscription data request message includes: determining whether the user subscription data request message contains a target service tag; when the target service tag is contained, determining the location information corresponding to the target user.

[0086] In an exemplary embodiment, when the target user subscribes to a designated service, the UDM network element may tag the user with a target service label. The user subscription data request message corresponding to the target user may include the target service label.

[0087] Therefore, when the UDM network element recognizes the target service tag in the user subscription data request message, the location information corresponding to the target user can be determined. When the UDM network element does not recognize the target service tag in the user subscription data request message, the target user has not subscribed to the specified service, so there is no need to determine the location information.

[0088] In a possible implementation, a judgment and processing module for specifying customized network services can be added to the UDM network element in advance. The UDM network element can implement a target service label for the target user through the judgment and processing module. The target service label in the user contract data request message can also be identified through the judgment and processing module.

[0089] In some exemplary embodiments, determining the location information of the target user based on the user subscription data request message may include: obtaining an instance identifier from the subscription data request message; and determining the location information based on the instance identifier, wherein the location information is used to describe the current location of the target user.

[0090] In a possible implementation, the instance identifier may be NFinstanceID (Network Function Instance Identifier).

[0091] It should be noted that in the 5G network architecture, NFInstanceID is used to uniquely identify a specific network function instance. Each network function instance has a unique NFInstanceID for identification and management in the network.

[0092] Since the service of each network function instance covers a certain range, the location information of the target user can be determined based on the nfinstanceID of the network function instance, and the granularity of the location information can depend on the network planning. For example, the AMF network element can select the SMF network element that serves the user based on the TAC (Tracking Area Code), then the NFinstanceID of the corresponding SMF network element can describe the location of its user as the range of the corresponding TAC.

[0093] In an exemplary embodiment, the user subscription data request message may include a target service tag and NFInstanceID. When the UDM network element identifies the target service tag, the current location of the target user can be determined according to the NFInstanceID in the user subscription data request message.

[0094] In some exemplary embodiments, the instance identifier may be used as location information of the target user.

[0095] Alternatively, the location information may be divided based on regions. After the UDM network element obtains the instance identifier, it may determine the location region to which the current location of the target user belongs, thereby using the location region as the location information of the target user.

[0096] In another possible implementation, the subscription data request message may also include other types of information that can describe the current location of the user. The UDM network element may determine the location information of the target user based on the information. This disclosure embodiment is not limited to this.

[0097] S206: The UDM network element determines the contracted DNN of the target user according to the location information of the target user.

[0098] In some exemplary embodiments, determining the contracted DNN of the target user according to the location information of the target user includes: determining the contracted DNN of the target user from a user location mapping table according to the location information of the target user.

[0099] In an exemplary embodiment, the location information may be represented based on the instance identifier. Therefore, the user location mapping table may describe the corresponding relationship between the instance identifier and the contracted DNN.

[0100] Alternatively, the location information may be represented based on the location area. Therefore, the user location mapping table may describe the correspondence between the instance identifier, the location area, and the contracted DNN. It should be noted that any location area may correspond to at least one instance identifier. Any instance identifier may also correspond to at least one location area. Any contracted DNN may correspond to at least one location area.

[0101] For example, Figure 3 A schematic diagram showing the correspondence between an instance identifier, a location area and a contracted DNN provided in an embodiment of the present disclosure is shown.

[0102] In this Figure 3 In , instance identifier 1 corresponds to location area 1. Instance identifier 2 can correspond to location area 1 or location area 2. Location area 1 corresponds to contracted DNN 1, and location area 2 corresponds to contracted DNN 2.

[0103] Need to explain yes, Figure 3 For example, instance identifier 2 can correspond to either contracted DNN1 or contracted DNN2, so the UDM network element can return either contracted DNN1 or contracted DNN2 to the target network element. Alternatively, the UDM network element can filter contracted DNN1 and contracted DNN2 according to preset conditions. The preset conditions can be determined based on experience or application scenarios, and the embodiments of the present disclosure do not limit this.

[0104] In some exemplary embodiments, determining the contracted DNN of the target user according to the location information of the target user includes: determining contracted attribute information of the target user according to the location information of the target user, the contracted attribute information including the contracted DNN.

[0105] In an exemplary embodiment, in addition to the contracted DNN, the target user may also include other contract information, such as user identity information, service rights, security information, billing information, etc. The disclosed embodiment does not limit the contract attribute information, and the contract attribute information may include the above-mentioned various contract information and contracted DNN.

[0106] Therefore, according to the user subscription data request message sent by the target network element, the subscription attribute information can be returned to the target network element.

[0107] S208, the UDM network element sends the contracted DNN to the target network element, where the contracted DNN is used to implement user service management based on location information.

[0108] In some exemplary embodiments, sending the contract DNN to the target network element may include: sending the contract attribute information to the target network element. Exemplarily, the contract attribute information may include at least one contract information such as user identity information, service authority, security information, and billing information in addition to the contract DNN.

[0109] In some exemplary embodiments, the target network element may include an AMF network element.

[0110] In this case, sending the contract DNN to the target network element may include: sending the contract DNN to the AMF network element, wherein the AMF network element is used to perform user registration based on the contract DNN.

[0111] Exemplarily, when the target user who has subscribed to the specified service comes online, the AMF network element sends a user contract data request message to the UDM network element. The UDM network element determines that the target user has subscribed to the specified service, and then the UDM network element can determine the location information of the target user based on the NfinstanceID contained in the user contract data request message, and determine the contract DNN corresponding to the location information.

[0112] Finally, the UDM network element can return the contract DNN corresponding to the target user to the AMF network element. The AMF network element completes the subsequent user registration process based on the contract DNN and other contract information.

[0113] In some exemplary embodiments, the target network element may include an SMF network element.

[0114] In this case, sending the contracted DNN to the target network element may include: sending the contracted DNN to the SMF network element, wherein the SMF network element is used to establish a user session according to the contracted DNN.

[0115] For example, during the user session establishment phase, the SMF network element requests the user's contract attributes including the contract DNN from the UDM network element, and the UDM network element will also determine the location information of the target user based on the NfinstanceID, and determine the corresponding contract DNN based on the location information. Then, the UDM network element can return the contract DNN to the SMF network element.

[0116] Then, the SMF network element can complete the subsequent user session establishment according to the contracted DNN and other contract information. Thus, the disclosed embodiment can realize the service control of the target user based on the location area by the UDM network element issuing different contracted DNNs based on the location information of the target user.

[0117] The method provided by the embodiment of the present disclosure can determine the location information of the target user according to the user contract data request message, thereby determining the corresponding contract DNN according to the location information. Therefore, the embodiment of the present disclosure can manage user services based on location information, thereby realizing differentiated service control for different locations of the target user. In addition, the information transmission method simplifies the customized network service implementation logic and can promote the deployment of customized networks.

[0118] In an exemplary embodiment, a schematic diagram of an information transmission process provided by an embodiment of the present disclosure can be as follows: Figure 4 shown.

[0119] S402, target user goes online

[0120] S404, the AMF network element / SMF network element sends a user contract data request message to the UDM network element.

[0121] S406: The UDM network element determines whether the target user subscribes to the specified service.

[0122] If the UDM network element determines that the target user has not subscribed to the specified service, S408 is executed. If the UDM network element determines that the target user has subscribed to the specified service, S410 is executed.

[0123] S408, the UDM network element sends the default DNN.

[0124] It should be noted that the default DNN may be a DNN that does not change according to different location information.

[0125] S410, the UDM network element determines the location information of the target user.

[0126] S412, the UDM network element matches the contracted DNN according to the location information of the target user.

[0127] If the UDM network element determines that the location information of the target user is location area 1, S414 is executed. If the UDM network element determines that the location information of the target user is location area 2, S416 is executed.

[0128] S414, UDM network element sends the signed DNN1.

[0129] S416, UDM network element sends the signed DNN2.
