technical field

The application belongs to the technical field of communication, and in particular relates to a data service system.

Background technique

Network Data Analytics Function (NWDAF) is one of the network functions of the fifth-generation mobile communication (5th-Generation, 5G) core network control plane, and its functions are limited to the subscription provided by the 5G core network control plane network function events, and does not support the data collection of the core network user plane, radio access network and user equipment (User Equipment, UE). Moreover, the existing network does not yet support real-time data subscription and services. On the one hand, the interface performance and functional design do not support it. On the other hand, network element equipment does not consider this part of the overhead due to the unstandardized data service-related functions. Therefore, A large amount of real-time data reporting will affect network performance.

The Open-Radio Access Network (O-RAN) defines the real-time wireless intelligent controller as a network function, and its logical connection relationship is similar to the network management function. Moreover, the near real-time wireless intelligent controller currently focuses on data analysis applications on the network side, and cannot support data collection and analysis services for external functions of the network. Because the category belongs to the wireless side, UE-level data cannot support UE identity association of persistent data. In addition, the resources of the network equipment on the wireless side are more scarce, so the existing base station equipment cannot yet support reporting a large amount of near real-time or real-time data when the business load is high.

Facing network evolution, data such as measurement quantities required by various network functions may overlap, and adopting a chimney-style network function transparent transmission method similar to Location Management Function (LMF) may result in repeated reporting of measurement quantities. Moreover, services such as endogenous intelligence discussed in the sixth-generation mobile communication (6th-Generation, 6G) network are oriented to both network functions and external networks. Current technologies cannot solve cross-domain data security and service issues.

In order to describe the data service system provided by the embodiment of the present application more clearly, the data service structure will be described below in conjunction with three examples.

example one

As shown in FIG. 2 , the system includes a first function, and a data providing function or data consuming function connected to the first function through a first interface (identified as D1 in the figure). Data provision function or data consumption function includes application function, core network control plane (Core Network-Control Plane, CN-CP) function, core network user plane (Core Network-User Plane, CN-UP) function, wireless access network function , one or more of UE functions.

The first function is a core network data plane (Core Network-Data Plane, CN-DP) function, which is specifically used to perform at least one of the following:

1) The first function maintains contexts such as authorization information of data services according to predefined data level information and/or receiving operator and/or user-defined data level information.

2) When a data service request is received, based on the context information of the data service, authentication and other processing are performed to decide to accept, reject or modify the data service request. For example, the location management function LMF and the perception management function respectively request the measurement quantities required for positioning and perception from the first function.

3) For the accepted data service request, the first function processes the one or more service requests, including merging the same data service request, and mapping the data service request to one or more data providing functions (application function, core Network control plane functions, core network user plane functions, radio access network functions, UE functions) data collection information. For example, the above-mentioned measurement quantities required for positioning and sensing may both include received signal strength and angle of arrival, and the first function combines the above-mentioned same data requests, and decides that the data service requests are provided by the base station and/or UE.

4) Based on the mapping information, the first function is responsible for sending data acquisition control information, and/or data transmission channel control information, etc. to the corresponding data providing function. And/or, based on the mapping information, the first function is responsible for authorizing and controlling information to the data service requester and the data service provider, and based on the authorization and control information, the data service requester and the data service provider interact to complete the data service. For example, the above-mentioned measurement quantity data acquisition of LMF and perception is controlled by the first function, and the requested measurement quantity is received and sent to the LMF and perception management function. Compared with the existing LMF based on non-access stratum (Non-Access Stratum, NAS) signaling transparent transmission method, it avoids data requests being terminated in isolation on the LMF and the perception management function, and transparently transmitted through NAS signaling through AMF As a result, control information and measurement quantities are repeatedly interacted.

5) Based on the authorization and control information, receive the data sent by the data providing function. For example, the first function receives the above-mentioned request to collect data, and stores the received data according to the configuration information of the above-mentioned data classification.

6) Preprocessing the received data based on the decision information of the data service request, and providing it to the sender of the data service request. For example, the first function preprocesses the received measurement data (such as received signal strength and angle of arrival) or directly sends them to the LMF and the perception management function according to the data request information of the LMF and the perception management function. Or the first function notifies the LMF and the perception management function that the requested data is ready, and the LMF and the perception management function read the required data according to their own needs.

Optionally, when the UE acts as a data providing function or a data service consumer, a potential solution between the UE and the first function can be transparently transmitted through NAS, specifically including a similar session management (session management) message extension defining NAS messages, the The message is forwarded by the Access and Mobility Management Function (AMF) to the first function for processing, or a transport layer protocol is defined on the NAS similar to the positioning message, and NAS is one of the protocol layers.

Optionally, when the UE acts as a data providing function or a data service consumer, another potential solution for the UE and the first function is introduced into the data access layer (Data Access Stratum, DAS). The DAS message is terminated at the first function, so the above-mentioned data service interaction can directly reach the first function from the wireless access network, without forwarding by the existing core network control plane or data plane function. At the same time, this solution decouples the data plane function from the existing core network NAS functions, which facilitates the deployment of the first function and meets the needs of different scenarios.

Further, if the control information of the service is separated from the data information, then the data transmission scheme of a data service between the UE and the first function is similar to an IP Multimedia Subsystem (IP Multimedia Subsystem, IMS) establishing a terminal between the first function and the UE. End-to-end transmission channel. Another solution is to transmit data based on the transmission channel between the radio access network function node and the first function, the channel is a transmission channel based on each node (per node), and the data of different UEs is passed through UE identification and/or Subscription data identifier to distinguish. Or based on the transmission channel between the core network function node (such as User Plane Function (UPF)) and the first function to transmit data, the channel is a per node transmission channel, and the data of different UEs is passed through UE identification and / or subscription data identifier to distinguish.

Example two

As shown in Figure 3, this example provides a hierarchical data plane solution for the core network and radio access network, the system includes the first function and the second The interface (identified as D2 in the figure) is a data providing function or a data consuming function respectively connected to the first function and the second function. The data providing function or data consuming function connected to the first function includes one or more of an application function, a core network control plane function, a core network user plane function, a second function, and a UE function. The data providing function or data consuming function connected to the second function includes one or more of application functions, radio access network functions, and UE functions.

In this example, the first function provides data services that include end-to-end information (such as end-to-end delay, jitter, and bandwidth of mobile network transmission), and data services that do not require high real-time performance; the second function is based on the first The configuration information of a function provides the data service of the wireless access network and the data service with high real-time requirements, such as the air interface rate of each transmission time interval TTI of the air interface or the agreed time period (such as 10 TTI or 100 TTI) Air interface average speed. Therefore, considering the second function such as real-time factors, SCTP/IP, GTP-U/TCP/IP and other low-latency transmission protocols are preferred, as well as low-latency data serialization schemes and abstract syntaxes such as ASN.1 and Protobuf.

Among them, the relevant steps of the first function are briefly described as follows:

The first function maintains contexts such as authorization information of data services according to predefined data level information and/or data level information customized by receiving operators and/or users.

When a data service request is received, based on the context information of the displayed data service, authentication and other processing are performed to decide to accept, reject or modify the data service request.

For the accepted data service request, the first function processes the one or more service requests, including merging the same data service request, and mapping the data service request to one or more data providing functions (application function, core network control plane function, core network user plane function, second function, UE function) data collection information.

Based on the mapping information, if the second function is required to provide the data service, the first function authorizes the second function and the corresponding data service requester respectively. One potential implementation is to distribute authorization tokens (tokens) and indicate the time interval for which the tokens are valid.

Based on the mapping information, the first function is responsible for sending data collection control information, and/or data transmission channel control information, etc., with the corresponding data providing function.

Based on the control information, the received data provides the data sent by the function.

Based on the decision information of the data service request, the received data is preprocessed and provided to the sender of the data service request.

The second function may be the radio access network data plane (RAN-Data Plane, RAN-DP), and the relevant steps of the second function are briefly described as follows:

According to the configuration information of the first function, the second function performs authentication and other processing on the received data service request to decide to accept, reject or modify the data service request.

For the accepted data service request, the second function processes the one or more service requests, including merging the same data service request, and mapping the data service request to one or more data providing functions (application function, wireless access network function, base station (gNB) or centralized unit control plane (Centralized Unit-Control Plane, CU-CP) or centralized unit user plane (Centralized Unit-User Plane, CU-UP) or distributed unit (Distributed Unit, DU), UE function) data collection information.

Based on the mapping information, the second function is responsible for sending data collection control information, and/or data transmission channel control information, etc. to the corresponding data providing function.

Optionally, the received raw data or preprocessed data is sent to the first function according to the configuration information of the first function.

Optionally, when the UE acts as a data providing function or a data service consumer, a potential solution between the UE and the second function can be transparently transmitted through RRC, specifically including extending and defining an RRC message, which is forwarded to the first function by RRC It is implemented by performing processing, or a transport layer protocol is defined above the RRC layer, and RRC is one of the protocol layers.

Another potential solution for the UE and the second function introduces data resource control (DRC) when the UE acts as a data providing function or a data service consumer. The DRC message is terminated at the second function, so the above data service interaction can be processed by the radio access network L2/L1 and directly reach the second function, without forwarding by the existing RRC function.

Further, if the control information and data information of the service are separated, then a data transmission scheme for a data service between the UE and the second function is to use a dedicated data radio bearer (Data Radio Bearer, DRB), and the channel is based on each UE ( per UE) attribute, the data processed by the DRB is sent to the second function instead of the UPF. Another solution is to transmit data based on the transmission channel between the radio access network function node and the second function. The channel is a per node attribute, and the data of different UEs are distinguished by UE identifiers and/or subscription data identifiers.

For example, when the perception is used in the Internet of Vehicles or UAV scenarios, the perception faces the area where the vehicle or UAV travels, and it is necessary to provide perceived obstacle information with a very short delay. At this time, the sensing function can make a data service request with the first function in advance, and the first function maps the request to the second function according to the data service requirements of the sensing function, and sends corresponding authorization information and configuration to the second function and the sensing function. The second function sends data collection control information and data transmission channel control information to the radio access network function and/or UE function according to the received authorization information and configuration. Then the second function receives the data sent by the data providing function, and provides high real-time data service to the sensing function based on the above authorization and configuration information.

Based on the mapping information, if the second function and/or the third function provides the data service, the first function authorizes the second function and/or the third function and the corresponding data service requester respectively. One potential implementation is to distribute authorization tokens (tokens) and indicate the time interval for which the tokens are valid.

The relevant steps of the second function are briefly described as follows:

For the accepted data service request, the second function processes the one or more service requests, including merging the same data service request, and mapping the data service request to data collection information of one or more data providing functions (UEs) .

Based on the decision information of the data service request, preprocess the received data and provide it to the sender of the data service request

The third function may be a terminal-side data plane (UE-DP). The relevant steps of the third function are briefly described as follows:

According to the configuration information of the first function and/or the configuration information of the second function, the third function performs authentication and other processing on the received data service request to decide to accept, reject or modify the data service request.

For the accepted data service request, the third function processes the one or more service requests, including merging the same data service request, and mapping the data service request to one or more data providing functions (UE side protocol function, UE side application function) data acquisition information.

Based on the mapping information, the third function is responsible for sending data acquisition control information, and/or data transmission channel control information, etc. to the corresponding data providing function.

Optionally, the received raw data or preprocessed data is sent to the second function according to the configuration information of the second function.

For example, when the UE is an Internet of Vehicles or an unmanned aerial vehicle, the sensor on the UE is required to assist the communication sensing function to perform weather prediction or environment reconstruction in a certain area. When the first function receives the sensing function requesting the above-mentioned weather forecast or environment reconstruction sensor auxiliary information and communication sensing measurement data (such as received signal strength, etc.), the first function maps the data service requirements to the second function and the third function. function, and send configuration information to the second function and the third function. The second function performs radio resource scheduling according to the configuration information, and reports the requested measurement data of communication perception (such as received signal strength, etc.).
