In order to solve the problems of the data processing method in the prior art, the embodiment of the application provides a data processing method, a network device and a storage medium, wherein the network device receives a service request sent by a terminal; processing the service request based on a simplified network corresponding to a preset service scene; the simplified network is obtained after network function simplification processing is performed according to a preset service scene. The network can be optimized, and the performance of network equipment and terminals is improved.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

The embodiment of the application provides a data processing method, which is applied to network equipment, wherein the network equipment can integrate part or all of functions of an AMF; fig. 1 is a schematic implementation flow diagram of a data processing method according to an embodiment of the present application, as shown in fig. 1, the data processing method may include the following steps:

and step 101, receiving a service request sent by a terminal.

In the embodiment of the application, the network device may receive a service request sent by the terminal.

In the embodiment of the present application, the terminal is a terminal supporting a preset service scenario. That is, the network device only receives the service request transmitted by the terminal capable of supporting the preset service scenario.

Further, in the embodiment of the present application, the service request is information and/or a data packet sent by the terminal and used for executing a preset service scenario; for example, the service request may be a registration request, a connection establishment request, an authentication and authorization message, a security function message, or any data packet in a preset service scenario.

It should be noted that, in the embodiments of the present application, the network device may be used to deploy the RAN, for example, the network device may be a base station; meanwhile, the AMF can be integrated in the network equipment at the same time, so that the AMF is enabled to sink to the RAN side, a lightweight core network can be realized, a signaling flow on an N2 interface can be saved, interface interaction time delay is reduced, and interaction signaling is reduced.

102, processing a service request based on a simplified network corresponding to a preset service scene; the simplified network is obtained after network function simplification processing is performed according to a preset service scene.

In the embodiment of the application, after receiving the service request sent by the terminal, the network device processes the service request based on the simplified network corresponding to the preset service scene; the simplified network is obtained after network function simplification processing is performed according to a preset service scene.

It should be noted that in embodiments of the present application, the reduced network includes a reduced RAN and/or reduced AMF.

Further, in the embodiment of the present application, the preset service scenario refers to a 5G application scenario, and the preset service scenario may include a first service scenario, a second service scenario, a third service scenario, and a fourth service scenario; the first service scene comprises a service scene with high throughput, high reliability, ultra-low time delay and fixed position; the second service scene comprises a packet service scene with mobility, high reliability and ultra-low time delay; the third business scene comprises a business scene which performs sensor data acquisition and has a fixed position; the fourth traffic scenario includes a traffic scenario that performs sensor data acquisition and has mobility.

It should be noted that, in the embodiment of the present application, the 5G application scenario mainly includes three application scenarios, where one application scenario is an enhanced mobile broadband (Enhanced Mobile Broadband), which mainly refers to a large-flow mobile broadband service such as a three-dimensional ultra-high definition video; the other is mass internet of things communication (Massive Machine Type Communication, mctc), which refers to large-scale internet of things business, and is mainly oriented to application scenes of smart cities, environment monitoring, smart agriculture, forest fire prevention and the like for the purpose of sensor data acquisition; yet another is low latency Reliable communication (URLLC), such as industrial control systems, transportation and shipping (unmanned), smart grid and smart home management, interactive telemedicine diagnostics, and the like.

For the 5G application scenario, the first service scenario in the present application may be an enhanced mobile broadband, and is mainly characterized by high throughput, high reliability, ultra-low latency, and fixed location; for example, the first business scenario is a Virtual Reality technology (VR) game scenario in a campus; in addition, the second service scene is URLLC, and is mainly characterized by small packet service, high reliability, ultra-low time delay and mobility, such as an automatic driving scene; the third service scene can be mMTC with fixed position, and is mainly characterized in that the data acquisition of the sensor is relied on, and the position of the sensor is fixed; the fourth service scenario may be mctc with mobility, which is mainly characterized by relying on sensor data acquisition and the sensor has mobility; for example, a fourth business scenario may be data collection in mines, plants, power grids, which require periodic collection of data by onboard sensors of carts or drones, etc.

Further, the application adaptively simplifies the RAN and/or the AMF deployed in the network equipment aiming at the preset service scene, realizes the customized service aiming at the preset service scene, and optimizes the network; and when the network equipment and the terminal execute the target service corresponding to the preset service scene, the cost of the network equipment and the terminal connected with the network equipment and the terminal can be effectively reduced, and the performance of the network equipment and the terminal is improved.

It may be understood that, in the embodiment of the present application, after the network device performs network function simplification processing on the RAN, a simplified RAN may be obtained, and after the network function simplification processing is performed on the AMF, a simplified AMF may be obtained; the reduced network may consist of a reduced RAN and/or reduced AMF.

Further, in an embodiment of the present application, the network function simplification process may include the network device performing reduction of a protocol stack function for the RAN and performing reduction of a function for the AMF; among other things, the reduction of protocol stack functionality for the RAN includes a reduction of RRC, SDAP, RLC, and MAC layer functionality.

It should be noted that, in the embodiment of the present application, the service request corresponds to a preset service scenario, and the simplified network corresponds to the preset service scenario, that is, the simplified network may be used to process the corresponding service request, so as to complete the target service corresponding to the preset service scenario.

In an exemplary embodiment of the present application, if the preset service scenario is a first service scenario, the obtained simplified network corresponds to the first service scenario, and the simplified network may be used to process a service request corresponding to the first service scenario; for example, if the preset service scenario is a VR game scenario (first service scenario) in a park, the corresponding simplified network may be used to process a VR game service request corresponding to the VR game scenario.

In an exemplary embodiment of the present application, the service request sent by the terminal is a connection establishment request, where the terminal is a terminal supporting a preset service scenario; fig. 2 is a schematic implementation flow chart of a data processing method according to the embodiment of the present application, as shown in fig. 2, after receiving a connection establishment request sent by a target terminal (step 101 a), the network device processes the connection establishment request of the terminal based on the simplified network, so as to establish a connection with the terminal (step 102 b), that is, after processing the connection establishment request of the terminal, the network device may implement interworking with the terminal, so as to complete a subsequent target service corresponding to a preset service scenario.

Fig. 3 is an implementation schematic diagram of the data processing method according to the embodiment of the present application, as shown in fig. 3, a network device is located in a park, and is configured to implement a target service corresponding to a VR game scene (preset service scene), where the network device may establish a connection with a terminal, so as to complete a VR game service with the terminal.

Further, in the embodiment of the present application, the network device may also support cell selection and handover, and increase a priority ranking index during cell selection and handover; so that the best matching cell can be preferred to establish a connection with the target terminal.

Further, in the embodiment of the present application, the network device may broadcast, to the terminal, the relevant identification information of the corresponding preset service scenario, but does not display the name of the simplified network corresponding to the network device; for example, the relevant identification information may be network type information, where the network type information corresponds to a preset service scenario supported by the network device; therefore, the terminal can identify different network devices so as to correctly access the corresponding network devices, and the terminal is prevented from accessing other conventional networks, such as networks which are not distinguished according to preset service scenes and contain all network functions.

In addition, in the embodiment of the present application, the terminal may also report the network capability information, so that the network device may be able to know the network capability supported by the terminal, so that the network device prohibits the terminal that does not conform to the network function corresponding to the preset service scenario from accessing.

Further, if the preset service scenario is the first service scenario, before the network device processes the service request based on the simplified network corresponding to the preset service scenario, that is, before step 102, the method may further include the following steps:

Step 201, network function simplification processing is carried out on the RAN; wherein the network function simplification process includes at least one of: removing or disabling idle state, deactivated state, mobility function and measurement function in the radio resource control protocol layer RRC; removing or prohibiting service data adaptation protocol layer SDAP; removing or prohibiting a feedback mechanism ARQ function in an acknowledged mode AM in a radio link control protocol layer RLC; and removing or prohibiting different logic channel multiplexing or demultiplexing functions, logic channel priority management functions and resource overlapping priority management functions in the medium access control protocol layer MAC.

In the embodiment of the application, before the network device processes the service request based on the simplified network corresponding to the preset service scene, if the preset service scene is the first service scene, the network device can perform network function simplification processing on the RAN; wherein the network function simplification process includes at least one of: removing or disabling idle state, deactivated state, mobility function and measurement function in the radio resource control protocol layer RRC; removing or prohibiting service data adaptation protocol layer SDAP; removing or prohibiting a feedback mechanism ARQ function in an acknowledged mode AM in a radio link control protocol layer RLC; and removing or prohibiting different logic channel multiplexing or demultiplexing functions, logic channel priority management functions and resource overlapping priority management functions in the medium access control protocol layer MAC.

It may be understood that in the embodiment of the present application, if the preset service scenario is the first service scenario, the network device may perform adaptive network function simplification processing on the RAN according to the characteristics of the first service scenario.

For example, if the preset service scenario is the first service scenario, the network device may perform reduction of the protocol stack function for the RRC layer, the SDAP layer, the RLC layer, and the MAC layer on the RAN side.

For the RRC layer, an idle state (idle state) and a deactivated state (inactive state) in the RRC layer may be removed or disabled, only a connected state (connected state) is reserved, and since a role unlocking point is basically fixed in the scenario, no handover exists, a mobility function and a measurement function may be removed or disabled; in addition, in addition to the above-mentioned reduction of the protocol stack function, considering that the terminal where the user is located is not always in a communication state, the terminal can be guaranteed to have a sleep time by discontinuous reception (Discontinuous Reception, DRX) and discontinuous transmission (Discontinuous Transmission, DTX), but still remains in a connected state.

For the SDAP layer, because the QoS of the communication service data is fixed under the first service scene and can be directly corresponding to the corresponding DRB, the mapping from QoS flow to DRB by the SDAP layer is not needed any more, and the whole SDAP layer can be removed or forbidden.

For the RLC layer, ARQ function (in AM mode) which seriously affects time delay can be removed or forbidden, and reliability can be ensured by the HARQ function of the MAC layer with stronger ARQ function; in addition, in addition to the above-described reduction of the protocol stack function, it is also considered that high reliability requirements are ensured by adding semi-persistent scheduling repeat transmission, PDCP repeat (repetition), and the like.

For the MAC layer, due to QoS fixing, different logical channel multiplexing or demultiplexing functions can be removed or disabled, i.e. only the same logical multiplexing or demultiplexing function is reserved, and also a logical channel priority management function (logical channel prioritization) and a resource overlapping priority management function (priority handling between overlapping resources of one UE) can be removed or disabled; in addition, in addition to the above-described reduction of the protocol stack function, it is also possible to consider adding a preconfigured resource (CG) so that a resource request procedure (SR to BSR) and a physical layer dynamic scheduling resource procedure (DG) are not required.

Step 202, obtaining a simplified RAN corresponding to a first service scenario; the first service scene comprises a fixed-position service scene.

In the embodiment of the present application, if the preset service scenario is a first service scenario, after performing network function simplification processing on the RAN, the network device may obtain a simplified RAN corresponding to the first service scenario; the first service scene comprises a fixed-position service scene.

Further, if the preset service scenario is the second service scenario, before the network device processes the service request based on the simplified network corresponding to the preset service scenario, that is, before step 102, the method may further include the following steps:

step 301, performing network function simplification processing on the RAN; wherein the network function simplification process includes at least one of: removing or disabling idle and deactivated states in the RRC; removing or disabling the SDAP; removing or disabling segmentation functions under AM, re-segmentation functions and ARQ functions, segmentation functions under unacknowledged mode UM in RLC; in the MAC, the multiplexing or demultiplexing function of different logic channels, the logic channel priority management function and the resource overlapping priority management function are removed or forbidden.

In the embodiment of the application, before the network device processes the service request based on the simplified network corresponding to the preset service scene, if the preset service scene is the second service scene, the network device may perform network function simplification processing on the RAN; wherein the network function simplification process includes at least one of: removing or disabling idle and deactivated states in the RRC; removing or disabling the SDAP; removing or disabling segmentation functions under AM, re-segmentation functions and ARQ functions, segmentation functions under unacknowledged mode UM in RLC; in the MAC, the multiplexing or demultiplexing function of different logic channels, the logic channel priority management function and the resource overlapping priority management function are removed or forbidden.

It may be understood that in the embodiment of the present application, if the preset service scenario is the second service scenario, the network device may perform adaptive network function simplification processing on the RAN according to characteristics of the second service scenario.

For example, if the preset service scenario is the second service scenario, the network device may perform reduction of the protocol stack function for the RRC layer, the SDAP layer, the RLC layer, and the MAC layer on the RAN side.

Wherein, for the RRC layer, the idle state and the deactivation state in the RRC layer can be removed or forbidden, and only the connection state is reserved; in addition, in addition to the above-described reduction of the protocol stack function, since the terminal connected to the network is basically in a mobile state in most cases in the second traffic scenario, DRX/DTX can be added for a small number of non-mobile states.

For the SDAP layer, because the QoS of the communication service data is fixed under the second service scene and can be directly corresponding to the corresponding DRB, the mapping from QoS flow to DRB by the SDAP layer is not needed any more, and the whole SDAP layer can be removed or forbidden.

For the RLC layer, since the packet data does not need to be segmented in the second service scenario, the segmentation function (in UM mode and AM mode) and the re-segmentation function (in AM mode) can be removed or disabled, and the ARQ function (in AM mode) that seriously affects the delay can be removed or disabled, so that the reliability can be ensured by the HARQ function of the MAC layer with stronger function than the ARQ; in addition, in addition to the above-described reduction of the protocol stack function, it is also considered that high reliability requirements are ensured by adding semi-persistent scheduling repeat transmission, PDCP repeat (repetition), and the like.

For the MAC layer, as QoS is fixed, different logic channel multiplexing or demultiplexing functions can be removed or forbidden, namely, only the same logic multiplexing or demultiplexing function is reserved, and a logic channel priority management function and a resource overlapping priority management function can be removed or forbidden; in addition, in addition to the above-described reduction of the protocol stack function, it is also possible to consider adding preconfigured resources, so that a resource request procedure and a physical layer dynamic scheduling resource procedure are not required.

Step 302, obtaining a simplified RAN corresponding to a second traffic scenario; the second service scene comprises a packet service scene with mobility.

In the embodiment of the present application, if the preset service scenario is a second service scenario, after performing network function simplification processing on the RAN, the network device may obtain a simplified RAN corresponding to the second service scenario; the second service scene comprises a packet service scene with mobility.

Further, if the preset service scenario is the third service scenario, before the network device processes the service request based on the simplified network corresponding to the preset service scenario, that is, before step 102, the network device may further include the following steps:

Step 401, network function simplification processing is carried out on the RAN; wherein the network function simplification process includes at least one of: removing or disabling connection state, idle state and mobility functions in RRC; removing or disabling the SDAP; removing or disabling ARQ functionality in RLC; in the MAC, the multiplexing or demultiplexing function of different logic channels, the logic channel priority management function and the resource overlapping priority management function are removed or forbidden.

In the embodiment of the application, before the network device processes the service request based on the simplified network corresponding to the preset service scene, if the preset service scene is the third service scene, the network device may perform network function simplification processing on the RAN; wherein the network function simplification process includes at least one of: removing or disabling connection state, idle state and mobility functions in RRC; removing or disabling the SDAP; removing or disabling ARQ functionality in RLC; in the MAC, the multiplexing or demultiplexing function of different logic channels, the logic channel priority management function and the resource overlapping priority management function are removed or forbidden.

It may be understood that in the embodiment of the present application, if the preset service scenario is a third service scenario, the network device may perform adaptive network function simplification processing on the RAN according to characteristics of the third service scenario.

For example, if the preset service scenario is the third service scenario, the network device may perform reduction of the protocol stack function for the RRC layer, the SDAP layer, the RLC layer, and the MAC layer on the RAN side.

Wherein, for the RRC layer, the idle state and the connected state may be removed or disabled, only the deactivated state is reserved, and the mobility function may be removed or disabled due to the fixed location.

For the SDAP layer, also, under the fixed communication service scene, the QoS of the communication service data is fixed and can be directly corresponding to the corresponding DRB, so that the SDAP layer is not required to perform QoS flow to DRB mapping, and the whole SDAP layer can be removed or forbidden.

For the RLC layer, ARQ function which seriously affects time delay can be removed or forbidden, and reliability can be ensured by the HARQ function of the MAC layer with stronger ARQ function; the ARQ function can be reserved, and the HARQ function of the MAC layer is removed or forbidden; in addition, the segmentation function (in AM mode and UM mode) and the re-segmentation function (in AM mode) may also be removed or disabled when directed towards the packet traffic type in the third traffic scenario.

Step 402, obtaining a simplified RAN corresponding to a third traffic scenario; the third business scene comprises a business scene which performs sensor data acquisition and has a fixed position.

In the embodiment of the present application, if the preset service scenario is a third service scenario, after performing network function simplification processing on the RAN, the network device may obtain a simplified RAN corresponding to the third service scenario; the third business scene comprises a business scene which performs sensor data acquisition and has a fixed position.

Further, if the preset service scenario is the fourth service scenario, before the network device processes the service request based on the simplified network corresponding to the preset service scenario, that is, before step 102, the network device may further include the following steps:

step 501, network function simplification processing is carried out on the RAN; wherein the network function simplification process includes at least one of: removing or disabling the connected state and idle state in the RRC; removing or disabling the SDAP; removing or disabling ARQ functionality in RLC; in the MAC, the multiplexing or demultiplexing function of different logic channels, the logic channel priority management function and the resource overlapping priority management function are removed or forbidden.

In the embodiment of the application, before the network device processes the service request based on the simplified network corresponding to the preset service scene, if the preset service scene is the fourth service scene, the network device may perform network function simplification processing on the RAN; wherein the network function simplification process includes at least one of: removing or disabling the connected state and idle state in the RRC; removing or disabling the SDAP; removing or disabling ARQ functionality in RLC; in the MAC, the multiplexing or demultiplexing function of different logic channels, the logic channel priority management function and the resource overlapping priority management function are removed or forbidden.

It may be understood that, in the embodiment of the present application, if the preset service scenario is the fourth service scenario, the network device may perform adaptive network function simplification processing on the RAN according to the characteristics of the fourth service scenario.

For example, if the preset service scenario is the fourth service scenario, the network device may perform reduction of the protocol stack function for the RRC layer, the SDAP layer, the RLC layer, and the MAC layer of the RAN side.

Wherein, for the RRC layer, the idle state and the connected state may be removed or disabled, and only the deactivated state is reserved.

For the RLC layer, ARQ function which seriously affects time delay can be removed or forbidden, and reliability can be ensured by the HARQ function of the MAC layer with stronger ARQ function; the ARQ function can be reserved, and the HARQ function of the MAC layer is removed or forbidden; in addition, when the packet service type in the fourth service scenario is oriented, the segmentation function (in AM mode and UM mode) and the re-segmentation function (in AM mode) may be removed or disabled.

For the MAC layer, as QoS is fixed, different logic channel multiplexing or demultiplexing functions can be removed or forbidden, and logic channel priority management functions and resource overlapping priority management functions can be removed or forbidden; in addition, in addition to the above-described reduction of the protocol stack function, it is also possible to consider adding preconfigured resources, so that a resource request procedure and a physical layer dynamic scheduling resource procedure are not required.

Step 502, obtaining a simplified RAN corresponding to a fourth traffic scenario; the fourth service scenario includes a service scenario in which sensor data acquisition is performed and mobility is provided.

In the embodiment of the present application, if the preset service scenario is a fourth service scenario, after performing network function simplification processing on the RAN, the network device may obtain a simplified RAN corresponding to the fourth service scenario; the fourth service scenario includes a service scenario in which sensor data acquisition is performed and mobility is provided.

Further, before the network device processes the service request based on the simplified network corresponding to the preset service scenario, that is, before step 102, the network device may further include the following steps:

step 601, performing network function simplification processing on the AMF; the network function simplification process at least comprises at least one of a selection function for removing or prohibiting AMF, a switching function, a registration and subscription flow, a function body selection function for authentication, an N2 interface signaling flow and a mobility management function.

In the embodiment of the application, before the network device processes the service request based on the simplified network corresponding to the preset service scene, the network device may perform network function simplification processing on the AMF; the network function simplification process at least comprises at least one of a selection function for removing or prohibiting AMF, a switching function, a registration and subscription flow, a function body selection function for authentication, an N2 interface signaling flow and a mobility management function.

It may be appreciated that in the embodiment of the present application, if the AMF is integrated in the network device, the network function simplification process may be performed on the AMF.

In an embodiment of the present application, the mobility management function in the AMF may be removed or disabled when the preset traffic scenario is the first traffic scenario or the third traffic scenario, because the first traffic scenario and the third traffic scenario are fixed-position scenarios.

It can be understood that in the embodiment of the present application, since the second service scenario and the fourth service scenario are the scenarios with mobility, when the preset service scenario is the second service scenario or the fourth service scenario, the mobility management function in the AMF does not need to be removed or disabled.

For example, in the embodiment of the present application, if the preset service scenario is the first service scenario or the third service scenario, performing the network function simplification process on the AMF may include: a selection function to remove or prohibit AMF, a handover function, a registration and subscription procedure of new AMF and unified data management (Unified Data Management, UDM), a function body (Authentication Server Function, AUSF) selection function for authentication, an N2 interface signaling procedure, and a mobility management function; a simplified AMF corresponding to the first traffic scenario or the third traffic scenario may thereby be obtained.

For example, in the embodiment of the present application, if the preset service scenario is the second service scenario or the fourth service scenario, performing the network function simplification process for the AMF may include: removing or prohibiting a selection function, a switching function, a new registration and subscription flow of AMF and unified data management, a function body selection function of authentication and an N2 interface signaling flow of AMF; a simplified AMF corresponding to the second traffic scenario or the fourth traffic scenario may thereby be obtained.

Step 602, obtaining a simplified AMF.

In the embodiment of the present application, the network device may obtain a simplified AMF after performing network function simplification processing on the AMF.

In another embodiment of the present application, if the network device is not in an application environment corresponding to a preset service scenario in the implementation process of the data processing method provided in the embodiment of the present application, for example, the base station or the server (network device) is not in a range of a park or a factory building corresponding to the preset service scenario, the network device may be further connected to a public network, so as to interwork with the public network; the public network may also be carried in a server or a base station.

Illustratively, each park comprises a network device, the network device is provided with a RAN and an AMF, and different network devices in different parks can commonly access a public network to realize intercommunication with the public network; the AMF deployed in the public network is a first-level AMF, the AMF deployed in the network equipment is a second-level AMF, and the AMF in the network equipment is fused at the RAN side in a different manner from a simple plugboard, but is fused functionally; the network equipment and the public network are connected through a new interface. Fig. 4 is a second schematic implementation diagram of the data processing method according to the embodiment of the present application, as shown in fig. 4, where a first-level AMF is deployed in the public network; the terminal UE1 is communicated with the network equipment 1, the RAN1 and the secondary AMF1 are deployed in the network equipment 1 at the same time, and the network equipment 1 is accessed to the public network; the terminal UE2 is communicated with the network equipment 2, the RAN2 and the secondary AMF2 are deployed in the network equipment 2 at the same time, and the network equipment 2 is accessed to the public network; the terminal UEn is communicated with the network equipment n, the RANn and the secondary AMFn are deployed in the network equipment n at the same time, and the network equipment n is accessed to the public network. The UE1, UE2 and UE n and the corresponding network device 1, network device 2 and network device n may communicate with each other through Uu interfaces.

In the above example, the RAN and the secondary AMF deployed in the network device 1, the network device 2, and the network device n are a simplified RAN and a simplified AMF obtained after the network function simplification process.

That is, before the network device 1, the network device 2, and the network device n establish connections with the respective corresponding UE1, UE2, and UE n, the network device 1, the network device 2, and the network device n perform network function simplification processing according to the respective corresponding preset service scenarios, to obtain simplified networks corresponding to the respective preset service scenarios; for example, the network device 1 corresponds to a simplified network 1, the simplified network 1 including a simplified RAN1 and a simplified AMF1; the network device 2 corresponds to a simplified network 2, the simplified network 2 comprising a simplified RAN2 and a simplified AMF2; the network device n corresponds to a reduced network n, which includes a reduced RANn and a reduced AMFn.

The network equipment can perform network function simplification processing on the RAN based on different preset service scenes to obtain a simplified RAN corresponding to the preset service scenes; for example, if the preset service scenario is the first service scenario, the network device may remove or prohibit the idle state, the deactivated state, the mobility function, and the measurement function in the radio resource control protocol layer RRC; removing or prohibiting service data adaptation protocol layer SDAP; removing or prohibiting a feedback mechanism ARQ function in an acknowledged mode AM in a radio link control protocol layer RLC; removing or prohibiting different logic channel multiplexing or demultiplexing functions, logic channel priority management functions and resource overlapping priority management functions in a medium access control protocol layer (MAC); thereby obtaining a simplified RAN corresponding to the first traffic scenario; the first service scene comprises a fixed-position service scene.

For example, if the preset service scenario is the second service scenario, the network device may remove or prohibit the idle state and the deactivated state in the RRC; removing or disabling the SDAP; removing or disabling segmentation functions under AM, re-segmentation functions and ARQ functions, segmentation functions under unacknowledged mode UM in RLC; removing or prohibiting multiplexing or demultiplexing functions of different logic channels, a logic channel priority management function and a resource overlapping priority management function in the MAC; thereby obtaining a simplified RAN corresponding to the second traffic scenario; the second service scene comprises a packet service scene with mobility.

For example, if the preset service scenario is the third service scenario, the network device may remove or prohibit the connection state, the idle state, and the mobility function in RRC; removing or disabling the SDAP; removing or disabling ARQ functionality in RLC; removing or prohibiting multiplexing or demultiplexing functions of different logic channels, a logic channel priority management function and a resource overlapping priority management function in the MAC; thereby obtaining a simplified RAN corresponding to the third traffic scenario; the third business scene comprises a business scene which performs sensor data acquisition and has a fixed position.

For example, if the preset service scenario is the fourth service scenario, the network device may remove or prohibit the connection state and the idle state in RRC; removing or disabling the SDAP; removing or disabling ARQ functionality in RLC; removing or prohibiting multiplexing or demultiplexing functions of different logic channels, a logic channel priority management function and a resource overlapping priority management function in the MAC; thereby obtaining a simplified RAN corresponding to a fourth traffic scenario; the fourth service scenario includes a service scenario in which sensor data acquisition is performed and mobility is provided.

In addition, the network device can also perform network function simplification processing on the AMF, so as to obtain a simplified AMF; for example, if the preset service scenario is the first service scenario or the third service scenario, the network device may remove or prohibit the selection function, the switching function, the registration and subscription procedure, the authentication function, the N2 interface signaling procedure, and the mobility management function of the AMF, to obtain a simplified AMF corresponding to the first service scenario or the third service scenario.

For example, if the preset service scenario is the second service scenario or the fourth service scenario, the network device may remove or prohibit the selection function, the switching function, the registration and subscription procedure, the function body selection function of authentication and authorization, and the N2 interface signaling procedure of the AMF, to obtain the simplified AMF corresponding to the second service scenario or the fourth service scenario.

Thus, the different network devices in the above example each obtain a corresponding simplified network based on the corresponding simplified RAN and the simplified AMF, so as to receive a service request sent by the terminal using the simplified network, thereby executing a target service corresponding to a preset service scenario.

Further, based on the above example, fig. 5 is a schematic diagram showing a third implementation flow of a data processing method according to an embodiment of the present application, as shown in fig. 5, based on the above network device accessing the public network, the data processing method may include the following steps:

step 801, the network device receives registration information sent by the terminal.

In the embodiment of the application, the terminal may first send registration information to the network device.

It should be noted that, in the embodiment of the present application, the registration information may be plaintext information, which is different from the existing ciphertext information; if there is only one transmission service between the network device and the terminal, for example, only video transmission service, the registration information may include a connection establishment request message (RRC Setup Request), a registration request message, and an authentication/security function message; if there are two or more transmission services between the network device and the terminal, for example, video and voice transmission, the registration information needs to carry service information, so that the network device can establish PDU sessions (sessions) for different services.

Further, in the embodiment of the present application, the terminal sends the registration information, which may be triggered simultaneously for RRC connection, registration request, service information, authentication/security function, instead of serial triggering.

Step 802, the network device performs corresponding processing in response to the registration information.

In the embodiment of the application, after receiving the registration information sent by the terminal, the network device may perform corresponding processing in response to the registration information.

Step 803, the network device receives the completion confirmation message sent by the terminal.

In the embodiment of the present application, the network device may receive the completion acknowledgement message sent by the terminal after processing according to the registration information.

It should be noted that, in the embodiment of the present application, based on the simultaneous triggering of the RRC connection, registration request, service request, authentication/security function in the previous step, the completion confirmation message is also a corresponding message, rather than a plurality of messages corresponding to the serial triggering.

Step 804, the network device sends access request information to the public network.

In the embodiment of the present application, the network device may send the access request information to the public network after receiving the completion acknowledgement message sent by the terminal.

It may be appreciated that in the embodiment of the present application, the network device implements interworking with the public network by sending access request information to the public network.
