Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an RSU processing method, a terminal, and a storage medium based on mobile edge computing.
Background
V2X (vehicle to everything, i.e., vehicle-to-outside information exchange) is a communication technology developed based on collaborative intelligent transportation (C-ITS) and internet of vehicles (IoV), including vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P), vehicle-to-network (V2N), and the like. The V2X devices provide rich V2X applications through communication interaction. Aiming at the low-delay and high-reliability requirements of V2X application, the 3GPP is based on 4G LTE and 5G NR technologies, and C-V2X technology is introduced. C-V2X includes two phases, LTE-V2X and NR-V2X. LTE-V2X is based on LTE enhancements, supporting low-level assisted driving applications. NR-V2X is based on 5G enhancements, supporting high-level autopilot applications.
An RSU (Road Side Unit) is a V2X network device deployed on a Road Side, providing a large number of traffic infrastructure applications. 3GPP builds NR-V2X technology based on LTE and NR systems. For RSU devices, the 3GPP further gives two implementation options: one is a UE-type RSU (including UE and V2X Application function logic module) built based on 4G and 5G terminals, and the other is an NB-type RSU (including base station (eNB/gNB), co-located packet gateway (L-GW/UPF) and V2X Application Server module) built based on 4G and 5G base stations.
An RSU is a traffic device deployed on a roadside. Thus, in order to provide a continuous V2X application for roads, it is necessary to construct a traffic network along the road that is completely covered by RSU devices; for the UE-type RSU scheme, there is an advantage of easy implementation. However, one UE-type RSU device generally covers 200 to 300 meters, so that RSU devices need to be deployed along a road at high density, which causes low device resource utilization, resulting in problems of high construction cost, high operation cost, and the like; for the NB-type RSU scheme, the functions of the RSU and the base station are fused, the common site is deployed, the existing cellular network infrastructure is reused, and the total cost can be greatly reduced. However, because the base station equipment directly transmits the application layer information, the base station architecture needs to be modified to support the RSU application function, so that the problem of high construction difficulty occurs.
Accordingly, there is a need in the art for improvement.

An RSU is a traffic device deployed on a roadside. In order to provide a continuous V2X application for roads, a traffic network is required to be built along the road that is fully covered by RSU devices; for the UE-type RSU scheme, there is an advantage of easy implementation. However, one UE-type RSU device generally covers 200 to 300 meters, so that RSU devices need to be deployed along a road at high density, which causes low device resource utilization, resulting in problems of high construction cost, high operation cost, and the like; for the NB-type RSU scheme, the functions of the RSU and the base station are fused, the common site is deployed, the existing cellular network infrastructure is reused, and the total cost can be greatly reduced. However, because the base station equipment directly transmits the application layer information, the base station architecture needs to be modified to support the RSU application function, so that the problem of high construction difficulty occurs.
Aiming at the technical problems, the embodiment of the invention provides an RSU processing method based on mobile edge calculation, which separates an RSU from a base station, realizes an RSU scheme based on a mobile edge technology, reduces the construction difficulty of the RSU scheme, and can well solve the problems of RSU dynamic addition, resource dynamic adjustment, RSU dynamic switching and the like by introducing an RSU management module and an OBU management module into mobile edge calculation equipment, thereby reducing the cost of the RSU scheme.
As shown in fig. 1, an embodiment of the present invention provides an RSU processing method based on mobile edge calculation, including the following steps:
step S100, the mobile edge calculates and creates a corresponding RSU operation module according to the newly accessed base station, and allocates and adjusts communication calculation resources for the RSU operation module.
In this embodiment, the RSU processing method based on mobile edge calculation is applied to a terminal, where the terminal includes but is not limited to: mobile edge computing devices (i.e., mobile Edge Computing, MEC), computers, mobile terminals, and the like.
Aiming at the problem of the NB-type RSU scheme, the embodiment separates the base stations (eNB/gNB), introduces mobile edge calculation (Mobile Edge Computing, MEC; or called Multi-access edge calculation, multi-access Edge Computing, MEC) and deploys a V2X Application Server module to an MEC platform; as shown in fig. 2, the MEC is a service platform constructed based on a packet gateway (L-GW/UPF), deployed on the edge side of a cellular network, and supports low latency communication capability.
In this embodiment, considering that the MEC is a computing platform similar to cloud computing, access of multiple base stations may be supported; therefore, in this embodiment, the RSU function is implemented on the MEC platform by means of a software module.
Specifically, in one implementation manner of the present embodiment, the following steps are included before step S100:
and S010, the mobile edge calculates a pre-created RSU management module and an OBU management module.
In this embodiment, two modules are introduced on the MEC platform by means of software modules: an RSU Manager module (i.e., RSU management module) and an OBU Manager module (i.e., OBU management module); the RSU management module is used for managing RSU equipment accessed in the coverage area of the MEC platform, and the OBU management module is used for managing OBU equipment accessed in the coverage area of the MEC platform; both the RSU management module and the OBU management module can be obtained through corresponding configuration files.
Specifically, in one implementation manner of the present embodiment, step S100 includes the following steps:
step S101, the RSU management module creates a corresponding RSU operation module according to the newly accessed base station, and distributes communication computing resources to the RSU operation module according to RSU coverage and communication bandwidth;
step S102, initializing module parameters of the RSU operation module, and operating the RSU operation module according to the initialized module parameters;
step S103, according to the resource requirement of the RSU operation module, the communication computing resource of the RSU operation module is expanded.
In this embodiment, an MEC-type RSU (i.e., RSU running module) is created by the RSU Manager module and resource adjustment is performed.
As shown in fig. 3, when a system newly adds a wireless base station (i.e., a gNB) supporting RSU access, a control console of the MEC creates a MEC-type RSU for the base station through an RSU Manager module, and the MEC-type RSU can be implemented in various manners such as a virtual machine, a software module, and the like. When there are multiple MEC-type RSUs, the RSU Manager module supports communication and data sharing between the MEC-type RSUs.
As shown in fig. 4, in the process of creating the MEC-type RSU, the console sends a create request to the RSU Manager module, and after the RSU Manager module receives the request, the RSU Manager module allocates communication computing resources from the MEC platform based on parameters such as coverage, communication bandwidth, etc., and creates the MEC-type RSU X module; wherein the communication computing resources include: computing resources (e.g., CPU), storage resources (e.g., memory, storage), and network resources (e.g., network interface address, communication bandwidth).
Specifically, in one implementation manner of the present embodiment, step S103 includes the following steps:
step S103a, analyzing the resource demand quantity according to the extended resource request sent by the RSU operation module, and extending the computing resource, the storage resource and the network resource of the RSU operation module according to the resource demand quantity.
As shown in fig. 4, after creating the MEC-type RSU X module, initializing the module parameters and then starting the MEC-type RSU X module; in the running process of the MEC-type RSU X module, if the condition of resource overload is detected, an extended resource request is sent to the RSU Manager module, the RSU Manager module analyzes the resource demand quantity according to the extended resource request, resources are distributed from an MEC platform, and the resources of the MEC-type RSU X module are extended.
In the embodiment, by separating the RSU from the base station, the existing mobile network infrastructure can be reused, no modification requirement is required for the base station, and the existing network resources can be completely inherited; moreover, based on the mobile edge technology, the low-delay communication effect can be well ensured, and the development, deployment and maintenance cost of the RSU can be reduced in a software mode.
As shown in fig. 1, in an implementation manner of the embodiment of the present invention, the RSU processing method based on mobile edge calculation further includes the following steps:
and step 200, the RSU operation module provides service according to the vehicle state reported by each vehicle OBU in the coverage area of the corresponding base station, and establishes a service relationship between the vehicle and the RSU operation module.

Specifically, in one implementation manner of the present embodiment, in step S200, establishing a service relationship between the vehicle and the RSU includes the following steps:
step S201, the RSU operation module provides the OBU management module with vehicle information of the vehicle;
in step S202, the OBU management module registers as the RSU operation module of the vehicle service, and returns the history RSU operation module of the vehicle registration to the RSU operation module.
In this embodiment, the vehicle status reported by each vehicle OBU includes: information such as vehicle position, speed, azimuth and steering; as shown in fig. 5, when the vehicle travels in the cell of the gNB1 base station, the vehicle OBU1 reports the status to the MEC-type RSU1 corresponding to the gNB1 base station. After receiving the reported state, the MEC-type RSU1 registers a service point with the OBU Manager module, wherein the registered information comprises: the identification of the vehicle, the MEC-type RSU identification of the current service. In the process of the OBU Manager module registration, the OBU Manager module registers the MEC-type RSU1 providing the service and returns the history service point information.
When the vehicle runs into the cell of the gNB2 base station, the vehicle OBU1 reports to the MEC-type RSU2 corresponding to the gNB2 base station. After receiving the reported state, the MEC-type RSU2 registers a service point with the OBU Manager; in the process of registering the OBU Manager module, the OBU Manager module registers the MEC-type RSU2 for providing the service and returns the history service point information, thereby realizing the switching process from the MEC-type RSU1 to the MEC-type RSU 2.
In this embodiment, by introducing the RSU Manager module and the OBU Manager module into the MEC device, the problems of dynamic RSU addition, dynamic resource adjustment, dynamic RSU switching and the like can be well solved, and the development, deployment and maintenance costs of the RSU are reduced in a software manner.
As shown in fig. 5, in this embodiment, since the MEC-type RSU2 may need the history state data of the OBU1, the MEC-type RSU2 obtains the history state of the OBU1 according to the history service point returned by the OBU Manager. Wherein, the historical state data of OBU1 includes: the position, speed, direction angle, steering, etc. of the vehicle.
Specifically, in one implementation of the present embodiment, step S202 includes the steps of:
step S202a, the RSU operation module receives a history RSU operation module of the vehicle registration;
step S202b, the RSU running module detects whether the vehicle has just run within the coverage area of the RSU running module;
step S202c, if yes, acquiring a history state of the vehicle from the history RSU operation module;
in step S202d, the RSU operation module updates the state data of the vehicle according to the received historical state of the vehicle.
In this embodiment, in the process of acquiring the history state of the OBU1, the MEC-type RSU2 sends a request for the history state of the OBU1 to the MEC-type RSU1, and the MEC-type RSU1 sends the history state data of the OBU1 to the MEC-type RSU2 according to the request, so as to update the OBU state data in the MEC-type RSU 2.
In an implementation manner of the embodiment of the present invention, in step S200, the RSU operation module provides a service according to a vehicle state reported by each vehicle OBU within a coverage area of a corresponding base station, where the service includes the following steps:
step S210, acquiring a traffic signal state sent by a traffic signal controller;
step S220, determining the vehicle affected by the current traffic signal according to the traffic signal state and the vehicle state in the corresponding RSU operation module;
step S230, transmitting the traffic signal status to the determined OBU of the vehicle.
In this embodiment, various RSU application processing flows already defined by the current standard may be smoothly migrated to be executed on the MEC-type RSU. In this embodiment, an RSU issues a traffic signal as an example, and other application flows are available according to examples.
As shown in fig. 6, the traffic signal controller reports the traffic signal status to the MEC-type RSU1 when the signaling changes. The MEC-type RSU1 judges the affected vehicle according to the locally stored signal lamp and OBU positions; the judging method comprises the following steps: and identifying the correlation and urgency of the signal lamp and the vehicle according to the direction of the signal lamp, the lane where the vehicle is located and the distance between the vehicle and the signal lamp, and determining the affected vehicle according to the correlation and urgency of the vehicle.
After determining the affected vehicles, the MEC platform issues traffic signal status to the corresponding OBU. After the traffic signal state is acquired, the vehicle is planned to run so as to avoid being influenced by the signal of the current traffic signal controller.
