Configuration information coordination and storage method and device
Technical Field

Background
Currently, in Vehicle-to-Vehicle (V2X) communication, various communication modes such as Vehicle-to-Vehicle (V2V), Vehicle-to-Infrastructure (V2I), Vehicle-to-Pedestrian (V2P) and the like can be supported. Wherein V2V is vehicle-to-vehicle communication; V2I is the communication between the vehicle and infrastructure on the roadside, such as traffic lights at intersections or road signs; V2P is the communication between the terminals of the vehicle and the pedestrian.
Referring to fig. 1, a diagram of a network architecture of V2X in a non-roaming scenario specified by 3rd Generation Partnership Project (3 GPP) protocol is shown. User Equipment (UE) communicates with a V2X Control unit (Control Function) through a V3 interface, and UEs can directly communicate with each other through a direct communication (PC5) interface, such as a PC5 interface between UEs a to UE D in fig. 1. In V2X communication, when a Mode (Mode)4 direct communication Mode is adopted, configuration information required by the UE may be configured in three ways, that is, network configuration, pre-configuration, and cloud (OTT) Mode configuration.
However, due to the existence of multiple configuration manners, it is likely that the UEs in the network that need to perform V2X communication obtain configuration parameters through different configuration manners, which may cause configuration information between UEs to be different, and the current 3GPP protocol or existing V2X communication technology does not provide a function of parameter coordination, so if the configuration information between UEs is different, communication may be impossible between UEs, or communication quality may be poor even though communication is still possible between UEs.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.
The technical background of the embodiments of the present invention is described below.
Currently, in V2X communication, when a Mode (Mode)4 direct communication Mode is adopted, configuration information required by a communication node may be configured in three ways, namely, network configuration, pre-configuration, and cloud (OTT) Mode configuration. However, due to the existence of multiple configuration modes, it is likely that configuration parameters are obtained between nodes in the network that need V2X communication through different configuration modes, that is, configuration information between nodes may be different, and the current 3GPP protocol or the existing V2X communication technology does not provide a function of parameter coordination, so if configuration information between nodes is different, communication between nodes may be impossible, or even if communication between nodes is possible, communication quality may be poor.
In view of this, an embodiment of the present invention provides a method for storing configuration information among communication nodes in an internet of vehicles, where in the method, a cloud device coordinates configuration information of a multi-party network, and a source of the configuration information is unified to the cloud device, so that the source of the configuration information is only the cloud device, and the configuration information is further unified from the source. In addition, in the method, the problem that different versions of configuration information may still exist between different communication nodes is also considered, so when different communication nodes communicate, the versions of the node and an opposite party are compared, and if the version of the opposite party is newer, the configuration information of the node and the version of the opposite party is updated according to the configuration information of the opposite party, so that the configuration information of the node and the configuration information of the opposite party are consistent, and the problems that communication cannot be performed or communication quality is poor are solved. In addition, when the node cannot be connected with a cellular network or cloud equipment, the configuration information of the node can be updated in such a way, so that the validity of the configuration information of the node is ensured, and the communication quality is further improved.
Fig. 2 is a diagram of an application scenario according to an embodiment of the present invention. The cloud device may be capable of communicating with multiple networks, such as an operator cellular network, an OEM (Original Equipment Manufacturer) owned network, and a third party operating network shown in fig. 2, which may also include other possible networks, which is not limited in this embodiment of the present invention. The above networks may also configure the UE with configuration information for direct communication between UEs through a PC5 interface, and the UEs shown in fig. 2 are all vehicles, but it should be understood that the UE is not limited to vehicles, and may also be road-side infrastructure equipment, pedestrians, and the like. The vehicle is a communication device installed in the vehicle, and the pedestrian is a communication device held by the pedestrian, and the communication device may be a mobile phone or a tablet computer (PAD), for example.
The technical scheme provided by the embodiment of the invention is described in the following with reference to the accompanying drawings.
Referring to fig. 3, an embodiment of the present invention provides a method for storing configuration information between communication nodes in an internet of vehicles, where the method may be executed by a cloud device in an application scenario shown in fig. 3. The flow of the method is described below.
S301: the cloud device receives configuration information sent by a plurality of networks.
In the embodiment of the invention, in order to enable the sources of the configuration information configured for the communication nodes of the internet of vehicles to be unified to the cloud device, the cloud device can acquire the configuration information used by a plurality of networks so as to coordinate the configuration information of the plurality of networks.
The configuration information includes radio (radio) parameters used for air interface interaction for communication between communication nodes in the internet of vehicles. The communication node may be a vehicle, road side infrastructure or a pedestrian.
S302: and the cloud equipment determines new configuration information according to the configuration information sent by the plurality of networks.
In the embodiment of the present invention, the configuration information used by each of the plurality of networks may be different, and in order to make the configuration information more uniform, the cloud device may determine new configuration information by referring to the received configuration information sent by the plurality of networks.
S303: the cloud device determines whether the new configuration information is acceptable to multiple networks.
Since the new configuration information may not be applicable to all networks, after the cloud device determines the new configuration information, the cloud device may also query the plurality of networks to determine whether the determined new configuration information can be accepted.
If any network in the plurality of networks does not accept the new configuration information, the cloud device adjusts the new configuration information until the final configuration information is accepted by all the plurality of networks.
S304: and when the determination result is yes, the cloud device stores the new configuration information.
If all networks can accept the new configuration information, the cloud device can store the new configuration information.
When the cloud device stores, in order to distinguish the configuration information of different versions, the configuration information may further include one or more of the following information:
(1) version information indicating the version of the stored configuration information, for example, the version information indicates V1.2.1.
(2) The generation time is the time of generating the configuration information, and is, for example, 38 minutes and 40 seconds at 10 o 'clock, 27 o' clock, 10 o 'clock, and 27 o' clock in 2017.
(3) The expiration time is a time when the configuration information cannot be used continuously, for example, the expiration time is 10 o 'clock 38 min 40 sec at 11/27/2017, and then the configuration information is expired and cannot be used continuously at 11/27/2017 and 10 o' clock 38 min 40 sec at 10.
(4) Version change information is information for setting a Modulation and Coding Scheme (MCS) range supporting Quadrature Amplitude Modulation (16 QAM) in addition to the previous version v1.2.0, where configuration information of the version changes compared with the previous version.
Specifically, since the configuration information applied to different types of communication nodes is different, the configuration information stored in the cloud device may further include a node type to which the configuration information is applied, where the node type is used to indicate the type of the communication node to which the configuration information is applied, for example, the node type is a vehicle, an infrastructure, or a pedestrian.
After the cloud device stores the configuration information, the configuration information may be configured to the communication nodes in the internet of vehicles in a variety of ways. The specific configuration modes are as follows.
The network configuration mode is as follows:
when the UE is in the coverage of the cellular Network, after the Network side obtains the configuration information from the cloud device, the Network side may configure the configuration information to the UE through a V3 interface, that is, configure information of a Public Land Mobile Network (PLMN) capable of performing V2X communication for the UE. The UE may attach through an authentication procedure on a PLMN authorized for V2X communication after accessing the cellular network. In this way, if the System Information Block (SIB) includes Information of the transmission resource pool, the UE may communicate directly through the PC5 interface without entering a connected state; if the SIB does not include the information of the transmission resource pool, the UE further needs to enter a connected state to obtain the information of the transmission resource pool through a dedicated configuration message. The 3GPP protocol specifies an authorized PLMN information association timeout timer configured in the cellular coverage for V2X communication, and after the timer expires, the UE will attempt to acquire new configuration information from the V3 interface.
The pre-configuration mode comprises the following steps:
when the UE is out of the coverage of the cellular network, the vehicle OEM may also obtain configuration information from the cloud device, and configure the configuration information to the UE in a preconfigured manner, so that the UE may directly obtain the required wireless parameter configuration information through the preconfigured configuration information. The pre-configuration can be that the vehicle OEM performs configuration at factory setting; alternatively, the configuration information for out-of-coverage pre-configuration may be obtained through the V3 interface when the UE is in the coverage of the cellular network.
The configuration information for V2X communication, which specifies an out-of-cellular configuration in 3GPP protocols, may also be associated with a timeout timer, and when the timer expires, the UE may attempt to reacquire new configuration information from the V3 interface.
Cloud configuration mode:
no matter the UE is within the coverage range of the cellular network or outside the coverage range, as long as the UE can be connected to the cloud device, for example, when the UE can be connected to the cloud device through a WIreless Fidelity (WIFI) network or a dedicated access network, the UE may also directly obtain the configuration information stored by the cloud device from the cloud device.
Similarly, the configuration information obtained by the cloud configuration mode may also be associated with a timeout timer. When the timer expires, the UE may attempt to retrieve new configuration information from the cloud device.
In the embodiment of the present invention, after the configuration information has been configured in the UE, when two UEs are within a communicable range, the two UEs can communicate through the configuration information configured for the two UEs. Of course, since the configuration modes of the two UEs may be different, versions of the configuration information may also be different, or there may be a problem that communication cannot be performed or communication quality is poor, please refer to fig. 3, an embodiment of the present invention further provides a method for storing configuration information between communication nodes in the car networking, which may be performed by the UEs in the car networking. The process of the method is described as follows: in the following description, two UEs, i.e. a first node and a second node, are taken as an example for description, and both the first node and the second node may be any type of communication node in a communication node of an internet of vehicles, such as a vehicle, an infrastructure, or a pedestrian.
S401: the first node determines the configuration information with a newer version in the first configuration information of the first node and the second configuration information of the second node.
In the embodiment of the present invention, in order to avoid the problem that the first node cannot communicate or the communication quality is poor due to different configuration information with a second node with which communication needs to be performed, when the first node communicates with the second node, the first node further determines configuration information with a newer version in the first configuration information of the first node and the second configuration information of the second node.
Specifically, when the first node and the second node are in a communicable range, the first node may receive a message sent by the second node, where the message may carry information for distinguishing between different versions of configuration information, and the first node may determine, according to the information, which version of the configuration information is newer in the first configuration information and the second configuration information.
The information for distinguishing the configuration information of different versions may be, for example, the version information, the generation time, the expiration time, or the version change information.
In the embodiment of the present invention, the message sent by the second node and received by the first node may further indicate a node type to which the second configuration information is applicable, so that before the first node determines that the version of the configuration information is newer in the first configuration information of the first node and the second configuration information of the second node, the first node may further determine whether the second configuration information is applicable to the first node, and if so, the first node may determine which version of the first configuration information and the second configuration information is updated; if not, the first node does not need to make a determination.
S402: and if the first node determines that the second configuration information is the configuration information with the newer version, the first node updates the configuration information of the first node according to the second configuration information.
If the first node determines that the version of the second configuration information is newer, the first node may request the second node to send the second configuration information to the first node, so that the first node can update its own configuration information according to the second configuration information. Specifically, the first node may directly use the second configuration information, or modify the first configuration information according to a difference between the second configuration information and the first configuration information.
In the embodiment of the invention, after the first node updates the configuration information of the first node, the configuration information between the first node and the second node is the same, so that the communication between the first node and the second node can be effectively carried out, and the communication experience quality of a user is improved.
In the embodiment of the present invention, if the first node determines that the version of the first configuration information of the first node is newer, the first node may actively send the first configuration information to the second node, or send the first configuration information to the second node after waiting for the second node to initiate a request, so that the second node can update the configuration information of the second node.
The scheme of the embodiment of the present invention will be described below with specific examples.
In the embodiment of the present invention, when the first node and the second node are communication nodes of the same type, configuration information with a newer version in the first configuration information and the second configuration information may be determined according to the following method without considering the node type to which the first configuration information and the second configuration information are applicable.
(1) Determining the configuration information with a newer version according to the version information:
if the message sent by the second node and received by the first node carries the version information of the second configuration information, the first node may compare the version information of the first configuration information with the version information of the second configuration information, and then determine the configuration information with a newer version in the first configuration information and the second configuration information.
Specifically, for example, if the version information of the first configuration information is v1.2.0, and the version information of the second configuration information is V1.2.1, the first node may determine that the version of the second configuration information of the second node is updated, and then the first node may initiate a request to the second node to request the second node to send the second configuration information to itself, and then the first node may update its own configuration information according to the second configuration information.
(2) Determining the configuration information with a newer version according to the generation time:
If the message sent by the second node and received by the first node carries the generation time of the second configuration information, the first node may compare the generation time of the first configuration information with the generation time of the second configuration information, and then determine the configuration information with a newer version in the first configuration information and the second configuration information.
Specifically, for example, the generation time of the first configuration information is 2017, 9, 27, 10, 38, and 40 seconds, the generation time of the second configuration information is 2017, 10, 27, 10, and 38, and 40 seconds, the first node may determine that the version of the second configuration information of the second node is updated, and then the first node may initiate a request to the second node to request the second node to send the second configuration information to itself, and then the first node may update its own configuration information according to the second configuration information.
(3) Determining the configuration information with a newer version according to the failure time:
if the message sent by the second node and received by the first node carries the expiration time of the second configuration information, the first node may compare the expiration time of the first configuration information with the expiration time of the second configuration information, and then determine the configuration information with a newer version in the first configuration information and the second configuration information.
Specifically, for example, the expiration time of the first configuration information is 11/27/10/38/40 seconds in 2017, and the generation time of the second configuration information is 27/38/40 seconds in 2017, the first node may determine that the version of the second configuration information of the second node is updated, and then the first node may initiate a request to the second node to request the second node to send the second configuration information to itself, and then the first node may update its configuration information according to the second configuration information.
In the embodiment of the present invention, when the first node and the second node are different types of communication nodes, first, the node type to which the first configuration information and the second configuration information are applicable needs to be considered.
Specifically, the first node, in the message received by the second node, may carry information used for characterizing the version of the second configuration information, and may also carry information of a node type to which the second configuration information is applicable. For example, the type of the node to which the first configuration information is applicable is a road side device, and the type of the node to which the second configuration information is applicable is a vehicle and a road side device, then the first node may determine that the second configuration information is applicable to the node, and in addition, the first node may also determine, according to information carried in the message and used for representing the version of the second configuration information, configuration information with a newer version in the first configuration information and the second configuration information. For the determination process, reference may be made to the descriptions in (1) to (3) above, and details are not described here.
If the first node determines that the second configuration information is applicable to the node, and simultaneously determines that the version of the second configuration information is updated compared with the version of the first configuration information of the node, the first node may initiate a request to the second node to request the second node to send the second configuration information to the first node, and the first node may update the configuration information of the first node according to the second configuration information.
