Description

Method and equipment for converting communication mode

Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to a method and a device for converting a communication mode.

Background

Currently, two main communication modes exist in the field of wireless communication:

a communication mode via a network and a direct communication mode.

1. Communication mode via network

The conventional way of communicating via a network is shown in fig. 1A, where a Uu interface is used between a base station and a terminal (UE):

for a communication mode through a network, if a sending terminal (UE) needs to send data, the data is firstly sent to a base station through a Uu interface between the terminal and a service base station of the sending terminal, then the base station sends the data from a receiving end to an external server through core network equipment, the external server judges whether the data needs to be sent to other terminals, if so, the data is forwarded to the service base station of the receiving terminal, and the service base station of the receiving terminal sends the data to the receiving terminal through the Uu interface.

2. Direct communication mode

The manner of direct communication is shown in fig. 1B:

the terminals adopt a D2D (Device to Device) technology to realize direct communication.

V2X (vehicle-to-Everything) communication is a popular issue in the field of communication. V2X communication mainly contains three aspects:

V2V (Vechile-to-Vechile, car-to-car): communication between OBUs (On Board Unit) On the vehicle.

V2I (vehicle-to-Infrastructure, lane network): communication between the vehicle and an RSU (Road Side Unit).

V2P (vehicle-to-Pedestrian): communication between the vehicle and the pedestrian.

For V2X, if the communication manner via the network shown in the above (1) is used, it can be referred to as V2X communication via the network (simply referred to as Uu V2X); if V and X use the direct communication mode described in the above (2), it can be called V2X direct communication (abbreviated as PC5V 2X).

The two communication modes of the PC5V2X and the Uu V2X are respectively good and bad. The advantages of PC5V2X are: the time delay is short, and the transmission efficiency is high; but its reliability may be deteriorated as the distance between the terminals increases or an obstacle blocks. In contrast, Uu V2X has a relatively long delay and low transmission efficiency, but its reliability is relatively guaranteed. For the vehicle network, the actual road condition is complicated and relatively variable. For urban environments, relatively serious shielding may exist, and the reliability of communication cannot be guaranteed by simply using the PC5V 2X; for the case of no occlusion of the highway, the use of Uu V2X alone has the disadvantages of low resource efficiency and long time delay. Therefore, the communication performance of the internet of vehicles needs to be optimized by reasonably converting the two communication modes.

At present, no scheme for switching communication modes exists in V2X communication, so that the performance of V2X communication is affected.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It is to be noted that a and/or B appearing in the following description includes three meanings, 1, a; 2. b; 3. a and B.

In practice, the V2X terminals of embodiments of the present invention include some or all of the following:

a V2X terminal (PC 5V2X transmission terminal for short) which is a transmission side and is in a PC5V2X communication system;

a V2X terminal (PC 5V2X receiving terminal for short) which is a receiving side and is in the PC5V2X communication system;

a V2X terminal (Uu V2X transmission terminal for short) on the transmission side in the Uu V2X communication scheme;

a V2X terminal (Uu V2X reception terminal) on the reception side is in the Uu V2X communication scheme.

Optionally, for the case of moving into or being located in the Uu V2X area all the time, the V2X terminal performing communication mode switching is a PC5V2X transmitting terminal;

for the case of moving out of the Uu V2X area or being located in the non-Uu V2X area all the time, the V2X terminal performing the communication scheme switching may be a transmission terminal of Uu V2X or a transmission terminal using Uu V2X and PC5V2X at the same time.

As shown in fig. 2A, the system for converting a communication scheme according to the embodiment of the present invention includes: a network side device 10 and a V2X terminal 20.

A network side device 10 for determining a target area using a target communication method in V2X communication; generating communication mode switching information according to the determined target area; sending the communication mode switching information to the V2X terminal; wherein, the target communication mode is a Uu V2X communication mode and/or a PC5V2X communication mode.

The V2X terminal 20 is configured to receive the communication scheme switching information sent by the network side device, and perform communication scheme switching according to the received communication scheme switching information.

The network side device according to the embodiment of the present invention may determine the target area using the target communication method in V2X communication according to part or all of the following methods:

the network side equipment determines a target area using a target communication mode in V2X communication according to auxiliary information reported by the V2X terminal and/or sent by other network side equipment;

the network side equipment determines a target area using a target communication mode in V2X communication according to configuration information of OAM (operation and Maintenance) equipment;

and thirdly, the network side equipment determines a target area using a target communication mode in V2X communication according to local configuration information (such as map information).

The following are described separately.

And in the first mode, the network side equipment determines a target area using a target communication mode in V2X communication according to auxiliary information reported by the V2X terminal and/or sent by other network side equipment.

If the first mode needs to be executed, the network side device may further notify the V2X terminal of the configuration information before determining the target area using the target communication mode in the V2X communication according to the auxiliary information reported by the V2X terminal;

correspondingly, after receiving the configuration information for reporting the auxiliary information, which is issued by the network side device, the V2X terminal reports the auxiliary information according to the configuration information for reporting the auxiliary information.

The configuration information for reporting the auxiliary information may be a reporting period of the auxiliary information and/or a triggering event of reporting the auxiliary information.

If the configuration information for reporting the auxiliary information includes an auxiliary information reporting period, the V2X terminal reports the auxiliary information to the network side device after the auxiliary information reporting period arrives.

And the reporting period of the auxiliary information is a time period and/or a distance period.

Specifically, the auxiliary information may be a period of a time dimension, such as recording the auxiliary information once every several times (e.g., 1 second); it may also be a period of spatial dimension, for example, when the V2X terminal moves a certain distance (for example, 1 meter) to trigger one-time recording of the auxiliary information.

The trigger event for reporting the auxiliary information comprises part or all of the following events:

For example, if the PC5V2X sends and/or receives a message N times (N > ═ 1), the reporting of the auxiliary information is triggered; or the distance from the terminal V2X to the last reporting position exceeds M meters (M > -1), triggering the auxiliary information reporting.

The V2X terminal needs to record the auxiliary information before reporting the auxiliary information.

Optionally, the V2X terminal records the auxiliary information after the recording period arrives; and/or

The recording period is a time period and/or a distance period;

the specific recording period may be a period of a time dimension, such as recording the auxiliary information once every several times (e.g. 1 second); it may also be a period of the spatial dimension, such as the UE moving a few distances (e.g. 1 meter) triggering one secondary information recording.

The recording event comprises part or all of the following events:

when the V2X terminal transmits twice or receives twice or transmits once, the auxiliary information is recorded when the terminal position interval exceeds X meters, and X is a positive number.

The V2X terminal is a transmitting terminal, and the auxiliary information includes, but is not limited to, some or all of the following information:

the V2X terminal is a receiving terminal, and the auxiliary information includes but is not limited to some or all of the following information:

The position information may be GPS (Global Positioning system) coordinates and/or a target area number.

In implementation, after a period of time for reporting the auxiliary information, if the base station can determine the target area more accurately, the base station may notify the V2X terminal to stop reporting the auxiliary information through broadcasting or dedicated signaling. When necessary, the terminal is notified to start the auxiliary information reporting again through broadcasting or dedicated signaling (for example, the base station verifies whether the target area determined before needs to be modified once every several times).

Since the auxiliary information does not need to be reported all the time, the network side device may notify the V2X terminal to start the function of reporting the auxiliary information through broadcasting or a dedicated signaling after the V2X terminal needs to report the auxiliary information;

after the V2X terminal is not required to report the auxiliary information, the V2X terminal is informed to close the function of reporting the auxiliary information through broadcasting or special signaling;

correspondingly, after receiving the opening notification, the V2X terminal opens the function of reporting auxiliary information, and reports auxiliary information according to the configured reporting condition;

and after receiving the closing notification, the V2X terminal closes the auxiliary information reporting function and notifies the reporting of auxiliary information.

Optionally, if the auxiliary information received by the network side device includes information related to other cells, the network side device may further send the auxiliary information to the related cells.

Specifically, for a cell managed by the network side device, after receiving auxiliary information reported by the V2X terminal and/or sent by other network side devices, the network side device sends all contents of the auxiliary information to the corresponding other cells if the auxiliary information includes other cells; or

In the following, the target communication method is Uu V2X communication method, and the V2X terminal that reports the auxiliary information may include PC5V2X transmitting terminal and PC5V2X receiving terminal.

If the PC5V2X receiving terminal is located at the edge of the cell, after the serving base station of the PC5V2X receiving terminal receives the auxiliary information reported by the PC5V2X receiving terminal, it is further necessary to interact the auxiliary information reported by the PC5V2X receiving terminal with the base station adjacent to the PC5V2X receiving terminal of the reported auxiliary information through the inter-base station interface.

The base station integrates the auxiliary information reported by the PC5V2X sending terminal and the PC5V2X receiving terminal to determine the target area needing to use UuV2X communication mode. The method for specifically determining the area needing to use Uu V2X belongs to the realization of a base station algorithm, and can be realized in various ways, which cannot be listed one by one. Only one possible example of an algorithm is given here:

the base station determines the time and the position of the PC5V2X sending terminal sending PC5V2X message according to the auxiliary information reported by the PC5V2X sending terminal, and determines the V2X receiving terminal in the coverage radius range of the PC5V2X by combining the map information and the coverage radius of the PC5V 2X.

Then, according to the auxiliary information reported by the V2X receiving terminal, it is determined that if there is a PC5V2X receiving terminal at the time when the PC5V2X sending terminal sends the PC5V2X message in a certain direction, but all or most of the PC5V2X terminals in the direction cannot receive the PC5V2X message sent by the PC5V2X sending terminal, the region is a target region that needs to use Uu V2X.

Further description is made by taking fig. 2B as an example. In fig. 2B, PC5V2X receiving terminal 1, PC5V2X receiving terminal 2 and PC5V2X receiving terminal 3 are all located in the coverage area of PC5V2X transmitting terminal 1 and PC5V2X transmitting terminal 2, but PC5V2X receiving terminal 3 can receive PC5V2X signals sent by PC5V2X transmitting terminal 1 and PC5V2X transmitting terminal 2, but PC5V2X receiving terminal 1 and PC5V2X receiving terminal 2 do not receive, so that the area where PC5V2X transmitting terminal 1 and PC5V2X transmitting terminal 2 are located can be determined as the target area where Uu V2X needs to be used.

And secondly, the network side equipment determines a target area using a target communication mode in V2X communication according to the configuration information of the OAM equipment.

In implementation, the OAM equipment is responsible for updating and maintaining the information of the target area that needs to use Uu V2X, and the base station is notified in time once there is an update;

accordingly, the base station determines a target area requiring use of Uu V2X according to the information notified by the OAM equipment.

The base station determines a target area requiring use of Uu V2X based on preconfigured information, such as map information.

The specific algorithm depends on the implementation of the base station, for example, the base station can determine that several meters of square circles of the crossroads or T-junctions are target areas needing to use Uu V2X; the area with more buildings can be used as a target area needing to use Uu V2X.

Optionally, the network side device may generate communication mode switching information according to the area information of the target area; or

The network side device may determine a communication method in the V2X communication of the V2X terminal according to the position of the V2X terminal and the determined target area, and generate communication method switching information according to the determined communication method.

In implementation, the network side device generates communication mode switching information according to the area information of the target area, and the area information can be used as the communication mode switching information or be a part of the communication mode switching information;

the network side device generates the communication method switching information according to the determined communication method, and the communication method can be used as the communication method switching information or can be used as a part of the communication method switching information.

When the network side device transmits the communication method switching information, the communication method switching information may be transmitted in any message that can be received by the V2X terminal.

The following describes the processing modes of different area information.

Firstly, the area information of the area is used as communication mode switching information.

In this manner, the area information is any information that can determine an area.

And the network side equipment sends the communication mode switching information to the V2X terminal through broadcasting or special signaling.

Dedicated signaling includes, but is not limited to, some or all of the following:

RRC (Radio Resource Control) signaling, MAC (Medium access Control) signaling, and physical layer signaling.

If the target communication mode is Uu V2X communication mode, after the V2X terminal receives the broadcast message:

the V2X terminal judges that the terminal is located in or enters a target area needing to use Uu V2X, and then the PC5V2X is switched to UuV 2X;

if the terminal judges that it is not located in or has moved out of the target area where Uu V2X needs to be used, Uu V2X is switched to PC5V 2X.

If the target communication mode is Uu V2X communication mode and PC5V2X communication mode, after the V2X terminal receives the broadcast message:

the V2X terminal judges that the terminal is located in or enters a target area needing to use Uu V2X, and then uses the PC5V2X and Uu V2X at the same time;

if the V2X terminal determines that it is not located in or has moved out of the target area where use of Uu V2X is desired, then PC5V2X is used only.

Second, the communication mode is used as communication mode switching information

In this way, the network side device sends the communication mode switching information to the V2X terminal through dedicated signaling.

RRC signaling, MAC signaling, physical layer signaling.

In implementation, the base station locates the V2X terminals, determines that V2X terminals within the target area of Uu V2X need to be used, and notifies these V2X terminals to perform handover through dedicated signaling.

If the target communication mode is Uu V2X communication mode, the V2X terminal notification process is as follows:

if the V2X terminal is located in the determined target area or enters the determined target area, the base station informs the V2X communication mode of the V2X terminal to be a Uu V2X communication mode;

and if the V2X terminal is not located in the determined target area or moves out of the determined target area, the base station informs the V2X communication mode of the V2X terminal to be a PC5V2X communication mode.

Optionally, the recording period is a time period and/or a distance period;

The following describes the embodiments of the present invention by way of examples.

Example 1: auxiliary information configuration and reporting process (broadcast mode)

As shown in fig. 9, a first method for reporting auxiliary information according to the embodiment of the present invention includes:

step 1: the base station determines the area in which the auxiliary information needs to be reported.

In implementation, the base station determines whether there is a priori information (such as map information, previously determined area information that requires Uu V2V);

if no prior information exists, the cell managed by the base station can be directly determined to be the area needing to report the auxiliary information;

if the base station has the prior information, an area (such as an intersection) possibly having occlusion can be preliminarily determined according to the prior information to be used as an area needing to report the auxiliary information.

Step 2: and the base station sends the configuration information required for reporting the auxiliary information to the V2X terminal in the area in a broadcasting mode.

Configuration information includes, but is not limited to, some or all of the following:

indication information of an area where the auxiliary information is to be reported, such as an area number or a GPS coordinate of a plurality of points on a boundary corresponding to the area;

the auxiliary information reporting triggering mode, such as periodic reporting or event triggering reporting or both, is supported;

if the configuration period is reported, the corresponding period is also needed to be reported. The specific period may be a period of a time dimension, for example, reporting once every several times (for example, 10 seconds); or a period of a spatial dimension, for example, the V2X terminal moves a certain distance (for example, 10 meters) and reports once.

If the reporting is triggered by the configuration event, the corresponding event also needs to be configured, for example, the PC5V2X message is sent and/or received N times (N > -1), the reporting of the auxiliary information is triggered; or the distance from the terminal V2X to the last reporting position exceeds M meters (M > -1), triggering the auxiliary information reporting.

And step 3: the V2X terminal records side information (here, the V2X terminal includes a V2X terminal at a transmitting end and/or a V2X terminal at a receiving end).

The mode of recording the auxiliary information by the V2X terminal includes but is not limited to part or all of the following modes:

the first method is as follows: and recording according to the period appointed by the protocol or the period configured by the base station.

The specific period may be a period of a time dimension, such as recording the auxiliary information once every several times (e.g. 1 second); it may also be a period of spatial dimension, for example, when the V2X terminal moves a certain distance (for example, 1 meter) to trigger one-time recording of the auxiliary information.

The second method comprises the following steps: the V2X terminal makes recordings based on events.

Specifically, the V2X terminal may record the auxiliary information each time it transmits or receives; it is also possible to record the auxiliary information with a terminal position interval exceeding X meters at the time of two transmissions or two receptions or one transmission and one reception.

The auxiliary information content recorded by the V2X terminal at the transmitting end includes, but is not limited to, some or all of the following information:

PC5V2X transmission identity, time when V2X terminal transmits PC5V2X message, location information when PC5V2X message is transmitted (location information may be GPS coordinates or area number).

The auxiliary information content recorded by the V2X terminal at the receiving end includes, but is not limited to, part or all of the following information:

the PC5V2X received identification, the time when the V2X terminal received the PC5V2X message, the location information (the location information may be GPS coordinates or an area number) when the PC5V2X message was received, and the identification of the transmitting terminal to which the received PC5V2X message corresponds.

In implementation, the identity can be sent as a PC5V2X or received as a PC5V2X with a 1-bit identity, i.e. 1bit indicates whether it is a sender or a receiver.

And 4, step 4: and the V2X terminal reports the auxiliary information according to the configuration information.

Before reporting the auxiliary information according to the configuration information, the V2X terminal may determine whether the terminal is located in an area where the auxiliary information is to be reported, and if so, determine according to the configuration information sent by the base station in step 2:

if the configuration period is reported, the V2X terminal firstly reports the auxiliary information once entering the area where the auxiliary information is to be reported, and starts a periodic timer, and triggers the auxiliary information reporting once the timer is overtime.

If the configuration event triggers the reporting, the V2X terminal triggers the reporting of the auxiliary information once entering the area where the auxiliary information is to be reported and meeting the event configured by the base station.

The auxiliary information reported to the base station may be all or part of the auxiliary information recorded by the V2X terminal.

If the auxiliary information is part of the auxiliary information, multiple intercepting modes can be provided, for example, the auxiliary information recorded for the nearest N times from the reporting time or the auxiliary information recorded within a time period of < T from the reporting time interval can be intercepted.

Optionally, step 5: the base station determines whether the auxiliary information needs to interact with an adjacent base station.

In the first mode, if the auxiliary information received by the cell a of the base station and reported by the V2X sending terminal or exchanged by the neighboring base stations includes the area managed by the cell B, the auxiliary information needs to be forwarded to the cell B through the inter-base station interface. The whole piece of auxiliary information may be forwarded during forwarding, or only the auxiliary information related to the cell B may be extracted.

In the second mode, if the auxiliary information of the auxiliary information reported by the V2X receiving terminal or exchanged by the neighboring base stations received by the cell a of the base station includes the management of the cell B and the neighboring area (the so-called neighboring area, that is, the area in the cell B that the signal sent by the V2X sending terminal PC5 can cover but does not belong to the cell B), the auxiliary information needs to be forwarded to the cell B through the inter-base station interface. The whole piece of auxiliary information may be forwarded during forwarding, or only the auxiliary information related to the cell B may be extracted.

Step 6: and exchanging auxiliary information between the base stations.

If it is determined in step 5 that the assistance information needs to be exchanged between the adjacent cells, the adjacent base stations may exchange the assistance information determined in step 5 that needs to be exchanged through an inter-base station interface.

In implementation, after a period of time for reporting the auxiliary information, if the base station can relatively accurately determine the Uu V2X target area that needs to be used, the base station may notify the V2X terminal to stop reporting the auxiliary information through broadcasting. When the need arises, the terminal starts the auxiliary information reporting again through the broadcast notification V2X (for example, the base station verifies whether the previously determined Uu V2X target area needs to be modified once every several times).

Example 2: auxiliary information configuration and reporting process (special signaling mode)

As shown in fig. 10, a second method for reporting auxiliary information according to the embodiment of the present invention includes:

In implementation, the base station determines whether there is prior information (such as map information);

Step 2: and the base station sends the configuration information required for reporting the auxiliary information to the V2X terminal in the area through special signaling.

RRC signaling, MAC signaling, physical layer signaling.

Step 6: and exchanging auxiliary information between the base stations.

In implementation, after a period of time for reporting the auxiliary information, if the base station can accurately determine the Uu V2X target area that needs to be used, the base station may notify the V2X terminal to stop reporting the auxiliary information through a dedicated signaling. When necessary, the V2X terminal is notified by dedicated signaling to start the secondary information reporting again (for example, the base station verifies whether the previously determined Uu V2X target area needs to be modified once every several times).

From the above, it can be seen that: according to the method, the network side equipment generates communication mode switching information according to the target area of the target communication mode in V2X communication; sending the communication mode switching information to the V2X terminal; the target communication mode is a Uu V2X communication mode or a PC5V2X communication mode. Because the communication mode is switched according to the target area, the communication mode switching in V2X communication is realized, and the V2X communication performance is improved.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
