Specific embodiment

To guarantee that message is sent to all correlation UE in periphery, a kind of possible mode is exactly by car networking and Mesh network (i.e. " wireless mesh network ", it is " multi-hop (multi-hop) " network) combines.Mesh network be a kind of dynamic, self-organizing, The multi-hop broadband wireless network of self-configuring.Node in Mesh network can be divided into three categories:

MPP (Mesh Portal Point): wired portal node in Mesh network, for wireless Mesh netword and wired Network connection carries out data communication by the node and external network.

MP (Mesh Point): the node of Mesh network function, the communication node between Mesh network are supported between node automatic The functions such as topology, the automatic discovery of routing, data packet forwarding.

MAP (Mesh Access Point): MAP node is referred to as Mesh agency, is that STA (Station, platform) enters net The bridge of network.

Existing Mesh network establishment process includes following three big steps:

Step 1:Mesh neighbours discovery.MP passes through active transmission Mesh Probe Request probe request, or passive Mesh Beacon (beacon) frame is listened to, to collect neighbor information.

Step 2:Mesh connection creation and deletion process.Both sides are by the way that Peer Link Open (beat by peer link twice Open) interaction of/Confirm (confirmation), complete Mesh establishment of connection.

Step 3:Mesh Route establishment.

If Mesh establishment process directly applied in car networking environment, need to carry out information exchange ability between vehicle vehicle Set up Mesh network.And before establishing Mesh network, the role of each UE requires clear.It i.e. will be true when UE dispatches from the factory Determine the corresponding role of each UE, is MP, MAP or STA.This will imply that certain UE will certainly be always with high-power operation (MP/MAP), certain UE (STA) do not need that other UE is helped to forward data always.For the reasonable employment for guaranteeing oneself power, very More UE can occur with the role of STA, and be reluctant as MP/MAP.Without MP/MAP, Mesh network will be difficult to construct.In addition to UE Role configures unfair outer, Mesh network is established between vehicle vehicle will lead to some regions and only have STA to forward without MP/MAP etc. Node will lead to the problem of message cannot be forwarded.

Exemplary embodiments of the present disclosure are described in more detail below with reference to accompanying drawings.Although showing the disclosure in attached drawing Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure It is fully disclosed to those skilled in the art.

Referring to Fig. 3, the multi-hop transmission method for being suitable for vehicle connection multihop network of one embodiment of the invention is shown in figure, it should The executing subject of method can be base station, the specific steps are as follows:

Step 301 determines role of the present terminal UE in vehicle connection multihop network；

It should be noted that the role of the UE in vehicle connection multihop network is not fixed in embodiments of the present invention.Join in vehicle When multihop network constructs, the role of the UE in vehicle connection multihop network can be determined, naturally it is also possible to be updated to vehicle connection multihop network When, determine the role of the UE in vehicle connection multihop network.

By the vehicle connection multihop network be vehicle join Mesh net for, due to vehicle connection multihop network in UE role be not it is fixed, Certain UE are avoided always with high-power operation (MP/MAP), and certain UE (STA) do not need that other UE is helped to forward data always The problem of, that is, it avoids UE role and configures unfairness.Further, it avoids establishing Mesh network between vehicle vehicle and will lead to some districts The problem of domain only has STA without forward node such as MP/MAP, causes message that cannot be forwarded.

Role of the current UE in vehicle connection Mesh net can be any one in MP, MAP, STA, wherein if current UE Role in vehicle connection Mesh net is MP or MAP, which has the ability of forwarding message；If current UE is in vehicle net Role be STA, then the current UE do not have forwarding message ability, at this point, the current UE can be by sending a message to Base station, by the base station broadcast message, then other UE by receiving the message are forwarded message.

In embodiments of the present invention, base station can determine angle of the current UE in vehicle connection multihop network by following two mode Color:

Mode 1 determines role of the current UE in vehicle connection multihop network by the configuration message between adjacent base station；

Mode 2 determines that current UE joins in multihop network in vehicle by network environment and/or UE ability (UE Capability) Role.Above-mentioned network environment can be the position of UE in coverage area；Above-mentioned UE ability can be to aid in other UE forwarding numbers According to ability, be also not limited to this certainly.

Step 302 determines multi-hop transmission range or multi-hop number of the message of current UE in vehicle connection multihop network；

Base station under multi-hop transmission mode not instead of traditional sense and the direct communication between mobile subscriber, information source is by one A or multiple fixations or mobile relay node transmits its information to destination node (stay of two nights), it is mainly characterized by handle Direct transmission path under traditional sense is divided into multiple short and small paths to transmit information source information.

Above-mentioned multi-hop transmission Range Representation message needs the range being forwarded.Such as when receiving the adjacent UE of the message and work as When the difference of the distance between preceding UE and multi-hop transmission range is less than or equal to zero, the adjacent UE auxiliary for receiving the message forwards this to disappear Breath；Otherwise, the adjacent UE for receiving the message does not have to auxiliary and forwards the message, wherein adjacent UE is the adjacent UE of current UE.

Above-mentioned multi-hop number indicates forwarding message by the number of relay node (vehicle joins other UE in multihop network).Such as When the message is often forwarded once, which needs to subtract a preset value (such as the preset value is 1), receives message Adjacent UE can judge whether to need to assist to forward the message based on the multi-hop number.If multi-hop number is greater than zero, receive The adjacent UE auxiliary of the message forwards the message；If multi-hop number is less than or equal to zero, the adjacent UE for receiving the message does not have to auxiliary Forward the message.

Specifically, in embodiments of the present invention, base station can need to pass using multi-hop transmission mode in the following manner When the message of defeated current UE, multi-hop transmission range or multi-hop number of the message in vehicle connection multihop network are determined: if current UE Resource distribution mode, the covering demand of position, request message that base station is reported based on current UE are dispatched using based on base station With it is one or more in the movement speed of current UE, determine multi-hop transmission range or multi-hop number.

Transfer resource needed for step 303, determining transmission message；

In embodiments of the present invention, base station can determine in the following manner need to transmit using multi-hop transmission mode it is described Transfer resource needed for message: if current UE dispatches resource distribution mode using based on base station, base station is adopted for current UE The message allocation of transmission resources is transmitted with multi-hop transmission mode, and the transfer resource is handed down to the current UE, it is optional Ground, transfer resource be single transmission resource, be transmitted several times resource or be current UE distribution continuous time in resource.

Step 304, according to the role of current UE and the role of current UE and transfer resource, by the position of the message, current UE It sets and multi-hop transmission range or the message and multi-hop number is transferred to the adjacent UE adjacent with current UE, by adjacent UE according to working as The position of preceding UE and multi-hop transmission range or multi-hop number judge whether that adjacent UE auxiliary is needed to forward the message.

In embodiments of the present invention, whether adjacent UE can be judged by the following manner needs its auxiliary to forward the message:

If mode 1, multi-hop number are greater than zero, determined to need its auxiliary forwarding message by adjacent UE；If multi-hop number Equal to zero, then its auxiliary forwarding message is not needed by adjacent UE judgement, wherein message is often forwarded once, and multi-hop number subtracts one Preset value (such as the preset value is 1)；

Mode 2 judges whether neighbour the distance between UE and current UE and the difference of multi-hop transmission range are less than by adjacent UE In zero, if difference is less than or equal to zero, determined that its auxiliary is needed to forward the message by adjacent UE；Otherwise, sentenced by the neighbour UE Surely it does not need its auxiliary and forwards the message.

In embodiments of the present invention, the transmission range of message in car networking is increased by multi-hop transmission, it is ensured that current UE Surrounding UE can receive the current UE sending message.

Referring to fig. 4, the multi-hop transmission method for being suitable for vehicle connection multihop network of one embodiment of the invention is shown in figure, it should The executing subject of method can be current UE, the specific steps are as follows:

Step 401 determines role of the current UE in vehicle connection multihop network；

Role of the current UE in vehicle connection multihop network can be any one in MP, MAP, STA, wherein if current UE Role in vehicle connection multihop network is MP or MAP, which has the ability of forwarding message；If current UE is in vehicle net Role be STA, then the current UE do not have forwarding message ability, at this point, the current UE can be by sending a message to Base station realizes the forwarding of message by base station and other UE.

In embodiments of the present invention, current UE can determine current UE in vehicle connection multihop network by following two mode Role:

Mode 1, current UE obtain base station and notify its role in vehicle connection multihop network, which is by between adjacent base station Configuration message determine current UE vehicle connection multihop network in role；

Mode 2, current UE obtain base station notify its vehicle connection multihop network in role, the base station by network environment and/ Or UE ability (UE Capability) determines role of the current UE in vehicle connection multihop network.Above-mentioned network environment can be covering The position of UE in range；Above-mentioned UE ability can be to aid in the ability of other UE forwarding data, be also not limited to this certainly.

Step 402 determines multi-hop transmission range or multi-hop number of the message of current UE in vehicle connection multihop network；

For example, one in the covering demand of position, message based on current UE and the movement speed of the current UE or It is multinomial, determine multi-hop transmission range or multi-hop number.

Transfer resource needed for step 403, determining transmission message；

In embodiments of the present invention, current UE can be determined by following two kinds of modes and need to pass using multi-hop transmission mode Transfer resource needed for the defeated message:

If mode 1, current UE independently select resource distribution mode using based on the current UE, current UE is based on Transmission needed for the transmission resource pool determination that base station is broadcasted in system information transmits the message using multi-hop transmission mode provides Source；

If mode 2, current UE using based on base station dispatch resource distribution mode, or if current UE use It is that resource distribution mode is independently selected based on the current UE, current UE is determined based on the private resource pond that base station is distributed using more Jump transfer resource needed for transmission mode transmits the message.

Step 404, the role according to current UE and the transfer resource pass message, the position of current UE and multi-hop Message and multi-hop number are transferred to the adjacent UE adjacent with the current UE by defeated range, by the neighbour UE according to current UE Position and multi-hop transmission range or multi-hop number judge whether that adjacent UE auxiliary is needed to forward the message.

Referring to Fig. 5, a kind of process of multi-hop transmission method is shown in figure, the executing subject of this method is neighbour UE, specifically Steps are as follows:

Step 501 receives message, the current UE that current UE is sent according to the role of the current UE and transfer resource Position and multi-hop transmission range or the message and multi-hop number；

Step 502 carries out auxiliary forwarding according to the position of the current UE and multi-hop transmission range or multi-hop number The message.

In embodiments of the present invention, optionally, it is described according to the position of the current UE and multi-hop transmission range or Multi-hop number carries out auxiliary and forwards the message, comprising:

In embodiments of the present invention, optionally, the forwarding message, comprising:

In embodiments of the present invention, optionally, according to the position of the current UE and multi-hop transmission range or multi-hop Number carries out auxiliary and forwards the message, comprising:

Judge whether to receive the multi-hop number；

Judge whether the difference is equal to zero；

Referring to Fig. 6, the multi-hop transmission method for being suitable for vehicle connection multihop network in another embodiment is shown in figure, it is specific to walk It is rapid as follows:

Step 601, multihop network building update.

Above-mentioned multihop network can be vehicle connection Mesh network, and vehicle connection Mesh network refers to the Mesh constructed by car-mounted terminal Network.In order to make it easy to understand, being below that vehicle connection Mesh network is illustrated with the multihop network.

Such as: base station joins in Mesh network UE (can be understood as vehicle and join multi-hop network termination) in vehicle by configuring message Role configures, to construct vehicle connection Mesh network or update to vehicle connection Mesh network.

The UE for only belonging to vehicle connection Mesh network just has the ability of forwarding, and hereinafter referred to as such UE is Mesh UE.Such as figure Shown in 7, multiple Mesh UE construct a Mesh network, and each Mesh UE can forward multi-hop data, other UE cannot be assisted Forward multi-hop data.

Vehicle joins Mesh network initialization procedure can voluntarily be determined by some base station, can also be by between adjacent base station V2X configuration information is negotiated to determine, referring to Fig. 8.

Vehicle connection Mesh network can be divided into multiple by geographical location, or one.Vehicle joins Mesh network may be simultaneously Some base station (referring to Fig. 8) is not belonged to, i.e., a vehicle connection Mesh network can be across all base stations of current operator, can also It can also include a part of coverage area of base station to only include the coverage area of several base stations.

In embodiments of the present invention, base station can join Mesh for the geographical location of UE in coverage area, dynamic configuration vehicle Network.Optionally, base station is the mark (Mesh_id) and each vehicle connection that each vehicle joins that Mesh network distributes vehicle connection Mesh network Transfer resource needed for Mesh network, each vehicle join the V2X configuration that each Mesh UE in Mesh network can be sent from base station The vehicle connection Mesh network belonging to oneself is known in information.

In embodiments of the present invention, base station can realize that vehicle joins the update of Mesh network by V2X configuration information update.

Optionally, update can be recurrent, be also possible to event triggering, such as some Mesh UE and other Mesh UE is more and more remoter, so that having exceeded the range of multi-hop data transmission, can trigger more new car at this time and joins Mesh network.

Step 602 determines whether the transmission of message to be transmitted uses Mesh multi-hop transmission mode and corresponding multi-hop to pass Defeated range (Mesh_range) or multi-hop number (Multi_Hop_Counter).

Above-mentioned message to be transmitted refers to the message needed in vehicle connection Mesh network transmission.For example, can be according to the class of message Type determines whether the message to be transmitted uses Mesh multi-hop transmission mode, if necessary to use Mesh multi-hop transmission mode, then again Further determine that Mesh_range or Multi_Hop_Counter, wherein if the type of message is V2X type, then it represents that need To use Mesh multi-hop transmission mode.

Optionally, Mesh_range or Multi_Hop_Counter can based on UE movement speed, the present position UE and One or more determinations in the information such as the covering demand of request message, wherein UE movement speed it is corresponding carry the UE vehicle Travel speed；The present position UE includes: position of the UE in vehicle connection Mesh network；The covering demand of request message is used for It indicates no to need to transmit the message in a big way, that is to say, that current Mesh UE needs message to be transmitted being transmitted to vehicle Join other MeshUE in Mesh network.

In embodiments of the present invention, Mesh_range or Multi_Hop_Counter can both be determined by base station, can also be with It is determined by UE, concrete mode is as follows:

Mode 1: if current UE dispatches resource distribution mode using the base station based on PC5 mouthfuls, base station is based on current The information such as the covering demand of the present position UE, request message that UE is reported, current UE movement speed determine the biography of message to be transmitted It is defeated whether to use multi-hop mode, and determine Mesh_range or Multi_Hop_Counter.

Wherein, Mesh_range or Multi_Hop_Counter can pass through PDCCH (PhysicalDownlink Control Channel, Physical Downlink Control Channel) control signaling is handed down to UE, or can also be issued by broadcast mode. At the same time, base station needs the transmission for current UE this time message to be transmitted to distribute corresponding transfer resource, which can be with For single transmission resource, it is also possible to that resource is transmitted several times, can also be one section of continuous time transfer resource.

Mode 2: if current UE independently selects resource distribution mode using the UE based on PC5 mouthfuls, current UE is based on The information such as itself present position, the covering demand of request message, current UE movement speed determine whether using multi-hop mode, and really Determine Mesh_range or Multi_Hop_Counter.

It should be noted that above-mentioned current UE can be Mesh UE, or the STA without forwarding capability.

Step 603 determines the transfer resource for needing the V2X message of multi-hop transmission.

In embodiments of the present invention, transfer resource can be obtained by following four kinds of modes:

Mode 1: if current UE dispatches resource distribution mode using the base station based on PC5 mouthfuls, base station needs for UE The V2X message distribution respective resources for needing multi-hop transmission of this time transmission, which can be single transmission resource, be also possible to Resource is transmitted several times, can also be the resource in the continuous time for UE distribution.The transfer resource passes through under PDCCH control signaling Issue UE.

Mode 2: if current UE independently selects resource distribution mode using the UE based on PC5 mouthfuls, UE if, is based on base The transmission resource pool broadcasted in system information of standing determines transfer resource.

Mode 3: base station can also join Mesh network for vehicle and provide dedicated transmissions resource pool, which, which can pass through, is Information of uniting informs UE, can also inform UE in V2X configuration by proprietary signaling.

Regardless of current UE independently selects resource distribution mode using base station scheduling resource distribution mode or UE, The private resource pond that can be distributed based on base station determines this message transport resources.

Mode 4: if UE by the V2X information reporting to base station, base station can also be transmitted the needs by broadcast mode Message issues.Transfer resource is the broadcast resource for being only applicable to the transmission of this message at this time.

Step 604, current Mesh UE broadcast Mesh_ in SA (Scheduling Assignment, schedule job) Range and current Mesh UE location information or Multi_Hop_Counter, to inform that the neighbour Mesh UE message needs it Auxiliary forwarding.

Assuming that current Mesh UE uses the resource distribution mode of base station scheduling, if base station is that Mesh UE is only assigned with list Secondary transfer resource, then current Mesh UE sends the message in this resource；If base station is that Mesh UE is assigned with multiple biography Defeated resource, then remaining distribution resource can also be referred to by SA after current MeshUE sends the message in the resource of distribution Show to adjacent Mesh UE, in order to which adjacent Mesh UE sends the message faster, without to base station requests transfer resource.

Assuming that the resource distribution mode that current Mesh UE uses UE independently to select, Mesh UE independently select resource to forward SA and data.

If issuing the message by the way of base station broadcast in step 603, base station can broadcast Mesh_ simultaneously Range and the UE location information, current Mesh UE are not necessarily to any operation.

Step 605, neighbour Mesh UE judge whether to need its auxiliary forwarding based on the information received, if necessary to just exist It is forwarded in respective resources.

Adjacent Mesh UE receives the V2X message and Multi_Hop_Counter (> 0), just by Multi_Hop_ Counter subtracts 1, then forwards.If Multi_Hop_Counter=0 when neighbour UE receives the V2X message, without forwarding. Or neighbour Mesh UE receives the V2X message, the position UE and Mesh_range, more adjacent Mesh UE is away from the position UE received Distance-mesh_range≤0, only when inequality set up when its just assist V2X message forwarding.

If neighbour Mesh UE is configured to the resource distribution mode of base station scheduling, and does not receive previous dive MeshUE and send Available resources, then its need to base station requests send resource to forward the message；

If neighbour Mesh UE is configured to the resource distribution mode of base station scheduling, and receive that previous dive Mesh UE sends can With resource, then neighbour Mesh UE can forward the message with the available resources, and when there is residue transmission resource by residue transmission Resource is indicated to next-hop Mesh UE；

If neighbour Mesh UE is configured to UE and independently selects resource mode, and do not receive that previous dive Mesh UE sends can With resource, then it directly transmits the V2X message after sensing.

If neighbour Mesh UE is configured to UE and independently selects resource mode, and receives the available money that previous dive Mesh UE is sent Source then it directly transmits the message after sensing or directly sends the message in available resources, and ought have remaining biography Residue transmission resource is indicated to next-hop Mesh UE when defeated resource.

After step 606, the Mesh UE adjacent with neighbour Mesh UE receive the V2X message for needing multi-hop transmission, continue to execute Step 605.

Referring to Fig. 9, a kind of mixed transport scheme based on Uu mouthfuls of broadcast and PC5 mouthfuls of multi-hops is shown in figure.

If the V2X message has been sent to base station by Uu mouthfuls by current Mesh UE, base station is potentially based on working as of receiving The message that preceding UE is sent, and the information such as the covering demand of the position, request message reported according to UE, UE movement speed determine whether Using Mesh multi-hop mode, and determine Mesh_range.

Base station determines the Mesh network of V2X message forwarding, and issues the V2X message in a broadcast manner, while indicating phase It closes Mesh UE needs to be forwarded the V2X message, and provides relevant parameter (position mesh_range, UE etc.).

Location information of the Mesh UE based on own location information and Mesh_range, the UE for receiving message, determination are It is no to need to be forwarded for the V2X message.Only work as inequality: distance-of the Mesh UE away from the position UE for receiving message Mesh_range≤0 sets up the forwarding of Shi Qicai auxiliary data.
