The method for service sending, provided by the invention, comprises the following steps: a local node determines a specific time slot used for sending the specific service during each frame period according to sending time delay and frequency of the specific service to be sent; the local node sends a reservation message used for specifying the specific time slot occupied by the local node in each frame period to other nodes; when the specific time slot is up, and when other nodes confirms that the local node can occupy the specific time slot of each frame period, the local node sends the specific service in the specific time slot of each frame period.
Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of method for transmitting service and device.
Background technology
In MANET, use (Mobile Slotted ALOHA, MS-ALOHA) during Access Algorithm, between node, periodically send frame information (Frame Information, FI), to realize each node awareness network topology and occupation condition, and in the priority state territory of FI, defined 2 bits and illustrated that node sends the priority of data, provide high-priority data and seized the fundamental mechanism of lower-priority data, and the classification that has provided the corresponding priority state of a kind of business is advised, according to emergency vehicle, safety, auxiliary and amusement respectively corresponding service priority is arranged from high to low, do not consider time delay and send the characteristics such as frequency business is classified, and some business is high to delay requirement in car networking, sending frequency requires also high, for example, the forward direction perception use-case that between vehicle, cooperation collision alleviates to delay requirement within 20ms, and according to the frequency of 50Hz, carry out periodic broadcast within certain effective time, according to current MS-ALOHA priority preemption mechanism, do not provide for delay requirement high, send how Gains resources of business that frequency is high.
Introduce MS-ALOHA resource occupation fundamental mechanism below:
MS-ALOHA is access and the resource allocation mechanism based on TDMA.Each frame consists of N time slot, wherein, N is positive integer, on each time slot, can only there is 1 node to send, when node sends information on time slot, in information, carry FI(frame information), wherein FI is comprised of N territory, the corresponding time slot in each territory, embodies the state of this time slot of sending node perception.The FI information that each node sends by processing other nodes, obtains time slot service condition around, thereby realizes slot reservation effect when distributed.
In MS-ALOHA, when new node adds network, first to obtain time interval resource.As shown in Figure 1, node completes channel occupancy process by 5 steps: monitor, select free timeslot, wait and confirm this time slot free time, transmission, monitoring feedback.Each step is specific as follows:
Step 1: monitor a frame
First node monitors all time slots in a frame, and information is inserted in the time slot state cache table of oneself.After a frame end, node has obtained the time slot state information of own maintenance, and performs step two.
Step 2: select a free timeslot
For certain time slot, only, when this time slot identifies the free time in time slot state cache table, think that this time slot is idle available: if available free time slot is selected this time slot; If free timeslot is more than one, therefrom select at random one; If there is no free timeslot, so the time slot lower than own current priority selected as free timeslot.Select after free timeslot execution step three.
Step 3: wait for that selected time slot arrives, whether idlely reaffirm
Suppose in step 2 the idle slot p of selection.Before slot p arrives, continue to monitor each time slot so, in window, remain the information of a nearest N slot.By the time the ending of slot p-1, utilizes time slot state cache table, checks whether slot p still meets the condition (mode that the priority while comprising without idle slot is considered) in step 2:
As met, perform step four.
If do not met, perform step immediately two this moment.
Step 4: send information at slot p, and fill in the territory in FI, after being sent, empty time slot state cache table, execution step five.
Step 5: monitor feedback, be confirmed whether successfully: from slot p+1, monitor N-1 time slot, generate time slot state cache table, in the ending of slot p+N-1, judge that whether slot p is successful.
Under normal circumstances, in data transmission procedure, if node is not initiatively abandoned the time interval resource of having safeguarded, can use the slot transmission data that take, other nodes can not be used this time slot in the meantime always.
About FI message, be described below:
Each activates node and is sent with fixed news institutional framework FI message and indicated by periodicity, from the angle of this node, thinks that time slot allocation takies situation.In each frame, on the time interval resource that node all must take at oneself, send FI message, and according to the FI of neighbors and the own channel usage Time Slot Occupancy state that upgrades in time, and the Time Slot Occupancy state after upgrading is embodied in the FI message of oneself transmission.
FI form:
In MS-ALOHA, every N time slot forms a frame, and FI is a vector being comprised of N time slot state message, and the FI message in top n time slot, other-end being sent by node oneself is monitored and obtained.In the FI message that node sends, the state indication message of each time slot consists of 12bit, is respectively:
Time Slot Occupancy state indication message (2bit): time slot state in FI, is defined as: idle condition (00), seizure condition (10), conflict situation (01), double bounce seizure condition (11).
Take the temporary mark (Source Temporary Identifier, STI) of corresponding time slot terminal (8bit)
Send the priority indication (2bit) of data: defined four grades, and provided following suggestion:
PSF=[00]-Emergency, only to emergency vehicle, use, each emergency vehicle can only take 1 time slot for this object.
PSF=[01]-Safety, for the communication of the general road safety object of common vehicle.Each car is set up the Traffic Channel for the communication of general road safety object after startup.Each vehicle can only take 1 time slot for this object.
PSF=[10] – Auxiliary, for auxiliary object (concrete meaning is not clear and definite), each vehicle can only take 1 time slot for this object.
PSF=[11]-Entertainment, for the communication of amusement object, each vehicle can take a plurality of time slots for this object.
Therefore, in each time slot, need the FI message of transmission to need altogether 12 * N bit.
When terminal monitoring arrives the FI message of other-end transmission, need to be according to the seizure condition that receives each time slot of content update of FI.
Node, according to the FI message receiving in former frame length, is determined the seizure condition of each time slot in this frame, generates corresponding FI.FI message makes node can grasp the distribution condition of (three jump Radio Resource in addition can be multiplexing) time slot within the scope of three jumpings, safeguards the time interval resource oneself taking, and reduces conflict, improves resource utilization.
About business, seize and be described below:
The data that in MS-ALOHA, node will be sent have been divided into four grades, each node indicates with 2bit the priority that each time slot sends data in FI message, but clearly do not provide illustrating of Data classification, only provide the classification of a suggestion, with reference to the PSF definition in above-mentioned FI form.When node A need to send the data of high priority, first monitor a frame period, after knowing the seizure condition of current time slots, select a free timeslot, if all time slots are all scheduled, be chosen in the upper data that send of time slot j that send the Node B place that priority data is low, cause this time slot collision, during other node feedback acknowledgments, think that time slot j is taken by A, when Node B is received the FI of other nodes, will appreciate that and on time slot j, have the business of individual high priority to seize this time slot, Node B will discharge this time slot j, wait for new free timeslot access.
In sum, existing MS-ALOHA business preemption mechanism has provided the classification suggestion of the corresponding priority state of business: according to emergency vehicle, safety, auxiliary and amusement service priority is from high to low arranged, although understand when without free timeslot, the node that sends the business of high priority can be seized the node that sends low priority traffice, guaranteed that high-priority service is subject to can preferentially send at time interval resource in limited time, but do not consider time delay and send the demand that the characteristics such as frequency send business in business classification suggestion, therefore higher for delay requirement, send the high application scenarios of frequency, the forward direction perception use-case delay requirement alleviating as cooperation collision between vehicle is within 20ms, and according to the frequency of 50Hz, carry out periodic broadcast within certain effective time, if adopt existing MS-ALOHA priority preemption mechanism, can not be in 20ms obtain time interval resource, and periodically send within a certain period of time with the transmission frequency of 50Hz.
Therefore, the specific (special) requirements sending in order to meet the vehicle message of the business that sends low time delay, high frequency, need to be optimized design for the resource reservation mechanism of such business.

Embodiment
The embodiment of the present invention provides a kind of method for transmitting service and device, in order to realize the transmission of the specific transactions of low time delay, high frequency, guarantees that delay performance requires high business reliably to obtain time interval resource and meets the performance requirement of business.
Specific transactions described in the technical scheme that the embodiment of the present invention proposes, is the business of low time delay, high frequency, and for example, transmission delay requires within 20ms, and within certain effective time, according to the frequency of 50Hz, carries out the business of periodic broadcast.
In the embodiment of the present invention, need to send the node of low time delay, high frequency business according to low time delay, the high frequency service feature that will send, after this business data packet arrives, in meeting delay requirement, send this business data packet, and within a frame period, preengage the business data packet that a plurality of time slots send this low time delay, high frequency;
The node of non-low time delay, high frequency business receives after the time interval resource subscription information that sends low time delay, the transmission of high frequency service node, and whether the time interval resource of judgement reservation is own current time interval resource, if so, discharges the time interval resource of oneself.Otherwise, to upgrade own current time slot maintenance state table, and on the time slot occupying at oneself, send renewal FI message, indication sends the selected time slot of node (can be referred to as particular time-slot in the embodiment of the present invention) of this low time delay, high frequency business.
The technical scheme embodiment of the present invention being provided below in conjunction with accompanying drawing describes.
Referring to Fig. 2, a kind of method for transmitting service that the embodiment of the present invention provides, comprises step:
The transmission delay of the specific transactions that S101, local node send as required and frequency, determine in each frame period for sending the particular time-slot of this specific transactions;
Wherein, described particular time-slot comprises for sending the initial time slot of specific transactions and a plurality of time slots of follow-up reservation.The selection of a plurality of time slots of initial time slot and follow-up reservation can consider that sending node transmission processing time, receiving node reception & disposal time, sending node and receiving node communications time, free timeslot, node have taken time slot, sent the factors such as frequency interval.
S102, local node send to other nodes by the reservation message that is used to indicate this local node and need to takies described particular time-slot within each frame period;
Wherein, described other nodes, refer to all nodes except local node in network, because all nodes all will be monitored and dodge local node and need to take for sending the resource of the particular time-slot of this specific transactions.
S103, when described particular time-slot arrives, and described other nodes are while confirming that described local node can take described particular time-slot within each frame period, the particular time-slot of local node within each frame period sends this specific transactions.
In network, all nodes all feed back the time slot of local node reservation, and after feeding back successfully, within the effective time of follow-up this business, local node sends this business on the time slot of reservation.
Preferably, the priority indication information that also comprises described specific transactions in described reservation message.
System is high-priority service by, the high business setting of transmission frequency higher to delay requirement, the sign of this high-priority service can, with the priority indication (as PSF=00) of the transmission data of existing MS-ALOHA 2bit, also can define new information unit.
Preferably, described reservation message, is frame information FI message, or takies message for special-purpose application.
Node, when sending the high-priority service of low time delay, high frequency, according to sending frequency, is preengage a plurality of time slots and is sent, and slot time meets the transmission frequency of this business.Preengage the mechanism of a plurality of time slots, can directly in time slot, by FI, preengage, the special use application that also can send a plurality of time slots of reservation takies message, and local node sends to other nodes by the reservation message that is used to indicate this local node and need to takies described particular time-slot within each frame period.
Preferably, described reservation message, sends to other nodes by high-priority service access slot or described particular time-slot.
Wherein, what high-priority service access slot was system configuration is the special reserved time interval resources of some special applications, can take request message for sending the node transmission of high-priority service.System is according to business demand, configurable a plurality of high-priority service access slots.
If be provided with high-priority service access slot in system in advance, described reservation message is at this high-priority service access slot, to send separately, and in order to increase transmission reliability, simultaneously own preengage for sending, the particular time-slot of specific transactions sends together with particular traffic data; If be not provided with high-priority service access slot in system in advance, only own preengage for sending, the particular time-slot of specific transactions sends together with particular traffic data.
Preferably, described reservation message, repeats to send.
Preferably, when other nodes confirm that described local node can not take described particular time-slot within each frame period, the method also comprises:
Local node is according to up-to-date frame information FI, and the frequency of described specific transactions, redefines in each frame period for sending the particular time-slot of this specific transactions.
Referring to Fig. 3, node receives at TSi the packet that high level will send the high-priority service of low time delay, high frequency, node is chosen in TSk and starts to send this packet, preengage other a plurality of time slot TSm etc., the factors such as node transmission processing time, receiving node reception & disposal time, sending and receiving node communication transmission time, free timeslot, transmission frequency interval are considered in the selection of the time slots such as TSk, TSm simultaneously.
If send the existing time slot that takies of node of the high-priority service of low time delay, high frequency, consider above-mentioned factor, meeting in low time delay and frequency interval situation, can preferentially be chosen in the business data packet that sends low time delay, high frequency on the time slot having taken; Otherwise the former time slot that takies still sends former business data packet.In these two kinds of situations, node all upgrades the time slot state table of oneself former taking on time slot, sends the FI message of upgrading.
If system is provided with high-priority service access slot, send the special use application that the node of the high-priority service of low time delay, high frequency can send a plurality of time slots of reservation at the high-priority service access slot of system and take message, to strengthen the reliability of time slot reservation.The application that this node sends on high-priority service access slot takies message can be before initial time slot, also can be after initial time slot.While having a plurality of high-priority service access slot in system, in order to strengthen the reliability of reception, can repeat to send application at each high-priority service access slot and take message.The form that special-purpose application takies message can adopt the form of similar FI message, also can be other signaling format or message format, in this message, can indicate the ID of the high-priority service of low time delay, high frequency, need the new time slot of selecting and the time slot mark having taken, can also comprise safety verification etc. other self message.
In said process, the high-priority service node of non-low time delay, whether the time interval resource of judgement reservation is own current time interval resource, if so, discharges the time interval resource of oneself; Otherwise, upgrade own current time slot maintenance state table, indication sends the selected time slot of high-priority service node of low time delay, high frequency.
If send the high-priority service node of low delay requirement, high frequency by monitoring after the own time slot reservation success of feedback and judge, just effectively continuing to send FI and relevant service message in the time on the time interval resource of reservation subsequently; Otherwise time slot reservation failure, then according to up-to-date FI information, again preengages multi-slot and sends the business data packet of low time delay, high frequency.
Provide the introduction of several specific embodiments below:
Embodiment 1: system is without high priority access slot, and vehicle need to send low time delay, send the high high-priority service of frequency, but the former time slot that takies does not meet the embodiment that sends this traffic performance.
For simple declaration process, parameter in the present embodiment is dwindled with reference to real system and is amplified, suppose that every N slot forms a frame (Frame), here N value is 10, the cycle of frame is 10ms, in system, as shown in Figure 4, node 5 has taken time slot 6, one hop node schematic diagrames as shown in Figure 5 to node 1 ~ 9 Time Slot Occupancy situation.Suppose that node 5 wants transmission delay 2ms, sends the high-priority service of frequency 200Hz when time slot 8.
A concrete implementation process is as follows:
Other nodes in current network, the FI receiving does corresponding processing, comprises and judges whether to make a concession the own current time interval resource taking and to upgrade time slot state table etc. for the node of high-priority service.
Take node 2 as example, correctly receiving node 5 after the FI of time slot 0 transmission, judging the resource taking is not the time interval resource oneself having taken, and upgrades the time slot state table of oneself, and instructs node 5 takies the { information of time slot 0, time slot 5 and time slot 6}.The processing procedure of node 1,3,4 is similar.
Take node 6 as example, correctly receiving node 5 after the FI of time slot 0 transmission, what discovery node 5 was seized is the time slot of oneself, abandons time slot 5, continues to wait for free timeslot access.
When node 5, monitoring after feedback stage hears the time slot that has indicated own STI and selection in the FI of other nodes, just thinking and oneself access successfully, continuation transmission FI and message above the time slot of seizing at oneself.Otherwise node 5 thinks that own time slot reservation is failed, restarts multi-slot reservation process.
Embodiment 2: system is without high priority access slot, and vehicle need to send low time delay, send the high high-priority service of frequency, and the former time slot that takies meets the embodiment that sends this traffic performance.
The parameter of the system in the present embodiment is with reference to embodiment 1, and in system, as shown in Figure 6, node 5 has taken time slot 5, one hop node schematic diagrames as shown in Figure 5 to node 1 ~ 9 Time Slot Occupancy situation.Suppose that node 5 wants transmission delay 2ms, sends the high-priority service of frequency 200Hz when time slot 9.
A concrete implementation process is as follows:
Other nodes in current network, the FI receiving does corresponding processing, comprises and judges whether to make a concession the own current time interval resource taking and to upgrade time slot state table etc. for the node of high-priority service.
Take node 2 as example, correctly receiving node 5 after the FI of time slot 0 transmission, judging the resource taking is not the time interval resource oneself having taken, and upgrades the time slot state table of oneself, and instructs node 5 takies the { information of time slot 0 and time slot 5}.The processing procedure of node 1,3,4,6 is similar.
When node 5, monitoring after feedback stage hears the time slot that has indicated own STI and selection in the FI of other nodes, just thinking and own time slot reservation success above the time slot of seizing at oneself, continue transmission FI and message.Otherwise node 5 thinks that own time slot reservation is failed, restarts multi-slot reservation process.
Embodiment 3: system has high priority access slot, and vehicle need to send low time delay, send the embodiment of the high-priority service that frequency is high.
The parameter of the system in the present embodiment, with reference to embodiment 1, has 1 high-priority service access slot every 4 common time slots in system, and in system, as shown in Figure 7, node 5 has taken time slot 6, one hop node schematic diagrames as shown in Figure 5 to node 1 ~ 9 Time Slot Occupancy situation.Suppose that node 5 wants transmission delay 2ms, sends the high-priority service of frequency 200Hz when time slot 8.
A concrete implementation process is as follows:
In order to strengthen node 5 time slot reservation reliabilities, node 5 takies message at high-priority service access slot TS0 and the application of TS5 sending time slots, broadcast its current common time interval resource taking, application takies in message and needs the S TI that comprises oneself and the time slot oneself taking, as { time slot 9, time slot 4 and time slot 6}.
Other nodes in current network, receive after the Time Slot Occupancy message of high-priority service access slot, do corresponding processing, comprise and judge whether to make a concession the own current time interval resource taking and to upgrade time slot state table etc. for the node of the high-priority service of low time delay, high frequency.
Take node 2 as example, after correctly receiving the Time Slot Occupancy message of high-priority service access slot TS0, judging the resource taking is not the time interval resource of controlling oneself and taking, and upgrades the time slot state table of oneself, shows that node 5 takies the { information of time slot 9, time slot 4 and time slot 6}.The processing procedure of node 1,3,4 is similar.
Take node 6 as example, at the time slot TS0 or the TS5 that correctly receive high-priority service access slot, take after message, what discovery node 5 was seized is the time slot of oneself, abandons time slot 9, continues to wait for free timeslot access.
When node 5 is being monitored after feedback stage hears the STI and the time slot of selection that has indicated oneself in the FI of other nodes, just think that own time slot reservation is successful, can no longer send application and take message, but in order to strengthen the reliability of reception, also can repeat to send application and take message, and above the time slot of seizing at oneself, continue to send FI and message.Otherwise node 5 thinks that own time slot reservation is failed, restarts multi-slot reservation process.
