For ease of describing and being better understood from the technical scheme provide in the embodiment of the present invention, below to being related to The definition of feature such as " cell-of-origin ", " source base station ", " cooperation district " arrived, " same mbsfn region ", The explanations such as embodiment.In explanation, need illustrated in order to understand with example when, will with v2x business, Illustrate as a example ue, v2x information.
In embodiment, a mbsfn region includes a first community and at least one second community. Wherein, for cell, single antenna or multiple antennas are adopted to realize the wireless signal to specific region in base station During covering, these specific regions are referred to as cell, and this concept of cell is also often referred to this particular coverage area User terminal in domain provides the logic entity comprising base station software and hardware subsystem of service.
First community is that its administrative each ue can be in v2x business, by v2x information reporting to the first base The cell stood, then, the first community in embodiment is referred to as " cell-of-origin ", and first base station is referred to as " source base station ".
Wherein, a mbsfn region only one of which first community, and, a mbsfn region only has One corresponding Time And Frequency resource, when in actual scene, a mbsfn region can correspond to many parts Between and frequency resource, but, in the same time, mbsfn region corresponding Time And Frequency resource is only One.
Several second communities are then had, these second communities can be belonged in one mbsfn region Other base stations, it is of course also possible to belong to first base station, the second community in embodiment is referred to as " association Same cell ".
" source " refers to produce the source of data, and the data that this source produces is the number of this mbsfn region transmission According to " working in coordination with " namely the data assisting the generation of this source of transmission.Data in embodiment namely " v2x information ".
Thus, in force, the base station of v2x information distribution, is belonging to first community for data cell-of-origin The each second community ownership in mbsfn region each second base station, meanwhile, with first community as data source The mbsfn region of cell, refers to that the corresponding data that sends in this mbsfn region is produced by first community.
So, v2x information by each second community under each base station corresponding with described mbsfn region Time And Frequency resource on send, particularly as follows:
V2x information will belong to each second community with first community for the mbsfn region of data cell-of-origin Each the with first community for the mbsfn region of data cell-of-origin is respectively belonged under each second base station of ownership In two cells, with the described mbsfn region corresponding time with first community for data cell-of-origin with frequency Send in rate resource.
If there is second community in the cell belonging in first base station, then first in first base station is little In area and each second community, v2x letter is sent on Time And Frequency resource corresponding with mbsfn region Breath, particularly as follows:
Belong to mbsfn region with first community for data cell-of-origin in the first community of first base station with respectively Second community in, with the described mbsfn region corresponding time with first community for data cell-of-origin With transmission v2x information in frequency resource.
In scheme, on base station and adjacent base station, in identical Time And Frequency resource with Mbms mode issues v2x information to each ue, and such purpose is to ensure that in same mbsfn region Interior ue can be simultaneously received the v2x information reporting from the ue of same cell.And v2x The purpose of business is to enable the ue in relevant range timely to get this v2x information, for example it is ensured that This v2x information can be received with reporting the ue of the v2x information all ue in the range of 300 meters, Will be necessary so that these ue are in same mbsfn region with the ue reporting v2x information, should The v2x information that ue reports issues as the data source in this mbsfn region.In other words, by controlling The cell composition in mbsfn region, you can ensure v2x information issues scope.Process due to data Journey is carried out according to mbsfn region, and mbsfn region is made up of cell, and this also just anticipates Taste and is determined that the composition cell in same mbsfn region is the key component implemented, therefore below to cell with And how each cell forms mbsfn region and illustrate, to more fully understand that the embodiment of the present invention provides Technical scheme enforcement.
Fig. 8 constitutes schematic diagram for mbsfn region, and Fig. 9 is that in High-speed Circumstance, mbsfn region composition is shown It is intended to, Figure 10 is cell and the interregional relation schematic diagram of mbsfn, Figure 11 is little under highway scene Area and the interregional relation schematic diagram of mbsfn, as shown in the figure:
Enhanced realize in v2x communication plan based on embms, next mbsfn region of normal conditions Constitute mbsfn region 1 as shown in Figure 8 by adjacent multiple cells to be made up of cell 1-cell 7, each There is a data cell-of-origin, this cell is responsible for producing each little in this mbsfn region in mbsfn region The data content that area is sent in mbsfn mode, and data content is distributed to its in this mbsfn region His cell (cell in same mbsfn region may belong to different enb) is such as permissible in fig. 8 Select cell 1 as the data cell-of-origin in this mbsfn region.In different scenes, a mbsfn The cell number comprising in region can be configured according to actual environment, such as in highway environment Mbsfn region can be configured along highway, and the mbsfn region shown in Fig. 9 is by along public affairs at a high speed 3 cells of road distribution are constituted, and cell 1 is as the data cell-of-origin in this mbsfn region.
In order to realize seamless v2x communication, need overlapped as cell-of-origin establishment using each cell Different mbsfn regions.Figure 10, in 11, it is to represent different mbsfn with numbered circle Region, the numbering in each cell middle position circle is using this cell as data cell-of-origin The numbering in mbsfn region, if had in multiple cell during the circle of same numbering then it represents that these are little Area belongs to the same mbsfn region with this number-mark.
As shown in Figure 10, when each the mbsfn region in system is by a cell and about 6 When cell is constituted, each cell has a mbsfn region centered on oneself, each is little Area will (such as cell 1-cell 7, other cells, because being in edge, be schemed by 7 mbsfn region overlay In do not draw, so not by 7 mbsfn region overlay).As shown in figure 11, when public at a high speed In the scene of road, each mbsfn region is made up of a cell and 2 cells about, each cell When all there is a mbsfn region centered on oneself, each cell will be by 3 mbsfn Region overlay (such as cell 1, cell 2, cell 3, cell 5, other cell4, cell6 because being in edge, In figure does not draw, so not by 3 mbsfn region overlay).
In lte system, the data in different mbsfn regions takies different subframes and sends, therefore not Do not exist with the data is activation in mbsfn region and interfere.
In the enforcement of step 402, it will be related to the transmission of information between first base station and the second base station, That is: distribute information between each the of each second community ownership belonging to same mbsfn region with first community Two base stations.Below the enforcement to the information distribution under this situation first is illustrated.
During described above, it is to illustrate from the enforcement of first base station and the second base station side respectively, but This is not meant to that the two must coordinate enforcement, in fact, when first base station is performed separately with the second base station, It also each solves the problems, such as first base station and the second base station side, when simply the two is used in combination, can obtain more Good technique effect.It should be noted that, for same base station, due in different mbsfn regions Solve the problems, such as different, therefore its may simultaneously need to implementing the scheme of first base station and the second base station, the One base station, the appellation of the second base station merely to preferably illustrating the scheme providing in the embodiment of the present invention, and It is not intended that one of scheme can only be implemented in a base station.

3rd, the enforcement in handoff procedure
In Fig. 4,5 method for sending information one, two implementation processes, terminal unit occurs the feelings of switching Condition, illustrates to the situation of switching below.
Figure 19 be lte network architecture schematic diagram, as illustrated, lte grid side entity by Mme/s-gw, enb form.Interface between enb and enb is x2 interface, mme/s-gw and enb Between interface be s1 interface.
In lte network, when ue moves to another enb from an enb, in order that occurring Business do not interrupt, need to switch over.If there is x2 between enb to connect, then x2 can be passed through Interface is completing handoff procedure；If there is no x2 interface between enb, can be completed by s1 interface.
Figure 20 passes through the non-competing Stochastic accessing switching flow schematic diagram of x2 interface for lte system, such as schemes Shown, the measurement report being reported based on ue in source enb and rrm (RRM) information are judged After ue needs to switch over, mainly comprised the steps: by the handoff procedure of x2 interface
Step 2001, source enb send handover request (handover request) message to target enb；
Carry ue in handover request information and switch over information necessary to preparation to target enb, such as: Context (context) information in the enb of source for the ue, target cell id etc.；
Step 2002, target enb return handover request ack (Handover Request Acknowledge) to source enb Message；
If the resource that switching ue is used goes through in target enb, then Target cell will be this ue Configure corresponding resource, and send handover request ack message to source enb.Handover request ack message package contains Ue to target enb switch when required parameter information, such as: may comprise target enb system information, Ue preamble (lead code) information when target enb carries out Stochastic accessing etc.；
Step 2003, source enb send rrc connection reconfigurationg to ue, and (rrc is even Connect configuration) message；
Source enb, after the handover request ack message receiving the transmission of target enb, sends switching life to ue Make information, instruction ue switches over to target enb.In the switching command that source enb sends to ue Hold and be included in the handover request ack message that target enb sends to source enb；
Step 2004, ue send random access preamble (random access guiding to target enb Sequence)；
Step 2005, target enb return rar, and (random access response, Stochastic accessing rings Should)；
After receiving switching command, the synchronization of ue execution and target enb.If dispensing in switching command Special rach preamble (rach targeting sequencing；Rach:random access channel, RACH), then access Target cell using uncontested random access procedure, special without dispensing Rach preamble, then access Target cell using based on competition random access procedure；
Step 2006, ue send rrc connection reconfigurationg complete to target enb (rrc connects configuration to be completed) message.
After ue is successfully accessed Target cell, ue sends handoff completion message, indicates ue to target enb Switching flow complete.
Figure 21 passes through the non-competing Stochastic accessing switching flow schematic diagram of s1 interface for lte system, as schemed institute Show, different from the switching flow being carried out by x2 interface be to need by mme, by s1 interface Handoff procedure mainly comprises the steps:
Step 2101, source enb send handover required (switching demand) message to mme；
Step 2102, mme send handover request message to target enb；
Step 2103, target enb return handover request ack message to mme；
Step 2104, mme return handover command (switching command) message to source enb；
Step 2105, source enb send rrc connection reconfigurationg message to ue；
Step 2106, ue send random access preamble to target enb；
Step 2107, target enb return rar；
Step 2108, ue send rrc connection reconfigurationg complete to target enb Message；
Step 2109, target enb send handover notify (switching notice) message to mme.
Related content due to being not involved with information in switching be can be seen that by above-mentioned two switching flow, The ue that target enb can not be directed to specific information transmit-receive does corresponding process.Taking v2x business as a example, The relevant information whether ue receives and dispatches v2x business is not comprised, target enb is not in current hand off signaling Special handling can be done for the ue carrying out v2x transmitting-receiving, and this may result in the ongoing v2x of ue Business is interrupted, and causes traffic safety hidden danger.Certainly, other business there is also same problem.

If ue switching is ratified by objective network side gusset, the execution of objective network side gusset is corresponding to be operated, And relevant configuration information is notified source network side gusset.
By the program, the ue to support v2x business for objective network side gusset during switching can be enable Carry out special handling, ensure seriality in ue handoff procedure for the v2x business.
4th, the enforcement that in transmitting procedure, information integrity is protected.
In Fig. 4,5 method for sending information one, two implementation processes, the safety to information it is also proposed Require, below the performance of Information Security is illustrated.
First the asymmetric cryptosystem being related in implementing is illustrated.
Asymmetric-key encryption system, is also called public-key cryptosystem, double-key cipher system.It refers to right The key being used when information encryption and deciphering is different, that is, have two keys, and one is can be disclosed, Another is privately owned, and this two keys partner key pair, respectively public-key cryptography and private cipher key. If be encrypted using one of data key, only could be deciphered with another one key.By The key being used when encryption is with deciphering is different, and this encryption system is referred to as asymmetric-key encryption system. In public key algorithm, it is encrypted with disclosed key, the process being decrypted with private cipher key, claim For ciphering process.And be encrypted with private cipher key, the process being decrypted with public-key cryptography referred to as certification (and Claim integrity protection) process.The confidentiality of asymmetric cryptographic algorithm relatively good it is not necessary between encryption and decryption user Carry out key exchange.
The essence of integrity protection is that transmitting-receiving two-end will calculate check code, pass through in plain text as |input paramete The concordance of the check code that transmitting-receiving two-end calculates, to prove the concordance of two ends |input paramete, is one in plain text Cause.Figure 24 is integrity protection process schematic, as illustrated, in complete protection procedure, making a start Carry out the message of integrity protection itself by the use of tegrity protection key and other specification and needing as complete The input of whole property protection algorism, generate an integrity protection check code mac-i, make a start by message itself with Mac-i sends jointly to receiving terminal；Receiving end utilizes tegrity protection key and corresponding parameter and message originally Body, as the input of protection algorithm integrallty, generates an integrity protection check code xmac-i, with reception To mac-i be compared, if consistent then it is assumed that the message of the message that is subject to and transmission is consistent, Do not distorted by third party.It should be noted that when using symmetric key mechanisms, make a start key and receipts End key is identical, when using asymmetric key mechanisms, makes a start key and receiving end key is different, Make a start and adopt private key, receiving end adopts public key.
In order to realize Fig. 4, the enhanced communication based on embms described in 5, in the embodiment of the present invention Also proposed the safe handling scheme of corresponding data, for solving network side node after collecting information, Information Security when terminal unit under being covered to present networks side gusset using embms mode is sent is asked Topic, the program specifically can be used on the network side nodes such as base station, repeater.
To described each second base station distribution information, and to specified terminal unit send information when, enter one Step includes:
Described information is carried out integrity protection with private key, described private key is corresponding with described mbsfn region Private key.
When, network side node carries out integrity guarantor by collect through private key taking v2x business, ue as a example The related packet of road safety after shield is sent to ue.
In being embodied as, what network side node was collected carries out the road safety phase after integrity protection through private key The packet closing is divided into two classes: a class is the road safety that the ue in coverage is reported by network side node Related packet carries out the packet after integrity protection using the private key that network side node oneself associates；Separately One class is the packet that network side node obtains from other network side nodes, and other network side nodes can be The existing network side gusset such as enb, henb, relay or the network side node subsequently newly increasing, These packets adopt other network side nodes by other network side nodes before reaching network side node Corresponding private key has carried out integrity protection.Wherein, network side node sends packet and can adopt mbsfn Mode can also be using p2m (point to multipoint, point-to-multipoint) broadcast or multicast mode.
The packet of the road safety correlation that the ue in coverage is reported by network side node adopts network side Packet after the private key of node oneself association carries out integrity protection is sent to other related around networks Side gusset.This is because the data cell-of-origin in each mbsfn region needs in this mbsfn region Other cells provide identical data, to ensure that all cells in a mbsfn region can be in phase Send identical data on same running time-frequency resource, receive diversity gain so that receiving ue and obtaining.Network side Node, it needs to be determined that the cell of this network side node association, and determines each cell as data cell-of-origin Other cells in mbsfn region, the packet of the road safety correlation that ue under each cell is reported is adopted Carried out after integrity protection with each cell corresponding integrity protection private key, be sent to each cell as data source The corresponding network side node of other cells in the mbsfn region of cell.
In enforcement, it is to carry out the letter of integrity protection with private key corresponding with described mbsfn region in information During breath, include by with this mbsfn region corresponding rule treatments information:
Determine public key corresponding with described mbsfn region；
Carry out carrying out integrity verification to the information after integrity protection using described public key.
Equally, when, ue receives the road safety of network side transmission taking v2x business, ue as a example After related packet, according to the corresponding safety in mbsfn region of the network side node transmission receiving Public key carries out integrity verification to the packet in each mbsfn region.When different mbsfn regions adopts During different public key, because a cell may belong to multiple mbsfn regions, ue may receive To the corresponding packet in multiple mbsfn regions, therefore, ue is being carried out completely to the packet receiving Property checking before need first to determine packet corresponding mbsfn region, then adopt this mbsfn region Public key carries out integrity verification to packet.
In enforcement, public key can be the public key that base station sends, and/or, it is stored in the public key in terminal unit, And/or, the public key that (as by rsu (road side unit, roadside unit)) obtains by other means.
Accordingly, in enforcement, base station side may further include:
Send the public key that the information after integrity protection is carried out with integrity verification, described public key to terminal unit It is public key corresponding with described mbsfn region.
In enforcement, public key can be from mme's and/or mce.
When, ue is after receiving the integrity protection that network side node sends taking v2x business, ue as a example The related packet of road safety, need to obtain in advance the packet related to the road safety receiving and carry out The public key of integrity verification.Ue knows that the public key of integrity verification can adopt two ways:
Mode 1: the mbsfn region corresponding safety public key that oneself is associated by network side node is sent to ue.
Here network side node can be the existing network side gusset such as enb, henb, relay it is also possible to It is the other types of network side node (as rsu) subsequently newly increasing.The mbsfn of network side node association Region includes the mbsfn region of each cell association under network side node.Network side node can associate one In individual or multiple mbsfn regions, such as Figure 10, cell 1-cell 7 is associated with 7 mbsfn regions.This In safety public key for ue, integrity is carried out to the road safety information receiving from network side node and tests Card.
Safety public key can be produced it is also possible to be produced by higher network side node by network side node itself Raw, such as (multi-cell/multicast coordination entity, multiple cell is many for enb, mme, mce Broadcast coordination entity), hss (home subscriber server, home subscriber server), bm-sc (broadcast multicast service center, broadcast multicast service center) etc..Network side node will be from The mbsfn region corresponding safety public key of oneself association is sent to ue and can adopt broadcast, multicast, list Broadcast mode.When sending using broadcast mode, system broadcasts (as carried in the sib setting) can be adopted, Can also be using mbms broadcast (as in mcch, (multicast control channel, multicast controls Channel) in carry or as specific business in mtch (multicast traffic channel, multicast industry Business channel) in carry)；When being sent using mode of unicast, can be in securitymodecommand (peace Syntype order) carry in signaling and (pass through it is also possible to carry in other rrc signalings or nas signaling The public key that this mode obtains can be tested to the legitimacy of base station)；
During switching, target enb corresponding public key can be sent to ue by switching command it is also possible to After the completion of switching, ue is sent to by nas message by target enb, can also be that ue is being switched to target Pass through behind base station to receive the system information acquisition that target enb sends.Consider after handover in enforcement, mesh Cell under mark enb may be associated with new mbsfn region, therefore, in being embodied as, in switching When the corresponding public key in mbsfn region of target enb cell association can be informed ue.
In enforcement, corresponding for each mbsfn region safety public key directly can also be existed the sim of ue (subscribers identity module, Subscriber Identity Module) or usim (universal subscribers Identity module, universal subscriber identity module) in card.
Below the enb enforcement that safety is processed during information is sent to ue is illustrated with example Journey.
Embodiment d1:
Described in the present embodiment, the road safety related data packets that ue under each cell is reported by enb1 It is sent to ue, and the road safety related data packets that ue under each cell is reported after carrying out integrity protection It is sent to the adjacent enb of correlation after carrying out integrity protection.
If comprising two cells cell 1 and cell 2 under enb1, little as data source using cell 1 and cell 2 The mbsfn region in area is respectively mbsfn region 2 and mbsfn region 3, mbsfn region 2 He The subframe that mbsfn region 3 takies is respectively subframe 7 and subframe 8 in each radio frames；Wrap under enb2 Containing cell cell3, the cell 3 of the cell 1 and enb2 of enb1 is the adjacent cell in geographical position, enb2 Cell 3 belong in the cell 1 of enb1 for the mbsfn region 2 of data cell-of-origin, the cell of enb2 3 need in the upper transmission of the corresponding subframe in mbsfn region 2 (subframes 7 in each radio frames) and enb1 Cell 1 in identical data in the corresponding subframe in mbsfn region 2, mbsfn region 2 is corresponding Subframe on send data enb2 is transmitted to by enb1.Figure 25 is the information transfer carrying out safe handling Implementation environment schematic diagram, as illustrated, having ue1 and ue2 under enb1 shown in Figure 25, two ue All under cell 1 covering, under enb2, there is ue3, under cell3 covering, enb1 turns ue3 to enb2 Send out the road safety data sending in mbsfn region 2 and pass through x2 interface.Idiographic flow is as follows:
1st, enb1 collects the road safety packet that ue1 and ue2 reports；In being embodied as, to ue1, Road safety packet that ue2 reports collect can be periodic harvest (as every 30ms) or Setting time point is collected, such as corresponding for the mbsfn region of data cell-of-origin with cell each under enb1 At setting time before mbsfn subframe, the road safety number that can also at any time ue be reported as required It is collected according to bag；
2nd, the packet collected is carried out integrity protection using private key by enb1.For example in this example, right The data that ue1 and ue2 reports adopts the corresponding private in mbsfn region using cell1 as data cell-of-origin Key carries out integrity protection；
3rd, enb1 is by each cell under enb1 for the packet after integrity protection, with each cell as number Send according to the data form setting is pressed on the mbsfn region corresponding mbsfn subframe of cell-of-origin.Specifically For, then enb 1 needs the packet reporting ue in cell 1 after carrying out complete preservation through private key The subframe that mbsfn region 2 takies sends according to the data form setting.Meanwhile, enb1 will be complete Packet after whole property protection is transmitted to each cell as other in the mbsfn region of data cell-of-origin The corresponding network side node of cell, for example in this example, the cell3 under enb2 belongs to the cell under enb1 1 is the mbsfn region 2 of data cell-of-origin, and therefore, enb1 needs to have carried out cell 1 using private key Data forwarding after whole property protection is to enb2.
