Fig. 2 shows showing for the unicast multicast hybrid network 200 in mobile broadband network in accordance with an embodiment of the present disclosure
Meaning Organization Chart.In fig. 2, eMBMS blocks node refers to that the full node with eMBMS multicast capabilities (is referred to as block multicast section
Point), they are trusted nodes, are configurable to the seed node of common full node and SPV nodes.Each block multicast node
All there is corresponding multicast (also referred to as multicast) region.Different multicast areas can have different block multicast nodes.These
Block multicast node may belong to different Mobile Network Operator, can also take different eMBMS channels.
As illustrated in FIG. 2, block chain network 200 includes multicast area 210 and 220.Exist in each multicast area
Corresponding block multicast node, i.e. eMBMS blocks node 211 and 221.Multicast area 210 include common full node 212,
214th, 215 and SPV nodes 213.Include common full node 222,223,225 and SPV nodes 224 in multicast area 220.

Logic association, physically can be by connecting including the various modes such as wired, wireless between each node in block chain network 200
Connect.The disclosure is not limited in this regard.
Node in block chain network 200 can both have the ability for receiving eMBMS multicasts, can also be without reception
The ability of eMBMS multicasts, but they have the ability interacted by unicast with other nodes.As an example, such as multicast area
Full node 212, SPV nodes 213 and full node 215 (shown in phantom) in domain 210 possess the ability for receiving eMBMS multicasts,
And full node 214 does not possess the ability for receiving eMBMS multicasts.Similarly, in multicast area 220 full node 222, full node
223 and full node 225 (shown in phantom) possess the ability for receiving eMBMS multicasts, and SPV nodes 224 do not possess reception eMBMS
The ability of multicast.
In accordance with an embodiment of the present disclosure, when block chain node is mutually shaken hands by unicast, tell whether other side oneself has
Send and receive the ability of multicast.It is moreover, each that there is the node for digging ore deposit or generation new block ability to be once created that new block,
New district block message is preferentially sent to the eMBMS blocks node of interconnection and without the section for receiving eMBMS multicast capabilities by it
Point.
In such block chain network 200, after eMBMS blocks node obtains new district block message and is verified, pass through
Block information is sent to the node with multicast reception ability in its multicast area by multicast.In addition, for without reception
The node of multicast capability, it can obtain block information using traditional mode of unicast.Thus, block chain network 200 can be propped up
SPV nodes are held, full node can also be supported, and the node with multicast reception ability can be supported, can also support only have
There is the node of unicast capabilities.
Can be via the delivery of unicast block information between eMBMS block nodes between different multicast areas 210 and 220
, in this way, can be by by eMBMS multicasts or block information is transmitted to corresponding eMBMS blocks node by other nodes
Newest block chain is synchronized to network intra block chain node, efficiently solves traditional P2P networks occupancy Internet resources excessive and easy
Cause the shortcoming of network storm, be particularly suitable for the scene that mobile broadband network and Internet of Things are combined.On the other hand, block chain link
Point is fast by the speed of the synchronous block chain of eMBMS multicasts, and the intermediate node of process is few, can reduce the probability of soft bifurcated, reduction
The energy consumption of the block chain proved using workload (POW, prove of work).
EMBMS blocks node 211 can encapsulate to realize to the message group in multicast area by the message of multicast block
Broadcast.Fig. 3 shows the method 300 that can be performed by multicast node in accordance with an embodiment of the present disclosure.Method 300 for example can be
Performed at eMBMS blocks node 211.
310, at the block multicast node of block chain network, new district block message is obtained.In one embodiment, this is new
Block information can eMBMS blocks node 211 received from the block node in block chain network, or by the eMBMS
What block node 211 was produced.Then 320, block multicast node is verified to new district block message.
330, effective in response to the new district block message of empirical tests, block multicast node is based on multiple in block chain network
The node type and new district block message of block node, generate different types of block multicast message.
In accordance with an embodiment of the present disclosure, each block is used into similar eMBMS multicasts as an independent file
The scheme of file carrys out multicast block.In order to improve the multicast efficiency of block information and effectively utilize bandwidth resources, multicast node life
Into different types of block multicast message.
Fig. 4 shows the message encapsulation 400 of traditional eMBMS Multicast Files.As illustrated, file can be divided many
Small data block is placed on the file transmission (FLUTE in the one-way transmission of multicast message：File Delivery over
Unidirectional Transport) send in inclusion (i.e. payload).Field 401 indicates unicast ip address, example
If message is by the address for the BM-SC being sent to.Instruction user datagram protocol (the UDP of field 402 and 405：User Datagram
Protocol) header.Field 403 is SYNC heads, indicates SYNC protocol informations.SYNC agreements are used for the reality of broadcasting packet
Time synchronized between body (such as each base station).Field 404 indicates the Multicast IP Address corresponding with multicast area.And be divided
Data block in field 406 by respectively carrying send.
Because the SPV nodes in block chain only need to reception area block header, and block head is typically smaller.For example, than
The block head of special coin is 80 bytes, and it can be directly placed into a UDP bag.Thus, embodiment of the disclosure introduces block
Header (BLOCK packet header) field, it includes block data type (BLOCK type) and block height
(BLOCK height).Content in the block data type mark message is block header information or block Transaction Information,
Block is highly used for the height for depositing current block.In one example, block heading can be 9 bytes, wherein block counts
Can be 1 byte according to type, 8 bytes are used for the height for depositing current block in addition.

In protocol stack 400 outside each fields of 401-405, in addition to block heading field 501 and block head 502.Block heading word
Section 501 is made up of two subfields of foregoing type and height.Block head 502 includes the block of the block in block chain
Header information, as previously described.
In figure 6, the multicast message of Second Type encapsulates 600 in addition to each fields of 401-405 in message protocol stack 400,
Also include block heading field 601, FLUTE heads 602 and FLUTE payload field 603.Similarly, block heading
Field 601 is made up of two subfields of foregoing type and height.Block is carried in FLUTE payload field 603 to hand over
Easy data.In one example, when the value of type field is 0x01, represent that data below are block heads.Work as type
When field is 0x02, represent that data below are block Transaction Informations.
After block multicast node is generated according to as above process and encapsulates different types of block multicast message, 340,
MBMS nodes into mobile broadband network send different types of block multicast message, with cause via mobile broadband network to
Multiple block node broadcasts block multicast messages.
In one embodiment, block chain multicast node 211 generates different types of block multicast message, is sent to movement
MBMS nodes such as BM-SC 120 in network.Via BM-SC120, different types of block multicast message is broadcast.
Thus, there is the node for receiving multicast capability can receive these block multicast messages in multicast area 210, and message is carried out
Processing, so as to obtain block information.
According to one embodiment of the disclosure, for SPV nodes, it is only necessary to which it is 0x01's to receive and parse through BLOCK type
Message, and ignore the message that BLOCK type are 0x02, to save energy consumption.And for full node, two kinds of message is all needed
Receive.For arbitrary node, if the block in message highly finds the block by receiving otherwise,
The message can also be ignored.
What it is due to MBMS multicasts transmission is the message based on UDP bags, namely does not guarantee that authentic communication is transmitted, thus many
Broadcast receiving end signal it is bad when, transmission is likely to occur the situation of packet loss.Embodiment of the disclosure is also provided for two kinds
The different solutions of different BLOCK type message packet loss.
For the block multicast message (i.e. block transaction message) of Second Type, block transaction data is logical as a file
Cross Transport FLUTE protocol encapsulation and send, forward error correction coding (FEC, Forward Error Correction) technology can be used
To be encoded to block transaction data.Specifically, according to the packet loss of block chain network, specific FEC can be used to encode
Algorithm (for example, Rator10), is that the block transaction data of such as new block generates a certain proportion of repair data.
According to one embodiment of the disclosure, block transaction data is divided into multiple transmission source blocks；To multiple transmission source blocks
Forward error correction coding is carried out, encoded multiple transmission source blocks are encapsulated as multiple multicast messages based on Transport FLUTE protocol afterwards.
If sent for example, block transaction data can be divided into N number of message, then the data through forward error correction coding can pass through M
Message is sent.At block chain node, if the sum of the message received is K, as long as meeting K>N+L(0<L<M), FEC is solved
Code algorithm can just restore original block transaction data.Thus, by file forward error correction coding, realize and block is handed over
Effective and reliable transmission of easy data.
For the block multicast message (i.e. block head message) of the first kind, forward error correction coding skill can be equally used
Art tackles packet loss.In another embodiment, the mode that repetition is sent can be used to solve block head message dropping
Problem.For example, block multicast node is before the transaction data of a block is sent, pre-determined number is always first sent (for example, 2
It is secondary) block head message.During block transaction data is sent, interspersed repetition can also be configured repeatedly as desired and is sent
Block head message.In this way, realize to the effective of block header information and reliable transmission.
If in addition, a node were not received by block head message or complete block transaction data, Ke Yitong
The mode for crossing unicast is obtained from adjacent node.
Fig. 7 and Fig. 8 respectively illustrate the method that can be performed by full node and SPV in accordance with an embodiment of the present disclosure.Can
It is included in 710 in the method 700 performed by for example full node 212 of full node, at the full node of block chain in multicast area, connects
Receive the block multicast message of the block multicast node in multicast area.The block multicast message includes the first kind as above
And Second Type, the block multicast message of the first kind at least includes the block head of block information, and the area of Second Type
Block multicast message at least includes the block transaction data of block information.
Then 720, the block multicast message of the full node parsing first kind and Second Type, to obtain block information.
Specifically, for example the full node 212 with multicast reception ability can by recognizing the block header of block multicast message,
Determine the type of block multicast message.If the first kind, then the block head in block multicast message is extracted；If block
Multicast message is Second Type, then extracts the block transaction data in block multicast message.
In one embodiment, the FEC algorithms that full node 212 is also interacted based on communicating pair are to received multiple
The multicast message of Second Type carries out fec decoder, so as to obtain block transaction data.In another embodiment, full node 212 is gone back
It is determined that whether obtained block information is complete.If the block information arrived is imperfect, sent a request for adjacent node
Complete block information.
In accordance with an embodiment of the present disclosure, if full node 212 generates a new block, it is to block multicast node 211
The new district block message is sent with the node (such as full node 214) without reception multicast capability in multicast area 210, to cause
New block is broadcast to by multicast area 210 by block multicast node 211.At the same time, the block multicast in multicast area 220
The new block can further be broadcast to the block chain node in multicast area 220 by node 221.
Fig. 8 shows the method that can be performed by SPV nodes (such as SPV nodes 213) in accordance with an embodiment of the present disclosure
800.810, at the SPV nodes in multicast area, the block multicast of the block multicast node in multicast area is received
Message, block multicast message includes the first kind and Second Type, and the block multicast message of the first kind, which at least includes block, to be believed
The block head of breath, and the block multicast message of Second Type at least includes the block transaction data of block information.
Then 820, the block multicast message of the first kind is parsed, to obtain block information.Specifically, for example with many
Block multicast message can be determined by recognizing the block header of block multicast message by broadcasting the SPV nodes 213 of receiving ability
Type.If the first kind, then the block head in block multicast message is extracted；If block multicast message is Equations of The Second Kind
Type, then ignore or abandon the message.In this way, not only contribute to save bandwidth resources, be also beneficial to save the work(of SPV nodes
Consumption.
In certain embodiments, adjacent node of the SPV nodes 213 into its multicast area notifies multicast capability information, should
Multicast capability information indicates oneself whether there is the ability of multicast that sends, receives the ability of multicast or send and receive multicast
Ability.
By embodiment of the disclosure described above, there is provided pass through unicast and eMBMS under mobile broadband network
Multicast is the scheme of block chain mixed networking.Program network throughput is big, and real-time is good, it is adaptable to which trading frequency is high, transaction
The high scene of requirement of real-time.In addition, the change to original block chain P2P networks is smaller, relative ease is compared in realization.
