Description
Technical field
The present invention relates to machine type communication (MTC, Machine Type Communication) technology,
Espespecially a kind of methods, devices and systems for realizing data transfer.
Background technology
With the fast development and the increasingly increase of people's communication requirement of wireless communication technology, the 5G epoch will
Arrive.A 5G important function is exactly MTC, and MTC possesses large-scale potential application foreground, made
It wins a large amount of Mobile Network Operator, equipment manufacturers, the extensive concern of research institution.MTC is main
Application field includes intelligent grid, intelligent transportation, smart home, long-range measurement, wireless sensor network
Deng.It is the important component of emerging Internet of Things.
The business that MTC user equipmenies (UE, User Equipment) are supported is various.It is most of
MTC UE require low cost and low-power consumption, such as big quantity sensor of environmental monitoring or agricultural etc..
The business that MTC UE are supported is usually low rate, it is also possible to the situation of transmission big data in need.
The business that MTC UE are supported is not general high to delay requirement, it is possible that emergency needs quick pass
Defeated situation.
For example, the business of fire alarm equipment has following several：
Periodically report keep-alive information, it is low to delay requirement, data volume it is small to tens bits (Byte) or
Person is smaller；
Fire alarm information is reported, higher to delay requirement, data volume may be small to tens Byte, but also may be used
Number million (M) can be arrived greatly, and this is due to that may need to report video information in some cases；
Software version update, to delay requirement than relatively low, data volume may have several M than larger.
As can be seen here, the business that MTC UE are supported is various, including periodic traffic is reported, exception
The multiple business such as reporting events, networking command are issued, software version update.Different business is to network requirement
Service quality (QoS, Quality of Service) it is also different.In addition, MTC UE may
Transmit in the data of high-speed, such as portable use, intelligent glasses may need to transmit real-time video number
According to；Intelligent watch may need to make a phone call, and this business needs very high QoS.
MTC UE quantity is also likely to be magnanimity, and substantial amounts of MTC UE access may give Netowrk tape
Carry out substantial amounts of signaling consumption.In order to effectively reduce MTC UE cost, also for the letter for saving MME
Expense is made, third generation partner program (3GPP, 3rd Generation Partnership Project) is proposed
The method of realizing data transfer, this method is generally comprised：
MTC UE send attachment (Attach) request to MME；Wherein, Attach requests include
The data transfer mode that MTC UE are supported；A kind of transmission side data in MME selection Attach requests
Formula, preserves the information related to the data transfer mode selected, and send Attach responses to MTC UE；
Wherein, Attach responses include the data transfer mode of selection；MTC UE are preserved to be responded with Attach
The related information of the data transfer mode of middle selection；When MTC UE or MME need transmission data,
Data are transmitted using the data transfer mode of selection.
Wherein, data transfer mode includes chain of command mode or user plane mode.
Wherein, chain of command mode refers to packet being packaged into Non-Access Stratum (NAS, Non-Access
Stratum) protocol Data Unit (PDU, Protocol Data Unit) is included in control plane signaling and passed
It is defeated.The advantage of chain of command mode is to save signaling, network overhead and MTC UE power consumption；Inferior position is peace
Full performance is slightly worse, and this is due to not set up Data Radio Bearer (DRB, Data in chain of command mode
Radio Bearer), correspondingly, MME and UE are without Access Layer (AS, Access Stratum)
Safe context, therefore, it is impossible to carry out AS layers of encryption to packet；Be not suitable for the larger number of transfer ratio
According to, this is due to NAS PDU limited length, for than larger packet, it is necessary to be divided into multiple
Small packet is transmitted, and MTC UE network signal is typically bad, easily produces showing for packet loss
As, cause recipient to be difficult to receive complete packet, and chain of command mode is passed using control plane signaling
Transmission of data, excessive parcel will bring the transmission of excessive control plane signaling, take excessive resource；It is low
Priority data services take too high scheduling resource, and this is due to that the periodicity that MTC UE are sent is reported
The priority ratio of data is relatively low, but is due to that the data are sent in the signaling of layer 3 of eating dishes without rice or wine is attached to, so that
Obtain and conventional radio resource control (RRC, Radio Resource Control) signaling is the same
Dispatching priority processing, so that the dispatching priority of real RRC signaling can be tied up, may cause higher
Access failure of eating dishes without rice or wine；When simultaneously MTC UE support that data are using chain of command optimal way and use data
Radio bearer (DRB, Data Radio Bearer) transmit when, due to Signaling Radio Bearer (SRB,
Signaling Radio Bearers) dispatching priority sum it is higher than DRB, therefore, these low priorities
Data can always obtain the dispatching priority processing higher than DRB, may cause what is transmitted using DRB
The scheduling of high-priority service cannot be ensured.
Wherein, user plane mode refers to transmit data, after data transfer is finished, MTC UE using DRB
Preserved respectively with MME above and below carrying information context, Access Layer (AS, Access Stratum) safety
Text etc., when subsequently sending data again, MTC UE and MME is recovered by hang-up-activation process
The use of DRB carryings.The advantage of user plane mode is that encryption performance is relatively good, and this is due to MTC UE
AS safe contexts are saved with MME, MTC UE and MME can carry out AS layers to data and add
It is close；The data or big data high to rate requirement can be transmitted.Inferior position is that signaling optimization effect is poor, this
It is due to need first to reply carrying information context, then transmits data；Carrying information context maintenance expense
Than larger, there is the different risk of the carrying information context preserved between MTC UE and MME, this
It is due to that the general use times of MTC UE are long, and MME is unanimously in change；MTC UE
Need to migrate carrying information context and AS safe contexts etc. during change access cell, expense is larger.
In the existing method for realizing data transfer, when it is determined that just no longer change after a kind of data transfer mode,
And the requirement for the data that MTC UE needs are transmitted is different, therefore, the flexibility of data transfer is relatively low.
