Description
Technical field
The present invention relates to the communications field, the transmission method and device of data are carried in particular to a kind of NAS.
Background technology
Machinery compartment (Machine to Machine, hereinafter referred to as M2M) communication is that the 5th third-generation mobile communication technology (5G) is current
One important topic of research, is also an important applied field of future wireless system.In M2M problems, for low cost,
The termination property such as low-power consumption, Hypomobility, poor throughput, it is proposed that arrowband Internet of Things (NarowBand-Internet of Things,
Hereinafter referred to as NB-IoT) the sub- problem of research, that is, in 200khz frequency band it is NB-IoT low cost terminals (User
Equipment, hereinafter referred to as UE) provide poor throughput wireless communication services.
In order to reduce signaling consumption, the power consumption of NB-IoT terminals is reduced, correlation technique introduces two kinds of small data transmission modes：
1st, chain of command optimal way (hereinafter CP modes)：The number that will not be set up between terminal and base station between terminal and network
According to carrying (Date Resource Bearer, referred to as DRB), AS safe contexts will not be also set up, data are packaged into NAS
PDU is attached in control plane signaling and transmitted.The effect that this mode saves signaling is obvious, but the long data packet once transmitted
Degree is limited, for being sent than larger packet, it is necessary to be divided into multiple parcels, in the case where covering is poor, easily brings and loses
Bag problem, causes recipient to be difficult to receive complete packet.
2nd, user plane optimal way (hereinafter UP modes)：Terminal and network set up complete connection, and number is transmitted using DRB
According to after data transfer is finished, in terminal and network side by hanging up flow preservation carrying information context, Access Layer (Access
Stratum, referred to as AS) safe context etc., when subsequently sending data again, both sides protect before being recovered by recovering flow
The context deposited, is continuing with DRB carryings to transmit data.This mode and existing procedure difference is little, to the length of packet
Degree is not substantially limited, but the effect for saving signaling is limited.
For above two mode, or institute it is in need by user face data be packaged into Non-Access Stratum (Non Access Stratum,
Referred to as NAS) protocol Data Unit (Protocol data unit, referred to as PDU) and be attached to RRC connections foundation control
, all there is problems with the prioritization scheme transmitted in plane signaling processed：
1st, in correlation technique, there was only Attach, Tracking Area for triggering the NAS flows that AS layers of RRC connections are set up
Update, Detach, Service Request, but its corresponding NAS signaling can not accommodate user data, with Service Request
Exemplified by message, its message structure is as shown in table 1：
(3GPP 24.301) Table of table 1 8.2.25.1:SERVICE REQUEST message content
2nd, in correlation technique, following two groups of NAS signalings separately provide data capsule, available for application layer data is carried, i.e.,
Downlink NAS Transport/uplink NAS Transport and Downlink generic NAS transport/Uplink
generic NAS transport.But Downlink NAS Transport/uplink NAS Transport signalings, existing protocol is clear and definite
It is only used for carrying short message (SMS) data.In addition, the above-mentioned two groups of NAS signalings of protocol requirement can only be in terminal and network side
It could be used in EMM-CONNECTED patterns, and only terminal and network side is completed after RRC connections foundation, its evolution
Grouping domain system mobile management (Evolved Packet System Mobility Management, referred to as EMM) entity
EMM-CONNECTED patterns can just be entered, so in existing protocol, thering is application layer data to need when terminal is in Idle state
When sending, above-mentioned two groups of NAS signalings can not be used.
3rd, in CP schemes, in correlation technique, interface can only set up a signaling bear between terminal and base station in the air
(Signal Resource Bearer) SRB1 signaling bears, will not set up DRB Deta bearers.The NAS that terminal or network are sent
Signaling either a common NAS signaling, such as Tracking Area Update Requet/Tracking Area Update
Accept, still encapsulates the NAS signaling of application layer data, is required for being carried in SRB1 signalings, it is clear that encapsulating should
Larger with the NAS signaling bag length of layer data, transport overhead is big, and the transmission to common NAS signaling can be impacted.Related skill
Have in art and mention to common NAS signaling and encapsulate the various schemes that the NAS signaling of data is transmitted by different priorities,
But when current terminal and network side can't effectively distinguish this two classes NAS signaling, particularly terminal and network side in Idle state.
For in correlation technique, in the control for needing that user face data is packaged into NAS PDU and RRC connections foundation is attached to
The problem of in plane signaling in the presence of transmission plan, at present it is not yet found that the solution of effect.
