Embodiment
For the object, technical solution and advantage of the application are more clearly understood, develop simultaneously embodiment referring to the drawings, right
The application is described in further detail.
In order to meet the UE of small data quantity low cost (such as IOT (Internet of thing, Internet of Things), CE
(coverage enhancement, coverage enhancement), LC (low cost, low cost), MTC (Machine Type
Communication, machine type communication) equipment) communication requirement, it is proposed that a kind of CIOT (Cellular IOT, honeycomb thing
Networking) communication service.CIOT (Cellular Internet of Thing honeycombs Internet of Things) is a kind of data transmission optimization
Method.CIOT data can carry on a control plane (such as Non-Access Stratum protocols data cell (NAS PDU)) transmission or
Person is carried in user plane (such as UE carryings) transmission.
The CIOT of Deta bearer on a control plane is referred to as chain of command CIOT optimizations.Chain of command CIOT optimizations need not be wireless
UE carryings are established in access network node, it is not required that wireless security context is established in wireless access network, is encrypted in core net
Middle execution.Optimized by chain of command CIOT, it is convenient to omit the signaling consumption needed for UE carryings is established, so as to shorten UE access networks
Or the time delay of UE transceiving datas.
CIOT of the Deta bearer in user plane is referred to as user plane CIOT optimizations.Optimized by user plane CIOT, UE is no longer
When enlivening, UE contexts are suspended rather than are deleted.Until there is data transfer needs UE contexts be resumed rather than by
It is newly-built, so as to reduce the signaling consumption that UE connections are established or UE carryings are established, so as to shorten UE access networks or UE transceiving datas
Time delay.
To CIOT communication services, it can be used for broadband radio access network (such as WB EUTRAN, LTE) network, can also use
Wireless access network (such as NB IOT) in arrowband.Core net node or wireless access network node can support CIOT and non-simultaneously
CIOT only supports CIOT.Support CIOT core net node or support CIOT wireless access network node to support to control simultaneously
CIOT is only supported in face CIOT optimizations (abbreviation chain of command CIOT) processed and user plane CIOT optimizations (referred to as user plane CIOT)
Chain of command only supports CIOT user planes.The business for supporting low time delay requirement is one of the 5th third generation mobile communication network important
Technical characteristic.Therefore, the method for this data transmission optimizations of CIOT can also be applied among the mobile communications network in future,
IOT equipment is not limited to, is also not limited to existing radio network technique.
Prior art there is problems：

Mobile IOT UE are also the important component in IOT UE.Such as wearable equipment, Intelligent bracelet, drive recorder
Deng.In order to strengthen and improve mobility and service continuity, it can require that NB IOT networks and IOT UE support switching.
But to chain of command CIOT UE, it there is problems
- existing switching flow does not support the data forwarding of chain of command.
- existing switching flow requires the context of transmission user plane UE carryings (ERAB), but chain of command CIOT business only has
The carrying of chain of command, carried without the UE of user plane.
- existing switching flow requires transmission UE security information (such as new key) relevant information, but chain of command CIOT industry
Business does not have safe context not require to encrypt in wireless access network.
- because switching requires the signal quality of UE measurements peripheral cell, certain energy loss can be caused.
Problem 2：For core net, the re-transmission of the signaling of chain of command is supported.In general, only do not meet with a response
Control plane signaling just need to retransmit, such as MME have sent ATTACH ACCEPT after receive ATTACH COMMPLETE, ATTACH
COMMPLETE just turns into ATTACH ACCEPT confirmation.But for chain of command CIOT, only data pass through control
Face is transmitted, not tangible ACK information.At present, wireless access network be not notified that yet core network control surface data send into
Work(still sends failure.
So core net retransmission mechanism cannot guarantee that the continuity of data transmission.
Problem 3, it is not differentiate between core network control surface signaling (such as NAS signaling) and chain of command in wireless access net side
CIOP data (data over NAS).Core network control surface signaling can turn due to there is core net retransmission mechanism without data
Hair.Chain of command CIOP data need data forwarding.The differentiation of both is also unintelligible.
