Specific embodiment
In order to which the purpose, technological means and advantage of the application is more clearly understood, the application is done below in conjunction with attached drawing It is further described.
In order to reduce the signaling of paging domain and the foundation of reduction business, it is currently suggested a kind of sluggish state (Inacive) or gently the UE connection type of (Light Connection) is connected.
Inactive state or light connection refer to that wireless access network does not request core when the connection of wireless access network release UE Connection of the net release about UE, for example, between base station and core network control surface (S1 interface control plane or NG2 interface) about UE's Connection, the connection of (S1 interface user plane or NG3 interface) about UE between base station and core network user face.
In 5G, when UE is in inactive state, wireless access network still keeps the context of UE, (keeps UE context Wireless access network node is properly termed as old wireless access network node), core net can consider that UE is still within connected state.When having When upstream data, UE can transmit data by two ways：Mode one directly transmits upstream data under inactive state, than Such as sent by the resource of unauthorized (grant free)；Mode two：It returns to and carries out data transmission after connected state again.Never live Jump state returns to connected state and needs certain signaling overheads.Employing mode one can save signaling in the case where data volume very little.
To the data transmission of mode one, there is also a series of problems.It is analyzed one by one below：
Problem 1：The condition that data transmission is carried out under inactive state or connected state is not known.
The data transfer performance of inactive state may not be able to meet some business, the QoS grade of some data, such as URLLC, Voice, IMS, NAS layers of data.
UE can only just know that the cache information of upstream data, the cache information without knowing downlink data.Only rely only on The state that unilateral data buffer storage information carrys out determination data transmission is inaccurate.It is connect when from UE from new wireless access network node Fashionable, new wireless access network node needs the UE that makes an immediate response after the context that old wireless access network node obtains UE.Meanwhile New wireless access network node can distribute data forwarding addresses, receive UE data from old wireless access network node.But New wireless access network node should just determine the state of UE data transmission when responding UE.The data such as new wireless access network node Forwarding is completed to determine the state of UE data transmission with regard to too late again.
Problem 2：It is not clear whether or how to carry out data transmission state update.
In data transfer procedure, the state of data transmission is changed always.In data transfer procedure,
It is no longer small data if 1) data buffer storage is continuously increased.At this point, continuing to carry out data transmission under inactive state It is inefficient, and resource is no longer saved, it may no longer meet the qos requirement of data.
2) on the other hand, if data buffer storage is constantly reduced, data volume has been reduced to small data, continue under connected state into Row data transmission may waste dedicated channel resource.
State if necessary to carry out data transmission updates, it is unclear that how to support the update of the state of data transmission.
Problem 3：In general, the data transmission under connected state needs to configure dedicated channel for UE.It is inactive to UE or light It is connected to, UE can be released in the dedicated channel resource of wireless side, but the contexts such as session, carrying of UE are still saved. It, may waste of resource if restoring all dedicated channels when the subsequent data transfer needs produced about UE.Because Possible not all session or all carryings require data transmission.

Hereinafter with reference to Fig. 5, to the side about data transfer state control of third exemplary embodiment according to the present invention Method is specifically described.Fig. 5 is the method about data transfer state control according to the third exemplary embodiment of the present invention Flow diagram.As shown in figure 5, method 500 is related to the determination that data transmission configures under particular state comprising following steps：
Step 501, third node determines whether to meet the predetermined condition of data transmission under particular state.
Optionally, third node can be at least one of following according to knowing, it is determined whether meets data under particular state and passes The predetermined condition sent：Context (as described in step 301), the shape of the data transfer information (as described in step 301) of UE, UE State change report (Status Change is reported described in step 602 as will hereinafter be described).
In some embodiments, particular state is inactive state.Optionally, the predetermined condition of inactive state data transmission It can include but is not limited at least one：
- UE can carry out data transmission under inactive mode.For example UE can, support, be allowed to or be suitble to do not living Data transmission is carried out under jump mode.
