Embodiment
Inventor notices during invention：
The flow for the transition between states supported at present is：
The state from IDLE to CONNECTED, terminal needs to be accessed or process of reconstruction., can from CONNECTED states
To enter IDLE state by release process.
But it is as follows some other special state to be also present：
CN (Core Network, core net) PSM (Power Save Mode, power save mode), corresponding to RRC's
IDLE state.In this condition, network saves UE context, and by distributing to a UE resume (recovery)
Mark, to carry out context recovery.
In the discussion of ongoing light connection (light connection), in light connection situation
Under, the user is in connection status in terms of core net, but it is connectionless to eat dishes without rice or wine.In this case, terminal uses cell reselection
Moving property of mode, access net side retain terminal context information.Base station reaches initiation according to downlink data and sought
Exhale, terminal carries out data transmit-receive after entering connection status.It is up if data are sent, terminal can initiate resume processes and enter
The recovery of line link, into connected state after carry out data transmission.
The SOT state of termination newly introduced：Sluggish connected state (inactive state), allow in this condition as follows
Behavior：
- core net sees that the UE is in connection status；
- mobility is that UE is performed, and in the pre-configured RAN tracing areas of network side, is performed by cell reselection, and
It is not that handoff procedure is carried out；
The unique subscriber identification in the pre-configured RAN tracing areas of network side is assigned in-terminal.
Under Inactive states, network side is that effective RAN marks, the mark are used in terminal distribution certain area
Identification terminal under inactive states, it can be used for network side and search when terminal or terminal actively initiate multi-upstream access with mark work
Enter connected state for identification.Inactive UE ID are properly termed as, are referred to as resume UE ID.The mark is different
In globally unique IMSI (International Mobile Subscriber Identity, international mobile subscriber identification code)
Or connected state terminal iidentification C-RNTI, the identification length fall between (such as inactive UE ID length is 40bit,
C-RNTI length is 16bit), only in the certain area comprising multiple cells or multiple eNB effectively, if it exceeds the region,
Terminal needs to update inactive UE ID.
In the existing SOT state of termination, except RRC connected states are assigned with terminal air interface transmission unique mark C-RNTI can be direct
Data transmit-receive is carried out, when other states there are data to need transmission, terminal will be introduced into RRC connected states, establish RRC connections, obtain
The terminal air interface transmission unique mark in data transfer is taken, such as C-RNTI, follow-up data transfer could be carried out.
However, with the development of wireless communication system, terminal type and type of service variation, saving power for terminal, net is saved
Network resource and meet the needs of miscellaneous service type and deposit.Such as it is above-mentioned, in order to ensure that saving power for terminal and rapid data pass simultaneously
It is defeated, a kind of SOT state of termination inactive states are introduced, terminal keeps core net connection under this state, but without connected state of eating dishes without rice or wine
Routine operation (such as switching, up timing renewal, radio link monitoring), do not distribute the terminal mark for being directly used in air interface transmission
Know (such as C-RNTI), therefore be introduced into RRC connected states as above-mentioned, established RRC connections, obtain mark, progress subsequent data transmission
Flow then can not directly carry out air-interface scheduling transmission.
It can be seen that above-mentioned be introduced into RRC connected states, establish RRC connections, obtain mark, carry out the flow of subsequent data transmission
Process is unfavorable for having quick transmission during data arrival, and if only burst small data packets need to send, such as typical MTC
(Machine Type Communication, machine type communication) business, after terminal has sent out a small data packets into connected state
In order to which power saving enters idle or inactive states again, this transition between states can cause signaling consumption, if terminal quantity is huge
When (such as mMTC, massive MTC scenes), this signaling consumption is almost unacceptable.
Based on this, will solve how to carry out rapid data under inactive states in the embodiment of the present invention or signaling passes
It is defeated.The embodiment of the present invention is illustrated below in conjunction with the accompanying drawings.
It in declarative procedure, will be illustrated respectively from the implementation of UE and base station side, then will also provide the two and coordinate in fact
The implementation for the scheme that the example applied is provided with more fully understanding in the embodiment of the present invention.Such explanation mode is not meant to two
Person must coordinate implementation or must individually implement, in fact, when UE and base station are performed separately, its also each solve UE sides,
The problem of base station side, and during the two combined use, superior technique effect can be obtained.
Two kinds of embodiments are additionally provided in embodiments of the present invention, and mode one, mode two are individually identified as in application, its
In, the embodiment of mode one will illustrate in embodiment 1,2, and the embodiment of mode two will be in embodiment
Illustrated in 3.Specifically：
In UE after connected states are transformed into inactive states, received in base station the UE transmission small data or
After signaling, signaling or data will be sent to core net according to UE contextual informations.
Namely：In UE after connected states are transformed into inactive states, when base station receive terminal upstream data or
During person's signaling, the target BS is further according to information (the anchor base station mark obtained or the UE contextual informations of preservation or UE are reported
Knowledge or inactive UE ID), the data or signaling are sent to core net.
Concrete mode one is：Target BS judge oneself whether be UE anchor base station, anchor base station refers to and core net
Node establishes the base station for the special connection for having the UE, if it is not, then the core net node into UE contexts initiates RAN anchor points
Renewal process, the message can carry the upstream data to be transmitted simultaneously or play drinking games；Or target BS updates in RAN anchor points
Process has performed and then has sent the upstream data to be transmitted or signaling to core net.
Further, if target BS is not UE anchor base stations, the target BS also needs to notify UE anchor base stations
Renewal, new anchor base station can be sent and identified to UE, or inactive UE ID, the mark can be redistributed to UE
Identified comprising anchor base station, this information is used for the anchor base station information that subsequent target base station judges UE, after performing above-mentioned function.Mesh
Mark the UE contextual informations that base station renewal preserves.
Concrete mode two is：Target BS judge oneself whether be UE anchor base station, if it is not, then according to obtain or
The core net node address specified in the UE contextual informations of preservation, directly send data to core net.If target BS is
UE contexts, target BS are obtained by context fetch processes (target BS asks acquisition context to anchor base station)
Need to indicate in this process, anchor base station still needs to retain the UE contexts；
Further, target BS can be based on timer, delete the UE contextual informations.
In the description of the embodiment of the present invention, anchor base station/cell of the UE refers to：Come for the UE of unactivated state
Say, it leaves serving BS/cell when connected state enters inactive state, or is stored with UE whole access network related contexts

- it is stored with the related contextual information of UE wholes access network；
- it is that UE is assigned with inactive ID, the anchor nodes can be found using the ID, further find the UE's
Contextual information.
For the UE in Inactive states, due to UE, movement need not lead in the certain area of network configuration
Know network side, therefore work as the coverage that UE removes its anchor base station, and be in the coverage of another base station, now UE
If necessary to send data or signaling, it will be attached and communicate with the base station, this base station is referred to as UE in inactive
