3, RRC_INACTIVE state (the inactive state of RRC, inactive state) and light RRC connection (RRC
The light connection of connection status) it introduces
A kind of new mobility status RRC_INACTIVE (the inactive state of RRC, inactive state) is introduced in NR system.
When UE in this state when, although RAN node releases the RRC connection of the UE, but still retain UE NG2 and
The connection of NG3 interface.
The side UE and RAN node store UE AS context (terminal access layer contextual information), so as to quickly extensive
Arrive connected state again or be maintained at inactive state and send/receive data；
UE is transparent to core net in the state, i.e., core net still believes that UE is constantly in connected state, therefore downlink signaling
Or data will reach RAN node, RAN needs to page UE at this time, introduces the band of position a RAN level RNA (RAN
Notification Area).UE is under inactive state, and RAN node gNB in all cells under the region RNA by sending out
Notification message notification is sent to search UE.If the UE of inactive state out of the corresponding region RNA, needs to carry out
RNA updates, so that RAN network side node can find the UE.
In LTE system, UE is likely to be at the light RRC connection of RRC connection status.With inactive state
Similar, at this time although RAN node releases the RRC connection of the UE, but the side UE and RAN node store UE AS context.UE
Side storage UE AS context include before RRC configuration, safe context, PDCP state (including ROHC state), source take
The corresponding cell mark of the corresponding C-RNTI of the UE and source service main plot and physical-layer cell identifier under business main plot.Core
Heart net still believes that UE is constantly in connected state.When there is the arrival of DL data, LTE base station (is sought by initiating the side RAN paging
Exhale message) paging UE.When LTE base station configuration UE enters the light RRC connection of RRC connection status, it can match simultaneously
Set the region RAN paging.If subsequent UE removes the region corresponding RAN paging, need to carry out the corresponding side RAN
Paging domain updates.
Under eLTE network, if the side UE and the side RAN store UE AS context simultaneously, while core net is still believed that
UE is constantly in connected state, what state at this time is, does not discuss also, it may be possible to inactive state or RRC connection status
Light RRC connection or other states.
With the development of wireless communication system, terminal type and type of service diversification, saving power for terminal save Internet resources
With meet the needs of various businesses type and deposit.In order to guarantee saving power for terminal and rapid data transmission simultaneously, in the New RAT of 5G
(NR) a kind of SOT state of termination " inactive state " is introduced in system, keeps core net connection in the terminal of inactive state, but
Without the routine operation (such as switching, uplink timing update, radio link monitoring) for connected state of eating dishes without rice or wine, does not distribute and be directly used in
The terminal iidentification (such as C-RNTI) of air interface transmission, therefore cannot directly carry out air-interface scheduling transmission.In inactive (inactive)
Under state, terminal needs to monitor paging message, to guarantee that the calling from network side can be received.When the terminal of inactive state
When being moved to other systems from NR system (such as LTE/eLTE system), terminal can not continue to keep inactive state, and terminal side
Concrete behavior what is at present there is no providing, therefore will lead to terminal and can not work on.

In the specific implementation process, after UE completes mapping process, in UE when sending UL, source identification will can be mapped
Information carries in UL, and with informing network side, the current UE AS context is to map from which RAT.
In the following, technical solution of the present invention will be described in detail in conjunction with specific embodiments:
The terminal of the RRC_INACTIVE state (i.e. inactive state) of one: NR network of embodiment enters from NR network
After eLTE network, UE AS context mapping is carried out at once.
Referring to FIG. 5, UE in NR network, is configured to inactive state, it is stored with the corresponding UE AS of NR network
context.The subsequent UE is moved to eLTE from NR, it is assumed that and the eLTE eNB and NRgNB belong to the same paging domain, including
RAN paging domain, UE do not need to carry out paging domain update after entering eLTE eNB, do not need triggering UL and send.NR network
Inactive state, correspond to eLTE system, it is assumed that (can also be with for the light RRC connection of RRC connection status
It is other titles, such as unactivated state, UE and RAN eats dishes without rice or wine to disconnect in side under which, but UE and RAN side gusset is respectively stored with
The AS context of UE).
Step 0: in NR network, UE enters inactive state, obtains UE under distributed inactive state and marks
Know, while being stored with the corresponding UE AS context of NR network.The NR network UE AS context includes at least following several portions

For parameter needed for subsequent calculating shortMAC-I, exist including at least the UE before entering inactive state
The corresponding physical-layer cell identifier of radio network temporary identifier, main serving cell, main serving cell under main serving cell is corresponding
Cell Global Identity above three parameter；
After step 1:UE is moved to eLTE network from NR, status becomes RRC connection status by inactive state
light RRC connection。
UE is by UE identity map under inactive state under the light RRC connection of RRC connection status
resume id.Current resume id is 40bit, if the UE mark under inactive state is still 40bit, UE can be straight
Connect the UE mark under the inactive state stored before setting resume id to；If the UE under inactive state
Mark (such as 48bit) is longer than resume id, then the UE mark that can be set resume id under inactive state
The preceding 40bit or rear 40bit known；If the UE under inactive state identify (such as 32bit) it is shorter than resume id,
The UE mark that resume id can be so set under inactive state lacks high bit directly with 0 supplement, Huo Zhecong
Highest order starts to be supplemented with the UE marker under inactive state, and insufficient low bit then with 0 supplement.
Meanwhile UE carries out correlation map according to the UE AS context under the NR network stored, obtains eLTE network
Under UE AS context, specific rules include at least following sections:
1) using the default RRC configuration under eLTE network, SRB (Signaling Radio Bearer) configuration including default,

Optionally, in the UE AS context under eLTE network, a mark can also be increased, for identifying current be somebody's turn to do
UE AS context is incoming to reflect from NR network；
After the completion of UE AS context mapping, the UE AS context under the NR network that UE is stored can be deleted, or
Person continues to retain；Corresponding, UE mark can also delete under inactive state, or continue to retain；
Step 2: with the movement of UE, UE is again from eLTE Network Mobility to NR network, at this time:
The state of UE becomes inactive state；
If step 1, UE remains the UE AS context under the mark of UE under inactive state and NR network,
Then without carrying out relevant mapping；
If the UE mark under the current not inactive state of UE and the UE AS context under NR network,
It then needs accordingly to be mapped the information stored under eLTE network, it is similar with step 1, specifically:
Resume id under the light RRC connection of RRC connection status is mapped as under inactive state
UE mark；If UE is identified under resume id length < inactive state, the UE under inactive state is identified into setting
For resume id, high bit is lacked with 0 polishing, or supplemented since highest bit with resume id, it is insufficient
Low bit then with 0 supplement；If UE is identified under resume id length > inactive state (such as UE under inactive state
It is identified as 32bit), then the preceding 32bit of resume id or rear 32bit are used for UE under inactive state and identified；
UE AS context under the light RRC connection of RRC connection status is mapped as under NR network
UE AS context specifically includes at least following sections: being configured using the default RRC under NR network；It continues to use original
Security configuration and PDCP state；The mark stored stored before continuing to use, for calculating shortMAC-I；In addition, due to
In step 1, in the UE AS context under the light RRC connection of RRC connection status, including a mark, it uses
Incoming to reflect from NR network in identifying the current UE AS context, UE is returned to NR network at this time, then mapped
New UE AS context do not need to increase this mark (because the side UE with network side interacting in eLTE network,
The UE AS context of network side is still stored in NR network).
After the completion of UE AS context mapping, the UE AS context under the eLTE network that UE is stored can be deleted,
Or continue to retain；Corresponding, resume id can also be deleted, or continue to retain；
Meanwhile in step 1 and 2, if due to other reasons (for example being transferred to connected state), the current RAT that is stored
UE AS context and UE mark need to delete, then if UE can store multiple RAT UE AS context and UE mark,
UE AS context and the UE mark of other RAT is also required to accordingly delete.
