Description
Technical field
The present invention relates to the monitorings of one of wireless communication technology field more particularly to 4G and 5G communication system Radio Link
Method and user equipment.
Background technique
Prior art Long Time Evolution system (LTE, Long Term Evolution) is mainly made of three equipment：With
Family equipment (UE, User Equipment), core net (CN, Core Network) and base station (eNB, Evolved Node B),
Wherein, the mobile management entity in core net (MME, Mobility Management Entity) is mainly responsible for the biography of signaling
Defeated, gateway (SGW, Serving GetWay) is mainly responsible for the transmission of data.The interface of UE and eNB is Uu, eNB and core
The interface of net is S1, as shown in Figure 1, being the architecture diagram of LTE.
And the agreement framework of UE, eNB and MME, as shown in Figure 2.For UE, protocol layer RRC (Radio Resource
Control, wireless heterogeneous networks), PDCP (Packet Data Convergence Protocol, packet data convergence association
View), RLC (Radio Link Control, radio link layer control), MAC (Medium Access Control, media intervention
Control) and PHY (Physical Layer, physical layer) belong to AS (Access Stratum, access layer) layer, and AS layers of high level
For NAS (Non Access Stratum, non-intervention layer) layer.
It is provided according to present agreement, UE will be communicated with eNB, first have to access the eNB, that is, initiate random access mistake
Journey.As shown in figure 3, random access procedure includes four steps, it is respectively：
Step 1：UE by system information or RRC signaling know for random access available leader sequence code and
Send leader sequence time-frequency location, then, in available resource, random selection leader sequence and send leader sequence when
Frequency position, and it is sent to eNB；
Step 2：The time-frequency location that eNB is used by random access leader sequence infers the RA-RNTI that UE may be used,
And leader sequence is decoded with RA-RNTI, after leader sequence is successfully decoded out in eNB, give UE to reply random access response, in response
Carry the information such as uplink authorization；
Step 3：UE sends RRC in the resource of uplink authorization and establishes request message；
Step 4：ENB parses upstream data in the resource of uplink authorization, confirms UE, solves conflict, and send competition and determine
Knowledge assess a bid for tender to UE.
Then, UE enters connected state, then send/receive data.
But this process at least needs four steps, is delayed longer, in order to simplify step, proposes in inactive state,
UE sends/data are received, as shown in figure 4, including the following steps：
Step 1：UE sends leader sequence to eNB；
Step 2：After leader sequence is successfully decoded out in eNB, random access response is replied to UE, uplink is carried in response and awards
The information such as power；
Step 3：UE sends RRC information in the resource of uplink authorization and carries upstream data, alternatively, line number in UE transmission
According to and the information such as mark for carrying UE；
Step 4：ENB parses upstream data in the resource of uplink authorization, confirms UE, solves conflict, and send competition and determine
Knowledge assess a bid for tender to UE.
As it can be seen that this method of the method for transmitting data under inactive state than transmitting data under activated state, time delay
It is smaller, it is more flexible.
Under activated state, for the continuity for guaranteeing transmission, UE needs to monitor the state of Radio Link, in case of wireless
Link failure will timely restore.Similar with activated state, wireless quality can also occur when inactive state transmits data and be deteriorated by UE
The problems such as.But it is different from activated state, inactive state does not need to restore Radio Link in time, but needs to pass data again simultaneously
It is defeated by network, this will lead to data transmission fails.
So how to monitor the state of inactive state and the Radio Link under light connected state, data normal transmission is ensured,

In the present embodiment, the solicitation message can be RRC Connection Reestablishment
Request, RRC Connection Resume Request or new information.
After base station receives solicitation message, it can be determined that going out the UE is that Radio Link Failure, root has occurred under default state
According to the UE identification information carried in message, the base station for saving UE context is found, the contextual information of UE is then obtained, is built for UE
Vertical RRC connection.If can not find the contextual information of UE, base station will establish RRC connection again for UE, and update the configuration of UE.
Mode two：Initiate cell reselection.Specifically, when initiating cell reselection, in order to avoid choosing current area again, also
The native region priority of current area is turned down.
If UE has selected a cell again, and the cell can support the data transmission under default state, then UE is in the cell
Under continue to execute under default state data transmission.
In conclusion the method for the embodiment of the present invention, user equipment be in disconnected with the interface of base station and base station with
It, can be by the re-transmission situation of RLC PDU, to the Radio Link of user equipment when core net keeps the state of the connection of the UE
State is detected, and in the Radio Link Failure for detecting user equipment, is carried out Radio Link reparation, is both conveniently adapted to UE
In the mobility of inactive state, and the time delay of data transmission can be reduced, very good solution in the prior art, can not to inactive
Radio Link under state is monitored, and then influences the problem of data export.

Whether the number that number continuously reaches given threshold reaches the third threshold value of setting, specifically includes：
When UE sends data packet, HARQ reaches maximum retransmission, and MAC layer can indicate that HARQ reaches maximum re-transmission to RRC
Number, if the number that rrc layer continuously receives MAC layer instruction reaches the third threshold value of setting, then it is assumed that Radio Link Failure or
Person current area is not suitable for providing data transport service.
In the embodiment of the present invention, third threshold value can be allocated to UE by base station broadcast or by RRC information, such as：Pass through
System information, RRC connection reconfiguration, RRCConnectionRelease or new information are allocated to
UE。
Step S702 carries out Radio Link reparation when detecting the Radio Link Failure of UE.
In the embodiment of the present invention, the mode for carrying out Radio Link reparation includes but is not limited to be：
