Embodiment 2
Figure 12 is that four step RACH process schematics, Figure 13 are the signal of two step RACH processes in the related technology in the related technology
Figure illustrates that UE sends the process of upstream data in inactive state by taking the four steps RACH process as an example：
The first step：UE sends message 1, including：
UE randomly chooses a preamble from the random access channel resource that cell configures, and in random access channel
Upper transmission.
Second step：Access network elements receive the message 1 of UE transmission, respond message 2；
Wherein, the Message 2 is also known as RAR message (Random Access Response), carries in RAR message
For the echo message of the UE preamble sent, the uplink authorization (UL grant) of the resource including sending message 3,
And information (the timing advance of interim a RNTI (temp C-RNTI) and uplink timing adjustment
command)。
Third step：UE sends message 3；
If UE receives the RAR echo message for its premable transmitted by message 1, according to timing
Adjustment information adjustment sends the timing slip of uplink signal, and message 3 is sent in the resource of the uplink authorization.
The content of the message 3 includes：
The mark of UE；Showing as can be with the unique identification UE in the RNA of access net in UE Context ID or other
Mark or it is other can be with the mark of the unique identification UE in a cell.
And the upstream data of UE.
Optionally, the content of the message 3 further includes：The authentication information of UE, such as short MAC-I.
Optionally, the content of the message 3 further includes：UE initiates the reason of transmitting uplink data information
(cause)。
Optionally, the content of the message 3 further includes：Information (the buffer of UE up data buffer
Status report, BSR).
4th step：Access network elements respond message 4；
Here, for the message 3 received, network side passes through the scrambled PDCCH signaling scheduling hair of temp C-RNTI
The channel resource of message 4 is sent, UE obtains message 4 by the temp C-RNTI that detection receives in message 2
Scheduling information to receiving messag 4.
Include contention resolution MAC CE in the Message 4, includes to be used for UE in the MAC CE
The mark of contention resolved, the UE for receiving message 4 check that the UE contention resolved identifies whether the contention resolved mark for oneself
Know, if it is, this RACH process of UE successfully terminates, the otherwise this time contention resolved failure of RACH process.
In the related art, after message 4 is also by a RRC information is carried to update the AS configuration of UE, indicate UE
The authentication information of continuous RRC state and offer access network elements.
The process shown in Figure 13 is similar with process shown in Figure 12, is sent to access net net in the first step UE of Figure 13
Information in the message 1 of member is that message 1 is superimposed with information in message3 in Figure 12；It is connect in the second step of Figure 13
Network element be sent to the information in the message 2 of UE be in Figure 12 in message 4 information it is similar, herein no longer in detail
Description.
From the description above it is found that if the service network element where UE initiates the cell that upstream data is sent is different from UE's
When anchor network element, as described in Example 1, services and need a series of interaction, ability between network element and the anchor network element of UE
Determine the subsequent RRC state of UE and behavior.On the other hand, UE needs to confirm that service network element is not the access net net of a personation
Member, it is therefore desirable to access network elements be authenticated, i.e. offer access network elements authentication information, and generate access network elements certification
The code key of information is also required to be transmitted to service network element from anchor network element.
And in view of the interaction between service network element and anchor network element has delay, such as in the related art, the two
Between unidirectional communication delay may be up to 100 milliseconds (ms), then multiple delay maximum can arrive several hundred milliseconds back and forth.
If message 4 could be sent by terminating interactive process between service network element and anchor network element, UE need this most
It keeps monitoring down control channel in big several hundred milliseconds of the time, this consumes the battery of UE in vain.
More disadvantageously, UE can not during this period of time judge whether its RACH process succeeds or contention resolved loses
It loses.Therefore, if UE contention resolved during current RACH has failed, (UE transmission is not successfully decoded in access net
Message 3), UE can not continue to initiate new RACH process, to increase the delay that the UE sends upstream data.
For above-mentioned problem, present embodiments provide following method (in conjunction with shown in Figure 11 and Figure 14, be described below with
For four step RACH processes)：
The access network elements for receiving message 3 send the MAC CE (UE of contention resolved by message 4
Contention Resolution MAC CE), and carrying UE monitors the time letter of down control channel in message 4
Breath.
Receive the UE of message 4, if it is determined that the contention resolved that message 4 is carried is identified as the competition solution of the UE
Award of bid is known, then the UE is according to the above-mentioned temporal information for monitoring down control channel, to monitor down control channel.
It may include as under type that the above-mentioned UE indicated in message 4, which monitors the temporal information of down control channel,
It is a kind of：
One time migration information；That is UE is supervised since the time that the time for receiving the information adds the time migration
Listen down control channel；
One time migration information and a time span information；I.e.：UE is from the time of the information is received plus described
The time of time migration monitors down control channel within the time of the time span.It is default in time migration information
When, the time offset value is 0；
One DRX configuration information, including DRX cycle, and in a DRX cycle monitor down control channel time
Segment information (time migration, and/or, time span).UE each DRX configuration information indicate monitoring down control channel when
Between down control channel is monitored in section.DRX configuration information can also include the effective time range information of the DRX or effective
DRX number of repetition information.
It services scheduling of the network element after message 4 and sends the subsequent RRC state conversion for carrying instruction UE, Yi Jijie
The RRC information or MAC CE of network element authentication information.
For example, according to the method for embodiment 1, the acquisition UE uplink that service network element is sent in the anchor network element for receiving UE
After text is receiveed the response, above-mentioned RRC information or MAC CE are sent.
Due to the delay between above-mentioned service network element and anchor network element be it is relatively determining, service network element can according to
Communication history between anchor network element is it is recognised that service the setting UE that network element can be appropriate in above-mentioned message4
Monitor the time of down control channel.
Figure 15 illustrates how to implement method provided in this embodiment based on during two step RACH.It simply retouches below
It states as follows：
The access network elements for receiving message 1 send the MAC CE (UE of contention resolved by message 2
Contention Resolution MAC CE), and carrying UE monitors the time letter of down control channel in message 2
Breath.The content that the UE monitors the temporal information of down control channel is same as described above, no longer describes.
Receive the UE of message 2, if it is determined that the contention resolved that message 2 is carried is identified as the competition solution of the UE
Award of bid is known, then the UE is according to the above-mentioned temporal information for monitoring down control channel, to monitor down control channel.
As it can be seen that the present embodiment is substantially the RRC information (such as RRC resume request) that will respond UE transmission
It receives the response (such as RRC resume) and message 4 (message 2) relieves binding relationship.Under above-mentioned scene,
Service network element can send messag 4 (message 2) instruction UE contention resolved mark within the shortest time, without
It is sent after waiting interaction of the service network element between anchor network element and together with the RRC information of response UE；To contention resolved
The UE of failure can re-initiate RACH process as soon as possible, and the successful UE of contention resolved is then according to side provided in this embodiment
