Fruit, such as UE include constantly that service TRP carries out channel link detection to neighbouring TRP according to configuration.
For being applicable in above-mentioned UE by the notice of the RRC signaling acquisition network equipment, executes from source TRP and be switched to target TRP
Handoff procedure scene:
Range of the range of one CMA less than a SIA, the source TRP and target TRP are located at the same SIA；Or
Range of the range of one CMA less than a SIA, the source TRP and target TRP are located at different SIA；Or
The range of one CMA is identical as the range of a SIA, and the source TRP and target TRP are located at different SIA；Or
The range of one CMA is greater than the range of a SIA, and the source TRP and target TRP are located at different SIA.
That is, source TRP and target TRP be not in a CMA in above-mentioned scene.
In above-mentioned scene, if source TRP and target TRP is located at different SIA, the method also includes:
The UE obtains the system message of the new SIA corresponding to the target TRP.
Acquisition modes one: UE obtain the system message of new SIA by way of receiving and broadcasting in new SIA；Such as UE can be with
By way of receiving and broadcasting in new SIA, the system message of new SIA is obtained, this process is similar to Idle state UE process, in spy
Positioning is set or deployment position reads relevant system message, but since the system message of broadcast has certain periodicity, cannot
It receives immediately, it is longer to will lead to receiving time, this mode, suitable for the information insensitive to time delay, such as MBMS
(Multimedia Broadcast Multicast Service, multimedia broadcast multicast services) relevant information etc..
Acquisition modes two: UE obtain the system message of new SIA by dedicated signaling process.For example, if the system message
Be it is more urgent, UE there is no the system message cannot then be worked normally in the TRP under new SIA, this kind of system
Message, suitable to be notified in a manner of dedicated signaling immediately to UE, these system messages can be together with the information of switching TRP at this time
It is sent to UE, can be RRC signaling process.It being equivalent to, UE converts TRP in a SIA, it can be signaled with L1/L2, and
When UE across SIA but belong to a CMA TRP between convert when, if necessary to the system message or more of RRC signaling notice letter
Configuration is changed, has then needed using RRC signaling process, while new system message and TRP being notified to convert, if you do not need to RRC signaling
L1/L2 signaling then still can be used in process.
Acquisition modes three, UE obtain the system message of new SIA in such a way that network side configures in advance.For example, for can
The more urgent system message for the SIA that can relate to, network side can be allocated to UE in advance, i.e., UE be moved to the SIA it
Before, it just notifies just to obtain the system message of wherein all SIA when being moved to the CMA to UE, such as UE by RRC signaling, it can
To be carried in switching command.Later, when UE is moved to the SIA, it is only necessary to which L1/L2 signals UE replacement to target TRP
, obtained in advance in the system message of the affiliated SIA of target TRP.
Embodiment three
The present embodiment describes the process of the control of region when Idle state UE is moved in the system message region.
In the present embodiment, the region SIA is planned by network side, is usually semi-statically configured, i.e., initially according to planning,
All TRP in set 1 belong to the region SIA1, and all TRP in set 2 belong to region SIA2, etc..When discovery configuration needs
It when change, then can change, such as the TRP for changing the region SIA is first shut down, then be switched on again and be reconfigured to be new
The region SIA.If necessary to the change that is switched on, then need to follow certain modification period, and UE is notified to change.TRP and the region SIA
Mapping relations are carried by explicit signaling, can be such as under type:
SIA ID (SIA mark) is carried in synchronization signal, such as synchronization signal is scrambled with SIA ID；
The mapping relations of broadcast notice synchronization signal and the region SIA.
Network side planning belongs to all TRP in the region SIA using identical system message, these TRP are ginseng a bit
Broadcast with system message is transmitted, some TRP may only support the request method of system message to send.One kind is accomplished by
The system message broadcast transmission that the certain TRP of the network planning is synchronized, in general, the combination of these TRP can
To provide continuous covering to UE.Network side is by centralized node come the TRP of these broadcast transmissions of centralized control, transmission system message
These TRP are given in content and sending method, transmission resource distribution, to guarantee that these TRP can be simultaneously with identical on interface in the sky
Resource sends identical content.The system message that broadcast mode is sent may be only partial content, and there are also the contents of more details can
It is sent in the mode by dedicated mode or multicast, narrowcast.
When UE is switched on, or moves into a new region SIA by other regions, UE process is as follows:
- UE searches for synchronization signal first, establishes basic down-going synchronous process with network side；
- UE reads broadcast system message, obtains the essential information in the region, if appropriate, is then resident on the area.
When UE occurs mobile, if UE is moved under the covering of another TRP by the covering of a TRP, the process of UE
It is as follows:
Firstly, UE detects that the received signal strength of new TRP or the quality of reception signal are calculated in scheduled configuration
Under mode, better than original TRP, then UE can be moved to new TRP；
UE judges new TRP (alternatively referred to as target TRP) and original (the alternatively referred to as source TRP according to the information of acquisition
TRP) whether belong to the region SIA, if belonging to the same region SIA, UE continues to be resident, and is using what is obtained
Message of uniting carries out various operations；If being not belonging to the same region SIA, UE thinks to have replaced the region SIA, at this time needs weight
The system message in the new region SIA is newly read, and according to circumstances judges whether to be suitble to resident.
The information of above-mentioned acquisition can be the mapping relations of TRP Yu the region SIA, which can be led to by the network equipment
Know to UE.
Example IV
The present embodiment describes the process of the control of region when connected state UE is moved in CMA or when across CMA movement.
Network generally configures which TRP belongs to a CMA by semi-static mode.The preplanning of initialization is good and complete
At configuration, then start to work according to the CMA of configuration after TRP booting.Centre discovery needs the CMA belonged to TRP to be reconfigured
When, a kind of mode is that TRP shuts down, and executes new configuration again after booting, and another way is to take certain modification period,
New CMA configuration is executed in modification cycle boundary, and relevant UE is notified.
When the access relevant parameter during UE is configured according to system message, after initiating random access, connection establishment process, UE
Into connected state.In general, UE does not need explicitly to know which TRP belongs to a CMA because connected state be completely by
What network side was controlled, the process of network controls UE, therefore the mapping relations of CMA and TRP, it does not need with broadcast signaling etc.
Mode is notified, that is to say, that Idle state UE is not aware that the range of CMA.Network side can control UE when carry out TRP it
Between L1/L2 handoff procedure, when carry out the L3 handoff procedure in the region CMA.
, can be from different measuring configurations for connected state UE, implicit knows which TRP is in the same CMA
Portion, the measurement result for the different TRP which TRP belongs to inside the TRP across CMA, such as a CMA does not need L3 filtering, and
Measurement result between TRP across CMA needs L3 to filter, or the parameter of measurement filtering is different.
Illustrate two different mobile process individually below:
The movement between TRP inside 1, CMA of scene:
Firstly, network needs to configure the measurement of TRP to UE, UE includes constantly clothes to neighbouring TRP according to measuring configuration
Business TRP carries out channel link detection and result is reported to network side when meeting report condition, which can be week
Phase property reports, and threshold value ought be met by, which being also possible to, reports, such as is higher than service TRP adjacent to TRP measured value and reaches threshold value and dimension
It is reported when holding certain time length.
Optionally, there are also a kind of modes, report not by UE measurement, and pass through inspection of the network side to uplink
It surveys, to determine the most suitable TRP serviced to UE.
No matter UE is reported or network voluntarily detects, and after network collection is to measurement result, judgement is if necessary to replace
Current service node, then need quickly to notify UE service TRP change with L1/L2 signaling, at the same in source and target TRP or
Between TRP group, the transmitting of UE context and data is carried out, in order to which UE can obtain continuous service in new TRP；
After UE receives service TRP change, start to be transmitted with new TRP.
Movement between scene 2, the TRP across CMA:
In this fashion, the measurement for being generally based on UE, which reports, to be triggered, and certain network can also be with load balancing
It is actively triggered Deng for the purpose of and UE is switched under other CMA.
Network side process is as follows:
Step 1: network needs to configure corresponding measurement to UE；
Step 2: receiving the measurement reported result of UE, and measurement reported result is judged, if meeting across CMA switching
Condition, then initiate switching preparation process to the control node of target CMA, the control node of target CMA can be a concentration
Control node is also possible to be located on a Distributed T RP；
Step 3: when target CMA has replied the configuration received successfully and to UE, then the switching command of UE being sent to UE；
Step 4: receiving release signaling, discharge UE context.
The side UE process:
Step 1:UE receives the relevant measuring configuration of network side；
Step 2: being measured according to configuration, and corresponding L3 filtering, measurement result and measurement are reported to the standard of triggering
It is then compared, when reaching the condition that measurement reports, measurement result is reported to network side；
Step 3: receiving switching command, initiate access procedure to the target TRP under target CMA, be switched to target side progress
Work, and feed back switching to destination node and complete signaling.
Embodiment five
When CMA is greater than SIA, it is assumed that CMA may include two or more SIA.For Idle state UE,
Because can only see the range of SIA, the process (such as embodiment three) of Idle state is still executed, is not stated herein deposited.
For connected state UE, when mobile across CMA occurs for UE, process is similar to across CMA shifting in example IV
Dynamic process, no longer applies state herein.
When UE is moved in a CMA, if original TRP and target TRP belong to a SIA, process is also similar to that
Moving process in example IV in a CMA is not stated herein deposited.
When movement of the UE in a CMA, and when former service TRP and target TRP belongs to the different regions SIA, process
There is certain particularity:
In terms of measurement, TRP is serviced compared with the signal between target TRP, it, may when target TRP belongs to different SIA
The case where with a SIA is belonged to, has different configuration, such as the case where identical SIA, it may be required that target TRP ratio clothes
The business high first predetermined value of TRP signal strength (such as 2dB) can meet the condition of replacement；And SIA different situations, it may
Ask target TRP ratio service the high second predetermined value of TRP signal strength (such as 3dB) could calculate satisfaction replace condition, and if
There is the requirement of duration, it is also possible to which the duration requirement of the latter is higher.In the case where identical SIA, process is relatively simple,
And it is more across the signaling that SIA needs, therefore condition is slightly higher, to avoid table tennis problem.
In terms of implementation procedure, when UE has reported the measurement result across SIA, network carries out comprehensive descision, if it is determined that by UE
It replaces to the target TRP under new SIA and goes to service, then in addition to original L1/L2 signals UE, UE also needs to obtain new SIA
Related system message.The mode that UE obtains system message is as follows:
- UE can obtain the system message of new SIA by way of receiving and broadcasting in new SIA, this process is similar to sky
Not busy state UE process reads relevant system message in specific position or deployment position, but since the system message of broadcast has one
Fixed periodicity cannot receive immediately, and it is longer to will lead to receiving time, this mode, suitable for the information insensitive to time delay,
Such as MBMS (Multimedia Broadcast Multicast Service, multimedia broadcast multicast services) relevant information
Deng；
- UE can also obtain the system message in new SIA by dedicated signaling process, if the information is more urgent
, UE there is no the information cannot then be worked normally in the TRP under new SIA, this category information, be suitble to immediately with dedicated
The mode of signaling notifies that UE, these information can send jointly to UE with the information of switching TRP at this time, can be RRC signaling
Process.It being equivalent to, UE converts TRP in a SIA, it can be signaled with L1/L2, and when UE across SIA but belongs to a CMA
TRP between when converting, if necessary to the system message of RRC signaling notice letter or have changed configuration, then need using RRC
Signaling procedure, while new system message and TRP being notified to convert, if you do not need to RRC signaling process, then still can be used L1/
L2 signaling.
- UE obtains the system message of new SIA in such a way that network side configures in advance.For example, for may relate to
The more urgent system message of SIA, network side can be allocated to UE in advance, i.e., before UE is moved to the SIA, just pass through
RRC signaling notifies just to obtain the system message of wherein all SIA when being moved to the CMA to UE, such as UE, can switch
It is carried in order.Later, when UE is moved to the SIA, it is only necessary to which L1/L2 signals UE replacement to target TRP, in mesh
The system message of the mark affiliated SIA of TRP obtains in advance.
Embodiment six
When CMA is less than SIA, connected state UE is moved in entire CMA, and each TRP belongs to identical SIA, and system disappears
Breath is identical or part is identical, then for UE, it may not be necessary to have operation bidirectional, in the CMA of upper example IV
Mobile process is similar.
And when UE occur across CMA movement when, due to CMA outside TRP be possible to belong to identical SIA with the former TRP of UE, because
The case where this is for identical SIA, UE can not have to reacquire system message, and if belonging to different SIA, need UE to obtain
New system message, ordinary circumstance are to be transmitted directly to UE by switching command by network side.
