Positioning is put or deployment position reads related system message, but because the system message of broadcast has certain periodicity, it is impossible to
Receive immediately, the reception time can be caused longer, 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 obtains new SIA system message by dedicated signaling process.For example, if the system message
It is more urgent, UE there is no the system message can not then carry out normal work, this kind of system in the TRP under new SIA
Message, it is adapted to notify that now these system messages can be together with the information for switching TRP to UE in a manner of dedicated signaling immediately
UE is sent to, can be RRC signaling process.Equivalent to, UE changes TRP in a SIA, can be signaled with L1/L2, and
When UE across SIA but belong between CMA TRP change when, if necessary to notify the system message or more of letter with RRC signaling
Configuration is changed, has then needed to use RRC signaling process, while notified new system message and TRP to change, if not needing RRC signaling
Process, then it can still use L1/L2 signalings.
Acquisition modes three, UE obtain new SIA system message by way of 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, just notify just to obtain wherein all SIA system message when being moved to the CMA to UE, such as UE by RRC signaling, can
To be carried in switching command.Afterwards, when UE is moved to the SIA, it is only necessary to which L1/L2 signals UE replacings and arrives target TRP
, obtained in advance in the affiliated SIA of target TRP system message.
Embodiment three
The present embodiment describes the process of Region control when Idle state UE is moved in the system message region.
In the present embodiment, SIA regions are planned by network side, are usually semi-statically configured, i.e., initially according to planning,
All TRP in set 1 belong to SIA1 regions, and all TRP in set 2 belong to SIA2 regions, etc..Needed when finding to configure
It during change, then can be changed, such as the TRP for changing SIA regions is first shut down, then starting shooting again is reconfigured to be new
SIA regions.If necessary to change of starting shooting, then need to follow certain modification cycle, and notify UE to change.TRP and SIA regions
Mapping relations, carried by explicit signaling, can be following manner：
SIA ID (SIA marks), such as synchronizing signal is carried in-synchronizing signal to scramble with SIA ID；
- broadcast notice synchronizing signal and the mapping relations in SIA regions.
All TRP that network side planning belongs to a SIA region use identical system message, and these TRP are ginseng a bit
Broadcast with system message is transmitted, and some TRP may only support the request method of system message to send.One kind is realized as follows：
The system message broadcast transmission that the certain TRP of the network planning is synchronized, in general, these TRP combination 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 ensure that these TRP can be simultaneously with identical on interface in the air
Resource sends identical content.The system message that broadcast mode is sent may only be partial content, and the content of also more details can
Sent in the mode by dedicated mode or multicast, narrowcast.
When UE starts shooting, or moves into a new SIA region by other regions, UE processes are as follows：
- UE searches for synchronizing signal first, and basic down-going synchronous process is established 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 is moved, if UE is moved under another TRP covering by TRP covering, UE process
It is as follows：
First, UE detects that new TRP received signal strength or the quality of reception signal calculate in predetermined 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 TRP (alternatively referred to as sources according to the information of acquisition
TRP a SIA region) whether is belonged to, if belonging to same SIA regions, UE continues to be resident, and is using what is obtained
Message of uniting carries out various operations；If being not belonging to same SIA regions, UE thinks to have changed SIA regions, at this time needs weight
The system message in new SIA regions is newly read, and according to circumstances judges whether to be adapted to be resident.
The information of above-mentioned acquisition can be TRP and SIA regions mapping relations, and the mapping relations can be led to by the network equipment
Know to UE.
Example IV
The present embodiment describes when connected state UE is moved in CMA or the process of Region control during across CMA movement.
Network typically configures which TRP belongs to a CMA by semi-static mode.The preplanning of initialization is good and complete
Into configuration, the CMA after TRP starts then according to configuration starts working.Centre finds to need to match somebody with somebody the CMA of TRP ownership again
When, a kind of mode is that TRP shuts down, and new configuration is performed again after start, and another way is to take certain modification cycle,
New CMA configurations are performed in modification cycle boundary, and the UE of correlation is notified.
Access relevant parameter in UE configures according to system message, initiate Stochastic accessing, connection is established after process, UE
Into connected state.In general, UE and need not clearly know which TRP belongs to a CMA because connected state be completely by
What network side was controlled, network controls UE process, therefore CMA and TRP mapping relations, it is not necessary to broadcast signaling etc.
Mode is notified, that is to say, that Idle state UE is not aware that CMA scope.Network side can control UE when carry out TRP it
Between L1/L2 handoff procedures, when carry out the L3 handoff procedures in CMA regions.
, can be from different measurement configurations for connected state UE, implicit knows which TRP is in 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 CMA TRP needs L3 to filter, or the parameter of measurement filtering is different.
Illustrate two kinds of different mobile process individually below：
The movement between TRP inside 1, CMA of scene：
First, network needs the measurement to UE configurations TRP, and UE configures according to measurement, constantly includes clothes to neighbouring TRP
Business TRP carries out channel link detection, and when meeting report condition, result is reported into network side, and the report condition can be week
Phase property, which is reported or worked as, meets that threshold value reports, such as reaches threshold value and dimension higher than service TRP adjacent to TRP measured values
Reported when holding certain time length.
Alternatively, also a kind of mode, is reported not by UE measurements, and passes through inspection of the network side to up-link
Survey, to determine the most suitable TRP to UE services.
No matter UE is reported or network voluntarily detects, and after network collection is to measurement result, is judged if necessary to change
Current service node, then need quickly to notify UE service TRP changes with L1/L2 signalings, at the same in source and target TRP or
Between TRP groups, the transmission of UE contexts and data is carried out, in order to which UE can obtain continuous service in new TRP；
After UE receives service TRP changes, start to be transmitted with new TRP.
Scene 2, the movement between CMA TRP：
In this fashion, the measurement for being generally based on UE is reported and triggered, and certain network can also be with load balancing
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：UE measurement reported result is received, and measurement reported result is judged, if meeting across CMA switching
Condition, then initiate switching set-up procedure to target CMA control node, target CMA control node can be a concentration
Control node or on a Distributed T RP；
Step 3：When target CMA has replied the configuration received successfully and to UE, then UE switching command is sent to UE；
Step 4：Release signaling is received, discharges UE contexts.
UE sides process：
Step 1：UE receives the related measurement configuration of network side；
Step 2：Measured according to configuration, and corresponding L3 is filtered, and measurement result is reported to the standard of triggering with measurement
Then it is compared, when reaching the condition that measurement reports, measurement result is reported into network side；
Step 3：Switching command is received, access procedure is initiated to the target TRP under target CMA, is switched to target side progress
Work, and feed back switching to destination node and complete signaling.
Embodiment five
When CMA is more than SIA, it is assumed that CMA can include two or more SIA.For Idle state UE,
Because can only see SIA scope, therefore the process (such as embodiment three) of Idle state is still performed, do not stated herein deposited.
For connected state UE, when UE occur across CMA it is mobile when, process be similar to example IV in across CMA shifting
Dynamic process, no longer apply state herein.
When UE is moved in a CMA, if former TRP and target TRP belong to a SIA, then process is also similar to that
Moving process in example IV in a CMA, do not stated herein deposited.
When movements of the UE in a CMA, and when former service TRP and target TRP belongs to different SIA regions, process
There is certain particularity：
In terms of measurement, TRP is compared with the signal between target TRP for service, may when target TRP belongs to different SIA
Situation with belonging to a SIA, have different configuration, such as identical SIA situation, it may be required that target TRP ratio takes
The high first predetermined value of TRP signal intensities (such as 2dB) can of being engaged in meets the condition changed；And situations different SIA, may
Ask target TRP ratio service the high second predetermined value of TRP signal intensities (such as 3dB) could calculate satisfaction replacing 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 of identical SIA, process is relatively simple,
And it is more across the signaling that SIA needs, therefore condition is somewhat 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
Change to the target TRP under new SIA and go to service, then except 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 by way of receiving and being broadcasted in new SIA, can obtain new SIA system message, and this process is similar to sky
Not busy state UE processes, related system message is read in ad-hoc location or deployment position, but because the system message of broadcast has one
Fixed periodicity, it is impossible to receive immediately, it is longer to cause to receive the 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 can not then carry out normal work in the TRP under new SIA, this category information, be adapted to immediately with special
The mode of signaling notifies that to UE now these information can send jointly to UE with switching TRP information, can be RRC signaling
Process.Equivalent to, UE changes TRP in a SIA, can be signaled with L1/L2, and when UE across SIA but belongs to a CMA
TRP between when changing, if necessary to notify the system message of letter with RRC signaling or have changed configuration, then need to use RRC
Signaling procedure, while notify new system message and TRP to change, if not needing RRC signaling process, it can still use L1/
L2 signalings.
- UE obtains new SIA system message by way of network side configures in advance.For example, for may relate to
SIA more urgent system message, 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 wherein all SIA system message when being moved to the CMA to UE, such as UE, can switch
Carried in order.Afterwards, when UE is moved to the SIA, it is only necessary to which L1/L2 signals UE replacings and arrives target TRP, in mesh
The affiliated SIA of mark TRP system message obtains in advance.
Embodiment six
When CMA is less than SIA, connected state UE is moved in whole CMA, and each TRP belongs to identical SIA, and system disappears
Breath is that identical or part are identical, then for UE, it may not be necessary to has 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 UE former TRP, because
In the case of identical SIA, UE can not have to reacquire system message for this, and if belonging to different SIA, then need UE to obtain
New system message, ordinary circumstance are to be transmitted directly to UE by switching command by network side.
