Background technique
There is provided universal cellular network covering is a huge challenge, especially in subterranean zone or the indoor area of deep layer
Domain, such as urban parking area.This is mainly due to accumulations caused by the wall in these regions, floor and ceiling through loss.Bee
The deployment of nest macro network is seldom optimized for these depth coverage conditions.However, universal covering is for new automobile machine
Type communication (Machine Type Communication, MTC) use-case is particularly important, for example, for check vehicle-state,
The teleaction services such as vehicle, automatic valet parking are positioned in Public Parking.Traditional technical solution is provided based on macro-cell deployment
Covering, can be generally divided into following two categories.
First method used for Internet of Things (Internet of Things, IoT) narrowband (narrowband,
NB) technology, or it is based on the MTC of low-power wide area network (Low Power Wide Area Network, LPWAN).This includes being based on
The technology of 3GPP, such as NB-IoT (also referred to as NB-CIoT), NB-LTE, LTE-MTC, EC-GSM-IoT and non-3 gpp technology,

Particularly, which can determine from potential site 401, for example, can be used in the presumptive area 300 is stopped with known
Parking stall, and can be based on coverage metric (metric) associated with each potential site 401 and/or connection measurement.Such as
The relay node 200 of fruit vehicle 1 finally occupies the position that the potential site 401 is determined as it, then associated with potential site 401
Coverage metric can indicate such as estimation non-overlap 3D covering.If the relay node 200 into the region is finally determined
In the position that the potential site 401 is determined as it, then associated with potential site 401 connection measures that for example, may indicate that can for position
The quantity of the activity or candidate relay node 400 that can potentially be communicated with the relay node of the entrance 200.
Alternatively, the feelings being distributed in control device 100 in multiple or all relay nodes 200 in presumptive area 300
Under condition, so that it may provide potential site 401, and coverage associated with potential site 401 to the relay node 200 of vehicle 1
Amount and/or connection measurement.Then, the relay node 200 can voluntarily, or other relay nodes 200 in region 300
Support under, from potential site 401 determine final position.
Each relay node 200 in presumptive area 300 finally should be that is, each equipped with the vehicle of relay capabilities
A position is occupied in region 300, is required so that meeting covering, for example, coverage metric maximizes.But also to meet connection and want
It asks, for example, connection measurement is maintained on minimum threshold.
It is associated with each potential site 401, it is preferably also to the relay capabilities of relay node 200 and/or wanting for power consumption
It asks.Therefore, some positions may not be needed any relay capabilities (since nearby there are other active relays nodes 200 for it), and
Other positions need relay capabilities (for example, having different duty ratios, transmission power etc.) really.
Relay node 200 is movable into and out determining position (parking stall) and/or entire presumptive area 300 with the time,
Network topology structure in the presumptive area 300 can also change, and correspondingly, the relaying and/or connected state of network also can
It changes.
Selected objective target of the invention is to ensure that network remains unremitting network.That is, presumptive area 300
In each relay node 200 should be directly or indirectly connected to another service node in BS 301 or region 300 always.
Thus, it is preferable that the connected graph of network dynamic modeling should be connected without interruption.Collection can be used in control device 100
Chinese style or distributed signaling mechanism check and maintain (dynamic) connected graph.Preferred signaling mechanism is further retouched below
It states.
The example of the connected graph of nomadic junction network dynamic modeling is shown in FIG. 4, can be made by control device 100
With to ensure the connection of BS 301 or other service nodes.Each node in connected graph be BS 301 or network node,
Active relays node 200, candidate relay node 400 or conventional user devices (user equipment, UE) 402.In addition, may be used also
To preferably include position candidate 401 (that is, potential relay node position).Active relays node 200 can be connected to each other, and
And in some cases, it may be connected to more than one other active relays nodes 200.Candidate relay node 400 is exactly example
Such as, parking cars for active relays node 200 can be become, for example, making a reservation for if neighbouring active relays node 200 leaves this
Region 300 can then become active relays node 200.Preferred signaling mechanism ensures that this configuration change smoothly occurs,
In the change may need to redeploy some existing nodes in presumptive area 300, to maintain to connect continuously in connected graph
It is disconnected.
Period in connected graph indicates the redundancy of connection, for the topological structure of the variation of nomadic network, increases
The robustness of connection, especially when relay node 200 with the time is movable into and out presumptive area 300 when connection robust
Property.
The covering requirement of the configuration and/or position that can determine relay node 200 accordingly has been illustrated below and has required with being connected to
Example.
Firstly, being assumed as follows:
Ap r(t) it indicates to be covered in moment t by the 3D that the relay node r for the position p being placed in presumptive area 300 is realized
Lid.
Tp r(t) the covering collection in moment t by the UE 402 serviced of the relay node r positioned at position p is indicated.
Sp r(t) it indicates to be connected to the collection for having connected relay node 200 of the relay node r at the p of position in moment t
It closes.
SINRijIt indicates from node i to the Signal to Interference plus Noise Ratio of the transmission of node j.
If there is SINRij>βconnAnd SINRji>βconn, wherein βconnFor node connection minimum SINR threshold value, then two
Relay node i and j are connected to.
Nr p(t) it indicates to be connected to the quantity of the relay node 200 of the relay node r at the p of position in moment t.
Nconn minIt is attached to the minimum number for having connected relay node 200 of given trunk node.
Ncov minIt is that the minimum number of the relay node 200 of covering is provided to particular UE 402.
Relay node r selects the rule of position p can be as follows with formulae express in presumptive area 300:
Nr p>Nconn min(connection requires)
Ap rIt is maximized (covering requires)
Conventional UE u selects the optional rule of position p can be as follows with formulae express in presumptive area 300:
u∈Tp r, for Ncov minA difference node r=r1,r2..Ncov min(covering redundancy)
NR=u p=min (1, Nconn min) (relaying disposition optimization)
Wherein assume that u is the UE 402 at the position p in presumptive area 300.
Two kinds of preferred signaling mechanisms are described below, are alternatively used for for example, by multi-hop relay node scene
In (dynamic) figure be connected to realize and maintain unremitting network.
In Fig. 5 and centralized mechanism shown in fig. 6, control device 100 determines the relay node for reaching presumptive area 300
200 optimum position and/or configuration (shown in Fig. 5) are based on to meet covering and/or connection target, i.e. control device 100
Covering and/or connection require to determine position.In the case where relay node 200 leaves presumptive area 300 (shown in Fig. 6),
Control device 100 also determines configuration and/or the position of relay node 200.Centralized mechanism has the advantage, that grasp pre-determining
Overlay area 300 global view, and grasp the network coverage and the integrality that is connected to.
Referring to Fig. 5, the case where reaching with vehicle 1 presumptive area 300 together for new relay node 200, centralization is described
Signaling mechanism.When the relay node 200 of vehicle 1 enters region 300, it can send triggering and give service BS 301, to convey
Its event for entering region 300.Triggering and relay node context can will be updated by servicing BS 301, such as relaying ID (can be with
Be mapped to trunk type and relay capabilities), parking lot ID and/or battery status, be transmitted to together control device 100 (referred to here as
For control unit).
Then, based on including relay node context, existing covering, existing connection and/or from such as intelligent transportation system
The standard of the connection requirement that (Transportation System, ITS) App 500 is obtained etc., control device 100 can determine
The best parking position of vehicle 1, that is, optimum position of the relay node 200 reached in presumptive area 300.Control device 100 is also
It can determine the configuration of the relay node 200 of arrival.Configuration can be sent to the relay node 200 of arrival, such as pass through clothes
Business BS 301 is sent.The configuration of the relay node 200 of arrival may include and parameter like below: repeater mode, definition
How other nodes (e.g., including the operation of relays of such as AF or DF, band outer or with interior relaying), UE mould are relayed information to
The ID of formula, wireless resource management configuration (for example, Tx power, antenna mode, frequency band) and/or neighbouring relay node 200.So-called neighbour
Nearly relay node 200, refers to that the relay node 200 of arrival should establish the 200 (example of relay node for being relayed to repeated link therewith
Such as, it is established with vehicle 2 and/or vehicle 3).
In addition it is also possible to which the currently active 3D map of presumptive area 300 to be sent to the relay node 200 of arrival.Herein
On the basis of, the position in presumptive area 300 can be designated as the coordinate on provided 3D map, or be designated as opposite
In the relative position for the relay node 200 arbitrarily parked.In addition to this, which can also be defined as wireless parameter, for example,
Come connecing for relay node 200 park self, with given relaying ID, that reliable Radio Link connection can be established therewith
Receive signal power.For example, when receiving power level reaches given threshold value or more, so that it may it is assumed that in place.
The relay node 200 of arrival executes the received configuration of institute, such as arrives another 200 (example of relay node by establishing
Such as, the relay node 200 of automobile 3) communication link execute.Once establishing communication link, the relay node of newly arrived vehicle 1
200 are assured that current covering, for example, by from the 402 collecting signal quality measured values of UE having connected, or pass through
It uses, for example, the parking sensor of distance and/or Tx power level for measuring surrounding objects is estimated to cover.Then,
Covering can be updated and be sent to service BS 301 by existing communication link.Therefore, in centralized mechanism, pass through covering
More newly arriving indicates new 200 configuration successful of relay node.
Referring to Fig. 6, the case where leaving presumptive area 300 for relay node 200, centralized signaling machine is further described
System.When relay node 200 (for example, relay node of vehicle 3) leaves region 300, the relay node 200 to be left can be sent
It triggers and gives service BS 301, so as to the event for conveying it to leave region 300.The triggering can be in the engine start of such as vehicle 3
Or targetedly location input vehicle 3 navigation system when generate.Then, triggering message is sent to service BS 301, preferably
It is sent via the network for the relay node 200 having connected for maintaining the connection, alternatively, logical with service BS 301 when can establish
When believing link, it can also directly transmit.Servicing BS 301 can send to control device 100 by the triggering, it is preferable that simultaneously also
Send relay node context as described above.Then, control device 100 determines required update on such as connected graph.
Here consider two example options: determining one of existing relay node 200 (for example, relay node 200 of vehicle 1)
New position, to maintain connected graph.Alternatively (or additionally), from available, current inactive candidate relay node 400
New active relays node 200 is configured, so that maintaining connected graph free of discontinuities.
This second selection is shown in FIG. 6.Therefore, new relay node is configured to the service relay node 200 via vehicle 1
It is sent to the candidate relay node 400 for being currently at the vehicle 2 of UE mode.Then, it is by the activation of candidate relay node 400 of vehicle 2
Relay node 200 establishes the communication link between vehicle 1 and vehicle 2.Once establishing the communication link between vehicle 1 and vehicle 2, just
It can be sent to vehicle 3 and leave ACK, such as by control device 100 by service BS 301 and eventually by other have connected
It is sent after node 200.When vehicle 2 is activated as new relay node 200, the covering of update detailed above is determined that, and
Covering is updated and is sent to control device 100, preferably via in connected graph service BS 301 and relay node 200 send.
It is updated based on the covering, the currently active 3D map of 100 update area 300 of control device.
It, can be with it should be noted that part or all or its control function of the control device 100 mentioned in Figures 5 and 6
In another service node in BS 301 or region 300, but it can also be located in random access net (RAN) congruent point, or
Person is located in ITS App 500.
In distributed mechanism as shown in Figure 7 and Figure 8, for trunking configuration, node locating and the control being connected to is maintained
Device 100 is distributed on several relay nodes 200, so that the self-organizing for generating nomadic relay node 200 is interim (ad-hoc)
Network collaboratively ensures the connection between each relay node 200 and the BS 301 of network.That is, control device 100
It is distributed on multiple relay nodes 200.
Referring to Fig. 7, describe distributed signaling mechanism for following situation: relay node 200 (together with vehicle 1) enters
Presumptive area 300 (being parking lot here) sends to BS 301 and indicates, then the currently valid environmental map in receiving area 300,
Preferably also receive the information of active relays node 200.The environmental map preferably includes (the candidate parking stall of potential site 401
Set), this depends on such as relay capabilities of vehicle 1, its expected parking duration (if any) and its battery status.About active relays
The information of node 200 may include to service the timing of BS 301 as the network identity and biography of the active relays node 200 of reference
Defeated scheduling.
All active relays nodes 200 can be broadcast periodically the environmental map of themselves version, including it is available and
Suitable position 401, this depends on state (the i.e. relay capabilities, expected parking duration, battery of relay node 200 to be added
State).The transmitting and scheduling of active relays node 200 and period can be pre-configured with by network, or can be by relay node 200
It is selected from limited one group of possibility in decentralized manner.
Any relay node 200 can sense and monitor the covering of BS 301.Once there is such as vehicle 1 to sense BS 301
Covering lower than specific threshold (for example, being measured based on RSSI or RSRP), so that it may broadcast immediately its own status information (in
After ability, expected parking duration, battery status etc.).It then, (is herein the activity of vehicle 2 by nearest active relays node 200
Relay node 200) information is received, which can update the periodic broadcast of their own, include wherein
The new information.The update by the covering of vehicle 2 at least one active relays node 200 (for example, vehicle 3) and it is other it is inactive in
It is received after node 400 and non-relay nodes.Other active relays nodes 200 (being the relay node of vehicle 3 here) can be by it
It (is the relay node of vehicle 1 here, extensively by vehicle 2 that the environmental map of the update of oneself, which is broadcast to nearest active relays node 200,
Broadcast), the latter then updates the environmental map broadcast of their own.Then, vehicle 1 has connected the chain of the composition of relay node 200 by this
The wider environmental map of all active relays nodes 200 in receiving area 300 updates.
The final position of vehicle 1 and its relay node 200 determines by its own, be based preferably on obtain as described above it is cumulative
With fused Environmental Map Information.Once vehicle 1 and its relay node dock to determining position, relay node 200 will just be wrapped
Instruction containing the position is sent to nearest active relays node 200, which is relayed to BS then via multi-hop relay by the latter
301。
Referring to Fig. 8, the case where leaving presumptive area 300 for relay node 200, distributed signaling mechanism is described.?
In distributed signaling mechanism, following steps have been marked.
Leave the relay node 200 (belonging to vehicle 2 herein) of presumptive area 300 to for example its adjacent to active relays node 200
Instruction is sent, then identifies suitable replacement person again for its own.This can based on being triggered by service relay node 200 or
By the on-demand or periodic measurement report of UE 402 (such as UE of the vehicle 3) initialization serviced.The measurement report is not limited to
Signal quality measured (such as RSSI, RSRP) can also include that vehicle-state is reported, include relay capabilities, battery capacity, expection
Duration of stopping etc..
Once the relay node 200 to be left determines suitable replacement person, is just configured and activated newly to relay section
200 (for example, relay nodes of vehicle 3) of point, and the active relays node 200 (such as relay node of vehicle 1) connected to it
Notify this operation.When receiving trunking configuration and activation command from its service relay node 200, the new relay node 200 is just
Link is established with old relay node 200 and at least one the active relays node 200 for being connected to the old relay node 200.
The active relays node 200 for being connected to the relay node 200 to be left is being received from new relay node 200
When communication, confirmation just is sent to the relay node 200 to be left.The active relays node 200 newly configured starts periodic broadcast
Its environmental map updated, and the UE 402 in its overlay area is then finally according to their sleep-awake period, by they from
Body is associated with the relay node 200 newly activated.
If can satisfy covering without suitable relay node 200 and/or connection require, the relay node to be left
Option there are two 200: the active relays node 200 for notifying it to connect finds suitable replacement person, in this case, finds conjunction
The process of suitable replacement repeats at these relay nodes 200；Or instruction candidate relay node 400 is moved to suitable position
401, it makes it possible to satisfaction covering and/or connection requires.
In the table shown in Fig. 9, the present invention and traditional narrow LPWAN technical solution (i.e. NB-IoT) and base are given
In the qualitative comparison of the technical solution (such as multi-hop fixed relay) of proprietary infrastructure.As can be seen that using the present invention, well
Existing infrastructure is utilized, and the technical solution based on proprietary infrastructure fails to accomplish.In addition, the present invention is enough to realize
Depth in-door covering, and meet automotive remote service use-case in the case where no extra cost, and narrowband LPWAN technical side
Case but fails to accomplish.In addition, although these are not delayed key (delay- invention introduces new signaling mechanism
Critical).
In addition, particular condition in use of the invention can be applied by being described below.
One use-case be intelligence covering expansion module as shown in Figure 10 (Coverage Extension Module,
ICEM).Its proposition aims at the new 5G feature that control device 100 according to an embodiment of the present invention is embodied as in ICEM.Therefore, " intelligence
Energy covering extension " (ICE) can be embodied as software module on existing NB-IoT or LTE (- M/Cat0) modem.So
What is obtained is traditional NB-IoT or LTE-M/Cat0 modem with intelligence covering expansion module (ICEM), according to base
In the ability of the control device 100 of the embodiment of the present invention, the covering extension of intelligence and enhancing is provided.
Another use-case is (the Dynamic Radio Environment of dynamic wireless environments map shown in Figure 11
Map, DREM).The suggestion use-case requires nomadic nodes (relay node 200 or other) to carry out wireless measurement, and constructs predetermined
The wireless environment map in region 300, to participate in the program.These environmental maps are also referred to as dynamic wireless environments map (Local
DREM, LDREM), it is dynamic as its name suggests, because they at any time and spatial variations, and can be based on wireless measurement.
Consider the concrete scene of Figure 11, it illustrates the plan view of presumptive area 300 (being parking lot here), each positions
(the being parking stall here) A30 that is marked as A1 ....Shade vehicle is the relay node 200 (nomadic) of current active, is it
Its vehicle provides covering extension.In Figure 11, the covering that the active relays node 200 at the A17 of position provides is particularly illustrated.
The triggering of relay node 200 of each positioning services the wireless measurement of user (D2D) from it, to construct local dynamic station
Wireless environment map (LDREM).Why it is " part ", is because measurement is to have parked relay node 200 what is discussed
Locally carry out.For example, the LDREM of the relay node 200 at the A17 of position is appeared likely to as shown in the top half of Figure 12.
Top half in Figure 12 includes relay node 200 at the A17 of position relative to position A1 ... A16, A18 ...
The wireless measurement of other nodes at A30, here it is illustrative RSSI (dBM) for the wireless measurement.Top half includes sky
Position, depending on the size and occupancy in region 300, masking etc..
Since (that is, forming unremitting connected graph) all active relays nodes 200 should be connected, without in activity
It is isolated or disconnects after node 200.Active relays node 200 can share their own LDREM, and can construct
The global dynamic wireless environments map (Global Dynamic Radio Environment Map, GDREM) in region 300, such as
Shown in the lower half portion of Figure 12.This GDREM being made into of pooling our ideas and make concerted efforts can provide the complete RF fingerprint in region 300, including latent
Empty wagon position 401, and/or active relays node 200 on load.Additional contextual information can also be supplemented, such as
Node capacity, the parking duration of estimation, battery status etc..GDREM can be used as to relay concentration/distribution formula presented above and save
The input of point 200 deployment and configuration mechanism.LDREM/GDREM optionally can integrate third party's map or sensor measurement (such as
Fruit is available), to obtain more fine-grained environmental map.
In short, the present invention compares conventional solution, especially traditional LTE for being only designed for double bounce communication is relayed,
Realize following difference.Traditional scheme does not support multi-hop, it can hop count be no more than double bounce.In addition, not having in LTE relaying
There is the auto-mechanism for establishing multi-hop.Battery consumption is not considered, because usually there is fixed power supply.In addition, the mode of relay node
It is fixed in LTE relaying, i.e., be not AF is exactly DF.
On the contrary, can support to be more than double bounce using the present invention, and relay node 200 can be based on covering and/or connection
It is required that carrying out configuration mode.Relay node 200 also can be configured as UE 402.In addition, the repeater mode between relay node 200
It can be determined based on information element (for example, the measured value being collected into) and battery status with being connected to.
It has been combined various as exemplary embodiment and embodiment and describes the present invention.However, art technology
Personnel, can be by research attached drawing, the disclosure and independent claims, to understand when practicing the claimed invention
With the other modifications of realization.In claims and specification, one word of " comprising " is not excluded for other element or step, and not
