Abstract
The invention discloses relaying Activiation method and the device of UE under a kind of D2D scene, it is related to communication technical field, the present invention determines the UE being suitable as relaying by the reporting information according to each UE, send relay activation instruction to the described UE being suitable as relaying, so that the UE receiving described relay activation instruction starts the pattern that relaying finds, thus UE only can just start, after receiving described relay activation instruction, the pattern that relaying finds, decrease unnecessary UE energy expenditure, avoid the problems such as resource contention and network interferences, simultaneously, because relay activation instruction is sent by base station, so base station can fully understand and controlling network in relaying UE quantity, it is easy to management and the efficient utilization of Radio Resource.
Description
Technical field
The present invention relates to communication technical field, particularly to relaying UE under a kind of D2D scene
Activiation method and device.
Background technology
In order to further expand the network coverage, third generation partner program (3GPP) is at present
Studying D2D (Device-to-Device) relaying technique of terminal to network, based on Rel-12
D2D communication technology, remote user equipment (User Equipment, UE) can pass through
Relaying UE realizes the communication with base station.As shown in figure 1, when the chain between far-end UE and base station
During the degradation of road, far-end UE can select suitably to relay UE, by UE-to-Network
Relaying technique ensures the seriality of business.
3GPP defines the pattern that two kinds of relayings find at present.Mode A, relays the UE cycle
Property send relay discovered message, this pattern can continuously consume Radio Resource and relaying UE
Power supply.Mode B, far-end UE sends relay request message first, and relaying UE is anti-after receiving
Feedback relay discovered message is as response.
For the UE of Mode A, long time period may be faced and send relay discovered message,
But far-end UE is not selected as relaying, and this situation can cause unnecessary UE energy
Amount consumes, and also brings along the problems such as discovery resource contention and network interferences.Meanwhile, if be in
UE under idle condition constantly sends relay discovered message, and base station will be unable to fully understand and controls
The quantity of the relaying UE in network processed, is unfavorable for management and the efficient utilization of Radio Resource.

With reference to the accompanying drawings and examples, detailed further to the specific embodiment work of the present invention
Description.Following examples are used for the present invention is described, but are not limited to the scope of the present invention.
Fig. 2 be one embodiment of the present invention D2D scene under relay UE Activiation method
Flow chart；With reference to Fig. 2, methods described includes：
S201：Receive the reporting information of each UE；
It should be noted that the executive agent of the method for present embodiment is base station, so, phase
Ying Di, each UE are the UE in described base station range.
It will be appreciated that described reporting information is for reflecting user equipment current network state
Information, in present embodiment, described reporting information includes：D2D relay capabilities parameter, Uu
At least one in the parameter such as interface channel quality parameter and mobility parameters, certainly, also can wrap
Include other specification, present embodiment is not any limitation as to this.
For ensureing the standard of message, in implementing, described reporting information adopts RRC
Specific messages.
S202：Reporting information according to each UE determines the UE being suitable as relaying；
Reporting information according to each UE can determine that the UE being suitable as relaying, but in order to more
Accurately determine the UE being suitable as relaying, also contemplate base station in present embodiment current
State, notifies according on current network load, current radio resource utilization rate and each UE
Breath determines the UE being suitable as relaying.
S203：Send relay activation instruction to the described UE being suitable as relaying, so that receiving
UE to the instruction of described relay activation starts the pattern that relaying finds.
It will be appreciated that starting the pattern that relaying finds, enter according to Mode A or Mode B
Row relaying finds.
For ensureing the standard of message, in implementing, described relay activation instruction adopts
RRC connects reconfiguration message.
Present embodiment determined by the reporting information according to each UE be suitable as relay
UE, sends relay activation instruction to the described UE being suitable as relaying, so that receiving described
The UE of relay activation instruction starts the pattern that relaying finds, thus UE only can be receiving
Just start the pattern that relaying finds after stating relay activation instruction, decrease unnecessary UE energy
Consume, it is to avoid the problems such as resource contention and network interferences, simultaneously as relay activation instruction
Sent by base station, so base station can fully understand and controlling network in relaying UE quantity,
It is easy to management and the efficient utilization of Radio Resource.
Fig. 3 be one embodiment of the present invention D2D scene under relay UE Activiation method
Flow chart；With reference to Fig. 3, methods described includes：
S301：Receive the reporting information of each UE；
S302：Reporting information according to each UE determines the UE being suitable as relaying；
S303：Send relay activation instruction to the described UE being suitable as relaying, so that receiving
UE to the instruction of described relay activation starts the pattern that relaying finds；
Step S301～S303 is identical with the step S201～S203 of the embodiment shown in Fig. 2,
Will not be described here.
S304：Determine the UE being not suitable anymore for as relaying, be not suitable anymore for as relaying to described
UE send relaying deexcitation instruction so that receive described relaying deexcitation instruction UE
Stop the pattern that relaying finds.

RRC connects reconfiguration message.
The factors such as the network state due to UE can change in real time, so, last
As the UE of relaying, currently may be not suitable anymore for as relaying, for ease of making not
The UE being suitable as again relaying stops the pattern that relaying finds, present embodiment compares Fig. 2 institute
The embodiment showing, increased step S304.
With reference to Fig. 4, in step s 304, can be determined no longer suitable by following two modes
Cooperate the UE for relaying：
First kind of way is：The mode that base station determines is that is to say, that base station is according to current network
During the reporting information determination of load, current radio resource utilization rate and each UE is not suitable anymore for as
The UE continuing.
For example：The Uu interface channel quality parameter of UE is undesirable, or, the shifting of UE
Dynamic property parameter is undesirable, then this UE is the no longer suitable UE as relaying.
The second way is：The mode of UE request is that is to say, that the UE as relaying can
According to own situation, (UE as not having far-end in Preset Time connects or electricity is less than and presets
The factors such as electricity), send relaying deexcitation request to base station, base station receives in UE transmission
The deexcitation that continues is asked, and judges whether to permit according to current network load and current radio resource utilization rate
Permitted this UE not as relaying, if so, then using this UE as being not suitable anymore for as the UE that relays.
For ensureing the standard of message, in implementing, described relaying deexcitation request adopts
RRC specific messages.
Certainly, if base station does not allow this UE not as relaying, do not send instruction to this UE,
Or, the instruction not allowing deexcitation is sent to this UE.
For method embodiment, in order to be briefly described, therefore it is all expressed as a series of dynamic
Combine, but those skilled in the art should know, embodiment of the present invention is not retouched
The restriction of the sequence of movement stated, because according to embodiment of the present invention, some steps can adopt
Other sequentially or are simultaneously carried out.Secondly, those skilled in the art also should know, description
Described in embodiment belong to preferred implementation, involved action is not necessarily
Necessary to embodiment of the present invention.
