Description
Technical field
The present invention relates to the communications field, and in particular to a kind of communication means based on relay request and
Device.
Background technology
In the 3GPP R13 of Long Term Evolution (Long Term Evolution, LTE) network system
In, the concept of relay UE is introduced, relay UE are represented can be used as the terminal of relaying, and it is not
Only it is a common terminal, is also used as the relaying section of remote terminal (remote UE)
Point so that the remote UE for being in (out of coverage) outside network coverage also can
By the evolved base station (eNB) in the relay forwarding function access network of relay UE.
Communicated using the communication resource of D2D between remote UE and relay UE, relay
UE necessarily be in network coverage (in coverage), and remain RRC
CONNECTED states, such eNB could control the relay role of relay UE the moment.
When eNB in LTE network is that network node distributes resource pool, it is divided into two kinds：Communication money
Source pond and relay resource pools.Resource pool is that the periodicity time-frequency domain used in D2D communication process is provided
Source block, after the resource pool is handed down to UE, UE can just make to be wrapped in resource pool description
The communication resource block for containing is communicated.Communication resource pond is the communication authority that eNB distributes to UE,
It is the periodic location set of the communication resource that the UE is allowed to occupancy；Relay resource pools are eNB
Distribute to the forwarding authority of via node so that UE possesses data forwarding function.Wherein, UE
Represent terminal, such as mobile phone, flat board terminal device.
When relay UE will be communicated, will be by ProseUEInformation to eNB
The proprietary relay resource pools of request, eNB is indicated using a characterization parameter (value tag)
Whether the resource pool for being allocated to relay UE can be used for relay.If it is then this resource
Pond can be used for relay.If it is not, then current relay UE need to abandon relay functions, and by
Other terminals realize data forwarding function as relaying.
The content of the invention
Due to existing in current communication when the resource pool that eNB is sent to relay UE cannot be used for
During relaying, relay UE need to abandon the problem of relay functions, and the present invention proposes a kind of based on relaying
The communication means and device of request.
In a first aspect, the present invention proposes a kind of communication means based on relay request, including：
When evolved base station eNB is sent to the resource pool instruction of relaying relay UE for communication is provided
When source pond instructs,
The relay UE send relaying relay and ask to the eNB；
The eNB is asked according to the relay, and relay resources are sent to the relay UE
Pond instructs；
The relay UE receive the relay resource pools instruction, obtain relay resource pools, and
Data forwarding is carried out as via node；
Wherein, relay UE represent can as relaying terminal.
Preferably,
The relay UE send relaying relay and ask to the eNB, including：
The relay UE receive the resource pool instruction, and send pressure relay to the eNB
Request.
Preferably,
The eNB is asked according to the relay, and relay resources are sent to the relay UE
Pond instructs, including：
The eNB is asked according to the pressure relay, changes the value of characterization parameter, and will bag
Relay resource pools instruction containing amended characterization parameter is sent to the relay UE.
Preferably, the relay UE send relaying relay and ask to the eNB, including：
By after Preset Time, the relay UE send relay and ask to the eNB.
Second aspect, the present invention also proposes a kind of communicator based on relay request, including：
Relay request module, for being sent to link terminal relay UE as evolved base station eNB
Resource pool instruction for communication resource pond instruct when, by relaying relay UE to evolved base station
ENB sends relaying relay requests；Wherein, relay UE represent can as relaying terminal；
Resource pool sending module, for being asked according to the relay by the eNB, to institute
State relay UE and send the instruction of relay resource pools；
Trunk module, instructs for receiving the relay resource pools by the relay UE,
Relay resource pools are obtained, and data forwarding is carried out as via node.
Preferably, the relay request module is used to receive the resource by the relay UE
Pond instructs, and sends pressure relay requests to the eNB.
Preferably,
The resource pool sending module is used for please according to the pressure relay by the eNB
Ask, change the value of characterization parameter, and by the relay resource pools comprising amended characterization parameter
Instruction is sent to the relay UE.
Preferably, the relay request module is used for by after Preset Time, by the relay
UE sends relay and asks to the eNB.
As shown from the above technical solution, pressure relay request is sent or by default by eNB
Relay request is sent to eNB so that the current node in network coverage can after time
Carry out data forwarding as via node, without expend extra Internet resources look for other expire
The via node of sufficient condition, improves network performance.
