Description
Technical field
The present invention relates to field of communication technology more particularly to a kind of downstream transmission Proxy Methods and agency based on DeNB
Device.
Background technique
Benefit is opened up in the network of the long evolving system (Long Term Evolution, LTE) of the current forth generation communication technology
In, in order to obtain better link capacity and wider array of coverage area, (Packet Transport usually is transmitted in grouping
Network, PTN) between equipment and user terminal (User Equipment, UE) dispose relay base station (Relay eNB,
ReNB), that is to say, that (be only illustrated), i.e., set in core net by taking down direction as an example when PTN device is communicated with UE
After preparation send downlink data message, when PTN device receives above-mentioned downlink data message, PTN device can be first by above-mentioned lower line number
It is sent to ReNB according to message, after ReNB performs corresponding processing above-mentioned downlink data message, then by ReNB will treated
Downlink data message is sent to corresponding UE.In this way, after being performed corresponding processing by ReNB to above-mentioned downlink data message, then
It is sent to corresponding UE, so that it may so that a second-rate link is converted into two preferable links of quality, cover to reach
The purpose that cover area is wide, transmission speed is fast.
It but in practical applications, is not directly visible between ReNB and PTN device, it will usually in ReNB and PTN
Wireless terminal accessing device (Customer Premise Equipment, CPE) and host base station are deployed between equipment
(Donor eNB, DeNB), wherein the LAN port of cpe device is connected by wired mode with ReNB, the WAN of cpe device
Port is wirelessly connected with DeNB.That is, (only following during actual PTN device and UE communication
It is illustrated for line direction), PTN device is when receiving the downlink data message of equipment of the core network transmission, first by lower line number
It is sent to DeNB according to message, then downlink data message is wirelessly sent to by WAN port by CPE by DeNB use and is set
It is standby, then, downlink data message is sent to by ReNB by LAN port by the way of wired by cpe device, finally, again by
Data message transmission is sent to corresponding UE by ReNB.
In the prior art, it to complete above-mentioned communication process, needs in advance in the transmission ginseng of PTN device side configuration ReNB
Number configures: VLAN ID (Virtual Local Area Network Identity, VLAN in PTN device side
ID), routing gateway and address resolution protocol (Address Resolution Protocal, ARP) list item, wherein ARP table
The IP address that the net association address (Internet Protocol, IP) of item is ReNB, media access control address (Media
Access Control, MAC) be DeNB MAC Address, and the ARP entry of ReNB needs to be added to PTN device side manually.In
In practical application, ReNB needs to borrow the configured transmission of DeNB, i.e. ReNB needs and the shared VLANID of DeNB, routing gateway, with
And ARP entry.
It (is only illustrated by taking down direction as an example) when PTN device sends downlink data message to UE, needs to first pass through
DeNB, then downlink data message is sent to by corresponding UE by ReNB, since ReNB needs to share VLAN ID with DeNB, and
And due to the limitation of PTN device upper port, need to guarantee that ReNB and DeNB belong to same network segment, PTN device could be smoothly by under
Row data message is sent to corresponding UE.Meanwhile in order to complete the switching of adjacent base station, need to establish between ReNB and DeNB
X2 link still establishes X2 link requirement ReNB and DeNB belongs to different segment, " needs to guarantee that ReNB and DeNB belongs to above-mentioned
In same network segment " it contradicts, in order to solve above-mentioned contradiction, a biggish network segment range can be configured for PTN device, and be
Cpe device configures a lesser network segment range, in this way, when PTN device thinks that ReNB and DeNB belong to same network segment, CPE
Equipment just will be considered that ReNB and DeNB belong to different segment, and still, this is ideal state, in practical applications, on
Contradiction is stated to still remain.
In practical applications, since ReNB needs to share equipment of the core network with DeNB, even if there are multiple cores net equipment,
But DeNB only preserves the IP address of an equipment of the core network, ReNB also must by uplink data messages by DeNB be sent to
On the corresponding equipment of the core network of IP address that DeNB is saved, uplink data messages are sent to core in DeNB in this way, just can guarantee
When heart net equipment, DeNB can find equipment of the core network corresponding with the IP address being locally stored, to complete uplink data messages
Smooth transmission.If uplink data messages are sent to the equipment of the core network for not saving IP address in DeNB by ReNB by DeNB
On, it will lead to DeNB when uplink data messages are sent to equipment of the core network, can not find corresponding equipment of the core network, that is, cause
Uplink data messages transmission failure.That is, even if there are multiple cores net equipment, if not saving above-mentioned multiple cores in DeNB
Uplink data messages can not be sent to above-mentioned multiple cores net equipment by DeNB by the IP address of heart net equipment, ReNB, this
It will lead to the waste of transfer resource.
In addition to this, the number of ReNB is more, and the ARP entry for needing to be added to PTN device manually is more, sets to PTN
Standby maintenance is more difficult, moreover, (i.e. PTN device reaches meeting after a certain period of time if aging occurs in the ARP entry of PTN device side
Delete ARP entry) when, then it is easy to appear transmit chain rupture, communication disruption.
