It is mapped on the corresponding dedicated bearer of specified QoS attributes, sends to core net.So as to carry out data service or
The mobile communication businesses such as voice call.
Fig. 5 is the dedicated bearer schematic diagram set up by wireless relay provided in an embodiment of the present invention, as shown in figure 5,
Radio repeater station UE initiates part QoS control flows, is specifically built by the QoS control module triggering of UE parts
Vertical radio repeater station and gateway (Serving GateWay, SGW)/PDN Gateway (Packet Data
Network GateWay, PGW) between dedicated bearer, the dedicated bearer set up by radio bearer and
S1 carries composition.
In due to prior art, eNB common to LTE increases Relay functions, realizes complexity, particularly to
In commercial LTE network, associated base stations are changed to support Relay functions, need edition upgrading, wireless tuning
Deng so that operation cost is significantly increased.The present invention is reduced to solve impact of the Relay deployment to existing network
Relay operation costs, there is provided above-mentioned wireless relaying technique scheme, need not upgrade to host base station, and
And multilevel relay and QoS controls can be realized.
Further, present invention also offers a kind of wireless relay system, the wireless relay system includes above-mentioned
Radio repeater station and host base station.Wherein, the ordinary base station that host base station has been disposed using existing network, wireless relay
Stand including radio repeater station UE parts and radio repeater station base station portion.Below in conjunction with Fig. 6-Figure 11 to this
It is bright to be further elaborated.
Fig. 6 is the wireless relay system network architecture diagram that the embodiment of the present invention 1 is provided, as shown in fig. 6, in nothing
Under line relay station is disposed using common core net with host base station, wherein SGW/PGW is deployed to a network element.
On radio repeater station after electricity, the cell of host base station, Ran Houwu are accessed in the UE parts of radio repeater station
QoS control flows are initiated in the UE parts of line relay station, complete the foundation of dedicated bearer.Radio repeater station UE
Partial QoS control module can be directed to the different data streams of radio repeater station base station portion and set up different special
Carry.Then the base station portion of radio repeater station passes through the base station data agent transmitting module and QoS of UE parts
Control module is mapped to base station data on specific QoS dedicated bearer and is transferred to core according to data flow QoS characteristic
Heart net, sets up S1 with MME and is connected, and finally completes the foundation of wireless relay cell, provides wireless service for UE.
Fig. 7 is the wireless relay system workflow diagram that the embodiment of the present invention 1 is provided, as shown in fig. 7, step
Including：
Step 201：Electricity on radio repeater station.
