The base station of 3 different systems is connected with RN UE by wired IP networks.After RN UE is linked into DeNB, initiated the foundation of RN UE carrying by core net.Owing to supposing that above-mentioned wireless backhaul links is LTE link, therefore initiate carrying by LTE core network and set up.Multiple carrying can be set up according to the priority sending data different between RN UE and DeNB, the embodiment of the present invention, between RN UE and DeNB, set up RN can ensure bit rate (Guaranteed Bit Rate, being called for short GBR) carrying (bear) and RN do not ensure bit rate (None Guaranteed Bit Rate, abbreviation Non-GBR) bear.In specific implementation process, data higher for priority can be put in RN GBR bear and send, data lower for priority are put in RN Non-GBR bear and send, the transmission of high-priority data can be ensured.
But the embodiment of the present invention is not limited with the scene shown in Fig. 1.The standard that other are different can also be applied to, and different wireless backhaul networks.
Fig. 2 is the schematic flow sheet of the method for transmission processing embodiment two in wireless backhaul links provided by the invention, wireless backhaul links comprises transmission processing device and the first base station, the executive agent of the method is above-mentioned transmission processing device, and as shown in Figure 2, the method comprises:
S201, transmission processing device receive Internet Protocol (the Internet Protocol that the second base station sends, be called for short IP) bag, this IP comprises differentiated services code points (DifferentiatedServices Code Point the is called for short DSCP) value of the second base station encapsulates.
After the second base station receives the data (referring generally to business datum) of corresponding UE transmission, can IP be become to wrap the data transaction received, in transfer process, DSCP value is all encapsulated in IP bag, generally, DSCP value is arranged in first 6 of COS (Type of Service the is called for short TOS) field of IP bag.The IP changed bag is sent to RN UE by each second base station afterwards.
S202, transmission processing device identify according to the DSCP value in above-mentioned IP bag the priority that this IP wraps.
After RN UE receives IP bag, obtain the DSCP value in IP bag, identify according to DSCP value the priority that this IP wraps.Particularly, RN UE can identify according to the corresponding relation of DSCP value and priority the priority that this IP wraps.
IP bag, according to the priority of above-mentioned IP bag, is mapped in carrying corresponding to priority by S203, transmission processing device.
Can be specifically that the IP of high priority bag is mapped in GBR bear, the IP of low priority bag is mapped in Non-GBR bear.The data ensured on GBR bear can be paid the utmost attention to during DeNB scheduling, the high data of priority so just can be made to be preempted.IP bag can be distributed to the equipment of the core network of corresponding standard by DeNB.Wherein, GBR bear can be aforementioned RN GBR bear, Non-GBRbear can be aforementioned RN Non-GBR bear.
S204, transmission processing device send above-mentioned IP bag by the carrying that above-mentioned priority is corresponding to the first base station.
In specific implementation process, the IP bag that above-mentioned transmission processing device receives the second base station transmission can be specially the IP bag that transmission processing device receives the second base station transmission of multiple different systems.With reference to Fig. 1, this second base station can be the LTE eNB in Fig. 1, and WI-FI AP, UMTS Node, RN UE can receive LTE eNB simultaneously, the IP bag that WI-FI AP, UMTS Node sends.DSCP value is loaded onto in the IP encapsulating that these second base stations can be respectively their transmissions.
It should be noted that, the wireless access network of different systems, the priority of empty port load-supporting divides different, for kind of the standard of 3 shown in Fig. 1:
(1) for LTE system, according to third generation partner program (The3rd GenerationPartnership Project, be called for short 3GPP) proposal, by in LTE system, the demand of the data of transmission to packet loss and time delay is divided in order to 9 types, identify by the value 1 ~ 9 of the mark (QoS ClassIdentifier is called for short QCI) of QoS classification respectively, different QCI corresponds to different empty port load-supportings, as shown in table 1, the business datum of LTE is classified according to QCI value:
Table 1
| QCI | Priority | Delay requirement | Packet loss | Business is illustrated |
| 1 | 2 | 100ms | 10 -2 | Real-time voice |
| 2 | 4 | 150ms | 10 -3 | Real-time video (Streaming Media) |
| 3 | 3 | 50ms | 10 -3 | Real-time game |
| 4 | 5 | 300ms | 10 -6 | Non-real-time video (available buffer broadcasting) |
| 5 | 1 | 100ms | 10 -7 | IMS signaling |
| 6 | 6 | 300ms | 10 -8 | Www. pp file transmission, chat, mail |
| 7 | 7 | 100ms | 10 -3 | Interactive game, field speech video is reported |
| 8 | 8 | 300ms | 10 -6 | Www. pp file transmission, chat, mail |
| 9 | 9 | - | - | - |
Note: in table 1, IMS is IP multimedia system (IP Multimedia Subsystem is called for short IMS).
As can be seen from Table 1, QCI value has been the business datum correspondence of 1 ~ 5 compared with the business of high real-time low packet loss ratio, and these service priority are higher.Relative, QCI value be 6 ~ 9 business datum priority lower.
Further, being worth arranging for DSCP in LTE base station can with reference to related protocol (such as: comment demand file (Request For Comments, be called for short RFC) 2597, RFC2598) suggestion, for table 2, for the DSCP value of different Q CI value corresponding data can be as follows:
Table 2
| QCI | DSCP | PHB | Bearer types |
| 1 | 0x2E | EF | GBR |
| 2 | 0x1A | AF31 | GBR |
| 3 | 0x22 | AF41 | GBR |
| 4 | 0x1A | AF31 | GBR |
| 5 | 0x2E | EF | GBR |
| 6 | 0x12 | AF21 | Non-GBR |
| 7 | 0x12 | AF21 | Non-GBR |
| 8 | 0x0A | AF11 | Non-GBR |
| 9 | 0x0 | BE | Non-GBR |
Note: in the present embodiment, PHB is the process behavior (Per HopBehavior be called for short PHB) of IP bag through each router.
Can find out, the IP that the QCI value of DSCP value correspondence can be 1 ~ 5 by RN UE wraps and is mapped in RN GBR bear, transmits.The IP being 6 ~ 9 by the QCI value of DSCP value correspondence wraps and is mapped on RN Non-GBR bear, transmits.
Self-defined different DSCP value can certainly carry out corresponding different QCI value, not be defined as limit with above-mentioned.
(2) for UMTS system, user service data is divided into interactive, dataflow-style, interactive, rear bench-type, interactive data priority is the highest, therefore by interactive data-mapping on RN GBRear, other data-mapping is on RN Non-GBR bear.Being worth arranging for DSCP in UMTS base station can with reference to the suggestion of related protocol (such as: RFC2597, RFC2598), and for table 3, the DSCP value of different service types corresponding data can be as follows:
Table 3
| The UMTS grade of service | Diff-Serv PHB | DSCP | Bearer types |
| Interactive | EF | 0x2E | GBR |
| Dataflow-style | AF11，AF12，AF13 | 0x12 | Non-GBR |
| Interactive | AF21，AF22，AF23 | 0x0A | Non-GBR |
| Rear bench-type | Best Effort | 0 | Non-GBR |
Self-defined different DSCP value can certainly carry out corresponding dissimilar data, not be defined as limit with above-mentioned.
(3) in wlan system, because WI-FI is usually used as a kind of comparatively cheap communication mode, the business of LTE and UMTS is supplemented, thus relative to the business of LTE and UMTS, WI-FI business datum priority is lower, can allowing WI-FI AP, when converting data to IP bag, DSCP value is all set to 0, after receiving the IP bag of WI-FI AP transmission, being all mapped to RNNon-GBR bear to make RN UE and transmitting.For table 4, DSCP value corresponding to WI-FI business datum is as follows:
Table 4
| Business datum | Diff-Serv PHB | DSCP | Bearer types |
| WI-FI | BE | 0 | Non-GBR |
Self-defined different DSCP value can certainly carry out corresponding WI-FI business datum, not be defined as limit with above-mentioned.
