Description
Technical field
The present invention relates to the network communications technology field, be specifically related to the method that a kind of data transmit.
Background technology
WiMAX is an emerging technology.WiMAX can provide " last kilometer " broadband connection in the territorial scope more wide than Wi-Fi.WiMAX has two technical standards now: IEEE 802.16d and IEEE 802.16e, and wherein, 802.16d has only defined two kinds of network elements, and promptly BS and SS adopt the interconnection of broadband fixed wireless access technology between BS and SS; 802.16e also only defined two kinds of network elements, promptly BS and MS adopt broadband mobile wireless access technology interconnection between BS and MS.
WiMAX Forum has defined ASN and CSN on 802.16 basis, form broadband WiMAX network, with support to fix, nomadic, portable, simple IP moves or move entirely and insert.The overall frame of reference of WiMAX network as shown in Figure 1.
Among Fig. 1, R1 is the reference point between MS/SS and ASN, and R3 is the reference point between ASN and CSN.
ASN in the WiMAX network can resolve into: the several functional entitys of BS (base station), DP (Decision point, decision point) and EP (Excution point carries out point), the reference point between BS and EP is R6.Annexation between BS, DP, EP and the CSN can be for shown in the accompanying drawing 2.
Among Fig. 2, solid line is represented the connection of carrying aspect, and dotted line is represented to control, the connection of management layer.
In the basic networking of WiMAX, the protocol hierarchy between the MSS-ASN-CSN as shown in Figure 3.
Among Fig. 3, ASN-GW is the combination of ASN-EP and ASN-DP, is ASNbackhaul (ASN bearer network) between BS and the ASN-GW.
R6tunnel is the connection tunnel between BS and the ASN-EP, this tunnel can be realized by concrete tunneling technique such as 802.1Q VLANS, MPLS tunnels (multi-label protocol switching tunnel) or GRE (generic routing encapsulation, generic route encapsulation).
At present, can set up R6 tunnel:1, set up R6 tunnel by three kinds of modes according to the granularity of R6 tunnel according to stream; 2, set up R6 tunnel according to MSS/SS; 3, set up R6 tunnel according to BS.
When setting up R6 tunnel according to stream, the corresponding specific stream of having classified of each R6 tunnel is as traffic stream identifier such as CID or the SFID etc. of corresponding one 802.16 of each R6 tunnel.The classification work of stream can only be carried out once in the ASN network, and the concrete operations of later convection current are directly carried out index according to R6 tunnel and got final product.
This method can make each Business Stream directly correspond on the R6 tunnel, but, set up R6 tunnel according to stream and can cause having a large amount of tunnels between BS and the ASN-EP, thereby increased the burden that ASN Backhaul between BS and the EP safeguards these tunnels greatly.Because BS and EP are the interconnection of multi-to-multi, R6 tunneltag should be unique in a BS or ASN-EP, and an ASN-EP may connect a plurality of BS, what can cause like this that the R6 tunnel quantity on the ASN-EP can be very is big, finally surpasses the quantity that R6 tunnel tag can represent.When MSS switched, so a large amount of tunnels needed to remove, set up, and can run into very big problem aspect the performance of equipment and the switching efficiency.
When setting up R6 tunnel according to MSS/SS or BS, because the granularity of R6 tunnel is thicker, can only distinguishes the roughly path of ASN inside, thereby significantly reduce R6 tunnel tunnel, simplified the burden that ASN backhaul safeguards these tunnels.Because the minimizing of tunnel quantity, when MSS switched, efficient can be significantly increased.But, if desired according to the QoS in the traffic classification realization ASN, must realize corresponding traffic classification work respectively at BS and ASN-EP the inside, then, carry out the QoS operation again.In ASN, repeat identical traffic classification work, can reduce the operating efficiency of functional entity in the ASN greatly.

Based on core concept of the present invention technical scheme provided by the invention is further described below.
The present invention at first needs to set up tunnel between BS and the EP according to wireless terminal such as MSS, SS.After setting up good above-mentioned tunnel, between BS and the EP when transmitting data mutually by above-mentioned tunnel, need be with the traffic classification identification information of data notice opposite end, make the opposite end can be directly determine the data of its reception are carried out the flow operation of a series of and path independence such as corresponding gate, QoS according to the traffic classification identification information of notice.Because BS is only relevant with the quantity of wireless terminal with the tunnel quantity between the EP among the present invention, so, the present invention can be when reducing tunnel quantity between BS and the EP, alleviating ASN backhaul (ASN bearer network) and safeguard the tunnel burden, improve the wireless terminal switching efficiency, avoid the traffic classification work that functional entity repeats in the ASN, improved the operating efficiency of functional entity in the ASN greatly.
The tunnel that the present invention sets up between BS and EP can be for the individual layer tunnel, also can be double layer tunnel.
When the tunnel between BS and the EP is the individual layer tunnel, for make things convenient for through street that data between the BS-EP-CSN transmit by, the tunnel identification information between this individual layer tunnel identification information and EP and the CSN is provided with corresponding relation.Like this, when EP receives the data that CSN sends by the tunnel between itself and the CSN, can index tunnel identification information between corresponding EP and the BS according to this tunnel identification information, realize through street that the ASN internal data transmits by.When the tunnel identification information of EP between EP that indexes according to it and BS transmits data, also need to produce the traffic classification identification information of these data, and this traffic classification identification information and data are sent to BS by corresponding tunnel together.At this moment, BS does not need to carry out traffic classification work again, directly according to the traffic classification identification information of its reception data is carried out a series of flow operation with path independence such as corresponding gate, QoS, then, its these data is continued to transmit, as be sent to wireless terminal etc.When the data that the data such as the wireless terminal of its reception need be sent as BS are sent to EP, determine the EP of this data correspondence and the tunnel identification information between the BS, simultaneously, produce the traffic classification identification information of these data, and this traffic classification identification information and data are sent to EP by corresponding tunnel together.EP does not need to carry out traffic classification work again, directly data are carried out a series of flow operation with path independence such as corresponding gate, QoS according to the traffic classification identification information of its reception, and, EP can index tunnel identification information between corresponding EP and the CSN according to its tunnel identification information that receives data, realize through street that the ASN data transmit by.Internal layer tunnel identification information in the double layer tunnel that the traffic classification identification information here is equivalent to describe below.
When the tunnel between BS and the EP was double layer tunnel, outer layer tunnel of the present invention can be called R6OUTER TUNNEL (R6 outer layer tunnel), and outer layer tunnel is mainly used in the sign path, therefore, when setting up outer layer tunnel, the main employing principle relevant with the path.The path here is meant the path of BS-EP-CSN.In ASN, the path one-to-one relationship as shown in Figure 4 between the transmission of the data of outer layer tunnel of the present invention and ASN and the CSN.
In Fig. 4, the path of BS-EP-CSN represents that with PATH this path mainly is made up of the MIP TUNNEL between R6OUTER TUNNEL and the EP-CSN (mobile IP tunnel) between the BS-EP, and R6OUTER TUNNEL is corresponding one by one with path P ATH.The foundation of PATH can be responsible for by DP, i.e. the foundation of R6OUTER TUNNEL and MIP TUNNEL is responsible for by DP.EP can carry out the quick exchange of R6 ball OUTER TUNNEL and MIP TUNNEL by R6 OUTERTUNNEL ID.Like this, by outer layer tunnel of the present invention, can realize that the fast path of ASN inside is searched.
Internal layer of the present invention tunnel can be called R6 INNER TUNNEL (R6 internal layer tunnel), and the internal layer tunnel is mainly used in sign stream.R6 INNER TUNNEL is corresponding with stream fully, and promptly R6 INNER TUNNELID (R6 internal layer tunnel identification information) is corresponding one by one with flow identification information.EP can be a series of by R6 INNERTUNNEL ID convection current carrying out gate, QoS etc. and the flow operation of path independence.
At up direction, promptly in BS to EP direction, produce R6INNER TUNNEL ID by BS for its data that need be sent to CSN, BS is sent to EP by corresponding R6 OUTER TUNNEL, R6 INNER TUNNEL with data, EP determines that it receives the R6 INNER TUNNEL ID of data, and directly uses this R6 INNER TUNNEL corresponding flow identification information of ID index such as SFID etc.EP directly carries out corresponding flow operation according to its flow identification information that indexes, and simultaneously, EP determines that it receives the R6 OUTERTUNNEL ID of data, and determines the MIP TUNNEL of this R6 OUTER TUNNEL ID correspondence.EP is sent to CSN according to its MIP TUNNEL that determines with data.Thereby, data for BS to EP direction transmit, the present invention can be under the prerequisite of guaranteed qos, utilize R6 INNER TUNNEL ID to make the functional entity in the ASN only carry out a traffic classification job, as only needing BS to carry out a traffic classification job, the traffic classification work of having avoided EP to carry out has improved the operating efficiency of EP, and, realized the quick exchange of R6 OUTER TUNNEL and MIP TUNNEL.
At down direction, promptly in EP to BS direction, EP receives CSN data that send, that need be sent to BS by the MIP TUNNEL between itself and the CSN, produce corresponding R6 INNER TUNNEL ID by EP for data its reception, that need be sent to BS, simultaneously, EP determines that it receives the MIPTUNNEL of data, and the R6 OUTER TUNNEL ID of definite this MIP TUNEL correspondence, EP is sent to BS with data by corresponding double layer tunnel according to R6OUTER TUNNEL ID, R6 INNER TUNNEL ID.BS determines that it receives the R6 INNER TUNNEL ID of data, and directly uses this corresponding flow identification information of R6 INNERTUNNEL ID index such as SFID etc.BS directly carries out corresponding flow operation according to its flow identification information that indexes.Thereby, data for EP to BS direction transmit, the present invention can be under the prerequisite of guaranteed qos, utilize R6 INNER TUNNEL ID to make the functional entity in the ASN only carry out a traffic classification job, as only needing EP to carry out a traffic classification job, the traffic classification work of having avoided BS to carry out has improved the operating efficiency of BS, and, realized the quick exchange of R6 OUTER TUNNEL and MIP TUNNEL.
The inside and outside layer of R6 tunnel data on ASN backhaul transmit schematic diagram as shown in Figure 5.
Among Fig. 5, for ASN with double layer tunnel exchange capacity, R6 INNER TUNNEL can be invisible to the ASN Backhaul between BS and the ASN-GW, ASN Backhaul only handles R6 OUTERTUNNEL, so the present invention can change to existing ASN Backhaul.Therefore, the tunnel quantity beguine that need safeguard processing of the ASN Backhaul among the present invention sets up according to stream that institute's tunnel to be processed quantity significantly reduces in the R6 tunnel scheme.
The corresponding relation of the traffic classification identification information on R6 INNER TUNNEL ID and the BS can be the mapping of R6INNER TUNNEL ID and SFID, like this, carry out flow operation at ASN internal condition R6 INNER TUNNELID, can guarantee inner flow operation relevant of ASN such as the consistency of QoS with air interface.
Tunnel identification information such as individual layer tunnel identification information, internal layer tunnel identification information among the present invention, the outer layer tunnel identification information can be by ASN-DP unified management and distribution.When ASN Backhaul does not have the tunnel exchange capacity, when promptly not supporting TUNNEL ID function of exchange, DP should guarantee to share tunnel identification information among each BS of an EP unique, do not overlap mutually, promptly when the tunnel between EP and the BS is the individual layer tunnel, tunnel identification information among each BS of a shared EP does not overlap mutually, when the tunnel between EP and the BS was double layer tunnel, the outer layer tunnel identification information among each BS of a shared EP did not overlap mutually; When ASN Backhaul has the tunnel exchange capacity, when promptly supporting TUNNEL ID function of exchange, tunnel identification information among each BS of a shared EP can overlap mutually, promptly when the tunnel between EP and the BS is the individual layer tunnel, tunnel identification information among each BS of a shared EP can overlap mutually, when the tunnel between EP and the BS was double layer tunnel, the outer layer tunnel identification information among each BS of a shared EP can overlap mutually; At this moment, ASN-DP is distribution T UNNEL ID more easily, be that DP can be only be configured the exchange of the tunnel identification information of ASN bearer network, tunnel identification information among EP, the BS can oneself be distributed by it, just can well guarantee the R6 OUTER TUNNEL ID uniqueness on BS and ASN-EP respectively, thereby greatly reduce the work complexity that DP sets up the tunnel between BS and the EP.
Outer layer tunnel of the present invention, internal layer tunnel can adopt existing tunneling technique to realize, as 802.1QVLAN, MPLS, GRE etc.Inside and outside layer of the present invention tunnel has independence, and promptly inside and outside layer tunnel can adopt identical tunneling technique to realize, also can adopt different tunneling techniques to realize.
