Specific embodiment
A possibility that in order to solve larger user data package propagation delay time existing in the prior art, user data packet loss It is higher, alternatively, the problem of core net is paralysed, in the embodiment of the present invention, by according to the type information for obtaining tunnel to be established come The tunnel between core network user face node and auxiliary access network node is established, establishes in mode and switches in different tunnels, It avoids when congestion occurs in the backbone network between auxiliary access network node and main access network node, auxiliary access network node and core net Tunnel between user face nodes continues through main access network node and transfers, in this way, just reduce auxiliary access network node and The congestion of backbone network between main access network node reduces user data package propagation delay time, and reduces user data package and lose It loses, alternatively, avoiding when the path hand off signaling that core network control surface node needs to receive and dispatch is excessive, auxiliary access network node and core Tunnel between the node of heart network users face is direct-connected tunnel, in this way, avoiding what core network control surface node needed to receive and dispatch Path hand off signaling excessively caused by core net paralysis.
The preferred embodiment of the present invention is described in detail with reference to the accompanying drawing.
As shown in fig.2, the detailed process that tunnel is established is as follows in the embodiment of the present invention:
Embodiment one:
Step 200: receiving the first tunnel that core network control surface node is sent and establish request, wherein the first tunnel is established Request is that core network control surface node is sent after request is established in the second tunnel for receiving the transmission of core network user face node；
Step 210: obtaining the type information in tunnel to be established；
Step 220: being established and requested according to the first tunnel, based on the type information in tunnel to be established, establish core network user Tunnel between face node and auxiliary access network node.
In the embodiment of the present invention, the content carried in request and the foundation request of the second tunnel is established in the first tunnel can be identical It can also be different.
In the embodiment of the present invention, in step 200, triggering core network control surface node sends the first tunnel and establishes request There are many conditions, for example, it may be when core network user face node determines that terminal will carry out service interaction with core net, core Network users face node sends the second tunnel to core network control surface node and establishes request, and then, core network control surface node is connecing It after receiving the foundation request of the second tunnel, sends the first tunnel and establishes request, also want other modes, no longer carry out herein detailed one by one It states.
In the embodiment of the present invention, there are many modes that obtain the type information in tunnel to be established:
For example, then first receive tunnel type instruction message parses tunnel to be established from tunnel type instruction message Type information, wherein tunnel type instruction message can be OAM (Operation Administration and Maintenance, Operations,Administration And Maintenance) system transmission, it is also possible to the transmission of core network user face node, can also be What core network control surface node was sent.
OAM is when perhaps core network user face node or core network control surface node send tunnel type instruction message, The type information in tunnel to be established can be determined according to network load information, and then, the type in determining tunnel to be established is believed Then breath addition, is sent in tunnel type instruction message.
From this mode of type information for parsing tunnel to be established in tunnel type instruction message, tunnel is received Type instruction message can be before request is established in the first tunnel for receiving core network control surface node transmission, be also possible to After request is established in the first tunnel for receiving core network control surface node transmission.
In another example establishing in request the class for parsing tunnel to be established from the first tunnel that core network control surface node is sent Type information, wherein tunnel type information is that core network user face node or core network control surface node are believed according to network load Breath determination.
Under this kind of mode, asked since core network user face node sends the foundation of the second tunnel to core network control surface node After asking, core network control surface node just sends the first tunnel and establishes request, therefore, can be in core network user face node to core When heart network control surface node sends the foundation request of the second tunnel, the type information addition in tunnel to be established is established in the second tunnel In request, core network control surface node adds the type information in tunnel to be established after receiving the second tunnel and establishing in request It is established in request in the first tunnel；It is also possible to the type information that tunnel not established in request is established in the second tunnel, core Network control surface node establishes the type information addition in tunnel to be established in the first tunnel when sending the foundation request of the first tunnel In request.
Further for example, obtaining network load information, and the type information in tunnel to be established is determined according to network load information.
In above-mentioned several ways, either which node is come the network load information determined, and network load information is all It may include: the data load that tunnel has been established between auxiliary access network node and main access network node, core network control surface node One of path hand off signaling load or any combination.
In above process, when it is non-establish tunnel for the first time when, it is negative according to network that tunnel type information is only determining main body What lotus information determined, when establishing tunnel for the first time, due to generating network load information not yet, determining main body can be according to fortune Battalion quotient's is pre-configured with determining tunnel type information.
In the embodiment of the present invention, the executing subject of step 200-220 will also be to the determination of the type information in tunnel to be established Main body sends the capability indication message for carrying the tunnel type information supported, then, it is determined that the type information in tunnel to be established Main body just can be according to the tunnel type information of support and the type information for being pre-configured with determining tunnel to be established of operator.
For example, referring to if the type information in tunnel to be established is obtained from tunnel type instruction message receiving tunnel type Before showing message, to OAM system, perhaps core network user face node or core network control surface node send what carrying was supported The capability indication message of tunnel type information；
If establishing the type information in request tunnel to be established according to the first tunnel, request is established receiving the first tunnel Before, the ability for carrying the tunnel type information supported is sent to core network user face node or core network control surface node Instruction message.
For example, can be OAM transmission with tunnel type instruction message, accessed based on the executing subject of step 200-220 It is illustrated for net node.Main access network node after powering, the ability for carrying the tunnel type information supported is sent to OAM Instruction message, then, OAM send to main access network node and are pre-configured with determining tunnel type information, according to operator During subsequent, OAM is likely to determine the type information in tunnel to be established according to network load information, and then will be according to network Information on load determines the type information in tunnel to be established, and carrying is sent in tunnel type instruction message.
Wherein, when obtaining network load, it can be and actively carry out detection acquisition, be also possible to receive other nodes hair Come, for example, the data load in tunnel has been established between the auxiliary access network node and main access network node that obtain can be, when auxiliary The data load (for example, user data traffic) that tunnel has been established between access network node and main access network node reaches first in advance After gating limit value, auxiliary access network node or main access network node actively report the data load, are also possible to periodicity It checks the data load that tunnel has been established between auxiliary access network node and main access network node, and then obtains the data load.
For example, the path hand off signaling load of the core network control surface node obtained can be, when core network control surface section After the path hand off signaling load of point reaches the first predetermined threshold value, core network control surface node is actively by path hand off signaling Load reports, and is also possible to periodically check the path hand off signaling load of core network control surface node, and then obtain the path Hand off signaling load.
For example, the network load that OAM is obtained, can determine auxiliary access network node and main access net section in auxiliary access network node When the data load in tunnel having been established between point more than the first predetermined threshold value, auxiliary access network node reports to the network load OAM。
In the embodiment of the present invention, the type information in tunnel to be established can be it is a variety of, for example, it may be being accessed supplemented by allowing Net node terminate from the tunnel of core network user face node, alternatively, can be forbid supplemented by access network node termination come from In the tunnel of core network user face node.
In the embodiment of the present invention, the mode in the tunnel established between core network user face node and auxiliary access network node has more Kind, for example, establish the first tunnel between core network user face node and main access network node, and establish auxiliary access network node and The second tunnel between main access network node；For example, establishing the third between core network user face node and auxiliary access network node Tunnel.
In the embodiment of the present invention, the mode in the first tunnel between core network user face node and main access network node is established There are many, optionally, the endpoint of a tunnel that obtains core network user face node distribute is established in request from the first tunnel received Corresponding first tunnel information, and corresponding second tunnel information of endpoint of a tunnel that main access network node distributes is sent to core Network users face node, wherein if the executing subject of step 200-220 is main access network node, according to aforesaid operations, if step The executing subject of rapid 200-220 is not main access network node, then establishes in request from the first tunnel received and obtain core net After corresponding first tunnel information of endpoint of a tunnel of user face nodes distribution, first tunnel information is also sent to main access Net node.
Similarly, in the embodiment of the present invention, the side in the second tunnel between auxiliary access network node and main access network node is established There are many formulas, optionally, the corresponding third tunnel information of endpoint of a tunnel that main access network node distributes is sent to auxiliary access net Node；Receive corresponding 4th tunnel information of endpoint of a tunnel of auxiliary access network node distribution, wherein if step 200-220's holds Row main body is main access network node, according to aforesaid operations, if the executing subject of step 200-220 is not main access net section Point, then after receiving corresponding 4th tunnel information of endpoint of a tunnel that auxiliary access network node distributes, also by the 4th tunnel information It is sent to main access network node.
