Embodiment
The method of detection peer node route configuration state of the present invention provides the technical scheme of a kind of automatic detection opposite end route configuration state, below in conjunction with accompanying drawing this method is further described, the node that will connect two ends in following declarative procedure is defined as this end node and peer node respectively, wherein, arbitrary end all can be used as this end node, at this moment, the other end is then as peer node.
The method of detection peer node route configuration state provided by the invention mainly comprises following each step:
At first, need Status Flag be set at the path that disposes on this end node, whether Status Flag is used to indicate described path and disposes on peer node, when described Status Flag indicates for disposing, disposed this path on the expression peer node, when described Status Flag indicates for not disposing, do not dispose this path on the expression peer node;
Described Status Flag can adopt effective marker position " 1 " and invalid flag position " 0 " to represent respectively, wherein with effective marker position " 1 " as disposing sign, disposed this path on the expression peer node, as not disposing sign, do not dispose this path on the expression peer node with invalid flag position " 0 ";
Certainly, also can adopt other corresponding marker bit as the sign of configuration of described Status Flag and configuration sign.
After being provided with above-mentioned Status Flag at each path, the renewal that also needs to carry out this Status Flag according to information mutual between this end node and peer node is handled;
For example, can at first send reset path message to the opposite end, the acknowledge message that resets that whether responds on this path by the detection opposite end judges whether the opposite end has disposed this path then, and described renewal processing procedure further may further comprise the steps as shown in Figure 3:
Step 31: the Status Flag of determining the path that disposes on this end node is during for configuration sign not, then sends reset path message in the AAL2 signaling protocol to peer node;
Described Status Flag comprises for the situation that does not dispose sign:
When local terminal has disposed a paths, defaultly think not configuration of opposite end, its Status Flag is set to not dispose sign;
When local terminal sends the message that connects when overtime, the Status Flag in the applied path that then connects is set to not dispose sign;
When local terminal transmission reset path message was overtime, then the Status Flag of respective paths was set to not dispose sign;
Step 32: after peer node is received described reset path message, check whether disposed this path, if disposed, then execution in step 34, return the acknowledge message that resets to this end node, and the Status Flag in local this path is set to dispose sign, represent that this path is configured on other end node (being described end node), this path is used at two ends when any end all can be in the connection of initiating to set up between two ends like this, carry out 35 afterwards, otherwise execution in step 33 abandons this message;
Step 35: after this end node was received the acknowledge message of returning the opposite end that resets, the Status Flag in described path was set to dispose sign.
In addition, if this end node receive the opposite end to reset path message, the block message in this path, separate and close message or the message that connects on this path, illustrate that then this path disposes in the opposite end, this moment, the Status Flag in this path on promptly can this end node was set to dispose sign.
If the opposite end does not dispose this path, then the Status Flag in this path of this end node still is configuration sign not, and this end node can continue to detect after postponing a period of time, promptly restarts execution in step 31, disposes this path up to the opposite end.
Simultaneously, after the opposite end disposed this path, in normal application process, the opposite end also may be owing to other reason causes this path deletion or unavailable; At this moment, if local terminal is overtime or reset path message is overtime in the transmission message that connects, the Status Flag that this path also can be set is configuration sign not, restarts execution in step 31 then, handles with the renewal of carrying out Status Flag.
Above-mentioned Status Flag renewal process steps 31 to step 35 can also have been adopted following process and substituted:
On the basis of AAL2 signaling protocol, increase path query message, message bearing the information in the path that local terminal need detect, after described path query message is received in the opposite end, whether inquiry this locality exists this path, and Query Result returned to this end node, simultaneously, if Query Result shows local this path that exists, then also need be set to dispose sign at the Status Flag in this path, this locality, expression is local initiate to set up with described local terminal between be connected the time can use this path;
After this end node is received the Query Result that peer node returns, upgrade the Status Flag in this path according to Query Result, obviously: do not have this path if Query Result is the opposite end, then the Status Flag in this path still indicates for not disposing in this end node, have this path if Query Result is the opposite end, then this end node needs the Status Flag in this path to be set to dispose sign.
Upgrade processing procedure for further improving the Status Flag that relates among the present invention, also comprise: used the not configuration of a path local terminal if find the opposite end, can also be initiatively to opposite end transmit path state notifying, there is not this path in the notice local terminal, like this, the opposite end can not dispose sign with the Status Flag setting in this path after receiving described path status notice.
The present invention also provides the method that connects between a kind of node based on the AAL2 signaling protocol based on said method, this method comprises: when asking to connect between two nodes based on the AAL2 signaling protocol, the node of then initiating to connect need judge that whether the Status Flag in the path of being adopted of connecting is for disposing sign, if, then use this path to connect, otherwise, do not use this path to connect.Like this, just, can avoid effectively because the inconsistent procedure failure that connects that causes of routing information that two end nodes are preserved.Improved the quality of communication service.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claims.
