Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in qualification the present invention.
Fig. 2 shows the flow chart according to the raising method of the M3UA signalling route reliability of the embodiment of the invention.As shown in Figure 2, it may further comprise the steps: S202, activate application server, test lead finds and the corresponding routed keyword of application server by routing context, and the STATUS ENQUIRY message that periodically will have a point coding in the routed keyword sends to tested end; S204, tested end is received STATUS ENQUIRY message, whether the point coding of more tested end is consistent with the point coding in the STATUS ENQUIRY message, and the response that will comprise comparative result sends to test lead; And S206, test lead is received response, and handles application server process under the application server according to comparative result.
In the method, if the point coding of tested end is consistent with the point coding in the STATUS ENQUIRY message, then tested end sends the signalling point available response to test lead.
In addition, in the method, test lead receives the signalling point available response, and application server process is added in the routing table.
In addition, in the method, also comprise: after test lead adds application server process to routing table, indicate the M3UA layer can bearer service to the upper-layer user by Indication message.If the point coding in the point coding of tested end and the STATUS ENQUIRY message is inconsistent, then tested end sends the unavailable response of signalling point to test lead.Then, test lead receives the unavailable response of signalling point, if there has been application server process in the routing table, then application server process is deleted from routing table.
In addition, in the method, also comprise: after test lead receives the unavailable response of signalling point, indicate the M3UA layer temporarily can't bearer service to the upper-layer user by Indication message.And also comprise: after tested end was received STATUS ENQUIRY message, tested end determined that the apply property of application server is IPSP.
In addition, in the method, tested end is the IPSP client, and test lead is the IPSP server.
In addition, in the method, tested end is the IPSP server, and test lead is the IPSP client.

As shown in Figure 3, the point coding of IPSP Server is a.a.a, and the routed keyword point coding of the RC correspondence of the AS of IPSP Client is a.a.a also, belongs to correct corresponding relation.Flow process shown in Figure 4 is that the point coding of IPSP Server is a.a.a, and the routed keyword point coding of the RC correspondence of the AS of IPSP Client is c.c.c, belongs to the corresponding relation of mistake.
Idiographic flow is as follows:
Step S302, after AS activates, ASP under the AS does not directly add in the route and goes, but at first find its corresponding routed keyword by RC, send DAUD message, wherein affected point coding (Affective SPC) is filled in the point coding that comprises in the routed keyword of AS correspondence for this reason, and starts T1 timer, routine test routing state;
Step S304, when receiving the DAUD message of opposite end, the apply property of finding this AS is IPSP, does not remove to search the state of influenced point coding in the SCN territory.And relatively whether this signalling point point coding is identical with influenced signaling point code, the identical DAVA that then replys;
Step S306 when receiving opposite end DAVA message, relies on message RC field to find AS, and the ASP of the activation under the AS is added in the route, thinks that the point coding consistency desired result passes through, and indicates the M3UA layer can bearer service by MTP_RESUME message to the upper-layer user;
Step S308, when receiving the DAUD message of opposite end, the apply property of finding this AS is IPSP, does not remove to search the state of influenced point coding in the SCN territory.And relatively whether this signalling point point coding is identical with influenced signaling point code, inequality then according to protocol requirement, for non-existent point coding inquiry, replys DUNA;
Step S310 when receiving opposite end DUNA message, does not add any ASP in route;
Step S312, timer T1 then after, repeating step S302 sends DAUD to the opposite end, the message of returning by the opposite end judges whether the ASP that activates to be added in the route goes.Respond and should remove if receive the DUNA of opposite end, the current available route that is in the routing table avoids message to send to the opposite end.And indicate the M3UA layer temporarily can't bearer service to the upper-layer user by MTP_PAUSE message.
In sum, according to the present invention, the condition that generates by the control routing table and reach opportunity and eliminate above-mentioned call loss, and detect reaching by the timing in the running and reduce the wrong purpose of bringing call loss that changes as far as possible, improve M3UA signalling route reliability with this.
