PDP Context request message in this step is the gn interface message after a kind of expansion, is the first masterslave switchover request described in the embodiment of the present invention.SGSN reports self tenability information to main GGSN by PDP Context request message.Main GGSN, can to standby GGSN this information synchronous when obtaining the tenability information of SGSN.

Step 92: main GGSN sends to SGSN and creates PDP Context response (Create PDP Context Response) message, the GTP-C address of active and standby GGSN is carried to (CTP-C (a), CTP-C (s)) in this PDP Context response message.

Main GGSN is according to the establishment PDP Context request message of the SGSN tenability information that carries received, know that SGSN supports the GTP-C address pair of active and standby GGSN, thus in PDP Context response message, carry the GTP-C address pair of active and standby GGSN, and send to SGSN.

Step 93:SGSN receives and creates PDP Context response (Create PDP Context Response) message, preserve in this message the GTP-C address of the active and standby GGSN carried to (CTP-C (a), CTP-C (s)), and by the GTP-C address of the main GGSN of signaling communication pointed of SGSN: CTP-C (a).

In the present embodiment, SGSN when obtaining the GTP-C address of active and standby GGSN to (CTP-C (a), CTP-C (s)), the GTP-C address by the main GGSN of signaling communication pointed: CTP-C (a).The benefit of process like this is, when having there is active and standby GGSN " dual-active " phenomenon in communication system, GTP-C address due to the main GGSN of signaling communication pointed of SGSN: CTP-C (a), therefore, SGSN can in the message received, filter out and comprise the GTP-C address that address is standby GGSN: the business association message except link test instruction and masterslave switchover instruction of CTP-C (s), namely the service message comprising address CTP-C (s) is filtered out, thus reduce the probability that exception occurs to judge SGSN, also the probability that customer service is interrupted just thus is reduced.

Ownership place does not support the SGSN that the GTP-C address of active and standby GGSN is right and roaming place SGSN, do not need the tenability information reporting himself to main GGSN, but the first floating IP address adopting the active and standby gn interface chain of command unit of active and standby GGSN to share, carry out Signalling exchange with active and standby GGSN respectively.

Usually, in masterslave switchover process, the business that on main GGSN, each module provides, all need take over carrying by each peer modules on standby GGSN.If active and standby GGSN upper part module carries out masterslave switchover and part of module does not carry out masterslave switchover, i.e. " part is switched ", then can cause Network Abnormal, even cause large area network failure.In order to avoid there is " part is switched " problem, the embodiment of the present invention introduces uniformity Switchover mechanism further, namely a module is determined in each module on standby GGSN, as the trigger point of masterslave switchover, issued by it and switch instruction, to make each module on standby GGSN carry out masterslave switchover simultaneously, namely carry out uniformity and switch.The method that the active and standby uniformity describing the embodiment of the present invention in detail and provide below in conjunction with Figure 10 is switched.

The method schematic diagram that Figure 10 switches for the active and standby uniformity that the embodiment of the present invention five provides.As shown in Figure 10, Gn-c (s) module on standby GGSN is the trigger point of masterslave switchover.When standby GGSN determines to carry out masterslave switchover, issue uniformity by Gn-c (s) module to other modules on standby GGSN and switch instruction; This uniformity switches instruction for triggering each module on standby GGSN, starts the adapter carrying of the business that each peer modules of main GGSN provides.

Each module on standby GGSN seizes the shared resource that main GGSN peer modules takies respectively, to take over the business that the main GGSN peer modules of carrying provides.Concrete, for chain of command, In-c (s) module refreshes the route of In-c (a) module in modes such as broadcasts, Gn-c (s) module seizes the first floating address that self and Gn-c (a) module are shared, Gi-c (s) module seizes the second floating IP address that self and Gi-c (a) module are shared, and Out-c (s) module refreshes the route of Out-c (a) module in modes such as broadcasts.For user face, In-u (s) module refreshes the route of In-u (a) module in modes such as broadcasts, Gn-u (s) module seizes the 3rd floating IP address that self and Gn-u (a) module are shared, Gi-u (s) module seizes the 4th floating IP address that self and Gi-u (a) module are shared, and Out-u (s) module refreshes the route of Out-u (a) module in modes such as broadcasts.If shared resource is taken by main GGSN peer modules, then, when each module on standby GGSN seizes shared resource, main GGSN peer modules can discharge respective resources.

As can be seen here, the present embodiment is when carrying out masterslave switchover, by introducing uniformity Switchover mechanism, complete the synchronous switching of each module on active and standby GGSN, avoid occurring that active and standby GGSN upper part module carries out masterslave switchover and part of module does not carry out the Network Abnormal that masterslave switchover causes, thus be conducive to the probability that reduces because these Network Abnormals cause customer service to interrupt.

In order to improve the accuracy that malfunction is collected, malfunction bleeding point can be set on main GGSN, and the trigger point of adjudicating using main GGSN as masterslave switchover.The module diagram of the main GGSN centralized collection malfunction that Figure 11 provides for the embodiment of the present invention.As shown in figure 11, can using the collection module of Gn-c (a) module in main GGSN as malfunction, all kinds of faults relevant by the main GGSN of this module centralized collection, as: physical interface fault, link failure and module failure etc.After all kinds of faults that main GGSN centralized collection self is relevant, total evaluation can be carried out based on these fault messages collected, whether carry out masterslave switchover to adjudicate.

Table 1: main GGSN fault total evaluation and switch decision rule example

Fault type	Capacitance loss	Traffic lost	Perform an action
				Physical interface/link failure	(0，x％)	(0，y％)	Alarm
Physical interface/link failure	[x％，w％)	[y％，v％)	Negotiation+alarm
				Physical interface/link failure	＞＝w％	＞＝v％	Switch+alarm immediately
Module failure	/	/	Switch+alarm immediately

As shown in table 1, main GGSN can categorised collection malfunction, and fault type can comprise: physical interface fault, link failure and EM equipment module fault.In addition, main GGSN also preset capacity can lose threshold value and traffic lost threshold value according to actual needs, and wherein, capacitance loss is the loss representing configuration amount, and traffic lost represents the variable quantity of service traffics before and after fault.In actual applications, redundant configuration amount when can plan according to carrier network and the service traffics of network statistics, set respective threshold.Such as: pre-set the first capacitance loss threshold value x% and the second capacitance loss threshold value w%, and 0 < x% < w% < 1; Pre-set the first traffic lost threshold value y% and the second traffic lost threshold value v%, and 0 < y% < v% < 1.

When main GGSN collects fault status information, all can perform the action of " alarm ", i.e. outputting alarm prompt information, to point out, main GGSN is current there occurs fault.In addition, main GGSN also can take the current capacitance loss of fault type, main GGSN and traffic lost, in advance judgment condition into consideration, so that main GGSN determines the current action needing to perform according to judgment condition.Concrete, can according to the influence degree of the fault collected to business, main GGSN also can perform judgment condition corresponding to " negotiation " and " switching immediately " action.The judgment condition pre-set is such as:

First is pre-conditioned: the type of fault is that physical interface/link failure, current capacitance loss amount are between the first capacitance loss threshold value preset and the second capacitance loss threshold value, i.e. [x%, w%) and current traffic lost amount between preset the first traffic lost threshold value and the second traffic lost threshold value between, namely [y%, v%).

Second is pre-conditioned: the type of fault is physical interface/link failure, current capacitance loss amount is more than or equal to the second capacitance loss threshold value w% and current traffic lost amount is more than or equal to the second traffic lost threshold value v%;

3rd is pre-conditioned: the type of fault is EM equipment module fault.

When the fault status information that main GGSN collects meet first pre-conditioned time, main GGSN performs " negotiations " action, namely to the flow process initiated active and standby negotiation for GGSN and switch; When the fault status information that main GGSN collects meet second pre-conditioned or the 3rd pre-conditioned time, main GGSN performs the action of " switching immediately ", namely triggers masterslave switchover by main GGSN.As can be seen here, Master Communication Equipment can based on the malfunction collected and the judgment condition pre-set, and automatic decision is the need of switching, thus the convenience that the system that improves administers and maintains.Below in conjunction with accompanying drawing, two kinds of situations such as switching are consulted to main GGSN triggering masterslave switchover and active and standby GGSN, is explained respectively.

Figure 12 carries out the interaction figure switching machinery of consultation for the active and standby GGSN that the embodiment of the present invention six provides.As shown in figure 12, the method that active and standby GGSN carries out switching negotiation comprises:

Step 121: main GGSN, according to faults itself status information, determines to need to carry out masterslave switchover.

The mode that main GGSN collects faults itself status information is unrestricted.Optionally, using Gn-c (a) module as the collection module of malfunction, collect fault status information.When the fault status information collected meet above-mentioned first pre-conditioned time, main GGSN determines to perform the action of " negotiation ".

Step 122: main GGSN sends masterslave switchover to standby GGSN and consults request (Switch Negotiation Request), determines whether to carry out masterslave switchover for asking standby GGSN.

Masterslave switchover is consulted to carry Trouble Report (Failure Report) in request (Switch Negotiation Request), and this Trouble Report comprises: the current capacities loss amount (Capacity Loss) of main GGSN and traffic lost amount (Service Loss).

Step 123: standby GGSN determines the business expected loss amount of self after switching, and by business expected loss amount, compares with the current capacities loss amount in Trouble Report and traffic lost amount, determines whether that masterslave switchover is carried out in agreement.

Standby GGSN in conjunction with the local state of the current capacitance loss amount of GGSN main in Trouble Report and traffic lost amount and standby GGSN, capacity and loading condition, can determine the business expected loss amount of self after switching.By this business expected loss amount, compare with the current capacities loss amount in Trouble Report and traffic lost amount.As this business expected loss amount, be less than the current capacitance loss amount of main GGSN and traffic lost amount, then agree to carry out masterslave switchover; Otherwise refusal carries out masterslave switchover.

Step 124: standby GGSN sends masterslave switchover negotiate response (Switch Negotiation Response), for notifying whether main GGSN agrees to carry out masterslave switchover to main GGSN.

If standby GGSN refusal carries out masterslave switchover, in masterslave switchover negotiate response, then carry " refusal " (Reject) parameter, and active volume (Capacity available) information and the Reason For Denial (Cause) of standby GGSN can be carried; Process ends.

If standby GGSN agrees to carry out masterslave switchover, then in masterslave switchover negotiate response, carry " acceptance " (Accept) parameter; Perform step 125a-step 126.

Step 125a-step 125c: standby GGSN sends masterslave switchover instruction (Switch) respectively respectively to SGSN1, SGSN2 and SGSN3, active and standby GTP-C address can be carried to (GTP-C (a) in this instruction, GTP-C (s)), for indicating SGSN1, SGSN2 and SGSN3 by its signaling communication pointer respectively, being switched by GTP-C (a) and pointing to GTP-C (s).

Step 126: the business that the main GGSN of standby GGSN adapter carrying provides.

In this enforcement, main GGSN introduces the negotiation mechanism of masterslave switchover: main GGSN is according to the fault status information collected, self define necessity when carrying out masterslave switchover, capacitance loss amount current for main GGSN and traffic lost amount are sent to standby GGSN, assessed in conjunction with the machine situation, capacity and loading condition by standby GGSN, to determine whether to accept to consult to carry out masterslave switchover.Visible, the present embodiment is switched based on masterslave switchover negotiation mechanism, can avoid switching causing larger loss because of standby GGSN adapter limited ability to user afterwards, and then is conducive to reducing the probability causing customer service to interrupt because masterslave switchover is uncomfortable.In addition, in above-mentioned steps 126, each module on standby GGSN can carry out masterslave switchover simultaneously, namely carries out uniformity and switches, the detailed description of its implementation and effect, see the corresponding record of the corresponding embodiment of Figure 10, does not repeat them here.
