Abstract

The invention discloses a method to process gateway information jam in mobile communication field, including: (1) when MGC justifies MG information abnormal, consider there is a fault in MG, and start up the MG process procedure. (2) the system takes measures to reduce MGC overhead MG occupies and number of information MGC transmits to faulty MG; (3) MGC continuously counts number of information from faulty MG, within a period of time, if judging there is no information jam in faulty MG, remove the special processing flow for faulty MG and take it as a normal MG to manage. The invention reduces the burden of gateway controller and gateway, relieves gateway information jam, and overcomes the disadvantage that because faulty MG occupies a large amount of MGC overhead or because of information jam of faulty MG, there is an influence on normal MG processing by MGC and even MGC is broken.

Description

The method of process gateway information jam

Technical field

The present invention relates to field of mobile communication, specifically, relate to the processing method of controlling and calling out message congestion in the isolation technics in the mobile communcations system.

Background technology

Along with mobile communcations system in the increasingly extensive application of every field such as economic and social life, mobile communcations system technology itself is also among fast development, from at present just at widely used second generation mobile communcations system, arrive ripe perfect third generation mobile system, the demand of user for communication system satisfied in technical development day by day.3GPP of International Standards Organization and 3GPP2 are responsible for the formulation and the modification of third generation mobile system international standard WCDMA standard and CDMA2000 standard respectively.In two types standard, H.248 agreement is extensively adopted by tissues such as 3GPP/3GPP2.

In the control and calling isolation technics of mobile communcations system, by the device separates with traditional control and call packing is MGC (Media Gateway Controller, gateway controller) and MG (Media Gateway, gateway) two parts, utilize the characteristics of IP/ATM transmission network, can realize on the one hand the mutual of voice, image, data, MGC (Media Gateway Controller, gateway controller) can also manyly more easily introduce professional on the other hand.H.248 agreement is used widely as the main media gateway protocols between gateway controller and the gateway.Under gateway controller control, H.248 agreement can finish the foundation of the media channel in the gateway and release, media channel and bearer path be connected with remove be connected, to the configuration of the attribute of media channel and bearer path; The operation of gateway controller be can also in gateway, finish, playback, audit etc. comprised media channel and bearer path; By agreement H.248, gateway can report gateway controller with self event.As can be seen, H.248 be a kind of control protocol up and down, the behavior of the complete control gateway of gateway controller.In the concrete use of agreement H.248, tend to relate to MG (Media Gateway, gateway), contents such as gateway controller, affairs, action and order, wherein, MG can be converted into a kind of medium type of network the media formats of another network requirement, and MGC is the part call state of control gateway connection media channel then.When MG break down or MG and MGC between link fault is arranged, MG has a large amount of message at short notice and is sent to MGC, because a MGC often manages a plurality of MG, thisly can exceed the disposal ability of MGC, thereby have influence on the management of MGC MG in the whole network from the congestion messages of fault MG.If very big and the duration is very long from the congestion messages quantity of MG, may exhaust the system resource of MGC, will cause the MGC collapse, still not having effective technology at present can address this problem.

Summary of the invention

Technical problem to be solved by this invention provides a kind of method of process gateway information jam, the a large amount of message of fault MG that can't overcome with the solution prior art take the MGC overhead, or because fault MG message congestion has influence on the shortcoming of MGC to normal MG processing even MGC collapse.

For achieving the above object, the present invention proposes a kind of method of process gateway information jam, it is characterized in that, may further comprise the steps:

The first step: the message of judging MG as MGC is unusual, i.e. receive the message that this MG is a large amount of in the short time, exceeds the disposal ability of MGC to this MG, thinks that then this MG breaks down, and starts the processing procedure to this MG;

Second step: system takes two kinds of measures to reduce MG and takies the overhead of MGC and the message count that MGC is sent to fault MG:

(1) in the message processing procedure of receiving from MG, analyze message identifier MID (the Message Identifier that obtains MG when decoding, the sign that message entity provides) time, in case find it is fault MG, stop processing immediately, only the request transaction of gateway is returned the response of affairs these affairs;

(2) be sent to the affairs of gateway for needs, analyze the MID of opposite end earlier, in case find that affairs are sent to fault MG, termination flow process immediately;

The 3rd step: MGC continues the message count of statistics from fault MG, in a period of time, if message congestion does not appear in failure judgement MG, just remove special processing flow process to this fault MG, it is managed as a normal MG.

The method of the invention is by the analysis and judgement of gateway controller to gateway fails, stop transaction analysis and the processing concrete to the fault gateway, thereby alleviate the load of gateway controller and gateway, alleviate the message congestion of gateway, solve a large amount of message of fault MG and taken the MGC overhead, or because fault MG message congestion has influence on the shortcoming of MGC to normal MG processing even MGC collapse.

Embodiment

Below in conjunction with the drawings and specific embodiments the method for the invention is described further.

Fig. 1 shows the method for process gateway information jam of the present invention, the message of judging MG as MGC is unusual, i.e. receive the message that this MG is a large amount of in the short time, exceeds the disposal ability of MGC to this MG, think that then this MG breaks down, start processing procedure this MG.System takes two kinds of measures to reduce MG and takies the overhead of MGC and the message count that MGC is sent to fault MG: (1) is in the processing procedure of receiving from the message of MG, the message identifier MID to MG (sign that Message Identifier (MID) message entity provides) when the decoding analysis, in case find it is fault MG, stop processing immediately, only the request transaction of gateway is returned the response of affairs these affairs; (2) be sent to the affairs of gateway for needs, analyze the MID of opposite end earlier, in case find that affairs are sent to fault MG, termination flow process immediately.MGC continues the message count of statistics from fault MG then, in a period of time, if message congestion does not appear in failure judgement MG, just remove special processing flow process to this fault MG, it is managed as a normal MG.

In method flow diagram shown in Figure 2, the message of judging MG as MGC is unusual, i.e. received a large amount of message of this MG in the short time, has exceeded the disposal ability of MGC to this MG, so think that this MG breaks down, has started the special processing flow process to this MG; The special processing flow process reduces MG from two aspects and takies the overhead of MGC and the message count that MGC is sent to fault MG: on the one hand for the processing procedure of receiving from the message of MG, when decoding analyze to the MID (domain name/domain name addresses/implementor name) of MG the time, in case find it is fault MG, stop processing immediately to these affairs, described affairs are made up of some actions, affairs have integrality, and action in the same affairs and order request order are carried out.Described action is formed by some command in combination, and action generally has concrete implication, and in particular cases, an action is made up of an order, and action is actually the sign of Management Information Base.Described order is the base unit that MGC and MGW realize interactive information, comprises the various command parameter in the order.Wherein all orders all will contain parameter Termination ID.On the other hand, being sent to the affairs of gateway for needs, also is the MID that analyzes the opposite end earlier, in case find that affairs are sent to fault MG, termination flow process immediately then, MGC just can not respond the message of fault MG like this, can initiatively not give fault MG transmission message yet.Generally, MG can recover the message congestion situation faster, and the easier recovery of fault MG is normal.In fact, MGC has only spent very little overhead, just finishes a large amount of processing from fault MG message.Therefore, can not influence management to other normal MG.

MGC continues the message count of statistics from fault MG, in a period of time, if message congestion does not appear in failure judgement MG, just remove special processing flow process to this fault MG, it is managed as a normal MG.In fact, the present invention can use the situation that a plurality of MG break down simultaneously simultaneously.

Below in conjunction with illustrated in figures 1 and 2, the specific embodiment of the present invention is described in detail as follows:

1, the disposal ability of supposing MGC is 1000 message from MG each second.10 MG of MGC condominium reason can be decided to be 100/second with each MG message congestion alarm threshold value like this;

If 2 in continuous 5 seconds, the message number that the MGC statistics sends over from MG, can think that all greater than 100 this MG fault occurred or occurred unusual with the link that is connected of this MG each second;

The response of the congestion messages that 3, stops this MG transmission message and stop this fault MG is come starts fault MG special processing flow process;

4, receive in the processing procedure from the message of MG, when decoding analyze to the MID (domain name/domain name addresses/implementor name) of MG the time, in case find it is fault MG, stop processing immediately to these affairs;

5, will be sent to the affairs of MG, also be the MID that analyzes earlier the opposite end, in case find that affairs are sent to fault MG, termination flow process immediately;

6, in 40 seconds, this MG does not have to occur not exceeding the alarm threshold value of message congestion, promptly removes the special processing flow process to this MG.It is managed as normal MG.

Embodiment can find thus, although a large amount of congestion messages of fault MG are sent to MGC, can not have influence on the processing of MGC to normal MG, or causes the collapse of MGC.
