The Frame that in the embodiment of the invention Frame receiving system is received is divided into following four kinds of Frame states, comprises not accepting state, receives but do not submit preservation state to, receive and submitted to preservation state and received and preserved success status.As shown in Figure 3, provide Frame state transition schematic diagram, for the new Frame that sends of a GSN node, if the Frame receiving system never received this Frame, then this Frame is " not receiving " state; This Frame is received the back state by the Frame receiving system and changes into " having received but submission preservation " state; The Frame receiving system can be regularly formed the Frame of some " receive but submit to and preserve " states packet and is submitted to the storage assurance device, and state is changed into " received and submitted to preservation state " state after Frame is submitted; After the storage assurance device was successfully preserved the call bill data and notification data frame receiving system of this Frame, the state of this Frame was changed into " having received and preserved success " state.
Have the formation of a data accepted frame state in the Frame receiving system, the formation of data accepted frame state is kept at the memory headroom of CG, writes down the number of frames of all Frames that received and to Frame state that should number of frames.The formation of data accepted frame state can have multiple implementation method, a kind of more excellent method is the state according to the Frame that has received, the state information of the Frame that corresponding number of frames record has received, state information comprises: first state information, the Frame state of expression corresponding data frame are for receiving but do not submit preservation state to; Second state information, the Frame state of expression corresponding data frame is for receiving and submitted to preservation state; The Frame state of third state information representation corresponding data frame is for receiving and preserved success status.
Another kind of more excellent method is according to the state of the Frame that has received, and number of frames is recorded three number of frames formations respectively, the first number of frames formation, and record has received but has not submitted the number of frames of the Frame of preserving to; The second number of frames formation, record has received and has submitted to the number of frames of the Frame of preservation; The 3rd number of frames formation, record has received and has preserved the number of frames of successful Frame.When the Frame that has received is not submitted to when preserving, the number of frames of this Frame is kept at the first number of frames formation; After the submitted preservation of the Frame that has received, the number of frames of this Frame is kept in the second number of frames formation, and in the first number of frames formation number of frames of this Frame of deletion; After the call bill data of the Frame that has received is successfully preserved, the number of frames of this Frame is kept in the 3rd number of frames formation, and in the second number of frames formation number of frames of this Frame of deletion.
Based on the formation of data accepted frame state, the embodiment of the invention provides a kind of Frame method of reseptance of call bill data, CG preserves the number of frames of the Frame that has received in certain hour scope or the certain number of frames scope and the Frame state of corresponding data frame, when CG newly receives Frame, number of frames according to this Frame judges whether record, if, think that then this Frame repeats, abandon this Frame, and take corresponding operating according to the Frame state, otherwise receive this Frame, as shown in Figure 4, comprising:
S401, when receiving the Frame that the GSN node sends, in the formation of data accepted frame state, search this Frame according to number of frames and whether be recorded in this formation, and take respective handling according to the Frame state, wherein be divided into following four kinds of situations:
If S402a finds the number of frames of this Frame and be not recorded in this formation, promptly this Frame is accepting state not, then receives and this Frame of buffer memory;
If S402b find the number of frames of this Frame be recorded in this formation and the Frame state for receiving but do not submit preservation state to, then abandon this Frame;
If S402c find the number of frames of this Frame be recorded in this formation and the Frame state for receiving and submitted to preservation state, then abandon this Frame;
If S402d find the number of frames of this Frame be recorded in this formation and the Frame state for receiving and preserved success status, then abandon this Frame, and return the response that successfully receives this Frame to the GSN node.
Wherein the Frame state can be judged according to the state information of the number of frames correspondence of this Frame, and perhaps the concrete number of frames state queue of preserving according to the number of frames of this Frame is judged.
The Frame method of reseptance of the repeating data frame that arrives according to the queue drop of data accepted frame state is judged when newly receiving Frame, can in time abandon the repeating data frame, guarantees that the call bill data of preserving does not repeat, and method is simply efficient; The opportunity that abandons the repeating data frame is reasonable, and can respond the GSN end timely and effectively to the repeating data frame that receives.
Behind Frame reception and the buffer memory, the Frame receiving system regularly takes out some data in buffer frame, is combined into a packet that comprises at least one Frame, is that each packet generates unique packet number.The Frame receiving system is submitted Frame with data packet form to the storage assurance device; the call bill data of each Frame is stored assurance device and sequentially is saved in external memory in the packet; adopted two states persistence object; guarantee the reliability of call bill data storage; state persistence object is kept in the permanence storage equipments such as hard disk; can adopt the form of file or database to preserve; two states persistence object comprises packet state persistence object and packet preservation location status persistence object, wherein:
Packet state persistence object comprises the number of frames of each Frame in the packet of submission, and packet of every submission can generate a packet state persistence object, and comprises packet number in the title of packet state persistence object;
Packet is preserved location status persistence object and is comprised the packet number that is stored last packet that assurance device successfully preserves.
Based on formation of data accepted frame state and two states persistence object, the embodiment of the invention provides a kind of Frame of call bill data to receive store method, as shown in Figure 5, comprises step:
S501, Frame receiving system extract at least one Frame and form packet from the Frame of buffer memory, can adopt the mode of timing extraction, and are the unique packet number of packet generation;
The number of frames that S502, Frame receiving system will be formed each Frame of packet is recorded in a packet state persistence object, and packet number is write in the title of this packet state persistence object;
S503, Frame receiving system send to the storage assurance device with this packet;
S504, storage assurance device are saved in external memory with the call bill data of each Frame in the packet, after preserving successfully packet number is recorded in packet and preserves location status persistence object, and return the response of the call bill data of successfully preserving each Frame to the Frame receiving system;
S505, when the Frame receiving system receive the storage assurance device response after, can in the packet state persistence object of correspondence, search the number of frames of the Frame of success preservation according to the packet number in the response, and in the formation of data accepted frame state, these Frame corresponding data frame states are refreshed to receiving and preserved success status, and reply the response that successfully receives this Frame to the GSN host node.
The Frame store method of the call bill data that the embodiment of the invention provides, guaranteed that Frame is saved in external memory reliably, need not to pick heavily, and avoid repeating data is stored in the external memory, feasible visit capacity to external memory reduces greatly.
The embodiment of the invention provides the automatic recovery method after abnormal conditions take place simultaneously.Abnormal conditions refer to the emergency case that some expections are outer, and for example network connects and hardware and software failure such as interrupts, the equipment burst is restarted, system's power down, software process are withdrawed from unusually.After abnormal conditions take place, because data accepted frame state queue record is at the memory headroom of CG, so can lose, CG need recover to have received in the formation of data accepted frame state and the number of frames of the Frame correspondence of successful preservation state, and the repeating data frame of avoiding the GSN node to send is repeated reception because lacking comparison information.Because packet state persistence object and packet are preserved location status persistence object and are forever preserved, so all before can taking place according to packet state persistence object recovery abnormal conditions have received and the number of frames of the successful Frame of preserving, it is added the formation of data accepted frame state, and the Frame state of corresponding data frame is set to receive and preserved success status, and method comprises:
After abnormal conditions take place, whether the maximum of packet number equates with the packet number that packet is preserved location status persistence object in the judgment data bag state persistence object, if, then the number of frames that writes down in each packet state persistence object is added the formation of data accepted frame state again, and the Frame state of corresponding data frame is set to receive and preserved success status;
If not, then delete the packet state persistence object of the maximum correspondence of packet number, and the number of frames that writes down in the remainder data bag state persistence object added the formation of data accepted frame state again, and the Frame state of corresponding data frame is set to receive and preserved success status.
On the different opportunitys of taking place at abnormal conditions, the automatic recovery method after the abnormal conditions that the embodiment of the invention is provided take place is described:
Abnormal conditions 1, when submitting packet to but abnormal conditions take place when not finishing the record of packet persistence object, as shown in Figure 6, the packet number of supposing the minimum of the packet state persistence object preserved in the current system is K, maximum packet number is K+N, because the record of packet persistence object is not finished, the record of packet preservation position persistence object is consistent with maximum packet number, i.e. the packet number that writes down in the packet preservation location status persistence object also is K+N.As can be known, packet number be K to the packet of K+N all is packets that success is preserved.In this case, before taking place with respect to abnormal conditions in the data accepted frame state formation after call bill data recovers, lacked and receive but do not submit the Frame number of frames of preservation state to, as shown in Figure 7.
Based on above description, automatically before taking place with respect to abnormal conditions in the formation of recovered data frame state, lacked receive but do not submit to preservation state Frame number of frames information and/or lacked the number of frames information that receives and submitted the Frame of preservation state to, but because this part Frame is not replied response frame, the GSN node can be retransmitted this part Frame behind certain hour, avoided losing of Frame.Simultaneously, be restored, repeat to receive when having avoided Data Receiving and preserved successful Frame owing to received and preserved the number of frames of success status.
Automatic recovery method after the abnormal conditions that the embodiment of the invention provides take place has greatly improved correctness and reliability that Frame receives.
The embodiment of the invention provides the length control method of a kind of data accepted frame state formation.The length of data accepted frame state formation can influence the speed of searching number of frames and Frame state, and queue length is long, can make seek rate slack-off, thereby the speed that causes abandoning the repeating data frame in the receiving course descends.On the other hand, sequence number and the Frame state of preserving the Frame of a large amount of preservations of success also can take a large amount of memory headrooms and external space, the formation of data accepted frame state is kept at memory headroom, and packet state persistence object is kept at external space.Therefore, the length of control data accepted frame state formation, the information that cleans out the expired Frame that receives and preserved success status in time is extremely important.
The embodiment of the invention provides a kind of data accepted frame state queue length control method, as shown in figure 11, suppose in the current system, packet number minimum in the packet state persistence object of preserving is K, the packet number that packet is preserved location status persistence object record is K+N, and this method comprises:
