Abstract
The invention discloses a method and device for sending self-adaptive heartbeat data packets. The method comprises the steps that when the bandwidth availability ratio exceeds a preset threshold value, the cached heartbeat data packets are respectively analyzed through a core network to obtain protocol types, IMEI and the conveying direction of the heartbeat data packets; according to the conveying direction of the heartbeat data packets, integration processing is carried out on the cached heartbeat data packets by combining the protocol types or the IMEI; the heartbeat data packets after integration processing are transmitted according to destination IPs of the heartbeat data packets after integration processing. The bandwidth availability ratio is compared with the preset threshold value, the cached heartbeat data packets can be analyzed when heartbeat data occupy too many broadband sources, the heartbeat data packets are integrated by combining the conveying direction and the protocol types or the IMEI, the number of the heartbeat data packets is reduced, and the broadband sources occupied by the heartbeat data packets are lowered.
Description
Technical field
The present invention relates to the communications field, espespecially a kind of method and the device of realizing the transmission of self adaptation heartbeat data packets of load Network Based.
Background technology
The application of mobile Internet and the universal behavioural habits that changed user, stimulated the demand of user to Novel movable application, increasing to the dependence of instant messaging class or permanent online class business (as QQ, micro-letter, Fetion etc.).In order to ensure user's demand, need to remain permanent online to above communication service, permanent online in order to maintain application, application server at least needs to maintain a permanent link with customer mobile terminal.Keep IP to be connected by the small data packets that is called " heartbeat " or " maintenance activity " (hereinafter to be referred as heartbeat message) of frequently receiving and dispatching between application server and terminal in this permanent link open-minded; realize not the interrupting of permanent link (link keep-alive), to maintain user online status.
In permanent online mode; the long state that will always keep connection that is connected between mobile terminal and application server; and core net fire compartment wall between mobile terminal and application server need to periodically receive the heartbeat message from application server; therefore; application service will, to be less than the duration in required cycle of fire compartment wall, constantly send the heartbeat data packets that comprises heartbeat data to grow the keep-alive of connection to mobile terminal side.Fig. 1 is existing permanent online Business flow schematic diagram, and as shown in Figure 1, heartbeat data wraps in transmitting procedure and passes core net fire compartment wall, makes to connect effectively by this length of core net fire compartment wall, must not disconnect this long connection.
The object that sends heartbeat data packets due to application server is that long connection carried out to keep-alive, and therefore the data volume of heartbeat data packets is little, but transmission frequency is higher.Heartbeat data packets is generally the data volume of tens bytes, comprised packet recipient's terminal iidentification, with the mutual terminal of application server in the content such as the application program identification of installing and heart sequence number.In transmitting procedure in heartbeat data packets from application server to mobile terminal, need to experience Internet network, core net and cordless communication network.Owing to will keeping long a connection between each applications client and application server, therefore, a large amount of heartbeat datas wraps in frequent transmission and transmission between Internet network and core net, transmit heartbeat data packets in mobile communications network time, can take a large amount of bandwidth resources, increase network burden, reduce mobile network's performance.
Along with various low discharges, the long business connecting develop rapidly, cause heartbeat data in mobile Internet significantly to increase, increase network traffics, bring great load to mobile Internet.Heartbeat data packets is that network has brought great burden, has affected the performance of whole system.At present, for the problem of heartbeat data packets occupied bandwidth flow, propose to calculate heart beat cycle according to network load condition, deviation situation based on reference cardiac cycle self and the deviation situation of reference cardiac cycle and current heart beat cycle determine whether current heart beat cycle to recalculate, to realize the transmission cycle of dynamic adjustment heartbeat data packets, avoided webmaster or network element in the excessive situation of offered load because the heartbeat data packets transmission cycle arranges the important service that is not suitable for causing and is affected.Also have some the processing method of heartbeat data to be passed through to adjust the transmission cycle of heartbeat data packets, reduce owing to pushing application and send the kwh loss that heartbeat message brings, but this kind of method do not consider to send the situation of occupying the network bandwidth in the process of heartbeat data packets.
To sum up, the processing method of current heartbeat data packets, cannot reduce the bandwidth occupancy of heartbeat data packets, and heartbeat message has brought very big burden to network, affects systematic function.
