Problems solved by technology

User data is connected to different hosts, even if the same user's online data signaling may be distributed to different business hosts, the processing results must be aggregated before they can be used, increasing the difficulty of data management and performance overhead

Embodiment

[0020] 1) For 3G / 4G Internet data signaling (GTPU)

[0021] At the Ethernet layer, the standard protocol has a total of 14 bytes, of which the first two bytes of the destination address field are self-defined as 0xFE0xFE

[0022]

[0023] When the HUB sends Internet data signaling (GTPU) to the cluster host, the Ethernet layer must be rewritten, and the first two bytes of the destination address are filled with 0xFE0xFE

[0024] 2) For 3G / 4G command signaling (GTPC)

[0025] At the Ethernet layer, the standard protocol has a total of 14 bytes, among which the 13th and 14th fields of the protocol type are customized as 0xFF0xFF

[0026]

[0027] When the program is processed, the HUB forwarding signaling to the cluster host must be encoded at the data Ethernet level, and the cluster host must also be decoded at the data Ethernet level. The traditional TCP / IP programming model cannot be used, because the customized data packet has been Not a standard TCP / IP packet

Abstract

The invention discloses a 3G and4G mobile phone online signaling cluster processing optimization system. The system uses the central host HUB to access the core network GGSN to send mobile phone Internet access 3G / 4G signaling, and distributes it to the back-end service cluster host for processing services. There is at least one HUB and multiple can be configured. All HUBs are connected to the back-end business host according to the same rules. In a HUB host, the resources of HUB host are limited, the input signaling is lightened, the deep parsing signaling is reduced, and the hash value is divided according to the TE ID in the signaling to distribute the same user to the same thread and its bound CPU core for processing, so as to reduce the overhead of thread and memory switching. Also mapped to the back-end signaling distribution network card by hash value, and the HUB distribution network card and the back-end cluster back-end service host accept the network card point-to-point one-to-one connection. Thus, each business host processes the set of users whose TE IDs are hash-divided, and signaling for the same user is distributed to the same business host. The communication between HUB host and service host is based on the reformed internal bus.

Description

Technical field [0001] The invention relates to the technical field of data communication, in particular to a 3G and 4G mobile phone surfing signaling cluster processing optimization system. Background technique [0002] In the 3G and 4G network architecture, when mobile phone users access the Internet through the 3G / 4G wireless data channel, all users' online, offline, and base station switching signaling needs to pass through the GGSN network. In the GGSN network element of the mobile operator, the optical division multiplexing device is used to copy and drop multiple signaling data to third-party applications. The application side can implement a variety of value-added functions. For example, based on these signaling data, develop network quality detection, Application functions such as user online behavior analysis. These optical signals include online, offline, and location update 3G\4G command signaling (GTPC) and Internet data signaling (GTPU) for tens of millions of user...
