Fig. 1 is a flowchart of an embodiment of a data service transmission characteristic analysis method according to the present invention, as shown in fig. 1, the method includes:
step 100, acquiring a service data packet including a source IP address and a destination IP address sent by a mobile terminal from a Gn interface between a serving GPRS support node SGSN and a serving GPRS support node GGSN;
the data service transmission characteristic analysis method provided by the embodiment of the invention is suitable for end-to-end data services in each 3G mobile communication network of each region, wherein the 3G mobile communication network comprises the following steps: wideband Code Division Multiple Access (WCDMA), Time Division-Synchronous Code Division Multiple Access (TD-SCDMA), and the like. The following describes the transmission characteristics of data service in detail by taking WCDMA as an example, specifically: after the mobile terminal is attached to a GPRS service Support Node (SGSN), the mobile terminal initiates a PDP context activation process, the SGSN acquires an IP address of the GPRS Support Node (GGSN) through analysis, then initiates a PDP context creation process to the GGSN and carries out QoS parameter negotiation, a successful response returned by the GGSN contains information such as the IP address of the mobile terminal, and the like, when the PDP context is activated, the mobile terminal can send a service data packet, the service data packet is loaded between the SGSN and the GGSN through a GTP tunnel, and is converted into a common IP packet to carry out information interaction with other communication terminals after reaching the GGSN. In the process that the mobile terminal sends a service data packet to the GGSN through the SGSN, the service data packet sent by the mobile terminal is obtained from a Gn interface between the SGSN and the GGSN through a data service transmission characteristic analysis device, and the service data packet comprises a source IP address of the service data packet and a target IP address of a target terminal to be subjected to communication interaction. It should be noted that the data service transmission characteristic analysis apparatus may be disposed in the SGSN, or disposed in the GGSN, or may exist separately from other communication devices but is connected to the GGSN or the SGSN through the Gn interface, and may be adjusted according to actual application requirements, which is not limited to this.

the data service transmission characteristic analysis device analyzes the acquired service data packet to acquire a source IP address and a destination IP address, then inquires an IP address pool in the GGSN according to the destination IP address of the service data packet, and if the IP address pool is judged to contain the destination IP address, the IP address of the target mobile terminal receiving the service data packet is also distributed by the GGSN, so that the data service corresponding to the service data packet can be known to belong to a localized service, and the service data packet is the localized service data packet. Then, the data service transmission characteristic analysis device obtains source terminal position information corresponding to the source IP address and target terminal position information corresponding to the target IP address according to the terminal position information in the IP address pool and the home location register, wherein the source terminal position information specifically includes: the cell identifier and Radio Network Controller (RNC) identifier to which the source mobile terminal belongs, and the target terminal location information specifically include: and the cell identification and the RNC identification of the target mobile terminal.
