For example, the S5 interface can be divided into an S5-C interface and an S5-U interface. The S8 interface can be divided into an S8-C interface and an S8-U interface. The S5-C interface represents an S5 interface for transmitting signaling plane related data, and the S5-U interface represents an S5 interface for transmitting user plane related data. The S8-C interface represents an S8 interface for transmitting signaling plane related data, and the S8-U interface represents an S8 interface for transmitting user plane related data.
Specifically, network elements of the S5-C/S8-C interface are SGW-C and PGW-C. Network elements of the S5-U/S8-U interface are SGW-U and PGW-U. The network elements of the S11 interface (signaling plane interface) are MME and SGW-C, and the network elements of the S1-U interface (user plane interface) are eNB and SGW-C. Wherein, the signaling plane interface transmits gtpv2 signaling traffic, and the user plane interface transmits gtpU user plane traffic.

And determining the IP address of the eNB to be 10.109.83.21 according to the modified Bearer Request signaling message of the S11 interface. And determining that the IP address of the signaling plane of the SGW is 116.79.228.185 and the IP address of the user plane of the SGW is 116.79.228.186 according to the Create Session Request signaling message of the S5 interface or the S8 interface. And determining that the first IP address of the PGW is 220.206.186.248 and the second IP address of the PGW is 220.206.186.249 according to a Create Session Response signaling message of the S5 interface or the S8 interface.
After the IP addresses of the network elements are obtained, the first IP address of the SGW may be labeled on a side close to the SGW-C of the MME, the second IP address of the SGW may be labeled on a side close to the SGW-U of the MME, the third IP address of the SGW may be labeled on a side far from the SGW-C of the MME, the fourth IP address of the SGW may be labeled on a side far from the SGW-U of the MME, the first IP address of the PGW may be labeled on a side of the PGW-C, and the second IP address of the PGW may be labeled on a side of the PGW-U, and the final target network element topology with the labeled network element IP addresses may be as shown in fig. 4.
The embodiment of the invention determines the information flow direction between the target network elements according to the network element signaling data by acquiring the network element signaling data, thereby determining the target network topology according to the information flow direction between the target network elements.
