Embodiment 1

[0050] Embodiment 1 is a kind of LTE multi-interface data backfill method provided by the embodiment of the present invention, refer to figure 1 As shown, the method includes:

[0051] Step 101, collect S1-MME or S10 interface messages, and obtain IMSI parameters.

[0052] Specifically, obtaining IMSI parameters can be achieved in any of the following ways:

[0053] Collect S1-MME interface message Attach Request or Attach Response to obtain IMSI parameters; or

[0054] Collect S10 interface messages Identification Request, Identification Response or Context Request to obtain IMSI parameters; or

[0055] Collect the Identity Response message sent by the user equipment UE to the mobility management entity MME, and obtain the IMSI parameter.

[0056] Step 102: Collect at least one globally unique temporary UE identifier GUTI in the S1-MME interface message, and establish a GUTI-IMSI mapping table with the IMSI parameter.

[0057] It is worth noting that the acquisition of the ...

Embodiment 2

[0070] Embodiment 2 is a kind of LTE multi-interface data backfill method provided by the embodiment of the present invention, refer to figure 2 As shown, the method includes:

[0071] Step 201, collect S1-MME or S10 interface messages, and obtain IMSI parameters.

[0072] Specifically, obtaining IMSI parameters can be achieved in any of the following ways:

[0073] Collect S1-MME interface message Attach Request or Attach Response to obtain IMSI parameters; S1-MME serves as an interface connecting user equipment UE and mobility management entity MME, and there are many identities for identifying UE in S1-MME interface messages, such as: IMSI , IMEI, IMEISV, and GUTI, where the first three identities of IMSI, IMEI, and IMEISV are fixed.

[0074] During the Attach Request / Attach Response process between the mobility management entity MME and the user equipment UE, the IMSI parameter can be obtained in the attach request message by detecting the interface message.

Abstract

The invention discloses an LTE multi-interface data backfill method. The method is characterized by comprising the following steps of collecting an S1-MME or S10 interface message to obtain IMSI parameters; collecting at least one globally unique UE identifier GUTI in the S1-MME interface message and establishing a UTI-to-IMSI mapping table with the IMSI parameters; obtaining session parameters in the S1-MME interface message and associating an S1-MME interface with an S6a interface according to the session parameters and a GUTI-to-IMSI mapping table; and associating at least one interface in the LTE with the S1-MME interface according to shared key parameters, and backfilling the data. According to the technical scheme disclosed by the invention, the accuracy for Internet surfing log query of a mobile user and network security incident retrospect, the backfill rate and the accuracy rate of identity information and the efficiency for data backfill can be improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and device for backfilling LTE multi-interface data. Background technique [0002] Nowadays, the 4G communication business is developing rapidly, and the LTE system is also constantly growing and improving. With the continuous expansion of the application range of the LTE system and the requirement of full network coverage, data backfilling has become an indispensable key technology for the LTE system. [0003] Mobile users will keep online logs in the process of surfing the Internet. When the user revisits the saved online logs, in order to avoid repeated authentication and other processes, the user can quickly complete the user's access to the online logs by means of data backfill. In addition, after a network security incident occurs, the intrusion source can be found according to the intrusion path, and the intrusion path can also be quickly formed throu...
