Method, apparatus and system for realizing security detection in heterogeneous network

摘要

Provided are a method, apparatus and system for realizing security detection in a heterogeneous network. UE establishes cross-Evolved NodeB (eNB) double/multiple connections with a MeNB and a LPN in an access network which is a kind of heterogeneous network, the LPN is responsible for data distribution, and the distribution is layered by RB; the MeNB receives a report message from the LPN through a backhaul interface between the MeNB and the LPN, and the report message contains the data count sent/received between the LPN and the UE; and the MeNB transmits CP information with the UE to compare the data counts actually sent/received between the access network and the UE to detect whether there is insertion of an attacker or not. According to the present disclosure, the heterogeneous network is deployed with the MeNB and the LPN, so that joint transmission service is provided for the UE; and moreover, the security performance of the network is further improved, the present disclosure is applicable to various backhauls, and good joint transmission service can be securely and efficiently provided for the UE.

1. A method for realizing security detection in a heterogeneous network, wherein User Equipment (UE) establishes cross-Evolved NodeB (eNB) double/multiple connections with a Macro eNB (MeNB) and a Low Power Node (LPN) in an access network which is a kind of heterogeneous network, the LPN is responsible for data distribution, and the data distribution is layered by Radio Bearers (RB); the MeNB receives a report message from the LPN through a backhaul interface between the MeNB and the LPN, and the report message contains a data count sent/received between the LPN and the UE; the method comprising:
transmitting Control Plane (CP) information between the MeNB and the UE to compare data counts actually sent/received between the access network and the UE to detect whether there is insertion of an attacker or not.
