Embodiment 1

[0030] Please refer to figure 2 , which is a flow chart of the X2 secure channel establishment method provided in Embodiment 1 of the present invention. As shown in the figure, it includes the following steps:

[0031] S210: The base station sends a notification message to the peer base station, where the notification message includes a security parameter set;

[0032] S220: Receive a reply message sent by the peer base station, where the reply message includes the security parameter value selected by the peer base station from the security parameter set;

[0033] S230: Establish an X2 secure channel according to the reply message.

[0034] Correspondingly, when the peer base station in the above steps receives the notification message, it will reply to it. The specific reply process is as follows: image 3 shown, including the following steps:

[0035] S310: The base station receives a notification message sent by the peer base station, where the notification message inclu...

Embodiment 2

[0076] Please refer to Figure 4 , which is an implementation block diagram of the base station provided in Embodiment 2 of the present invention. As shown in the figure, the base station includes a storage module 410 , an interface module 420 and a channel establishment module 430 . The storage module 410 is used to store a security parameter set; the interface module 420 is used to send a notification message to the peer base station, and the notification message includes the security parameter set; and the interface module 420 is also used to receive a message sent by the peer base station A reply message, the reply message includes the security parameter value selected by the peer base station from the security parameter set; the channel establishment module 430 is configured to establish an X2 security channel according to the reply message.

Abstract

Disclosed are an X2 secure channel establishment method and system and base stations. When a user terminal is switched from a community to another community and a notification message is sent from a base station to another base station, a security parameter set is sent for the another base station to select a security parameter value supported by the another base station and accordingly consultations are not required, the problem that the time delay is caused by the consultations or a secure channel cannot be established is solved, and the X2 secure channel can be established within the time which is tolerated by the communication switching, wherein each base station covers the corresponding community. The X2 secure channel establishment method comprises sending the notification message to the opposite end base station from the base station, wherein the notification message comprises the security parameter set; receiving a reply message sent from the opposite end base station, wherein the reply message comprises the security parameter value which is selected by the opposite end base station from the security parameter set; establishing the X2 secure channel according to the reply message.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and system for establishing an X2 safe channel, and a base station. Background technique [0002] The Long Term Evolution / System Architecture Evolution (LTE / SAE) network system project is the largest new technology research and development project initiated by the 3rd Generation Partnership Project (3GPP) in recent years. This technology with Orthogonal Frequency Division Multiplexing / Frequency Division Multiple Access (OFDM / FDMA) as its core is regarded as the mainstream technology in the evolution from 3G to 4G because it already has some "4G" features. [0003] Please refer to figure 1 , which is an architecture diagram of an LTE / SAE network system in the prior art. The LTE / SAE network system includes an evolved base station (eNB, eNodeB) and a Mobility Management Entity / Serving Gateway (MME / SGW, Mobility Management Entity / Serving Gateway) that manage...
