Embodiment 1

[0127] The specific implementation process of the base station side in this embodiment is as follows Figure 6a As shown, the description is as follows:

[0128] Step 601: the base station works in the source cell on the source frequency point.

[0129] Step 602: The base station and the terminal agree in advance on the calculation method of the access stratum key of the terminal's target cell after spectrum switching, and the calculation method uses the access stratum key or encryption key of the terminal's source cell before spectrum switching stored by the base station. key management parameters.

[0130] The base station and the terminal agree in advance on the calculation method of the access stratum key of the target cell of the terminal after spectrum switching in a statically stipulated manner in the agreement.

[0131] In the LTE system, the key management parameters include NCC parameter values ​​and / or K eNB .

[0132] In an LTE system, the Access Stratum (AS) k...

Embodiment 2

[0153] This embodiment provides a calculation method for the base station and the terminal to pre-agree on the access stratum key of the terminal's target cell after spectrum switching: the terminal's target cell access stratum key after spectrum switching is The access stratum key of the source cell.

[0154] The specific implementation process of the base station side in this embodiment is shown in Figure 6c, and is described as follows:

[0155] Step 621: The base station works in the source cell on the source frequency point.

[0156] Step 622: The base station and the terminal agree in advance on the calculation method of the access stratum key of the terminal's target cell after spectrum switching: the access stratum key of the terminal's target cell after spectrum switching is that of the terminal's source cell before spectrum switching Access layer key.

[0157] The base station and the terminal agree in advance on the calculation method of the access stratum key of ...

Embodiment 3

[0172] This embodiment provides a calculation method for the base station and the terminal to pre-agree on the access layer key of the terminal's target cell after spectrum switching: the base station and the terminal use their own stored key management of the terminal's source cell before spectrum switching The parameter calculates the terminal's access stratum key of the target cell after spectrum switching.

[0173] The specific implementation process of the base station side in this embodiment is as follows Figure 6e As shown, the description is as follows:

[0174] Step 641: The base station works in the source cell on the source frequency point.

[0175] Step 642: The base station and the terminal agree in advance on the calculation method of the access stratum key of the terminal's target cell after the spectrum switching: the base station and the terminal respectively use the stored key management parameters of the terminal's source cell before the spectrum switching...

Abstract

The embodiment of the present invention discloses a security management method and equipment in a cognitive radio CR system, which relates to the field of wireless communication, and is used to solve how to perform security management of the access layer on the network side and the terminal side after spectrum switching is performed in the CR system The problem. In the present invention, after spectrum switching is performed, each terminal on the network side determines the The terminal obtains the access layer key of the target cell after the spectrum switching, and performs the security operation of the access layer according to the determined access layer key, thus solving the problem of how the network side and the terminal side perform spectrum switching in the CR system. Access layer security management issues.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a safety management method and equipment in a cognitive radio system. Background technique [0002] Radio communication spectrum is a precious natural resource. With the rapid development of wireless communication technology, the problem of poor spectrum resources is becoming more and more serious. In order to alleviate the shortage of spectrum resources, relevant departments and institutions have carried out monitoring and research on wireless communication spectrum , it is found that some frequency bands (such as TV frequency bands) are not used most of the time or in most regions, while some frequency bands have multi-system and multi-user competition at the same time, that is, the use of spectrum resources exists unbalanced phenomenon. It is against this background that the concept of Cognitive Radio (CR) came into being. The basic idea is: on the premise of not...
