Embodiment Construction

[0049] The embodiments of the present invention will be further described in detail below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the embodiments of the present invention, rather than to limit the embodiments of the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the embodiments of the present invention.

[0050] refer to figure 1 , figure 1 It is a schematic flowchart of a method for establishing cluster communication provided by an embodiment of the present invention.

[0051] Such as figure 1 As shown, the method for establishing cluster communication includes:

[0052] Step 101, the calling terminal initiates cluster encryption communication, selects an encryption key, and sends the encryption key to the cluster scheduling server, so that the cluster scheduling ...

Abstract

The invention discloses a method and system for establishing cluster communication. The method includes: the calling terminal initiates cluster encryption communication, selects an encryption key, and sends the encryption key to a cluster scheduling server, so that the cluster scheduling server sends the encryption key to the called terminal; The calling terminal establishes an encrypted call with the called terminal, and enters encrypted communication without KDS, and the key is selected by the terminal that initiates cluster encrypted communication, avoiding heavy dependence on the key distribution server KDS, and reducing the calculation of KDS And communication burden, to avoid the situation that the whole system cannot run when KDS fails.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular to a method and system for establishing cluster communication. Background technique [0002] The trunking communication system is a dedicated communication system, which is used in command, dispatch, public security, emergency rescue, etc. In order to solve the voice encryption of the trunking call and improve the security of the trunking communication system, a method for trunking call voice is proposed in the prior art. The call encryption method of this method is generally as follows: all member terminals of the calling party and the called party respectively obtain the session key of this encrypted call from the Key Distribution Server (Key Distribution Sever, KDS) through the base station subsystem BBS during the encryption call establishment process; All member terminals of the called party send requests to enter an encrypted call to the BB...
