Embodiment Construction
[0030] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0031] Such as figure 1 The structure diagram of the dynamic reorganization system in the cluster encrypted communication is shown. The encryption cluster system is composed of cluster encryption terminal (embedded password module), base station subsystem (BSS), dispatch subsystem (DSS), and dispatch subsystem (DSS) includes dispatch server (PDS), home register (PHR), dispatch Agent server (DAS), dispatcher cipher machine and key management center (KMC).
[0032] The PDS is the main control point of the call process, and is responsible for functions such as collection and distribution of trunking voice streams and generation of billing. PHR is responsible for the registration management of groups and members, and provides user service authority identification, statistics and billing functions. DAS controls the access and oper...
