A method for dynamically updating group information in cluster service

Abstract

The invention discloses a method for updating group information dynamically in group service. The method includes: carries identification to the communication terminal on the network side, if passes, the network side sends group information updating application to the communication terminal, after the communication terminal side receives the group information updating application, carries identification to the network side, if passes, the communication terminal side carries on group information update; if not, the communication terminal side refuse the update application of group information. If the communication terminal side does not pass the identification, the network side abolishes the group information update to the communication terminal side.

Description

technical field [0001] The invention relates to information security technology, in particular to a method for dynamically updating group information using two-way authentication in cluster services. Background technique [0002] The most important feature of the trunking service is that it can be dispatched and group called. The dispatching function of the trunking service refers to calling a certain number of communication terminals at the same time, so that these communication terminals can talk at the same time; The terminal initiates calls and conducts simultaneous calls at the same time, so as to achieve the effect of "response to all calls". The above communication terminals may be wired communication terminals or wireless communication terminals. Cluster services are widely used in private network users, such as military, railway, public security and other users. In the cluster business, there is often a need to dynamically update group information, which is mainl...

AI Technical Summary

Problems solved by technology

[0007] It can be seen from the above description that the process of dynamically updating group information in the prior art is to directly update group information, so the process of dynamically updating group information of communication terminals is very unsafe, and illegal networks may maliciously modify legitimate communications. The problem of terminal data also occurs that illegal communication terminals respond to the dynamic update of group information on the network side, making the network side think that legitimate communication terminals have successfully updated the group information
