The first, the user needs the relevant information of own input group, often needs the situation of dynamic change for group information, and the frequent renewal group information of user's needs is to guarantee the information synchronization with system side;
Secondly, for the group information of terminal, the user can't be known the current state of this group, if this group does not exist, then the user can't be normally before new group of information of renewal and the group member get in touch;
The 3rd, need carry out again when system side before the division update group information of group, need notify the more group information of new terminal of all group members, could guarantee that terminal client can carry out work normally; And
At last, the terminal use can't be known the state that group is current in real time, for example whether this group is in effective scheduling district, if not being in effective scheduling district, this group do not use this group to communicate by letter normally, if the user can be known current group's state in real time, just can not use to have communicated in the group of effectively dispatching the district.
Therefore, need a kind of method that can safeguard the group information content quickly and easily.
