List (L1) of group participants is then stored (2.2), and notice (2.3) on event in group is sent to home network (200B) of the second client, in order to inform the network about the fact that the second client has become the new group participant. Client may then find out, participant of which active groups he or she is, without complicated search. ^ EFFECT: provision of possibility of guaranteed search or reception of information on membership in active groups of communication, so that the client may identify, participant of which groups he or she currently is. ^ 25 cl, 8 dwg |
