#CMT# #/CMT# The method involves assigning attribute characters (R2) to each subscriber units. A global revocation list (GCRL) is provided (R1) with identification data of unreliable subscriber units in a communication network. The subscriber units are assigned in groups (R3) as a function of the attribute characters, where the subscriber units of the respective group have the same attribute characters. A local revocation list (LCRL) is transmitted (R5) with identification data of unreliable subscriber units, which is assigned to the same group, at a respective group of assigned subscriber units. #CMT# : #/CMT# Independent claims are also included for the following: (1) a computer program product for the execution of method (2) a communication network #CMT#USE : #/CMT# Method for controlling data communication between subscriber units, particularly mobile phones or communication equipments coupled to vehicles like cars, airplanes or ships, in a communication network. #CMT#ADVANTAGE : #/CMT# The local revocation list is transmitted with identification data of unreliable subscriber units, which is assigned to the same group, at a respective group of assigned subscriber units, and hence ensures conveying only the revocated and updated information to the respective subscriber units. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a flow chart of a method for controlling data communication in a communications network.(Drawing includes non-English language text). R1 : Providing GCRL R2 : Assigning attribute characters R3 : Assigning subscriber units in groups R4 : Providing LCRL R5 : Transmitting LCRL R6 : Interaction between subscriber units of the same group. |
