Abstract
The present invention relates to management of a state memory in a communications unit. The state memory then stores states that are used in message-based communication with external units in a communications system. The data message communicated between the units are defined into multiple message classes. Furthermore the state memory is divided into multiple memory portions, where each such memory portion is assigned to store states associated with a specific message class. This will prevent overwriting important states with less useful states.

27. A method of managing a state memory adapted for storing state information applicable in a message communication between communications units in a communications system, characterized by:
-
defining at least two message classes of the messages communicated between said communications units; and
dividing said state memory into at least two memory portions, each memory portion being assigned for storing state information associated with a specific message class. and in that said state memory is arranged in a first communication unit and is allocated for storing state information used in message communication with a second communications unit. and in that said second communications unit requesting said first communications unit to allocate state memory space utilized for storing said state information used in said message communication with said second communications unit. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36)

means for defining at least two message classes of the messages communicated between said communications units; and
means for dividing said state memory into at least two memory portions, each memory portion being assigned for storing state information associated with a specific message class; and
in that said defining means is configured for defining said at least two message classes based on at least one of;
a priority type of said communications messages;
an application protocol used when generating said communications messages; and
a session type associated with communications messages. - View Dependent Claims (39, 40, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52)

a state memory managing unit, characterized in that said state memory managing unit comprises;
means for defining at least two message classes of the messages communicated between said communications unit and said at least one external communications unit; and
means for dividing said state memory into at least two memory portions, each memory portion) being assigned for storing state information associated with a specific message class; and
in that said defining means is configured for defining said at least two message classes based on at least one of;
a priority type of said communications messages;
an application protocol used when generating said communications messages; and
a session type associated with communications messages. - View Dependent Claims (41)
