Example Embodiment

[0031] In the drawings, the same reference numerals will be used for corresponding or similar elements.

[0032] The present invention relates to the management of a state memory suitable for storing state information, which is used for message-based communication between communication units in a communication system. According to the present invention, data messages transferred between units are defined or divided into multiple (ie at least two) message categories. Moreover, the state memory is divided into multiple (≥2) memory sections. Then, a memory portion is allocated or dedicated to storing state information associated with a given message category. Even in the case where several (not particularly important) states are stored in other parts of the state memory, this will allow one communication unit to access important state information during communication with other communication units.

[0033] Hereinafter, the present invention will be described and disclosed with refer...

Abstract

The present invention relates to management of a state memory (160) in a communications unit (100-1). The state memory (160) then stores states that are used in message-based communication with external units (100-2, 100-3, 100-4; 200) in a communications system (1). The data message communicated between the units (100-1, 100-2, 100-3, 100-4; 200) are defined into multiple message classes. Furthermore, the state memory (160) is divided into multiple memory portions (160-1, 160-2), where each such memory portion (160-1, 160-2) is assigned to store states associated with a specific message class. This will prevent overwriting important states with less useful states.

Description

technical field [0001] The present invention relates generally to memory management in communication systems, and more particularly to the management of state memory in such systems. Background technique [0002] Nowadays, data communication between communication units in different communication systems is showing an increasing trend. Typical examples are communication between computers connected by a communication system such as the Internet or a local area network and data communication between a mobile user device and a communication server or node or another mobile user device on a wireless communication system. [0003] Many application protocols used in data communications require specific information and data to be included in messages transmitted over the communications system. These data may be required to enable efficient session establishment, efficient delivery of data messages in the system and / or may be used by the receiving communication unit to interpret and...
