Title
(EN) WIRELESS TERMINAL DEVICE, AND METHOD FOR CONTROLLING SAME
(FR) DISPOSITIF DE TERMINAL SANS FIL ET SON PROCÉDÉ DE COMMANDE

Abstract
(EN)
A wireless terminal device (1) used in a store-and-forward wireless network has a wireless communication unit (11), a memory (12), and a control unit (13). The memory (12) is linked to the wireless communication unit (11), and is configured to save multiple messages that are transferred in the wireless network. The control unit (13) is configured to adjust, on the basis of first information, the maximum number or the maximum storage length of the messages saved in the memory (12). The first information pertains to the extent to which the wireless terminal device (1) contributed to the success of transferring messages from a transmission-source node to a destination node via the wireless network. As a consequence, it is possible to provide, for example, an efficient memory control method which is suitable for a store-and-forward wireless network.
(FR)
La présente invention concerne un dispositif (1) de terminal sans fil servant dans un réseau sans fil de stockage et de retransmission et comprenant une unité de communication sans fil (11), une mémoire (12), et une unité de commande (13). La mémoire (12) est liée à l'unité de communication sans fil (11), et est configurée pour sauvegarder de multiples messages qui sont transférés dans le réseau sans fil. L'unité de commande (13) est configurée pour ajuster, en fonction des premières informations, le nombre maximum ou la longueur maximum de stockage des messages sauvegardés dans la mémoire (12). Les premières informations portent sur l'importance de la contribution du dispositif (1) de terminal sans fil au succès du transfert des messages d'un nœud de source de transmission à un nœud de destination par l'intermédiaire du réseau sans fil. Par conséquent, il est possible de fournir, par exemple, un procédé de commande de mémoire efficace qui est adapté à un réseau sans fil de stockage et de retransmission.
