Title
(EN) METHOD FOR COORDINATING THE OPERATION OF A WIDE AREA NETWORK MODEM AND A PERSONAL AREA NETWORK MODEM IN A MOBILE COMMUNICATIONS DEVICE

Abstract
(EN)
A mobile communication device (102) contains both a WAN modem (122) and a PAN modem (134) which operate on interfering radio frequencies. To mitigate interference, and still permit real-time communication operation, the PAN is prevented from transmitting while the WAN is receiving (714). The PAN carries the real-time data via an active link (144) between the PAN modem and a remote device (142). The active link uses a retransmission protocol, which allows recovery of suppressed packets within a given period. The PAN modem is disabled for periods shorter than a maximum time which guarantees success transmission or retransmission of the PAN data. To further aid successful operation of the PAN retransmission operation, the WAN base station aggregates data into a single downlink burst.

L'invention concerne un dispositif de communication mobile (102) qui contient un modem WAN (122) et un modem PAN (134) qui fonctionnent sur des fréquences radio interférentes. Pour atténuer l'interférence, tout en permettant une opération de communication en temps réel, on empêche le PAN d'émettre pendant que le WAN reçoit (714). Le PAN transporte les données en temps réel via une liaison active (144) entre le modem PAN et un dispositif à distance (142). La liaison active utilise un protocole de retransmission, ce qui permet de récupérer des paquets supprimés pendant une période donnée. Le modem PAN est désactivé pendant des périodes plus courtes que le temps maximum garantissant une transmission ou retransmission fructueuse des données PAN. Pour mieux faciliter une opération fructueuse de l'opération de retransmission PAN, la station de base WAN rassemble les données dans une seule rafale de liaison descendante.
