Method for operating a wide area network modem and a personal area network modem in a mobile communication device

摘要

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.

1. A method for operating a wide area network modem and a personal area network modem in a mobile communication device, comprising:
detecting the presence of an active link between the personal area network modem and a remote device, wherein the active link carries real-time data to the remote device and uses an in-frame retransmission protocol; commencing a real-time data stream over the wide area network modem, the real-time data stream being received from a wide area network base station in a framed format; informing the wide area base station that the mobile communication device is presently supporting the active link over the personal area network modem; disabling transmission by the personal area network modem when the wide area network modem is due to receive information from the wide area network base station, wherein the personal area network modem transmissions are disabled for periods of time not exceeding a retransmission time of the in-frame retransmission protocol, and otherwise enabling transmission by the personal area network; and transmitting information over the wide area network modem to the wide area base station during a transmission time and wherein the transmission time has a duration not exceeding the retransmission time of the in-frame retransmission protocol.
