Method and apparatus for performing neighbor scans on a wide area network in a mobile communication device operating a personal area network
First Claim
1. A method for performing neighbor scans on a wide area network in a mobile communication device operating a personal area network, wherein the wide area network and personal area network operate on similar frequencies, the method comprising:
- establishing an active link between a personal area network modem and a remote device, the active link using an in-frame retransmission protocol;
commencing a neighbor cell scan with a wide area network modem, comprising;
disabling transmission by the personal area network using the active link for a scan time; and
after an end of the scan time, enabling transmission by the personal area network using the active link for at least a minimum wait time;
wherein the scan time maximum is equivalent to a personal area network frame duration minus a last in-frame retransmission slot duration and the wait time minimum is equivalent to the last in-frame retransmission slot duration.

Abstract
A mobile communication device (102) includes both a wide area network (WAN) radio modem (122), and a personal area network (PAN) radio modem (134), which operate on similar frequencies. When the both the WAN and PAN modems are operating and carrying time-sensitive data, the WAN modem disables transmission by the PAN modem when the WAN modem is due to receive data from a WAN base station (406), including neighbor scans. The duration and frequency of disabling the PAN modem is controlled so that the retransmission is successful.

5. A mobile communication device, comprising:
-
a host processor; a wide area network modem operably coupled to the host processor; a personal area network modem operably coupled to the host processor; means for disabling transmission by the personal area network modem; wherein the wide area network modem and personal area network modem operate on similar frequencies; wherein upon the personal area network modem establishing an active link with a remote device, the active link using an in-frame retransmission protocol for transporting time-sensitive data, the mobile communication device is configured to scan for neighbor cells over the wide area network modem by; disabling transmission by the personal area network using the active link for a scan time; and after an end of the scan time, enabling transmission by the personal area network using the active link for at least a minimum wait time; wherein the scan time maximum is equivalent to a personal area network frame duration minus a last in-frame retransmission slot duration and the wait time minimum is equivalent to the last in-frame retransmission slot duration. - View Dependent Claims (6, 7, 8)
