Method and apparatus for mitigating interference between devices of different wireless wide area networks

摘要

A portable communication device operating of a first WWAN can receive an identifier from a WLAN access point indicating that one or more devices operating on a second WWAN are in the vicinity of the WLAN access point. In response, the portable communication device invokes an interference mitigation process while the identifier indicates that devices operating on the second WWAN are present.

主权项

1. A method, comprising:
receiving, by a wireless local area network (WLAN) transceiver of a portable communication device, in a signal transmitted by a WLAN access point, an identifier that identifies the WLAN access point; determining, by the portable communication device, that the identifier is indicative of a potential interference condition with respect to a wireless wide area network (WWAN) device separate from the portable communication device and the WLAN access point, and as a result, that an interference mitigation measure is to be invoked in operating a WWAN transceiver of the portable communication device to mitigate interference with respect to the WWAN device; and in response to determining that the interference mitigation measure is to be invoked, configuring the WWAN transceiver to avoid using at least one frequency band of a WWAN air interface while accessing a WWAN over the WWAN air interface.
