  • Publication number: 20180352486
    Abstract: Signal load due to ping-pong of a wireless device between a wireless local area network (WLAN) access point (AP) and a cellular base station is reduced. The wireless device operates in a geographic region with signal coverage from more than one radio access technology (RAT) type of cellular serving cell as well as potentially coverage from the AP. An IP address used for incoming calls and the RAT serving the wireless device are part of a context. In some instances, when the wireless device changes context from the AP to a cellular base station and back to the AP (“ping-pong”), the context changes and a new IP address may be obtained via network signaling. Ping-pong is reduced by determining a quality estimate of cellular signals that relies on cell measurements from a mix of cellular base stations, where the mix of cellular base stations supports different cellular RATs.

  • Patent number: 10045259
    Abstract: In some embodiments, a cellular baseband processor communicates wirelessly and reports cellular metrics for both a first cellular RAT and a second cellular RAT. The cellular baseband processor may be configured to tune away, for a time interval, from the first cellular RAT to monitor for communications on the second cellular RAT. In some embodiments, the cellular baseband processor is configured not to report cellular metrics during the time interval to prevent a RAT manager from setting up a connection for voice calls on a WLAN RAT during the time interval. In some embodiments another processing element the RAT manager is configured to ignore cellular metrics from the cellular baseband processor during the interval. This may reduce signal load and power consumption, in some embodiments.
