  • Responding to a page message
    Patent number: 9578572
    Abstract: A method for responding to a page message is provided. The method can include a wireless communication device receiving a page message on a first channel of a first network; suspending a connection to a second network in response to receiving the page message; transitioning to a second channel of the first network prior to responding to the page message; and sending a response message responsive to the page message on the second channel.

  • Enabling receive diversity during paging channel timeline operation
    Patent number: 9271260
    Abstract: Enabling receive diversity based on detecting incorrect paging message length. A paging channel may be monitored. An indication of a paging message may be received on the paging channel. The paging message may include a message length field indicating a message length of the paging message. The message length field of the paging message may be received on the paging channel and decoded. It may be determined that the message length indicated in the message length field is incorrect. Receive diversity may be enabled for at least one subsequent paging occasion in response to determining that the message length indicated in the message length field is incorrect.

  • Apparatus and methods for state suspension in hybrid networks
    Patent number: 8868130
    Abstract: Methods and apparatus for suspending session state during hybrid network operation. In one exemplary embodiment, a cellular device uses a single-radio solution to support circuit-switched calls on a CDMA 1X network and packet-switched calls on LTE. Periodically, the cellular device tunes away from LTE and monitors CDMA 1X activity, and vice versa. During these tuned-away periods, the client device may suspend operation on the tuned away network for extended tune away intervals.
