Abstract: A communication device using a current wireless network via a first access point confirms availability of a second access point before breaking the current connection. To confirm availability of the second access point, the communication device sends a power management message that causes the first access point to store packets during the power management period. After the connection to the second access point is confirmed, the second session may be put on hold using the same technique while the connection to the first access point is restored, the stored packets processed and the connection closed. Then the connection to the second access point may be reactivated and further communication made through the second access point.

Abstract: A filter expression is received at a wireless device assembly of a communication device. While a host assembly of the communication device is in a sleep mode, the wireless device assembly receives a signal having packet data, and determines whether the packet data contains a data pattern indicated by the filter expression. If the packet data contains the data pattern, the wireless device assembly communicates a wakeup signal to the host assembly for changing the host assembly from the sleep mode to an active mode. If the packet data does not contain the data pattern, the wireless device assembly does not communicate the wakeup signal to the host assembly.

Abstract: In a method and apparatus for providing memory efficient filtering of a received broadcast signal, a wireless device assembly compares a filter expression to packet data in the broadcast signal to determine whether the packet data contains a particular bit pattern indicated by the filter expression. The wireless device assembly is able to perform such filtering with an associated host assembly in a sleep mode or with that host in an active mode. If the host assembly is in a sleep mode, and if the packet data contains the particular bit pattern indicated by the filter expression, the wireless device assembly communicates a wakeup signal to the host assembly for changing the host assembly from the sleep mode to an active mode. On the other hand, if the packet data does not contain the particular bit pattern indicated by the filter expression, the wireless device assembly does not communicate the wakeup signal to the host assembly.

Abstract: A host assembly of a wireless device enters into a handshaking procedure with firmware of the wireless device to initiate entry into or exit from a host sleep mode. Before such entry or exit, the handshaking procedure may require the host assembly to send an initiation handshake signal to the firmware, and require the firmware to send a confirmation handshake signal back to the host assembly. Entry or exit may be delayed until after the confirmation signal is received. The confirmation signal may vary depending on the handshaking configuration and activation data, and the confirmation signal may vary depending on whether the wireless device is in a power save mode or not.
