Abstract: A packet of data and a packet-identification value are transmitted to a network device having an identifier. The stored packet-identification value and the identifier are recorded. The stored packet-identification value is then increased and the process repeats. To receive data, an expected identification value is stored in association with the identifier. A packet and a packet-identification value are received from the network device. The identifier and an indication of receipt are stored. If the received value does not match the expected value for the identifier, the received value is stored. If the values match, the stored packet-identification value and identifier are recorded. If the received value exceeds the expected value, the stored packet-identification value, the identifier and the received identifier are recorded. Subsequently, the stored expected value is increased. The process repeats. Network devices and systems are described.

Abstract: A wireless transceiver decodes a receive signal to extract data contained in the receive signal. A processing block contained in the wireless transceiver then initiates a power-ON of the transmit radio portions of the transceiver prior to initiating a power-OFF of the receive radio portions. The technique enables the transceiver to meet timing requirements when operating in environments that require an acknowledgement to be sent in response to receipt of data.

Abstract: A wireless communication system provides call routing when the connection to a core network is lost. A base station wirelessly exchanges data packets associated with one or more communication sessions with one or more wireless communication devices. An Internet Protocol (IP) router scans the data packets to identify active users on the base station. The IP router generates a database of the active users. The IP router detects a loss of connection to the core network and determines which of the communication sessions can be maintained based on the database of active users. The IP router routes the data packets for the communication sessions that can be maintained back to the base station for delivery.
