20140105030 | MEASUREMENT OF FIELD RELIABILITY METRICS - A system that incorporates teachings of the subject disclosure may include an access segment of a mobility network in which routers receive network traffic data from base transceiver stations, forward the network traffic data by way of aggregation routers, originate probe packets directed to a targeted one of the base transceiver station and the aggregation router to determine, by way of an expected reply to each probe packet, reachability of the targeted one of the base transceiver station or the aggregation router. A change from reachability to unreachability of the targeted one of the base transceiver station or the aggregation router is determined to be an indication of service impacted outage. Determined service impacted outages are logged. Reliability metrics, such as average uptime, are computed from reachability status to quantify the impact of service level outages perceptible by the mobile communication devices. Other embodiments are disclosed. | 04-17-2014 |
20130103939 | Securing Communications of a Wireless Access Point and a Mobile Device - In one or more embodiments, a network provider can receive a request to access a public network via a wireless network implemented via one or more wireless access points. The network provider can receive, via an unsecured wireless communication from a mobile device utilizing the wireless network and via a hypertext transfer protocol secure (HTTPS), an encryption key usable to secure wireless communications from the mobile device utilizing the wireless network. The encryption key can be encrypted via a public encryption key, received from the network provider or previously stored by the mobile device, associated with the network provider. The network provider can decrypt the encryption key and can provide the encryption key to a wireless access point implementing the wireless network and communicating with the mobile device. The wireless access point and the mobile device can communicate in a secure fashion based on the encryption key. | 04-25-2013 |
